SEMINAR ON FINGER PRINTING
2
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). A fingerprint is an impression of the friction ridges of all or any part of the finger.A friction ridge is a raised portion of the epidermis on the palmar

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 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.
12
METHODS OF CREATING FAKE FINGER:-
DUPLICATION WITH CO-ORPORATION. DUPLICATION WITHOUT CO-ORPORATION.
13
FAKE FINGER DETECTION TECHNIQUES:-
Analysis of static properties of the finger. Analysis of dynamic properties of the finger
14
CONCLUSION:- The biometric use of fingerprint continues to grow as a sensor technology. Fingerprint sensor also ply an important role.
