Abstract: There are provided a living body collating device, a living body collating system and a living body collating method, which is equipped with optimization candidate data extracting means 35 for extracting optimization candidate data for data renewal from past record data of living body information achieved, optimization candidate data storage means 36 for storing the optimization candidate data extracted by the optimization candidate data extracting means 35, and renewal storage means 37 for storing, as new registration data, the data having higher priorities of the optimization candidate data stored in the optimization candidate data storage means 36 and registration data stored in registration data storage means.

Abstract: The present invention relates to an image comparison apparatus and method in which images are acquired using a photograph unit and comparing them with a registration of memorized images. The photograph unit acquires a plurality of images of the photograph object during a period from detection of the photograph object by the object detection sensor until a press of a button. After which, the acquired image is compared with previously memorized registration images and a comparison result indicating whether or not a match exists is outputted.

Abstract: The purpose of the invention is to provide an apparatus, system and method for personal identification with an improved capability of generating registration data in which biometrics information of a person to be identified can be acquired and accumulated each time identification is used at an operation such as unlocking of a door only by registering ID information and so on with no biometrics information of the person to be identified registered in advance and in which registered data of the person can be efficiently generated based on the log data thus accumulated.
