3. 1. Biometrics is derived from the conjunction of the Greek words
bios and metrics that mean life and to measure respectively.
2. Biometrics is an accurate method of authentication that uses the
physiological and biological traits of a person to verify and
establish their identity.
3. A Biometrics system is actually a pattern recognition system that
utilizes various patterns like iris patterns, retina patterns and
biological traits like fingerprints, facial geometry, voice
recognition and hand recognition etc….
Functionality of Biometric device:
1. First , it checks whether we are who we claim we are i.e. It sets off
to verify our identity.
2. Second, it tries to find out who we are, i.e. It sets off to establish
an identity.
3. Biometrics goes far from the traditional systems and thus helps in
tightening internet security

4. Authentication is the process of Giving
Permissions
Example:-
Microsoft SQL Server uses permissions to
enforce database security
SQL Server's permissions system recognizes
four types of users: the SA, database owners,
database object owners, and other users of
the database.

7. Fingerprint:
Fingerprint:
It involves the user placing his finger over a glass-
plate, which resides over a high-resolution camera,
which uses optical or electromagnetic means to
take its snapshot. The software analysis your
finger for pattern such as loops, worls and arches
Pros:
a. This technology is neither too expensive
nor does it require extensive user training.
b. It also simple to implement.
c. Finger print system has FAR<0.5%
d. It is oldest known technique that is still
used in criminal records and forensic.
Cons:
1.Any injures of fingers effect more.

8. Hand print:
It compares a 3D image of the users
hand to that present in the system
database. It is somewhat similar to
finger print verification.
Pros:
a. Accuracy is better than
fingerprint.
b. Cheap and easy to deploy.
Cons:
a) Complex in usage.
b) Implementation is expensive.
c) Any damages to hand effect
more.
Applications:
San Francisco International
Airport
Immigration facilities
Day Care Centers

9. Face measurement:
Measuring this is as simple as taking a picture
and analyzing the image from a security video
capture. This technique enables the computer
to use your face as your password and
matching these to an existing database
Pros:
a. Mot continents at public
places.
creams also effect the measurements.
b. Less expensive.
Cons:
Inaccurate is affected by changes in
lighting, age, and movement, glass.
Face

10. Retinal scans:
Retinal scans:
It involves imaging of the blood vessels in the
retina of the eye when infrared light of a certain
frequency and wavelength is incident upon it.this
energy is absorbed by the blood vessels is
different in different individuals.
The retinal iris patterns are unique to individuals
than any biometric yet devised.
The retina is an internal part of the eye
located at the back of the eye and is get of thin
nerve which sense the light coming through a
camera, pupil, eye lenses.
The pattern of blood vessels which
makeup retina are unique to each individual i.e.,
<1.2 inch.

11. Retinal scans:
Pros:
a. Accurate with no false match in 2 million
people.
b. It s sophisticated process.
Cons:
Expensive, difficult to deploy and use.
Focus of light effect measurements.
Applications:
High-end security: military, power
plans

12. DNA Analysis:
It involves in checking the DNA pattern
of a human used when physical characteristics
are unrecognizable. It is used to identify people,
who are died, to find out the relationship like
identifying Childs natural parents.
This is one Biometric that is judicially
accepted. No human have identified DNA
patterns except in twins.
Advantages:
a. DNA samples can be collected from
toothbrush, clothes.
Disadvantages:
DNA testing takes longer time than other
methods.
Twins have same DNA.
Researchers produce same DNA.

14. Typing:
Some systems measure things
you do in addition to the
things you are, you will notice
that your typing has a certain
pattern. Some letters follow
others in quick succession,
while others take longer.
Software called Bio
password is available for less
than $100.It integrates with
Windows 2000.Windows
NT.Login to provide this
authentication without the
need for any additional
software. This measure is a
behavioral characteristic of a
person.

15. Signature:
Some qualities looked into
include acceleration rates, direction,
and pressure and stroke length. Here
mainly concentrate on pressures. This
pressures stored in back end for
future significations.
Disadvantages:
a. The disadvantage with the
technology lies in the randomness or
the consistency with which a user
makes his signature. If pressures are
not tally with stored pressure in the
database
Applications
Access to documents
Execution of contracts
Banking services

16. Voice
It involves in the recognition of
the voice of the individual.
Pros:
It is inexpensive.
It also works through telephone.
Some person mimicry with other person
voices.
Cons:
a. One can mimic the voice of
the individual.
Biometric does not guarantee security.
It simply offers ore convenient and
reliable means of identification and
authentication
Applications:
Call Centers
Law enforcement – house arrest authentication
Electronic commerce
Customer authentication for service calls

18. Identification
It is a process of recognition and involves taking the biometric data and searching for
the match in the database asking it a slow process that it is more prone to errors.
It involves confirming your identity and the biometric
systems have to match your data with only one, single record.
Depending on the technique used, Biometric have varying levels of
accuracy .The system might let you pass in one attempt on Monday and require five on
Tuesday.
The accuracy of any biometric system is measured in terms of FAR and FRR.
FAR (False Acceptance Rates):
Where an imposer is accepted as a match. It is a probability of falsely
accepting a metric as a match.
FRR (False Rejection Rates):
Where a legal match is denied. Where the system sails to recognize an
authentic Bio-signature.
As FRR increases, the FAR goes down and vice versa.
Almost all biometric systems can be adjusted to varying levels of strictness to create a
variation in FAR and FRR. For a system to be successful, both have to be with in
acceptable low limits.

20. Advantages
1. It provide good security mechanism than all other security
methods
2. It never fails in security constraints.
3. In public locations such as banks and airports a large number
of people transit every day including known criminals.
4. Face recognition systems attached to video surveillance
systems are supposed to help catch them.

1st UPI PROJECT IN MAHARASTRA
The worlds first ID project on biometric data is
used to provide unique identification numbers for
India billion plus citizens rolled out on Wednesday
with prime minister Man Mohan Singh & UPS chief
Sonia Gandhi. Handling over the 1st set of 12 digit
no to 10 tribals .
It is a biometric based data including from
fingerprint & iris scan is being used 1st time in the
world to provide cost effective, nationally valid &
verifiable single source of id proof through an
authentication infrastructure.

22. Limitations
1. It needs high memory space in the back
end.
2. Collect data for security is difficult
3. Some times fails the security with right
users
4. Any time data loose in database high
effect for security mechanism.
5. So many equipments are needed for
provide this technology.
6. It highly expensive

23. Conclusions
Security is not just about putting big locks on the front door; it also
involves making sure all the windows are shut.
Each one can be individually fooled, but the comparison makes the
system more secure as a whole.
Biometrics are have its own advantages and disadvantages. It high
expensive but it provide good security.
Money is not important than security. It is more useful for confidential
maters.
