Introduction
Iris recognition is a method of
biometric authentication that uses pattern recognition techniques based on
high-resolution images of the irises of an individual's eyes. Not to be
confused with another less prevalent ocular-based technology, retina scanning,
iris recognition uses camera technology, and subtle IR illumination to reduce
specular reflection from the convex cornea to create images of the detail-rich,
intricate structures of the iris. These unique structures converted into
digital templates, provide mathematical representations of the iris that yield
unambiguous positive identification of an individual.
Iris recognition efficacy is rarely
impeded by glasses or contact lenses. Iris technology has the smallest outlier
(those who cannot use/enroll) group of all biometric technologies. The only
biometric authentication technology designed for use in a one-to many search
environment, a key advantage of iris recognition is its stability, or template
longevity as, barring trauma, a single enrolment can last a lifetime.
Breakthrough work to create the iris
recognition algorithms required for image acquisition and one-to-many matching
was pioneered by John G.Daugman, who holds key patents on the method. Daugman's
algorithms are the basis of almost all currently (as of 2006) commercially
deployed iris-recognition systems. It has a so far unmatched practical
false-accept rate of zero; that is there is no known pair of images of two
different irises that the Daugman algorithm in its deployed configuration
mistakenly identifies as the same.
We
will use IRIS authentication technique to control the hardware in our project.
The hardware can either be a electro-mechanical lock, generator, access panel,
ATM, etc.
