10. The method of claim 9 , further comprising: performing the matching operation between all the templates in the biometric corpus and all prototype templates in each of the typicality proto-groups to generate template-match scores, and averages the template-match scores to generate template-typicality scores for each of the typicality proto-groups; dividing the biometric corpus into a set of proto-corpuses for each of the typicality proto-groups based on the template-typicality scores of each of the typicality proto-groups.

The method of claim 10 , further comprising: dividing the template-typicality scores of each of the typicality proto-groups into Q number of template-typicality ranges, each of the template-typicality ranges corresponding to one proto-corpus of the set of proto-corpuses, each of templates in the one proto-corpus having a template-typicality score within a template-typicality range corresponding to the one proto-corpus, each proto-corpus of the set of the proto-corpuses having about a same number of templates as other ones of the set of proto-corpuses.
