Technical Seminar on

BIOMETRIC IDENTIFICATION IN ATM’S Under the Guidance of P.V.R.K.MURTHY, M.Tech

Assistant Professor

Presented By

•Biometric ATM are used for wide range of applications like for

Banking, Coupons & Self service ATM. Biometrics ATM offer ATM type

interface along with at-least one Biometrics capture device like

Fingerprint Scanner, Iris camera, Palm/Finger Vein scanner , Face

recognition camera. They are often called Multi-Biometrics ATM, Wall

mount Biometrics ATM, Biometrics Devices / Machine.

•Most of the ATM in the past have been using ID cards to identify users

but with the wide acceptance of Biometrics , a new generation of

Biometrics ATM are being deployed for wide range of applications

worldwide.

INTRODUCTION

What is Biometrics ?

• The meaning of Biometrics comes from the Greeks.

Biometry = bio(life) + metry(to measure).

• Biometrics is the science and technology of measuring and

analyzing biological data.

• The first known example of biometrics in practice was a form of

finger printing being used in China in the 14th century.

• Biometrics refers to technologies that measure and analyze human

body characteristics such as DNA, fingerprints, eye retinas and

irises, voice patterns,facial patterns and hand measurments for

authentication purposes.

HOW BIOMETRICS WORKS ?

• Biometrics systems work by recording and comparing biometric

characteristics.

• When an individual first uses a biometric system, their identifying

features are enrolled as a reference for future comparison. This

reference may be stored in a central database or on a card (or both)

depending on the needs of the application.

• When biometric recognition is

required, the individual 's

biometric characteristics are

recorded again. This time

however, the identifying features

are compared by the system with

the stored reference to determine

if there is a close match

TYPES OF BIOMETRICS

HAND

• The three dimensional shape of a

person’s hand has several

advantages as an identification

device.

• Scanning a hand and producing a

result takes 1.2seconds.It requires

little space for data storage about 9

bytes which can fit easily magnetic

strip credit cards.

FINGER PRINT

A fingerprint scanner system has two basic jobs :

• It needs to get an image of your finger.

• It needs to determine whether the pattern of ridges and valleys in

this image matches the pattern of ridges and valleys in pre-scanned

images.

• Only specific characteristics, which are unique to every

fingerprint, are filtered and saved as an encrypted biometric key or

mathematical representation.

No image of a fingerprint is ever saved, only a series of numbers

(a binary code), which is used for verification. The algorithm

cannot be reconverted to an image, so no one can duplicate your

fingerprints.

BIOMETRIC SYSTEM

Identification:

• A one to many comparison of the captured biometric against a

biometric database in attempt to identify an unknown

individual.

Verification:

• A one to one comparison of a captured biometric with a stored

template to verify that the individual is who he claims to be.

• Verification is faster and performs better.

• In a verification, the user must first enter his or her identity to

the biometric system. User ID's can be forgotten and cards can

be lost, making access impossible. 

MULTIBIOMETRICS

INTEGRATING FACES AND FINGER PRINTS FOR PERSONAL

IDENTIFICATION

An automatic personal identification system based on fingerprints or

faces is often not able to meet the system performance requirements.

A MULTIMODEL BIOMETRIC SYSTEM USING FINGERPRINT,

FACE AND SPEECH

This system takes the advantage of the capabilities of each individual

biometric. It can be used to overcome some of the limitations of a single

biometrics.

•ATM Card frauds

•Use of ATM card duplicators

•Card sharing by family and friends

•Inability to trace the wrongful users

•ATM PINs can be shared on phone or recorded

using secret cameras

ISSUES IN CURRENT ATM NETWORKS

BIOMETRIC ATMS SOLVE THESE ISSUES & OFF

•Single/Multi factor Biometric Authentication:

Fingerprint, Iris, Face, Pal vein

•Multifactor Authentication: Card + PIN +

Biometrics

•Online or offline Authentication using smart cards

•Card less Authentication

•Biometrics is combination of card or PIN

APPLICATIONS OF BIOMETRIC ATM

• Banking & Finance

• Food coupons / Tickets / Canteen ATM

• Membership Verification ATM

• Transaction / Check Deposit ATM

• Self Service ATM

• Retail ATM

•while a criminal might be able to obtain a password illegally,

getting a user's fingerprints would be much more

complicated.

•In addition, contrary to traditional ID cards or badges, you

can't actually lose physical features, making maintenance

more cost efficient for the business or organization, and the

technology more convenient for users.

ADVANTAGES

•Biometric identification machines are traditionally more

expensive to buy than traditional ones.

•Biometric identification machines are not always entirely

accurate. For example, an individual with a cold may not be able

to identify himself using a voice identification device, and

people who gain or lose weight may suddenly lose access to a

place protected by a system analyzing facial features.

DISADVANTAGES

CONCLUSION

Biometric tokens are the safest means of preventing ATM frauds.

• The main reason for introducing biometric systems is to increase

overall security.

• Biometrics offers greater security and convenience than traditional

methods of personal recognition.

• In some applications, biometrics can replace or supplement the

existing technology. In others, it is the only viable approach.

• The biometric system is only one part of an overall identification or

authentication process, and the other parts of that process will play an

equal role in determining its effectiveness

ATMS OF THE FUTURE

Today’s biometric scanners go far beyond basic fingerprint recognition.

• In Poland and Japan, consumers are already using Hitachi's infrared

scanners that capture the unique pattern of capillaries in the finger and

hand.

• The most secure biometric technology uses a device designed to

perform an iris scan based on more than 2,000 unique measurement

points.

• According to developers, people and pets all over the world will be

connected to a system that uses iris scan identification within the next

decade.
