1. A method of normalizing biometric scores, which comprises: enrolling in a biometric database a plurality of individuals by storing in said database for each individual a plurality of biometric templates of one type; comparing each biometric template in said database with every other biometric template of said database to obtain biometric scores, wherein the plurality of biometric templates of the one type are compared using different biometric applications, wherein scores produced by the different biometric applications are in different ranges; normalizing the biometric scores in the different ranges to be in a common range; if a normalized biometric score is obtained by comparing one biometric template of an individual with an other biometric template for that same individual, putting that normalized biometric score in a matching category; and analyzing the normalized scores in the matching category to determine a probability that a particular score is a matching score.
