PRESENTATION ON BIOMETRICS
is the identification or verification of human
identity through the measurement of
repeatable of physiological and behavioral
CATEGORIES OF BIOMETRICS
can be stored into two classes
Examples face-recognisation, fingerprints
Examples signature and voice etc.
MODES IN WORKING
A sample of biometric trait is captured,
processed by computer, and stored for later
In this mode biometric system authenticates
a person’s claimed identity from their
previously enrolled pattern.
Principle: Analysis of unique shape, pattern
and positioning of facial features
and low-cost, but less accurate and
sometimes lengthly enrollment.
iris pattern are obtained through a video
based image acquisition system.
The movement of the pen during the signing
process rather than the static image of the
signature. Many aspects of the signature in
the motion can be studied, such as pen
pressure, the sound the pen makes.
ADVANTAGES OF BIOMETRICS
Biometric identification can provide extremely
accurate, secured access to information ,
fingerprints, retinal, and iris scans produce
absolutely unique data sets when done properly.
Current methods like passwords verification have
many problems( people write them down they forget
them, they make up easy to hack passwords)
Automated biometric identification can be done very
rapidly and uniformly, with a minimum of training.
Your identity can be verified without resort to
document that may be stolen, lost or altered
DISADVANTAGES OF BIOMETRICS
The finger prints of those who are working in checimal
industries are often affected . Therefore these companies
shouldn’t use finger print mode of authentication.
It is found that with age, the voice of a person differs. Also
when the person has flue or throat infection the voice
changes or if there are too much noise in the environment
this method may not authenticate correctly Therefore this
method is not workable all the time.
For people affected with diabetes, the eyes get affected
resulting in differences.
Biometric is an expensive security solution.
personnel look for biometric data
that doesnot change over the course of your
FUTURE OF BIOMETRICS
The future of biometrics holds great promise
for law enforcement applications, as well for
private industry uses.
Biometrics' future will include e-commerce
applications for extra security on the
