| Abstract(in English) | We have recently proposed an user authentication system using "unclear images" as pass-images, in which only the legitimate users can understand their meanings by viewing the original images corresponding to the unclear pass-images. These unclear images are meaningless for illegal users. Hence it is difficult for illegal users to remember the unclear pass-images, even though they observe the legitimate users' authentication trial. This paper reports another advantage of the user authentication system using unclear images; the adaptation of unclear images enables the automatic generation of the decoy images which are displayed along with pass-images in the authentication window. Here, we explore the way of the automatic generation of decoy images. |
