INTRODUCTION
❖Biometrics is the science of human recognition.
In biometrics, "Iris & Retinal Scanning” technologies
are known as “ocular based” identification technologies,
meaning they rely on unique physiological characteristics
of the eye to identify individual.
❖Retinal scanning is the analysis of the blood vessels
at the back of the eye.
❖Iris scanning takes a reading of the characteristics of
the iris.

PROJECT OBJECTIVE
❑Characteristics of the Iris make it very attractive for
use as biometric.
❑The unique iris pattern from a digitized image of the
eye is encoded into a biometric template, and then
stored in a database.
❑A biometric template contains an objective mathematical
representation of the unique information stored in the iris
and allows comparisons between templates.

FEATURES OF THE PROJECT
The iris of the eye has been described as the ideal part of
the human body for biometric identification for several
reasons:
✓ It is an internal organ that is well protected against damage and wear by a
highly transparent and sensitive membrane (the cornea). This distinguishes it
from fingerprints, which can be difficult to recognize after years of certain
types of manual labor. The iris is mostly flat, and its geometric configuration is
only controlled by two complementary muscles (the sphincter pupillae and
dilator pupillae) that control the diameter of the pupil.
✓ The iris has a fine texture that like fingerprints is determined randomly during
embryonic gestation. Like the fingerprint, it is very hard (if not impossible) to
prove that the iris is unique. However, there are so many factors that go into
the formation of these textures that the chance of false matches for either is
extremely low. Even genetically identical individuals have completely
independent iris textures. An iris scan is similar to taking a photograph and can
be performed from about 10 cm to a few meters away.

ACKNOWLEDGEMENT
I would like to express my gratitude to our guide Mr. Dipra Mitra(In-
Charge of DCST) and Dr. Abhijit Chakraborty(Principal) who
gave me the opportunity to do this project ,which also helped me in
doing a lot of research and I came to know about so many things, I am
really thankful.
I am also proud of all my friends and family members, for their
continuous encouragement and help and support at all the stage of my
endeavour, without that active co-operation this project would not
have seen the light of success.
