Fingerprint collation device, fingerprint collation method and fingerprint verification program

摘要

A plurality of partial images of a fingerprint input from a fingerprint input device (7) are reconstructed by correcting a portion overlapping the partial image in the reconstruction processing unit (106), and the feature is extracted in the fingerprint feature extraction unit (110) and stored in the input feature amount memory. The comparison of the characteristic values stored in the input feature amount memory in the collation processing part and the characteristic value stored in the registered feature memory is compared with the preset threshold value obtained by performing the DP comparison (dynamic programming), and the distance value is smaller than the threshold value If the distance value is greater than the threshold value, it is judged that the result is disagreement.
