Biometric Iris RecognitionThe iris of the eye possess physical patterns unique to each person - no two irises are alike in the world. Iris-scan biometric systems can analyze over 200 points of the iris, including rings, furrows and freckles. Eyeglasses, contact lenses, and eye surgery does not change the characteristics of the iris. This method of identification is becoming widespread, and is only second behind using fingerprints for identification. To prevent fooling the system: Iris recognition systems often vary the light in order to see that the pupil dilates, so that a fake eye can't be used. |
