Blockchain-based identity authentication system, authentication method, medium, and terminal

Abstract

The invention belongs to the technical field of intelligent authentication, and discloses a blockchain-based identity authentication system, an authentication method, a medium, a terminal, and a data collection module that collects user personal information, and sends the collected relevant information and corresponding data query verification requests to the citizen information database; at the same time, the verified information is sent to the data processing module; the citizen information database verifies the information and the citizen's personal information in the database, and returns the verification result; the data processing module performs Hash processing on the data, and The user's data generates a public-private key pair; at the same time, the processed data is uploaded to the chain; the block chain stores the data processed by the data processing module, including the hash block and the attached ciphertext block; at the same time, the user's identity authentication is performed; The citizen information on the chain is verified; at the same time, the verification result on the chain is returned. The present invention can not only greatly reduce the user's burden and reduce the risk of privacy information leakage, but also achieve efficient identity authentication.

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...

AI Technical Summary

Problems solved by technology

[0006] Through the above analysis, the problems and defects of the existing technology are: the existing identity verification method directly exposes the user's private data for identity authentication, does not associate the user's block number with the user data, and is inefficient
