The use of the iris for biometric authentication is relatively new. All the current commercial algorithms are based on the original patented algorithm from John Daugman at the University of Cambridge. In 1994, the iris engine was ready and available for licensing. Since then, Iridian Technologies has purchased the algorithms and associated rights. Iridian Technologies has licensed other companies to build applications that leverage the iris algorithms.
Iris biometrics offer the promise of the Holy Grail of biometrics. A strong, reliable biometric trait is measured, generating a template that is simple to compare and provides virtually no FAR. There is also an extremely low FRR of 0.2% in three attempts.
