A biometrics authentication device which detects body characteristics, performs verification against registered biometrics data, and performs individual authentication, by which confidentiality is improved even when biometrics data is separated, distributed and stored. A biometrics information key is created from biometrics data detected by a detection device, the biometrics data is divided into a plurality of portions, and the portions are stored on different media. The biometrics information key is stored on one media, and at the time of authentication, the separated biometrics data portions are combined and a biometrics information key is created and is compared with the biometrics information key, to judge the linked relationship. Hence confidentiality of the association of the individual separated data portions can be improved even when the biometrics data is separated, distributed and stored, contributing to prevent illicit use resulting from leakage or theft of biometrics data.

Biometrics authentication method, media for individual authentication, and biometrics authentication device

According to the present invention, first, the first biometric information 'a' is divided equally and biometric information 'a' and biometric information &#x201c;a'&#x201d; are generated, the second biometric information &#x201c;b&#x201d; is divided equally and biometric information &#x201c;b&#x2032;&#x201d; and biometric information &#x201c;b&#x2033;&#x201d; are similarly generated. Then the biometric information &#x201c;a&#x2032;&#x201d; that is the first half of the first biometric information &#x201c;a&#x201d; and the biometric information &#x201c;b&#x2032;&#x201d; that is the first half of the second biometric information &#x201c;b&#x201d; are combined to generate one piece of biometric informationfor a person. The biometric information &#x201c;a&#x2033;&#x201d; that is the second half of the first biometric information &#x201c;a&#x201d;, and the biometric information &#x201c;b&#x2033;&#x201d; that is the second half of the second biometric information &#x201c;b&#x201d;, are similarly combined to generate the other piece of biometric informationfor the person. The biometric informationandare stored and used for matching later.

Personal authentication apparatus and personal authentication method

A biometrics authentication system detect body characteristics, verify the characteristics against registered biometrics data to perform individual authentication. In 1:n authentication, a plurality of different type biometrics database sets of a user are registered in a database, and at the time of verification of one type biometrics data set with one type registered biometrics data set, the control unit judges whether similar biometrics data sets of other person are registered, and if other person's similar biometrics data sets are registered, performs verification of each of the another type biometrics data sets of the plurality of similar biometrics data sets with the detected another type biometrics data set, and identifies the individual in question.
