Iris recognition is one
of the most accurate of all biometrics technologies.
Iris scan biometrics employs the unique characteristics
and features of the human iris in order to verify
the identity of an individual. The iris is the
area of the eye where the pigmented or coloured
circle, usually brown or blue, rings the dark
pupil of the eye.
In Iris scan process a specialized camera is used.
This camera is been placed very closed to the
subject that is not more than 3 feet away. It
uses an infrared imager to illuminate the eye
and capture a very high-resolution photograph.
It takes one or two seconds and provides the details
of the iris that is recorded. Iris Scan process
is not been affected by the eyeglass and contactlenses.
Iris-scan technology has been used in ATM environment
in England, the US, Japan and Germany from 1997.
In these customer's iris data became the verification
tool for access to the bank account. Airports
have begun to use iris-scanning for such diverse
functions as employee identification/verification
for movement through secure areas and allowing
registered frequent airline passengers a system
that enables fast and easy identity verification
in order to expedite their path through passport
control.
