Abstract

The invention belongs to the technical field of intelligent authentication, and discloses an identity authentication system and authentication method based on blockchain, a medium and a terminal. A data acquisition module acquires personal information of a user, sends the acquired related information and a corresponding data query verification request to a citizen information database, and sends the verified information to the data processing module; a citizen information database verifies the information and the personal information of the citizens in the database and returns a verification result; a data processing module performs Hash processing on the data, generates a public and private key pair for the data of each user, and links the processed data; the blockchain stores data which is processed by the data processing module and comprises a hash block and an affiliated ciphertext block, and carries out the identity authentication of the user; a department application terminal verifies the citizen information on the chain, and returns an on-chain authentication result is returned. According to the invention, the burden of the user can be greatly reduced, the risk of privacy information leakage is reduced, and efficient identity authentication can be realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent authentication, and in particular relates to a blockchain-based identity authentication system, authentication method, medium, and terminal. Background technique [0002] At present: with the rapid development of big data and cloud computing, the privacy protection of personal information is becoming more and more important. Incidents of illegal acquisition of personal information and data leakage occur frequently. Information security is no longer a personal issue, but a public management issues. In many occasions, we need to prove our identity, how to prove our identity without revealing personal privacy data, this requires a natural tamper-proof trusted data structure such as blockchain, combined with hash algorithm and public-private The key encryption mechanism can also ensure that the user's private information is not leaked. [0003] Identity authentication: Identity authentication is...
