Abstract

The embodiment of the invention discloses a multi-biological-characteristic fusion identity authentication method, which adopts more than two types of biological characteristic identity information to carry out identity authentication and attestation so as to bring higher identification accuracy. The method of the embodiment of the invention comprises the following steps: collecting at least two types of biological characteristic identity information of a user to be identified; carrying out characteristic extraction on the at least two types of collected biological characteristic identity information to obtain corresponding characteristic information; according to the characteristic information, establishing characteristic matrixes, wherein the biological characteristic identity information, the characteristic information and the characteristic matrixes have one-to-one correspondence relationships; carrying out normalization processing on all characteristic matrixes; carrying out dynamic weighting fusion on all normalized characteristic matrixes to obtain a fusion characteristic matrix; according to the fusion characteristic matrix and a preset corresponding standard matrix , carrying out matching to obtain a corresponding matching score; and according to a Bayesian decision model and the matching score, obtaining an identity identification result of the user to be identified. The embodiment of the invention also provides a multi-biological-characteristic fusion identity authentication device.

Description

technical field [0001] The present invention relates to the field of financial self-service equipment, in particular to a multi-biometric feature fusion identity authentication method and device. Background technique [0002] Multi-biological feature fusion identification technology refers to the identification of personal identity by using the fusion of multiple physiological features inherent in people. Compared with traditional identity authentication methods, the biggest feature of biometric authentication is to identify the user's own characteristics. These biometrics are unique and not easy to be impersonated or stolen; in addition, the biometrics can be "carried with you" and used at any time without regular maintenance. Therefore, the personal identification system based on biometric identification technology has higher security, reliability and effectiveness, and is receiving more and more attention from people, and has begun to enter the financial field.
