<System overview>
FIG. 1 is a diagram showing an example of the overall configuration of a distribution system according to an embodiment of the present invention. The distribution system of this embodiment is configured to include a management server 2. The management server 2 is communicably connected to the user terminal 1 via the communication network 5 . The communication network 5 is, for example, the Internet, and is constructed using a public telephone line network, a mobile phone line network, a wireless communication path, Ethernet (registered trademark), or the like.

The management server 2 is also communicably connected to the blockchain network 3. The blockchain network 3 is composed of a plurality of nodes (computers) and can manage ledger data in a distributed manner. Distributed ledgers are managed using a so-called blockchain mechanism that makes them difficult to tamper with. Note that a detailed explanation of the blockchain-based distributed ledger management mechanism will be omitted here as a general one will be adopted. The blockchain network 3 can be constructed using Ethereum, for example.

Tokens (Ethereum tokens) that can be issued by blockchain networks such as Ethereum include fungible tokens and non-fungible tokens (NFTs). NFTs are non-fungible tokens, unlike fungible tokens. NFTs can have unique value that distinguishes them from other NFTs. For this reason, NFTs have a unique identifier (NFT-ID) to enable them to be distinguished from other NFTs. NFT is, for example, a token issued according to the ERC (Ethereum Request for Comments) 721 standard. NFTs that comply with the ERC721 standard are also called NFT-721 tokens. In this embodiment, as an example, it is assumed that the NFT is an NFT-721 token. NFTs, like fungible tokens, can be traded on the blockchain network 3. NFT transaction history is recorded in the blockchain network 3. In the distributed ledger of the blockchain network 3, the owner and ownership history of the NFT are also recorded.

The distribution system of this embodiment issues the right to listen to music using NFT. A user can listen to music linked to NFT by purchasing NFT linked to music and proving that he or she owns the NFT. Furthermore, in this embodiment, it is assumed that it is possible to listen to music through a so-called subscription service, and while users who participate in the subscription service can listen to music, users who participate in the subscription service Users who do not own the NFT cannot view the music, but owners of NFTs related to viewing rights can view the music.

The user terminal 1 is a computer used by a user, such as a smartphone, a tablet computer, or a personal computer.

The management server 2 is a computer that performs various types of management, and may be a general-purpose computer such as a workstation or a personal computer, or may be logically realized by cloud computing.

<Management server>
FIG. 2 is a diagram showing an example of the hardware configuration of the management server 2. As shown in FIG. Note that the illustrated configuration is an example, and other configurations may be used. The management server 2 includes a CPU 201, a memory 202, a storage device 203, a communication interface 204, an input device 205, and an output device 206. The storage device 203 stores various data and programs, and is, for example, a hard disk drive, solid state drive, flash memory, or the like. The communication interface 204 is an interface for connecting to the communication network 5, and includes, for example, an adapter for connecting to Ethernet (registered trademark), a modem for connecting to a public telephone line network, and a wireless communication device for performing wireless communication. , a USB (Universal Serial Bus) connector for serial communication, an RS232C connector, etc. The input device 205 is, for example, a keyboard, mouse, touch panel, button, microphone, or the like for inputting data. The output device 206 outputs data, such as a display, printer, or speaker. Note that each functional unit of the management server 2, which will be described later, is realized by the CPU 201 reading a program stored in the storage device 203 into the memory 202 and executing it, and each storage unit of the management server 2 is implemented by the memory 202 and the storage device 203. It is realized as part of the storage area provided by.

FIG. 3 is a diagram showing an example of the software configuration of the management server 2. As shown in FIG. The management server 2 includes a sales department 211 , an issuing department 212 , an authentication section 213 , a distribution section 214 , a music storage section 231 , a status storage section 232 , and a distribution user storage section 233 .

The music storage unit 231 stores audio data (music data) for reproducing music. The music data may be in any format, such as PCM, WAV, AIFF, MP3, or AAC. Music data may be stored as a file in a file system, or as a record in an object database or a relational database. The music storage unit 231 can store music data in association with a music ID that specifies a music piece.

The status storage unit 232 manages whether or not an NFT has been issued. In this embodiment, the right to issue the NFT can be sold before the NFT is issued. The state storage unit 232 associates a user ID indicating a user who has the right to issue an NFT, a song ID that specifies a song associated with the NFT, and an NFT conversion flag indicating whether or not the NFT has been issued. Can be memorized.

The distribution user storage unit 233 manages users who can receive music distribution. The distribution user storage unit 233 manages users participating in the subscription service. The distribution user storage unit 233 can store, for example, a user ID indicating a user participating in a subscription. The distribution user storage unit 233 may store, for example, the amount (monthly amount) of the subscription service in association with the user ID.

The sales department 211 sells the right to issue NFTs linked to music data. The sales department 211 can perform sales using a well-known method. The sales department 211 acquires a song ID indicating the song to which the rights have been sold and a user ID indicating the user to whom the rights are sold, and stores the obtained user ID and song ID, and a “fake” NFT conversion flag. can be registered in the state storage unit 232 in association with each other.

The issuing unit 212 issues an NFT linked to music data. The issuing unit 212 receives a request specifying a song ID from the user terminal 1, and if the user ID indicating the user of the user terminal 1 and the NFT conversion flag corresponding to the song ID specified in the request are false, the issuer 212 prints the song. An NFT with the ID set as metadata is issued (minted) on the blockchain network 3. Thereby, the issuing unit 212 can mint NFTs that have not been issued. Minting of NFTs can be performed, for example, by calling a smart contract deployed in the blockchain network 3. The issuing unit 212 updates the NFT conversion flag corresponding to the song ID and user ID that issued the NFT to "true".

Authentication unit 213 authenticates the user. The authentication unit 213 can authenticate that the owner of the NFT is the user of the user terminal 1. The authentication unit 213 determines whether the owner of the NFT is a user and is associated with the song ID set in the request (a user ID indicating the user and a song ID are set in the metadata). Authentication can be performed by The authentication unit 213 can authenticate the owner of the NFT using a blockchain mechanism.

The authentication unit 213 can also authenticate participation in the subscription service, for example, based on whether the user ID is registered in the distribution user storage unit 233. Authentication of participation in a subscription service can also be performed using other known methods.

The distribution unit 214 distributes music data to users. The distribution unit 214 distributes music data corresponding to the requested song ID when authentication by the authentication unit 213 is successful. The distribution unit 214 can distribute music data by streaming, for example.

As a result, the distribution unit 214 distributes the music data of the song to the users participating in the subscription service, and the distribution unit 214 also distributes the music data of the song to the users who are participating in the subscription service. The music data of the song can also be distributed even if it is proven that the person has the following.

<Operation>
FIG. 4 is a diagram illustrating the music sales process in the distribution system of this embodiment.

The management server 2 sells a song to a user (S301), and registers the song ID indicating the sold song, the user ID indicating the user, and a "fake" NFT conversion flag in the state storage unit 232 in association with each other. (S302).

When the management server 2 receives a request for a song to be minted from a user (S303), there is an NFT conversion flag corresponding to the user ID indicating the user and the song ID indicating the requested song, and the NFT conversion flag is " If it is "false" (S304: NO), the NFT with the song ID set as metadata is minted and sent to the user's wallet (S305).

FIG. 5 is a diagram illustrating the music distribution process in the distribution system of this embodiment.

When the management server 2 receives a song request from a user (S321), if the user has subscribed (S322: YES), the management server 2 sends a request to the user terminal 1 corresponding to the specified song ID. The music data to be played is distributed (S323).

If the user has not subscribed (S322: NO), the management server 2 determines that an NFT owned by the user exists (S324: YES) and that the music ID related to the request is set in the NFT. If so (S325: YES), the process advances to step S323, and the music data can be distributed.
