2. What is biometric ?
• Biometrics is the technology, which uses various individualistic
attributes of a person to verify his or her identity. Various attributes
include fingerprints, geometrical shapes of hands, retina, and iris in
the eyes and so on. Biometric test offers a full-proof and highly secure
method of verification to avoid security breech and unauthorized
access to critical data and places.
Various Characteristics Involved
The characteristics used by biometrics technology are divided into two
groups - physiological and behavioural.
• Physiological characteristics involve face recognition, handprints and
fingerprints, veins in hands, capillary vessels in eyes and so on.
• Behavioural characteristics involve voice modulations, handwriting
and signature style, and keystroke dynamics.

3. Biometric system
• Biometric system is advanced methods to induce
systematization and security at various places like business
organizations, building demanding sophisticated protection
and even the residential areas. Utilizing specific attributes,
these systems can help maintain the much-deserving security
level. Corporate houses are facilitated by these biometric
systems to assess performance of employees and increase
their calibre.

4. Face Recognition Biometric System
• Faces differ on the basis of individuals belonging to different
cultures, races, genders and geographical locations. Biometric
techniques make use of distinctive face nodal points and use
them for authentication process. Face images are captured,
even without informing the person and stored in database for
future identification. Banking, law enforcement and custom
department are few fields utilizing these systems.

5. Fingerprint Analysis Biometric System
• Against the ordinary belief, fingerprints-based biometric
analysis store only specific features, like ridge endings and
bifurcations, of fingers in digital form, instead of capturing
exact finger image. Electronic commerce, law enforcement,
computer and laptop access are few fields, where these
biometrics systems are finding applications. Also, biometric
clocks in offices are based on fingerprint analysis to keep an
eye on employee presence.

6. Voice Recognition Biometric System
• On the basis of throat and mouth shapes and sizes, voice
recognition biometric techniques are becoming popular with
business and other organizations for carrying our biometric
analysis. The voiceprints act as passwords for individuals to
authenticate their entry to various places. Special care is
taken to handle the modifications in voice textures and
interference of other voices from surroundings.

7. Signature Verification Biometric
System
Styles of signing the names differ from an individual to
another. Formation of words, angles of signing and
speed and pressure employed are few factors, which
can form the basis of admirable biometric tools. Banks,
e-commerce and other fields requiring signature
verifications use these systems.

8. Other Biometric Systems in the
Market
• Hand geometry recognition based biometric tools make use of
dimensions, surface area and shape of hands and are used for
residential as well as commercial purposes.
• Algorithms and 2D and 3D imaging facilitate iris recognition
systems to use the structure and patterns of eye vessels as
identification tools.
• Vein structures at the back of hand also form the basis for
biometric systems.
• Keystroke dynamics, involving speed of typing and pressing
various keys, are among other useful biometric techniques.
