Identity authentication method of identity card and holder based on multi-biological characteristics

Abstract

The invention provides an identity authentication method of an identity card and a holder based on multi-biological characteristics. The invention mainly assists in solving potential safety hazard problems existing in a cross-application process in the prior art. An embodiment comprises the steps that: when identity card registration transaction is carried out, characteristics of fingerprints, iris information and face image of a citizen are acquired; a uniform matrix image AI, a domain element matrix image UI and an offset matrix image SI are acquired and saved respectively in a population information database and an identity card chip; when authentication is carried out, an authentication terminal acquires characteristics of the fingerprints, the iris information and the face image of an identity card holder; the uniform matrix image AI and the domain element matrix image UI are searched for in the population information database based on personal basic information PI; and identity authentication of the identity card and the holder is carried out by using three biological characteristics of the fingerprints, the iris information and the face image, the uniform matrix image AI, the domain element matrix image UI and the offset matrix image SI. According to the invention, an authentication accuracy rate and overall authentication system safety are improved and potential safety hazard existing in the cross-application process is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of information security and relates to a physical identity authentication method for an ID card with multiple biological features, which can be used to quickly and accurately identify the identity of an ID card holder and an ID card, and effectively protect the privacy and security of biological features. Background technique [0002] In order to quickly and accurately identify the identity of the ID card holder and the ID card through machine reading, maintain national security and social stability, and effectively prevent illegal and criminal acts such as fraudulently using other people's ID cards and forging and changing ID cards. The 23rd meeting of the Standing Committee of the National People's Congress reviewed and passed the Amendment to the Resident Identity Card Law of the People's Republic of China (Draft). The draft further requires citizens to register their fingerprint information when they app...

Problems solved by technology

[0006] Second, the issue of biometric privacy protection is not considered

Once the biometrics are stolen, the original biometric information can be restored or the rights and interests of corresponding legitimate users in other biometric application systems can be obtained through related attacks, resulting in the leakage of user privacy information and related major economic losses, seriously endangering national security. and social stability

[0007] Finally, since the fingerprint and face information used are stored separately in the ID card, it is necessary to separately protect the fingerprint and face information to ensure the privacy of these biometric information, which increases the cost of biometric privacy protection. At the same time, higher requirements are put forward for the security of the entire authentication system, because the leakage of any information in fingerprint and face information will lead to a decrease in the security of the entire system
