Patent ID: 7248722

Claim:
A fingerprint identification apparatus comprising: collation means for collating positions in prerecorded fingerprint templates with positions in collation fingerprint information, wherein the collation fingerprint information is input for comparison with the templates; calculating means for calculating the degree of matching between data in the templates and data in the collation fingerprint information; extraction means for extracting collation positions based on the calculated degree of matching at each position within the collation fingerprint information, the collation positions indicating the position of the prerecorded fingerprint templates relative to the collation fingerprint information; address distance calculating means for calculating address differences between the prerecorded fingerprint templates and a reference template; generation means for generating corrected coordinates by adding the address differences to the collation positions; and determination means for determining whether or not identity is established between one or more of the prerecorded fingerprint templates and the collation fingerprint information by calculating the number of prerecorded fingerprint templates for which the corrected coordinates differ by less than an allowable positional shift.
