Abstract:
A method of expandbly storing and searching the biometric data, the method comprising the steps of:forming a plurality of biometric records, each of the plurality of biometric records including at least one biometric index and biometric data associated with the at least one biometric index;forming a multi-dimensional virtual space having the data structure with the plurality of biometric records stored therein and generally defined by a configuration of a tree, each nodal region at each level of the tree having a generally spherical shape;assigning each of the plurality of biometric records to one of a plurality of biometric data groups;assigning each of the plurality of biometric data groups to a plurality of biometric searching engines for performing a search of biometric data from the plurality of biometric data groups so that each of the plurality of biometric data groups is assigned only one of the plurality of biometric searching engines; andcontrolling the plurality of data groups so as to construct the multi-dimensional space and to construct internal maps for each data group being controlled.
