We have already 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. In addition, the previous study has shown that it is not easy for illegal users to guess the meaning of the unclear pass-image even if a brief explanation of the pass-image is given with words. However, the system has a drawback that less visibility of unclear images can impede the legitimate users to recognize their pass-images, which will require a longer time for the authentication. Therefore we enhance our authentication system by giving a brief explanation of the pass-image as hint. It is expected that the hint is helpful only for the legitimate user, since illegal users can not understand the hint as confirmed in the previous study. This paper verifies the availability of the modified system through basic experiments. |
