An Overview of Privacy Preserving Data Mining

In recent years, wide available personal data has made privacy preserving data mining issue an important one. An overview of new and rapidly emerging research field of privacy preserving data mining and some exist problems provided in this paper. We also make a classification for the privacy preserving data mining, and analyze some works in this field. Data distortion method for achieving privacy protection association rule mining and privacy protection data release were focused on discussion. Detailed evaluation criteria of privacy preserving algorithm was illustrated, which include algorithm performance, data utility, privacy protection degree, and data mining difficulty. Finally, the development of privacy preserving data mining for further directions is prospected.
