System and method for providing secure access to an electronic device using continuous facial biometrics

摘要

A facial biometric recognition system and method (100) for providing security for an electronic device (101) includes a digital camera (105) having a field of view for providing facial biometric images at a predetermined interval from a user of the electronic device (101). A processor (109) is associated with the electronic device (101) for comparing the facial biometric images to biometric image data stored in a database (107). The facial biometric images are continuously compared (111) to those stored in the database (107) or to facial image tracking (113) for providing substantially continuous authentication when the user physically moves about the camera's field of view. The invention may be used with devices such as a personal computer (PC), mobile telephone, personal digital assistant (PDA) or gaming device and provides an efficient means by which to secure information on the device without the need for complex biometric security devices.
