AbstractA biometric system that uses readings from a plurality of biometrics of a user is disclosed. The biometric system includes a first and second biometric readers, a first and second biometric matching engines and a processor. The first biometric reader producing a first measured biometric that is processed by the first biometric matching engine to deliver a first value, which is indicative of a likelihood that the first measured biometric matches a first stored biometric reading. A plurality of first values are gathered prior to the first value. The second biometric reader delivers a second measured biometric for processing by the second biometric matching engine to produce a second value, which is indicative of a likelihood that the second measured biometric matches a second stored biometric reading. A plurality of second values are gathered prior to the second value. The first and second biometric readers measure a different biometric, or the first and second biometric matching engines use a different algorithm. The processor normalizes the first value according to the plurality of first values, normalizes the second value according to the plurality of second values, and determines if the user matches a person using the normalized first and second values.
