Noise Addition for Protecting Privacy in Data Mining

In recent years advances in technology facilitated collection and storage of vast amount of data. Many organizations, including large and small businesses, and hospitals and government bodies rely on data for day-to-day operation as well as marketing, planning and research purposes. Examples include criminal records used by law enforcement and national security agencies, medical records used for treatment and research purposes and shopping records used for marketing and enhancing business strategies. The benefits of the information extracted from such data can hardly be overestimated. For example, we are witnessing huge progress made in the human genetic project bringing new promises of previously unimaginable treatments such as gene therapy.
