Registration method for biometrics authentication system, biometrics authentication system, and program for same

Abstract

The present invention provides a registering method of a biological measure certification system, the biological measure certification system and a procedure thereof. The biological measure certification system certificates an individual by biological measure information. A processing unit obtains the biological measure information of one living body for a plurality of times by a detection unit to judge mutual similarity among biological measure characteristic data groups picked up from the biological measure information obtained for a plurality of times and register a plurality of biological measure characteristic data groups with high similarity in a memorizing unit. Therefore, the present invention can implement validation fit for the change of the living body state.

Description

technical field [0001] The present invention relates to a registration method of a biometric authentication system, a biometric authentication system and a program thereof, which authenticate individuals using biometric features that are part of a human body, and more particularly to a registration method of a biometric authentication system, a biometric authentication system and its procedures to authenticate individuals by verifying detected biometric information with registered biometric information. Background technique [0002] There are a large number of human body characteristics that can identify individuals in the human body, including fingerprints, palm prints, palm shapes, iris patterns, retinal features, blood vessel patterns, facial features, voiceprints, gait, outer ears, DNA, etc. With the development of biometric technology in recent years, various devices for identifying such biometric features as part of the human body to authenticate individuals have been ...

Problems solved by technology

[0006] However, in the conventional method of extracting and registering mutual data, although the noise of the biometric detection device and the difference in the detection state at the time of biometric detection can be excluded, registering the mutual data means that it is different from the actually obtained personal biometric data set. It is completely consistent, and there is a situation where the amount of feature data is different from the amount of feature detection data

Therefore, at the time of authentication, accurate verification may not be obtained when verifying the verification data with registered data

[0007] In addition, because it is a measurement performed on a living body, it is necessary to consider changes due to physical conditions, and in the case where mutual data has been registered, if the physical condition changes during the authentication period compared with the registration, even if the person is in fact the same person, it would also be difficult to authenticate the person, which would cause all sorts of problems
