Abstract

The present invention provides techniques for efficient searching of a multi-modal biometric database. Nested searching improves search efficiency by using the results of a previous biometric modality search to limit the search population for subsequent biometric searches. The method can also be used in combinations of non-biometric searches limiting subsequent biometric searches or vice versa.
