Why iris recognition?
Iris recognition is particularly attractive for security applications since the iris is an extremely reliable identifier of an individual. However, the biggest technical hurdle standing in the way of the widespread deployment of these systems is obtaining accurate images in a simple manner that is “user friendly” to the widest range of people. Current systems only operate at short ranges and often users have great difficulty in positioning themselves properly, which leads to either poor images or no image at all being captured.
