Zhe Jia · Beijing Youdian Xueyuan xuebao · 2012
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.
