Abstract

A wide variety of systems
require reliable personal recognition schemes to either confirm or
determine the
identity of an individual

requesting their servi
ces. The purpose of establishing th
e
identity

is to ensure that only a legitimate user, and not anyone else, accesses the rendered services.
Examples of such applications include secure access to buildings,
airports, computer systems,
cellular phones and ATM machines
.
Biometric recognition,

or simply
biometrics
, refers to the
automatic recognition of individuals based on their physiological and/or behavi
oral characteristics.
Biometrics allows us

to confirm or establish an
individual’s identity based on
who she is
, rather
than by
what she pos
sesse
s

(e.g., an ID card) or
what she know
s

(e.g., a password). Current
biometric systems make use of
identifiers such as
fingerprints, hand geometr
y, iris, face and voice
to establish an

identit
y. B
iometric systems also introduce an aspect of user conveni
enc
e
. For
example, they alleviate the need for a

user to remember

multiple

pa
sswords associated with
different

applications
.
A biometric system that uses a single biometric trait for recognition has to
contend with problems related to non
-
universality of t
he trait, spoof attacks, limited degrees of
freedom, large intra
-
class variability, and noisy data. Some of these problems can be

addressed by
integrating the evidence presented by multiple biometric traits of a user (e.g.,

face and iris
). Such
systems, kn
own as
multimodal biometric systems
, demonstrate substantial improvement in
recognition performance.
In this talk, we will present various applications of biometrics, challenges
associated in designing
fingerprint biometric systems
,
state

of

the

art perfor
mance
, individuality of
biometric identifiers,

and
fusion strategies available to implement a multimodal biometric system.
