INTRODUCTION:

Biometrics is a technology whichis mainly used for the securitypurpose.

It is preferred over traditionalsecurity methods.

TRADITIONAL SECURITY METHODS:

Password in computer

Pin number in ATM card

Identity card

Driving license

DISADVANTAGE OF TRADITIONAL

SECURITY METHOD:

We may forget the password or pinnumber.

We may loss the identity card & drivinglicense.

DEFINITION OF BIOMETRICS:

Biometrics refer to the automaticidentification of a person based on his/her

physiological or behavioral characteristics.

8/7/2019 et 131 priya

PHYSIOLOGICAL:

Biometrics based on data derived fromthe measurement of a part of Personsanatomy.

for example:

Face location

Hand geometry

fingerprint verification

Retinal scan

BEHAVIORAL:

Biometrics based on data derived frommeasurement of an action performedby a person.

for example:

Voice recoganization

Signature verification

BIOMETRICS :HOW DO THEY WORK?

Although biometric technologies differ, they all

work in a similar fashion:

� The user submits a sample using acquisition

device.

� Sample is then compared with the sample which

is already present in database.

� If it matches, it shows it is correct otherwise it isincorrect.

LEADING BIOMETRIC TECHNOLOGY:

� Facial recognization

� Fingerprint matching

� Hand geometry

� Voice recognization

� Signature scan

FACIAL RECOGNIZATION SYSTEM:

A facial recognization system is acomputer-driven application for automatically

identifying a person from a digital image.

It does that by comparing selected facialfeatures in the live image and a facialdatabase.

It is typically used for security systems and

can be compared to other biometrics such asfingerprint or eye iris recognition systems.

FINGERPRINT IDENTIFICATION:

Among all the biometric techniques, it isthe oldest method which has beensuccessfully used in numerous

application. The uniqueness of a fingerprint can be

determined by the pattern of ridges &furrows as well as the minutiae points.

APPLICATION OF BIOMETRICS:

It is used in forensic lab for criminalsidentification.

It is used to prevent unauthorized access toATM card, smart card & computer.

In automobile, biometrics can replace keyswith key less entry & key less ignition.

Due to increased security threats, many

country have used this technique for bordercontrol & national ID CARDS.

CONCLUSION:

Biometric cannot be lost, stolen orforgotten.

it cannot be written down and stolen bysocial re-engineering.

Thats why this technology is more

secure than others.
