AUTHENTICATION APPARATUS AND METHOD FOR CONTROLLING THE AUTHENTICATION APPARATUS, ELECTRONIC DEVICE PROVIDED WITH AUTHENTICATION APPARATUS, PROGRAM FOR CONTROLLING AUTHENTICATION APPARATUS, AND RECORDING MEDIA STORING THE PROGRAM

摘要

The present invention aims to effectively prevent spoofing in authentication and maintain convenience of the user. In a face authentication unit of the portable telephone, the face image checking part checks the face image of the person to be authenticated, which is acquired by a face image acquiring part through a photographing unit, with face feature information contained in a face feature DB of the storage unit and calculates the matching degree. A threshold value determining section determines the threshold value by searching the evaluation DB based on the position information of the own device acquired by the position information acquiring section through the GPS receiver. An authenticating section compares the matching degree calculated by the face image checking section and the threshold value determined by the threshold value determining section, and determines success and failure of the face authentication.
