Abstract:

With the aid of secure scalar product protocol, a privacy-preserving vector equivalency determination protocol is proposed. Based on privacypreserving vector equivalency determination protocol, a privacy-preserving dynamic point distance determination protocol based on semihonest and an n-dimension privacy -preserving dynamic point distance determination protocol are presented. The correctness and security are also analyzed. At the end, a general solution to a privacypreserving dynamic point distance determination is discussed.

Key words: cryptograph, secure multi -party computation, secure computational geometry, vector equivalency determination protocol, dynamic point distance determination
