Abstract
A method for processing fingerprint information includes dividing an input image that corresponds to at least a portion of a user fingerprint into a plurality of first regions; dividing a registered image that had previously been stored into a plurality of second regions; selecting a first matching region from among the plurality of first regions, and selecting a second matching region from among the plurality of second regions, by comparing the plurality of first regions with the plurality of second regions; and matching the registered image with the input image by comparing the first matching region with the second matching region.
