Live gaze-based authentication and gaming system

Abstract

Face recognition has been widely applied to identification/ authentication systems [1–6], however, a considerable drawback of conventional face recognition when used alone lies in its limited ability to distinguish between living human user and 2D photos or pre-recorded videos of the user’s face. To address the risk of these systems being easily bypassed by non-living photos or recordings of users, our study proposes an interactive authentication system that requires users to follow a specific pattern displayed onscreen with their gaze. The system uses the subject’s eye movement and facial features during viewing for user authentication while randomly generating the displayed pattern in real time to ensure that no prepared video can fake user authentication. Given gaze movement is an inseparable part of the face, our system guarantees that facial and eye features belong to the same human following the pattern displayed. To this its deployment in an eye controlled system, we developed a gaze-controlled game that relies on user eye movement for input and applied the authentication system to the game.
