Abstract:
1. A hybrid biometric authentication device, comprising: a plurality of feature extraction portions that respectively extract, from biometric information, a plurality of types of feature information that have mutually distinct properties; a feature combining portion that generates hybrid feature information by combining the plurality of types of feature information respectively extracted by the plurality of the feature extraction portions; a feature information storage portion that stores the hybrid feature information generated by the feature combining portion; a plurality of similarity computation portions that separate each of new information and registered information into the plurality of types of feature information before combined, and compute a plurality of degrees of similarity between separate sets of a same type of the feature information that have been respectively separated from the new information and the registered information, the new information being the hybrid feature information newly generated by the feature combining portion, the registered information being the hybrid feature information stored in advance in the feature information storage portion; and a determination portion that, based on the plurality of degrees of similarity computed by the plurality of similarity computation portions, determines whether the biometric information on which the new information is based and the biometric information on which the registered information is based have been acquired from a same person.
