What is Biometrics ?
|
|
|
|
 Biometrics is known as a
way of using physiological or behavioral characteristics as measuring means. Some
physiological or behavioral characteristics are so unique to each individual
that they can be used to prove the person's identity thru automated
system.

Popular biometric
systems in use today include fingerprint recognition, iris recognition, voice
recognition, and fingerprint recognition systems. Fingerprint recognition is
generally considered the most practical system for its reliability,
non-intrusive interfaces, and cost-effectiveness. Also, there are other
biometric systems are available like retina recognition, vein pattern, face
recognition, signature, and DNA matching systems. These systems are not as
widely used yet for various reasons. Biometric system offers the most accurate
authentication solution and convenience. Biometrics can be integrated into any
application that requires security, access control, and identification or
verification of people. With biometric security, we can dispense with the key,
the password, the PIN code; the access-enabler is you - not something you know,
or something you have in your possession. Remember, biometrically secured
resources are based on who a person is, effectively eliminating risks asociated
with less advanced technologies, while at the same time offering a higher level
of security and convenience.

Fingerprint :
Fingerprint recognition system analyze and compare attributes of the
fingerprints rather than the fingerprints themselves. It analyzes the position
of the end points and junctions of fingerprint ridges, tiny points called
minutiae. Fingerprint is one of the human physiological characteristics that
don't change throughout their lives. Even identical twins have different
fingerprint patterns. The chance of identical twins to have the same fingerprint
is less than one in a billion. Fingerprint recognition system is the most widely
used biometric authentication and the most cost effective. Also, it offers
convenience.

Face
Recognitiont :
Face recognition is identifying or verifying the located face with the already existing data of faces by taking special features of a face on the screen. Face
can be altered by plastic surgery and can change by one's mood or circumstances.
Also, lighting condition, eyeglasses, and facial hair gives variances that it
does not provide secure solution compared to other biometric systems like
fingerprint.

Retina
Patterns :
Both retinas and irises
provide unique bases for biometric identification. Users look into a camera, and
the camera captures high-resolution video images similar to fingerprint images
reading capillaries pattern. The eye is a unique biometric identifier, but the
system's expensive and uncomfortable to use as one has to look into the camera
for 5 sec.

| 
|
Hand
Geometry :
Devices examine the top
and side views of the hand using built-in video cameras and compression
algorithms. Hand geometry is most commonly used at building access control
points. Hand shape can be change.
|
| 
|
Vein
Pattern :
Vein pattern beneath the
skin of hand is detected by using infrared and use the data to identify the
person whom they claim to be. It is easy to use however, the device is a bit
large size and cost-wise it is not attractive.
|
| 
|
Voice
Patterns :
Physiological and
behavioral factors combine to produce speech patterns that can be captured by
speech processing technology. It is inexpensive but is sensitive to background
noise and it can be duplicated. Also, it is not always reliable as voice is
subject to change during bouts of illness, hoarseness, or other common throat
problems.
|
| 
|
DNA
Identification :
DNA identification
is a very powerful means of determining whether two samples of DNA profile may
or may not have come from the same person. It is very expensive and takes long
to go through the whole process to identify. It is widely used for identifying
crime suspects.
|
| 
|
Signature
Dynamics :
Techniques vary, but the
key to signature dynamics is differentiating between parts of the signature that
are habitual and parts that vary with almost every signing. Because of its
usefulness to the financial community, signature dynamics has been an area of
biometric development. The big challenge is gaining enough accuracy to reject
forgers while allowing for the variations of valid users.
