Method and device for confirming safety level of biology identification systemic

Abstract

The invention embodiment discloses a method for identifying the security grade of a biometric security certificate system, including the procedures as follows: a. setting the corresponding relationship between related parameters and the security grade of the biometric security certificate system in advance, the related parameters comprise the security measurement adopted by the biometric security certificate system and the FMR or the FNMR of biometric certificate calculation adopted by the biometric security certificate system; b. identifying the security measurement adopted by the biometric security certificate system and the FMR or the FNMR of biometric certificate calculation adopted by the biometric security certificate system; c. according to the corresponding relationship preset in procedure a, gaining the corresponding security grades of the security measurement and the FMR or FNMR identified in procedure b, the security grade is regarded as the security grade of the biometric certificate system. The invention embodiment can calibrate the security grade of the biometric certificate system. The invention embodiment also discloses a device for identifying the security grade of the biometric certificate system.

Description

technical field [0001] The invention relates to the field of biometric authentication in information security technology, in particular to a method and device for determining the security level of a biometric authentication system. Background technique [0002] In the current information society, information security is the focus of everyone's attention. Identity authentication is the process of verifying the user's identity. It is the first and most important link in information security. Biometric authentication system is also a type of identity authentication system, which uses measurable physiological or behavioral characteristics of the human body to verify identity, which is essentially a pattern recognition system. The biometric authentication system obtains biometric data from people, extracts features from it, and compares them with the feature templates pre-existed in the database. Therefore, it has the characteristics of high recognition accuracy, easy portabilit...

Problems solved by technology

However, in the field of biometric authentication, for different biometric authentication systems, it is impossible to determine the ability of the system to resist spoofing attacks, and it is impossible to provide users with a reference standard to distinguish the security indicators of different biometric authentication systems.

There is a lack of objective evaluation criteria for biometric authentication systems, and it is impossible to adopt biometric authentication systems with appropriate security levels for different occasions
