Using fingerprints has been accepted publicly for the reason of legal compulsion from a long time ago. In so far as this technology has been converted from a legal compulsion to a civil tool and also enjoys a commercial figure and a high share in the market and is used in number of functions. Delicacy and convenience of this process is to such an extent that even today with lots of progressions in other sectors like identification of voice, face and iris, the only fingerprint is accredited by the Judiciary for issuing final verdicts.
Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of the irises of an individual’s eyes, whose complex random patterns are unique and can be seen from some distance.
The automated method of iris recognition is relatively young, existing in patent only since 1994. Iris is one of three biometric identification technologies internationally standardized by ICAO for use in future passports (the other two are fingerprint and face recognition)
