Digital asset identity authentication and authorization management system based on DID and programmable object

By using three-layer DID digital identity technology and an improved VF2 object encapsulation algorithm and TabPFN network, a digital asset identity authentication and authorization management system is constructed. This solves the problems of inconsistent identity binding and non-compliant authorization policy judgment in the digital asset management system, and achieves highly reliable, secure and traceable digital asset management.

AI Technical Summary

Technical Problem

Existing digital asset management systems lack decentralized identity binding mechanisms, making it difficult to maintain consistency in asset ownership, usage, and authorization request relationships across platforms. This leads to issues such as impersonation, identity mismatch, and unclear authorization sources. Furthermore, the authorization policy determination methods lack constraints on DID link consistency and programmable object rules, making it difficult to generate trustworthy, compliant, and auditable authorization policies.

Method used

Employing three-layer DID digital identity technology, an improved VF2 object encapsulation algorithm, and an improved dual-constraint TabPFN network, a digital asset identity authentication and authorization management system is constructed. This system includes modules for digital asset data access, DID identity generation and binding, programmable object construction, identity authentication, authorization policy management, and secure communication and authorization execution. This achieves high identity credibility, strong compliance in authorization judgment, high security in digital asset circulation, and traceability of the authorization process.

Benefits of technology

It improves the integrity of user data asset management, the credibility of three-layer DID digital identity binding, the security of user asset account management, and the traceability of the authorization management process, ensuring the accuracy and compliance of authorization policy judgment and enhancing the security and credibility of digital asset circulation.
