A Ogle Sign-Based User Authentication System to Counter Shoulder-Surfing Attacks

Shoulder surfing helps to gain the authentication details of a victim to attacker through observations and nowadays it is becoming a very big threat to visual privacy. We present DyOglePass: Dynamic Ogle Passwords, an authentication strategy that uses dynamic ogle sign. Here we present two authentication interfaces, a dynamic and a static-dynamic interface, that helps this strategy to counter shoulder surfing attacks. The main idea is to authenticate the user by following uniquely colored circles that move along random paths on the screen. After so many 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 by comparing it to a ogle- and PIN-based authentication system. Finally, we found that the static-dynamic interface with a transition speed of two seconds was the most effective authentication method with a greater accuracy.
