Privacy Preserving Data Mining in Telecommunication Services

Privacy preserving data mining is a new research direction in data mining and knowledge discovery. A main reason for the rapid development of this research area is the growing awareness of the accumulation of huge amounts of easily available data on the Internet - data that may involve a threat to the privacy of users. The problem of user privacy is even more critical for telecommunication applications since they enable user mobility, which in turn may involve accumulation of sensitive spatial data. Such data can for instance reveal driving habits, etc. This paper gives an overview of selected approaches in the area of privacy preserving data mining, with special focus on approaches that are suitable for developing privacy preserving applications in the area of telecommunication.
