A fingerprint verification method includes extracting N<SUB>D </SUB>sample feature points from a fingerprint image that has been sampled, assigning sample numerical values to each of the sample feature points as sample numerical value information. The sample numerical values are obtained from a plurality of sample connection lines, which connect each of the sample feature points with L<SUB>D </SUB>close sample feature points, which are close to each of the sample feature points. Based on results of comparison between the sample numerical value information and registration numerical value information, which is registration numerical values assigned to each of N<SUB>R </SUB>registration feature points, associating m sample feature points among the N<SUB>D </SUB>sample feature points with m registration feature points among the N<SUB>R </SUB>registration feature points. A position relationship among the m sample feature points is compared with a position relationship among the m registration feature points.
