Abstract
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.
