Method and system for conducting identity matching

A method of managing large scale biometric data identity matching when subsets of an overall population have different combinations of biometric data, said method comprising:

• identifying a plurality of biometric modalities to be used in conducting identity matches;
• determining data quality levels for each of the biometric modalities;
• defining a plurality of subpopulations;
• generating a matrix including a grid, defining a plurality of matrix entries with the grid, positioning designations for each of the subpopulations along a first side of the matrix and along a second side of the matrix;
• determining one of the plurality of biometric modalities to be a primary biometric modality and determining at least one matching algorithm;
• determining whether the at least one matching algorithm is compatible with each matrix entry, and when the at least one matching algorithm is compatible with the matrix entry
• assigning a corresponding one of a plurality of matching systems configured to execute the at least one matching algorithm to the matrix entry;
• assigning additional ones of the plurality of matching systems to the matrix entry, wherein the additional matching systems are configured to conduct 1:1 or 1:few matching after the corresponding one of the matching systems conducts a 1:N identity matching;
• obtaining biometric data, configuring the obtained biometric data as a probe, and determining characteristics of the probe such that a row in the matrix, to be used to define matching for an entire population, is determined;
• determining a first matrix entry corresponding to the characteristics of the probe and to a first one of the subpopulations, and determining at least one matching system corresponding to the first subpopulation;
• comparing the probe against enrollment data records stored in the corresponding at least one matching system to conduct the identity match;
• storing information regarding a matching enrollment data record in a queue when the probe matches an enrollment data record;
• and
• communicating the queue to an entity performing the identity match.
