Identity authentication method based on secret graphic code sharing mechanism

Abstract

The invention relates to an identity authentication method based on a secret graphic code sharing mechanism. The identity authentication method comprises the following steps: extracting first biological characteristic information of a first authenticated person; converting the first biological characteristic information into a first graphic code having a symbol logic form; mapping the first graphic code into n shadow secrets, and respectively storing the shadow secrets in different places; extracting second biological characteristic information of a second authenticated person; converting the second biological characteristic information into a second graphic code having a symbol logic form; selecting t shadow secrets from the n shadow secrets so as to reconstruct a graphic code; judging whether the second graphic code accords with the reconstructed graphic code or not; if so, determining that the first authenticated person and the second authenticated person are the same person; or else, determining that the first authenticated person and the second authenticated person are two different persons. According to the invention, the problem that real-name identity information is tampered, forged and stolen can be effectively prevented.

Description

technical field [0001] The invention relates to the field of identity authentication, in particular to an identity authentication method based on a graphic code secret sharing mechanism. Background technique [0002] Identity real-name authentication is the process of judging the identity of individuals who want to visit by using a proprietary authentication system with registered user information. Real-name authentication provides authentication of the real identity of system visitors, and is mainly used to prevent unauthorized users from accessing system resources. Generally, electronic technology, biotechnology, or a combination of electronic technology and biotechnology is used to authenticate the authenticity of the identity of the authorized user. Divided from the relationship between the credentials used for authentication and the user, identity authentication can be divided into three categories: user-known authentication, user-held token authentication, and user bi...

AI Technical Summary

Problems solved by technology

[0012] To sum up, compared with the ever-changing progress of information technology and the Internet, the existing identity real-name authentication technology is obviously lagging behind and has large loopholes, leading to rampant activities of identity tampering, forgery and illegal use of other people's identity documents, which is threatening the credit of modern society System and Integrity Security
