Introduction

The term "biometrics" is derived from

the Greek words bio (life) and metric

(to measure).The biometric provides

most secure level of authorization.

5/25

Physiological

Physiological are related to the shape of the

body. Examples include fingerprint, face

recognition, DNA, hand and palm geometry,iris recognition, which has largely replaced

retina.


6/25

Behavioral

Behavioral are related to the behavior of a

person. Examples include, but are not limited

to typing rhythmand voice.

Uses Of Biometrics

Identification

Verification


8/25

Identification

Identification is determining who a person is.

It involves taking the measured characteristic

and trying to find a match in a database

containing records of people and that

characteristic. This method can require a large

amount of processing power, some time, if the

database is very large. It is often used indetermining the identity of a suspect from

crime scene information


9/25

Verification

Verification is determining if a person is who

they say they are. It involves taking the

measured characteristic and comparing it to the

previously recorded data for that person. This

method requires less processing power and

time, and is often used for accessing places or

information.


10/25

How It Works

Biometric devices consist of a reader or

scanning device, software that converts the

gathered information into digital form, and a

database that stores the biometric data forcomparison with previous records. When

converting the biometric input, the software

identifies specific points of data as matchpoints. The match points are processed using

an algorithm into a value that can be compared

with biometric data in the database

13/25

Finger Print

An extremely useful

biometrics

technology sincefingerprints have long

been recognized as a

primary and accurateidentification method.


14/25

Facial recognition

Biometric face recognition

works by using a computer to

analyze a subject's facial

structure. Face recognition

software takes a number of

points and measurements,

including the distances between

key characteristics such aseyes, nose and mouth, angles of

key features such as the jaw

and forehead, and lengths of

various portions of the face.


15/25

Hand geometry

Hand geometry systems are

commonly available in two

main forms. Full hand

geometry systems take an

image of the entire hand forcomparison while Two

Finger readers only image

two fingers of the hand.

Hand recognitiontechnology is currently one

of the most deployed

biometrics disciplines world

wide


16/25

Iris Scan

Analysis of the iris

of the eye, which is

the colored ring of

tissue that surrounds

the pupil of the eye.


17/25

Retina Scan

The blood vessels at theback of the eye have a

unique pattern, from eye

to eye and person to

person.

No two retinas are the

same, even in identicaltwins.


18/25

Vascular patterns

Uses an infrared

camera to measure

the veins on the wrist

and back of the hand.


19/25

DNA

DNA has been called

the ultimateidentifier

Identify informationfrom every cell in the

body in a digital form.

20/25

Speech Recognition

Speech recognitionconverts spoken

words to text. It is

based on two speechinput:

1.Text dependent

2.Text independent


21/25

Signature

Many aspects of the

signature in motion

can be studied, such

as pen pressure, the

sound the pen makes


22/25

Keystroke

The rhythms with which

one types at a keyboard

are sufficiently distinctive

to form the basis of thebiometric technology

known as keystroke

dynamics


23/25

Voice Recognition

voices are unique to each person (includingtwins), and cannot be exactly replicated by

using this recognition technique.


24/25

Features

Reduce password administration costs.

Increase security

Eliminate problems caused by lost IDs orforgotten passwords
