This paper proposes a classification-based approach for suppressing data to prevent sensitive information from being inferred. It uses decision tree algorithms to classify data elements based on attributes and considers suppressing data elements to secure the data. The paper aims to enhance data classification and generalization. It shows how data can be secured using "generalization" while maintaining usefulness for data mining tasks. The proposed system focuses on data generalization concepts to hide detailed information for privacy while allowing standard data mining techniques to still discover patterns. It evaluates suppressing multiple confidential values and developing a technique independent of individual classification methods based on information theory.
Efficient classification of big data using vfdt (very fast decision tree)eSAT Journals
Abstract
Decision Tree learning algorithms have been able to capture knowledge successfully. Decision Trees are best considered when
instances are described by attribute-value pairs and when the target function has a discrete value. The main task of these
decision trees is to use inductive methods to the given values of attributes of an unknown object and determine an
appropriate classification by applying decision tree rules. Decision Trees are very effective forms to evaluate the performance
and represent the algorithms because of their robustness, simplicity, capability of handling numerical and categorical data,
ability to work with large datasets and comprehensibility to a name a few. There are various decision tree algorithms available
like ID3, CART, C4.5, VFDT, QUEST, CTREE, GUIDE, CHAID, CRUISE, etc. In this paper a comparative study on three of
these popular decision tree algorithms - (Iterative Dichotomizer 3), C4.5 which is an evolution of ID3 and VFDT (Very
Fast Decision Tree has been made. An empirical study has been conducted to compare C4.5 and VFDT in terms of accuracy
and execution time and various conclusions have been drawn.
Key Words: Decision tree, ID3, C4.5, VFDT, Information Gain, Gain Ratio, Gini Index, Over−fitting.

CLUSTERING DICHOTOMOUS DATA FOR HEALTH CAREijistjournal
Dichotomous data is a type of categorical data, which is binary with categories zero and one. Health care data is one of the heavily used categorical data. Binary data are the simplest form of data used for heath care databases in which close ended questions can be used; it is very efficient based on computational efficiency and memory capacity to represent categorical type data. Clustering health care or medical data is very tedious due to its complex data representation models, high dimensionality and data sparsity. In this paper, clustering is performed after transforming the dichotomous data into real by wiener transformation. The proposed algorithm can be usable for determining the correlation of the health disorders and symptoms observed in large medical and health binary databases. Computational results show that the clustering based on Wiener transformation is very efficient in terms of objectivity and subjectivity.
Distributed Digital Artifacts on the Semantic WebEditor IJCATR
Distributed digital artifacts incorporate cryptographic hash values to URI called trusty URIs in a distributed environment
building good in quality, verifiable and unchangeable web resources to prevent the rising man in the middle attack. The greatest
challenge of a centralized system is that it gives users no possibility to check whether data have been modified and the communication
is limited to a single server. As a solution for this, is the distributed digital artifact system, where resources are distributed among
different domains to enable inter-domain communication. Due to the emerging developments in web, attacks have increased rapidly,
among which man in the middle attack (MIMA) is a serious issue, where user security is at its threat. This work tries to prevent MIMA
to an extent, by providing self reference and trusty URIs even when presented in a distributed environment. Any manipulation to the
data is efficiently identified and any further access to that data is blocked by informing user that the uniform location has been
changed. System uses self-reference to contain trusty URI for each resource, lineage algorithm for generating seed and SHA-512 hash
generation algorithm to ensure security. It is implemented on the semantic web, which is an extension to the world wide web, using
RDF (Resource Description Framework) to identify the resource. Hence the framework was developed to overcome existing
challenges by making the digital artifacts on the semantic web distributed to enable communication between different domains across
the network securely and thereby preventing MIMA.

An apriori based algorithm to mine association rules with inter itemset distanceIJDKP
Association rules discovered from transaction databases can be large in number. Reduction of association
rules is an issue in recent times. Conventionally by varying support and confidence number of rules can be
increased and decreased. By combining additional constraint with support number of frequent itemsets can
be reduced and it leads to generation of less number of rules. Average inter itemset distance(IID) or
Spread, which is the intervening separation of itemsets in the transactions has been used as a measure of
interestingness for association rules with a view to reduce the number of association rules. In this paper by
using average Inter Itemset Distance a complete algorithm based on the apriori is designed and
implemented with a view to reduce the number of frequent itemsets and the association rules and also to
find the distribution pattern of the association rules in terms of the number of transactions of non
occurrences of the frequent itemsets. Further the apriori algorithm is also implemented and results are
compared. The theoretical concepts related to inter itemset distance are also put forward.
Privacy Preservation and Restoration of Data Using Unrealized Data SetsIJERA Editor
In today’s world, there is an improved advance in hardware technology which increases the capability to store and record personal data about consumers and individuals. Data mining extracts knowledge to support a variety of areas as marketing, medical diagnosis, weather forecasting, national security etc successfully. Still there is a challenge to extract certain kinds of data without violating the data owners’ privacy. As data mining becomes more enveloping, such privacy concerns are increasing. This gives birth to a new category of data mining method called privacy preserving data mining algorithm (PPDM). The aim of this algorithm is to protect the easily affected information in data from the large amount of data set. The privacy preservation of data set can be expressed in the form of decision tree. This paper proposes a privacy preservation based on data set complement algorithms which store the information of the real dataset. So that the private data can be safe from the unauthorized party, if some portion of the data can be lost, then we can recreate the original data set from the unrealized dataset and the perturbed data set.
An Analysis of Outlier Detection through clustering methodIJAEMSJORNAL
This research paper deals with an outlier which is known as an unusual behavior of any substance present in the spot. This is a detection process that can be employed for both anomaly detection and abnormal observation. This can be obtained through other members who belong to that data set. The deviation present in the outlier process can be attained by measuring certain terms like range, size, activity, etc. By detecting outlier one can easily reject the negativity present in the field. For instance, in healthcare, the health condition of a person can be determined through his latest health report or his regular activity. When found the person being inactive there may be a chance for that person to be sick. Many approaches have been used in this research paper for detecting outliers. The approaches used in this research are 1) Centroid based approach based on K-Means and Hierarchical Clustering algorithm and 2) through Clustering based approach. This approach may help in detecting outlier by grouping all similar elements in the same group. For grouping, the elements clustering method paves a way for it. This research paper will be based on the above mentioned 2 approaches.

A Rule based Slicing Approach to Achieve Data Publishing and Privacyijsrd.com
several anonymization techniques, such as generalization and bucketization, have been designed for privacy preserving micro data publishing. Recent work has shown that generalization loses considerable amount of information, especially for high dimensional data. Bucketization, on the other hand, does not prevent membership disclosure and does not apply for data that do not have a clear separation between quasi-identifying attributes and sensitive attributes. The existing system proposed slicing concept to overcome the tuple based partition this has been done to overcome the previous generalization and bucketization. In this paper, present a novel technique called rule based slicing, which partitions the data both horizontally and vertically. We show that slicing preserves better data utility than generalization and can be used for membership disclosure protection. Another important advantage of slicing is that it can handle high-dimensional data. We show how slicing can be used for attribute disclosure protection and develop an efficient algorithm for computing the sliced data that obey the l-diversity requirement. The workload experiments confirm that slicing preserves better utility than generalization and is more effective than bucketization in workloads involving the sensitive attribute. The experiments also demonstrate that slicing can be used to prevent membership disclosure

Comparative study of ksvdd and fsvm for classification of mislabeled dataeSAT Journals
Abstract Outlier detection is the important concept in data mining. These outliers are the data that differ from the normal data. Noise in the
application may cause the misclassification of data. Data are more likely to be mislabeled in presence of noise leading to
performance degradation. The proposed work focuses on these issues. Data before classifying is given a value that represents its
willingness towards the class. This data with likelihood value is then given to classifier to predict the data. SVDD algorithm is
used for classification of data with likelihood values.

sis of health condition is very challenging task for every human being because life is directly related to health
condition. Data mining based classification is one of the important applications for classification of data. In this
research work, we have used various classification techniques for classification of thyroid data. CART gives highest
accuracy 99.47% as best model. Feature selection plays very important role to computationally efficient and increase
the performance of model. This research work focus on Info Gain and Gain Ratio feature selection technique to
reduce the irrelevant features from original data set and computationally increase the performance of model. We have
applied both the feature selection techniques on best model i. e. CART. Our proposed CART-Info Gain and CARTGain

A Comparative Study on Privacy Preserving Datamining TechniquesIJMER
Privacy protection is very important in the recent years for the reason of increasing in the
ability to store data. In particular, recent advances in the data mining field have lead to increased
concerns about privacy. Data in its original form, however, typically contains sensitive information about
individuals, and publishing such data will violate individual privacy. The current practice in data
publishing based on that what type of data can be released and use of that data. Recently, PPDM has
received immersed attention in research communities, and many approaches have been proposed for
different data publishing scenarios. In this comparative study we will systematically summarize and
evaluate different approaches for PPDM, study the challenges ,differences and requirements that
distinguish PPDM from other related problems, and propose future research directions
A Codon Frequency Obfuscation Heuristic for Raw Genomic Data PrivacyKato Mivule
Genomic data provides clinical researchers with vast opportunities to study various patient ailments. Yet the same data contains revealing information, some of which a patient might want to remain concealed. The question then arises: how can an entity transact in full DNA data while concealing certain sensitive pieces of information in the genome sequence, and maintain DNA data utility? As a response to this question, we propose a codon frequency obfuscation heuristic, in which a redistribution of codon frequency values with highly expressed genes is done in the same amino acid group, generating an obfuscated DNA sequence. Our preliminary results show that it might be possible to publish an obfuscated DNA sequence with a desired level of similarity (utility) to the original DNA sequence. http://arxiv.org/abs/1405.5410

This paper presents an automated solution for the problem of data cleansing and recognition of user written data to transform into standard printed format with the help of artificial neural networks. Three different neural models namely direct, correlation based and hierarchical have been developed to handle this issue. In a very hostile input environment, the solution is developed to justify the proposed logic.
Abstract In this paper, the concept of data mining was summarized and its significance towards its methodologies was illustrated. The data mining based on Neural Network and Genetic Algorithm is researched in detail and the key technology and ways to achieve the data mining on Neural Network and Genetic Algorithm are also surveyed.

Using Randomized Response Techniques for Privacy-Preserving Data Mining14894
Privacy is an important issue in data mining and knowledge
discovery. In this paper, we propose to use the randomized
response techniques to conduct the data mining computation.
Specially, we present a method to build decision tree
classifiers from the disguised data. We conduct experiments
to compare the accuracy ofou r decision tree with the one
built from the original undisguised data. Our results show
that although the data are disguised, our method can still
achieve fairly high accuracy. We also show how the parameter
used in the randomized response techniques affects the
accuracy ofth e results

With the development of database, the data volume stored in database increases rapidly and in the large
amounts of data much important information is hidden. If the information can be extracted from the
database they will create a lot of profit for the organization. The question they are asking is how to extract
this value. The answer is data mining. There are many technologies available to data mining practitioners,
including Artificial Neural Networks, Genetics, Fuzzy logic and Decision Trees. Many practitioners are
wary of Neural Networks due to their black box nature, even though they have proven themselves in many
situations. This paper is an overview of artificial neural networks and questions their position as a
preferred tool by data mining practitioners.

there could be some sensitive data which should not be
disclosed to the other parties. Also medical records are more
sensitive so, privacy protection is taken more seriously. As
required by the Health Insurance Portability and
Accountability Act (HIPAA), it is necessary to protect the
privacy of patients and ensure the security of the medical
data. To address this problem, released datasets must be
modified unavoidably. We propose a method called Hybrid
approach for privacy preserving and implemented it. First we
randomized the original data. Then we have applied
generalization on randomized or modified data. This
technique protect private data with better accuracy, also it can
reconstruct original data and provide data with no information
loss, makes usability of data.
Privacy preservation techniques in data miningeSAT Journals
Abstract In this paper different privacy preservation techniques are compared. Classification is the most commonly applied data mining technique, which employs a set of pre-classified examples to develop a model that can classify the population of records at large. Fraud detection and credit risk applications are particularly well suited to this type of analysis. This approach frequently employs decision tree or neural network-based classification algorithms. The data classification process involves learning and classification. In Learning the training data are analyzed by classification algorithm. In classification test data are used to estimate the accuracy of the classification rules. If the accuracy is acceptable the rules can be applied to the new data tuples . For a fraud detection application, this would include complete records of both fraudulent and valid activities determined on a record-by-record basis. The classifier-training algorithm uses these pre-classified examples to determine the set of parameters required for proper discrimination. The algorithm then encodes these parameters into a model called a classifier Index Terms: Data Mining, Privacy Preservation, Clustering, Classification Techniques, Naive Bayes.

Perfomance Comparison of Decsion Tree Algorithms to Findout the Reason for St...ijcnes
Educational data mining is used to study the data available in the educational field and bring out the hidden knowledge from it. Classification methods like decision trees, rule mining can be applied on the educational data for predicting the students behavior. This paper focuses on finding thesuitablealgorithm which yields the best result to find out the reason behind students absenteeism in an academic year. The first step in this processis to gather students data by using questionnaire.The datais collected from 123 under graduate students from a private college which is situated in a semirural area. The second step is to clean the data which is appropriate for mining purpose and choose the relevant attributes. In the final step, three different Decision tree induction algorithms namely, ID3(Iterative Dichotomiser), C4.5 and CART(Classification and Regression Tree)were applied for comparison of results for the same data sample collected using questionnaire. The results were compared to find the algorithm which yields the best result in predicting the reason for student s absenteeism.
Privacy Preserving Approaches for High Dimensional Dataijtsrd
This paper proposes a model for hiding sensitive association rules for Privacy preserving in high dimensional data. Privacy preservation is a big challenge in data mining. The protection of sensitive information becomes a critical issue when releasing data to outside parties. Association rule mining could be very useful in such situations. It could be used to identify all the possible ways by which ˜non-confidential data can reveal ˜confidential data, which is commonly known as ˜inference problem. This issue is solved using Association Rule Hiding (ARH) techniques in Privacy Preserving Data Mining (PPDM). Association rule hiding aims to conceal these association rules so that no sensitive information can be mined from the database.

A SURVEY ON PRIVACY PRESERVING ASSOCIATION RULE MININGijdkp
Businesses share data, outsourcing for specific business problems. Large companies stake a large part of
their business on analysis of private data. Consulting firms often handle sensitive third party data as part of
client projects. Organizations face great risks while sharing their data. Most of this sharing takes place with
little secrecy. It also increases the legal responsibility of the parties involved in the process. So, it is crucial to
reliably protect their data due to legal and customer concerns. In this paper, a review of the state-of-the-art
methods for privacy preservation is presented. It also analyzes the techniques for privacy preserving
association rule mining and points out their merits and demerits. Finally the challenges and directions for
future research are discussed.
In this era, there are need to secure data in distributed database system. For collaborative data
publishing some anonymization techniques are available such as generalization and bucketization. We consider
the attack can call as “insider attack” by colluding data providers who may use their own records to infer
others records. To protect our database from these types of attacks we used slicing technique for anonymization,
as above techniques are not suitable for high dimensional data. It cause loss of data and also they need clear
separation of quasi identifier and sensitive database. We consider this threat and make several contributions.
First, we introduce a notion of data privacy and used slicing technique which shows that anonymized data
satisfies privacy and security of data which classifies data vertically and horizontally. Second, we present
verification algorithms which prove the security against number of providers of data and insure high utility and
data privacy of anonymized data with efficiency. For experimental result we use the hospital patient datasets
and suggest that our slicing approach achieves better or comparable utility and efficiency than baseline
algorithms while satisfying data security. Our experiment successfully demonstrates the difference between
computation time of encryption algorithm which is used to secure data and our system.
DCOM (Distributed Component Object Model) and CORBA (Common Object Request Broker Architecture) are two popular distributed object models. In this paper, we make architectural comparison of DCOM and CORBA at three different layers: basic programming architecture, remoting architecture, and the wire protocol architecture.
TUPLE VALUE BASED MULTIPLICATIVE DATA PERTURBATION APPROACH TO PRESERVE PRIVA...IJDKP
Huge volume of data from domain specific applications such as medical, financial, library, telephone,
shopping records and individual are regularly generated. Sharing of these data is proved to be beneficial
for data mining application. On one hand such data is an important asset to business decision making by
analyzing it. On the other hand data privacy concerns may prevent data owners from sharing information
for data analysis. In order to share data while preserving privacy, data owner must come up with a solution
which achieves the dual goal of privacy preservation as well as an accuracy of data mining task –
clustering and classification. An efficient and effective approach has been proposed that aims to protect
privacy of sensitive information and obtaining data clustering with minimum information loss

ABSTRACT
Data mining plays an important role in internet with the
computer technology this makes easy to collect the
information from the related data sets. The different methods
used in this paper are decision tree algorithm, the decision tree
algorithm used hears is to classify the data elements by
considering a set of constraints, we consider this method to
suppress the data by doing so we can secure the data. We
extend our work on micro data suppression (1) to prevent not
only probabilistic but also decision tree classification based
inference, and (2) to handle not only single but also multiple
confidential data value suppression to reduce the side-effects.
The paper aims to enhance the Data classification and Data
Generalization. It shows that how the data is secured using
‗Generalization‘ and moreover. It provides efficiency in Data
Generalization and discusses some of the major challenges for
what kind of data to be suppressed. We consider the following
privacy problem: a data holder wants to release a version of
data for building classification models, but wants to protect
against linking the released data to an external source for
inferring sensitive information. The generalized data remains
useful to classification but becomes difficult to link to other
sources. The generalization space is specified by a
hierarchical structure of generalizations. A key is identifying
the best generalization to climb up the hierarchy at each
iteration. Enumerating all candidate generalizations is
impractical.
Key words: Data classification, Data security, Data
generalization, Data mining.
1. INTRODUCTION
In tandem with the advances in networking and storage
technologies, the private sector as well as the Public sector
has increased their efforts to gather, and manipulate
information on a large scale. Non governmental organization
collects information about there customer or members for
many reasons including better customer relationship
management and high level decision making. This pervasive
data-harvesting effort coupled with the increasing need to
share the data with other institutions or with public raised
concerns about privacy is the ability of an individual to
prevent information about himself becoming known to other
people with out his approval [1]. More specifically it is the
right of individuals to have the control over the data they
provide. This includes controlling, (1) How the data are going
to be used? (2) Who is going to use it? (3) For what purpose?
2. EXISTING SYSTEM
In the Existing System, the basic idea of the design is to
collect the data from the user and classify the data using
classification algorithms like decision tree classification.
For classification we use different techniques like ID3,
maximum impact data attributes, next best guess, but we
found that this method does not work well for securing the
data. Some of the Problem in using ID3 algorithms depends
on the number of attributes, ensuring that the success rate of
these algorithms will always be higher than the other
algorithms if the number of attributes is higher than the
number of transactions. Also depend both on the number of
attributes and the number of transactions.
A.DECISION TREE
A decision tree is a flow chart-like tree structure, where each
internal node (non leaf node) denotes a test on an attribute,
each branch represents an outcome of the test, and each leaf
node (terminal node) holds a class label. The top most nodes
in a tree are the root node [2].
Example 1
Figure
1: Decision tree
The figure 1 is a decision tree for the concept bugs-computer,
indicating whether a customer at ‗All Electronics‘ is likely to
purchase a computer. Each internal (no leaf) node represents a
test on an attribute. Each leaf node represents a class (either
buys-computer= yes or buys-computer=no)
B.“How is decision trees used for classification?”
Given a tuple, X, for which the associated class; able is
unknown; the attribute values of the tuple are tested against
the decision tree. A path is traced from the root to a leaf node,
which holds the class prediction for that tuple. Decision tree
can easily be converted to classification rules [2].

C. Generate-decision-tree
Aim: Generate a decision tree from the training tuples of data
partition D.
Input:
Data partition, D, which is a set of training tuples and
their associated class labels;
Attribute-list, the set of candidate attributes.
Attribute-Selection-method, a procedure to determine
the splitting criterion that ―beat‖ partitions the data tuples into
individual classes.
This criterion consists of a splitting-attribute and, possibly,
either a split point or splitting subset.
Out put: A decision tree
Method
1. Create a node N;
2. if tuples in D are all of the same class, C then
3. return N as a leaf node labeled with the
majority class C;
4. if attribute-list is empty then
5. Return N as a leaf node labeled with the majority
class in D; // majority voting.
6. Apply Attribute-selection method (D, attribute-list)
to find the ―best‖ splitting-criterion;
7. lable node N with splitting-criterion;
8. If splitting-attribute is allowed then // not restricted
to binary trees.
9. Attribute-listattribute-list—splitting—attribute; //
remove splitting-attribute.
10. For each outcome j of splitting-criterion// partition
the tuples and grow sub trees for each partition.
11. let Dj be the set of data tuples in D satisfying
outcome j;// a partition
12. if Dj is empty then
13. attach a leaf labeled with the majority class in D to
node N;
14. else attach the node returned by Generate-decision-
tree (Dj, attribute-list) to node N; end for
15. return N;
D. Bayesian classification
“What are Bayesian Classifiers?”
Bayesian classifiers are statistical classifiers. They can predict
class membership probabilities, such as the probability that a
given tuple belongs to a particular class. Bayesian
classification is based on ―Bayes‘ theorem‖.
Baye’s Theorem
Let X be the data tuple, is considered ―evidence‖. It is
described by measurements made on a set of n attributes. Let
H be some hypothesis, such as the data tuple X belongs to a
specified class C. for classification problem we have to
determine P (H/X), the probability that the hypothesis H holds
given the ―evidence‖ or observed data tuple X [2].
“How are these probabilities estimated?”
P (H), P (X/H), and P (X) may be estimated from the given
data. Bayes theorem provides a way of calculating the
posterior probability, P (H/X) from P (H), P (X/H) and P (X).
P (H/X) = P (X/H) * P (H)/P(X)
E. Data Suppression
The most common method of preventing the identification of
specific individuals in tabular data is through cell suppression.
This means not providing counts in individual cells where
doing so would potentially allow identification of a specific
person. Cell suppression can also be done by combining cells
from different small groups to create larger groupings that
reduce the risk of identifying individuals While there are also
more sophisticated data perturbation methods that use
statistical noise to mask sensitive information, these are
generally more suitable for use with economic or financial
data than with public health data. This appendix reviews the
basic methods, issues, strengths, and vulnerabilities of cell
suppression. In possible statistical unreliability of estimates
that are based on small numbers [4].
F. Suppression Criteria
Suppression rules are typically based on a predetermined
criterion for the number of diagnosed cases and/or the number
of births in the population or subpopulation from which the
cases were identified. These numbers may also be thought of
as the numerator and the denominator, respectively, of a
prevalence estimate. In practice, the rules used vary from
relatively liberal to very conservative [5].
Having made the decision to suppress, the question becomes
what and how to suppress. The solution that provides the
greatest protection of privacy is to suppress an entire table
whenever a single cell presents a threat, whereas the solution
that provides the least protection is to suppress a single
offending cell or only those cells deemed sensitive.
3. PROPOSED SYSTEM
In the proposed system the paper mainly concentrates on the
generalization concepts. The idea is simple but novel: we
explore the data generalization concept from data mining as a
way to hide detailed information, rather than discover trends
and patterns. Once the data is masked, standard data mining
techniques can be applied without modification. Our work
demonstrated another positive use of data mining technology:
not only can it discover useful patterns, but also mask private
information.
A. Anonymity:
The virtual identifier, denoted VID, is the set of attributes
shared by R and E. a (vid) denotes the number of records in R
with the value vid on VID. The anonymity of VID, denoted A
(VID), is the minimum a(vid) for any value vid on VID. If a
(vid) = A (VID), vid is called an anonymity vid. R satisfies
the anonymity requirement < VID; K > if A (VID) ¸ K, where
K is specified by the data holder. We transform R to satisfy
the anonymity requirement by generalizing specific values on
VID into less specific but semantically consistent values. The
generalization increases the probability of having a given
value on VID by chance, therefore, decreases the probability
that a linking through this value represents a real life fact. The
generalization space is specified through a taxonomical
hierarchy per attribute in VID, provided by either the data
holder or the data recipient. A hierarchy is a tree with leaf
nodes representing domain values and parent nodes
representing less specific values. R is generalized by a
sequence of generalizations, where each generalization
replaces all child values c with their parent value p in a
hierarchy. Before a value c is generalized, all values below c
should be generalized to c first.
Generalization:
A generalization, written {c} p, replaces all child values
{c} with the parent value p. A generalization is valid if all
values below c have been generalized to c. A vid is
generalized by {c} p if the vid contains some value in {c}.

2., Anonymity for Classification:
Given a relation R, an anonymity requirement <VID,K>,
and a hierarchy for each attribute in VID, generalize R, by a
sequence of generalizations, to satisfy the requirement and
contain as much information as possible for classification.
The anonymity requirement can be satisfied in more than one
way of generalizing R, and some lose more information than
others with regard to classification. One question is how to
select a sequence of generalizations so that information loss is
minimized. Another question is how to find this sequence of
generalizations efficiently for a large data set.
4 ANALYSIS
Figure 3: Comparison of classification
5 CONCLUSION
In final classification and Generalization will be analyzed.
The paper mainly concentrates on the issues like:
Suppressing confidential data values against other
classification algorithms, e.g., logistic regression
Suppressing multiple confidential data values at a
time (generic version having no constraints),
Developing a generic suppression technique,
independent from individual classification methods, based on
information theory,
Using generalization as a fine grained method, and
Suppressing evolving (i.e., continuously updated) micro data.
First objective is to evaluate the quality of generalized data for
classification, compared to that of the unmodified data.
Second objective is to evaluate the scalability of the proposed
algorithm and generate the generalized report on the data.
