Abstract
A registration device, verification device, authentication method and authentication program that can improve the accuracy of authentication are proposed. A predetermined process is performed for an image signal obtained as a result of taking a picture of a image-capturing target which is given as an object for biometrics authentication and which is a predetermined part of a living body; a characteristic part of the image-capturing target is extracted from the image signal; the Hough transform is carried out by characteristic extraction means for the extracted characteristic part; a plurality of characteristic parameter points are extracted from a parameter point obtained as a result of the Hough transform under a predetermined extraction condition; and a determination is made as to whether the plurality of characteristic parameter points are those to be registered or to be compared with the registered one according to an angle component of the plurality of the characteristic parameter points.
