Abstract
The invention provides a highly-reliable face collation apparatus and biometrics data collation apparatus in both of which when a person is to be identified, even at the time of a collation in which characteristic data on the person approximates to characteristic data on one of the other persons, the characteristic data are comprehensively collated by combination, whereby the person and the other person can be clearly discriminated from each other to reduce collation errors. The face collation apparatus includes a face image acquiring unit for acquiring face images, a storage unit in which a plurality of different face images on each of persons who are collation targets are stored in advance in such a manner as to be associated with each of the persons, a calculating unit for calculating collation degree data obtained by comparing the acquired face images with the stored face images, an extracting unit for extracting face images of high collation degrees by a predetermined number from among the calculated collation degree data, and an identifying unit for identifying a person when all face images of the person are contained in results extracted by the extracting unit.
