Abstract

The invention discloses a biological characteristic information and identity information association method, system and device, and the method comprises the steps: in an acquisition stage, collecting the biological characteristic information of a user at a biological characteristic information side, and generating a biological characteristic abstract value according to the biological characteristic information; storing the biological characteristic information and the generated biological characteristic abstract value through a biological characteristic library; encrypting the biometric abstract value and converting the biometric abstract value into a biometric encryption serial number of a user identity information side; and storing the user identity information and the biological characteristic encryption serial number. In the authentication stage, user identity information is extracted, and a biological characteristic encryption serial number corresponding to the user identity information is obtained; decrypting the biological characteristic encryption serial number to obtain a biological characteristic abstract value; and retrieving the biological characteristic information according to the biological characteristic abstract value for comparison and authentication. According to the technical scheme, the biological characteristic information and the identity information are isolated, the abstract information is protected through encryption, catastrophic influence caused by library file leakage is avoided, and safety is high.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of information processing, and in particular to a method, system and device for associating biometric information and identity information. Background technique

[0002] With the development of information technology, how to accurately identify a person's identity and protect information security has become a key technical problem that must be solved. Biometric identification uses the inherent physiological characteristics of the human body, such as fingerprints, face images, irises, etc., and behavioral characteristics such as handwriting, voice, gait, etc. to identify individuals. Biometric technology uses human biometrics for identity authentication. Human biometrics usually have the characteristics of being measurable or automatically identifiable and verified, hereditary or lifelong, so biometric authentication technology has greater advantages over traditional authentication t...
