FEASIBILITY STUDY

Feasibility is a test of the proposed system according

system according to workability, impact on the organization

ability to meet user needs and effectiveness use of

resources. following are the feasibility study employed:

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:

Iris Recognition

The iris is the colored ring of textured tissue that surrounds the pupil of the eye.

Stages Involved In Iris Detection

• It includes mainly the

three stages:

Acquisition and

Segmentation

Image Normalization

Pattern Matching

FEASIBILITY STUDY








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

FEASIBILITY STUDY








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

FEASIBILITY STUDY








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.

FEASIBILITY STUDY








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

FEASIBILITY STUDY








Performance

False accept rate (FAR).

False reject rate (FRR).

Equal error rate (ERR).

Failure to enroll rate (FER).

Failure to capture rate (FCR).

FEASIBILITY STUDY








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.

FEASIBILITY STUDY








Disadvantages

The accuracy of iris scanners can be affected by

changes in lightning.

Well trained and co-operative user is required

FEASIBILITY STUDY








Applications

Used in airports for security purposes.

Computer login: iris as a living password.

Credit card authentication.

Secure financial transaction.

Forensics, birth certificates, tracking missing or

wanted person.

FEASIBILITY STUDY








Conclusion

The field of biometrics is evolving.

Increase the overall security.

Decreasing costs and increasing convinence.

Increasing both privacy and identity security.
