algorithm
in 1991 while working at the University of Cambridge. The algorithm was first commercialized in the late 1990s. His algorithm automatically recognizes persons in real-time by encoding the random patterns visible in the iris of the eye from some distance, and applying a powerful test of statistical independence. It is used in many identification applications such as the Unique IDentification Authority of India (
UIDAI) for registering all 1.3 billion citizens of India for government services and entitlements, border crossing controls in
