INTRODUCTION:-
On the palmar surface of the hands and feet are raised surfaces called friction ridges .
Fiction ridge are formed during fetal developed.
Fingerprint are unique due to genetic and epigenetic factor(maternal diet,pH,temp,movement of fetus).

HISTORY:- In 14th century Persia, various official government papers had fingerprints
(impressions). 1823: A professor of anatomy at the University of Breslau, published his
thesis discussing 9 fingerprint patterns. 1897: World's first Fingerprint Bureau opens in Calcutta (Kolkata) India. 1902: Dr. Henry P. DeForrest used fingerprinting in the New York Civil
Service. 1906: New York City Police Department Deputy Commissioner Joseph A.
Faurot introduced fingerprinting of criminals to the United States

FINGERPRINT IDENTIFICATION:-FINGERPRINT IDENTIFICATION:-
Fingerprint identification is known as dactyloscopy. Three printer used for identification are: 1.black printer. 2.live scan. 3.larent print. Factors affect friction ridge are pliability of skin,
slippage, the matrix, the surface.

FINGERPRINT CAPTURE:-Two type of fingerprint reader:
1.solid-state fingerprint reader
2.optical fingerprint reader

FINGERPRINT ANALYSIS BASED ON SKIN DISTORTION:
When finger is pressed against the scanner it produces distortion.
Fake finger produces low density distortion.

METHODS OF CREATING FAKE FINGER:-
DUPLICATION WITH CO-ORPORATION.DUPLICATION WITHOUT CO-ORPORATION.

FAKE FINGER DETECTION TECHNIQUES:-
Analysis of static properties of the finger.Analysis of dynamic properties of the finger

CONCLUSION:-
The biometric use of fingerprint continues to grow as a sensor technology.
Fingerprint sensor also ply an important role.
