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 blockchain technology, comprising a client terminal, a cloud server and a third-party platform; a user sends a registration request to the cloud server through the client terminal, and the cloud server assigns a unique identification code to the user; The cloud server encrypts and generates a key according to the user's identification code and biometric characteristics; when the user conducts a transaction on a third-party platform, the cloud server obtains the user's public key and the private key input by the user, and separates the user's public key and private key respectively. It is decomposed into several sections and verified separately. If the number of verification passes is greater than the set threshold, the user is allowed to trade, otherwise the user is not allowed to trade and an alarm is issued. The present invention performs identity authentication through various considerations, and uses the non-tamperable feature of blockchain technology to solve the problem of a single identity verification method in the prior art, which not only ensures the security of transactions, but also improves the reliability of the verification method. Become flexible.

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 a new term in the field of information technology, blockchain technology has the advantages of "unforgeable", "traceable", "open and transparent", etc. Based on these characteristics, the application of blockchain technology is very extensive. Among them, the application of blockchain technology to identity verification has good prospects. However, at present, the general blockchain authentication technology in 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, thereby affecting the transaction efficiency.
