Using cryptography for privacy protection in data mining systems

To conduct data mining including mining on the web data, we often need to collect data from various parties. Privacy concerns may prevent the parties from directly sharing the data and some types of information about the data. How multiple parties collaboratively conduct data mining without breaching data privacy presents a challenge. In this paper, we present a solution for privacy-preserving k-Medoids clustering which is one of data mining tasks. The solution is based on the cryptography technology.
