Claim One:
1. A system for continually verifying the identity of an eye observing a computer screen, comprising: a biometric database that stores topographic data about the eye that determines an identity of the eye; a light source that illuminates the eye; a camera that images the eye and one or more reflections of the light source from the eye as the eye observes a screen over time; and a processor in communication with the camera and the biometric database that calculates an angular orientation of an optical axis of the eye from an image of the eye and the one or more reflections of the light source from the eye, identifies an irregularity on a surface of the eye from the one or more reflections of the light source in the image, determines the location of the irregularly on the eyeball from the angular orientation, and compares the irregularity to the topographic data in the biometric database using the location to verify an identity of the eye.
