AI Technical Summary
Technical Problem
Traditional identity authentication systems rely on centralized databases, which make it difficult to quickly verify data integrity and make sensitive information easy to be stolen, resulting in a high risk of fraud and identity theft.
Method used
This decentralized identity authentication method combines Merkle trees and zero-knowledge proofs. It generates an initial Merkle proof and stores it on the blockchain, then uses zero-knowledge proofs for identity verification, thus avoiding the direct exposure of user information.
Benefits of technology
Improve data integrity and verifiability, reduce the risk of fraud and identity theft, enhance user privacy protection, and defend against new attack methods.

Abstract
The invention discloses a decentralized identity authentication method and related equipment in combination with a Merkel tree and zero-knowledge proof. The method comprises the following steps: generating an initial Merkel proof through an identity provider; zero-knowledge proof is generated through a zero-knowledge proof module; requesting to obtain an initial Merkel proof corresponding to a user from an identity provider through an authenticator; the authenticator performs first identity authentication on the user according to the initial Merkel proof, and if the first identity authentication of the user is successful, the authenticator performs second identity authentication on the user according to the zero-knowledge proof; and if the second identity authentication of the user is successful, generating an identity authentication success result, and returning the identity authentication success result to the user. According to the method, the integrity and verifiability of data can be improved, the risks of fraud and identity embezzlement are reduced, a novel attack mode is effectively resisted, higher-level data security characteristics are realized, user privacy protection is greatly enhanced, and the method can be widely applied to the technical field of network security.
