Problems solved by technology

However, the general blockchain authentication technology currently on the market has a single verification method. For example, when only the user's fingerprint is used for verification, if the user's palm is bandaged due to injury, the verification will be inconvenient, which will affect the transaction efficiency.

Abstract

The invention discloses an identity authentication system and method based on a block chain technology. The identity authentication system comprises a client terminal, a cloud server and a third-partyplatform, wherein a user sends a registration request to the cloud server through the client terminal, the cloud server allocates a unique identification code to the user, the cloud server performs encryption according to the identification code and the biological characteristics of the user to generate a secret key, and when the user performs transaction on the third-party platform, the cloud server decomposes the public key and the private key of the user into a plurality of sections respectively by acquiring the public key of the user and the private key input by the user, verifies the sections respectively, allows the user to perform transaction if the number of verification passing times is greater than a set threshold, otherwise, does not allow the user to perform transaction and gives an alarm. According to the invention, identity authentication is performed through consideration in multiple aspects, and the characteristic of non-tampering of the application block chain technology is adopted to solve the problem of single identity authentication mode in the prior art, so that the transaction security is ensured, and the variable flexibility of the authentication mode is improved.

Description

technical field [0001] The invention belongs to the technical field of identity authentication, and in particular relates to an authentication system and method of an identity authentication system based on block chain technology. Background technique [0002] As the latest term in the field of information technology, blockchain technology has the advantages of "unforgeable", "traceable", "open and transparent", etc. Based on these characteristics, blockchain technology is widely used. Among them, the application of blockchain technology to identity verification has a good prospect. However, the general blockchain authentication technology currently on the market has a single verification method. For example, when only the user's fingerprint is used for verification, if the user's palm is bandaged due to injury, the verification will be inconvenient, which will affect the transaction efficiency.
