Biological feature information management method and system

Abstract

The invention relates to a biological feature information management method and system. The method comprises the steps of obtaining a fingerprint image which is input by a user and is used for carrying out identity authentication; identifying whether the user is a legal user or not according to the fingerprint image and a preset fingerprint template; if the user is the legal user, collecting a finger image of the user according to a preset sampling frequency; judging whether the finger image is the finger image of a living body or not according to a preset living body detection rule; and determining whether the identity authentication is successful or not according to a living body identification result. According to the embodiment of the method and the system, through collection of the fingerprint image, whether the user is the legal user or not is identified, through collection of the finger image of the user, whether a finger of the user carrying out press operation is a living body finger or not is determined, so the problem that an illegal user disguises as the legal user through utilization of disguise technologies such as fingerprint membrane and steals the biological feature information of the user is solved, and the security and confidentiality of the biological feature information management system are improved.

Description

technical field [0001] The invention belongs to the field of information management, and in particular relates to a biometric information management method and system thereof. Background technique [0002] With the development of information identification algorithms and the popularization of mobile payment, the identification and management of biometric information has attracted more and more attention from the public. Biometric information is not only an important indicator of the user's life and health, but also the user's "identity certificate", which is widely used in the field of financial transactions. However, the existing biometric management system mainly distinguishes the user's identity or analyzes the user's biometric information by collecting fingerprint information. However, by collecting fingerprint information, it is impossible to identify whether the user uses fake fingerprints, for example, through the fingerprint film, to impersonate the identity, result...
