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.

Abstract: Measurement of a physical property such as coercive force of a member to be inspected is performed at a plurality of locations in one region of the member. Similar measurement is performed in a plurality of different regions of the member and a maximum or minimum value (extreme value) is determined for each of the regions. On the basis of the extreme values thus determined, a recurrence period is determined in accordance with an extreme value statistic theory with the aid of a computer, whereon an estimated maximum value of the physical property of the member as a whole is determined from the recurrence period. On the basis of the estimated maximum value, the degree of deterioration of the member is predicted by the computer by consulting the data indicating the previously determined relation between the physical property and the degree of deterioration.
