A method including attempting a match of a series of sample biometric signatures into a database having one or more valid biometric signatures; accumulating a first number N 1 of consecutive failed match attempts prior to a successful match wherein a failed match attempt occurs when one of the sample biometric signatures does not match any of the valid biometric signatures; comparing the first number N 1 and the second number N 2 to a predetermined threshold value M for a match comparison; validating a successful match when the comparing feat determines the first number N 1 and the second number N 2 both have a particular relationship to the predetermined threshold value M; and recording a second number N 2 equal to the value of the first number N 1 when a sample biometric signature matches one of the valid biometric signatures.
