The data provided by individuals and various organizations while using internet applications and mobile devices are very useful to generate solutions and create new opportunities. The data which is shared needs to be precise to get the quality results. The data which may contain an individual's sensitive information cannot be revealed to the world without applying some privacy preserving technique on it. Privacy preserving data mining (PPDM) and Privacy preserving data publishing (PPDP) are some of the techniques which can be utilized to preserve privacy. There are some positives and negatives for every technique. The cons frequently constitute loss of data, reduction in the utility of data, compromised diversity of data, reduced security, etc. In this paper, the authors propose a new technique called Remodeling, which works in conjunction with the k-anonymity and K-means algorithm to ensure minimum data loss, better privacy preservation while maintaining the diversity of data. Network data security is also handled by this proposed model. In this research paper, theoretically, we have shown that the proposed technique addresses all the above-mentioned cons and also discusses the merits and demerits of the same.

With the development of network, data collection and storage technology, the use and sharing of large amounts of data has become possible. Once the data and information accumulated, it will become the wealth of information. However, traditional data mining techniques and algorithms directly operated on the original data set, which will cause the leakage of privacy data. At the same time, large amounts of data implicate the sensitive knowledge that their disclosure cannot be ignored to the competitiveness of enterprise. In order to overcome these problems, Privacy Preserving Data Mining (PPDM) techniques are developed. Traditional PPDM techniques suffer from different types of attacks and loss of information. In this paper an alternative method was proposed which provides less information loss and more privacy.
Data mining is beneath the attack of privacy promoters due to confusion regarding what it really is and a accurate concern related how it's normally done. This paper presents how techniques from the community of security can modify data mining for its betterment, allowing all its advantages as it still maintaining its privacy.Large Volumes of precise personal data is regularly gathered and observed by various kinds of applications by the use of data mining, analyzing those data is profitable to the users of the application. It is a significant asset to users of the application such as governments for taking effective decisions or business organizations.

In privacy preserving data mining, anonymization based approaches have been used to preserve the privacy of an individual. Existing literature addresses various anonymization based approaches for preserving the sensitive private information of an individual. The k-anonymity model is one of the widely used anonymization based approach. However, the anonymization based approaches suffer from the issue of information loss. To minimize the information loss various state-of-the-art anonymization based clustering approaches viz. Greedy k-member algorithm and Systematic clustering algorithm have been proposed. Among them, the Systematic clustering algorithm gives lesser information loss. In addition, these approaches make use of all attributes during the creation of an anonymized database. Therefore, the risk of disclosure of sensitive private data is higher via publication of all the attributes. In this paper, we propose two approaches for minimizing the disclosure risk and preserving the...
Data Mining has been the foremost researched space for researchers because of the possibilities of extension at every application of it. Once the information becomes massive in volume, several issues strike for security and privacy breach. If the data changes, it'd be mandatory to rescan the database that results to long computation time and inability to promptly reply to the user. Some applications like sharing of such knowledge to a selected user that have threats of preserving the original data so that the injection of such data can be prohibited. Thus it's a timely need to secure the information whereas handling them to the known or unknown users. Such troubles prompted the advancement of Privacy Preserving Data Mining (PPDM) Techniques. Primary objective is to accomplish harmony between privacy preservation and knowledge discovery and hiding the data from attacker. Privacy Preserving has become a crucial issue within the development progress of Data Mining techniques. Methods like k-anonymity along with the hybrid approach of l-diversity and t-closeness. Experimental outcomes shows that the approach not solely preserve's data privacy however one will get better accuracy with minimum loss of data.
Increasing the business prospective the sharing of data is the most important. But when Sensitive data are share between two parties at that time the privacy of data is the major problem. In day to day life the Sharing, transferring, mining and publishing data are the major factor in privacy preservation. When sensitive data are share between two parties then the privacy of data is the major problem. The main aim of the privacy preservation is protecting the sensitive information in data while extracting knowledge from large amount of data. There are many techniques are use in privacy preservation like k-anonymity, l-diversity, t-closeness, blocking based method and cryptography techniques. Privacy preserving techniques available but still they have shortcomings. Like Anonymity technique gives privacy protection and usability of data but it suffers from homogeneity and background attack. Blocking method suffers from information loss and random perturbation technique does not provide usability of data. Cryptography technique gives privacy protection but does not provide usability of data and it requires more computational overhead. So in this work we use the k-anonymity method to prevent our data and we can get better accuracy as compare to previously used methods.
Privacy preserving has become crucial in knowledge-based applications. And proper integration of individual privacy is essential for data mining operations. This privacy-based data mining is important for sectors such as healthcare, pharmaceuticals, investigation and security service providers, where the data mining is transformed into cooperative task among individuals. Data mining is successful in many applications, data mining refers special concerns for private data. In data mining, clustering algorithms are most of skilled and frequently used frameworks. The integrated architecture takes a systemic view of the problem of implementing established protocols for data collection, inference control, information sharing and keeping information safety. The goal is to investigating privacy preservation issues was to take a systemic view of the architectural requirements and also design principles and explore possible solutions that would lead to the guidelines for buildup practical privacy-preserving data mining systems. In this paper, we propose the methods which uses formula-based technique for sharing of secret data in privacy-preserving mechanism. The process includes formula-based methodology which enables the information to be partitioned into numerous shares and handled independently at various servers. This paper surveys the most relevant Privacy preserving data mining 'PPDM' techniques from the literature are used to evaluate such techniques and presents the typical applications of PPDM methods in relevant fields. The ongoing current challenges and open issues in PPDM are discussed in the paper.

Therefore, the risk of disclosure of sensitive private data is higher via publication of all the attributes. In this paper, we propose two approaches for minimizing the disclosure risk and preserving the privacy by using systematic clustering algorithm. First approach creates an unequal combination of quasi-identifier and sensitive attribute. Second approach creates an equal combination of quasi-identifier and sensitive attribute. We also evaluate our approach empirically focusing on the information loss and execution time as vital metrics. We illustrate the effectiveness of the proposed approaches by comparing them with the existing clustering algorithms.

Data Mining plays a vital role in today's information-oriented world where it has been widely applied in various organizations. The current trend is that organizations need to share data for mutual benefit. This has led to a lot of concern over privacy in the recent years. It has also raised a potential threat of revealing sensitive data of an individual when the data is released publicly. Various methods have been proposed to tackle the privacy preservation problem. But the recurring problem is information loss. The loss of sensitive information about certain individuals may affect the data quality and in extreme cases the data may become completely useless. In recent years Privacy preserving data mining has emerged as a key domain of research. One of the methods used for preserving privacy is k-anonymization. k-anonymity demands that every tuple in the dataset released be indistinguishably related to no fewer than k respondents. But the distribution preservation is not guaranteed. In this work a modified k-anonymity model is introduced where the privacy in a dataset is preserved while preserving the distribution also.
— Privacy preserving data mining has become increasingly popular because it allows sharing of private sensitive data for analysis purposes. The concept of privacy preserving data mining has been proposed in response to these privacy concerns. The main goal of this research work has introduced a new k-Anonymity algorithm which is capable of transforming a non anonymous data set into a k-Anonymity data set. K-Anonymity model is thus to transform a table so that no one can make high-probability associations between records in the table and the corresponding entities. In order to achieve this goal, the K-Anonymity model requires that any record in a table be indistinguishable from at least (k−1) other records with respect to the predetermined quasi-identifier. Finally the modified dataset is used for clustering.
In organization large amount of data are collected daily and these data are used by the organization for data mining tasks. These data collected may contain sensitive attribute which not disclosed by un-trusted user. Privacy is very important when release the data for sharing purpose or mining. Privacy preserving data mining allow publishing data while same time it protect the sensitive or private data. For privacy preserving there are many technique like k-anonymity, cryptography, blocking based, data Perturbation etc. In this paper, various privacy preserving approaches in data sharing and their merits and demerits are analyzed.

Privacy preserving data mining has become increasingly popular because it allows sharing of privacy sensitive data for analysis purposes .So people have become increasingly unwilling to share their data, frequently resulting in individuals either refusing to share their data or providing incorrect data. In recent years, privacy preserving data mining has been studied extensively, because of the wide proliferation of sensitive information on the internet. We discuss method for randomization, kanonymization, and distributed privacy preserving data mining. Knowledge is supremacy and the more knowledgeable we are about information break-in, we are less prone to fall prey to the evil hacker sharks of information technology. In this paper, we provide a review of the state-of-the-art methods for privacy and analyze the representative technique for privacy preserving data mining and points out their merits and demerits. Finally the present problems and directions for future research are discussed.

As with the increasing demand of the data mining techniques the privacy preserving is consider as the important factor. In this paper we discuss to provide the security during data mining technique without compromised the utilization of the data. Individuals are well familiar with the security threats and are averse to share their personal information on network. Because of this the outcome of data mining are negligent. By taking into consideration the privacy factor several techniques were proposed, but these methods are in the state of infancy.The fame of these PPDM techniques is based on the accuracy achieved by these algorithm and performance of the algorithm.Nevertheless there is no such algorithm exist which achieve accuracy as well as better performance. However algorithm those perform better may lack in accuracy factor or vice-versa. In this paper we discuss about various methods for ensuring security in data mining and also explore the direction of the future research work.

Data mining is the process of extracting interesting patterns or knowledge from huge amount of data. In recent years, there has been a tremendous growth in the amount of personal data that can be collected and analyzed by the organizations. As hardware costs go down, organizations find it easier than ever to keep any piece of information acquired from the ongoing activities of their clients. These organizations constantly seek to make better use of the data they possess, and utilize data mining tools to extract useful knowledge and patterns from the data. Also, the current trend in business collaboration shares the data and mine results to gain mutual benefit [2]. This data does not include explicit identifiers of an individual like name or address but it does contain data like date of birth, pin code, sex, marital-status etc. which when combined with other publicly released data like voter registration data can identify an individual. The previous literature of privacy preserving data publication has focused on performing “one-time” releases. Specifically, none of the existing solutions supports re-publication of the micro data multiple time publishing, after it has been updated with insertions and deletions. This is a serious drawback, because currently a publisher cannot provide researchers with the most recent dataset continuously. Based on survey of theoretical analysis, we develop a new generalization principle l-scarcity that effectively limits the risk of privacy disclosure in re-publication. And it’s a new method modifying of l-diversity and m-invariance by combining of these two methods. They provide a privacy on re-publication of the microdata. We consider a more realistic setting of sequential releases by Insertions, deletions and updates and Transient/permanent values. We cannot simply adapt these existing privacy models to this realistic setting.
In many organizations large amount of data are collected. These data are sometimes used by the organizations for data mining tasks. However, the data collected may contain private or sensitive information which should be protected. Privacy protection is an important issue if we release data for the mining or sharing purpose. Privacy preserving data mining techniques allow publishing data for the mining purpose while at the same time preserve the private information of the individuals. Many techniques have been proposed for privacy preservation but they suffer from various types of attacks and information loss. In this paper we proposed an efficient approach for privacy preservation in data mining. Our technique protects the sensitive data with less information loss which increase data usability and also prevent the sensitive data for various types of attack. Data can also be reconstructed using our proposed technique.

The data available is vast and data is being analyzed to improve businesses. This data analysis also contributes to society in different ways. Now there are new challenges to protect privacy of data. So, Privacy Preserving Data Mining (PPDM) techniques have evolved which protect the privacy of data while carrying out data analysis. Privacy Preserving Data Publishing (PPDP) is a part of PPDM which is a major research area. As part of PPDP several anonymization algorithms are proposed. Kanonymization is one among them. In this paper a new method for privacy preserving data mining is proposed which is better than applying k-anonymization alone. The present research work focuses on the approach which decreases the risk of various attacks and at the same time provides more utility of data.

Privacy preserving data mining has emerged due to large usage of data in organizations for extracting knowledge from data[1]. Big data uses centralized as well as distributed data and mines knowledge. Privacy preservation of data has become critical asset due to malicious users and society issues. It is very crucial nowadays to maintain balance between ensuring privacy and extracting knowledge. These areas is burning domain for researchers till now because no such research has been done that out performs all the techniques in privacy preserving data mining. Privacy preservation is classified into many categories like data modification, data distribution, data hiding and data encryption. For performance measuring, evaluation criteria like information loss, computational overhead, data utility etc are considered. Data modification techniques mainly focus on adding errors to data or results into output which degrades the accuracy of data mining algorithm. In case of critical analysis of data, crypto graphical approaches in privacy preserving data mining which has no loss of information but overhead of computation and communication have been adopted. PPDM includes homomorphic encryption, Shamir's secret sharing scheme, oblivious transfer and many other cryptography techniques.

The Privacy preserving Data mining (PPDM) has been among the important issues of current research that deals with preserving privacy of individual's data over a network. The major area of concern is that non-sensitive data even may deliver sensitive information, including personal information, facts or patterns. In this paper, we present a unique concept of combining different PPDM techniques which provides high level security and integrity to confidential data. This paper mainly highlights the improved results that can be obtained on merging the two different PPDM techniques. One of the latest concept of PPDM called Slicing has also been explained in our paper. It has been observed that slicing preserves better data utility and thus we have tried to merge slicing with one of the best security mechanism that is Cryptography.
