| Outline of Final Research Achievements |
Users of smartphones and/or tablet computers browse and download confidential document
files routinely. Therefore, the higher security level is needed for smartphones and tablet computers than conventional mobile phones (feature phones). In this study, we proposed a user authentication method for touch screen devices that is resistant to smudge attacks, which guesses authentication pattern from dirt on the screen. We actually implemented it as an application for smartphones. The proposed method is an image authentication method that uses images taken by users themselves as pass images, and is also resistant to observation attacks and recording attacks. In addition, we conducted various considerations on the success rate of authentication and attack resistance, and examined improvements to improve them.
