Methods to Eye Gaze Interaction for Authentication

One of the methods touted to reduce shoulder surfing during onscreen authentication is eye gaze input. Eye gaze authentication methods have thus far relied on a few methods for selection of on screen objects, namely dwell time, blinking, eye gestures and pursuit of moving objects. This paper surveys the literature on the various approaches. From analysis of the advantages and drawbacks of the surveyed approaches, we find that the dwell method has advantages in security and usability. We then describe a method designed previously by the authors that enhances the dwell method by making use of peripheral vision. The proposed method is in the ideation stage.
