Abstract—A Biometric System is of one the
essential Pattern Recognition system that are used
for identifying individuals using different Biometric
Traits.The Authentication System design on only
one Biometric modality may not satisfy the
requirement of demanding applications in term of
properties such as Accuracy, Acceptability
&performances. In this paper, we proposed IRIS &
Finger print recognition based on PCA. In
proposed a multi modal recognition system that we
fuses results from both Principal Component
Analysis, Minutia extraction and Weighted LBP
feature extraction on different biometric traits. The
proposed authentication system uses the IRIS and
Fingerprint of a person for recognizing a person.
We will use two different methods for comparing
the performance& accuracy. The classifier viz.,
SVM & ANN are used for matching. It is observed
that proposed algorithm that has best performance
parameters as compared existing algorithms.
Key words: Biometrics, IRIS, Finger Print,
PCA, Minutia, Weighted LBP.
I. INTRODUCTION
In recent year authentication using biometric
system has been considerably improved in
reliability & accuracy. In many of organisation still
biometric system are using for the authentication of
the individuals. Even many of biometric systems
are still facing problems &generally suffers from
many difficulties such as intraclass variability ,
limited Degree of Freedom , noisy input data &
data sets, spoof attack & other related parameters
problems which affect the Performance , Reliability
& Accuracy of
Biometric authentication
system[1].
Mainly biometric system performs the four basic
steps i.e. Acquisition, Feature Extraction, Matching
and Decision making. So the limitations of
unimodal biometric system can be overcome by
multi modal biometric systems. The Biometric
authentication technology certifies recognition of
human on the basis of some unique characteristics
owned by him. IRIS and Finger print recognition
are one of the techniques used for biometric
authentication.

In design of this system we will use two types of
authentication traits of biometric systems i.e. IRIS
and Finger print. IRIS & Finger print images of
person we will use in system for authentication of
them also we will check the reliability and accuracy
of the system, so this system can be helpful in
privacy also.
II. MULTI MODAL BIOMETRIC
Multimodal biometric systems are those that use
more than one physiological or behavioural
characteristic
for
enrolment,
verification
&identification. An overview of Multimodal
Biometrics and have proposed various levels of
fusions, various possible scenarios, the different
kind’s modes of operation, integration methods and
design issues.
Some of the limitations imposed
by unimodal biometric systems can be overcome
by using multiple biometric modalities. Such
systems, known as multimodal biometric systems,
are expected to be safer due to the presence of
multiple independent pieces of proof’s [1].
These systems are also able to meet the stringent
performance requirements imposed by various
applications. Multimodal biometric systems
address the problem of non-universality since
multiple traits ensure sufficient population
coverage. Further, multimodal biometric systems
provide anti-spoofing measures by making it
difficult for an intruder to simultaneously spoof the
multiple biometric traits of a legitimate user [3]. By
asking the user to present a random subset of
biometric traits, the system ensures that a “live”
user is indeed present at the point of data
possession.
Thus, a challenge-response type of authentication
can be facilitated using multimodal biometric
systems. In applications such as boundary entry
&exit, access control, civil identification network
surveillance, multi-modal biometric systems are
looked to as a means of reducing false non-match
and false match rates providing a secondary means

of enlistment, verification, and recognition if
sufficient data cannot be acquired from a given
biometric samples & combating attempts to fool
biometric systems through fraudulent data sources
such as fake fingers [4].
III. PRINCIPLE COMPONENT ANALYSIS
Principal Component Analysis (PCA) is the
generalized technique which uses sophisticated
underlying mathematical principles to transforms a
number of possibly correlated variables into a
smaller number of variables called Principal
Components. [1] The origins of Principal
Component Analysis lie in multivariate data
analysis; however, it has a various range of
applications.
PCA has been called one of the most important
results from applied linear algebra and perhaps its
most common use is as the first step in trying to
analyze huge data sets. Some of the other common
applications include de-noising signals, blind
source separation, and data compression. The PCA
uses a vector space transform to reduce the
dimensionality of large data sets into compressed
data set. Using mathematical principle, the
authenticated data set which may have involved
many variables, can often be explained in just a few
variables (the principal components) [2].It is
therefore often the case that an examination of the
reduced dimension data set will allow the user to
analyze trends, patterns and outliers in the data far
more easily than would have been possible without
performing the principal component analysis [3].
The PCA is mostly used as a tool in exploratory
data analysis and for making predictive models. It
can be done by Eigen value decomposition of a
Data Covariance (or correlation) matrix or singular
value decomposition of a data matrix, usually after
mean centering (and normalizing or using Z-scores)
the data matrix for each attribute. The results of a
Principal Component Analysis are usually
discussed in terms of
component scores,
sometimes called factor scores (the transformed
variable values corresponding to a particular data
point), and loadings (the weight by which each
standardized original variable should be multiplied
to get the component score)[4].

PCA is the simplest of the true eigenvector-based
multivariate analyses. Often this operation can be
thought of as revealing the internal structure of the
data in a way that best explains the variance in the
data.

SUPPORT VECTOR MACHINE (SVM)
In empirical data modeling a process of induction is
used to build up a model of the system, from which
it is hoped to reduce responses of the system that
have yet to be observed. Ultimately the quantity
and amount of the observations govern the
performance of this empirical model. By
observational nature data obtained is limited and
sampled, typically this sampling is non-uniform
and due to the high dimensional nature of the
problem the data will form only a sparse
distribution in the input space. Consequently the
problem is always ill posed in the sense of
Hadamard.Traditional neural network approaches
have suffered difficulties with generalized, produce
models that can overfit the data. These are the step
of the optimization algorithms used for parameter
selection and the statistical measures used to select
the optimize model.
The foundations of Support Vector Machines
(SVM) have been developed by Vapnik in 1995 at
AT & T Bell Laboratory and are gaining popularity
due to many attractive Features and promising
empirical performance. The manipulation embodies
the Structural Risk Minimization (SRM) principle,
which has been shown to be higher to old
Empirical Risk Minimization (ERM) principle
employed by traditional neural networks. SRM will
be minimizes an upper bound on the expected
hazard, as opposed to ERM that minimizes the
error on the training data. This is the difference
which equips SVM with a higher ability to
generalize, which is the target in statistical learning
[1]. SVMs were developed to solve the
classification problem, but recently they have been
extending to the domain of regression problems.
The term SVM is typically used to describe
classification with support vector methods and
support vector regression is used to describe
http://www.ijettjournal.org
Page 79

regression with support vector methods. In this
paper the term SVM will refer to both classification
and regression methods and the terms Support
Vector Classification (SVC) and Support Vector
Regression (SVR) will be used for specification.
This part will continue with a complete
introduction to the structural risk. Minimization
principle [1]. The SVM is introduced in the setting
of classification, being both historical and more
usable. This leads onto mapping the input into a
higher dimensional feature space by a require
choice of kernel function. The report then considers
to the problem of regression. SVM has successful
application in Bioinformatics, Text & Image
Recognition.
ARTIFICIAL NEURAL NETWORK (ANN)
Artificial Neural Networks (ANN) are non-linear
mapping structures based on the function of the
human brain. The human brain is powerful tools
for modeling especially when the underlying data
relationship is unknown. ANN can identify and
learn related patterns between input data sets and
corresponding destination values. After training,
ANNs can be used to predict the outcome of new
independent input data. ANNs imitate the learning
process of the human brain and can process
problems involving non-linear and complex data
even if the data are imprecise and noisy. Thus
they are naturally suited for the modelling of
agricultural data which are known to b e
difficult and often non-linear. ANNs has more
capacity in predictive modelling i.e., all the
characters describing the unknown situation can
be presented to the trained ANNs, and then
guess on agricultural systems is guaranteed.
An ANN is a computational structure that is
inspired b y observed process in natural networks
of biological neurons in the brain. It consists of
easy computational units called neurons, which
are highly connected with each other. ANNs have
become focus the much attention, largely because of
their large range of applicability and the ease with
which they can treat difficult problems. ANNs are
parallel computational models comprised of densely
interconnected adaptive execution units. These
networks are fine grained parallel implementations
of nonlinear static or public systems. This is
important feature of these networks is their
adaptive nature, where “learning by example”
replaces “programming” in solving problems.
This feature are used makes such computational
models very appealing in application domains
where one has little or incomplete understanding of
the problem to be solved but where training data
is already available.
the area of classification and prediction, where
regression model and other related mathematical
techniques have traditionally been employed.
The most widely used learning algorithm in an
ANN is the Back propagation algorithm. There
are various types of ANNs like Multilayered
Perception, Radial Basis Function and Kohonen
networks. These networks are “neural” in the
sense that they may have been inspired by
neuroscience but not necessarily because they
are faithful models of biological neural or
cognitive phenomena. In fact most number of
the network are more closely related to
traditional mathematical and statistical models
such as non-parametric pattern classifiers,
clustering algorithms, nonlinear filters, and
statistical regression models than they are to
neurobiology models.
ANNs have been used for a wide variety of
applications where statistical methods are
conventionally employed. The problems which
were normally solved through classical statistical
methods, such as discriminant analysis, logistic
regression, Bayes analysis, multiple regression,
and ARIMA time-series models are being
tackled by ANN. It is therefore, time to recognize
ANN as a powerful tool for data analysis.
IV. METHODOLGY
In this approach of IRIS & Finger Print
Recognition using Principle Component Analysis
even though various classifiers are specified
already but less accuracy are matched in available
Data Set & Real Image. So this is the challenging
part when we think about designing this application
[1].
Our Solution is as follows:
Firstly collect the data base of IRIS &
Finger print of Individuals separately.
Take a Real Appearance of IRIS & Finger
of Individual.
Using Algorithms associated Classifiers;
we will compare both the snap at
Extraction Point by different classifiers.
So formulate the Result of Extraction
point of snap, after that check the
Acceptance Ratio& Rejection Ratio
distinctly.
So from the Point of Exemption, we can
analysis accuracy level of Snap.
ANNs are now being increasingly recognized in

V. PROPOSED IMPLEMENTATION
Hardware Platform: We will useFutronics FS
80 Biometric Finger Print Module & IRIS
Scanner Module for the taking the Real snap
of
Finger
&
IRIS
Templates
respectively.Futronics FS 80 module is
Electronic device used to capture a digital
image of the fingerprint pattern.It is very
compatible
&excellent
communications
reliability with power supply in a wide range
of secureapplications. Iris Scanner module
performs recognition detection of a person's
identity by mathematical analysis of the
random patterns that are visible within the iris
of an eye from some distance.
It combines computer vision, pattern
recognition, statistical inference and optics it is
generally conceded that IRIS recognition is the
most accurate. Iris cameras, in general, take a
digital photo of the iris pattern and recreating
an encrypted digital template of that pattern.
That encrypted templates cannot be
reproduced in any sort of visual image.
IRIS recognition therefore affords the highest
level defence against identifying theft, the
most immediately growing crime. Today's
commercial IRIS Scanner use infrared light to
illuminate the iris without causing harm or
discomfort to the eye. So along with this both
hardware we will use the software that is
MATLAB version 8 for the implementation of
system.
So in the implementation of system, we will take
the snap of IRIS & FINGER print, and then it will
passes through the isolated processing respectively.
After processing of data it will send through PCA
algorithms along with the classifier. So after that
feature extraction & fusion matching of real snap
with enrolled data set will take place. Then at the
end we will get the recognised result from the
system [1].
VI. CONCLUSION
This is first kind of implementation on IRIS &
FINGER print recognition using PCA for multi
modal biometric system with this specialized
hardware’s & software, but such an implementation
is very much costly [1]. So Same thing we can
implement using low cost only with the real
appearance of Finger print with its module &
present data set of IRIS snap without its module.
The cost of IRIS module is too costly; if we don’t
required real data set of IRIS then it is possible.
