•

•It performs automatic identification of a person

based on his/her physiological characteristics.

• Biometrics is the science of measuring physical or anatomical characteristics of individuals.

•Iris Recognition

•Fingerprint Recognition

•Voice Recognition

•Signature Recognition

•Face Recognition

•The iris is the colorful part of the eye between the white sclera and the pupil.

•Iris is the only internal organ of the human body that is normally externally visible.

•The iris identification program may be divided into

four main functional blocks:

1.Image Acquisition.

2.Preprocessing.

3.Image Analysis.

4.Image Recognition.

•The acquired image always not only “useful” parts

(IRIS), but also some “irrelevant” parts

e.g. eyelid, pupil .

•So the preprocessing is composed of two steps:

1.Iris Localization.

2.Edge Detection.

•In this stage, we should determine iris part of the image by localizing the position of the image derived from inside the limbus (outer boundary) and outside the pupil (inner boundary), and finally convert the iris part into a suitable representation.

•It is used to find complex object boundaries by marking potential edge point corresponding to places in an image where rapid change in brightness occurs.

•In other words, edge is defined by the discontinuity in gray values. An edge separates two distinct objects.

•The features of the iris are then analyzed and

digitized into a 512 byte (4096 bits) Iris Code

record.

•In this iris code half of the describes the features

and another half of the describes the control the

comparison process.

1.A person stands in front of the iris identification system,

between one and three feet away, while a wide angle

camera calculates the position of their eye.

2.A second camera zooms in on the eye and takes a black

and white image.

3.Once the iris is in focus, it overlays a circular grid on the

image of the iris and identifies the light and dark areas,

like an “eye print”.

4.To prevent a fake eye from being used to fool system,

these devices may very the light shone into the eye and

watch for pupil dilation.

•FAR - As low as 1 in 1,000,000

•FRR –around 2%

1.Highly Protected Internal Organ Of The Eye.

2.Externally Visible Patterns Imaged From A

Distance.

3.Pattern Apparently Stable Throughout The Life.

4.Image Analysis And Encoding Time: 1 Seconds.

5.Search Speed: 1,00,000 Iris Code Per Second.

1.Computer login: the iris as a living password.

2.National border controls: the iris as a living passport.

3.Driving licenses and personal certificates.

4.Internet security.

5.Premises access control (Home, Office, Laboratory).

6.Anti-terrorism (e.g. security screening at airports)

7.Financial Transactions (electronic commerce and

banking).

8.Secure accesses to bank cash machine accounts.

•Iris recognition system 1.0

•Iris application server 2.0

•Iris 3D 1.0.8

•Biometric technology has great potential

•There are many biometric products around, regarding the different biometric technologies

•Since September 11th, biometric products are pushed forward

•Shortcomings of biometric systems due to oManufacturers ignorance of security concernsoLack of quality controloStandardisation problems

•Manufacturers have to take security concerns serious
