Iris scanning on the hoof

Iris-recognition system is the first to identify people on the move. Existing systems take several minutes to complete a single scan

THE world’s first iris-recognition system designed to identify people on the move has been unveiled.

Similar in shape to airport metal detectors, the Iris on the Move system can identify 20 people a minute as they file through. This makes it far more efficient than existing systems, which can take several minutes to complete a single scan.

Developed by the Sarnoff Corporation in Princeton, New Jersey, it uses a high-resolution camera and extra-bright infrared LEDs to illuminate the subject. A newly developed algorithm separates the image of the eye from the rest of the face.

Conventional iris-recognition software then separates the iris from the pupil, eyelashes and eyelid, and converts the image into a 2048-bit code.
