title = "Gaze based user authentication for personal computer applications",
abstract = "This paper presents a simple PIN-like approach to user authentication, using the gaze sequence of an observer when presented with a previously-seen image on a personal computer screen. The method relies on the principle that the human visual system requires the eye to rest motionless for short periods, to assimilate detail at a given location in a visual scene. By deliberately looking at certain features or objects in a scene following a pre-defined sequence specified by the observer, an independent signature for personal identification can be established. Points of gaze fixation can be identified using a simple eye-tracker based on images from a typical webcam, and processed to extract a compact representation of the significant screen locations from the gaze sequence. Experimental results demonstrate that these {"}signatures{"} can be reliably and rapidly computed, and offer the advantage that they are difficult to detect by covert means.",
