BIOMETRIC RECOGNITION

TECHNOLOGIES AND APPLICATIONS

AUTOMATED PROCESS OF IDENTIFYING

What is Biometrics ?

Biometrics

Biometrics" is derived from the Greek words 'bios' and 'metric which

means “life measurement" in other way , Biometry = Bio(life)+ Metry

(to measure).• Is the term given to the use of

biological traits

OR

behavioral characteristics

to identify an individual.

Biometrics: “bio”means life and “metrics”– to measure.

Characteristics of Biometrics

Biometric technology measuring and analyzing biological data of human body, it’s capture & identify automatically through integrated biometric device which based on two major characteristics .

1. Physical characteristics

2. Behavioral characteristics

Mode of Biometric System

Identification

One-to-many comparison

It search for a sample against a database of templates

It identifies an unknown individual.

For e.g.: who is “x”?

Verification

One-to-one comparison

It compares a sample against a single stored template

It verifies that the individual is who he claims to be

For e.g.: is this “x”?

How Does a Biometric System

Work?

Biometrics is a method of *direct* human identification.

Biometric access control systems, providing strong security atentrances.

Biometrics help to no need to remember passwords, or PINs.Biometrics cannot be lost, stolen or forgotten

Automated identification can be done very rapidly anduniformly, with a minimum of training.

• Discourages fraud

• Enhances security

Why Use Biometrics?

Applications of Biometrics

Technology

Fingerprint Identification

Fingerprint recognition is amethod of biometricauthentication that usespattern-recognitiontechniques based onimages of human fingervein patterns beneath theskin's surface. Finger veinrecognition is one of manyforms of biometrics used toidentify individuals andverify their identity.

Fingerprint Recognition Process

Fingerprint Technology Uses

Door Locks

Access Control

Computer work

stations

Time Clocks

In room safes

Payment Systems

Hand Geometry

Person identification using hand geometry utilizes handimages to extract a number of features such as fingerlength, width, thickness, finger area etc. Scan hand surfacearea-to verify that the person using the device is really whohe or she claims to be.

Work Of Hand Geometry

System

The user places the palm of his hand on a metal surface which has guidance pegs on it.

the device can reads the hand attributes.

The device then checks its database for verification of the user.

The process usually takes less than 5 seconds.

Facial Recognition

Facial recognition systems

Face Recognition is physiological characteristics of human that identify by predefine computer programs and analyze human faces for the purpose of identifying them. These include the position/size/shape of the eyes, nose, cheekbones and jaw line.

Facial Recognition Process

Facial recognition systems

Voice Recognition

Voice recognition system Ituses the pitch, pattern,tone, frequency, rhythm ofspeech for identificationpurposes.

A telephone or microphonecan act as a sensor.

Speaker recognition is oftenused where voice is theonly available biometricidentifier, such astelephone.

Biometrics Iris Recognition

There are two different types of eye scans: retinal andiris, It measures the iris pattern of the eye i.e. thecolored part of the eye that surrounds the pupil.

The iris scanner analyzes features like rings, furrows,and freckles existing in the colored tissue surroundingthe pupil.

Signature verification

Signature recognition is a behavioral biometric.

Signature to identify note the angle at which the pen isheld, and count number of times the pen is lifted andhow much time it takes to write the entire signature

Actual signature recognition is carried out by writing on apressure sensitive pad with a pen or stylus.

Advantage of Biometrics

Biometric identification can provide extremely accurate,

secured access to information; fingerprints, retinal and

iris scans produce absolutely unique data sets when

done properly

Current methods like password verification have many

problems (people write them down, they forget them,

they make up easy-to- hack passwords)

Automated biometric identification can be done very

rapidly and uniformly, with a minimum of training.

Disadvantage of Biometrics

The finger print of those people working in Chemical industries is often affected. Therefore these companies should not use the finger print mode of authentication.

Biometrics is an expensive security solution.

For people affected with diabetes, the eyes get affected resulting in differences.

It is found that with age, the voice of a person differs. Also when the person has flu or throat infection the voice changes or if there are too much noise in the environment this method may not authenticate correctly. Therefore this method of verification is not workable all the time

Conclusion

Biometric Solution read Biological factor anddigitally identify human nature.

Biometric Technology is very inexpensive and easyto use for many application area.
