IRISCAN TECHNOLOGY FOR POSITIVE PERSONAL IDENTIFICATION

IriScan, Inc., under contract to the Defense Nuclear Agency, is developing an identification/ verification system capable of positively identifying and verifying individuals without physical contact or a person in the decision loop. The new technology, using the unique patterns of the human iris, shows promise of overcoming previous biometric shortcomings and providing positive identification of an individual without contact or invasion, at extremely high confidence levels. The video-based system locates the eye and iris, zones the iris, and the features therein are encoded into a 256 byte (2048 bit) iriscode for enrollment or identification. The process is based on the unique nature and the extreme richness of the human iris. The multiple contraction furrows, collagenous fibers, crypts, coronas, striations, serpentine vasculature, freckles, rifts, and pits produce a non-duplicable organ with more than 435 degrees of freedom, or measurable variables. In comparison to the best Crossover Error Rates obtainable by current biometric technology of 1.5 to 3%, the IriScan calculated rate of 0.00076% represents a quantum leap forward for positive personal identification.
