Privacy-Preserving Data Mining also an essential branch of the data mining and an exciting topic in privacy preservation has gain particular attention in current years. Data mining has been substantially studied and useful into numerous fields which include the Internet of Things and the business growth. However, data mining tactics additionally take vicinity critical demanding situations due to enlarged sensitive statistics disclosure and the violation of privacy. This discussion describes the privacy concern that occurs due to data mining, particularly for the national security applications. We discuss PPDM by Anonymization Method in which we use K-means clustering in order to divide the given data and DES algorithm for encryption of data in order to prevent sensitive data from attacker. Keywords: privacy preservation, PPDM, K-meanS clustering, anonymization ,DES etc.
I. INTRODUCTIONPrivacy is receiving extra attention partially as of counter-terrorism and the national security. At present we have heard so much approximately countrywide protection in media. This is mainly because people are now realizing that to handle terrorism, the government may need to collect information about individuals. There been much interest in the recent on applying the sa mining used to detect patterns which are unusual , terrorist activities and the fraudulent behavior. While all applications of data mining can give profit to the humans and save lives, there also negative side to this type of method , it could be a danger to the individuals privacy . This is due to data mining tools are present on the Web or, and even naive individuals can use these tools to mine information from stored data in various databases and files, and therefore violate the privateness of individuals. As we have stressed in papers to take out efficient data mining and mine necessary information for counter terrorism and national security, we gather all kinds of information about individuals.[1] However, this information could be a threat to individuals' privacy and civil liberties. This is causing major concern with different civil liberties unions. The aim is to carry out data mining and yet to the maintain privacy. This topic is known as privacy-preserving data mining . In this paper we use anonymization technique along with K-means clustering and DES algorithm.
