AUTHENTICATION METHOD USING MULTI-FACTOR EYE GAZE
First Claim
1. Apparatus for authenticating a user of a mobile device comprisinga camera of the mobile device for capturing an image of an eye of the user of the mobile device, the camera providing an output to a processor of the image of the eye,the processor for locating the pupil of an eye within the eye image, for calculating a direction of gaze of the eye of the user and for providing an output indicating the direction of gaze to a memory of the mobile device, anda display for displaying an indication of the direction of gaze of the user indicative of a means for authenticating the user to the mobile device.

Abstract
A method for rapid and robust one-step multi-factor authentication of a user is presented, employing multi-factor eye gaze. The mobile environment presents challenges that render the conventional password model obsolete. The primary goal is to offer an authentication method that competitively replaces the password, while offering improved security and usability. This method and apparatus combine the smooth operation of biometric authentication with the protection of knowledge based authentication to robustly authenticate a user and secure information on a mobile device in a manner that is easily used and requires no external hardware. This method demonstrates a solution comprised of a pupil segmentation algorithm, gaze estimation, and an innovative application that allows a user to authenticate oneself using gaze as the interaction medium and biometrics to authenticate an individual'"'"'s facial structure.
