Outline:

y What is biometrics ?

y What is the need for it ?

y Requirements of a good biometric systemy My opinion of this technology

y Questions ???


3/20

Biometrics:

Biometrics is an advanced technology for high grade

protection and authentication. The term Bio relates it

to the biological studies and metrics relates it to themeasuring something.

Basically the main need for the use of biometrics is to

enhance security and Security


4/20

TWO MAIN USES:

1) IDENTFICATION

-figure out Who is X?

-accomplished by system performing a one-to-many search

2) VERIFICATION

-answer the question Is this X?

-accomplished by the system performing aone-to-one search


5/20

Methods of Verification:

1) Physiological verification:

Psychological Verification involves in the verification of

the organs of the human being, which will have uniqueidentification and does not match with others.

2) Behavioral Verification:

This involves in behavioral factors done by the

individual.


6/20

Physiological Verification:

y There are five types of verifications. These are:

y 1. Fingerprint.

y 2. Handprint.

y 3. Face measurement.

y 4. Retinal scans.

y 5. DNA analysis


7/20

Finger print detection: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


8/20

Advantages :

y Advantages:

y This technology is neither too expensive nor does it

require extensive user training.y It also simple to implement.

y Finger print system has high efficiency and reliability.

y It is oldest known technique that is still used in criminal

records and forensic.


9/20

Hand print detection :In this method instead of scanning the finger prints,

entire hand is scanned and it is matched with the

templates to get a match and the procedure it followsis same as in previous case. It also sometimes

compares a 3D image of the users hand to that

present in the system database. Anyhow it is

somewhat similar to finger print verification


10/20

Face measurement:

This is as simple as taking a picture and analyzing the

image from a security video capture. This technique

enables the computer to use our faces as a passwordand matching these to an existing database. This

feature is being used nowadays in many fields

including the forensic departments for the

identification of criminals and also used in highsecurity areas.


11/20

Retinal scans :

y 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 bythe blood vessels is different in different individuals.

y The retinal iris patterns are unique to individuals than any

biometric yet devised.


12/20

Advantages of retinal scan systems :

y Biggest advantage is its reliability& the process gets

over in just a fraction of two seconds.

y Iris being well protected inside the eye & doesnt getdamaged easily. But if a person is up to some manual

labor, the finger prints get ruptured & it becomes

difficult to take them. So, iris can be best used.

y Verification of finger prints is very difficult & time

taking because they are too complex. But in case of

iris recognition more than 5000 templates can be

verified just in a minute


13/20

DNA analysis

y 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 therelationship like identifying Childs natural parents.

y No human have identified DNA patterns except in twins.

In other cases the DNA strands doesnt have same set of

sequence of molecules in any individual providing us ahigh grade factor of consideration for biometric security

purposes.


14/20

Behavioral verification:

y This involves in behavioral factors done by the individual.

There are 3 types of behavioral verifications,

y1. Typing

y 2. Signature

y 3. Voice


15/20

Typing:Some systems measure things you do in addition to thethings you are, it is a fact that the typing has a certain

pattern for every individual and various from oneperson to another and this can also be used forpurpose of knowing a persons identity. Some lettersfollow others in quick succession, while others takelonger.


16/20

Signature :

y The way in which people write their signature is recorded

along with the precision and speed of the writing and

this data is used for the verification purposey This one is the most earliest methods of biometric

methods.


17/20

Voice recognition:

y It involves in the recognition of the voice of the

individual.

yThe obtained voice of the individual is checked for thebest match available in its storage to identify the person

and his extent of accessibility to the resources


18/20

Future of biometrics:

y With the development of advanced sciences and itsfollowing streams including electronics, nano technologyand biomedical fields the field of biometrics has a greatrange of scope in the near future. Even nowadays thebiometric devices are brought to existence as a major dayto day used device and with the development of it in the

future it will be of great importance in the securitysectors.

y One such evidence for it is the use of biometric devices inpublic areas and in the usage of devices and networks


19/20

My idea of biometric technology:

According to my view ,biometric technology is one of

the most promising technologies for the security of the

numerous databases and resources , as it provides bettersecurity against the unauthorised access of resources by

people and it helps to keep the data encapsulated from

the access of wrong people simultaneously meeting

benefit of low cost and best security.


20/20

Conclusion: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 thecomparison makes the system more secure as a whole.

Biometrics has its own advantages and disadvantages. It

high expensive but it provides good security. Money is not

important than security. It is more useful for confidential

maters.
