INTRODUCTION
Many fields in the world requires authentication of the users
We use authentication in day-today life
Most authentications are protected only by “passwords”
Eg : e –mail, face book
Passwords are known to be one of the easiest target of
hackers. So the authentication is easily broken
Solution:
Biometric Authentication

Image Acquisition And Segmentation
Image Acquisition
The iris image is acquired
from camera
Camera is placed 9 cm away
from subjects eye
The source of light is placed
at a distance of 12 cm (approx)
from the user eye
The distance between source
of light and camera is found to be
approximately 8 cm

Segmentation
The isolation and excluding of specular reflections that corrupt
the iris pattern and locating the circular iris region can be done
by using the following technique:
Hough Transform
Daugman Integro-Differential operator

Image Normalization
Normalizing iris from an image delineates the annular
portion from the rest of the image.
The annular ring is transformed to rectangular ring.
The coordinate system is changed by unwrapping the iris
from Cartesian coordinate their polar equivalent.

Database template (S) is matched with the query
template (T) using Hamming distance approach
HD= ||(code A XOR code B) AND (mask A AND mask B)||||( mask A AND mask B)||
Pattern Matching
Where,
{code A, code B} are phase code vectors bit
and {mask A ,mask B} are mask bit vectors.
The Iris Code derived from this process is compared
with previously generated Iris Code

Advantages
Highly protected, internal organ of the eye.
No need for a person to touch any equipments.
Genetic independence no two eyes are same.
An iris scan is similar to taking a photograph and can be
performed from about 10 cm to a few meters away.
Encoding and decision making are tractable.
