Patent ID: 7835548

Claim:
A method of conducting biometric identification matching comprising: dividing an entire population into subpopulations; generating a matrix including a plurality of matrix entries; associating each of the matrix entries with one of the subpopulations and with one of a plurality of matching systems that corresponds to the one subpopulation; obtaining biometric data, including the obtained biometric data in a probe, and determining a row in the matrix corresponding to characteristics of the probe; conducting a 1:N identity match between the probe and each subpopulation using the one matching system corresponding to each subpopulation; determining a candidate match when the probe matches a matching system enrollment data record in the corresponding one matching system; conducting a 1:1 verification to eliminate the candidate match if the candidate match is not a true match, the corresponding one matching system being associated with a reliable one of a plurality of biometric modalities; storing the candidate match in a queue when the candidate match is confirmed; and communicating the queue to an entity requiring the identity match.
