HOW IRIS RECOGNITION WORKS John Daugman, OBE University of Cambridge, The Computer Laboratory, Cambridge CB3 0FD, U.K. ABSTRACT The principle that underlies the recognition of persons by their iris patterns is the failure of a test of statistical inde-pendence on texture phase structure as encoded by multi-scale quadraturewavelets How iris recognition works Abstract: Algorithms developed by the author for recognizing persons by their iris patterns have now been tested in many field and laboratory trials, producing no false matches in several million comparison tests The key to iris recognition is the failure of a test of statistical independence, which involves so many degrees-of-freedom that this test is virtually guaranteed to be passed whenever the phase codes for two different eyes are compared, but to be uniquely failed when any eye's phase code is compared with another version of itself

Iris recognition algorithms work by locating and extracting the iris circular area from the photo of the full eye region, followed by comparing iris areas, from two different captures, using mathematical pattern recognition techniques. Since the iris can vary in size, as the pupil dilates or shrinks, adjustments are made to allow for these changes Look, scan - authorized. Done. Iris recognition technology is exciting many industries that require safe and easy authorization. What is it? How does it work..
