ABSTRACT:
To provide an apparatus for pre-selecting fingerprint cards having certain similarity to an S-card to be identified, at a high-speed, among a plurality of F-cards, an apparatus of the invention comprises: an F-side cluster index determination section (2) for designating a cluster wherein feature data of the plurality of F-cards are to be classified according to features extracted from the plurality of F-cards; an F-card feature storing section (3) for storing the feature data of the plurality of F-cards in the cluster designated by the F-side cluster index determination section (2); an S-card feature storing section (5) for temporarily storing feature data of the S-card; an S-side cluster index determination section (6) for designating clusters to be retrieved according to a combination of features extracted from the S-card; and a fingerprint card matching discrimination unit (8) for pre-selecting the fingerprint cards by comparing the feature data of the S-card with the feature data of the plurality of F-cards stored the clusters designated by the S-side cluster determination section (6).
