Research on the protection algorithm and model of personal privacy information in internet of thing

With the development of information and communication technology, network age coming silently, it will be caused a new personal information leakage risk by the Ubiquitous Computing applications. This paper introduces the individual privacy information forms of expression in networking technology, and then puts forward with the secure multi-party computation to achieve personal information protection. Otherwise, we describe the process and the algorithm of implement. At last, we build in a conceptual model according to the layered theory of the network information on privacy protection.
