Abstract:
1. A method for use in print matching apparatus comprising the steps of: enrolling a print of a user; extracting a set of matching features from the enrolled print; comparing the extracted features of the enrolled print to extracted features of each print in a set of reference prints, wherein each reference print in the set is from a person other than the user, and determining a highest non-matching score; determining at least two minimum and maximum matched score threshold pairs based on characteristics of the print matching apparatus; and storing the matching features of the enrolled print, the highest non-matching score, and the at least two maximum and minimum matched score threshold pairs for use in verifying a subsequently captured print of the user, wherein the highest non-matching score and a selected one of the minimum and maximum matched score threshold pairs are used in determining a verification threshold used in verifying the subsequently captured print of the user.
