Research on key technologies of mobile crowd sensing for privacy-preserving

Abstract

Mobile crowd sensing is a new type of sensing mode and has been widely used. However, mobile crowd sensing requires a large number of users to participate in the execution of sensing tasks, and in the process of executing sensing tasks, users may face the risk of privacy information leakage. Therefore, how to protect the privacy of users is one of the key issues to be solved in the field of mobile crowd sensing. Accordingly, this paper studies the privacy-preserving mechanisms in the field of mobile crowd sensing, and summarizes the existing privacy-preserving research, so as to provide a reference for the in-depth research of mobile crowd sensing.
