Here, ticket data or images such as photographs are sometimes treated as digital information instead of being printed on tangible media such as paper. For example, a digital ticket can be displayed on a user terminal such as a smart phone. If a digital ticket can be handled on a user terminal such as a smart phone, it will be very convenient for the user. Moreover, if an image can be displayed on a user terminal such as a smart phone, the enjoyment of the user will increase.

The inventors came up with the idea of using non-fungible tokens (Non-Fungible Tokens: NFTs) in the blockchain for valuable digital data such as ticket data or images.

NFT is a type of token whose owner is recorded on the blockchain. Tokens in blockchain include non-fungible tokens and fungible tokens. Fungible Tokens may have currency properties, such as being interchangeable with fiat currency.

Unlike such fungible tokens, NFTs are non-fungible tokens. NFTs are recorded on a blockchain whose owner is a distributed ledger computer system. Using this, NFTs are used to trade digital data such as game items or digital art.

Since NFT transactions are carried out on the blockchain, in general, fungible tokens (crypto assets) on the blockchain are required to obtain NFTs. A fungible token (cryptographic asset) in a blockchain is, for example, Bitcoin or Ether.

However, blockchain is not yet popular enough for many people to use it. For this reason, even if you try to use NFT for transactions of valuable digital data such as ticket data or images, users who are not familiar with blockchain and do not own fungible tokens (cryptographic assets) may find such Getting an NFT may not be easy.

Therefore, in order to facilitate the acquisition of NFT, the present inventors have developed products that are manufactured by printing on a tangible medium such as paper, such as the ticket of Patent Document 1 or the photograph of Patent Document 2. A novel idea of using the issuing device was obtained. Note that the issuing device here is, for example, the ticket issuing device of Patent Document 1 or the multi-function device for the content print service of Patent Document 2.

Both the ticket of Patent Document 1 and the photograph of Patent Document 2 are types of products issued by printing. Contents such as tickets or photographs printed on a tangible medium such as paper can be easily obtained at stores such as convenience stores. A technology or a related technology that makes it possible to obtain NFTs using such easily available products is desired.

A certain aspect of the present disclosure is a method of manufacturing a product. In the disclosed method, first identification information for identifying a product manufactured by printing is acquired by an issuing device for printing the product, and printing of the product identified by the first identification information is performed. data from an external device via a network using the first identification information, and the issuing device prints the data for printing, wherein the first The data for printing of the product identified by the identification information includes data of a machine-readable code, the code being recorded on a blockchain, the management system of non-fungible tokens is used to print the product. indicating at least second identification information for identifying a commodity non-fungible token associated with associated data, wherein the code, when read by a terminal, transmits the second identification information indicated by the code to the management system; is obtained from the terminal, and the management system is used to transmit the commodity non-fungible token identified by the second identification information to a blockchain account utilized in the terminal that read the code. .

<2. Example of manufacturing method and system for products manufactured by printing>

<2.1 First Embodiment: Ticket Issuing System>

FIG. 1 shows an example of a system 500 according to the first embodiment. The product in the first embodiment is a printed ticket 1 . Ticket 1 is a tangible object. A system 500 according to the first embodiment is used to issue and use a ticket 1 . The system 500 according to the first embodiment also handles the digital ticket 13A displayed on the user terminal 30. FIG.

A ticket 1 is, for example, a ticket for admission to an event, a ticket for admission to a facility, a ticket for a vehicle, a ticket for enjoying other services, a ticket in exchange for a product, a gift certificate, or a discount coupon. Events are, for example, concerts, movies, plays, exhibitions, expositions, sporting events, and festivals. Facilities are, for example, amusement parks, zoos, botanical gardens, art galleries, museums, movie theaters, shops, and tourist facilities. Vehicles are, for example, planes, ships, trains, buses, and taxis.

For example, ticket 1 is configured by printing ticket data on ticket paper. The ticket data, as shown in FIG. 1, includes, for example, venue, event name, date and time, seat, and ticket number. A ticket number is a number unique to each ticket. Here, as an example, it is assumed that the ticket number is the same as the ticket exchange number (first identification information) described later. The ticket shown in FIG. 1 is given "abcdefg" as a ticket number (exchange number; first identification information).

A machine-readable code 1A is attached to the ticket 1 by printing together with the ticket data described above. Code 1A is, for example, a two-dimensional code. Code 1A will be described later. Code 1A also constitutes ticket data.

The digital ticket 13A is an electronic version of the ticket data and other data included in the ticket 1. The digital ticket 13A includes, as ticket data, data relating to, for example, venue, event name, date and time, seat, and ticket number. The digital ticket 13A is stored in a database 13, which will be described later.

A user who is a purchaser of ticket 1 may use ticket 1 or digital ticket 13A when entering an event. The ability to use the digital ticket 13A eliminates the need for the user to bring the paper ticket 1 when entering an event or the like, improving user convenience. Moreover, since the user can obtain not only the digital information of the digital ticket 13A but also the tangible object of the paper ticket 1, the user has a high sense of purchase, which is preferable.

The system 500 according to the first embodiment includes an issuing device 200 and a ticket issuing server 300. The issuing device 200 is installed, for example, in a retail store. A retail store is, for example, a convenience store, a supermarket, or a department store. The issuing device 200 is configured to issue a ticket 1 by printing ticket data on a ticket paper. The issuing device 200 is installed, for example, at a checkout counter of a store and operated by store staff. The issuing device 200 may be installed in the store so that customers can directly operate it.

Upon receiving an operation by an operator such as a store staff member or a customer (user), the issuing device 200 acquires necessary ticket data from the ticket issuing server 300 outside the store, and prints the ticket data to generate a ticket 1. to be issued. The issuing device 200 is configured to receive an input of a ticket exchange number, which will be described later. Input of the exchange number is performed, for example, by operating a key or reading a code indicating the exchange number with a reader.

The issuing device 200 is configured to accept a payment operation for the price of the ticket 1 and execute payment processing for settlement of the price prior to the issuance of the ticket 1. Ticket 1 is issued after the payment process is completed. Payment is made, for example, by cash, credit card, electronic money, or direct debit from a bank account. A person (user) who intends to purchase the ticket 1 can pay for the ticket 1 at a store such as a convenience store, so the ticket 1 can be easily obtained. Also, by paying for the ticket 1 at the store, a non-fungible token 101, which will be described later, can be obtained. Since the issuing device 200 can process payment, the issuing device 200 can also be regarded as the payment processing device 200 .

It should be noted that the system 500 preferably includes a plurality of issuing devices 200. Each of the plurality of issuing devices 200 is installed in the store.

The ticket issuing server 300 is connected to the issuing device 200 via the network 15 such as the Internet. The ticket issuing server 300 is an external device installed at a location separate from the issuing device 200 so that a plurality of issuing devices 200 can be connected. The ticket issuing server 300 has ticket data for a ticket 1 issued by the issuing device 200 and is configured to transmit the ticket data to the issuing device 200 in response to a request from the issuing device 200 .

The ticket issuing server 300 is composed of a computer equipped with a processor and memory. The ticket issuing server 300 may be composed of one computer, or may be composed of a plurality of computers connected via the network 15 . A memory is connected to the processor. Memory includes, for example, a primary storage device and a secondary storage device. A primary storage device is, for example, a RAM. The secondary storage device is, for example, a hard disk drive (HDD) or solid state drive (SSD). The memory contains computer programs that are executed by the processor. The processor reads and executes computer programs stored in memory. A computer program for the ticket issuing server 300 has program code for causing a computer to function as the ticket issuing server 300 .

The system 500 according to the first embodiment can include a ticket reservation web server 400 connected to the network 15. The ticket reservation web server provides a web site that is browsed by ticket 1 purchasers. This website accepts a ticket 1 reservation operation by a person who wishes to purchase the ticket 1, and outputs the ticket 1 exchange number (first identification information). The ticket 1 exchange number is input to the issuing device 200 to issue the ticket 1 . Note that the ticket reservation web server 400 may be configured to receive a payment operation for the price of the ticket 1 and execute payment processing to settle the price. In this case, no payment is required at the store where the issuing device 200 is installed, or only the ticket issuing fee may be paid.

The ticket reservation web server 400 is composed of a computer with a processor and memory. The ticket reservation web server 400 may be composed of one computer, or may be composed of a plurality of computers connected via the network 15 . A memory is connected to the processor. Memory includes, for example, a primary storage device and a secondary storage device. A primary storage device is, for example, a RAM. The secondary storage device is, for example, a hard disk drive (HDD) or solid state drive (SSD). The memory contains computer programs that are executed by the processor. The processor reads and executes computer programs stored in memory. A computer program for the ticket reservation web server 400 has program code for causing a computer to function as the ticket reservation web server 400 .

The system 500 according to the first embodiment can include a ticket non-fungible token management system 10 (ticket NFT management system 10) connected to the network 15.

FIG. 2 shows the ticket NFT management system 10. The ticket NFT management system 10 according to the embodiment uses the blockchain 11 to manage the digital ticket 13A and the non-fungible token 101 (ticket NFT 101) associated with the digital ticket 13A.

The ticket NFT management system 10 comprises a database 13 in which digital tickets 13A are stored. The database 13 is composed of, for example, a file system connected to a network 15 such as the Internet. The file system comprises one computer or multiple computers connected to network 15 . The database 13 is configured by an IPFS (InterPlanetary File System), for example. IPFS is an example of a P2P (Peer to Peer) distributed file system. Once the digital ticket 13A is electronically issued, the digital ticket 13A is stored in the database 13. FIG.

The digital ticket 13A stored in the database 13 is displayed on the terminal 30 of the user who owns the digital ticket 13A. For example, the user can display the digital ticket 13A on the terminal 30 to enter or participate in the event.

In the embodiment, the blockchain 11 is used for managing the digital ticket 13A. The blockchain 11 is configured by a P2P (Peer to Peer) computer network system in which a plurality of computers are interconnected.

In the blockchain 11, token transactions are possible between blockchain addresses, and token transaction records are recorded in the distributed ledger of the blockchain 11. A blockchain address indicates, for example, a user account on the blockchain 11 . For example, if a user has an account 110 on the blockchain 11, the account 110 has a given blockchain address (user address).

A blockchain address is expressed, for example, as 0xZZZZZZZ. Note that each Z is independently any number or symbol, and the number of digits of Z is a predetermined number in the blockchain.

Tokens that can be traded on the blockchain 11 include fungible tokens (fungible tokens) and non-fungible tokens (non-fungible tokens: NFT). A fungible token is, for example, Ether.

Unlike such fungible tokens, NFTs are non-fungible tokens. To ensure non-fungibility, an NFT has a unique identifier in the blockchain 11 to allow it to be distinguished from other NFTs. This identifier is hereinafter referred to as the NFT identifier. The NFT identifier may also be denoted as "NFT_ID".

In the first embodiment, the digital ticket 13A is associated with the non-fungible token 101. That is, the digital ticket 13A is converted to NFT. The non-fungible token 101 associated with the digital ticket 13A is also called a "ticket NFT 101" ("NFT ticket/NFTticket" is a registered trademark in Japan). In the following, the NFT identifier (NFT_ID) of ticket NFT101 shall be represented by "A".

In the first embodiment, the correspondence between the digital ticket 13A and the ticket NFT101 is realized, for example, by associating the digital ticket 13A with NFT_ID: A of the corresponding ticket NFT101 and storing it in the database 13. When one digital ticket 13A is associated only with NFT_ID:A of one corresponding ticket NFT101, a one-to-one correspondence between the ticket NFT101 and the digital ticket 13A is realized. In the embodiment, the ticket NFT 101 itself does not need to have the ticket data included in the digital ticket 13A, so the amount of data of the ticket NFT 101 recorded on the blockchain 11 can be reduced. As a result, the cost of using the blockchain 11 can be reduced.

A single digital ticket 13A may be associated with the NFT_IDs of multiple ticket NFTs 101. When the data of each of the plurality of digital tickets 13A may be the same, such as admission tickets for events or facilities without seat assignment, even if one digital ticket 13A is associated with the NFT_ID of a plurality of ticket NFTs 101 good.

The owner (and owner history) of the ticket NFT 101 is recorded in the blockchain 11. Therefore, the owner of the ticket NFT101 does not need centralized management, and management and confirmation of the owner of the ticket NFT101 are easy. The owner of the ticket NFT101 can be easily proved by the record of the blockchain 11.

Proof of being the owner of ticket NFT101 is also proof of being the owner of digital ticket 13A. This is because the digital ticket 13A is associated with the ticket NFT 101 whose owner is recorded in the blockchain 11. Further, when the digital ticket 13A and the ticket NFT101 are associated one-to-one, when the owner of the ticket NFT101 is changed, the owner of the digital ticket 13A is also changed accordingly. That is, in the embodiment, the digital ticket 13A is associated with the ticket NFT101 so that the owner change occurs when the owner of the ticket NFT101 changes.

In the embodiment, since the record of the owner of the ticket NFT 101 recorded in the blockchain 11 can be used as the record of the owner of the digital ticket 13A, management of the owner of the digital ticket 13A itself (change of owner (including management of It is also possible to trade (sell/transfer to a third party) the ticket NFT 101 for trading the digital ticket 13A.

In the embodiment, the blockchain 11, which is a computer network system, comprises a smart contract 130. The smart contract 130 is software (computer program) implemented executable in the blockchain, and automatically executes a predetermined protocol.

The smart contract 130 has a contract address 140, which is a blockchain address. Smart contract 130 is stored at contract address 140 . Smart contract 130 is executed by being called by another computer via network 15 . Another computer that calls the smart contract 130 is, for example, the ticket NFT management server 12 or the user terminal 30, which will be described later.

A user account 110 is provided for each user in the blockchain 11. In this embodiment, the user is, for example, the owner of ticket NFT101. As will be described later, by purchasing the paper ticket 1, the user can become the owner of the ticket NFT 101 associated with the digital ticket 13A and use the digital ticket 13A.

The user account 110 has a blockchain address. In the blockchain 11, non-fungible tokens or fungible tokens owned by users are recorded in association with user accounts. The fact that the token is recorded in association with the user account (blockchain address) can also be said to be "the token is stored in the user account (blockchain address)." In addition, the fact that a token is stored in a certain account (blockchain address) can also be said to be "the account (blockchain address) owns the token". A contract address is a type of blockchain address.

If the user account 110 stores the ticket NFT 101 associated with the digital ticket 13A, the owner of the ticket NFT 101 is the user who has the user account 110. Therefore, the owner of digital ticket 13A associated with ticket NFT 101 is the user with user account 110 . As will be described later, the ticket NFT 101 is sent to the user account 110 by performing a predetermined operation after the user purchases the paper ticket 1 .

Before the ticket 1 is issued, the ticket NFT101 (NFT_ID: A) is stored in the contract address 140 of the smart contract 130 or the blockchain address managed by the smart contract 130, for example, as shown in FIG. ing. "Managed by smart contract 130" means at least that smart contract 130 can send tokens stored at its blockchain address. The accounts managed by smart contract 130 may be accounts for ticket sellers of digital tickets 13A.

The ticket NFT management system 10 according to the embodiment may include a ticket NFT management server 12. The ticket NFT management server 12 can constitute the ticket NFT management system 10 of the embodiment together with the smart contract 130 described above. The ticket NFT management server 12 is connected to the network 15 . The ticket NFT management server 12 provides functions necessary for allowing the user to obtain the ticket NFT 101 associated with the digital ticket 13A.

The ticket NFT management server 12 is composed of a computer with a processor 12A and memory 12B. The ticket NFT management server 12 may be configured by one computer, or may be configured by multiple computers connected via the network 15 . Memory 12B is connected to processor 12A. The memory 12B includes, for example, a primary storage device and a secondary storage device. A primary storage device is, for example, a RAM. The secondary storage device is, for example, a hard disk drive (HDD) or solid state drive (SSD). Memory 12B contains a computer program 12C that is executed by processor 12A. Processor 12A reads and executes computer program 12C stored in memory 12B. The computer program 12C has program code for causing the computer to function as the ticket NFT management server 12 .

The user who is the owner of the ticket NFT101 associated with the digital ticket 13A has a user terminal 30 (see FIG. 1). The user terminal 30 can be used, for example, to use the digital ticket 13A.

The user terminal 30 is, for example, a mobile device such as a smartphone or tablet. A user terminal 30 is connectable to the network 15 . The user terminal 30 is configured by a computer having a processor and memory. A memory is connected to the processor. Memory includes, for example, a primary storage device and a secondary storage device. A primary storage device is, for example, a RAM. The secondary storage device is, for example, a hard disk drive (HDD) or solid state drive (SSD). The memory contains computer programs that are executed by the processor. The processor reads and executes computer programs stored in memory. The computer program of the user terminal 30 has program code for processing such as obtaining the ticket NFT 101 and using the digital ticket 13A.

The computer program of the user terminal 30 is, for example, a wallet application program for displaying the token stored in the user account 110 of the blockchain 11 on the user terminal 30 or an application program for using the digital ticket 13A. Such application programs provide functions that allow user operations for storing tokens, sending and receiving tokens.

The computer program of the user terminal 30 has program code for displaying the NFT or fungible token associated with the user account 110 in the blockchain 11 on the display of the user terminal 30. When displaying the ticket NFT101, the computer program of the user terminal 30 displays the digital ticket 13A (ticket data) associated with the ticket NFT101.

The user's terminal 30 displays the data 13A associated with the NFT 101 owned by the user, but does not display the data associated with the NFT not owned by the user. In order to prevent data from being displayed on terminals other than the owner of NFT 101 associated with data 13A in database 13, database 13 permits access to data 13A from the owner of NFT 101 associated with data 13A. However, access control is performed so that access to the data 13A from anyone other than the owner is not permitted. The database 13 can grasp the owner of the NFT 101 associated with the data 13A by referring to the block chain 11.

FIG. 3 shows the procedure for issuing ticket 1 using the system 500 (method for manufacturing ticket 1). A person (user) who wishes to purchase a ticket 1 accesses the ticket reservation Web server 400 using the terminal 30 and performs a reservation operation for the ticket he wishes to purchase. As a result, ticket data for ticket 1 is generated (step S301: ticket reservation processing). The generated ticket data includes, for example, the venue, event name, date and time, seat, and ticket number. When the ticket data is generated, the exchange number (first identification information) of ticket 1 is also generated. Here, as described above, the ticket number also serves as the exchange number.

The ticket data is transmitted from the ticket reservation web server 400 to (the ticket NFT management server 12 of) the ticket NFT management system 10 and the ticket issuing server 300 (step S302). The ticket data transmitted to the ticket NFT management system 10 is used for generation of the ticket NFT 101 and the like. Generation of the ticket NFT101 will be described later. The ticket data transmitted to the ticket issuing server 300 is stored in the ticket issuing server 300 . The ticket data stored in the ticket issuing server 300 is transmitted to the issuing device 200 in response to a data request using the exchange number.

The ticket reservation web server 400 outputs the exchange number (first identification information) for issuing ticket 1 (step S307). The output of the exchange number may be displayed on the terminal 30, or may be sent to the user's e-mail address. The exchange number may be output in the form of a machine-readable code such as a two-dimensional code. The code may include information such as the ID of the user (ticket purchaser).

The user who has obtained the exchange number visits a store such as a convenience store and has a ticket 1 issued (steps S309 to S312). To issue the ticket 1, the user first presents the exchange number or a code indicating the exchange number to the store staff. The store staff, for example, causes the issuing device 200 to acquire the exchange number (first identification information) by reading the code indicating the exchange number with a reader (step S309). Note that the issuing device 200 may also acquire information such as a user ID.

The issuing device 200 processes payment for the ticket 1 corresponding to the exchange number (step S310). Payment processing may be performed using a settlement server (not shown). As a result, the payment for the ticket 1 is completed. The issuing device 200 acquires the ticket data after the payment is processed (step S311). The acquisition of ticket data may be performed before the payment process (step S310). The issuing device 200 uses the acquired exchange number (first identification information) to acquire the ticket data. More specifically, the issuing device 200 transmits the exchange number to the ticket issuing server 300 (step S311A). The ticket issuing server 300 that has received the exchange number transmits ticket data corresponding to the exchange number to the issuing device 200 (step S311B). The ticket data includes data of the two-dimensional code 1A, as will be described later. The ticket data is data for printing the ticket 1 .

The issuing device 200 prints the ticket data for printing the ticket 1 on the ticket paper and issues the ticket 1 (step S312). A printed ticket 1 has a two-dimensional code 1A, as shown in FIG. The two-dimensional code 1A is used, for example, to obtain a ticket NFT 101 associated with a digital ticket 13A, which is an electronic version of the ticket 1.

Upon receiving the ticket data from the ticket reservation web server 400, the ticket NFT management system 10 executes processing for the ticket NFT 101 (steps S303 to S305).

First, in the ticket NFT management system 10, processing is performed to associate the received ticket data with the NFT (initial NFT) (step S303: generate ticket NFT101). The NFT with which the ticket data is associated is issued in the blockchain 11 as an initial NFT at or before step S403. Issuance of the initial NFT is achieved by executing a prepared NFT issuance command in the blockchain 11 . When the NFT issuance command is executed in the blockchain, the computer that constitutes the blockchain receives the NFT issuance command and executes the NFT issuance process in the blockchain. Issued NFTs are recorded on the blockchain. NFT_ID is given to the NFT issued in the blockchain. Issuance of the initial NFT is performed by the ticket NFT management server 12 or the smart contract 130, for example. The issued initial NFT is stored, for example, at contract address 140 of smart contract 130 .

The ticket NFT management server 12 of the ticket NFT management system 10 acquires the NFT_ID (NFT_ID: A) of the initial NFT. The ticket NFT management server 12 associates the NFT_ID and the ticket data with each other and stores them in the database 13 . As a result, the ticket data is incorporated into the initial NFT. The NFT in which the ticket data is embedded is the ticket NFT101. Also, the ticket data stored in the database 13 becomes the digital ticket 13A.

As described above, the database 13 allows the digital ticket 13A to be referenced by the user recorded in the blockchain 11 as the owner of the ticket NFT 101 (NFT with NFT_ID: A) associated with the digital ticket 13A. are stored in the database 13 as shown in FIG. As a result, the digital ticket 13A is substantially integrated with the ticket NFT 101 and converted into an NFT. The ticket NFT 101 and the digital ticket 13A may be associated with each other, for example, by having the ticket NFT 101 have a URI (Uniform Resource Identifier) indicating the digital ticket 13A stored in the database 13.

The ticket NFT management server 12 generates code data indicating at least the second identification information for identifying the ticket NFT 101 (step S304). The code is, for example, a machine-readable two-dimensional code. The two-dimensional code data is data representing a two-dimensional code pattern or data for generating the pattern. The data for generating the pattern of the two-dimensional code indicates, for example, a URL (Uniform Resource Locator), and the URL indicates, for example, the domain of the ticket NFT management server 12 and the second identification information. The generated two-dimensional code indicates the aforementioned URL.

The second identification information for identifying the ticket NFT101 may be the NFT_ID: A of the ticket NFT101, but here, the ticket number (exchange number) of the digital ticket 13A and the ticket 1 associated with the ticket NFT101 "abcdefg ” is used as the second identification information. That is, the second identification information for identifying the ticket NFT101 is the same as the ticket number (exchange number), which is the first identification number for identifying the ticket 1 .

The ticket NFT management server 12 associates the ticket number "abcdefg" with the NFT_ID: A so that the NFT_ID: A of the ticket NFT101 can be grasped from the ticket number "abcdefg", which is the second identification information of the ticket NFT101. It is saved in the management database 12D of the ticket NFT management server 12 (see FIG. 5). By referring to the management database 12D, the ticket NFT management server 12 can grasp the NFT_ID from the ticket number, which is the second identification information, and can also grasp the ticket number from the NFT_ID.

The ticket NFT management server 12 transmits the generated two-dimensional code data and the ticket number (exchange number) of ticket 1 to which the two-dimensional code should be attached to the ticket issuing server 300 (step S305). When the above processing is completed, the ticket NFT management system 10 transmits a processing completion notice to the ticket reservation web server 400 as necessary (step S306).

The ticket issuing server 300, which has received the two-dimensional code data and the ticket number (exchange number) of the ticket 1 to which the two-dimensional code is to be attached, has the received two-dimensional code data with the received ticket number (exchange number). It is saved in association with the ticket data (step S308). As a result, the ticket issuing server 300 can add the two-dimensional code data to the ticket data received from the ticket reservation web server 400 and store the data.

The ticket data that the issuing device 200 acquires from the ticket issuing server 300 has the two-dimensional code data added as described above. Therefore, the ticket 1 manufactured by printing the ticket data has a two-dimensional code 1A as shown in FIG. 1, and this two-dimensional code 1A has second identification information for identifying the ticket NFT 101. . The two-dimensional code 1A is used by the user to acquire the ticket NFT101.

FIG. 4 shows another example of the ticket 1 issuing procedure (ticket 1 manufacturing method) using the system 500 . In FIG. 4, points that are not particularly described are the same as in the example of FIG. A person (user) who wishes to purchase a ticket 1 performs a ticket reservation operation in the same manner as in step S301. As a result, ticket data for ticket 1 is generated (step S401: ticket reservation processing).

The ticket data including the ticket number (exchange number) is transmitted from the ticket reservation web server 400 to (the ticket NFT management server 12 of) the ticket NFT management system 10 (step S402). The ticket data transmitted to the ticket NFT management system 10 is used for the processing of steps S403 and S404. Steps S403 and S404 are the same as steps S303 and S304 in FIG.

The ticket NFT management server 12 transmits the two-dimensional code data generated in step S404 and the ticket number (exchange number) of ticket 1 to which the two-dimensional code should be attached to the ticket reservation web server 400 (step S405).

The ticket reservation web server 400 adds the received two-dimensional code data to the generated ticket data and saves it. The ticket reservation web server 400 transmits the ticket data including the two-dimensional code data to the ticket issuing server 300 (step S406). The ticket reservation web server 400 outputs the exchange number (first identification information) to issue ticket 1 (step S407). The ticket issuing server 300 stores the ticket data received from the ticket reservation web server 400 (step S408).

The user who has obtained the exchange number visits a store such as a convenience store and has a ticket 1 issued (steps S409 to S412). Steps S409 to S412 are the same as steps S309 to S312 in FIG.

FIG. 5 shows the procedure for the user to obtain the ticket NFT 101 corresponding to ticket 1 using issued ticket 1. When the user acquires the ticket NFT101, the digital ticket 13A is displayed on the display 31 of the user terminal 30 (see FIG. 6). Before the user acquires the ticket NFT 101, the ticket NFT 101 is stored in the contract address 140 or the like of the smart contract 130 (see FIG. 2).

First, the user who obtained the paper ticket 1 causes the user terminal 30 to read the two-dimensional code 1A attached to the ticket 1 (step S501). The user terminal 30 includes a reader such as a camera (not shown) for reading the machine-readable code 1A. By this reading, the user terminal 30 acquires the URL indicated by the code 1A (the domain of the ticket NFT management server 12 and the ticket number (second identification information)).

The user terminal 30 that has acquired the URL executes network access according to the URL (step S502). That is, the user terminal 30 accesses the ticket NFT management server 12 according to the URL and transmits the ticket number “abcdefg”, which is the second identification information, to the management server 12 . Access from the user terminal 30 to the ticket NFT management server 12 is an operation request (owner change request) to change the owner of the ticket NFT 101 corresponding to the ticket 1 to the user. When the user terminal 30 accesses the ticket NFT management server 12 , the user's account (blockchain address) in the blockchain 11 may be transmitted from the user terminal 30 to the ticket NFT management server 12 .

The ticket NFT management server 12 acquires the ticket number "abcdefg", which is the second identification information, from the user terminal 30 through access from the user terminal 30. The ticket NFT management server 12 has a management database 12D shown in FIG. The management server 12 refers to the management database 12</b>D and converts the acquired ticket number “abcdefg” into NFT_ID:A indicating the ticket NFT 101 in the block chain 11 . Note that if the second identification information indicated by the code 1A is the NFT_ID itself, it is not necessary to refer to the management database 12D.

When the ticket NFT management server 12 acquires the NFT_ID: A for identifying the ticket NFT101, the ticket NFT101 indicated by the NFT_ID: A is the target of the owner change operation, and the smart contract is used for the NFT owner change operation. 130 (step S503). When calling, the ticket NFT management server 12 gives the smart contract 130 the NFT_ID: A of the ticket NFT 101 to be operated and the user's blockchain account 110 (blockchain address). The smart contract 130 identifies the ticket NFT101 to be operated by NFT_ID: A of the ticket NFT101. Smart contract 130 also identifies the user who is the new owner of ticket NFT 101 by the user's blockchain account 110 .

The called smart contract 130 executes an operation to change the owner of the identified ticket NFT 101 to be operated to the identified user (step S504). This operation is performed by the smart contract 130 executing a command to send the ticket NFT 101 from the contract address 140 of the smart contract 130 to the user's blockchain address 110 in the blockchain 11 . As a result, the user owns the ticket NFT101 corresponding to the ticket 1. The change of the owner of the ticket NFT101 to the user is recorded in the blockchain 11. The smart contract 130 may notify the ticket NFT management server 12 of the owner change completion notification.

As shown in FIG. 6, the digital ticket associated with the ticket NFT101 is displayed on the user terminal 30 of the user who has become the owner of the ticket NFT101 by the owner change request using the reading of the code 1A as described above. 13A is displayed. The display 31 of the user terminal 30 shown in FIG. 6 displays a ticket NFT display screen 33 showing the digital ticket 13A associated with the ticket NFT101. An application program is installed in the user terminal 30 to display the data 13A associated with the NFT 101 owned by the user. This application program displays the ticket NFT101 and the digital ticket 13A associated with the ticket NFT101. Sending of the aforementioned change of ownership request may be performed by this application program.

As described above, the digital ticket 13A is stored in the database 13. The ticket NFT management server 12 and the database 13 execute processing for displaying the digital ticket 13A on the terminal 30 of the user who has become the owner of the ticket NFT101. In this way, by obtaining the ticket NFT101, the user can use it, such as displaying the digital ticket 13A associated with the ticket NFT101.

MFPs are used to provide content print services as well as other print services, copy services, and facsimile services. MFPs can generally be operated directly by customers visiting the store, but may also be operated by store staff.

Upon receiving an operation by an operator such as a customer (user), the issuing device 200 acquires necessary content data from the content issuing server 300 and issues content 1 by printing the content data. The issuing device 200 is configured to receive an input of a product number. The entry of the product number is performed, for example, by operating a key or by reading a code indicating the product number with a reader included in the multifunction machine.

The issuing device 200 is configured to receive a payment operation for the price of the content 1 and execute payment processing to settle the price before the content 1 is issued. Content 1 is issued after the payment process is completed. A person (user) who intends to purchase the content 1 can pay for the content 1 at a store such as a convenience store, so that the content 1 can be obtained easily. Also, the content NFT101 can be easily obtained by paying for the content 1 at the store.

The content issuing server 300 is connected to the issuing device 200 via the network 15 . The content issuing server 300 is an external device installed at a location separate from the issuing device 200 so that a plurality of issuing devices 200 can be connected.

FIG. 10 shows the procedure for issuing content 1 using the system 500 (method for producing content 1). A person (user) who wishes to purchase the content 1 uses the terminal 30 to confirm the product number described on the content introduction website 600 . The user visits a store such as a convenience store and has Content 1 issued (steps S1001 to S1003, S1010, S1011). In order to issue content 1, the user first inputs a product number to the issuing device 200. FIG. As a result, the issuing device 200 acquires the item number of the content 1 (step S1001). Note that if the display of the issuing device 200 allows selection of the content to be purchased from the list of purchasable content 1, the user selects the content 1 that the user wishes to purchase, and the issuing device 200 displays the content 1. You can get the item number.

The issuing device 200 processes payment for content 1 (step S1002). As a result, the payment for the content 1 is completed. The issuing device 200 acquires the content data after the payment is processed (step S1011). Note that acquisition of content data may be performed before payment processing (step S1002). The issuing device 200 uses the acquired product number (first identification information) to acquire content data. More specifically, the issuing device 200 transmits the item number to the content issuing server 300 (step S1003).

The content issuing server 300 transmits the content data corresponding to the product number to the issuing device 200 (step S1009). The issuing device acquires content data. The acquired content data includes the data of the two-dimensional code 1A. The content data is data for printing the content 1 .

The issuing device 200 prints the content data for printing the content 1 on printing paper and issues the content 1 (step S1011). The printed content 1 has a two-dimensional code 1A as shown in FIG. The two-dimensional code 1A is used, for example, to obtain the content NFT101 associated with the digital content 13A, which is the digitized content 1. FIG.

In order to include the data of the two-dimensional code 1A from the content issuing server 300 to the issuing device 200, the content issuing server 300 transmits the content data of the content 1 to be issued to the content NFT management system 10 (step S1004). Note that the content issuing server 300 has content data of various content items 1 that can be issued in association with product numbers. The content data transmitted to the content NFT management system 10 can be identified from the product number transmitted in step S1003 from the content data of the content 1 to be published transmitted from the issuing device 200 .

Upon receiving the content data, the content NFT management system 10 executes processing for the content NFT 101 (steps S1005 to S1007).

First, in the content NFT management system 10, a process of associating received content data with an NFT (initial NFT) is performed (step S1003: generation of content NFT101). As a result, the content data is incorporated into the initial NFT. An NFT in which content data is incorporated is content NFT101. Also, the content data stored in the database 13 becomes the digital content 13A.

The content NFT management server 12 generates two-dimensional code data indicating at least the second identification information for identifying the content NFT 101 (step S1004). The two-dimensional code indicates a URL (Uniform Resource Locator), and the URL indicates, for example, the domain of the content NFT management server 12 and the second identification information.

The second identification information for identifying the content NFT101 may be NFT_ID: A of the content NFT101, but here, "aaaaa", which is the product number of the digital content 13A and the content 1 associated with the content NFT101, is the second identification information. 2 used as identification information. In other words, the second identification information for identifying content NFT101 is the same as the product number, which is the first identification number for identifying content 1 .

The content NFT management server 12 associates the product number "aaaaa" with the NFT_ID: A so that the NFT_ID: A of the content NFT 101 can be grasped from the product number "aaaaa" that is the second identification information of the content NFT 101, It is saved in the management database 12D of the content NFT management server 12 (see FIG. 12). By referring to the management database 12D, the content NFT management server 12 can grasp the NFT_ID from the product number, which is the second identification information, and can also grasp the product number from the NFT_ID.

The content NFT management server 12 transmits the generated two-dimensional code data and the product number of the content 1 to which the two-dimensional code should be attached to the content issuing server 300 (step S1007).

The content issuing server 300, which has received the two-dimensional code data and the product number of the content 1 to which the two-dimensional code is to be attached, stores the received two-dimensional code data in association with the content data having the received product number. (Step S1008). Thereby, the content issuing server 300 can add the two-dimensional code data to the content data and save it.

The content issuing server 300 transmits content data including two-dimensional code data to the issuing device 200 (step S1009), and the issuing device 200 receives the content data (step S1010). The content 1 produced by printing this content data has a two-dimensional code 1A, as shown in FIG. 7, and this two-dimensional code 1A has second identification information for identifying the content NFT101. The two-dimensional code 1A is used by the user to acquire the content NFT101.

FIG. 11 shows another example of the content 1 issuing procedure (content 1 manufacturing method) using the system 500 . In FIG. 11, points not particularly described are the same as in the example of FIG.

In FIG. 11, before the content issuing server 300 receives a content data request (step S1003) from the issuing device 200, the processing of steps S1005 and S1006 is executed.

The content NFT management system 10 receives content data in advance from the content issuing server 300, executes steps S1005 and S1006, and converts the content data to NFT.

Then, when the content NFT management system 10 receives the product number (first identification information) of the content 1 to be issued from the issuing device 200 via the content issuing server 300, the product number (first identification number) and Two-dimensional code data indicating the same product number (second identification information) is transmitted to the content issuing server 300 (step S1007). Subsequent processing is performed in the same manner as in FIG. In the case of the processing of FIG. 11, since the content data is converted to NFT in advance, the content 1 can be quickly issued.

FIG. 12 shows a procedure for the user to acquire the content NFT 101 corresponding to the content 1 using the published content 1. Steps S1201, S1202, S1203, and S1204 shown in FIG. 12 are substantially the same processes as steps S501, S502, S503, and S504 shown in FIG.

As shown in FIG. 13, digital content 13A associated with content NFT101 is displayed on the user terminal 30 of the user who has become the owner of content NFT101 by means of an owner change request using reading of code 1A. be. As shown in FIG. 13, the display 31 of the user terminal 30 displays a content NFT display screen 33 showing the digital content 13A associated with the content NFT101. In this way, by obtaining the content NFT101, the user can use it, such as displaying the digital content 13A associated with the content NFT101.

The present invention is not limited to the above embodiments, and various modifications are possible.
