Application: Token management method, end-user management apparatus, and token processing apparatus (Patent ID: US20230370266A1)
The patent filed by Hitachi Ltd. describes a token management system that records the consent of an end user who entrusts the operation of a token to a blockchain network participant organization. The system includes various units such as token registration, user management, token management, policy management, and life cycle management. The method involves registering test results, electronic signatures, and hash values of token programs as confirmation evidence, recording user consent to entrust token operation to a virtual organization, and managing policies for token deployment. The system ensures that deployment requests for tokens meet policy definitions before actual deployment.
Furthermore, the patent also describes an end-user management apparatus connected to multiple token processing apparatuses for deploying tokens. The apparatus includes a user management unit that registers user information and agent details in a distributed ledger format. Additionally, a token management unit handles token issuance requests and updates policy definitions for token deployment. The apparatus ensures that user consent is obtained before issuing or deploying tokens, and the information is stored in a distributed ledger format shared among the token processing apparatuses. The system also includes audit units to verify the authenticity of deployment policies by comparing user agents with organizations requiring signatures for deployment.
