Abstract: A system includes an interface receiving a search print record including a first direction image of a search print and a file print record including a second direction image of a file print, and a processing device. The processing device performs a method and a computer-readable storage medium stores code for programming a computer to perform the method, which includes: aligning the first and second direction images to identify an overlapping and a non-overlapping area; comparing block direction between the first and second direction images within the overlapping area; performing a rationality analysis on the aligned direction images to at least determine whether one of the direction images and the non-overlapping area of the other direction image are from a different finger; and generating a similarity score based on the block direction comparison and the rationality analysis, which indicates a measure of similarity between the search and file prints.

Abstract: A print identification system performs the following: comparing a primary search print to each of a plurality of file print to generate a primary sorted match report having a first set of file IDs each associated with a first match score; applying a decision logic to the first match scores to determine a status of the corresponding file prints a strong match, a possible match or no match to the search print; for each file print identified as a strong match, compare that file print against file prints identified as a possible match or no match to generate a sub-match report including at least a portion of the first set of file IDs each associated with a second match score; and modifying the primary sorted match report based on at least one of the second match scores to generate a final sorted match report.
