[Diagram 2] 2 is a functional block diagram showing the server device of FIG. 1. [Diagram 3] 2 is a functional block diagram showing the user terminal of FIG. 1. [Figure 4] FIG. 4 is a flow diagram showing an example of an information processing method according to the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] A preferred embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are denoted by the same reference numerals to avoid repetitive description. Note that the embodiments described below do not unduly limit the contents of the present disclosure described in the claims. In addition, not all of the components shown in the embodiments are necessarily essential components of the present disclosure.

[0013] <Configuration> FIG. 1 is a block diagram showing an information processing system according to an embodiment of the present invention. The information processing system 1 (hereinafter also referred to as "the system") includes a server device 100 as a management server that manages information on NFTs related to membership rights, usage rights, or reservation rights for real estate such as accommodation facilities, a user terminal 200 used by a user who is a user of a service using the system 1, an NFT market 300 in which NFTs are distributed, a blockchain 400 in which information (history, owner, etc.) of NFTs handled by the NFT market 300 is recorded, and an OTA service 500 capable of communicating with the server device 100. Note that the OTA service 500 is not a required configuration. Also, there may be a plurality of server devices 100, user terminals 200, NFT market 300, blockchain 400, and OTA service 500. Also, NFTs may be associated with trading objects other than usage rights and reservation rights for real estate.

[0014] The server device 100, the user terminal 200, the NFT market 300, and the blockchain 400 are each connected via a network. The network is configured with the Internet, an intranet, a wireless LAN (Local Area Network), a WAN (Wide Area Network), a fixed telephone line, a mobile phone line, or a combination of these. The server device 100 can also communicate with external systems, such as websites related to accommodation facilities and websites for travel, and can obtain various information, such as information related to facilities, from the external systems and transmit generated information.

[0015] <Server device> The server device 100 is managed by, for example, a system administrator (service provider). In this example, the user uses the user terminal 200 to transmit and receive information to and from the server device 100, but the server device 100 may be configured as a stand-alone device, and the server device itself may have an input function for direct operation by the user and an output function for checking the processing results.

[0016] The server device 100 is, for example, a computer (information processing device), and may be a general-purpose computer such as a workstation or a personal computer, or may be logically realized by cloud computing. In this embodiment, for convenience of explanation, one server device is illustrated, but the present invention is not limited to this and may be multiple servers.

[0017] Fig. 2 is a functional block diagram of the server device 100 in Fig. 1. The server device 100 includes a communication unit 110, a storage unit 120, and a control unit .

[0018] The communication unit 110 is a communication interface for communicating with the user terminal 200, the NFT market 300, the blockchain 400, etc. via a network, and communication is performed according to a communication protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol).

[0019] The storage unit 120 stores programs, input information, generated information, etc. for executing various control processes and various functions in the control unit 130, and is configured by one or any combination of RAM (Random Access Memory), ROM (Read Only Memory), flash memory, HDD (Hard Disk Drive), SSD (Solid State Drive), and other storages. It is preferable that the program is stored in a non-volatile storage medium among these storage media that configure the storage unit 120. In addition, the storage unit 120 has a user data storage unit 121 that stores various information related to users, an NFT data storage unit 122 that stores various information related to NFTs, etc. Furthermore, the storage unit 120 can store data communicated with the user terminal 200, the NFT market 300, and the blockchain 400, and can also store data generated by the control unit 130. Note that a database (not shown) that stores various information may be constructed outside the storage unit 120 or outside the server device 100.

[0020] The various types of information about users may include, for example, user ID, basic information about users (user's name, image of ID, address, telephone number, contact information such as email address, age, gender, etc.), user verification information (for example, user's face image, iris, retina, eye blood vessels, fingerprint, palm print, vein shape, biometric information, signature impression, etc.), NFT information currently owned or previously owned by each user, NFT information that each user has previously purchased or wishes to purchase (including purchase price, desired price, etc.), NFT information that has been sold or wishes to sell (including selling price, desired selling price), reservation information (including NFT purchase reservations and facility use reservations), payment information (payment history, credit card information, financial institution information, etc.), point information (amount of points available for use within this system, point history (used / earned), etc.), service usage history information (service usage history in this system), NFT wallet information, etc., but is not limited to this. NFT wallets are associated with addresses (wallet addresses) and private key information stored in the wallet, and are managed by the user terminal. For example, when each user uses the system for the first time or when making a request for a purchase, the user can register by inputting various information about the user. Identification information such as a user ID may be automatically assigned to each user by the control unit at the time of user registration, or information input by the user may be stored.

[0021] Various information related to NFTs include, for example, NFT image (image) information, facility information, owner information, price information, etc. Facility information may include, but is not limited to, facility identification information such as facility name and facility ID, facility address (location information), facility area, facility space information (number of rooms, location of each room, area, number of floors), available date and time, available period, available number of times, etc. Owner information may include, but is not limited to, owner identification information (wallet address or ID), name, image, address, telephone number, contact information such as email address, age, gender, etc. Price information may include, but is not limited to, a desired selling price (desired selling price) based on the owner's input, an estimated price (recommended price) calculated by the control unit, a transaction price in the past, a desired purchase price based on the input of a purchaser, a price related to a related facility associated based on a predetermined condition (including a desired selling price, a desired purchase price, an estimated price, and a past transaction price).

[0022] The information about the NFT may include information about whether the owner is listing the NFT as a saleable NFT or not. If the owner is listing the NFT as a saleable NFT, the information about the NFT may include information about the desired selling price.

[0023] Here, "real estate" associated with NFTs includes accommodation facilities, private lodging facilities, rental apartments, rental offices, rental spaces, etc. These include, for example, various buildings and land such as hotels, inns, rental villas, guesthouses, detached houses, condominiums, apartments, office buildings, warehouses, etc., regardless of the number of floors, structure, size, or area of ​​the building. In the following explanation, "facility" may be used to refer to the entire facility or a category of use of the facility (for example, individual rooms or spaces, etc.).

[0024] The control unit 130 controls the overall operation of the server device 100 by executing the programs stored in the storage unit 120, and is composed of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and the like.

[0025] The control unit 130 includes an input information receiving unit 131 that receives input information from the user terminal 200, an information acquisition unit 132 that acquires various information such as information related to NFTs, an information generation unit 133 that generates various information based on the acquired information, and an agent trading unit 134 that processes transactions such as bidding on the NFT market on behalf of the user.

[0026] The input information receiving unit 131 receives information input by a user via a web browser or application of the user terminal 200. For example, the input information receiving unit 131 receives information such as characters and numbers input by the user, and information on options selected by the user. The server device 100 stores and updates various information based on the input information.

[0027] The information acquisition unit 132 acquires information about one or more NFTs circulating on the network. For example, the information acquisition unit 132 acquires NFT information from either one or both of the NFT market 300 and the blockchain 400. The information acquisition unit 132 may acquire information from multiple NFT markets 300 and the blockchain 400, or may acquire information from other websites such as an OTA service 500. The OTA (Online Travel Agent) service 500 may be a service system of a travel agency that makes online hotel reservations, but may also be a website of a shopping mall or the like. The acquired various information is stored in the storage unit 120 and is presented to the user via a web browser or application of the user terminal 200. The NFT information includes, for example, NFT information that is being exhibited as an NFT that the owner wishes to sell, and non-exhibiting NFT information that is not being exhibited as an NFT that the owner wishes to sell. Here, in the NFT market 300 and the blockchain 400, not only information on NFTs that the owner of the NFT wishes to sell (listed), but also information on NFTs that the owner does not wish to sell (not listed) is disclosed. Therefore, the information acquisition unit 132 can also acquire information on NFTs that the owner of the NFT does not wish to sell. The NFT information includes metadata on the blockchain 400, etc. (for example, the blockchain and distributed storage). Metadata on the blockchain 400 related to the NFT has information on the NFT, such as an identifier, creation date and time, an owner address indicating the owner, and an object URL. The object URL is a URL indicating the location of the object whose owner the NFT certifies. The object whose owner the NFT certifies includes, for example, the right to use a facility for a specific period of time. The right to use a facility for a specific period of time may be one whose use date and time are disclosed, or one whose use date and time are not disclosed. If the use date and time are not disclosed, for example, after purchase, the use date and time are disclosed to the owner of the NFT by a reveal process or the like.

[0028] The information acquisition unit 132 acquires information about the rights associated with the NFT, that is, the rights information associated with the NFT, from at least one of the NFT market 300 and the blockchain 400. In addition, the information acquisition unit 132 acquires information such as whether the NFT is listed, the desired selling price if listed, whether there have been bids on the NFT, the number of bids, and bid prices (minimum bid price, maximum bid price).

[0029] The information generating unit 133 generates NFT-related information based on the acquired NFT information. The NFT-related information may be, for example, an estimated price of each NFT. The estimated price is calculated, for example, from the transaction price of a facility similar to the facility associated with the NFT. Specifically, the estimated price may be a value obtained by adding, subtracting, multiplying, or dividing a predetermined constant to the transaction price of the similar facility. A similar facility is set based on any one or a combination of predetermined parameters such as area, construction years, location (area), number of floors, and rank (evaluation value). Specifically, the area is about the same (the difference with the facility is within a certain range, etc.), the construction years are about the same, the facility is located in the same area or within a predetermined range, or the rank of the facility in a predetermined stage evaluation is the same. The generated information is presented to the user via the user terminal.

[0030] The proxy transaction unit 134 executes a proxy purchase process to purchase or reserve an NFT circulating on the network on behalf of a user based on a request from the user or based on other conditions. The proxy purchase process may include a series of processes for purchasing or reserving an NFT on behalf of a user, such as a bidding process, a settlement process, and an instruction to change the owner of the NFT, receiving the NFT, etc.

[0031] <User device> The user terminal 200 is used by a user who utilizes the services provided by the above service provider to view information related to NFTs, make purchase requests (bid requests), acquire NFTs, make facility reservations, make payments, etc. The user terminal 200 can be, for example, an information processing device such as a personal computer, a tablet terminal, a smartphone, a mobile phone, or a PDA.

[0032] Fig. 3 is a functional block diagram showing the user terminal 200 of Fig. 1. The user terminal 200 includes a communication unit 210, a storage unit 220, a control unit 230, an input unit 240, and an output unit 250.

[0033] The communication unit 210 is a communication interface for communicating with the communication unit 110 of the server device 100 via a network, and communication is performed according to a communication protocol such as TCP / IP. The communication unit 210 may include, for example, a communication device using a known short-range wireless communication technology. As such a short-range wireless communication technology, for example, WiFi, Bluetooth (registered trademark), RFID (Radio Frequency IDentification), etc. can be used.

[0034] The storage unit 220 stores programs for executing various control processes and functions in the control unit 230, input data, etc., and is composed of a RAM, a ROM, a flash memory, etc. The storage unit 220 also temporarily stores the contents of communication with the server device 100.

[0035] The control unit 230 controls the overall operation of the user terminal 200 by executing the programs stored in the storage unit 220, and is composed of a CPU, a GPU, etc. It is preferable that the programs are stored in a non-volatile storage medium among the storage media constituting the storage unit 220.

[0036] The input unit 240 is a component for allowing a user to input instructions (requests) and the like, and is composed of, for example, a touch panel, operation buttons, a keyboard, a mouse, a microphone for voice input, and the like.

[0037] The output unit 250 outputs various information and presents it to the user. The output unit 250 is composed of, for example, a display (monitor) that displays images, text, etc., a touch panel, a speaker for audio output, etc.

[0038] The user terminal may include, for example, a camera for taking still images and videos, and a fingerprint sensor for detecting the user's fingerprint. Image data taken by the camera and detected fingerprint data can be stored in the storage unit 220, or transmitted to an external device or the like via the communication unit 210.

[0039] <NFTマーケット> The NFT market 300 is a marketplace where NFTs are traded, such as "OpenSea," and where, for example, information on NFTs is viewed, listed, bid, purchased, sold, and settled. The NFT market 300 may be realized by an information processing device such as a server device that performs the various processes related to NFTs described above.

[0040] The owners of the NFTs handled by the NFT Market 300 are managed on the blockchain 400. The blockchain 400 records the provenance of the NFTs handled by the NFT Market 300, and the blockchain 400 certifies the ownership of the NFTs.

[0041] When an NFT transaction (buying and selling) is completed, the NFT market 300 executes a process to change the owner of the NFT to be purchased to the purchaser of the NFT on the blockchain 400. As a result, the owner of the NFT recorded on the blockchain 400 is changed to the purchaser. Accordingly, the NFT information in the NFT market 300 is also updated. In this example, the purchaser is the user who requested a proxy purchase from the server device 100, or the administrator who manages the server device 100 that purchases on behalf of the user.

[0042] The following describes a method for purchasing NFTs using the system 1. As shown in Fig. 4, first, the server device 100 acquires information about NFTs from at least one of the NFT market 300 and the blockchain 400 (NFT information acquisition process S1).

[0043] Based on the acquired information, the server device 100 generates a display screen image to be displayed on the screen of the user terminal 200, and presents information about the NFT to the user (NFT information presentation process S2). The user can communicate with the server device 100 via a browser or application software of the user terminal 200, and view images sent from the server device 100. The information acquired and generated by the server device 100 is stored in the memory unit of the server device 100 as appropriate.

[0044] The NFT information presentation screen displayed on the user terminal 200 may include at least one of the following: facility information including the name, area, and information regarding facilities inside and outside the facility associated with the NFT; listing status information regarding whether or not the item is listed; and price information such as the desired selling price and estimated price.

[0045] The user selects an NFT that he or she wishes to purchase via the user terminal 200 and transmits purchase request information to the server device 100. The server device 100 accepts the purchase request information transmitted from the user terminal 200 (purchase request reception process S3). The server device 100 assigns identification information (purchase request ID) to each purchase request and stores it in the storage unit.

[0046] The purchase request information includes, for example, at least one NFT information to be purchased. The purchase request information may include information on multiple NFTs to be purchased. The user may also select a target facility (without selecting an NFT). In that case, one or more pieces of NFT information corresponding to the facility selected by the user are automatically selected and stored as purchase request information. The user may specify the facility to be used, the date to be used, or the price (upper limit price, lower limit price, desired price) as the purchase request information. The date may be specified by a day, hour, or minute, such as limited to one day on January 1, 2023, limited to one hour from 10:00 a.m., limited to use from 10:30 a.m. to 30 minutes, or the like, or a range with a width of a predetermined period may be specified, such as any day in January 2023. In addition, it is also possible to specify use for a predetermined time within a predetermined period, such as any two nights in January 2023. The server device 100 can refer to the NFT information stored in the memory unit, select all NFTs that meet the conditions, and execute the proxy transaction processing.

[0047] The server device 100 may present an NFT search screen to the user terminal 200. In this case, the user inputs (or selects from options) search condition information such as desired facility information, local information, listing status information, price information, etc., on the search screen. The server device 100 determines NFT information that matches the search conditions based on the input information, and presents it to the user terminal 200 as a search result. The user can select a desired NFT from among the NFTs that match the search conditions specified by the user, and make a purchase request.

[0048] The server device 100 purchases or reserves NFTs circulating on the network on behalf of the user (proxy transaction process S4). For example, the server device 100 makes a bid on the NFT market 300 for an amount designated by the user or an amount less than the designated amount. Then, when a transaction on the NFT market 300 is established, the server device 100 performs a settlement process on the NFT market 300 and purchases the NFT selected by the user on behalf of the user. Note that even if a user makes a purchase request for an NFT that the owner has not put up for sale, the server device 100 can make a purchase request (bid) to the NFT owner via the NFT market 300 or the like. Then, when the owner accepts the purchase request via the NFT market 300 or the like and the transaction is established, a settlement process is performed in the same manner as normal processing on the NFT market 300, and the owner of the NFT is changed on the blockchain 400.

[0049] Here, the server device 100 may receive the purchase fee from the user in advance before the proxy purchase on the NFT market 300, or may receive the purchase fee from the user after the proxy purchase. The server device may also make a reservation for a purchase instead of a proxy purchase. In other words, the server device 100 transmits a purchase reservation to the NFT market, and when the reservation is established, the user purchases an NFT via the server device 1000. In either case, the user can trade NFTs only by communicating with the server device 100, without directly accessing the NFT market 300 or the blockchain 400.

[0050] The user can make a payment to the service operator (the administrator of the server device 100) by bank transfer, credit card, other wallet application (application that can pay fees), etc. Cash, crypto assets (virtual currency), etc. can be used for the settlement process.

[0051] The NFT market 300 executes a process on the blockchain 400 to change the owner of the NFT to be purchased to the purchaser of that NFT.

[0052] As described above, in the system of this embodiment, users can obtain information about and purchase NFTs only by communicating with the server device 100, without directly accessing the NFT market 300 or the blockchain 400. Therefore, even general users who do not have sufficient knowledge about NFTs can easily trade NFTs.

[0053] Furthermore, in the system of this embodiment, the server device 100 can also obtain information about NFTs that have not been put up for sale by the NFT owner and provide it to the user. Therefore, the user can view information about NFTs that have not yet been put up for sale, as well as NFTs that have been put up for sale, and can consider whether or not to make a purchase request to the owner, or can actually make a purchase offer by presenting a desired purchase price.

[0054] In addition, in the system of this embodiment, the control unit 130 may execute a calculation process to calculate an estimated price of the NFT based on price information of trading objects similar to each NFT, and present the calculated estimated price to the user as NFT-related information. This allows a bid at a reasonable price even for an NFT for which a desired selling price has not been presented. It is also possible to prevent users from purchasing NFTs at unreasonably high prices.

[0055] In addition, in the system of this embodiment, the control unit 130 may calculate an estimated price based on at least one of price information acquired from the NFT market and price information acquired from other websites. Also, the control unit 130 may calculate an estimated price based on both price information acquired from the NFT market and price information acquired from other websites. This can improve the accuracy of estimating the appropriate price of the NFT. The other websites may be, but are not limited to, OTA service sites, travel agency websites, real estate sales sites, shopping mall websites, etc., including facility information and price information of accommodation facilities.

[0056] Furthermore, in the system of this embodiment, when the control unit 130 receives NFT purchase requests from multiple users for one NFT, the control unit 130 may execute a process of selecting the user who inputs the highest desired purchase price as the target user for sale. This improves the accuracy of NFT transactions and makes it possible to execute NFT transactions efficiently.

[0057] In addition, in the system of this embodiment, the control unit 130 may execute a proxy transaction process in response to an NFT purchase request from a user. This makes it possible to suppress proxy purchases of unnecessary NFTs that are not in demand.

[0058] Furthermore, in the system of this embodiment, the control unit 130 may execute a process of transferring ownership of the NFT purchased or reserved on behalf of the user in response to an NFT purchase request from the user, after previously executing a proxy transaction process. This can reduce the possibility that the NFT will be purchased by another person in advance, and can increase the possibility of purchasing the NFT at a low price before the price becomes high.

[0059] Furthermore, in the system of this embodiment, the NFT may be configured so that the date and time of use of the real estate is not disclosed before the user purchases it, and the date and time of use is disclosed after the user purchases it. This can add a new interest to purchasing an NFT without knowing the date and time of use of the real estate, and disclosing it after purchase. In this case, the NFT may be configured so that the length of time during which the real estate can be used is disclosed before the user purchases it (i.e., the NFT information presented to the user includes information on the period during which the real estate can be used). This can allow the user to know the length of stay, such as one night, three nights, one year, etc., even if the date and time of use of the accommodation facility is unknown.

[0060] Furthermore, in the system of this embodiment, the control unit 130 may set an upper bid limit in the proxy bidding process for the NFT market based on the desired purchase price input by the user. For example, the control unit 130 may start bidding at a price lower than the desired purchase price input by the user, and if the transaction is not concluded, gradually increase the amount, and finally change the bid price up to the desired purchase price input by the user. This can prevent the user from purchasing an NFT at an unintended high price.

[0061] Although the preferred embodiment of the present disclosure has been described in detail above with reference to the attached drawings, the technical scope of the present disclosure is not limited to such examples. It is clear that a person having ordinary knowledge in the technical field of the present disclosure can conceive of various modified or amended examples within the scope of the technical ideas described in the claims, and it is understood that these naturally belong to the technical scope of the present disclosure. For example, the control unit 130 of the above embodiment may output at least one of the NFT information and the NFT-related information to other websites (OTA services, shopping malls, etc.) to present information about the NFT to users of other websites. This allows information about the NFT to be provided to users of other websites, and the number of users who are the target of sales can be expanded.

[0062] The series of processes performed by the device described in this specification may be realized using any of software, hardware, and a combination of software and hardware. A computer program for realizing each function of the server device 100 according to this embodiment may be created and installed in a PC or the like. A computer-readable recording medium in which such a computer program is stored may also be provided. The recording medium may be, for example, a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, or the like. The above computer program may also be distributed, for example, via a network, without using a recording medium.

[0063] In addition, the processes described herein using flowchart diagrams do not necessarily have to be performed in the order shown. Some process steps may be performed in parallel. Additional process steps may be employed, and some process steps may be omitted.

[0064] In addition, the effects described in this specification are merely descriptive or exemplary and are not limiting. In other words, the technology according to the present disclosure may achieve other effects that are apparent to a person skilled in the art from the description of this specification, in addition to or in place of the above effects.
