Abstract(in English)	Pattern authentication is a motion-based user authentication method where a user traces dots on a screen with his/her finger and it has been widely used for a unlock function on smart phones. The pattern authentication is user-friendly and easy to implement in smart phones; however, the security analysis of the pattern authentication is not sufficient in comparison with security analyses of other user authentication methods. In this paper, we model the pattern authentication, and then we explain the security analysis of the pattern authentication with basic and relaxed rules for patterns.
