This paper proposes HDPPDK-Means clustering algorithm for privacy-preserving over horizontal partitioned database, using secure multi-party computation protocol to realize privacy-preserving of clustering algorithm. Theoretical analysis and examples illustrate that the proposed algorithm can effectively solve privacy-preserving problem of clustering mining(More)
It has been a significant research subject that how to extract valuable knowledge in data and to preserve private or sensitive information in data mining process from leaking. By comparing and analyzing privacy-preserving data mining algorithm, the paper has established the classification frame of privacy-preserving algorithm, found the opening of present(More)
