Description

[Technical Field]

[0001] This invention relates to an artist management system (business-related invention) that uses IT to enable a matching business between amateur (including semi-professional) "artists" in various fields, such as musicians (musicians such as performers, vocalists, conductors, etc.), fine artists, sculptors, potters, and photographers, and event venues that plan and manage "events." The "events" of this invention include not only 1) events such as performances by amateur artists at real event venues, but also 2) events in which amateur artists participate in public events such as major debut auditions by appearing, performing, or showing their works. Furthermore, the "events" of this invention also include 3) events at event venues such as amateur festivals where amateur artists perform, perform, perform, exhibit, or exhibit their works for free or for a fee, and 4) internet events in which amateur musicians' original works are distributed online for free or for a fee. [Background technology]

[0002] Conventionally, matching between creators of original musical works and music-related people seeking them (see, for example, Patent Document 1), or matching between artists and producers (see, for example, Patent Document 2) have been proposed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-222287 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-341877 [Patent Document 3] Japanese Patent Application Publication No. 2018-022482 [Non-patent literature]

[0004] [Non-Patent Document 1] Nikkei XTECH "Understanding Blockchain in 3 Minutes": https: / / xtech.nikkei.com / atcl / nxt / column / 18 / 00187 / 030100001 / Summary of the Invention [Problem to be solved by the invention]

[0005] Many musicians seek opportunities to perform in front of an audience at commercial venues ("perform," in the music field of this application, refers to singing by vocalists, etc.; hereinafter, the same applies), and to release and distribute their music. Here, "commercial venues" include public amateur concert festivals, professional debut audition event venues, and virtual venues via communication, such as commercial online distribution sites. A small number of professional musicians enjoy the opportunity to perform at paid venues, such as live music clubs and concert halls. Professional musicians also enjoy the opportunity to distribute their music through major commercial music download sites. Here, "professional musician" is defined as someone who belongs to a record company (including a label) or an entertainment agency (including a music production company), or who appears, is introduced, or is featured in various media outlets, such as television, radio, and magazines (hereinafter, the same applies).

[0006] On the other hand, many amateur musicians (including semi-professional musicians; the same applies hereinafter) who generally lack the ability to promote themselves or negotiate, regardless of their talent, often find themselves unable to obtain opportunities to perform, perform, or present in commercial venues or to distribute their music on major commercial music download sites, unless they invest their own funds. As a result, amateur musicians with talent and promising potential may end up being buried without making a name for themselves. Even if an amateur musician is able to obtain an opportunity to perform, perform, or present (including distribution) in a commercial venue (including online music distribution sites), the amateur musician, who is in a weak position when it comes to signing a contract (performance contract) for performance, performance, or presentation (including distribution), may find themselves in trouble in fulfilling the contract. In such cases, the weak amateur musician may have no choice but to accept the consequences.

[0007] On the other hand, it is difficult for those planning to set up stores, performance venues, etc., and hold events, including music performances, in order to revitalize a particular area to gather a large number of amateur musicians within a limited budget. Similarly, when restaurant owners and operators of other commercial facilities seeking musicians to perform in their establishments, it is difficult for them to find talented and promising amateur musicians who fit the policies and atmosphere of their establishments. Furthermore, if amateur musicians cannot be attracted to event venues in virtual digital scenes such as the Internet (such as public music distribution sites), business opportunities between organizers, operators, and amateur musicians will be lost, and the synergistic effects of commercial benefits for both parties will not be expected. Of course, when audio content created and recorded by amateur musicians is collected through a public call for submissions and posted on a music distribution site, there is a possibility that contractual issues may arise between the operator and the amateur musicians, such as the audio content not being posted appropriately.

[0008] This type of problem is not limited to problems with opportunities for amateur musicians to perform, but can also arise when amateur artists in fields other than music (such as painters, sculptors, and other artists) seek opportunities to demonstrate their artistic abilities at various event venues.

[0009] (Object of the invention) This invention was made in consideration of these problems, and its main purpose is to use IT to match artists who are not fortunate enough to have the opportunity to perform or stream, or who are looking for a place to perform or stream, with event venues that are looking for artists with such aspirations, and to provide a system that prevents artists who are in a weak position to conclude and fulfill performance contracts and other contracts from getting into trouble with event venues, as well as to resolve any problems that may arise.

[0010] A secondary object of the present invention is to provide a system that can prevent data tampering. [Means for solving the problem]

[0011] The artist management system according to the subject matter of the present invention comprises a cloud server device having a database, an artist computer that transmits and receives signals to and from the cloud server device via the Internet, and an event venue computer that transmits and receives signals to and from the cloud server device via the Internet, wherein (A-1) the artist computer accesses the cloud server device via the Internet and transmits an artist registration information signal to the cloud server device that provides artist registration information about the artist, and the cloud server device, in response to receiving the artist registration information signal, sets an artist identification signal that identifies the artist, associates the artist registration information signal with the artist identification signal, stores the artist registration information signal in the database, and transmits the artist identification signal to the artist computer via the Internet, and (A-2) the event venue computer accesses the cloud server device via the Internet. (B-1) the artist computer transmits to the cloud server device, based on the on-screen display of the event venue registration information signal transmitted from the cloud server device to the artist computer via the Internet, a matching signal indicating the artist's intention to perform a match at the event venue, and (B-2) the cloud server device, in response to receiving the matching signal,(B-3) the event venue electronic computer accesses the matching site on the cloud server device based on the URL of the matching site provided by the received matching communication signal, and transmits a matching response signal to the cloud server device via the Internet, the matching response signal indicating the event venue's intention to accept the matching expression from the artist, based on the artist registration information displayed on the matching site; (C-1) in response to receiving the matching response signal, the cloud server device transmits to each of the artist's electronic computer and the event venue electronic computer a conference room access signal for accessing the conference room site on the cloud server device, whereby the artist and the event venue can negotiate for appearance with each other via the Internet at the conference room site. (C-2) the artist computer accesses the conference room site on the cloud server device via the Internet based on the received conference room access signal, while (C-3) the event venue computer accesses the conference room site on the cloud server device via the Internet based on the received conference room access signal, (C-4) each of the artist computer and the event venue computer transmits a negotiation signal indicating its intention to conduct the appearance negotiation with the other party on the conference room site of the cloud server device via the Internet to the conference room site of the cloud server device one by one according to the negotiation stage of the appearance negotiation, and (C-5) the cloud server device associates each of the artist's negotiation signal and the event venue's negotiation signal received from the artist computer and the event venue computer with the artist identification signal and the event venue identification signal at each negotiation stage of the appearance negotiation,The historical information of the appearance negotiations is sequentially stored in the database as a signal, and the cloud server device and each of the plurality of node computers form a block chain via the Internet.

DETAILED DESCRIPTION OF THE INVENTION

[0014] (Embodiment 1) In this embodiment, the configuration and operation of a music management system will be described as an "artist management system" that matches amateur musicians, who are an example of artists, with event venues. The advantages and effects of this music management system will be described after the description of embodiment 2.

[0015] <Outline of the Music Management System Configuration> Fig. 1 is a block diagram showing a schematic configuration of a music management system 100 according to this embodiment. The configuration of the music management system 100 shown in Fig. 1 is also used as the configuration of a music management system according to a second embodiment, which will be described later.

[0016] As shown in Figure 1, cloud server device 1, which forms the core of music management system 100, generally comprises server (cloud server) 3, which is the main body of device 1, database 4, which records data or information to be sent and received, and router 2, which sends and receives signals to and from the Internet 10. Here, server 3 itself and each site of server 3, which will be described later, operate in response to commands given by a predetermined program (including application software 8) that supervises and controls the entire music management system 100.

[0017] Furthermore, the musician's smartphone 5 is a "musician's electronic computer" that transmits and receives signals to and from the cloud server device 1 via the Internet 10 through the operation of the musician M. Note that instead of a smartphone, the "musician's electronic computer" may be any other electronic device that can connect to the Internet 10 and has a wired or wireless communication function, such as a tablet terminal, a laptop computer, a desktop computer, or a game device.

[0018] Furthermore, the event venue tablet terminal 6 is an "event venue computer" that transmits and receives signals to and from the cloud server device 1 via the Internet 10 through operations on the event venue E side. Similarly, instead of a tablet terminal, the "event venue computer" may be any other electronic device that can connect to the Internet 10 and has a wired or wireless communication function, such as a smartphone, laptop computer, desktop computer, or game console.

[0019] Furthermore, the external server 7 has on its website (app store) downloadable application software 8 dedicated to the present system 100, which is necessary for transmitting and receiving signals to and from the cloud server device 1 via the Internet 10. This application software 8 consists of (1) application software 8M for musicians and (2) application software 8E for event venues. Note that instead of storing these application software 8 in the external server 7 and allowing them to be downloaded, it is also possible to store these application software 8 in the server 3 itself and add to the server 3 a function that enables the application software 8 (8M, 8E) to be downloaded from the server 3, thereby enabling the use of the application software 8.

[0020] Here, "event venue E" in this embodiment (and also in embodiment 2 described below) is a broad concept indicating an entertainment venue or entertainment-like location having a space for holding "events" including musical performances and shows, or a broad term indicating various business forms. For example, "event venues" include live music venues, "stores" whose main business is food and beverage services, such as pubs, coffee shops, cafes, bars, and snack bars, indoor concert halls, outdoor spaces or outdoor open venues such as the rooftops of department stores, campaign venues for sales promotions, baseball stadiums, stadiums, other venues, plazas, areas, parks, religious facilities such as churches, etc.

[0021] <Music Management System Operation> A-0: Premise First, the operator / manager of the music management system 100 advertises a musical performance match between musician M and event venue E using the music management system 100. This involves using a promotional tool to call for registration from musician M and event venue E. For example, the advertisement for the music management system 100 is placed in advertising sections of flyers or music-related magazines, or in advertising sections on various websites on the Internet, social media, and video sites. The advertising section contains the URL (address) of the registration site on server 3 of the music management system 100 and / or a QR code (registered trademark) providing the URL of the registration site on server 3. Furthermore, the advertising section contains the URL of a website where application software 8 is stored on an external server 7, such as Google Play (registered trademark), and / or search terms, and / or a QR code (registered trademark) providing the URL of the website.

[0022] A-1: Musician registration information registration process A musician M (or a representative in the case of an individual or group) seeking a venue or opportunity to perform through the music management system 100 first operates, for example, a musician's smartphone 5 to register the following various pieces of information about musician M (referred to as "musician registration information") with the cloud server device 1.

[0023] Here, Fig. 2 is a diagram that schematically shows the process by which the musician's smartphone 5 registers various musician registration information with the cloud server device 1. In Fig. 2, images that are displayed on the display 5D of the musician's smartphone 5 based on signals transmitted from the server 3 during each step of the registration procedure are sequentially shown in Fig. 2(a) to Fig. 2(d). Also, Fig. 5 is a diagram that schematically shows the transmission and reception of electrical signals between the components 3, 4, 5, and 6 within the music management system 100.

[0024] First, the musician's smartphone 5 launches a browser and accesses the registration site on the server 3 via the Internet. Figure 2(a) shows the image displayed on the display 5D of the musician's smartphone 5 upon accessing the registration site. The upper part of the display 5D displays an image signal showing promotional information from the operator / manager of the music management system 100, while the lower part displays an image signal showing a "Musician Registration" button for registering musician registration information and a "Event Venue Registration" button for registering event venue registration information. During this process, musician M selects and touches the "Musician Registration" button on the display 5D. This causes the musician's smartphone 5 to send a signal requesting registration of musician registration information to the server 3 via the Internet 10 and the router 2.

[0025] Upon receiving such a signal, the server 3 sends a signal from the registration site to the musician's smartphone 5 via the router 2 and the Internet 10, which displays a screen on which multiple items to be entered as musician registration information are listed in sequence.As a result, the musician's smartphone 5 displays the image shown in Figure 2(b) on the display 5D. Here, the "musician registration information" which is information related to musician M himself includes, for example, "name," "date of birth," "gender," "contact information," "music genre (pop, jazz, rock, classical, etc.)," ​​instrument used (if the instrument used is guitar, enter "electric guitar" or "acoustic guitar"), organization information (individual or band / group (twin, trio, quartet, quintet, etc.)), activity history, nationality / region, email address, ID and password, etc. It should be noted that "vocal music" is also included in the "music" genre here. Therefore, musician M sequentially enters the corresponding data into each registration item field in the image shown in Figure 2(b). At this time, musician M may enter, for example, video or video data of his / her own performance or performance (for example, data of videos on YouTube (registered trademark)). When musician M has video data, still image data, or audio data of himself / herself playing or performing, or still image data such as photographs of himself / herself or his / her playing or performing, musician M touches the "Video / Still Image" button displayed on display 5D. This operation causes a signal to be sent from server 3 to musician's smartphone 5 via router 2 and Internet 10, displaying the "My Page" site screen (see Figures 1 and 5). As a result, the "My Page" site screen (not shown) is displayed on display 5D of musician's smartphone 5. Musician M transfers and records the video data, still image data, or audio data signals he / she owns onto the "My Page" screen, and then touches the "Save" button (not shown) on the screen.Through this touch operation, the video data, still image data, or audio data provided by musician M is transmitted via the Internet 10 and the router to the "My Page" site on server 3 and stored there. The screen on the display 5D of the musician's smartphone 5 returns to the screen shown in Figure 2(b). From this point on, the video data, still image data, or audio data provided by musician M is registered as "musician registration information." Note that in this system, the administrator or registrant may restrict the display of public information by selecting a button to make the registration information public or private. Once all registration information fields in the image shown in Figure 2(b) are filled out, musician M touches the "Registration Complete" button in the image. The musician's smartphone 5 then transmits a registration completion signal to server 3 via the Internet 10 and the router 2. Upon receiving the registration completion signal, the registration site on server 3 determines whether the registration information provided by the registration completion signal is correct. If the registration site of the server 3 determines that some of the registration information contains errors, it sends a signal to the musician's smartphone 5 via the router 2 and the Internet 10. The signal displays an image indicating the incorrect registration information, as shown in FIG. 2(c). In this case, musician M corrects each of the incorrect registration information on the display 5D and touches the "Edit" button after completing the corrections. This operation causes the musician's smartphone 5 to send a signal indicating the corrected musician registration information to the server 3 via the Internet 10 and the router 2. If the registration site of the server 3 determines that there are no errors in the registration information, it sends a signal to the musician's smartphone 5 via the router 2 and the Internet 10 indicating the details of each registration information, as shown in FIG. 2(d). As a result, the musician's smartphone 5 displays the image shown in FIG. 2(d) on its display 5D.If musician M wishes to change any of the registered information, musician M touches the "Change" button and sends a signal indicating the desire to make changes to server 3 via the Internet 10 and router 2. As a result, the registration site of server 3 again sends a signal providing the image shown in Figure 2(b) to musician's smartphone 5 via router 2 and the Internet 10. Subsequent operations and signal transmissions are as described above.

[0026] After receiving the registration completion signal, the server 3 determines that the musician registration information registration procedure is complete. It then assigns a "membership number" as additional information for identifying musician M and generates a "musician identification signal" that provides musician M's membership number, as well as information such as the ID and password stored on the registration site. The server 3 then transmits the musician registration information signal, which provides the "musician registration information" stored on the registration site, along with the musician identification signal to the database 4. In response to a control command signal from the server 3, the database 4 stores musician M's musician identification signal in the "musician registration information" area and associates the musician M's musician registration information signal with musician M's musician identification signal and stores it in the "musician registration information" area. The server 3 then sends an email signal containing musician M's membership number and ID, electronically recorded in the musician identification signal, to the email address of the musician's smartphone 5 via the router 2 and the Internet 10. This allows musician M to obtain information or data related to his or her membership number and ID. Furthermore, by entering the above ID and password information, Musician M can modify, add, and view the "Musician Registration Information" on the above registration site, as well as participate in the public information by applying for and viewing various public information on the site.

[0027] A-2: Event venue registration information registration process In the following, events that are held via communications, such as online distribution sites, will also be referred to simply as "event venues." In other words, the term "event venue" is a concept that includes virtual online events such as public events (including those held solely online).

[0028] Overview: An event venue computer accesses a cloud server device via the Internet and then transmits to the cloud server device an event venue registration information signal that provides "event venue registration information" (described below) related to the event venue that is the operator of the event venue computer. In response to receiving the event venue registration information signal, the cloud server device sets an event venue identification signal that provides at least a membership number for identifying the event venue, and stores the event venue registration information signal in a database in association with the event venue identification signal. At the same time, the cloud server device transmits the event venue identification signal, providing at least information on the membership number, to the event venue computer via the Internet. Details are as follows:

[0029] Details: First, suppose the organizer, operator, owner, or representative of Event Venue E, such as a live music venue, event hall, outdoor space, store, or online distribution site (hereinafter simply referred to as "Event Venue E"), 1) considers a plan to hold a musical performance or show as part of a local revitalization event. Alternatively, Event Venue E considers 2) a plan to hold a musical performance itself as an event at a store or other venue. Alternatively, Event Venue E considers 3) a plan to stage a simple festival concert "Murmoire" primarily featuring amateur musicians as a paid event. Alternatively, Event Venue E considers 4) an event in which amateur musicians participate in an audition contest for a major label debut, with each musician's live concert judged by Event Venue E. Alternatively, Event Venue E considers 5) a plan to distribute works submitted by amateur musicians via the Internet to a music distribution site, i.e., recorded music content by amateur musicians, over the Internet and hold a ranking popularity vote, as a "public event." As such, there are many different types of events that can be planned with the participation of amateur musicians. When event venue E considers planning such an event, it will use the music management system 100 shown in Figure 1 to match musicians who will participate in the event.

[0030] Therefore, the event venue E operates, for example, the event venue tablet terminal 6 of Figure 1 to carry out the procedure of registering the following various information about the event venue E (referred to as the aforementioned "event venue registration information") in the cloud server device 1.

[0031] Here, Fig. 3 is a diagram showing a schematic diagram of the process in which the event venue tablet terminal 6 registers various types of event venue registration information with the cloud server device 1. In Fig. 3, images displayed on the display 6D of the event venue tablet terminal 6 based on signals transmitted from the server 3 at each stage of the registration procedure are sequentially illustrated in Fig. 3(a) to Fig. 3(d). The disclosure of Fig. 5 mentioned above is also referred to for the description of this registration procedure.

[0032] First, the event venue tablet terminal 6 opens and accesses the registration site on the server 3 via a browser. Figure 3(a) is a schematic diagram of the image displayed on the display 6D of the event venue tablet terminal 6 upon accessing the registration site. During this process, the event venue E selects and touches either the "Event Venue Registration" button or the "Open Event Registration" button on the display 6D. In response to this button selection, the event venue tablet terminal 6 transmits a registration request signal S1 requesting the registration of "event venue registration information" or a registration request signal S2 requesting the registration of "open event registration information" to the server 3 via the Internet 10 and the router 2. In the following description, the above-mentioned "event venue registration information" and "open event registration information" will both be uniformly defined and described as "event venue registration information."

[0033] First, upon receiving the registration request signal S1 regarding the event venue registration information, the server 3 transmits a signal from the registration site to the event venue tablet terminal 6 via the router 2 and the Internet 10. The signal displays a screen listing multiple registration items to be entered as event venue registration information. As a result, the event venue tablet terminal 6 displays the image shown in FIG. 3(b) on its display 6D. That is, when the "Event Venue Registration" button in FIG. 3(a) is selected, the following multiple registration items are listed on the display 6D of the event venue tablet terminal 6 as "Event Venue Registration Information," which is information related to the event venue. For example, the following items are listed: "Venue Name," "Address," "Country," "Contact Information," "Business Type" (e.g., live music venue, restaurant, concert hall, etc.), "Desired Music Genre (e.g., J-Pop, jazz, rock, classical, etc.)," ​​"Venue Size (e.g., floor area, number of seats, etc.)," ​​"Whether or Not Tours of the Venue Are Available," "Desired Musician Formation Information (e.g., Individual or Band)," "Email Address," "ID," and "Password." Therefore, the event venue E sequentially inputs the corresponding data into each registration item field in the image shown in Figure 3(b). If the event venue E has, for example, video or image data recorded inside the venue (e.g., videos on YouTube®) or still image data such as photographs taken inside the venue, the event venue E touches the "Video / Still Image" button displayed on the display 6D. This touch operation causes a signal displaying the "My Page" site (see Figures 1 and 5) on the server 3 to be sent from the server 3 via the router 2 and the Internet 10 to the event venue tablet terminal 6. As a result, the "My Page" site screen (not shown) is displayed on the display 6D of the event venue tablet terminal 6. The event venue E transfers and records the signal for the video or still image data of the event venue onto the "My Page" screen, and then touches the "Save" button (not shown) on the screen.Through this touch operation, the signal for the video data or still image data provided by event venue E is sent via the Internet 10 and the router to the "My Page" site on server 3 and stored there, and the screen on display 6D of event venue tablet terminal 6 returns to the screen shown in Figure 3(b). From this point on, the video data or still image data provided by event venue E is registered as "event venue registration information." Once entry into all registration fields in the image shown in Figure 3(b) is complete, event venue E touches the "Registration Complete" button in the image of Figure 3(b), and event venue tablet terminal 6 sends a registration completion signal to server 3 via the Internet 10 and router 2. Upon receiving the registration completion signal, the registration site on server 3 determines whether there are any errors in the registration information provided by the registration completion signal. If the server 3 determines that some of the registration information is incorrect, the server 3 registration site transmits a signal via the router 2 and the Internet 10 to the event venue tablet terminal 6, displaying an image indicating the incorrect registration information, as shown in Figure 3(c). In this case, the event venue E corrects each incorrect registration information on the display 6D and touches the "Edit" button after completing the correction. This operation causes the event venue tablet terminal 6 to transmit a signal providing the corrected event venue registration information to the server 3 via the Internet 10 and the router 2. If the server 3 registration site determines that there are no errors in the registration information, the server 3 registration site transmits a signal via the router 2 and the Internet 10 to the event venue tablet terminal 6, displaying a message indicating "Registration completed with the following details" and the details of each registration information, as shown in Figure 3(d). As a result, the event venue tablet terminal 6 displays the image shown in Figure 3(d) on its display 6D. If the event venue E wishes to change some of the completed registration information, the event venue E touches the "Change" button and sends a signal indicating the desire to make the change to the server 3 via the Internet 10 and the router 2.As a result, the registration site of the server 3 again transmits a signal providing the image shown in Figure 3(b) to the event venue tablet terminal 6 via the router 2 and the Internet 10. Subsequent operations and signal transmission and reception are as described above.

[0034] On the other hand, if the "Register for Open Event" button in FIG. 3(a) is selected, the event venue tablet terminal 6 receives a signal from the server 3 and displays the image shown in FIG. 3(e) on the display 6D. Specifically, the following registration items are listed on the screen 6D of the event venue tablet terminal 6 as "Event Venue Registration Information," which is information related to the event streamed by the music streaming site. For example, fields for "Streaming Site Name," "Site URL," "Country Name," "Contact Information," "Business Type," "Desired Music Genre (J-Pop, Jazz, Rock, Classical, etc.)," ​​"Desired Musician Formation Information (Individual or Band, etc.)," ​​"Email Address," "ID," and "Password" are listed. Event venue E then sequentially enters the corresponding data into each registration item field in the image shown in FIG. 3(e). Here, an example of data entry into the "Business Type" field would be "Online Streaming." Then, when entry into all registration fields in the image shown in Figure 3(e) is completed, event venue E touches the "Registration Complete" button in the image of Figure 3(e), causing the event venue tablet terminal 6 to send a registration completion signal to server 3 via the Internet 10 and router 2. Upon receiving the registration completion signal, server 3's registration site determines whether there are any errors in the registration information provided by the registration completion signal. The subsequent operation or functions, signal transmission and reception, screen display, etc. of server 3's registration site and event venue tablet terminal 6 are equivalent to the displays in Figures 3(c) and 3(d) and the above-described description based on Figures 3(c) and 3(d), and therefore those illustrations and descriptions are incorporated herein by reference.

[0035] After receiving the registration completion signal, the server 3 determines that the registration procedure for the event venue registration information is complete. The server 3 then sets a "membership number" as additional information for identifying the event venue E and generates an "event venue identification signal" that provides the event venue E's membership number, as well as information such as the ID and password stored on the registration site. The server 3 then transmits the event venue registration information signal, which provides the "event venue registration information" stored on the registration site, along with the event venue identification signal to the database 4. In response to the control command signal from the server 3, the database 4 stores the event venue identification signal for the event venue E in the "event venue registration information" area and associates the event venue registration information signal for the event venue E with the event venue identification signal and stores it in the "event venue registration information" area. The server 3 then sends an email signal containing the event venue E's membership number and ID, provided by the event venue identification signal, to the email address of the event venue tablet terminal 6 via the router 2 and the Internet 10. As a result, the event venue E receives information or data about the venue's membership number and ID. Furthermore, by entering the above ID and password information, Event Venue E can modify, add, and view the "Event Venue Registration Information" on the above registration site, as well as participate in the public information by applying for and viewing various public information on the site.

[0036] B: Matching process from musician M B-1: Indication of intent to match (sending a matching signal) Summary: The musician's computer runs the musician's application software acquired via communication over the Internet, etc., and transmits a matching signal to the cloud server device via the Internet based on the event venue registration information signal displayed on the screen after the application is launched and transmitted from the cloud server device to the musician's computer via the Internet. The "matching signal" here refers to a signal that indicates a match between a musician who wishes to perform, present, or release (including streaming) music at an event venue of their choice (including online events) and the event venue. The details of this procedure are as follows:

[0037] Details: First, in response to musician M's operation, musician's smartphone 5 downloads and installs musician's application software (native app) 8M via the Internet 10 from the website (app store) of external server 7 or cloud server device 1 (see FIG. 1 ), thereby acquiring the application software 8M. Musician M may also acquire the musician's application software 8M from external server 7 via the Internet 10 before completing the registration procedure for the "musician registration information" described above. Then, musician's smartphone 5 runs the musician's application software 8M based on musician M's operation. In response to the activation of this app 8M, the matching site (see FIGS. 1 and 5 ) on server 3 of cloud server device 1 transmits signals via the Internet 10 to musician's smartphone 5, sequentially displaying matching screens as the procedure progresses, allowing musician M to select the event venue where he or she would like to perform, present, or release (including streaming) his or her music, based on the "event venue registration information" stored in database 4. Instead of using the native app 8M, the musician's smartphone 5 may (1) use a "web app (web application)" provided by the cloud server device 1, which does not require installation and can be actively operated from a browser using the Internet, to actively proceed through each process after the matching process based on the active operation of the musician M. Alternatively, instead of using the native app 8M, the musician's smartphone 5 may (2) use a "hybrid app (hybrid application)" downloaded and installed from an app store, to actively proceed through each process after the matching process based on the active operation of the musician M.Alternatively, instead of using the native app 8M, the musician's smartphone 5 may (3) use "PWAs (Progressive Web Apps)," which generally do not require downloading or installation by the user but are typically registered in an app store and then downloaded and installed from the app store to the terminal device by the user, thereby actively progressing through each step after the matching process based on the active operation of the musician M. PWAs are web applications that operate like native applications, operate offline, and also enable features such as push notifications. Alternatively, instead of using the native app 8M, the musician's smartphone 5 may (4) receive an environment (platform) such as a matching site on the server 3 of the cloud server device 1 based on the active operation of the musician M, thereby actively progressing through each step after the matching process. Here, a "platform" refers to a system created by programming and other processes on the cloud server device 1, taking into account the aspects visible to general users, and which can be operated from an internet-connected terminal device. The above-mentioned "platform" may be a service-type platform, a cloud-type platform, a cross (multi) type platform, a website (service) type platform, or a portal site-type platform (portal platform, etc.). Furthermore, instead of using the native app 8M, the musician's smartphone 5 may actively proceed through each process after the matching process by using (5) "TWA (Trusted Web Activities)." Here, each of the above-mentioned native apps, web apps, hybrid apps, PWAs, TWAs, and various apps and devices providing platforms, etc., is defined and referred to as a "cloud server connection means."

[0038] Here, Figure 4 is a diagram showing a schematic diagram of the matching screen at each step of the procedure, which the musician's smartphone 5 displays on its display 5D in response to a signal providing the above-mentioned matching screen sent from the matching site on the server 3.

[0039] First, as shown in FIG. 4(a), in response to the operation of the musician application software 8M, the matching site on the server 3 transmits to the musician's smartphone 5 a signal providing an image (including illustrations, text, video, audio, etc.) that allows the musician M to select an area or region where he or she wants to perform, present, or release (including streaming, etc.) his or her music, and the resulting screen is displayed on the display 5D. In response to the display of this screen, the musician M selects at least one area or region where he or she wants to perform, present, or release (including streaming, etc.), and upon completing the selection, he or she selects the "Pick Up" button on the screen by touching or otherwise operating it. In response to this operation, the musician's smartphone 5 transmits a signal providing information or data on all areas or regions selected by the musician M to the matching site on the server 3 via the Internet 10. However, these operations may also be performed on the matching site on the cloud server 3 after accessing the matching site on the server 3 of the cloud server device 1 via the Internet 10 via the musician application software 8M.

[0040] Next, as shown in FIG. 4(b), the matching site on server 3 sends a signal to musician's smartphone 5, sequentially displaying a row of the business types (live music venues, restaurants serving a certain cuisine, online streaming, etc.) of all event venues in the selected area or region based on the "event venue registration information" in database 4, and the resulting screen is displayed on display 5D. Upon receiving this display, musician M selects the business type of at least one event venue where he or she would like to perform, present, or present (including streaming) music, and selects the "Pick Up" button on the screen by touching or otherwise operating the button. In response to this operation, musician's smartphone 5 transmits a signal providing information or data on the business types of all event venues selected by musician M to the matching site on server 3 via Internet 10. If musician M wishes the screen on display 5D shown in FIG. 4(b) to be displayed again the next time a matching operation is performed, he or she can select the "Save" button on display 5D by touching or otherwise operating the button. Also, when musician M performs a selection operation such as touching the button "Venue offer" on the screen of display 5D shown in Figure 4(b), if there is an "offer" at this point, the business type to which the event venue making the "offer" belongs will be automatically selected.

[0041] Next, as shown in Figure 4(c), the matching site on server 3 sends a signal to musician's smartphone 5 to display a listing page screen showing all the selected event venues related to the business format based on the "event venue registration information" in database 4, and the screen is displayed on display 5D. Upon receiving this display, musician M selects one or more of the desired event venues on the screen and selects the "Pick Up" button by touching or other operation, and musician's smartphone 5 then sends a signal indicating the event venue to the matching site on server 3.

[0042] In response to receiving this transmission signal, the matching site of the server 3 transmits a signal to the musician's smartphone 5 via the Internet 10 to display a screen providing all of the registration information for the event venue, as shown in FIG. 4(d), based on the "event venue registration information" in the database 4, and the screen is displayed on the display 5D. When musician M selects the "video / still images" button on the screen by touching or otherwise operating the button, the matching site of the server 3 is linked in response to the transmission signal from the musician's smartphone 5. If video and still image data related to the selected event venue has been stored in the database 4 in advance, the matching site of the server 3 transmits a signal providing the video and still image data related to the event venue to the musician's smartphone 5. As a result of this transmission, video and still images related to the event venue are also displayed on the display 5D of the musician's smartphone 5. On the other hand, if the matching site of the server 3 determines that no video or still image data relating to the selected event venue is stored in the database 4, no signal providing video or still image data is sent to the musician's smartphone 5, and no video or still image relating to the event venue is displayed on the display 5D. Alternatively, a screen such as "No video or still image" is displayed on the display 5D.

[0043] If musician M determines from the event venue registration information displayed on the screen of display 5D that he does not wish to be matched with that event venue, musician M selects the "Back" button displayed on the screen of display 5D by touching or other operation. The matching site of server 3, which receives a signal transmitted from musician's smartphone 5 in response to such a selection operation, transmits a signal to musician's smartphone 5 via the Internet 10 to display the screen shown in FIG. 4(c), and the screen is displayed on display 5D. Musician M then selects one of the other desired event venues from the redisplayed matching screen shown in FIG. 4(c) and performs a selection operation such as touching the "Pick Up" button, and the same procedure is executed by transmitting and receiving signals between musician's smartphone 5 and the matching site of server 3.

[0044] On the other hand, if musician M determines from the event venue registration information displayed on the screen of display 5D that he or she wishes to be matched with that event venue, musician M selects the "Matching Registration" button on the screen of display 5D by touching or other operation. The matching site of server 3, which receives a signal from musician's smartphone 5 in response to such touching or other selection operation, transmits a signal displaying the "Matching Registration" screen shown in FIG. 4(e) to musician's smartphone 5 via the Internet 10, and the screen is displayed on display 5D. On this matching registration screen, as shown in FIG. 4(e), a check mark indicating the desired event venue is displayed in the column for the event venue with which musician M wishes to be matched. In this "Matching Registration," musician M selects the "Save to My Page" button on the screen of FIG. 4(e) by touching or other operation, and in response to such selection operation, the matching site of server 3 saves data indicating the event venue of the desired matched partner on musician M's "My Page Site." The matching site of the server 3 then sends a signal to the musician's smartphone 5 via the Internet 10 to display an image of "Saving to My Page Completed," and the image "Saving to My Page Completed" is displayed on the display 5D of the musician's smartphone 5 (see FIG. 4(f)). At the same time, the matching site of the server 3 causes the musician's smartphone 5 to display a "Done" mark instead of a "Check" mark in the right-hand column of the column for the event venue E of the desired matchmaker on its display 5D (see FIG. 4(f)).

[0045] If musician M wishes to further match with other event venues, musician M selects the "Back" button on the screen of display 5D by touching or otherwise operating the button. In response to such selection, the screen shown in FIG. 4(c) is displayed again on display 5D by sending and receiving signals between musician's smartphone 5 and the matching site of server 3. At this time, for event venues that have already been registered for matching, a "Done" mark is displayed in column 5B on the right side of the column for that event venue (see FIG. 4(c)). After that, the aforementioned procedure and signal exchange continues.

[0046] Finally, when all the event venues with which musician M wishes to be matched have been decided, musician M performs a selection operation such as touching the "Matching" button on the screen of Fig. 4(e). In response to such a selection operation such as touching, musician's smartphone 5 transmits a "matching signal" indicating musician M's intention to be matched with each of the event venues shown in Fig. 4(c) that musician M has selected as his / her matching partners, to the matching site of server 3 via the Internet 10.

[0047] Here, after running the musician's application software 8M, these series of operations can be performed by accessing a matching site on the cloud server 3 via the Internet 10 and operating on the cloud server device 1 to which the musician's smartphone 5 is electrically connected.

[0048] B-2: Transmission of matching transmission signal The matching site of the server 3, which has received the above-mentioned "matching signal" from the musician's smartphone 5, transmits a matching transmission signal to the event venue tablet terminal 6 at each event venue E that has been selected as a matched partner via the Internet 10. That is, as shown in FIG. 6(a), in response to receiving the above-mentioned matching signal, the matching site of the server 3 transmits a "matching transmission signal" indicating musician M's intention to match and providing the URL of the matching site on the server 3 as an e-mail signal to the event venue tablet terminal 6 at each event venue E that has been selected as a matched partner.

[0049] B-3: Matching response for each event venue E of the matched partner Upon receiving the matching transmission signal (email signal), the event venue tablet terminal 6 at each event venue E accesses the matching site of server 3 based on the URL of the matching site of server 3 in response to a click by the event venue E upon viewing the email. Figure 6(b) shows a screen displayed on the display 6D of the event venue tablet terminal 6 in response to this access, displaying the signal transmitted from server 3's matching site. The "Details" section at the top of the screen shown in Figure 6(b) displays all of the musician registration information (including video and still images) of musician M, who is seeking a match. The center of the screen shown in Figure 6(b) displays a "Matching Response Button" (YES, NO) for the event venue E, who has been selected as a matched partner, to indicate whether or not to accept the matching intention of musician M based on the musician registration information. Furthermore, the "Details" section at the bottom of the screen shown in Figure 6(b) displays the reason for the event venue E's "NO" decision. For this "details" section, a mechanism for selecting a pre-prepared comment may be adopted.

[0050] Here, based on the above musician registration information, it is assumed that event venue E, which has been designated as a matching partner, has decided to accept musician M's intention to match and to enter into contract negotiations with musician M for the performance, presentation, and release of music (including distribution, etc.). In this case, event venue E selects the "YES" button on the screen of display 6D by touching or other operation, and in response to this selection operation, the event venue tablet terminal 6 transmits a matching response signal indicating the event venue's intention to accept musician M's intention to match via the Internet 10 and router 2 to the matching site of server 3. On the other hand, if event venue E decides not to accept musician M's intention to match, it selects the "NO" button on the screen of display 6D by touching or other operation, and the event venue tablet terminal 6 transmits a matching response signal indicating the event venue's intention to not accept musician M's intention to match via the Internet 10 and router 2 to the matching site of server 3. At that time, the event venue tablet terminal 6 transmits a signal indicating the reason for rejecting musician M's expression of intent to match, along with the above-mentioned matching response signal, to the matching site of the server 3. Alternatively, the event venue tablet terminal 6 may simply transmit only a matching response signal meaning "NO" to the matching site of the server 3 without indicating the above-mentioned reason for rejection. Alternatively, the event venue tablet terminal 6 may not transmit any matching response signal.

[0051] C-1-1: When the matching partner's matching answer for "a certain event venue" is "YES" In response to receiving the matching response signal indicating a "YES" response, the matching site of the server 3 sends (1) the "YES" response signal and (2) a conference room access signal, as an email signal, necessary to access the conference room site, where musician M and one of the other event venues E can negotiate a performance at the "conference room" site on the server 3. That is, the matching site of the server 3 sends, via the Internet 10, to the email address of the musician's smartphone 5, a conference room access signal indicating the "YES" response and providing the URL of the conference room site and key information (key information) common to musician M and one of the other event venues E for accessing the conference room site. In addition, the matching site of the server 3 sends, via the Internet 10, to the email address of the event venue tablet terminal 6 of the corresponding event venue E, a conference room access signal (email signal) providing the URL of the conference room site and key information (key information) common to musician M and one of the other event venues E for accessing the conference room site. The conference room is a system constructed to enable two-way communication via the Internet 10, such as a video conference system, chat system, or digital message system, but it does not have to be limited to a real-time interactive communication system. The digital message system can be voice, text, or video messages, and is not limited to time-limited, self-destructing messages. Additionally, the music management system 100 and cloud server device 1 according to this embodiment do not need to be fully equipped with all of the video conference system, chat system, digital message system, etc. via the Internet 10 at the conference room site on the server 3.

[0052] C-1-2: When the matching partner's matching response for "a certain event venue" is "NO" In response to receiving a matching response signal indicating a "NO" answer from the event venue E, the matching site of the server 3 sends a signal indicating that the event venue E's intention is "NO" and a signal indicating the reason as an e-mail signal to the email address of the musician's smartphone 5. Alternatively, the matching site of the server 3 may simply send only a signal indicating that the event venue E's intention is "NO" to the email address of the musician's smartphone 5 without any reason. Alternatively, the matching site of the server 3 may not send any e-mail signal.

[0053] C-2: Access to the conference room from musician M Upon receiving a "YES" response signal and a conference room access signal email from the matching site of server 3, musician's smartphone 5 accesses the conference room site on server 3 based on the URL of the conference room site provided by the conference room access signal. In response to this access, the conference room site of server 3 sends musician's smartphone 5 a signal displaying a screen for inputting at least musician M's membership number, ID, and shared key information. In this case, a screen for inputting other information, such as musician M's already registered password, may also be added. Therefore, in response to musician M's information input operation, musician's smartphone 5 transmits a "first conference room access signal" that displays at least musician M's membership number, ID, (password), and shared key information to the conference room site on server 3 via Internet 10 and router 2.

[0054] C-3: Access to the conference room from the other party's event venue E Upon receiving an email containing a conference room access signal from the matching site of server 3, event venue tablet terminal 6 accesses the conference room site on server 3 based on the URL of the conference room site provided by the conference room access signal. In response to this access, the conference room site on server 3 sends a signal to event venue tablet terminal 6, which displays a screen for inputting at least the membership number, ID, and shared key information already assigned to event venue E. In response to an information input operation on the event venue E side, event venue tablet terminal 6 transmits a "second conference room access signal" providing at least the membership number, ID, and shared key information of event venue E via Internet 10 and router 2 to the conference room site on server 3. In this case, a screen for inputting other information, such as the password for event venue E, that has already been registered, may also be added.

[0055] C-4: Negotiations between musician M and event venue E in the conference room Overview: Each of the musician's computer and the event venue's computer transmits a "negotiation signal" indicating their intention to negotiate a performance with the other party via the Internet to the cloud server device's dedicated conference room site (shared screen) in real time, according to the stage of the negotiation. The conference room is a system capable of two-way communication via the Internet 10, such as a videoconferencing system, chat system, or digital message system, but it need not be limited to a real-time interactive communication system. The digital message system can include voice, text, and video messages, and is not limited to time-limited, self-destructing systems. Additionally, the music management system 100 and cloud server device 1 according to this embodiment do not necessarily require the conference room site on server 3 to be fully equipped with all of the functions via the Internet 10, such as a videoconferencing system, chat system, and digital message system.

[0056] Details: Upon receiving access signals from both the musician's smartphone 5 and the event venue tablet device 6 of the matched partner, the conference room site on the server 3 transmits a signal to the displays 5D, 6D of both the musician's smartphone 5 and the event venue tablet device 6, displaying a "private conference room" screen accessible to both parties based on a common "key information." This "private conference room" is a site where, by using a "tool" for mutual communication between the musician's smartphone 5 and the event venue tablet device 6, users can alternately write or speak (display) their intentions in real time on the screen via the Internet 10. Examples of such "tools" include Internet video conferencing (including voice messages only), text chat, or software such as Japanese word processing software.

[0057] FIG. 7 is a diagram showing the negotiation content displayed moment by moment on the screens 5D and 6D of such a "dedicated conference room," along with the time of the negotiation. In FIG. 7, "M" indicates the content of the negotiation signal indicating the musician M's intention to negotiate, and "E" indicates the content of the negotiation signal indicating the matched event venue E's intention to negotiate. In the case of a video conference via the Internet 10, video (including audio) recordings of the negotiation exchanges are saved. Even in cases where real-time communication is not possible, such as in a digital messaging system, text messages and video messages (including only audio messages) exchanged between the parties are saved, as shown in FIG. 7. The following are possible content of the performance negotiations provided by the negotiation signals alternately transmitted in real time to the "dedicated conference room" from both the musician's smartphone 5 and the event venue tablet terminal 6. For example, these include the date of the musical performance, show, or presentation (including streaming), the duration of each performance, the number of stage appearances per day, the performance fee (fee) per stage, whether or not the performance fee is guaranteed, the contract cancellation period, whether or not the other party is notified of the contract termination, whether or not damages are to be paid, and penalties for default. The performance fee to be paid to musician M could be set at XX% of the admission fee to the event venue. For example, 50% of the admission fee, which includes one drink, could be set as the performance fee to be paid to musician M. In addition, in the case of restaurants and other establishments, a per-person chargeback system (XX yen) could be considered. For example, a charge of 500 yen x number of people = performance fee. In any case, it is considered normal for event participants who come to event venue E, such as a store, to order other food and drinks from event venue E, so such a setup does not put event venue E at a disadvantage.

[0058] C-5: Saving the negotiation signal that gives the historical information (negotiation contents) of the appearance negotiation in the database 4 The conference room site of server 3 stores or records in database 4 the details of negotiations at each stage of the performance negotiations between musician M and event venue E. That is, server 3 receives negotiation signals from musician M and event venue E from both musician smartphone 5 and event venue tablet terminal 6 at each stage of the performance negotiations between M and E. Server 3 associates each of these signals with a musician-specific signal and an event venue-specific signal, and stores or records them sequentially in database 4 as signals providing historical information (negotiation details) of the performance negotiations. As a result, all of the expressions of intent displayed in real time on the conference room screen at each stage of the performance negotiations between musician M and his matched event venue E are stored and recorded in database 4 as historical information (negotiation details). For example, all of the negotiation details illustrated in FIG. 7 are stored in database 4 as "historical information." All negotiation signal data or history information data associated with the membership numbers, IDs, passwords, etc. of both M and E (musician-specific signals, event venue-specific signals) is stored for a predetermined period, for example, at least one month, in the database 4. As mentioned above, the negotiation signal data or history information data stored and recorded in the database 4 includes images, videos, images (moving images, still images), and audio.

[0059] C-6: Storage of memorandum information signals in database 4 If the negotiations between musician M and event venue E on the server 3's conference room site end in a breakdown (disagreement), musician M or the other party, event venue E, touches or otherwise selects the "Not Reached" button (see FIG. 7) on the display 5D of the musician's smartphone 5 or the display 6D of the event venue tablet terminal 6. In response to the signal generated by this touch or other selection operation, the server 3 sends a signal to the musician's smartphone 5 and the event venue tablet terminal 6 via the router 2 and the Internet 10 to clear the screen of the dedicated conference room site. At the same time, the server 3 executes a process to discard or erase all negotiation signal data or history information data associated with the membership numbers of both parties M and E and stored in the database 4. In this embodiment, the "agreement" of the performance negotiations between musician M and event venue E on the server 3's conference room site occurs when both parties M and E select the "Agreement" button shown in FIG. 7 by touching or otherwise selecting the button.

[0060] On the other hand, if musician M and event venue E reach a final agreement in their performance negotiations on the conference room site of server 3, both musician M and the other party, event venue E, touch or otherwise select the "Agree" button (see Figure 7) on the screen of the display 5D of musician's smartphone 5 and the display 6D of event venue tablet terminal 6. In response to this selection, both musician's smartphone 5 and event venue tablet terminal 6 send a signal indicating that the performance negotiations have been finally agreed to to the conference room site of server 3 via router 2 and the Internet 10. Upon receiving this final agreement signal, the conference room site of server 3 displays on the memorandum information site of server 3 the unsigned memorandum provided by the "unsigned memorandum information signal." This "memorandum (=contract)" is stored in database 4, into which basic items (such as performance conditions) based on the "memorandum (equivalent to a contract) template (contract template)" entered at the time of event venue registration are entered. At the same time, the conference room site on the server 3 sends a signal providing the URL of the memorandum information site as an email signal to the musician's smartphone 5 and the event venue tablet terminal 6 via the router 2 and the Internet 10. Here, the "unsigned memorandum information signal" refers to a signal providing an unsigned "memorandum" that lists all or the main details of the performance contract for musician M to perform, present, or release (including streaming) music at the event venue E in itemized form. In response to receiving this email signal, the musician's smartphone 5 and the event venue tablet terminal 6 each access the memorandum information site on the server 3. As a result, an image of the signal providing the unsigned "memorandum," such as that shown in FIG. 8, is displayed on the display 5D of the musician's smartphone 5 and the display 6D of the event venue tablet terminal 6. In response to the common screen display (shared screen display) of this unsigned memorandum, the musician's smartphone 5 and the event venue tablet terminal 6 each communicate with each other to check each clause of the unsigned memorandum, and if there are any parts that need to be revised, they are revised with the other party's consent.In this case, amendments are negotiated via the Internet 10 on a shared screen, such as via Skype's chat function, or amendments and additions are made via Skype chat. Then, the musician's smartphone 5 and the event venue tablet 6 each finalize the contents of each clause of the unsigned memorandum and sign the signature field on the unsigned memorandum screen. In this case, the name of musician M and the name of event venue E are automatically added and reflected in the signature field of the unsigned memorandum. Musician M and event venue E each press the corresponding "Final Confirmation" button on the screen of FIG. 8 by touching or other selection operation. In response to such selection operation, the memorandum information site of server 3 displays a "Final Confirmation" image (not shown) on the display 5D of musician's smartphone 5 and the display 6D of event venue tablet 6 within the unsigned memorandum screen. Alternatively, musician M and event venue E each press the corresponding "Final Confirmation" button on the screen of FIG. 8 by touching or other selection operation. Then, in response to such touching or other selection operation, the memorandum information site of server 3 automatically displays and adds musician M's name and the name of event venue E to the signature field of the unsigned memorandum on display 5D of musician's smartphone 5 and display 6D of event venue tablet terminal 6. Then, by selecting the final confirmation button as proof of final acceptance of the memorandum, one of mobile devices 5, 6, musician's smartphone 5 or event venue tablet terminal 6, which added the signature, creates a "final memorandum information signal" (including the memorandum serial number) that provides the final "memorandum" with the signatures of both M and E, and transmits the "final memorandum information signal" (including the memorandum serial number) to the memorandum information site of server 3 via Internet 10 and router 2. The memorandum information site in server 3 that has received the final memorandum information signal (including the memorandum serial number) generates a "memorandum information signal" (including the memorandum serial number) that provides a "memorandum" (=contract) signed by both parties and containing the final contract contents without any seals, based on the final memorandum information signal (including the memorandum serial number), and sends the memorandum information signal (including the memorandum serial number) to) is associated with the musician-identifying signal and the event venue-identifying signal and stored in database 4 as "memorandum information." This "memorandum information" indicates the contents of the performance contract and is important information or evidential material for parties M and E, so it is stored in database 4 for a longer period than the storage period for the negotiation signals described above. For example, the memorandum information is stored in database 4 for at least six months to one year. Note that the digital data of the final, signed memorandum (contract) provided by the memorandum information signal does not contain data on the seals of both parties. However, data on the seals of both parties may be included in the digital data of the final, signed memorandum (contract) by using various sealing technologies such as electronic seals. In addition, with regard to the creation and storage of digital data of memorandums (contracts) "signed by both parties" and "without seals," or "signed by both parties" and "with seals," memorandum information signals that provide a "memorandum," which is a contract in the form of digital data, formed by both parties using electronic tool devices such as electronic pens or electronic tool devices such as electronic pens and electronic seals, on the screens of various terminal devices (smartphones, tablet devices, PCs, etc.) connected to communication infrastructure lines such as the Internet, may be generated on the cloud and stored in Database 4. Alternatively, with regard to the creation and storage of digital data of memorandums (contracts) "signed by both parties" on the cloud, various authentication technologies such as biometric authentication technology may be combined with AI to create a message such as, for example, "Party XX's voice approved the contract with contract document number XX." " The digital data of the agreement, which is made up of linking together recorded video or audio data of a scene such as this, the biometric authentication data of the parties themselves, and detailed data in the memorandum, can be generated and stored on the cloud as digital legal evidence data that serves as "proof" of the "establishment of the contract and the specification of the contract contents" regarding the performance contract, that is, as digital data of a "memorandum information signal" that provides a memorandum (contract) "signed by both parties." More specifically, a) When legal evidence data consisting of digital data of a signature or digital data of both a signature and a seal (stamp) contained in the digital data of a relevant document such as a memorandum (contract), a confirmation letter (described below), a memo, or other "legal evidence document equivalent to a contract" is generated on the cloud as digital data of a "memorandum information signal" that gives a memorandum (contract) "signed by both parties" and is recorded and stored in a database, and a) By utilizing various biometric authentication technologies such as voice recognition (voice voiceprint), fingerprint / palm print recognition, finger vein recognition, facial recognition, iris (rainbow) recognition, ear acoustic recognition, XR, ultra-high definition video of 8K or more, holograms (3D holograms, avatars (characters that act as your own avatar), etc.), and AI, the biometric authentication data (voice recognition, facial recognition, etc.) of each party may be linked to the agreement and contract settlement information data between the parties (recorded video, recorded audio, images, text, etc.) and data on relevant documents such as memorandums (contracts) or "legal evidence documents equivalent to contracts," and this legal evidence data may be generated on the cloud as digital data of a "memorandum information signal" that provides a memorandum (contract) "signed by both parties," and recorded and stored in a database. Therefore, it should be noted that in this embodiment, the term or concept of "signed by both parties" in the "memorandum information signal" that provides a memorandum (contract) "signed by both parties" is understood in a broad sense, including the case that corresponds to the above-mentioned A) as well as the case that corresponds to the above-mentioned B), that is, it refers to "signed by both parties" in a broad sense. In the following description, the term "signed by both parties" in the broad sense above, or simply the term "signed by both parties" will be used. The memorandum information site on Server 3 then sends a "memorandum information signal" (including the memorandum serial number) providing the details of each contract in the "memorandum" as a file attached to an email signal via Router 2 and the Internet 10 to the email addresses of Musician's Smartphone 5 and Event Venue Tablet 6. Upon receiving this email signal, Musician's Smartphone 5 and Event Venue Tablet 6 each output the "memorandum" from the attached file, and both Musician M and Event Venue E retain the output or printed memorandum as evidence of the performance contract. Alternatively, the memorandum information site on Server 3 may send an email signal via Router 2 and the Internet 10 to the email addresses of Musician's Smartphone 5 and Event Venue Tablet 6, with the details of each contract in the "memorandum" provided by the "memorandum information signal" (including the memorandum serial number) directly written in the body of the email. In this case, the musician's smartphone 5 and the event venue tablet terminal 6 each save the text of the email provided by the received email signal on their respective terminals 5 and 6, or output the text of the email as a printed document. Alternatively, the memorandum information site on the server 3 may send an email signal via the router 2 and the Internet 10 to the email addresses of the musician's smartphone 5 and the event venue tablet terminal 6, providing the URL (location information) of a site containing a file (e.g., a PDF file) containing the details of each contract in the "memorandum" provided by the "memorandum information signal" (including the memorandum serial number). In this case, the musician's smartphone 5 and the event venue tablet terminal 6 each access the site at the URL provided by the email signal, download the file containing the details of each contract in the "memorandum" from the site, and save the file on their respective terminals 5 and 6. This allows both musician M and event venue E to save and retain the "memorandum" data on their respective terminals 5 and 6.Furthermore, the server 3 stores the signal providing information such as the membership number of the musician M who has reached the point of creating a "memorandum" with the event venue E in the "musician registration information" of the database 4 as one of the signals providing the number of agreed-upon times and the number of performances or shows. This number of agreed-upon times and the number of performances or shows becomes one of the indicators or parameters showing the future potential of the musician M. At this point, the data or information of the memorandum reference number becomes one of the data or information contained in the musician-specific signal and the event venue-specific signal mentioned above.

[0061] D: Disclosure request from musician M Amateur musician M, who has entered into a performance contract with event venue E through this system 100, is essentially a weaker party compared to event venue E. Therefore, musician M may be involved in contractual disputes before, during, or after the performance of the contract, such as unpaid performance fees. In such disputes, musician M must file a protest with event venue E and seek to resolve the issue. In such cases, musician M would be grateful if he or she could retain the full content of the intentions expressed by both parties during the performance negotiations and any memorandums agreed upon between the two parties as evidence and present them to the other party, event venue E, as evidence supporting his or her claims. This system 100 has the following information transmission functions that can deal with such disputes.

[0062] Suppose musician M, experiencing trouble with contractual performance, launches musician application software 8M stored on musician smartphone 5 as a means of resolving the problem. In this case, musician smartphone 5 transmits a disclosure request signal to cloud server device 1, along with at least musician identification signals (membership number, ID, password, memorandum serial number), requesting disclosure of either or both of the negotiation signal providing historical information from the performance negotiation stage and the memorandum information signal providing a signed memorandum, both of which are stored in database 4 of cloud server device 1. In response to receiving the disclosure request signal, cloud server device 1 extracts from database 4 either or both of the negotiation signal providing historical information from the performance negotiation stage and the memorandum information signal, which are associated with the musician identification signal and the event venue identification signal, and transmits them to musician smartphone 5 via router 2 and Internet 10. Through this transmission, musician smartphone 5 obtains the negotiation details providing historical information from the performance negotiation stage with event venue E, and / or the final memorandum signed by both parties. In order to resolve the issue, musician M will present his argument to event venue E, with whom he was matched, by presenting historical information (negotiation details) from the performance negotiation stage and / or a memorandum signed and dated by both parties as evidence of the contents of the performance contract.

[0063] On the other hand, there may be cases where Musician M defaults on his obligation, such as failing to show up on the contracted date and time, resulting in damages to Event Venue E. In such cases, as an exceptional information processing or exceptional measure, Music Management System 100 allows Event Venue E to retain evidence data in the system to resolve disputes arising from the performance contract. Specifically, Event Venue Tablet Terminal 6 obtains Event Venue Application Software 8E from External Server 7 via the Internet 10, launches Event Venue Application Software 8E, and Event Venue E touches the "Disclosure Request" button (not shown) on Display 6D in response to a signal sent from Server 3. In response to this touch, Server 3 sends a signal to Event Venue Tablet Terminal 6, displaying a screen listing pre-defined examples of reasons why Event Venue E made a disclosure request. The event venue E selects the relevant cause (e.g., musician M's default) from among multiple causes displayed on a screen (not shown) on the display 6D in response to the signal by touching or other operations, and the event venue tablet terminal 6 transmits a signal indicating the selected cause to the server 3. In response to receiving and analyzing this signal, if the server 3 determines that the disclosure request from the event venue E is legitimate and accepts the request, it transmits, as an exceptional measure, a signal to the event venue tablet terminal 6 that displays a screen displaying input fields for the musician membership number, etc. and the event venue membership number, etc. (including ID, password, and relevant memorandum serial number) (at least the event venue membership number, etc.) and a "Disclosure Request" button. Upon receiving the signal, the event venue tablet terminal 6 transmits the disclosure request signal to the server 3 along with the musician-specific signal and the event venue-specific signal (including ID, password, and relevant memorandum serial number) (at least the event venue-specific signal).In this case, depending on the type of data or information that the disclosure request signal requests or commands as evidence data, the server 3 will transmit either one or both of the following signals, extracted from the database 4: a negotiation signal providing each piece of historical information from the performance negotiation stage and a memorandum information signal providing a signed memorandum, to the event venue tablet terminal 6 via the router 2 and the Internet 10. As a result, event venue E obtains each piece of historical information from the performance negotiation stage and / or the signed memorandum as evidence of its claim.

[0064] In addition, the cloud server device 1 also provides a service of sending a memorandum information signal providing the reissued memorandum to the musician's smartphone 5 and / or the event venue's tablet terminal 6, either for a fee or free of charge, in response to a request for a reissue of the memorandum from the musician M and / or the event venue E.

[0065] (Embodiment 2) In this embodiment, contrary to the first embodiment, a case is described in which matching processing is performed for each musician M from the event venue E side in the music management system 100. Therefore, the disclosures of Figures 1, 2, 3, 6, 7, and 8, as well as the descriptions in the first embodiment corresponding to those figures, are incorporated into this embodiment. The main differences from the first embodiment are in the information processing for matching registration and execution, and the flow of main electrical signals between the components 4, 5, 6, and 7 of this system 100.

[0066] 9 is a diagram showing the process by which the event venue tablet terminal 6 selects and registers a musician M with whom it wishes to perform a match from the registration information of multiple musicians already registered, and then executes the match. Also, FIG. 10 is a diagram showing the transmission and reception of main electrical signals within the music management system 100 in this embodiment.

[0067] B-1: Matching process from the event venue E side, such as store owners Summary: The event venue computer runs the event venue application software obtained via the Internet. After the application is run, the event venue computer transmits a matching signal to the cloud server device via the Internet based on the on-screen display of the musician registration information signal transmitted from the cloud server device to the event venue computer via the Internet. The "matching signal" here refers to a signal from the event venue (including the Internet distribution site) indicating the intention to match the desired musician with the desired musician to perform, present, or distribute music at the event venue. The details of this procedure are as follows. In the following description, the term "event venue" includes the Internet distribution site.

[0068] Details: First, in response to an operation on the event venue E side, the event venue tablet terminal 6 downloads and installs the event venue application software 8E from the external server 7 in FIG. 1 via the Internet 10, thereby acquiring the application software 8E. Instead of downloading the event venue application software 8E from the external server 7, the server 3 may be provided with a function for storing the application software 8E within the server 3 and downloading the application software 8E directly from the server 3. The event venue E side may also acquire the event venue application software 8E from the external server 7 via the Internet 10 in advance, prior to carrying out the registration procedure for the "event venue registration information" described above. The event venue tablet terminal 6 then operates the event venue application software 8E based on an operation on the event venue E side. In response to the operation of this app 8E, the matching site on the server 3 (see Figures 1 and 10) sends a signal to the event venue tablet terminal 6 via the Internet 10, which sequentially displays a matching screen as the procedure progresses, allowing the event venue E to select the musician M they would like to have perform, show, or distribute music at the venue, based on the "musician registration information" stored in the database 4.As in the first embodiment, instead of using the native app 8E, the event venue tablet terminal 6 may (1) actively proceed through each process after the matching process by using a "web app (web application)," or (2) actively proceed through each process after the matching process by using a "hybrid app (hybrid application)," or (3) actively proceed through each process after the matching process by using "PWA (Progressive Web Apps)," or (4) actively proceed through each process after the matching process by receiving an environment (platform provision) such as a matching site on the server 3 of the cloud server device 1, or (5) actively proceed through each process after the matching process by using "TWA (Trusted Web Activities)." Here, each of the above-mentioned native app, web app, hybrid app, PWA, TWA, and various apps and devices providing platforms will be defined and referred to as a "cloud server connection means."

[0069] First, as shown in Figure 9(a), in response to the operation of the musician application software 8M, the matching site on the server 3 sends a signal to the event venue tablet terminal 6, providing an image for the event venue E to select the genre of musician M, and the resulting screen is displayed on the display 6D. In response to the display of this screen, the event venue E selects at least one genre that they would like musician M to perform at the venue, and upon completion of the selection, selects or operates the "Pick Up" button on the screen by touching or otherwise operating it. In response to this operation, the event venue tablet terminal 6 transmits a signal providing all of the genres selected by the event venue E to the matching site on the server 3 via the Internet 10.

[0070] Next, as shown in FIG. 9(b), the matching site on the server 3 sends a signal to the event venue tablet terminal 6 to provide an image displaying information or data about the arrangements of musicians M belonging to all genres selected by the event venue E in a sequential manner in a row based on the "musician registration information" in the database 4, and the image is displayed on the display 6D. In response to this display, the event venue E selects the arrangement of at least one musician M and selects or operates the "Pickup" button on the screen by touching or otherwise. In response to this operation, the event venue tablet terminal 6 transmits a signal providing information or data about the arrangements of all musicians M selected by the event venue E to the matching site on the server 3 via the Internet 10. If the event venue E wishes the screen on the display 6D shown in FIG. 9(b) to be displayed again the next time a matching operation is performed, the event venue E selects or operates the "Save" button on the screen of the display 6D by touching or otherwise.

[0071] Next, as shown in FIG. 9(c), the matching site on the server 3 transmits a signal to the event venue tablet terminal 6 to display a listing page screen showing all musicians M belonging to the selected lineup based on the "musician registration information" in the database 4, and the screen is displayed on the display 6D. In response to this display, the event venue E selects one or more of the musicians M on the screen and selects or operates the "Pickup" button by touching or otherwise operating it. The event venue tablet terminal 6 then transmits a signal indicating the selected musician M to the matching site on the server 3. In response to receiving this signal, the matching site on the server 3 transmits a signal via the Internet 10 to the event venue tablet terminal 6 to display a screen showing all of the registration information for the selected musician M, as shown in FIG. 9(d), based on the "musician registration information" in the database 4, and the screen is displayed on the display 6D. Here, the event venue E selects or operates the "video, still image, audio" button on the screen by touching or otherwise operating it. In response to the signal transmitted from the event venue tablet terminal 6, the My Page website for musician M on the server 3 is linked. That is, if the My Page website on the server 3 determines that video, still images, and audio data related to the selected musician M is pre-stored within the My Page, it transmits a signal to the event venue tablet terminal 6 providing video, still images, and audio data related to the performance or performance of the selected musician M. This transmission results in the video, still images, and audio data related to the performance or performance of the selected musician M being displayed on the display 6D of the event venue tablet terminal 6. On the other hand, if the My Page website on the server 3 determines that video, still images, and audio data related to the performance or performance of the selected musician M is not pre-stored, no signal providing video, still images, and audio data is transmitted to the event venue tablet terminal 6, and the video, still images, and audio data related to the performance or performance of the selected musician M is not displayed on the display 6D. Alternatively, a "none" screen may be displayed.If the event venue E determines that it does not wish to be matched with musician M based on the registered musician information displayed on the screen of display 6D, it selects or operates the "Back" button displayed on the screen of display 6D by touching or otherwise selecting or operating the "Back" button. In response to this selection or operation, the matching site of server 3 receives a signal transmitted from event venue tablet terminal 6 and again transmits a signal displaying the screen shown in FIG. 9(c) to event venue tablet terminal 6 via Internet 10, and this screen is displayed on display 6D. Then, event venue E selects one of the other musicians M that it would like to be matched with from the redisplayed matching screen shown in FIG. 9(c) and selects or operates the "Pickup" button by touching or otherwise selecting or operating the "Pickup" button. A similar procedure is then executed by transmitting and receiving signals between event venue tablet terminal 6 and the matching site of server 3. On the other hand, if the event venue E determines that it does wish to be matched with musician M based on the registered musician information displayed on the screen of display 6D, it selects or operates the "Matching Registration" button on the screen of display 6D by touching or otherwise selecting the "Matching Registration" button. The matching site of the server 3, which receives the signal transmitted from the event venue tablet terminal 6 in response to such a selection operation, such as touching, transmits a signal to the event venue tablet terminal 6 via the Internet 10 to display the "matching registration" screen shown in FIG. 9(e), and the screen is displayed on the display 6D. On this matching registration screen, as shown in FIG. 9(e), a check mark indicating the request is displayed in the column for musician M, with whom the event venue E wishes to be matched. In this "matching registration," when the event venue E selects the "Save to My Page" button on the screen of FIG. 9(e) by touching or other operation, the matching site of the server 3, in response to such a selection operation, saves data indicating the musician with whom the event venue E wishes to be matched, to the "My Page site" for the event venue E.The matching site of the server 3 then transmits a signal displaying an image of "Saving to My Page Completed" to the event venue tablet terminal 6 via the Internet 10, and the image "Saving to My Page Completed" is displayed on the display 6D of the event venue tablet terminal 6 (see FIG. 9(f)). At the same time, the matching site of the server 3 instructs the event venue tablet terminal 6 to display a "Done" mark instead of a "Check" mark in the right column of the column for musician M, the desired match partner, on its display 6D (see FIG. 9(f)). If the event venue E wishes to further match with other musicians M, the event venue E selects the "Back" button on the screen of the display 6D by touching or other operation. In response to this selection operation, such as touching, signals are transmitted and received between the event venue tablet terminal 6 and the matching site of the server 3, and the screen shown in FIG. 9(c) is redisplayed on the display 6D. At this time, for musicians M who have already been registered for matching, a "Completed" mark appears in the column 6B to the right of that musician M's column, as shown in Figure 9(c). The aforementioned process and signal exchange then continues. Finally, when all musicians M with whom the event venue E wishes to match have been determined, the event venue E selects or operates the "Matching" button on the screen shown in Figure 9(e) by touching or otherwise. At this time, the event venue E can avoid matching by unchecking the column for the musician M registered for matching. Furthermore, the registration information for the desired musician M can be saved on the My Page website for the event venue E. In response to this selection or operation, the event venue tablet terminal 6 transmits a "matching signal" via the Internet 10 to the matching site on the server 3, indicating the event venue E's intention to match with each musician M selected by the event venue E from among the musicians M shown in Figure 9(c) as a matched partner.

[0072] B-2: Transmission of matching transmission signal The matching site of the server 3 receives the above-mentioned "matching signal" from the event venue tablet terminal 6 and transmits a matching transmission signal to the musician smartphone 5 of each musician M who has been matched via the Internet 10. In other words, in response to receiving the above-mentioned matching signal, the matching site of the server 3 transmits a "matching transmission signal" indicating the intention to match from the event venue E and providing the URL of the matching site on the server 3 as an e-mail signal to the musician smartphone 5 of each musician M who has been matched.

[0073] B-3: Matching answers of each musician M Upon receiving the matching transmission signal (email signal), the musician's smartphone 5 of each musician M accesses the matching site of the server 3 based on the URL of the matching site of the server 3 in response to an operation, such as a touch, by the musician M after viewing the contents of the email. In response to this access, a signal transmitted from the matching site of the server 3 causes a predetermined screen to be displayed on the display 5D of the musician's smartphone 5. The "Details" section at the top of this predetermined screen displays all of the event venue registration information (including moving images, still images, etc.) of the event venue E with which the musician M is seeking a match. The center of this predetermined screen displays "Matching Response Buttons" (YES, NO) for the musician M, who has been selected as a matched partner, to indicate whether or not he or she will accept the matching intention from the event venue E based on the event venue registration information. Furthermore, the "Details" section at the bottom of this predetermined screen displays the reason for the musician M's "NO" decision. The musician M may also be configured to be able to select a preset comment for the "NO" decision.

[0074] Here, based on the event venue registration information, musician M, who has been designated as a matching partner, decides that he or she is willing to accept the matching intention from event venue E and enter into contract negotiations for a musical performance / show with event venue E. In this case, musician M selects or operates the "YES" button on the screen of display 5D by touching or otherwise selecting or operating it, and in response to this selection or operation by touching or otherwise selecting or operating it, musician's smartphone 5 transmits a matching response signal indicating musician M's intention to accept the matching intention from event venue E to the matching site of server 3 via Internet 10 and router 2. On the other hand, if musician M decides not to accept the matching intention from event venue E, musician M selects or operates the "NO" button on the screen of display 5D by touching or otherwise selecting or operating it, and musician's smartphone 5 transmits a matching response signal indicating the event venue's intention to not accept the matching intention from event venue E to the matching site of server 3 via Internet 10 and router 2. At that time, the musician's smartphone 5 transmits a signal indicating the reason for rejecting the expression of intent to match from the event venue E to the matching site of the server 3 together with the above-mentioned matching response signal. Alternatively, the musician's smartphone 5 may simply transmit only a matching response signal meaning "NO" to the matching site of the server 3 without indicating the above-mentioned reason for rejection. Alternatively, the musician's smartphone 5 may not transmit any response signal. Also, it may be configured so that a preset comment for the case of "NO" is selected.

[0075] C-1-1: When the matching partner musician M answers "YES" In response to receiving the matching response signal indicating a "YES" response, the matching site of the server 3 transmits, as an email signal, the "YES" response signal and a conference room access signal required to access the conference room site, which is a location where the event venue E and the other party's musician M can negotiate for performance with each other via the Internet 10 on the "conference room" site, a shared screen on the server 3. That is, the matching site of the server 3 transmits, via the Internet 10, to the email address of the event venue tablet terminal 6, a conference room access signal indicating the "YES" response and a conference room access signal (email signal) that provides the URL of the conference room site and key information (key information) common to the event venue E and the other party's musician M for entering the conference room site. In addition, the matching site of the server 3 transmits, via the Internet 10, to the email address of the musician smartphone 5 of the corresponding musician M, a conference room access signal (email signal) that provides the URL of the conference room site and key information (key information) common to the event venue E and the other party's musician M for entering the conference room site.

[0076] C-1-2: When the matching partner musician M answers "NO" In response to receiving a matching response signal indicating a "NO" answer from musician M, the matching site of server 3 sends a signal indicating that musician M's intention is "NO" and a signal indicating the reason as an e-mail signal to the e-mail address of the event venue tablet terminal 6. Alternatively, the matching site of server 3 may simply send a signal indicating that musician M's intention is "NO" to the e-mail address of the event venue tablet terminal 6 without providing a reason. Alternatively, the matching site of server 3 may not send any e-mail signal. Alternatively, it may be configured so that a preset comment for the "NO" case is selected.

[0077] The subsequent series of procedures, namely, "C-2: Access to the conference room from the event venue E," "C-3: Access to the conference room from the other party, musician M," "C-4: Negotiations between the event venue E and musician M in the conference room," "C-5: Storing a negotiation signal in database 4 that provides historical information (negotiation details) of the performance negotiations," "C-6: Storing a memorandum information signal in database 4," and "D: Disclosure requests from musician M as a rule and disclosure requests from event venue E as an exception," are as described in the first embodiment, and the corresponding descriptions in the first embodiment are incorporated herein by reference. Even in this embodiment, in which performance negotiations are conducted in response to a matching request from event venue E, amateur musician M remains in a weak position in relation to the other party, event venue E. Therefore, in this system 100, the electronic computer that can send a disclosure request for the "negotiation signal / memorandum" to server 3 is, in principle, musician M's musician smartphone 5.

[0078] (Advantages of Music Management System 100) (1) The system 100 described in each of the first and second embodiments can dramatically increase the opportunities for amateur musicians, who generally have relatively few opportunities to perform, play, or receive major distribution, and who are unfamiliar with self-promotion and contract negotiations. As a result, the system 100 provides each musician with numerous opportunities (places for performance) to present music in their preferred genre in the venue of their choice.

[0079] (2) Since various information such as the number of appearances and reputation of musicians who have actually performed, performed, or made major distribution using this system 100 can be obtained and managed by server 3, this system 100 can function like an audition, in that it can identify promising musicians from among musicians who have been given a relatively large number of opportunities to perform, perform, and release (including distribution, etc.).

[0080] (3) Even if some kind of dispute arises between the parties during or after the performance of a performance contract concluded through this system 100, an amateur musician who is in a weaker position due to reasons such as inexperience in performance negotiations and dispute resolution negotiations can: 1) retain a record of each exchange between the parties during the performance negotiation stage and / or the final approval of both parties through this system 100 on the server. Furthermore, the musician can obtain as evidence 2) data representing the memorandum (= contract) "signed by both parties" in the broad sense described above by requesting disclosure from this system 100. Therefore, the musician in a weaker position can present this data as evidence to the event venue and negotiate to resolve the dispute, and can fully expect to advance the dispute resolution negotiations to his or her advantage. Furthermore, contractual disputes may arise between the parties due to unclear contractual provisions in the performance contract concluded between the parties. In this regard, as described above, in the present system 100, the parties can create, as an electrical signal, data on the cloud server device 1 that provides "documentary evidence equivalent to a contract," such as a "contract" with or without a seal or a "confirmation letter" with or without a seal, which serves to prove the "formation and content of the contract," and record and store the electrical signal of the data in the database 4. As described above, the digital data of the final and broadly signed memorandum (contract) provided by the memorandum information signal may not contain data on the seals of both parties, or may contain data on the seals of both parties using various sealing technologies, such as electronic seals. Furthermore, the creation and storage of digital data of memorandums (contracts) "signed by both parties" and "without seals," or "signed by both parties" and "with seals," can be performed using various terminal devices (smartphones, tablet devices, PCs, etc.) connected to communication infrastructure lines such as the Internet.), both parties electronically sign or electronically sign and affix their electronic seals using electronic tools such as electronic pens or electronic pens and electronic seals, respectively, on the screen of a mobile device such as a cloud. This digital data memorandum, which is a contract, can be generated on the cloud and stored in Database 4. Additionally, with regard to the creation and storage of digital data of memorandums (contracts) "signed by both parties" in the broad sense described above on the cloud, various authentication technologies such as biometric authentication technology can be utilized in conjunction with AI, etc. to create and store digital data of the agreement (digital legal evidence that proves the formation of the contract and the specific contents of the contract) on the cloud, linking, for example, video or audio recordings of a scene such as "Party XX's voice approves contract document number XX," biometric authentication data of the parties themselves, and detailed data in the memorandum. In other words, by utilizing various biometric authentication technologies such as voice authentication (voice voiceprint), fingerprint / palm print authentication, finger vein authentication, facial authentication, iris (rainbow) authentication, and ear acoustic authentication, as well as various technologies such as XR, ultra-high definition video, holograms (3D holograms, avatars (characters that act as your other self), etc.), and AI, all of the legal evidence data made up of the biometric authentication data of each party (voice recognition, facial recognition, etc.) linked to the agreement and contract settlement information data between the parties (recorded video, recorded audio, images, text, etc.) and data on relevant documents such as memorandums (contracts), confirmation letters and memos described below, and other "legal evidence documents equivalent to contracts," can be generated on the cloud as memorandum information signal data that has been "signed by both parties" in the broad sense, and saved and recorded in Database 4. Therefore, the present system 100 can prevent the occurrence of such problems and can effectively and accurately resolve existing problems. For example, consider a case in which some kind of trouble arises between the parties to the above-mentioned contract during business development due to a breakdown in the relationship of trust between the parties. In this case, one party wishing to favorably negotiate a settlement of the trouble can store a history of each interaction between the parties during the negotiation phase and / or the final approval of both parties by the present system 100 on a server. Furthermore, by requesting disclosure of the data of the memorandum of agreement (contract) signed by both parties in a broad sense, the party can obtain it as evidence proving the formation of the contract and its contents. Therefore, the party can present this acquired data to the other party as evidence of the contract and negotiate to resolve the trouble, which can be expected to advance the negotiation to its own advantage.

[0081] (4) On the other hand, an event venue that plans or intends to hold a certain type of event in a certain area to revitalize the area can use this system 100 to gather together many musicians from various locations who are compatible with or support the purpose of the event and hold a music event as one of the events. Therefore, this system 100 can also be used as a means of "regional revitalization," "regional vitalization," or "regional creation."

[0082] (Variation) (1) Cloud server device 1 translation function: The cloud server device 1 may be equipped with a multilingual function that can convert and translate the screens of mobile devices or computers, such as smartphones for musicians and tablets for event venues, into various foreign languages, such as English and Chinese. For example, a button display indicating a foreign language, such as "English" or "Chinese," may be displayed at the top of the screen provided by each server 3 site on the display of each mobile device. When an operator operates such a button display by touching or otherwise operating such a button, all text on the entire screen of each mobile device is converted and displayed in the corresponding foreign language. In this case, through the aforementioned matching function of the present system 100, Japanese and foreign musicians can collaborate on musical event appearances, increasing opportunities for foreign musicians to perform at Japanese event venues, and vice versa, increasing opportunities for Japanese musicians to perform at event venues overseas. Participation by inbound tourists from overseas is also expected, which is expected to have an effect on revitalizing local and regional economies in line with the government's tourism DMO policies. It can be used to approach inbound tourists, promote visits to local areas, and as a means of "regional revitalization," "regional vitalization," or "regional creation."

[0083] (2) Application to regional revitalization: In the case of holding an event venue for "regional revitalization" in a specific area, free or discount coupons may be made available for download to the general public from the event venue's computers (such as the server of this system or an external server) to promote the event and revitalize the area.

[0084] (3) Application to matching amateur artists (including semi-professional artists) in various fields with event venues: In the first and second embodiments, the music management system 100 is described as having a function of matching amateur musicians with event venues. However, the aforementioned services provided by the music management system 100 according to the first and second embodiments, as well as the various functions, such as matching, possessed by the music management system 100, can also be applied to matching amateur artists belonging to fields other than music with event venues, and similar advantages, effects, and problem-solving can be obtained. In this sense, an "artist management system" that realizes the aforementioned matching function, the content certification function at each stage of contract negotiation, and the contract establishment certification function after contract signing should be considered a management system in a broad sense, including the music management system 100. Therefore, the relevant descriptions of the music management system 100 described in the first and second embodiments are used to describe the configuration, operation, functions, and so forth of an "artist management system" related to matching artists belonging to fields other than musicians with event venues. In the present invention, the meaning of the term "artist" or "artist" who seeks a venue to showcase his or her artistic abilities should be interpreted as broadly as possible. Examples of amateur artists who wish to be matched with event venues include painters (illustrators), cartoonists, film directors, sculptors, ceramic artists, photographers, street performers, music and stage actors, dancers, ballerinas, entertainers, magicians, comedians, advertising creators, designers, etc. The meaning of "amateur" here is defined synonymously with the meaning described in the first and second embodiments. In this modification, for example, a "musician's electronic computer" is generalized to an "artist's electronic computer," a "musician registration information signal" is generalized to an "artist registration information signal," a "musician identification signal" is generalized to an "artist identification signal," and "musician application software" is generalized to an "artist application software." Furthermore, "musician" is generally referred to as "artist."Furthermore, "performance negotiations" is a generalized term that refers to negotiations (a series of activities for concluding a contract) between an artist and an event venue to receive an event venue (including online distribution) for the artist to present his / her artistic abilities at the event venue. Of course, the "performance negotiations" also include performance negotiations (including negotiations for performance, performance, announcement, distribution, etc.) between musician M and event venue E.

[0085] In the present invention, the terms "performance, performance, presentation (including distribution, etc.)" and the like described in the first and second embodiments are generalized to "an artist's presentation of his or her artistic abilities." Furthermore, the "artist management system" of the present invention can be applied to professional artists who have the same problems as those described above, and the advantages described above can be obtained in this case as well. Furthermore, the "artist management system" of the present invention can also be applied to professional artists seeking a "place to present their artistic abilities," regardless of whether they have the problems described above. Even in this case, each professional artist can obtain the several advantages described above, such as being provided with numerous opportunities (presentation venues) to present art (music, etc.) in their preferred genres in the venues of their choice.

[0086] <Supplementary information> Regarding the methods and technologies of information transmission or communication during the aforementioned matching, negotiation, memorandum (contract) drafting, and contract conclusion processes, they may include: 1) the transmission or communication of written data (text: characters, figures, diagrams, etc.) or oral or dictated data by both or one of the parties; 2) the transmission or communication of audio, video, or image data by both or one of the parties; or 3) the transmission or communication of information using various technologies such as ultra-high-definition video of 8K or higher, high-capacity high-speed communication lines of 5G / 6G or higher, holograms (including 3D holograms and avatars), AI, XR (including VR, AR, MR, etc.), communication of information obtained through the five human senses (the "five senses" refers to all human senses, including sight, hearing, touch, smell, and taste), and quantum computers. The cloud server device 1 may use AI or other technologies to process information transmitted orally or dictated by both parties or one of the parties using audio, video, or image data, and then create and store the signals of the written, visualized, and charted data as signals of a memorandum (contract) showing the data under negotiation and the content of the concluded contract. For example, consider a case where one party wishes to use the present system 100 to negotiate and conclude a contract with the virtualized first party using technologies such as 8K or higher ultra-high-definition video, including 3D video, holograms (including 3D holograms, avatars, etc.), XR, and AI over an ultra-high-speed internet connection of 5G and / or 6G or higher, and the other party wishes to negotiate and conclude a contract with the virtualized first party using 8K or higher ultra-high-definition video or 3D hologram (video) image (including avatars, etc.). At this time, based on the data of the negotiation contents and memorandum contents between the two parties, both of which serve as legal evidence data and are created and stored as signals by both parties on the cloud, the two parties can more reliably proceed with and develop the negotiations and conclusion of contracts such as performance contracts in an environment filled with a sense of reality, with the content of the established and concluded contract clearly clarified as a background.Data on the contents of negotiations and memorandums (contract contents) concluded between the parties using such advanced technologies can also be clearly created as electronic signals on the cloud and securely stored in the database before any problems arise, using the present system 100. As described above, with regard to the creation and storage of digital data of memorandums (contracts) that are "signed by both parties" and "unsealed" in the broad sense, or "signed by both parties" and "sealed" in the broad sense, memorandum information signals that provide a "memorandum," a contract in the form of digital data, formed by both parties using electronic tool devices such as electronic pens or electronic tool devices such as electronic pens and electronic seals on the screens of various terminal devices (smartphones, tablet devices, PCs, etc.) connected to communication infrastructure lines such as the Internet, can be generated on the cloud and stored in database 4. Alternatively, with regard to the creation and storage on the cloud of digital data of a memorandum (contract) that has been "signed by both parties" in the broad sense, various authentication technologies such as biometric authentication technology can be utilized in conjunction with AI, etc. to create and store on the cloud digital data of the agreement (digital data of legal evidence that serves as proof of the formation of the contract and the specific contents of the contract) that provides a memorandum (contract) that has been "signed by both parties" in the broad sense, by linking together video or audio recordings of a scene such as "The contract document number XX has been approved by the voice of Party XX," the biometric authentication data of the parties themselves, and detailed data within the memorandum. That is, by utilizing various biometric authentication technologies such as voice authentication (voice print), fingerprint / palm print authentication, finger vein authentication, face authentication, iris authentication, and ear acoustic authentication, as well as technologies such as XR, ultra-high definition video of 8K or more, holograms (3D holograms, avatars (characters that act as your alter ego), etc.), and AI, the biometric authentication data of each party (voice recognition, face recognition, etc.) is converted into agreements and contract settlement information data between the parties (recorded video, recorded audio, images, text, etc.).All legal evidence data, which is linked to data on relevant documents such as "legal evidence documents equivalent to contracts," such as memoranda (contracts), confirmation letters, and memos (described below), may be generated on the cloud and recorded and stored in a database as "memorandum information signals" that provide memoranda (contracts) that have been "signed by both parties" in the broad sense.

[0087] (Points to note) The term "memorandum" in the disclosure of the first and second embodiments of the present invention is used to refer to a "contract" as a "document certifying the formation of a contract" (Kojien, 7th edition). Here, the "memorandum" is a legal document indicating the "contract formation and contract contents" that has been "signed by both parties" in the broad sense and is digitized by being created and stored on the cloud server device 1. However, in the present invention, the term or concept of "memorandum" is defined and understood in a broad sense to include not only the above-mentioned "contract," but also "memorandum" as a "document or memo to be written down so as not to forget" (Kojien, 7th edition), or various formal terms for documents such as so-called "confirmation," "agreement," "contract," or "exchange memo." In other words, the term / concept "memorandum" (= legal document) is a term / concept that includes a) the above-mentioned "contract," and also b) "documentary evidence equivalent to a contract (with or without a seal)" that serves to prove the contents of the contract, such as the above-mentioned "memorandum" or "confirmation letter" as a memo. Therefore, a "memorandum information signal" that provides data on the "memorandum" as a "contract" that indicates the "formation of the contract and the contents of the contract" finally concluded through negotiations between the parties is created on the cloud server 3, stored in the database 4, and disclosed by the server 3 in response to a disclosure request. Alternatively, a "memorandum information signal" that provides data (first data) on the above-mentioned "documentary evidence equivalent to a contract," such as the above-mentioned "memorandum" or "confirmation letter," as a memo may be created on the server 3, stored in the database 4, and disclosed by the server 3 in response to a disclosure request, as evidence (memorandum) that indicates the "formation of the contract and the contents of the contract" finally concluded through negotiations between the parties. Alternatively, the cloud server device 1 may create both the data of the "memorandum" as the "contract" and the data of the "documentary evidence equivalent to the contract" (first data) on the cloud, store and record the second data consisting of both data in its database 4, and disclose both the data of the "memorandum" as the "contract" and the data of the "documentary evidence equivalent to the contract" in response to a disclosure request from one or both of the contracting parties.

[0088] (Addendum) Introduction of (quantum-resistant) blockchain technology The cloud server device 1 in the first and second embodiments and modifications described above and each of a plurality of node computers (not shown) separate from the cloud server device 1 may be connected to one another in a distributed manner via the Internet 10 in a peer-to-peer (P2P) manner to construct or form a "blockchain." Here, the "peer-to-peer method" or "P2P network" refers to a method in which a plurality of computers distributed over a network such as the Internet exchange data on an equal basis. In particular, in this example, a data structure of a blockchain equipped with or implementing a "smart contract" function may be constructed. Basic information on "blockchain" is disclosed, for example, in the aforementioned Non-Patent Document 1.

[0089] In this example, the cloud server device 1 itself is one of the "nodes" (computers) that make up the blockchain, and also serves as a "minor node," which creates "blocks." The introduction of blockchain technology offers the advantage of effectively preventing tampering with various data stored in the database 4 of the cloud server device 1, such as "registration information," "history information," and "memorandum information." The cloud server device 1 and the multiple node computers that make up the blockchain build or form an autonomous, decentralized data structure that is difficult to tamper with and easy to verify via the Internet 10. To build or form such a data structure, the functionality of a "smart contract," a program that shares the same fundamental concept as blockchain and runs on the blockchain, can be incorporated into the blockchain infrastructure. This eliminates the inconvenience and inefficiency of processes such as stamping, and automatically creates and concludes "transactions" such as negotiation history information and memorandums of contracts, which are then recorded and stored in blocks. This builds or forms an autonomous, decentralized data structure that is difficult to tamper with and easy to verify. Regarding "smart contracts" on a blockchain platform, 1) smart contracts on a public blockchain such as Ethereum (which has smart contract functionality built in), 2) smart contracts on a consortium blockchain, or 3) smart contracts on a private blockchain may be used. Note that a distinctive feature of Ethereum (1) above is that it has a program execution function linked to the blockchain built in, and application programs on Ethereum are called "smart contracts" or "distributed applications (DApps)." The advantage of public blockchains is that they allow users to use a reliable data infrastructure as if it were a public service.Furthermore, the name of a "smart contract" on a blockchain platform varies depending on the blockchain platform. For example, on Ethereum, as mentioned above, a "smart contract" is simply called a "smart contract."

[0090] An example of a data structure constructed by a blockchain in the first and second embodiments is as follows: 1) Each piece of data (transaction data) of "registered information" stored and saved in the database 4 of the cloud server device 1 is stored in a block (unit of data) as a "transaction" encrypted by a hash function using a nonce value as a parameter, together with the hash value and nonce value of the immediately preceding block connected to that block. Then, in each subsequent block connected to that block like a chain, the encrypted data (transaction data) related to that "registered information" is stored as a "transaction" in chronological order, together with the hash value and nonce value of the immediately preceding block. This generates a blockchain-based state of the "registered information." Similarly, 2) each "history item (negotiation content) information" in the negotiation process between the parties that is stored and preserved in database 4 is stored in a single block (unit of data) as a "transaction" encrypted using a hash function with a nonce value as a parameter, along with the hash value and nonce value of the immediately preceding block connected to that block. At the same time, in each subsequent block connected to that block like a chain, the encrypted data (transaction data) related to each "history item (negotiation content) information" is stored as a "transaction" in chronological order, along with the hash value and nonce value of the immediately preceding block. This creates a blockchain-like state of each "history item (negotiation content) information" in the negotiation process between the parties. Furthermore, 3) the "memorandum information" finally established through the negotiation process between the parties is also stored in that single block as a "transaction" encrypted using a hash function with a nonce value as a parameter, along with the hash value and nonce value of the immediately preceding block connected to that single block (unit of data). At the same time, in each of the subsequent blocks that are connected to the block in a chain, the encrypted data (transaction data) related to the "memorandum information" is stored as a "transaction" along with the hash value and nonce value of the previous block, in a chronologically synchronized sequence.This creates a blockchain-based version of the "memorandum information" finally established through the negotiation process between the parties. Transaction data stored in other databases, such as "My Page," is also stored in a blockchain-based format. Blockchains encrypt and irreversibly manage and store transaction data across distributed, autonomous nodes (computers), creating a data structure that makes transaction data tamper-resistant. Smart contract functions and services on public blockchain platforms, such as Ethereum, may also be utilized. Alternatively, instead of using Ethereum, smart contracts on consortium blockchains or private blockchains may be used as smart contracts on blockchain platforms.

[0091] However, with the advancement of quantum computer technology, there is a possibility that blockchain encryption may be broken by a quantum computer. One countermeasure for this is to provide "quantum resistance" to the aforementioned blockchain formed between the cloud server device 1 (Figure 1) and the above-mentioned multiple node computers. An example of a quantum-resistant blockchain using quantum-resistant encryption technology is the QRL (Quantum Resistant Ledger) blockchain. By adopting and building such a quantum-resistant blockchain, it becomes possible to prevent the encryption in the blockchain from being broken by a quantum computer, thereby dramatically increasing the resistance to tampering of transaction data such as "memorandum information."

[0092] (Addendum) Although the embodiments of the present invention have been disclosed and described in detail above, the above description is merely an example of applicable aspects of the present invention, and the present invention is not limited thereto. In other words, various modifications and / or variations to the described aspects can be considered within the scope of the present invention. [Industrial Applicability]
