Iris recognition:An algorithm of a person's universe?
Breakthrough work to create the iris recognition algorithms required for image acquisition and one-to-many matching was pioneered by John G. Daugman, Ph.D, OBE (University of Cambridge Computer Laboratory), who holds key patents on the method. These were utilized to effectively debut commercialization of the technology in conjunction with an early version of the IrisAccess system designed and manufactured by Korea's LG Electronics. Daugman's algorithms are the basis of almost all currently (as of 2006) commercially deployed iris-recognition systems. It has a so far unmatched practical false-accept rate of zero; that there is no known pair of images of two different irises that the Daugman algorithm in its deployed configuration mistakenly identifies as the same. (In tests where the matching thresholds are – for better comparability – changed from their default settings to allow a false-accept rate in the region of 10−3 to 10−4 , the IrisCode false-reject rates are comparable to the most accurate single-finger fingerprint matchers
