Security Concerns

ENVIRONMENTAL CONCERNS


In conventional ATMs


PIN is needed


PIN comes in an envelope which contains
2 sheets of paper and between this
sheets secret code is marked


RBI report says


25000 new accounts
are opened daily


On yearly basis, a lot of paper is required


leads to cutting of trees

SECURITY CONCERNS


Anybody holding the card with PIN number
known can operate


No need to be the original owner of the
card


In Bio metric only the original card holder
can operate

BIO METRIC ATMs


Biometrics refers to the automatic
identification of a person based on his
physiological/behavioral characteristics.


Various types of biometric systems are
being used for real time identification;most
popular are based on face recognition and
finger print matching.

WHY USE IT?


Traditional methods involving passwords
and PIN numbers


Biometrics highest level of security

VARIOUS BIOMETRIC SYSTEMS

1.
HAND


The three dimensional shape of a
person’s hand has several advantages
as an identification device. Scanning a
hand and producing a result takes
1.2seconds.It requires little space for
data storage about 9 bytes which can fit
easily magnetic strip credit cards.

2.
FINGER PRINT


Most of the work in biometrics
identification has gone into the finger
print for general security and access
control application fingerprints are
gaining popularity.

MULTIBIOMETRICS

1.
INTEGRATING FACES AND FINGER PRINTS
FOR PERSONAL IDENTIFICATION


An automatic personal identification
system based on fingerprints or faces is often
not able to meet the system performance
requirements.



MULTIBIOMETRICS

2.
A MULTIMODEL BIOMETRIC SYSTEM
USING FINGERPRINT, FACE AND SPEECH


This system takes the advantage of the
capabilities of each individual biometric. It can
be used to overcome some of the limitations of
a single biometrics.

CONCLUSION


A range of biometric systems are in
developments or on the market because no one
system meets all needs. The trade off in
developing these systems involve component
cost, reliability, discomfort in using a device, the
amount of data needed and other factors. But

the application of advanced digital
techniques has made the job possible.
Further experiments are going all over the
world.
