Being unique to every individual, the pattern of a human iris begins its shaping six months after the moment of the child’s birth. This process gets completed by the age of one, whereupon the iris pattern remains unchanged for life. More absolute than other biometrics, an iris is unlikely to be imitated.
Advantages of the iris-based biometric technology:
non-aggressiveness to an individual being verified: an individual just looks into the camera
automatic image processing and digital template generation for comparisons
very high reliability and accuracy of automatic comparisons.
