of analysing bulk data for a shared data storage system. In
this technique the main aim is to preserve the data
sensitivity and data privacy with accurate analysis of
combined data. In this paper the privacy preserving data
mining is the key domain of investigation and a new system
proposal. In this context a number of different recently
developed PPDM based data mining techniques. In addition
of that for designing an accurate and effective PPDM model
a new data mining model is also suggested in this work.

proposed work.
Key Words: (PPDM, centralized data mining, privacy and
security, multi party data mining, decision mining.
1. INTRODUCTION
The main aim of the data mining and its techniques is to
analyses the data and obtain the application oriented
patterns from data. Therefore in a number of applications
it is accepted. In this context the main component of
pattern recovery and data mining is “Data”. The data
mining algorithms are applied on the data and recover the
patterns which can be used for decisionmaking, prediction
and other necessary task. But sometimes the complete
information is not available on single place or single party.
Therefore decision making capability is affected due to
availability of fewer amounts of data attributes. Therefore
it is required to combine multiple parties of data for
finding effective decision making ability [1].
In this context, not all parties are agreed to combine their
data openly due to security and privacy of the end data
owners. Therefore in order to process and mine the data
more effectively and with the needs ofsecurityandprivacy
preservation some new kinds of systems are required. In
order to fulfill the requirement of security and privacy
during processing the multiparty data the PPDM (privacy
preserving data mining) is the suitable technique of
information processing. Therefore in this presented work
the main aim is to study and explore the techniques of
PPDM and its applications in real world domain. In
addition of that a new privacy preserving association rule
mining technique is also proposed for design and
implementation [2].
This section provides the basic overview of the proposed
work involved in this survey paper and in next section
some key terms and definitions are included for study and
system understanding.
2. BACKGROUND
This section provides the understanding of the different
key terms which are used for explaining the proposed
concept of privacy preserving association rule mining.
PPDM: PPDM (privacy preserving data mining) is the sub-
domain of data mining. In this environment the data
mining techniques and algorithms are employed on data
with the key aim of privacy and security of end user data.
Therefore in order to implement such technique
cryptographictechniques,noisebasedtechniques,blocking
based techniques are frequently used for preserving
privacy and sensitivity of end data owner’s privacy and
security [3].
Vertically partitioned data: when the data is distributed
among multiple parties with non-similar kind of attributes
and similar class labels this kind of data partitions of
database is termed as vertically partitioned data [4].
Horizontal partitioneddata: inthis environmentthedata
is distributed among multiple parties with the similar
number of attributes and class labels but the amount of
data instances for all the parties are different such kind of
data arrangement is known as the horizontal partitioned
data [4].
Association rule mining: association rule mining
technique is a data mining technique where the
relationship among the data attributes are established on
the basis of their frequencies and combination of different
attribute values. Such kinds of techniques are used for
prediction and decisionrulebuilding.Thereareaprioriand
FP-tree algorithmsareavailableforassociationrulemining
[5].
Multiparty data: in some complex cases the less attribute
based information can affect the final decision making
process for a business domain. Therefore multiple data
owners are agreed to combine and process their data in a
common place for mining the common decisions from
entire collected data. Thiskindofdata mining environment
is termed as the multiparty data mining environment [6].](https://image.slidesharecdn.com/irjet-v6i3203-190816062040/85/IRJET-A-Study-of-Privacy-Preserving-Data-Mining-and-Techniques-1-320.jpg)

Sensitive data: different parties of data ownershavingthe
different set of attributes. These attributes may contain
some confidential and private data of end user. The
discloser of such kind of data can impact of someone’s
social or financial privacy is known as the sensitive part of
data for example creditcardinformation,dateof birth,PAN
card number and other private information [7].
Decision mining: the data or information is processed
with the aim to generate decisions by evaluation of
available attributes can be defined as the decision mining
or rule mining. In this context the decision trees and
association rule mining techniques are played essential
role [8].
3. LITERATURE SURVEY
This section includes the different recently placed
contributions and efforts for improving the existing
technique of PPDM (privacy preserving data mining).
Association rule mining andfrequentitemsetminingistwo
popular and widely studied data analysis techniques for a
range of applications. In this paper, Lichun Li et al [9]
focus on privacy preserving mining on vertically
partitioned databases.Insucha scenario,data ownerswish
to learn the association rules or frequent itemsets from a
collective dataset, and disclose as little information about
their (sensitive) raw data as possible to other data owners
and third parties. To ensure data privacy, authors design
an efficient homomorphic encryption scheme anda secure
comparison scheme. Then propose a cloud-aided frequent
itemset mining solution, which is used to build an
association rule mining solution. The solutions are
designed for outsourceddatabasesthatallowmultipledata
owners to efficiently share their data securely without
compromising on data privacy. The solutions leak less
information about the raw data than most existing
solutions. In comparison to the only known solution
achieving a similar privacy level asourproposedsolutions,
the performance of our proposed solutions is 3 to 5 orders
of magnitude higher. Based on experiment findings using
different parameters and datasets, we demonstrate that
the run time in each of our solutions is only one order
higher than that in the best non-privacy-preserving data
mining algorithms. Since both data and computing work
are outsourced to the cloud servers, the resource
consumption at the data owner end is very low.
The collection and analysis of data are continuously
growing due to the pervasiveness of computing devices.
The analysis of such information is fostering businesses
and contributing beneficially to the society in many
different fields. However, this storage and flow of possibly
sensitive data poses serious privacy concerns. Methods
that allow the knowledge extraction from data, while
preserving privacy, are known as privacy-preserving data
mining (PPDM) techniques. Ricardo Mendes et al [10]
surveys the most relevant PPDM techniques from the
literature and the metrics usedtoevaluatesuchtechniques
and presents typical applications of PPDM methods in
relevant fields. Furthermore, the current challenges and
open issues in PPDM are discussed.
Paillier cryptosystem is extensively utilized as a
homomorphic encryption scheme to ensure privacy
requirements in many privacy-preserving data mining
schemes. However, overall performanceoftheapplications
employing Paillier cryptosystem intrinsically degrades
because of modular multiplications and exponentiation
operations performed by the cryptosystem. In this study,
Ismail San et al [11] investigate how to tackle with such
performance degradation becauseofPailliercryptosystem.
They first exploit parallelism among the operations in the
cryptosystem and interleaving among independent
operations. Then, authors develop hardware realizationof
our scheme using field-programmable gate arrays. As a
case study, they evaluate crypto processor for a well-
known privacy-preserving set intersection protocol.
Authors demonstrate how the proposed crypto processor
responds promising performance for hard real-time
privacy-preserving data mining applications.
Clinical Decision Support System (CDSS), withvariousdata
mining techniques being applied to assist physicians in
diagnosing patient disease with similar symptoms, has
received a great attention recently. The advantages of
clinical decision support system include not only
improving diagnosis accuracy but also reducing diagnosis
time. In this paper, Ms. Meenal V. Deshmukh et al [12]
have given the CDSS with some advance technologies like
Support Vector Machine (SVM) classifier has offeredmany
advantages over the traditional healthcare systems and
opens a new way for clinicianstopredictpatient’sdiseases.
As healthcare is the field in which Security of data related
to patient diseases are needs to be more secure, for that in
this paper, author has use RSA and Homomorphic
encryption technique that properly meets the security
Goals. Specifically, with large amounts of clinical data
generated every day, support vector machine (SVM)
classification can be utilized to excavate valuable
information to improve clinical decision support system.
Although clinical decision support system is quite
promising, the flourish of the system still faces many
challenges including information security and privacy
concerns. In this they will use Homomorphic encryption
technique to preserve the patient’s privacy on the cloud.
The patient’s data can be compromised over the cloud. To
overcome this scenario homomorphic encryption
technique helps. The processing is done on the encrypted
data; hence there is no chance of compromising privacy of
patient’s data.
With the popularity of smart handheld devices and the
emergence of cloud computing, users and companies can
save various data, which may contain private data, to the](https://image.slidesharecdn.com/irjet-v6i3203-190816062040/85/IRJET-A-Study-of-Privacy-Preserving-Data-Mining-and-Techniques-2-320.jpg)

cloud. Topics relating to data security have therefore
received much attention. Chen‑Yi Lin et al [13] study
focuses on data stream environments andusestheconcept
of a sliding window to design a reversible privacy-
preserving technology to process continuous data in real
time, known as a continuous reversibleprivacy-preserving
(CRP) algorithm. Data with CRP algorithm protection can
be accurately recovered through a data recovery process.
In addition, by using an embedded watermark, the
integrity of the data can be verified. The results from the
experiments show that, compared to existing algorithms,
CRP is better at preserving knowledge and is more
effective in terms of reducing information loss and privacy
disclosure risk. In addition, it takes far less time for CRP to
process continuous data than existing algorithms. As a
result, CRP is confirmed as suitable for data stream
environments and fulfils the requirements of being
lightweight and energy-efficient for smart handheld
devices.
4. PROPOSED WORK
The proposed work is aimed to design and develop a
privacy preserving data model for association rule mining.
In this context a data mining model is proposed. The
different components of the proposed PPDM based
association rule mining model is demonstrated in figure 1.
Fig.- 1:-Proposed solution methodology
In the given solution first a growing transactional data
source is required which collect the data or data
transactions from the different possibleparties.Inorderto
synchronize the data source andtheappearanceofthedata
in the target data source the time based buffer scheme is
developed. That collects the transactionsamplesfromtime
to time. In the third phase the key management or token
management technique is applied to keep in track the
security and privacy of data aggregated into a single
database. The key management of the participatingparties
are managed in such way by which the re-collaboration of
parties are not affected and continuous secure data or rule
outcomes can be available. Finally a central authority
processes the data using the association rule mining
algorithm and distributes the generated rules securely.
5. CONCLUSION
The privacy preserving data mining is relatively new
technique then classical data mining and it’s techniques.
However as the traditional data mining technique the
PPDM techniques utilizing the similar algorithms and
mining techniques but both the approaches are much
similar in their application and data processingabilities.In
this presented paper the different techniques and
applications of privacy preserving data mining techniques
are investigated. Additionally a new PPDM based
association rule mining technique is also described for
design and implementation. The proposed technique is
based on the existing data mining techniques and their
privacy preserving scenarios. Therefore it is a promising
and effective technique that combine goodness o different
PPDM model. This section provides conclusion of the
presented work in this paper and in next section thefuture
extension of the proposed work is presented.
6. FUTURE WORK
This paper provides a study about the privacy preserving
data mining technique. That can be used in a number of
applications where the different parties are combining
their data for finding common decisions. Therefore a new
privacy preserving association rule mining technique is
proposed in this paper. In near future the proposed
technique is implemented using the suitable technology
and their performance is provided with comparativestudy
with the similar technique.
