A Graphical Authentication System Controlled by Eye Movement

Abstract

Graphical password is a potential alternative to the traditional alphanumerical password due to its advantages of recognition and memory in the security system. Eye movement, a natural interaction modality, is a promising tool to replace the keyboard and the mouse in authentication. This paper proposes a graphical authentication system controlled by eye movement. In this keyboard-less authentication system, the user’s eye movements were recorded by eye-tracker as the control signal to generate recognition-based graphical passwords. The user test study has been conducted to verify the availability and effectiveness of this keyboard-less graphical authentication system. It’s also shown that the efficiency could be improved as the user getting familiar with this system.
