HISTORY OF BIOMETRICS

FRANCIS GALTON – 1892.

In 1968, Biometrics technique was implem-

ented in New York bank.

But after1990, IT comes in picture ,through

Its advancement and simplicity Biometrics

Technique become very popular.



GENERIC MODEL OFBIOMETRICS



PHASE OF BIOMETRICS

1.INPUT

2.PROCESS

3.OUTPUT



BIOMETRICS IDENTIFICATION

1. VOICE PRINT

2. FINGER PRINT

3. IRIS PATTERN

4. FACE PRINT 5. HAND GEOMETRY

6. RETINAL SCAN

7. KEYSTROKE DYNAMICS 8. FACIAL RECOGNITION

9. SIGNATURE RECOGNITION



VOICE PRINT

Voice print is recorded by microphones.

Voice print is determined by many different factors: sizeof vocalcactivites (throat, oral, nasal) as well as thecharacteristic of the vocal chords themselves.

Your voice is further modified by the way you speak theway your mouth, lips, teeth, jaw and tongue move.Therefore, the chance of two people have

BACK



FINGER PRINT

Finger print is also called finger scanning. To scan the finger print, a special kind of scanner that can work with

optical rays is used. it fetches the diagram of finger print & delivers it to the computer

where a special programmer measures the distance between thespecial features & that print.

Here, those special features are core, split, island, end &delta. Mostfingerprint data takes up around 250kb BACK



IRIS PATTERN

Iris is located behind the cornea of the eye and front of the lens. Its onlyphysiological purpose is to control the amount of light that enters the eyethrough the pupil, but iss construction from elastic connective tissue gives ita complex, fibrillous pattern.

Finger print technique there are only 90 special features, but in iris patternthere are 266 special features.

BACK



FACE PRINT

It use various features of the face to recognize or verify a user. Use various kind of camera and computer . The computer converted this feature into digital form.

. BACK



HAND GEOMETRY

Most widely used biometrics sys. It use the geometric shape of the hand for authenticating the user’s

identity. Generally two method is used:

1. mechanical.2. Image edge detection.

Hand scanner is used in this method which is shown in fig.

BACK



RETINA SCAN

Retina scan method isbased on the bloodvessel pattern in theretina of eye.

The device used in thismethod is shown in thefig. on this the userposition there headagainst a support and alow power infrared light is

directed against the backof the retina.

BACK



KEYSTROKE DYNAMICS

This method analyzes the way in which auser types at a computer keyboard.

The durations of keystrokes and thelatencies between them are recorded

BAC



FACE RECOGNITON

Facial recognition technique has recentlydeveloped into two areas of study;

1. Facial metrics.2. Eigenfaces.

BACK



SIGNATURE RECOGNITION

It is based on the dynamics of making the signature.i.e. accretion rates, direction, pressure, stroke lengthetc.

The problem is measurement used in the recognitionprocess and repeatability of the signature.

WEB CAM AND MICROPHONE



COMPARISON OF BIOMETRICSTECHNIQUES

Table show the crossover accuracy of different biometrics. crossover accuracy is the ratio of the crossover Frequency

as compared to the whole population of tested data.

Biometrics Crossover Accuracy

Retinal Scan 1:10,000,000+

Iris Scan 1:131,000

Fingerprints 1:500

Hand Geometry 1:500

Signature Dynamics 1:50

Voice Dynamics 1:50



HOW WELL DO BIOMETRICS

WORK?

FALSE ACCEPT RATE

FALSE REJECT RATE

EQUAL ERROR RATE

VALIDITY OF DATA



IS DNA A BIOMETRICS?

DNA differs from standard biometrics in severalways.

DNA is type of biometric in as much as it is theuse of physiological characteristic two verify or

determine identity.



ABOUT BIOMETRICS

Where Biometrics is used?

The new opportunities & FutureTechnologies.

Benefits.



CONCLUSION

We conclude that for biometrics isbetter technique for any security. Thistechnique is improved then unauthorized

person can not access any thing ourassets. It depends on physical behavior.This technique is possible only on the man

identification not its document needed forit.
