Abstract

Abstract A plurality of iris images of a person to be authenticated in which the positions of extraneous light reflection are respectively different are captured by using an image capturing device. Iris codes, that is, features for authentication, are respectively extracted from the plural iris images, and the plural iris codes thus extracted are respectively compared with a registered iris code, so as to generate a plurality of comparison results. The plural comparison results are integrated to obtain an ultimate comparison score, which is used for the authentication.
