Survey on privacy preservation in IoT
物联网隐私保护研究与方法综述

By establishing the architecture of IoT, this paper analyzed the privacy threats faced by sensor layer and process layer of the architecture in detail. It summarized the current privacy-preserving methods associated with IoT systemically, especially for methods of anonymization, encryption and routing protocols. At the end of the paper, it pointed out future research directions on privacy-preserving for IoT.
