Identity authentication method and device based on blockchain, storage medium and equipment

Abstract

The invention relates to an identity authentication method and device based on a block chain, a computer readable storage medium and computer equipment. The method comprises the following steps: receiving a service request of a user, obtaining authorization information of the user according to the service request, searching a target block corresponding to the authorization information from a blockchain, and obtaining registration data of a user corresponding to the authorization information from the target block, calling an intelligent contract corresponding to the service request when the authorization verification is passed, executing the declared identity authentication logic by the intelligent contract, obtaining an identity authentication result based on the registration data, and feeding back the identity authentication result. For the service provider, the identity information of the user cannot be directly contacted, and the identity authentication result fed back by the blockchain can be obtained or used only on the premise of user authorization, so that for the user, the user can be prevented from directly providing the identity information of the user for a merchant, and the problem of leakage of personal information of the user is avoided from the source.

Description

technical field [0001] The present application relates to the technical field of block chain, in particular to a block chain-based identity authentication method, device, computer-readable storage medium and computer equipment. Background technique [0002] With the development of the Internet, there are more and more scenarios that require identity authentication. Identity authentication means that when the user handles related business or provides other services for the service provider, the service provider will provide the user with the identity information provided by the user. The process of authenticating to determine whether the user is a legal citizen or has permission to use certain resources. [0003] In traditional schemes, the "real name + real certificate" method is generally used for identity verification, but this verification method leads to the arbitrary authorization and use of personal information such as ID card and mobile phone number, and the leakage o...
