seminar on finger printing

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:-

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.
