Gaze-based Password Entry Systems

Graphical passwords have been demonstrated to be the possible alternatives to traditional alphanumeric passwords. However, they still tend to follow predictable patterns that are easier to attack. Cued Gaze-Points (CGP) is presented as a shoulder-surfing resistant cued-recall graphical password scheme where users gaze instead of mouse-click. This approach has several advantages over similar eye-gaze systems, including a larger password space and its cued-recall nature that can help users remember multiple distinct passwords. However, they found graphical passwords a bit more complex and difficult to learn how to use them, something that they can overcome with small practice.
