User-Generated Free-Form Gestures for Authentication


Dr. Janne Lindqvist interdisciplinary security work, to appear in MobiSys'14, the tier-1 conference on mobile systems, is getting nice publicity around the world.

In that work, Prof. Janne Lindqvist and his students, Michael Sherman (former ECE undergrad, and currently WINLAB staff), Gradeigh Clark (ECE PhD student), Yulong Yang (ECE PhD student) and Shridatt Sugrim (ECE MS and WINLAB staff), collaborated with Prof. Antti Oulasvirta of Max-Planck Institute for Informatics and Teemu Roos of University of Helsinki, on a novel form of authentication for mobile devices. In particular, they studied user-generated free-form gestures and developed a novel information-theoretic for analyzing the security and memorability of the gestures. The group also built an actual authentication system designed for the gestures.
