A STUDY ON USER AUTHENTICATION BASED ON ARM MOVEMENTS USING AN ACCELERATION SENSOR

By Madoka Hasegawa, Daisuke Someya, Yuichi Tanaka and Shigeo Kato

Abstract

In this paper, we study a user authentication method using a handy controller with a built-in acceleration sensor. For the authentication, a user draws a figure in the air with holding the controller. If the captured data by the acceleration sensor during moves of his/her arm are matched with user’s data stored in the system, the user can access the system. Although drawing a figure in the air is easy and convenient for logging on to video games and applications in mobile terminals, this method is vulnerable against observation attack because user’s movement is observable. Attackers may success in impersonating the movement. To solve this problem, we utilize both of log data of the acceleration sensor while drawing a mark and movement to press/release a button behind the controller. Observing the motion to press/release the button is difficult for attackers. This method is expected to be stronger than the former method against the impersonation attack. Index Terms — user authentication, acceleration sensor, behavior-based approach, security. 1
