[0011] <System Overview> 1 is a diagram showing an example of the overall configuration of an information processing system according to one 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 a user terminal 1 via a communication network. The communication network is, for example, the Internet, and is constructed using a public telephone network, a mobile phone network, a wireless communication path, Ethernet (registered trademark), or the like.

[0012] The user terminal 1 and management server 2 are also communicatively connected to first and second blockchain networks 3 and 4. The first and second blockchain networks 3 and 4 are composed of multiple nodes (computers) and can manage ledger data in a distributed manner. The distributed ledger is managed using a so-called blockchain mechanism to make it difficult to tamper with. Note that a general distributed ledger management mechanism using blockchain is adopted, so a detailed explanation will be omitted here. The first and second blockchain networks 3 and 4 can be constructed using, for example, Ethereum.

[0013] 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 (Non-Fungible Tokens: NFTs). Unlike fungible tokens, NFTs are tokens that are not fungible. NFTs can have unique value that distinguishes them from other NFTs. For this reason, NFTs have a unique identifier (NFT-ID) that enables them to be distinguished from other NFTs. NFTs are tokens issued in accordance with, for example, the Ethereum Request for Comments (ERC) 721 standard. NFTs that comply with the ERC 721 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. The transaction history of NFTs is recorded on the blockchain network. The distributed ledger of the blockchain network also records the owner and ownership history of the NFT.

[0014] <Administration 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.

[0015] FIG. 2 is a diagram illustrating an example of the hardware configuration of the management server 2. Note that the illustrated configuration is an example, and other configurations may also 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, a solid state drive, or a flash memory. The communication interface 204 is an interface for connecting to the communication network 3, and is, for example, an adapter for connecting to Ethernet (registered trademark), a modem for connecting to a public telephone network, a wireless communication device for wireless communication, a USB (Universal Serial Bus) connector or an RS232C connector for serial communication, etc. The input device 205 is used to input data, and is, for example, a keyboard, a mouse, a touch panel, a button, a microphone, etc. The output device 206 is used to output data, and is, for example, a display, a printer, a speaker, etc. Each functional unit of the management server device 2 described below 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 realized as part of the storage area provided by the memory 202 and the storage device 203.

[0016] 3 is a diagram showing an example of the software configuration of the management server 2. The management server 2 includes a contract information registration unit 211, an NFT issuing unit 212, a distribution unit 213, a gift receiving unit 214, an NFT sending unit 215, a distribution processing unit 216, and a content storage unit 231.

[0017] The content storage unit 231 stores digital content. The digital content can be, for example, music, video, images, etc. The content storage unit 231 can store the digital content in, for example, a file format.

[0018] The contract information registration unit 211 registers contract information. The contract information registration unit 211 registers the contract information in a distributed ledger managed by the first blockchain network 3. The contract information includes, for example, contract details related to the licensing of copyright or neighboring rights for digital content. In addition, the contract information may be managed in association with an email address. This email address is to be authenticated.

[0019] The NFT issuing unit 212 issues an NFT on the second blockchain network 4. The NFT is issued in association with digital content. The NFT issuing unit 212 can set information specifying contract information related to the digital content in the metadata of the NFT.

[0020] An NFT may be issued in association with partial content extracted from a portion of digital content. In this case, the NFT issuing unit 212 extracts a portion of the digital content to be distributed (for example, the digital content may be divided, or partial content may be extracted that allows overlapping), and issues 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 identifying the stored partial content (for example, a URL) in the metadata of the NFT.

[0021] The NFT issuing unit 212 can also issue a non-fungible token corresponding to at least one of a plurality of tracks for generating digital content, with metadata containing information identifying the copyright holder or neighboring rights holder of the track. In this case, contract information regarding the licensing of copyright or neighboring rights for the track is managed on the first blockchain network 3, and information identifying 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, or vocal part of a song or sound source. A track can also be, for example, a single frame of video (which can be a still image or a video). A track can also be divided into bars or time units.

[0022] The distribution unit 213 can distribute digital content. The distribution unit 213 can distribute digital content (music, video, or images) by streaming, for example.

[0023] The gift receiving unit 214 can receive gifts from viewers (user terminals 1) when digital content is distributed. The gift can be, for example, a tip. Alternatively, the gift can be an image superimposed on the distributed digital content.

[0024] The NFT sending unit 215 grants an 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.

[0025] The NFT issuing unit 212 may issue an NFT in response to the provision of a gift, or may issue a predetermined number of NFTs in advance.

[0026] The NFT sending unit 215 can also determine the NFT to send 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.

[0027] The NFT transmitting unit 215 may also select a gift by lottery. In this case, the NFT transmitting unit 215 may conduct the lottery with a probability according to the value and rarity of the gift, for example.

[0028] The distribution processing unit 216 can perform processing to pay an amount corresponding to the consideration for the sale of the NFT or a royalty for the copyright or neighboring rights related to the use of the digital content corresponding to the NFT to the copyright holder or neighboring rights holder set in the metadata of the NFT. The distribution processing unit 216 can also pay at least a portion of the royalty for the copyright or neighboring rights related to the track when the NFT owner uses the track to the copyright holder or neighboring rights holder indicated by the information set in the NFT.

[0029] <Operation> The operation of the information processing system of this embodiment will be described below.

[0030] 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 when issuing the NFT on the second blockchain network 4, sets information identifying the contract information in the metadata of the NFT (S302).

[0031] 5 is a diagram illustrating the process of issuing an NFT in response to a tip. The management server 2 distributes digital content (S321), and upon receiving a tip from a viewer (user) during the distribution (S322), sends an NFT corresponding to partial content extracted from the digital content to the wallet of the user who made the tip (S323).

[0032] 6 is a diagram illustrating the process for distributing royalties for copyright or neighboring rights related to tracks. The management server 2 issues NFTs corresponding to some of the tracks used to generate digital content (S341), and when the tracks are used by users (for example, when used to create UGC), it collects royalties for copyright or neighboring rights related to the use of the tracks (S342), and can execute processing to pay a portion of the collected royalties for copyright or neighboring rights to the copyright holder or neighboring rights holder set in the NFT (S343).

[0033] Although the present embodiment has been described above, the above embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and equivalents thereof are also included in the present invention. [Explanation of symbols]
