Abstract:
1. A fingerprint verification method using a fingerprint image, the method comprising: extracting N assigning 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 L comparing each of the sample numerical values assigned to each of the sample feature points with each of registration numerical values assigned to each of N deleting a sample feature point among the N associating one registration feature point among the assigned registration feature points with only a sample feature point among the remaining sample feature points excluding the deleted sample feature point, the sample feature point including sample numerical values that have been assigned in common at a second percentage or more to the one register feature point; and when the number of sample feature points associated with the registration feature points is m or more (m is an integer defined as 3≦m≦N
