2. Hardware Configuration FIG. 2 is a diagram showing an example of the hardware configuration of the server device 100. The server device 100 includes a control section 210, a storage section 220, and a communication section 230 as a hardware configuration. The control unit 210 is a CPU (Central Processing Unit) or the like, and controls the entire server device 100. The storage unit 220 is a HDD (Hard Disk Drive), a ROM (Read Only Memory), a RAM (Random Access Memory), an SSD (Solid State Drive), or any combination thereof, and the program and control unit 210 Stores data etc. used when executing processing based on a program. The functions of the server device 100 are realized by the control unit 210 executing processing based on the program stored in the storage unit 220. The communication unit 230 is a NIC (Network Interface Card) or the like, connects the server device 100 to the network 150, and controls communication with other devices. Storage unit 220 is an example of a storage medium.

3. Information processing (processing overview)
The control unit 210 of the server device 100 registers the content and the rights information regarding the intellectual property of the content in the blockchain system 140 in association with each other. In this embodiment, the content is a non-fungible token (NFT). Note that among non-fungible tokens (NFTs), it is better to use a token called a solebound token (SBT) that can only be moved by the issuer. By using SBT, wallet owners cannot unilaterally transfer rights information related to content intellectual property to other wallet owners without permission, and risks due to operational errors and hacking can be avoided. Examples of content include NFTs of characters from comics and/or movies. As the rights information regarding the intellectual property of the content, there is, for example, information on the copyright regarding the content.

When the control unit 210 of the server device 100 receives an application for the Nth (N is a natural number of 2 or more) creation related to the content, the control unit 210 determines whether to permit the Nth creation to all related rights holders before N. If all related right holders prior to N approve the Nth creation, the Nth creation will be approved for the application. For example, when the control unit 210 receives an application regarding the tertiary creation of content, the control unit 210 requests all related rights holders prior to the tertiary creation, such as the primary creator and the secondary creator, to submit the tertiary creation. Issues an inquiry as to whether or not permission is granted. For example, the control unit 210 displays a screen including an input area for inputting whether or not to make an inquiry on the management screen of all related rights holders prior to the tertiary creation, such as the primary creator and the secondary creator. let For example, if the control unit 210 receives responses from all rights holders, such as primary creators and secondary creators, via the input area to the effect that the tertiary creation is permitted, the control unit 210 may request that the tertiary creation applicant 3rd creation is permitted. For example, the control unit 210 displays a screen containing information to the effect that tertiary creation is permitted on the management screen of the applicant for tertiary creation, and also displays information such as how to register the content of tertiary creation. Display it on the screen.

As another example, when the control unit 210 of the server device 100 receives an application for the Nth (N is a natural number of 2 or more) creation regarding the content, the control unit 210 sends the Nth creation to the right holder regarding the (N-1) next creation. An inquiry as to whether or not to allow the creation is issued through a smart contract that records it on the blockchain, and (N-1) the rights holder regarding the next creation signs the smart contract with his or her own wallet to allow the next creation. If so, permission will be granted for the Nth creation of the application. For example, when the control unit 210 receives an application regarding tertiary creation of content, it issues an inquiry to the right holder of the secondary creation immediately before the tertiary creation as to whether or not to permit the tertiary creation. do. For example, the control unit 210 causes a screen including an input area for inputting whether or not to make an inquiry to be displayed on a management screen or the like of the rights holder of the secondary creation. For example, when the control unit 210 receives a response from the secondary creator via the input area to the effect that tertiary creation is permitted, the control unit 210 allows the tertiary creation applicant to perform tertiary creation. For example, the control unit 210 displays a screen containing information to the effect that tertiary creation is permitted on the management screen of the applicant for tertiary creation, and also displays information such as how to register the content of tertiary creation. Display it on the screen.

Further, the control unit 210 of the server device 100 distributes the sales profits of the content related to the Nth creation to all the related rights holders before N. The control unit 210 distributes profits by transferring a predetermined digital currency to the corresponding wallet by executing a smart contract recorded on the blockchain, and further transfers the profits deposited to the wallet to the virtual currency exchange. Use it and exchange it for fiat currency. Then, the control unit 210 may distribute profits by transferring legal currency to a corresponding account.

The control unit 210 of the server device 100 associates information regarding the N-creation, content and NFT of the content, and rights information regarding the intellectual property of the content and registers them in the blockchain system. Even if the content NFT is not created using a specified smart contract, it is highly versatile because it is possible to link all NFT information compatible with multiple blockchains. For example, when a tertiary creation is created, the control unit 210 may collect information regarding the nth creation, such as who authorized it, who gave the permission, what the content was created based on, etc. It is registered in the blockchain system 140 in association with the above-mentioned rights information regarding the content and the intellectual property of the content.

The control unit 210 of the server device 100 controls to output information related to the N-th creation of content registered in the blockchain system 140 to a screen or the like in response to a request from a client device or the like.

FIG. 3 is a diagram illustrating an example of services of the information processing system 1000.
Step (1)
A right holder who has IP rights or serves as a contact person sends a document certifying IP rights to information processing system 1000. After the data is received by the information processing system 1000, the system operator checks the IP content and, if there are no problems, instructs the IP to be registered and to create a wallet address for the IP right holder. Based on this instruction, the information processing system 1000 creates a wallet address for the IP right holder, and registers the IP in the blockchain based on the corresponding IP and wallet address.

Step (2)
A creator applies to the information processing system 1000 for derivative creation rights (permission for derivative creation) using IP in order to use IP rights owned by IP rights holders. When the IP rights holder approves this application, the information processing system 1000 issues an electronic signature and confirms that the rights have been granted. The right grant is simultaneously written to the blockchain by the information processing system 1000.

Step (3)
An NFT work created by a creator and granted with IP rights is created using an information processing system 1000, and simultaneously registered on the blockchain. At the same time, the IP registration information, creator information, IP right holder information, and NFT work information to which IP rights have been granted are disclosed on the application screen of the information processing system 1000.

Step (4)
NFT works created with the information processing system 1000 are displayed on marketplaces and Dapps tools that have the same standards, and a certification mark is attached. NFT users check the blockchain information and certification mark on those marketplaces, confirm that the NFT is licensed, and purchase it.

Step (5)
Royalties etc. will be deposited after the NFT is sold.

Step (6)
The information processing system 1000 distributes and remits royalties and other payments generated to IP rights holders, creators, and other parties at the rate written in the smart contract.
