The patent filed by Rakuten Group Inc. describes an information processing system that involves the issuance of non-fungible tokens (NFTs) linked to content data. The system includes several components and processes for generating metadata, acquiring hash values, and recording token data in a blockchain.
The system begins by acquiring a hash value based on a key that contains content data linked to an NFT. This hash value is used to generate metadata for the content. The metadata includes an electronic signature generated using the hash value and a predetermined secret key, as well as a resource identifier that is referenced when acquiring the content data.
A metadata identifier is then acquired, which uniquely indicates the metadata. This metadata identifier is used to issue a non-fungible token that is linked to both the metadata and the content. The token data, including the metadata identifier, is recorded in a blockchain.
The system also includes additional features and functionalities. For example, the resource identifier may include a content identifier that uniquely indicates the content. The system can generate the content identifier according to a content identifier generation procedure, regardless of whether the content data is added to a content-oriented data management system.
The system can also manage the content data using location-oriented data management and add it to the content-oriented data management system using the content identifier generated by the system.
Furthermore, the system can add the metadata to the content-oriented data management system and acquire an identifier issued by the system as the metadata identifier when the metadata is added.
The system is capable of issuing multiple non-fungible tokens linked to the same combination of metadata and content by recording multiple pieces of token data in the blockchain, each with different additional data.
The metadata generated by the system can include various types of information, such as distribution of value in a transaction, provider information, performer information, credit information, group information, date/time information, location information, event information, processing information for user terminals, and maximum number of issuable tokens for the content.
Overall, the information processing system described in the patent enables the issuance of non-fungible tokens linked to content data, with the metadata and token data recorded in a blockchain.
