Identity authentication method, system and device based on block chain and computer equipment

Abstract

The invention relates to an identity authentication method, system and device based on a block chain, computer equipment and a storage medium. The method comprises the following steps: receiving a login request sent by a user terminal, the login request carrying private key signature data; responding to the login request, obtaining public key data; obtaining equipment identification data of the user terminal when verification of the private key signature data is completed according to the public key data, and generating key data according to the equipment identification data, and sending the key data to the user terminal, receiving authentication data submitted by the user terminal for the key data, and when the authentication data submitted by the user terminal passes the verification, determining that the identity authentication is passed. According to the scheme, decentration is carried out in a blockchain mode, so that authentication failure caused by downtime of the central node is avoided; by introducing a double-authentication mechanism of equipment authentication and key data based on equipment identification data and private key authentication, behaviors such as signaturedenial can be avoided, the identity authentication accuracy is improved, and the data security is guaranteed.

Description

technical field [0001] The present application relates to the technical field of blockchain data, in particular to a blockchain-based identity authentication method, system, device, computer equipment and storage medium. Background technique [0002] With the popularity of the mobile Internet, more and more users cannot do without the Internet in their daily activities. The basis of activities on the Internet is digital identity, which is the user's identity in the virtual life of the network and can correspond to the ID card in real life. In the blockchain, it is particularly important to authenticate the user's identity and ensure the authenticity and reliability of the user's identity. Only by ensuring the user's identity can a series of subsequent transactions and activities generated by the user take effect, and data integrity and privacy can be guaranteed. [0003] However, in existing identity authentication schemes, centralized identity authentication relies on the ...

AI Technical Summary

Problems solved by technology

[0003] However, in existing identity authentication schemes, centralized identity authentication relies on the stability of a single system. Once downtime or data leakage occurs in the centralized organization, it is easy to cause information security incidents, and the existing authentication usually uses SMS verification codes. Or based on event authentication (handwriting or face recognition) and other methods

[0004] In the above authentication methods, SMS verification codes are easy to be intercepted or forged, and the accuracy of event-based authentication cannot be effectively guaranteed. Therefore, the existing identity authentication schemes have problems in which the authentication accuracy cannot be fully guaranteed, which may easily lead to user information security and even economic loss. security threats
