SEMINAR
ON
FINGER PRINTING
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).
CLASSIFICATION OF FINGERPRINT:-
ARCH
LOOP
WHORL
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
LFD TECHNOLOGY:-
LFD:
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.
