Abstract
A method and apparatus for expandable biometric searching are provided. The method preferably includes forming a plurality of biometric records. Each of the biometric records includes at least one biometric index and biometric data associated with the at least one biometric index. The method also includes assigning each of the plurality of biometric records to a plurality of biometric data groups so that each of the plurality of biometric data groups includes a full range of biometric indexes and about the same number of biometric records. Each of the plurality of biometric data groups is preferably uncorrelated to the biometric indexes. The method further preferably includes assigning each of the plurality of biometric data groups to a plurality of biometric searching engines so that each of the plurality of biometric data groups is assigned to only one of the plurality of biometric searching engines. An apparatus for expandable biometric searching preferably includes a plurality of biometric data groups each of which includes a plurality of biometric records having at least one biometric index and biometric data and a full range of biometric indexes. Each of the plurality of biom…
