SYSTEM AND METHOD FOR RECOGNIZING AND IDENTIFYING SUBJECT UNDER A SERIES OF CHANGES CONTROLLED BY THE SUBJECT TO BIOMETRICS, AND RECORD MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a system and method for recognizing and identifying a subject under a series of changes controlled by the subject to biometrics and a record medium. SOLUTION: This invention defines new biometrics called as resultant biometrics. The resultant biometrics are a combination of the conventional biometrics and a change specifically controlled. In other words, signals of the resultant biometrics are arranged as a sequence of a short-interval biometrics signal and altered according to a specified pattern. A finger print or a palm print thus obtained is turned to a continuous pressing image, for example, by letting a subject apply a torque or a rotation or both thereof for an image gaining time length (a controlled change). A physical method of letting the subject deform the image makes an action apart of the resultant biometrics and the finger print of the palm print a physiological part of the resultant biometrics.
