An Insight in to Privacy Preserving Data Mining Methods

Abstract

Recent advances in information, communications, data mining, and security technologies have given rise to a new era of research, known as Privacy Preserving Data Mining (PPDM). Several data mining algorithms, incorporating privacy preserving mechanisms, have been developed that allow one to extract relevant knowledge from large amount of data, while hide sensitive data or information from disclosure or inference. PPDM is a new attempt; thus, several research questions have often been asked. For instance: (1) How to measure the performance of these algorithms? (2) How effective of these algorithms in terms of privacy preserving? (3) Will they impact the accuracy of data mining results? and (4) Which one can better protect sensitive information? To help answer these questions, we conduct an extensive review on literature. We present a classification scheme, adopted from early studies, to guide the review process. Finally, we share directions for future research.
