ABSTRACT: Fingerprint recognition is the reliable and oldest biometrics used for personal identification. Many sensors were
developed for fingerprint recognition systems in which the user’s finger print is placed on a sensor. Due to this contact the
input fingerprint from the same finger can be different and there can be fingerprint issues which can lead to forgery and
hygienic problem. For this reason touchless fingerprint recognition has been developed in which the fingerprint is acquired
using a high resolution webcam. The acquired images are subjected to pre-processing steps and the region of interest is
extracted. Minutia features are extracted from the fingerprint image and matching is based on the number of minutia
pairings among two fingerprints to be matched. The project is coded in Matlab.
KEYWORDS: Biometric, Fingerprint, Minutia, Crossing Number, FAR, FRR.
1 INTRODUCTION
Human beings possess psychological and behavioural characteristics. The measure of these characteristics is called
Biometrics. Biometrics is used for personal identification and verification. Voice, lip movements, hand geometry, face, odour,
gait, iris, retina, fingerprint are the most commonly used authentication methods. Biometrics is actively growing area of
research. The driving force of the progress in this field is, above all, the growing role of the Internet and electronic transfers in
modern society. The biometrics has a significant advantage over traditional authentication techniques namely passwords, PIN
numbers, smartcards etc. due to the fact that biometric characteristics of the individual are not easily transferable, are
unique of every person, and cannot be lost, stolen or broken. The choice of Biometrics depends on accuracy, user acceptance,
cost and implementation time and level of security required.
Of all the biometric based recognition systems, fingerprint based recognition systems is one of the oldest and most
reliable biometric used for personal identification. A fingerprint is the pattern of friction ridges on a human finger, which
provides increased friction for gripping. A fingerprint consists of ridges and valleys. Fingerprints are not distinguished by
ridges and furrows but by minutia which are abnormal points on the ridges. Among the variety type of minutia, two are
mostly significant and in heavy usage: one is called termination, which is the immediate ending of a ridge; the other is called
bifurcation, which is the point on the ridge from which two branches derive. The characteristics of fingerprint are:
i. A fingerprint is an individual characteristic: No two persons, even identical twins does not have similar fingerprint
pattern. The probability of two fingers being same is 1 in 1.9×10
15
[1, 2, and 3].
ii. Fingerprints remains unchanged during a lifetime. Only a very deep cut would result in changes in a fingerprint.
iii. Fingerprint has general ridge patterns that permit them to be classified.
