Abstract
An authentication device includes a comparison unit and a determination unit. The comparison unit compares, with feature value master data for authentication, each feature value needed for authentication that has been extracted from a plurality of pieces of acquired biometric information. The determination unit determines not to provide authentication when, as a result of comparison by the comparison unit, there is no difference in each of the feature values that resulted in a mismatch.
