Gesture authentication with touch input for mobile devices

Abstract

The convergence of our increasing reliance on mobile devices to access online services and the increasing number of online services bring to light usability and security problems in password entry. We propose using gestures with taps to the screen as an alternative to passwords. We test the recall and forgery of gesture authentication and show, using dynamic time warping, that even simple gestures are repeatable by their creators yet hard to forge by attackers when taps are added. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
