摘要：
A biometric authentication device includes: a matching data generating unit which generates matching data from at least one biometric image representing a plurality of pieces of biometric information of a user; a mutual biometric information feature amount extraction unit which extracts a mutual biometric information feature amount representing the degree of similarity between two pieces of biometric information of the plurality of pieces of biometric information; a selection unit, which, for each of the first predetermined number of the registered users, computes a first selecting score based on the mutual biometric information feature amounts of the user and the registered users and selects the second predetermined number of registered users in order of decreasing the level of similarity based on the first selecting score of each registered users; and a matching unit which matches the matching data of the selected registered users with the matching data of the user.
