Abstract

The invention discloses a multi-dimensional digital identity authentication system based on a block chain, and relates to the technical field of block chains. The system comprises: a block chain layerused for storing and anchoring a DID document and other data needing distributed storage content; a decentralized identity analysis adaptation service layer which is used for providing a unified DIDdocument analysis service for the block chain layer, and the service can be connected with other application chains at the same time to carry out cross-chain application; a trusted exchange layer which is used for obtaining a DID document through an identity on a user agent registration chain, applying for various verifiable certificates to a certificate issuer by depending on the DID document, and finally providing the DID and the verifiable certificates to a verifier to complete a verification process; and an application layer which is used for constructing a web, wherein an application of the mobile client is provided for a terminal user to use. The system supports cross-chain and cross-platform interoperation, and can be expanded in various different modes.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a multi-dimensional digital identity authentication system based on block chains. Background technique [0002] In the existing technology, the entity object (that is, the person or thing with the identity ID on the chain) applies for identity certificates from several organizations; then, the user agent (usually an authoritative and trusted organization such as a government department) generates an ID on the chain for the user and provides KYC service. After the authentication is completed, the entity can choose to authorize its various data to several organizations; at this time, the organization using the data can choose to purchase the services of some credential verifiers, who can assist multiple parties in whether the data of the entity has been tampered with, whether Certified by the credential issuer (referring to the organization or individual that issues a...
