IRIS Recognition in UID

The iris of the eye is a protected organ, which controls the diameter of the pupils – the centre part of the eye – and the amount of light entering the eye. The front, pigmented layer of the iris contains random patterns that are visible and highly stable. These patterns are also highly intricate, and unique to every individual. The iris faces very little wear, and can consequently serve as a secure, always available passport that an individual can present for verification. The field of iris biometrics has seen significant research and investment over the last decade, and at this point, iris capture has become a mainstream technology with wide acceptance. In India, over 50 million people have been enrolled using iris recognition systems in Andhra Pradesh and Orissa. Feedback on these systems has been positive both from enrolling agencies and state government officials. Mexico is also using iris for its version of Unique ID to deliver public benefits to its entire population. De-duplication through iris has been carried out on a large scale – one implementation that de-duplicated the entry of immigrants into a country has carried out five trillion iris comparisons since 2001
