A fingerprint verification process system comprises analysis means for analyzing fingerprint data to determine a verification scheme for verifying fingerprint, and execution means for verifying fingerprint using the determined verification scheme. The analysis means (i) transforms a coordinate position of each searched fingerprint feature point included in the fingerprint data being searched to a coordinate position in a coordinate system based on a coordinate reference point included in the filed fingerprint data, (ii) with respect to a group of searched fingerprint feature points located around the coordinate reference point and a group of filed fingerprint feature points included in the filed fingerprint data, carries out (a) a check of the presence or absence of any singular point sprinkled in a vicinity coordinate range of the coordinate reference point which is specified in a fingerprint verification parameter, (b) a zone check of a coordinate reference point vicinity coordinate range, and (c) a quality check of a group of feature points located within a coordinate reference point vicinity coordinate range, (iii) determines which of an axis verification scheme or an alignment verification scheme is to be used.
