Abstract

A system and method match a search print with one or more file prints stored in a database, wherein each of said prints including minutiae. The system and method receive a minutiae match report which includes a list of file prints which are possible matches with the search print. The minutiae match report is based on at least a comparison of coordinate locations and angles of rotation of the minutiae in the file prints with the minutiae in the search prints. The system and method determine an offset between a first singularity in the search print and a corresponding first singularity in the file print. Additionally, the system and method determines a first angle between at least one singularity in the search print and at least one minutia of the search print. A second angle between a corresponding at least one singularity in the file print and a corresponding at least one minutia of the file print is determined. The first angle and the second angle are compared and a first match indicator is generated based on the offset and the comparison of the first angle and the second angle.
