Abstract:

This paper first introduces the privacy-preserving outlier detection and secure multi-party computation, and then proposes a new algorithm for secure addition computation, which resolves the collusion in multi-party addition effectively. By applying it to the privacy-preserving outlier detection over  horizontally partitioned databases, we present a secure algorithm for such a detection. Finally,we give the computational complication and the cost of c  ommunications.
