Abstract
A hybrid biometric authentication device that includes 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, a feature information storage portion that stores the hybrid feature information, a plurality of similarity computation portions that separates each of new information and registered information into the plurality of types of feature information, and compute a plurality of degrees of similarity between separate sets of a same type of the feature information, and a determination portion that, based on the plurality of degrees of similarity, 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.
