摘要：An input unit receives the input a fingerprint image of a user. A classification unit classifies the fingerprint image inputted by the input unit into any of a plurality of groups
defined on the basis of individual differences of the fingerprint. Based on the classification result of fingerprint width, namely, the type of a group determined by the classification unit, a switching control unit selects either a normal fingerprint width feature extraction processing unit or a narrow fingerprint width feature extraction processing unit provided in a feature extraction unit. A feature extraction unit processes the fingerprint image, using processing methods defined respectively for the plurality of groups. A verification data preparation unit prepares fingerprint verification data. A fingerprint identification unit checks the fingerprint verification data prepared by an identification data preparation unit against fingerprint identification data enrolled in a biological information storage unit.
