Embodiment Construction

[0091] A digital certificate is a file that is digitally signed by an identity certification authority and contains user identity content information (usually the user's public key, name, identity code, etc.). It is an authoritative electronic document that can provide identity verification on the Internet. People can communicate on the Internet, for example, in sending secure e-mails, visiting secure sites, online securities transactions, online bidding procurement, online office, online insurance In secure electronic transaction processing and secure electronic transaction activities such as online taxation, online signing and online banking, use it to prove your identity and identify the identity of the other party.

Abstract

One or more embodiments of this specification provide a method and device for authenticating and verifying user identity content information. The authentication method for user identity content information includes: obtaining multiple pieces of user identity content information; Constructing a Merkle tree for each identity content information, the leaf node of the Merkle tree is generated based on the encoding of the user's identity content information; sending multiple identity content information of the user and the leaf node to the storage terminal The corresponding relationship of the user's multiple identity content information, the Merkle certificate of the leaf node corresponding to the user's multiple identity content information on the Merkle tree constructed based on the user's multiple identity content information, and the user's multiple identity content information The root value of the constructed Merkle tree. The above-mentioned storage terminal may include one or more of the client of the user, the server of the certification authority, or the distributed database of the block chain.

Description

technical field [0001] This description relates to the technical field of network communication, and in particular to methods and devices for authentication and verification of user identity content information. Background technique [0002] When the CA certification authority generates a digital certificate, it usually puts all the identity information of the user, including the name, identity number (the social unified credit code or organization verification code for the institutional user, and the ID number for the individual user), address, etc., in plain text format. , or the encoding format (such as base 64) that can be decoded in reverse is stored in the digital certificate. When the above digital certificate is verified, all the identity information contained in the above digital certificate can be obtained by the verification agency, and all the above identities Disclosure of information is unnecessary in most cases. There is still a lack of a digital certificate ...
