abstract
2018 IEEE. Shoulder surfing enables an attacker to gain the authentication details of a victim through observations and is becoming a threat to visual privacy. We present DyGazePass: Dynamic Gaze Passwords, an authentication strategy that uses dynamic gaze gestures. We also present two authentication interfaces, a dynamic and a static-dynamic interface, that leverage this strategy to counter shoulder surfing attacks. The core idea is, a user authenticates by following uniquely colored circles that move along random paths on the screen. Through multiple evaluations, we discuss how the authentication accuracy varies with respect to transition speed of the circles, and the number of moving and static circles. Furthermore, we evaluate the resiliency of our authentication method against video analysis attacks by comparing it to a gaze- and PIN-based authentication system. Overall, we found that the static-dynamic interface with a transition speed of two seconds was the most effective authentication method with an accuracy of 97.5%.
