A fingerprint verification method includes: extracting ND sample feature points (ND is an integer greater than or equal to four) from a fingerprint image that has been sampled; assigning a sample numerical values to each of the sample feature points as sample numerical value information, the sample numerical values being obtained from a plurality of sample connection lines, which connect each of the sample feature points with LD close sample feature points (2 ≤ LD ≤ ND - 1, LD is an integer) 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 NR registration feature points (NR is an integer greater than or equal to four), associating m sample feature points (3 ≤ m ≤ ND and 3 ≤ m ≤ NR, m is an integer) among the ND sample feature points with m registration feature points among the NR registration feature points; and comparing a position relationship among the m sample feature points with a position relationship among the m registration feature points. <IMAGE>
