A PRESENTATION ON

BIOMETRICS


2/18

is the technique of using

unique, non-transferable, physicalcharacteristics, such as fingerprints, togain entry for personal identification.This replaces pin codes and passwords,which can be forgotten, lost or stolen.Biometric IDs cannot be transferred.

NEED OF BIOMETRICS!!

Now-a-days we are facing majority ofcrimes related to security issues and these

arise due to the leakage of passwords orillegal authentication.

At one end, there is a continuous and

tremendous improvement in the lifestyle ofHumans while at the other end; thetechnological crimes are increasing rapidly.


4/18

THERE must be a solution ???

Technologies capable of identifying each person uniquelyneed to be developed. The only powerful solution for the

problem of illegal authentication is Biometrics.

METHODOLOGIES OF BIOMETRICS

RETINA

An established technologywhere the unique patterns of the

retina are scanned by a low

intensity light source via an

optical coupler


6/18

FACE RECOGNITION

Facial scanning involves

scanning of the entire face

and checking of critical pointsand areas in the face with thetemplate. This method is not

completely reliable and so it

is used in association withanother biometric technique


7/18

SIGNATURE RECOGNITION

Signature verification devices

have proved to be reasonably

accurate. . Signatureverification analyzes the way

a user signs her name.

Signing features such as

speed, velocity, and pressureare as important as the

finished signature's static

shape

Voice recognition

Voice authentication is notbased on voice recognition buton voice-to-print

authentication, where complextechnology transforms voiceinto text. Voice biometrics hasthe most potential for growth,

because it requires no newhardwaremost PCs alreadycontain a microphone.


9/18

Hand recognition

Hand geometry is concerned withmeasuring the physical characteristicsof the users hand and fingers, HandGeometry scanning systems scan the

size, length, thickness and surface of ausers hand (including fingers), in orderto verify the user. Unlike otherbiometrics, such as fingerprints andretina scanning, hand geometry

cannot be guaranteed as unique;hence, hand geometry is not anidentification technique, but rather averification technique.


10/18

Finger print verification

Finger based scanning is oneof the oldest methods usedfor verification. Fingerprints,unique and immunable for allare made of series of ridgesand furrows on the surface ofthe finger. These ridges and

furrows determine theuniqueness of thefingerprints.

How does it works

Whilst individual biometric

devices and systems

have their own operating

methodology, there are

some generalisations one

can make as to what

typically happens within abiometricsystems

implementation.


12/18

Biometrics implementation

Obviously, before we can verify an individuals

identity via a biometric we must first capture a

sample of the chosen biometric. This sample isreferred to as a biometric template and is thereference data against which subsequent

samples provided at verification time are

compared. A number of samples are usuallycaptured during enrolment (typically three) in

order to arrive at a truly representative template

via an averaging process.


13/18

The template is then referenced against anidentifier (typically a PIN or card number if used in

conjunction with existing access control tokens) inorder to recall it ready for comparison with a live

sample at the transaction point.

IT INVOLVESStoring the template within biometric device

The verification process requires the user to claim an identity by

either entering a PIN or presenting a token, and then verify thisclaim by providing a live biometric to be compared against theclaimed reference template. There will be a resulting match or nomatch accordingly .

advantages

Biometric identification provide a unique identification.Biometrics is more reliable and efficient in distinguishing

between a specific individual and an imposter.

Biometric identification protects customers against theft

and fraud.Identification of the individuals is based on the individuals

unique physical and biological qualities that can not be

traded, shared, lost or stolen

It is much efficient than the (PIN) personal identification

number or token-based authentication techniques.

After all it cant be forgotten or lost.


16/18

disadvantages

Biometric system may not give an accurate identification.

Cost of the implementation tools is too high (such as finger print

sensors are extremely expensive).

The cost of the storing biometric templates and of the computing

power required to process and match biometric measurement is quite

high.

There are some techniques like DNA profiling which is complicated

and time taking process.

Change of hair style in facial recognition, wearing glasses, and light

intensity in retina scanning may effect the authentication process.


17/18

Future enhancement

The application of biometrics in near future will be in ATM Machineswhere the leading banks will use biometrics as a general means of

combating card fraud.

Apart from these this technology is going to make place in internettransaction, telephone transaction, and will be used as public identity

cards.

Some vendors have built a fingerprint sensor directly into

the smart card reader, which in turn passes the biometric tothe smart card for verification.


18/18

conclusion

At its infancy, current biometric technology is stillconsidered immature to completely replace password andother authentication schemes

Although the challenges confronting biometrics aremany, none of these is going to stop the progress ofbiometrics being used as authentication and identificationtools

A wiser approach would be to prepare the peoplementally and psychologically for the new technology, makefurther improvements to the technology
