What is a biometrics , types of biometrics , biometric system and advantages of biometrics.
The question what is biometrics , types of biometrics , uses and biometrics accuracy , all we discuss
here so first ....
The word Biometric came from bios and metric (the Greek words). Where bios represent life and
metric represent measurements. Biometrics science deals with measuring and analysis of behavioral
and physical characteristics of an individual in a fast , easier and reliable way. It help the individual to
be digitally identify and authenticate him to access his devices system or data.
Types of Biometrics -
1) Behavioral Biometrics
2) Physical Biometrics (physiological)
Behavioral Biometrics - They related to the behavior of a individual and are very unique to a person
. Ex are walking gait , recognition of speak , typing pattern , movement of lips , signature , skin
reflectance. They are not so old in biometrics and usually used with another biometrics as of their
low reliability. The enchantment is still going on.

Physical Biometrics - They measure the physical (some inherent ) characteristics of an individual i.e
related to the shape of the body. Ex are recognition of face , DNA of a person , fingerprints of an
individual , Iris & retina, hand shape , vein pattern. Physical Biometrics are stable in an individual
life.
How Biometrics system used or work -
Its purposely used for individual identification . The process is simple we get the individual
characteristics and compare it with our storage data to found resemblance.
characteristics and compare it with our storage data to found resemblance.
Biometrics device contains -
1) A scanning device or reader to record the individual characteristics.
2) A software which help to convert scanning data in to digital format and resemble the scanned data
with our stored data.
3) For storing and comparing a database.
Characteristics of Biometrics -
1) Permanent - Not disappear with time.
2) Unique - Differ from person to person. Unique to every individual.
3) Universal - Both physical and behavioral biometrics found in all of us.
4) Measurable - All are easily accessible and collected.
5) Correctness - Identify the individual accurately.
6) Convenience - Easily and conveniently imitated or obtained.
Uses of Biometrics -
1) Biometrics used in public security and in law enforcement for criminal identification. AFIS
system (Automated Fingerprint Identification System) is used by the police departments and other
law enforcement agencies for criminal identification. When we add other biometrics (face
recognition , iris etc) with AFIS system then its known as ABIS (Automated Biometric Identification
Systems) .

2) Biometrics used in identification of civil person . In INDIA , the largest Biometrics system named
"Aadhaar" is working . Its contains the biometrics data of fingerprints , iris scan of two eyes and
photograph of individual. A twelve digit identification number is given to Indian citizens. So
biometric is used for public subsidy schemes , voter identification , benefits schemes for
unemployment etc. It helps in population registration.

3) Biometrics is used in Healthcare system by developed countries. They issued the health insurance
card to the individual which is used in hospitals , clinics etc.The health insurance card consist the
fingerprints and other Biometrics.
4) Biometrics help in access control over computers system and in mobile phones (IT related items)
which are having biometrics authentication system. Its help to prevent unauthorized access in to the
biometrics system.

5) Biometrics help the telecom companies , Governments and private banks to know there customers
in a faster an efficient way. Companies know there customers through there KYC (know your
customers) check. Its help to prevent financial crime.

6) Biometrics helping the developed countries in (and will help the developing countries in)
travelling , migration and border control. The biometrics document e-passport helps in travelling
and easily access to airports and in airlines. Biometrics also help in border control as it speed up the
crossing between two borders and control the flow of migrants.

Advantage of biometrics
1) It is very easy to use and very convenient.
2) The biometrics (some) characteristics of an individual change very little in life. DNA ,
fingerprints etc did not changed.
3)They are not transferred to others.
4) They take very less storage.
5) Nobody can steal them. passwords could be hacked.
Disadvantage of biometrics
1) Biometrics system cost and the cost of running is costlier.
2) Didn't identify an individual if the biometrics data not captured in the system (for any reason).
3) Biometrics characteristics can't be steal but biometrics data can be. The security of database is
must as you can change your password if it exposed but don't change your fingerprints etc.
4) If a person wearing mask or anything like glasses then he can not be identify in facial recognition
system and if an individual is sick the voice changed.
