<System overview>
FIG. 1 is a diagram showing an example of the overall configuration of an information processing system according to an embodiment of the present invention. The information processing 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 a communication network. The communication network is, for example, the Internet, and is constructed using a public telephone line network, a mobile phone line network, a wireless communication channel, Ethernet (registered trademark), and the like.

The user terminal 1 and the management server 2 are also communicably connected to the first and second blockchain networks 3 and 4. The first and second blockchain networks 3 and 4 are 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 to make 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 first and second blockchain networks 3 and 4 can be constructed using Ethereum, for example.

Tokens (Ethereum tokens) that can be issued by the first and second blockchain networks 3 and 4 such as Ethereum include fungible tokens and non-fungible tokens: NFT). 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 blockchain networks. NFT transaction history is recorded on a blockchain network. The distributed ledger of the blockchain network also records the owner and ownership history of the NFT.

<Management server>
The management server 2 may be a general-purpose computer such as a workstation or a personal computer, or may be logically realized by cloud computing.

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 3, 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 device 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. This is realized as part of the storage area provided by 203.

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 contract information registration section 211, an NFT issuing section 212, a distribution section 213, a gift reception section 214, an NFT transmission section 215, a distribution processing section 216, and a content storage section 231.

The content storage unit 231 stores digital content. Digital content can be, for example, music, video, images, etc. The content storage unit 231 can store digital content in a file format, for example.

The contract information registration unit 211 registers contract information. The contract information registration unit 211 registers contract information in the distributed ledger managed by the first blockchain network 3. The contract information includes, for example, contract details related to permission of copyright or copyright-related rights regarding digital content. Further, contract information can be managed in association with an e-mail address. This e-mail address shall be authenticated.

The NFT issuing unit 212 issues NFTs on the second blockchain network 4. NFTs are issued in association with digital content. The NFT issuing unit 212 can set information that specifies contract information regarding the digital content in the metadata of the NFT.

The NFT may be issued in association with a partial content extracted from a portion of the digital content. In this case, the NFT issuing unit 212 may extract a part of the digital content to be distributed (for example, it may divide the digital content, or it may extract partial content within a range where overlap is allowed). ), it is possible to issue an NFT in association with the extracted portion (partial content). The NFT issuing unit 212 can register the extracted partial content in the content storage unit 231 and set information (for example, URL, etc.) that identifies the stored partial content in the metadata of the NFT. .

The NFT issuing unit 212 also generates a non-fungible non-fungible whose metadata includes information identifying the copyright holder or neighboring rights holder of the track, corresponding to at least one of the plurality of tracks for generating digital content. It is also possible to issue tokens. Here, too, the first blockchain network 3 manages the contract information regarding the permission of the copyright or copyright related rights related to the track, and information specifying the contract information can be set in the metadata of the NFT. A track can be, for example, a drum part, guitar part, bass part, piano part, vocal part, etc. of a song or sound source. Further, the track can be, for example, one frame of video (which may be a still image or a moving image). Further, the track may be divided in units of measures or units of time.

The distribution unit 213 can distribute digital content. The distribution unit 213 can distribute digital content (music, videos, images), for example, by streaming.

The gift reception unit 214 can receive gifts from viewers (user terminals 1) when digital content is distributed. The gift can be, for example, a tip. Further, an image or the like to be displayed superimposed on distributed digital content may be given as a gift.

The NFT transmitter 215 gives NFT to the viewer who provided the gift. The NFT sending unit 215 can send the NFT issued by the NFT issuing unit 212 to the wallet of the viewer who provided the gift.

Note that the NFT issuing unit 212 may issue an NFT in response to a gift being provided, or may issue a predetermined number of NFTs in advance.

The NFT transmitter 215 can also determine the NFT to transmit to the viewer depending on the value of the gift. For example, a rarity can be set for each NFT, and the higher the value of the gift, the higher the rarity of the NFT assigned.

Further, the NFT transmitter 215 may select the gift by lottery. In this case, the NFT transmitter 215 can perform a lottery with a probability according to the value and rarity of the gift, for example.

The distribution processing unit 216 distributes the amount corresponding to the consideration for the sale of the NFT or the usage fee for the copyright or copyright related rights for the use of the digital content corresponding to the NFT to the copyright holder set in the metadata of the NFT. Alternatively, payment may be made to the owner of related rights. The distribution processing unit 216 also distributes at least a portion of the usage fee for the copyright or copyright-related rights related to the track when the owner of the NFT uses the track to the copyright holder indicated by the information set in the NFT. Alternatively, the payment may be made to the holder of related rights.

<Operation>
The operation of the information processing system of this embodiment will be described below.

FIG. 4 is a diagram illustrating the process of issuing an NFT linked to a contract. The management server 2 registers the given contract information in the first blockchain network 3 (S301), and specifies the contract information in the metadata of the NFT when issuing the NFT in the second blockchain network 4. Information is set (S302).

FIG. 5 is a diagram illustrating the process of issuing NFTs according to tipped coins. When the management server 2 distributes the digital content (S321) and accepts tipped coins from viewers (users) during the distribution (S322), the management server 2 stores partial content extracted from a portion of the digital content in the wallet of the user who tipped the coins. The corresponding NFT is transmitted (S323).

FIG. 6 is a diagram illustrating processing related to the distribution of usage fees for copyrights or copyright-related rights related to tracks. The management server 2 issues an NFT corresponding to a portion of a plurality of tracks for generating digital content (S341), and when the track is used by a user (for example, when it is used for producing UGC), A usage fee for copyright or copyright-related rights related to the use of the track is collected (S342), and a portion of the collected copyright or copyright-related rights fee is transferred to the copyright owner or copyright-related rights set in the NFT. The process can be executed to pay the person (S343).

Although the present embodiment has been described above, the above embodiment is for facilitating understanding of the present invention, and is not for construing the present invention in a limited manner.
