Outline of Final Research Achievements

The existing mobile terminal authentication schemes not have the resistance of shoulder-surfing attack. We studied user authentication method with peeping resistance and usability. The user authentication method with peeping resistance is a problem of increasing the user's memory burden due to complication of the input method. Also, it is a problem that authentication information is extracted by record analysis by a video recording device such as a camera.
In this paper, we proposed and implemented several user authentication schemes with peeping tolerance and high usability. We proposed the STDS authentication method to tap the icon using our own movement rule "shift" and puzzle authentication method to prepare for password specified position. In addition, we suggested rhythm authentication that allows users to confirm their identity by tapping the screen in a pocket or bag. We implemented each method on Android terminal and evaluated about peeping resistance and usability.
