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.

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

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.

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.

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.

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.

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

FACE RECOGNITON
Facial recognition technique has recentlydeveloped into two areas of study;
1. Facial metrics.2. Eigenfaces.

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.

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

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.

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.
