Eye gesture blink password: a new authentication system with high memorable and maximum password length

Abstract

Authentication systems in which eye is used for entering the password are categorized into two gaze-based and gesture-based groups. In the accurate point-of-regard gaze measurements, a key subject with gaze-based authentication schemes is needed. Gesture-based systems are based on identifying the eye movement tracking, hence, there is no need to estimate the precise point of the user’s vision. Although gesture-based systems are superior to gaze-based methods, they are not appropriate and applicable in remembering the equivalent gesture of any suitable number due to the high memory overhead. This paper introduces the new Eye Gesture Blink Password authentication system (EGBP). The system is based on four basic ideas: system design, the algorithm of finding fixations without having to track pupils in all frames, allowing users to blink as part of the password and the new method of finding the user password using the angle formed between the fixations. EGBP has several basic advantages compared to existing authentication systems including the no need for a commercial eye tracker that lowers the system’s cost, removing the calibration step that increases the speed and requires less processing, and choosing a maximum length code that reduces the likelihood of the likeness of the selected password and increases security. The possibility of simply memorizing the password because of the possibility of blinking and user’s high-speed input is another advantage of this system.
