SYSTEMS AND METHODS FOR USER AUTHENTICATION USING EYE MOVEMENT AND PUPIL SIZE CHANGE MATCHING

A system for eye movement and pupil size change matching for user authentication includes an ocular sensor that is configured to sense eyes of a user and collect data indicative of the user's eye movement and pupil size changes. When a user's eyes are detected, the logic analyzes data collected by the ocular sensor in order to determine whether the sensed data match data extracted from a template defined by the eye movement and pupil size changes of an authorized user. If so, the user is authenticated and is permitted to access at least one restricted resource. As an example, the user may be permitted to access an application or sensitive data stored on a computer system or to access a restricted area, such as a room of a building.
