Abstract
A token management system includes a generation unit that generates a non-fungible token associated with a product identifier in a distributed ledger, a management unit that associates the non-fungible token with a first public key, and a second public key for licensing processing in the distributed ledge, and a transfer unit that performs transaction processing of changing the first public key associated with the non-fungible token on the basis of a first private key is realized.
Claims6
A token management system comprising:
- an administrator terminal includes a processor and a memory performs:
- generating a non-fungible token associated with a product identifier in a distributed ledger, associating the non-fungible token with a first public key as an owner identifier, and a second public key for licensing processing, in the distributed ledger, and transaction processing in the distributed ledger of changing a first public key as an owner identifier of a transfer source, which identifier is associated with the non-fungible token, into a first public key as an owner identifier of a transfer destination on a basis of a first private key of the transfer source;
- a licensee terminal includes a processor performs transaction processing in the distributed ledger of changing the first public key as the owner identifier of the transfer source, which identifier is associated with the non-fungible token, into the first public key as the owner identifier of the transfer destination on the basis of the first private key of the transfer source;
- and wherein the processor and the memory included by the administrator terminal registers the second public key as metadata of the non-fungible token on a basis of a data description language representing at least one of a numerical value, a character string, a truth value, an array, and an object.

A token management method comprising a processor and a memory:
- causing the processor of an administrator terminal to execute generating a non-fungible token associated with a product identifier in a distributed ledger, associating the non-fungible token with a first public key as an owner identifier, and a second public key for licensing processing, in the distributed ledger, and transaction processing in the distributed ledger of changing a first public key as an owner identifier of a transfer source, which identifier is associated with the non-fungible token, into a first public key as an owner identifier of a transfer destination on a basis of a first private key of the transfer source;
- causing a processor of a licensee terminal to execute transaction processing in the distributed ledger of changing the first public key as the owner identifier of the transfer source, which identifier is associated with the non-fungible token, into the first public key as the owner identifier of the transfer destination on the basis of the first private key of the transfer source;
- and wherein the processor and the memory included by the administrator terminal registers the second public key as metadata of the non-fungible token on a basis of a data description language representing at least one of a numerical value, a character string, a truth value, an array, and an object.
