History About Biometric TechnologyThe ancient Egyptians and the Chinese played a
large role in biometrics history.Biometrics in practice was a form of finger printing
being used in china in the 14th century.Bertillon developed a technique of multiple body
measurements .A system called “Indentimat” which measured
shape of the hand and length of fingers was introduced in 1970s.
What is Biometrics ? Biometrics the science with technology to measure and
analyze biological data.
Meaning of Biometrics comes from the Greeks. Biometry = bio(life) + metry(to measure).
Biometrics refers to automated methods or technologies that measure and analyze human body characteristics like DNA, fingerprints, eye retinas and irises, voice patterns, facial patterns and hand measurements for authentication purposes.

Face Recognition Principle: analysis of the unique
shape, pattern and positioning of facial features.
A automated software for identifying or verifying a person from a digital image or a video frame from a video source. Typically used in security systems.
Uses an image or series of images either from a camera or photograph to recognize a person.
Highly complex technology.
How Face Recognition works?
Iris Recognition The iris of each eye of each
person is absolutely unique.
The false acceptance rate for iris recognition systems is 1 in 1.2 million.
Iris pattern is not changed over years or by glasses, contact lens
Problems to Iris ScanningScanning difficult from a larger distance. It uses INFRARED light which may cause damage to our
eyes.An eye photograph can also be used to gaining the access.
Retina scan It analyzing the layer of blood
vessels situated at the back of the eye.
The machine takes around ten seconds to shine a “low intensity coherent light source” onto the retina to illuminate the blood vessels.
Once the machine has a copy of the scan, it compares the picture to all the different scans of databases, looks for a match, and identifies the individual.
Retina scan machines are fairly expensive.
Fingerprint Recognition A fingerprint in its narrow sense is
an impression left by the friction ridges of a human finger.
Biometrics refers to that measure and analyze human body characteristics such as fingerprints recognition.
Fingerprint recognition is possible using the fingerprint scanner.
A fingerprint scanner has two basic jobs.
It needs to get an image of your finger.

How Finger-Print Works?
Problem to Finger Print System
Finger prints can be easily copied.
Wrong result is shown if the finger is not placed properly.
If the software is not sufficiently god negative result is shown.
Advantages of fingerprint Recognition
Oldest form of Biometrics Highly Reliable Uses easily features of fingers High Security access Reduce cost Instance Report
Voice Recognition
It’s a habitual speaking recognition.Voice recognition systems analyze differences
such as in pitch, and tone.This biometric is also sensitive to environmental
conditions such as background noise.Template size can vary significantly according to
the length of the pass phrase.
Signature Recognition
Static Dynamic
In this mode, users write their signature on paper, digitize it through an optical scanner or a camera, and the biometric system recognizes the signature by analyzing its shape. It is also known as “off-line”.
In this mode, users write their signature in a digitizing tablet, which acquires the signature in real time. Dynamic recognition is also known as “on-line”.
One of behavioral biometric: Signature recognition
Operated in two different mode:
Signature Recognition Application
Criminal identification Prison security ATM and other Financial Transactions PC/LAN Login Database access Border crossing controls
Advantages of Biometrics
Biometrics are generally used for authentication. It provides higher security .e.g. Iris
recognition . Voice Recognition works well over the
telephone User friendly e.g. Hand geometry recognition, finger print recognition
Disadvantages of BiometricsRetina recognition requires close physical contact
of the scanning device, may not be generally accepted by public
This technology is little Costly.Voice recognition requires large amount of
computer storage, people's voices can change, background noises can interfere.
Biometrics features may change over time.Signature recognition has poor long-term
reliability, accuracy difficult to ensure.
A biometric system can operate in two modes
Identification:• A one to many comparison of the captured biometric against a
biometric database in attempt to identify an unknown individual.
Verification:• A one to one comparison of a captured biometric with a stored
template to verify that the individual is who he claims to be. • Verification is faster and performs better.• In a verification, the user must first enter his or her identity to
the biometric system. User ID's can be forgotten and cards can be lost, making access impossible.

Conclusion
Not to remember passwords.
User friendliness.
A new way to interact with devices.
