Biometrics

The term "biometrics" is derived from the Greek

words bio (life) and metric (to measure).

In other words we can say that biometrics are technologies for measuring and analyzing a person's physiological or behavioral characteristics. These characteristics are unique

to individuals hence can be used to verify or identify a person.

INTRODUCTION

Based on Passwords, or ID/Swap cards

Can be Lost. Can be forgotten. Worse! Can be stolen and used by a thief/intruder to access your data,

bank accounts, cards etc….

Some Examples of DifferentBiometrics

Effectiveness

Criteria for selecting a biometrics system

Effectiveness : The basic measure of any authentication

solution is accuracy . Improper rejection of individuals who should have been successfully authenticated. It results in user frustration and time lost in reauthenticating must still be part of the measurement of overall effectiveness.

Effectiveness Ease of deployment and use

Criteria for selecting a biometrics system

Ease of deployment and use : No technology can be effective unless and

until Its operational and in regular use . The solution should be easy to deploy and maintain & shouldn’t require significant changes to business processes.

Effectiveness Ease of deployment and useEnterprise-wide capability

Criteria for selecting a biometrics system

Enterprise-wide capability : while an organization may deploy an

authentication solution to meet a single need today . It make sense early in the selection process to look at where and how the use of biometrics expanded to meet future needs .

Criteria for selecting a biometrics system

Economic consideration : Keeping cost under control is important

even when budgets aren’t under the strain they are today .

Criteria for selecting a biometrics system

Commercial applications such as computer network login , electronic data security , e-commerce, internet access, ATM , credit card, physical access control, medical records management and distance learning.

Government applications such as national ID cards, driver’s license , social security , border control and passport control.

Forensic applications such as corpse identification , criminal investigation and missing children.

Biometrics airport security devices are also deployed at some of the world’s famous airport to enhance the security standards.

Applications of biometrics system

a) Finger print verification system : - Manufactured by Digital persona - Used for Computer & network login. b)Fingerprint based point of sale (POS) terminal : - Manufactured by Indivos. - Verifies the customers before charging their credit cards & speed up payment in retail shops , restaurants & cafetrias .

c) Finger print based door lock -Manufactured by Bio thentica d) Immigration & Naturalization service accelerated service system (INSPASS) - Which is installed at major airports in U.S. is based on hand geometry verification technology.

e) Border passage system using iris recognition at london's heathrow airport.

f) Ben Gurion airport in Tel Aviv(Israel) - Uses express card entry kiosk fitted with Hand geometry System for security and immigration .

Identification:– Match a person’s biometrics against a database to figure out his identity by Finding the closest match .– Commonly referred to as 1:N matching– ‘Criminal Watch-list’ application scenarios .

Applications and terminology

Verification:– The person claims to be ‘John’, system must match and compare his/hers biometrics with John’s stored Biometrics.– If they match, then user is ‘verified’ or authenticated that he is indeed ‘John’– Access control application scenarios.– Typically referred as 1:1 matching

Applications and terminology

1) Iris-based ATM

2)Smart card with fingerprints

3)Fingerprint at check-out counter

4)Face scan at airports

Advantages of biometrics systemEnhanced securityCan’t copiedCan’t be share Convenience/controlAccuracyCan’t be lostReduced paper workCosts

1) Recognition errors : There are two types of recognition errors first

is False accept rate (FAR) and second is False Reject rate (FRR). A false Accept is when a non matching pair of biometrics data is wrongly . False Reject is when a matching pair of biometrics data is wrongly rejected.

2) Compromised biometric data : Paradoxically , the greatest strength of

biometrics is at the same time its greatest liability. The pattern such as Iris , Retina or palm vein remain the same throughout your life. So user has a limited no. of biometric features.

3) Attacks : There are so many Ways to bypass

biometrics system Such as presenting fake biometrics or a

copy at sensor for instance a fake finger or fake mask .
