Abstract: Identification of a human is a goal as ancient as humanity itself. As technology and services are evolving in the modern world, human activities and transactions have to proliferate in which rapid and reliable personal identification/authentication is required. The examples include passport control, computer login control, bank automatic teller machines, premises access control and security systems, etc. All such identification efforts share the common goals such as speed, reliability and automation. Biometrics for identification/authentication purposes requires the particular biometric factor is unique for each individual and it can be readily measured and also to be invariant over time. Biometric traits such as signatures, face, iris, fingerprints, voiceprints, retinal and blood vessel patterns can be used. Compared to other traits, human iris on the other hand as an internal organ of the eye well protected from the external environment, easily visible from within 1 m of distance makes it a perfect biometric trait for an identification/authentication system with the ease of speed, reliability and automation.
