Description

[Technical field]

[0001] The present invention relates to a digital messaging system that uses a one-time URL type NFC device attached to a gift such as a message card to connect only the sender and recipient of the message via an Internet line, allowing the sender to send a digital message to the recipient and providing a special, real-time, two-way personal community. [Background technology]

[0002] A "gift" is a personal item given to a close person that conveys feelings of friendship, affection, etc., and is known as a communication tool that connects people. The "gifts" referred to here include various written documents (e.g., letters, postcards, message cards, invitations, colored paper, calendars, etc.), as well as "real objects" such as stuffed toys and souvenirs. On the other hand, in recent years, "virtual tools" such as e-mail and SNS (social networking services) have become popular, allowing senders to send heartfelt digital messages to recipients via the Internet.

[0003] [Patent Document 1] JP 2002-288187 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the case of gifts (such as message cards), the space for writing is limited, so it is often difficult to fully express the sender's feelings of gratitude or congratulations to the recipient. Moreover, it was only possible to express feelings by writing or drawing. On the other hand, while these problems can be solved by using e-mail, the value of the traditional "gift" sent by hand or by mail is lost. Furthermore, these conventional technologies have not been able to build a special, real-time, two-way personal community that connects only the sender and receiver of a digital message in a highly secure manner.

[0005] As a result of intensive research, the inventors discovered that all of the above problems could be solved by attaching an NFC (Near Field Communication) device that stores a URL that allows a digital message created by a sender for a recipient to be obtained via an Internet line to a real "gift." The "digital message" referred to here includes text data (message data), still image data, moving image data, and audio data, all of which have message properties. Examples of NFC devices include NFC tags and NFC cards.

[0006] Moreover, as a result of intensive research, the inventors came up with the idea that if a one-time URL type NFC device is used as this NFC device, it will be possible to issue a one-time URL at low cost that accepts acquisition requests only once or for a limited time or a limited number of times. This has the advantage that, without installing an expensive one-time URL creation unit in the mobile information terminal or server, when a mobile information terminal is held up to the NFC device, even if a web screen left in the history is redisplayed on the display, it cannot be used illegally by a third party (function to prevent the content of communication from being spread outside the community), which has been a security issue for NFC devices, can be obtained (function to prevent the content of communication from being spread outside the community), and this invention has been completed.

[0007] In other words, the present invention has been made in consideration of such conventional problems, and aims to provide a digital messaging system that can transmit to a recipient in a highly secure state a digital message that fully reflects the sender's feelings in terms of volume and expression, without compromising the sense of value that comes from handing over a "gift" by utilizing an NFC device that can issue a one-time URL attached to the gift, and that can also build a special, real-time, two-way personal community that connects only the sender and recipient of this message. [Means for solving the problem]

[0008] The invention described in claim 1 relates to a one-time URL type NFC device attached to an actual gift including a document given from a sender to a recipient, the one-time URL type NFC device having an NFC side memory unit in which an address of a community site between the sender and the recipient provided on a server is stored, and a one-time URL creation unit for issuing a one-time URL corresponding to the address, which accepts an acquisition request only once or for a limited time or a limited number of times; a sender side information terminal possessed by the sender, the sender side information terminal having a sender side communication unit for connecting to an Internet line, a sender side memory unit for storing an application for providing the community site on the server, and a sender side input unit for inputting a digital message from the sender to the recipient, site data for providing the community site, and sender side communication data to be transmitted to the recipient side information terminal via the community site; a receiver side communication unit for connecting to the Internet line; an NFC reader for reading data stored in the NFC side memory unit of the one-time URL type NFC device via near field communication; the server has a receiver-side information terminal possessed by the receiver, the receiver-side information terminal having a receiver-side input unit for inputting receiver-side communication data to be transmitted to the sender-side information terminal via a community site; a server-side communication unit for connecting to the Internet line; a server-side storage unit for storing the digital message and the site data received from the sender-side information terminal via the Internet line; and a message transmitting unit for verifying a one-time URL and transmitting the digital message stored in the server-side storage unit only to the receiver-side information terminal when the receiver-side information terminal accesses the community site. The application comprises an access program for accessing the server from the sender-side information terminal via the Internet line; an account creation program for creating an account for the sender to use the application based on an input signal from the sender-side input unit; and a one-time URL type NFC device for transmitting, via near field communication, an NFC-side storage unit of the one-time URL type NFC device based on an input signal from the sender-side input unit.A digital message system comprising: an address input program for storing an address of the community site; a message creation program for creating the digital message based on an input signal from the sender-side input unit; a site data creation program for creating the site data based on an input signal from the sender-side input unit; a data transmission program for transmitting the created digital message and the site data from the sender-side information terminal to the server via the Internet line; and an intra-community communication program for transmitting and receiving the sender-side communication data and the recipient-side communication data between the sender-side information terminal and the recipient-side information terminal via the community site.

[0009] The "digital messaging system" referred to here is a system that uses a one-time URL type NFC device attached to gifts such as message cards and souvenirs, and connects only the message sender and recipient via the Internet with high security, thereby building a special, real-time, two-way personal community. The sender and the recipient may be of any age or gender. There may be one or more senders and receivers. The relationship between the sender and the recipient is arbitrary, and may be, for example, a romantic partner, a spouse, a family member, a friend, or an acquaintance.

[0010] Here, "(real) documents" refers to documents that actually exist as physical objects, not virtual documents that are digitally represented. For example, message cards, letters, postcards, invitations, colored paper, letters of contribution, business cards, etc. may be adopted. The term "real gifts" used here refers to gifts (presents) that actually exist as physical objects, not digital virtual gifts. For example, stuffed toys, calendars, various commemorative items, incentives for corporate sales promotion, premium goods, novelty goods, etc. can be used.

[0011] A one-time URL type NFC (Near Field Communication) device is an RFID (Radio frequency identification) device that has a function for issuing one-time URLs and performs short-distance wireless communication within a few tens of centimeters. An NFC device as referred to here is any entity that has NFC capabilities, such as an NFC-enabled card, tag, smartphone, tablet, etc. This one-time URL is a mechanism that accepts an acquisition request only once or for a limited time or a limited number of times. This one-time URL type NFC device can create a unique URL that includes a signature that is sent to the community site of the server when a recipient's information terminal that has an NFC reader or NFC device reading function is held over the NFC device.

[0012] Here, an example of a mechanism for creating a one-time URL using an NFC device will be described. That is, the configuration of an NFC device for issuing one-time URLs is characterized by its security in that the UID (unique identifier), counter, part of the static data, device tampering status, and message authentication code, which are the targets of mirroring (duplicating), can be individually configured. An NFC device for issuing one-time URLs configured in this way issues a one-time URL within the device each time it is held over an NFC device reader built into the recipient's information terminal or an NFC reader external to the recipient's information terminal. Of course, the one-time URL creation unit (means for issuing a one-time URL) is not limited to this.

[0013] The power supply method of the one-time URL type NFC device is arbitrary. For example, it may be an electromagnetic induction method, a battery exchange method, various contact power supply methods, or various non-contact power supply methods. Among these, the configuration of a one-time URL type NFC device using an electromagnetic induction type non-contact power supply method includes, for example, an antenna, an NFC side communication unit having a high-frequency circuit, an NFC side storage unit of ROM or RAM, a control unit with a built-in CPU, a power receiving unit of a power supply circuit, and a one-time URL creation unit. As the NFC side storage unit, generally, a ROM or a RAM is used. The address of the server's community site and the like are stored here. Other information, for example, information on the sender, may also be stored. This makes it possible, for example, to display an image (including still images and moving images) of the sender and various information including audio on the display screen of the receiver side information terminal when the receiver side information terminal is held up to a one-time URL type NFC device.

[0014] The sender's information terminal and the receiver's information terminal may be, for example, a portable terminal such as a smartphone or a tablet, or a desktop computer. In addition, the sender's information terminal and the receiver's information terminal generally have a display for displaying various contents (information) on a screen. The configurations of the sender-side communication unit, the receiver-side communication unit, and the server-side communication unit are not limited as long as they are capable of communicating information with an Internet line.

[0015] The sender side storage unit and the receiver side storage unit may be, for example, a ROM or a RAM. The sender side storage unit may store, for example, an application for setting up a community site on a server, as well as digital messages created by the sender side information terminal, data for the site, sender side communication data, etc. On the other hand, the receiver side storage unit may store, for example, digital messages transmitted from the sender side information terminal, etc. As the sender side input section and the receiver side input section, for example, various types of key input section, voice input section, image input section (camera image pickup section), etc. can be adopted.

[0016] A digital message is an online message that a sender creates for a recipient by operating a sender-side input unit of a sender-side information terminal. The data format of the digital message may be, for example, text data, still image data, moving image data, audio data, etc. (the same applies to sender-side communication data and receiver-side communication data). The "site data" referred to here is the data necessary to set up a community site on the server. Specifically, this includes the site name, site design, and content posted on the site, as well as personal information such as the name, address, email address, account (ID), and password of recipients who use the site.

[0017] Sender communication data and receiver communication data are various types of data created by senders or receivers to convey their feelings, opinions, etc. to the other party (receiver or sender) via a community site. An NFC reader is an NFC reading device that uses short-distance wireless communication to read data stored in an NFC-side memory unit of an NFC device. This NFC reader may be built into the recipient's information terminal or may be attached externally. The NFC reader may also be an NFC reader / writer that has not only a reading function but also a rewriting function.

[0018] The server may be, for example, one managed by a digital message system operating company or a service provider affiliated with the operating company. Specifically, for example, a service program that provides HTML and object display to a web browser of client software in accordance with HTTP, or a "web server" on which that service runs, may be used. The type of the server-side storage unit is not limited. For example, a hard disk of a personal computer or various types of memory (ROM, RAM, etc.) can be used. The data stored in the server-side storage unit may be, for example, a digital message received from a sender-side information terminal and site data.

[0019] A community site is a personal site where senders and receivers connected to a server can exchange sender-side communication data and receiver-side communication data using the sender-side information terminal and receiver-side information terminal that each of them owns. This community site is operated by a server (including a cloud server) connected to the Internet, and its database (server-side memory unit) stores various templates and content as a service to users (senders, receivers, etc.). The message sending means is logic that, when the community site is accessed from the recipient's information terminal, verifies the one-time URL and sends the digital message stored in the server-side memory unit from the server only to the recipient's information terminal.

[0020] The type of recording medium on which the application is recorded before use is arbitrary. For example, a CD-ROM, a DVD, a USB memory, an SD card, or a database on a server (including a cloud server) can be used. The application can be acquired (installed) on the sender's smartphone, for example, by installing it from this server (including the cloud) over the Internet. Alternatively, the application can be acquired from a CD, DVD, USB memory, SD card, etc. on which the application is stored.

[0021] The access program in the application is logic for accessing the server from the sender's information terminal via an Internet line. The account creation program is logic for creating an account for the sender to use an application based on an input signal from the sender's input unit. The address input program is logic that stores the address of a community site in the NFC side memory unit of the one-time URL type NFC device based on an input signal from the sender side input unit of the sender side information terminal via short-range wireless communication. The message creation program is logic for creating a digital message based on an input signal from the sender's input section. Furthermore, the site data creation program is logic for creating site data based on an input signal from the sender side input unit.

[0022] The data transmission program is logic for transmitting the created digital message and site data from the sender's information terminal to the server via an Internet line. The intra-community communication program is logic for transmitting and receiving sender-side communication data and receiver-side communication data between a sender-side information terminal and a receiver-side information terminal via a community site.

[0023] The invention described in claim 2 is the digital message system described in claim 1, characterized in that the one-time URL type NFC device is a non-contact power supply type tag that utilizes electromagnetic induction, the gift is a flip calendar in which multiple calendar papers are stacked together and the year is changed by turning over the calendar papers, and the one-time URL type NFC device is attached to the calendar paper of the last page including the backing paper of the flip calendar, while the remaining calendar papers have multiple tag holes formed in a mutually communicating state at the position facing the one-time URL type NFC device to prevent a decrease in efficiency of electromagnetic induction caused by each of the stacked calendar papers.

[0024] The type of flip calendar is not limited as long as the calendar can be changed by turning over a number of overlapping calendar sheets. For example, it may be a daily flip calendar or a monthly flip calendar. For example, the last page may or may not have a mount, which is a type of calendar paper. The one-time URL type NFC device (tag) may be attached to any position on the last page of the calendar paper. For example, it may be attached to the top or bottom edge of the calendar paper. The shape of each tag hole may be any shape, such as a circle, an ellipse, a triangle or a polygon having more than one side. The tag holes are connected to each other to effectively prevent a decrease in efficiency of electromagnetic induction caused by the stacked calendar papers.

[0025] The invention described in claim 3 is a digital message system described in claim 1 or claim 2, characterized in that the gift is any of a message card, letter, postcard, invitation, colored paper, message, business card, stuffed animal, calendar, various commemorative items, incentive goods used as sales promotion aids for companies, premium goods, and novelty goods. Effect of the Invention

[0026] According to the present invention, the sender accesses the server by activating an application previously installed on the sender's information terminal, and operates the sender's input unit to register an account and create a digital message to be sent to the recipient, and a community site that connects senders and recipients is also provided within this server. Then, the sender attaches a one-time URL type NFC device, in which the address of the community site is stored in the NFC memory unit, to a real gift (including a paper document) that the sender wishes to give to the recipient. The sender then either hands the gift over to the recipient or delivers it via mail, courier, or other method.

[0027] When the recipient holds (touches) the recipient's information terminal over the one-time URL type NFC device, the NFC reader uses short-distance wireless communication to read the address (URL) of the community site stored in the NFC side memory of the one-time URL type NFC device. This automatically starts up the recipient's information terminal and accesses the community site on the server via the Internet. On the other hand, in the accessed server, a message transmitting means verifies the one-time URL sent from the recipient's information terminal, and if there is no fraud, transmits the digital message stored in the server's memory section only to the recipient's information terminal via the Internet line. Thereafter, the sender and the receiver use the community site to transmit and receive the sender-side communication data and the receiver-side communication data only between the sender-side information terminal and the receiver-side information terminal.

[0028] This makes it possible to use an NFC device that can issue a one-time URL attached to a gift, without compromising the sense of value that comes from handing over a gift, and to send a digital message to the recipient in a highly secure manner that fully reflects the sender's feelings in terms of both volume and expression. Furthermore, the sender and the receiver can then use this community site to build a special, real-time, two-way personal community that connects only with each other.

[0029] In particular, according to the present invention as set forth in claim 2, a one-time URL type NFC device (tag) of a non-contact power supply type utilizing electromagnetic induction is attached to the last page of the calendar paper including the mount of the flip calendar. On the other hand, in the remaining calendar paper, a plurality of tag holes are formed in mutually communicating positions at positions facing the one-time URL type NFC devices. This makes it possible to prevent a decrease in the efficiency of electromagnetic induction caused by each stacked calendar paper when the NFC reader of the recipient's information terminal is held over the one-time URL type NFC device of the flip-calendar.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] Examples of the present invention will now be described in detail. EXAMPLES

[0032] In FIG. 1, reference numeral 10 denotes a digital message system (hereinafter, referred to as the digital message system) according to a first embodiment of the present invention. This digital message system 10 includes an oval one-time URL type NFC card (one-time URL type NFC device) 12 embedded in a message card (an actual gift including a written document) 11 given by a sender, John, to his girlfriend, Yoko, who is the recipient, an Internet line 13, a sender-side smartphone (sender-side information terminal) 14 carried by the sender, a recipient-side smartphone (recipient-side information terminal) 15 carried by the recipient, a server 17 having a personal community site 16 between the sender and the recipient, and an application 18 (see FIG. 4) installed in the sender-side smartphone 14 for sending a digital message created by the sender-side smartphone 14 to the recipient-side smartphone 15 via the Internet line 13 and for establishing the community site 16 between the sender and the sender in the server 17.

[0033] These components will now be described in detail. 1 and 2, the message card 11 is a rectangular card of approximately postcard size, with the subject (message for you), destination (Yoko), and sender (John) printed on its front. In addition, a business card-sized one-time URL type NFC card 12 is embedded in the center of the message card 11.

[0034] The one-time URL type NFC card 12 is a radio frequency identification (RFID) card that uses a short-range wireless communication method with a frequency of 13.56 MHz standardized by ISO / IEC 18092. The one-time URL type NFC card 12 operates using power supplied contactlessly from the recipient's smartphone 15, similar to a passive wireless tag.

[0035] As shown in the block diagram of Figure 3, in this one-time URL type NFC card 12, a spiral antenna 20, an NFC side communication unit 21, an NFC side memory unit 22, an NFC side control unit 23, a power receiving unit 24, and a one-time URL creation unit 25 are arranged on the surface of a rectangular plastic plate 19 made of synthetic resin. The NFC-side communication unit (high frequency circuit) 21 is means for performing short-distance wireless communication with the recipient-side smartphone 15 located nearby (for example, within a few tens of centimeters).

[0036] The NFC side storage unit 22 is a means for storing the address of the community site 16 provided on the server 17, card identification data for individually identifying this one-time URL type NFC card 12, and the like. The NFC side control unit 23 has a built-in CPU and is a means for controlling the entire one-time URL type NFC card 12. The power receiving unit 24 has a power circuit and is means for receiving power from the recipient's smartphone 15 through the NFC-side communication unit 21 in a wireless manner.

[0037] The one-time URL creation unit 25 is used to create (issue) a unique URL including a signature that is sent to the server 17 when the one-time URL type NFC card 12 is held over an NFC reader / writer (NFC reader) 26 built into the recipient's smartphone 15. This one-time URL generating unit 25 has a configuration for issuing a unique one-time URL each time a card is touched, using some or all of the counter, card tampering status, and message authentication code.

[0038] Here, a specific example of issuing a one-time URL by one-time URL generator 25 will be described. In other words, each time the NFC reader / writer 26 of the recipient's smartphone 15 is held over the one-time URL type NFC card 12, the one-time URL creation unit 25 dynamically changes some or all of the counter, card tampering status, and message authentication code, and a one-time URL is issued by the one-time URL type NFC card 12.

[0039] Next, the sender smartphone 14 will be described with reference to FIG. 1 and FIG. The sender's smartphone 14 is a type of portable information terminal that is connected to the Internet line 13 via the sender's communication unit 27 . The sender smartphone 14 has a sender memory unit 28 that stores an application 18 for setting up a community site 16 on the server 17, a sender key input unit (sender input unit) 29 that inputs digital messages from the sender to the recipient, site data for setting up the community site 16, and sender communication data to be sent to the recipient smartphone 15 via the community site 16, a sender camera unit (sender input unit) 30, a sender microphone (sender input unit) 31, a sender display unit 32 as a display unit, and a sender control unit 33 that controls the entire electrical (electronic) system of the sender smartphone 14.

[0040] The sender side memory unit (which is the same as the receiver side memory unit described below) 28 employs a RAM that allows data to be freely read and written. A digital message is an online message consisting of text data created by a sender for a recipient using the sender's key input unit 29 of the sender's smartphone 14. In addition, it may be, for example, camera image data (still image data, moving image data) created using the sender's camera unit 30, or audio data created using the sender's microphone 31. The site data is data necessary to set up the community site 16 on the server 17. Specifically, this data includes the site name, site design (site structure), and content posted on the site, as well as personal information such as the address, name, email address, URL, account (ID), and password of senders (and receivers, if necessary) who use the site. The sender control unit 33 has a built-in CPU and controls the sender smartphone 14 as a whole.

[0041] Next, the recipient's smartphone 15 will be described with reference to FIGS. This recipient's smartphone 15 is a type of portable information terminal connected to the Internet line 13 via a recipient's communication unit 34, and has a recipient's display unit 35 as a display unit, an NFC reader / writer 26, a recipient's memory unit 36, a recipient's control unit 37 that controls the entire electrical system of the recipient's smartphone 15, a recipient's key input unit 50 that inputs recipient's communication data to be sent to the sender's smartphone 14 via the community site 16, a recipient's camera unit 51, and a recipient's microphone 52. The NFC reader / writer 26 reads the data stored in the NFC-side storage unit 22 of the one-time URL type NFC card 12 via short-distance wireless communication. The receiver-side control unit 37 has a built-in CPU and controls the receiver-side smartphone 15 as a whole.

[0042] Next, the server 17 will be described with reference to FIG. This server 17 is a computer (here, a cloud computer) operated by the operating company of the digital message system 10. The server 17 has a server-side communication unit 38 for connecting to the Internet line 13, a server-side memory unit (database) 39 for storing digital messages, site data, sender-side communication data, etc. received from the sender-side smartphone 14 via the Internet line 13, a server-side control unit 40 which has a built-in CPU and controls the entire server 17, the community site 16, and a message sending means 41 which includes a one-time URL verification means 70.

[0043] Specifically, this server 17 registers senders who are users and manages the registered information, manages the community site 16 (personal community management (information management between senders and receivers)), creates and stores messages (text, video, images, audio, templates), displays messages, encrypts and decrypts message data, manages NFC data (registers, updates, deletes), and obtains and displays statistical information (access information). In particular, when the community site 16 is accessed from the recipient's smartphone 15, the message sending means 41 verifies the one-time URL using the verification means 70, and then sends the digital message stored in the server-side memory unit 39 only to the recipient's smartphone 15.

[0044] Next, the application 18 will be described with reference to FIG. The application 18 includes an access program P1 for accessing the server 17 from the sender smartphone 14 via the Internet line 13, an account creation program P2 for creating an account for the sender to use the application 18 based on an input signal from the sender key input unit 29, an address input program P3 for storing the address of the community site 16 in the NFC side memory unit 22 of the one-time URL type NFC card 12 based on an input signal from the sender key input unit 29 via short-range wireless communication, a message creation program P4 for creating a digital message based on the input signal from the sender key input unit 29, a site data creation program P5 for creating site data based on the input key signal from the sender key input unit 29, a data transmission program P6 for transmitting the created digital message and site data from the sender smartphone 14 to the server 17 via the Internet line 13, and an intra-community communication program P7 for transmitting and receiving sender communication data and receiver communication data between the sender smartphone 14 and the receiver smartphone 15 via the community site 16.

[0045] These programs will be described in detail below. In the access program P1, the installed application 18 is started, whereby the sender smartphone 14 accesses the address of the server 17 that is stored in advance in the application 18. In the account creation program P2, the sender uses the sender's key input unit 29 to register personal information including the sender's name, address, telephone number, email address, credit card number, etc., to create an account. In the address input program P3, the sender uses the sender's key input unit 29 to store the address of the community site 16 in the NFC-side storage unit 22 of the one-time URL type NFC card 12 via short-distance wireless communication.

[0046] In the message creation program P4, the sender uses the sender key input unit 29 to create a digital message for the recipient. At that time, the sender may use the sender camera unit 30 of the sender smartphone 14 to add still image data (including icons, stamps, etc.) or video data that the sender wants to deliver to the recipient. Similarly, the sender's voice may be added using the sender microphone 31 of the sender smartphone 14. Note that in this message creation program P4, a digital message may be created using a template prepared in advance.

[0047] In the site data creation program P5, the sender creates site data using the sender-side key input unit 29 of the sender-side smartphone 14. Site data includes the site name (for example, the recipient's name or nickname), the site design, the contents posted on the site, and personal information of the recipient who uses the site, such as the name, address, email address, account (ID), and password. In the data transmission program P6, the created digital message and site data are transmitted from the sender's smartphone 14 to the server 17 via the Internet line 13. The server 17 that receives the data creates a (personal) community site 16 between senders and recipients based on the received site data.

[0048] In the intra-community communication program P7, the sender-side communication data and the receiver-side communication data are transmitted and received between the sender-side smartphone 14 and the receiver-side smartphone 15 via the community site 16. The sender's communication data and the receiver's communication data are various types of data created by the sender or receiver to convey their feelings, opinions, etc. to the other party (receiver or sender) via the community site 16.

[0049] In addition, this application 18 may also perform other functions, such as: (1) displaying the sending date and time and the receiving date and time of a digital message on the sender display unit 32 of the sender smartphone 14; (2) inviting the recipient to a ceremony, festival, conference, event, party, meeting, etc. from the sender; (3) checking the registration status of the recipient's participation or non-participation in these invitations (list screen, Excel download); (4) setting whether or not to disclose the invitee; (5) registering the recipient's participation or non-participation; and (6) NFC management (registering, updating, deleting one-time URL type NFC card 12).

[0050] NFC management here includes (a) registration of personal community names, (b) registration and setting of sub-community names, (c) writing to an NFC that can issue a one-time URL for the sub-community (there is a setting that prevents rewriting by the recipient), (d) linking and updating the recipient's attributes with the sub-community URL you want to show to that recipient (the same URL can be used for all multiple recipients or different URLs can be used), (e) bulk registration, update (including linking), and deletion of multiple NFCs (Excel upload), (f) checking the NFC registration status (list screen, Excel download (registration and update dates and times are automatically obtained)), (g) registering multiple URLs to one NFC, and (h) obtaining / displaying statistical information (access status) (list screen, Excel download).

[0051] Next, the operation of the digital message system 10 using the one-time URL type NFC card 12 according to the first embodiment of the present invention will be described with reference to FIGS. First, as shown in FIG. 2, the sender purchases the application 18 and the message card 11. Thereafter, as shown in Figures 1, 2 and 4, application 18 is installed in sender's smartphone 14, and application 18 is launched, causing sender's smartphone 14 to access the address of server 17 previously stored in application 18 (access program P1).

[0052] Thereafter, the sender uses the sender's key input unit 29 to register personal information including the sender's name, address, telephone number, email address, credit card number, etc., thereby creating an account (account creation program P2). Next, via short-range wireless communication, the sender uses the sender-side key input unit 29 to store the address of the community site 16 on the server 17 in the NFC-side memory unit 22 of the one-time URL type NFC card 12 (address input program P3). Thereafter, the sender uses the sender-side key input unit 29 of the sender-side smartphone 14 to create a digital message for the recipient (message creation program P4). At this time, still image data or video data that the sender wants to deliver to the recipient may be added using the sender camera unit 30 of the sender smartphone 14. Similarly, the sender's voice may be added using the sender microphone 31 of the sender smartphone 14. Note that in this message creation program P4, a digital message may be created using a template (including icons, stamps, etc.) prepared in advance.

[0053] Meanwhile, the sender creates site data using the sender-side key input unit 29 of the sender-side smartphone 14 (site data creation program P5). The site data includes the site name (for example, the recipient's name or nickname), the site design, the contents posted on the site, and personal information of the recipient who uses the site, such as the name, address, email address, account (ID), and password.

[0054] Next, the created site data and digital message are transmitted from the sender's smartphone 14 to the server 17 via the Internet line 13 (data transmission program P6). When the server 17 receives this, it creates a (personal) community site 16 between the sender and the recipient based on the site data. If there are multiple recipients, a sub-community site may be created for each recipient. In this case, the name of each sub-community may be the personal name or nickname of the corresponding recipient.

[0055] Also, when there are multiple receivers making up a sub-community site, the site name may be the group name. Furthermore, when there are multiple receivers, the sender sets whether the sub-community site is to be "one-to-one", "one-to-many", "many-to-many" between sender and receiver, or one-to-one between receivers. However, "many-to-many" sub-community sites between receivers are not permitted. The reason for this is that any one of the multiple receivers can install application 18 on his / her own receiver-side smartphone 15 and become the sender.

[0056] Next, as shown in FIG. 2, the sender hands the message card 11 with the one-time URL type NFC card 12 thus obtained to the recipient as a gift, or delivers it via mail, parcel delivery, or the like. Then, as shown in Figures 1, 2 and 5, the recipient (Yoko) who receives the message card 11 reads the "message for you" from the sender (John) written on the front of the message card 11 and holds up (touches) the recipient's smartphone 15, anticipating the contents. As a result, using short-range wireless communication, the NFC reader / writer 26 reads the address (one-time URL) of the community site 16 stored in the NFC side memory unit 22 of the one-time URL type NFC card 12, automatically starts up the recipient's smartphone 15, and accesses the community site 16 on the server 17 via the Internet line 13.

[0057] Meanwhile, in the server 17 that has been accessed, the one-time URL sent from the recipient's smartphone 15 is verified by the message sending means 41 using the verification means 70, and if no fraud is found, the digital message stored in the server-side memory unit 39 is sent only to the recipient's smartphone 15 via the Internet line 13. Thereafter, the sender and receiver use this personal community site 16 to send and receive sender communication data and receiver communication data only between the sender's smartphone 14 and the receiver's smartphone 15 (community communication program P7). The sender's communication data and the receiver's communication data referred to here are various types of data created by the sender or receiver to convey their feelings, opinions, etc. to the other party (receiver or sender) via the community site 16.

[0058] Specifically, the sender operates the sender key input unit 29 of the sender smartphone 14 to create sender communication data (text data) to be sent to the recipient. Meanwhile, the recipient operates the recipient key input unit 50 of the recipient smartphone 15 to create recipient communication data (text data) to be sent to the sender. In this case, the sender and receiver may use the sender camera unit 30 of the sender smartphone 14 or the receiver camera unit 52 of the receiver smartphone 15 to add still image data (including icons, stamps, etc.) or video data that they want to deliver to each other. Similarly, the voice of the sender or receiver may be added using the sender microphone 31 of the sender smartphone 14 or the receiver microphone 52 of the receiver smartphone 15. Note that in this intra-community communication program P7, each piece of communication data may be created using a template prepared in advance on the server 17 (community site 16).

[0059] This allows a digital message that fully reflects the sender's feelings in terms of volume and expression to be sent to a recipient in a highly secure manner, without compromising the preciousness of handing over a "message card (gift) 11" by hand, and by using a one-time URL type NFC card 12 that can issue a one-time URL attached to the message card 11. Furthermore, thereafter, the sender and the receiver can use this community site 16 to build a special, real-time, two-way personal community that connects only with each other. In addition, by using a one-time URL type NFC device for communication within the community, it is possible to prevent the spread of messages outside the community even without a smart device app. This allows for the sending and receiving of special, real-time, interactive online messages that connect only the sender and receiver of the message.

[0060] Second Embodiment Next, a digital message system according to a second embodiment of the present invention will be described with reference to FIG. As shown in FIG. 6, the feature of the digital message system 10A of the second embodiment is that, instead of the message card 11 of the first embodiment, senders John and Yoko deliver a wedding invitation (a gift including a document) 11A with an embedded one-time URL type NFC tag 12A to three friends who are recipients by hand delivery or mail, and create a personal group community site 16A between these people that connects the sender's smartphone 14 with each of the friends' recipient's smartphones 15A to 15C via an Internet line 13. This will enable the couple, John and Yoko, and their three friends to send and receive messages interactively in real time, such as confirming their participation in the wedding or sending congratulatory messages. Other configurations, operations, and effects can be inferred from the first embodiment, and therefore description thereof will be omitted.

[0061] Third Embodiment Next, a digital message system according to a third embodiment of the present invention will be described with reference to FIG. As shown in FIG. 7, the digital message system 10B of the third embodiment is characterized in that, instead of the one-time URL type NFC card 11 of the first embodiment, a monthly flip calendar (gift, flip calendar) 61 is adopted in which multiple calendar papers (calendar papers) 60 are stacked on top of each other and the calendar can be changed by turning over the calendar papers 60. The monthly calendar 61 is made by binding the top end of each of 12 calendar sheets 60, on which the months from January to December are displayed, to the top end of the last page of a mount (calendar sheet) 62.

[0062] A one-time URL type NFC tag 12B of a contactless power supply type that utilizes electromagnetic induction is affixed to the surface of the lower right part of the backing paper 62, and at the position facing the one-time URL type NFC tag 12B in each calendar paper 60, a plurality of tag holes 63 for exposing the one-time URL type NFC tag 12B from the surface of the monthly calendar 61 are formed in a mutually communicating state. This prevents a decrease in the efficiency of electromagnetic induction of one-time URL type NFC tag 12B due to the paper surfaces of each stacked calendar paper 60 when NFC reader / writer 26 of the recipient's smartphone 15 is held over one-time URL type NFC tag 12B of monthly calendar 61. The other configurations, operations, and effects can be inferred from the first embodiment, and therefore will not be described.

[0063] Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments without departing from the spirit of the present invention. 8, examples of actual gifts including documents include a birthday card 100, another wedding card 101, a business card 102, a postcard 103, a letter 104, and a message 105, each of which has a one-time URL type NFC tag 12C attached thereto. In addition, examples of actual gifts including documents include a stuffed animal 106, a key holder 107, and various gifts 108, each of which has a built-in one-time URL type NFC device (not shown).
