ABSTRACT:
A computer program product comprising a computer readable medium carrying program instructions for verifying a fingerprint when executed using a computing system, the executed program instructions executing a method, the method: producing a test image of a fingerprint-under-test; producing a test ridge map from the test image and a reference ridge map from each of one or more reference fingerprint images; extracting fingerprint points of interest from the ridge maps; screening candidate reference ridge maps based upon a correspondence between the points of interest from the reference ridge maps and the points of interest from the test ridge map wherein the correspondence includes a first threshold and one or more candidate ridge maps having the correspondence within the first threshold are included in a set of candidate ridge maps; comparing local ridge data surrounding one or more points of interest of the test ridge map within a second threshold with local ridge data surrounding corresponding one or more points of interest of each of the test ridge maps in the set of candidate ridge maps; and asserting a comparison signal responsive to a correspondence between the local ridge data of the test ridge map and the local ridge data from one or more candidate ridge maps of the set of candidate ridge maps.
