Two Protocols for Privacy-Preserving Multi-Rank
Zhong Hon · Microcomputer Information · 2010
In semi-honest model,two protocols are proposed which are used to solve the problem of multi-ranking under the condition of privacy-preservation.The semi-honest third party sort anonymous data,and then broadcast the sorted data to all the participants,such that every participant knows the position of his and her data in the permutation array.Last,we analyze the security and computational complexity.
