1. 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;
