Abstract

Electronic devices we use on a daily basis collect sensitive information without preserving user’s privacy. In this paper, we propose the lord of the sense (LotS), a privacy pre- serving reputation system for participatory sensing applications. Our system maintains the privacy and anonymity of information with the use of cryptographic techniques and combines voting approaches to support users’ reputation. Furthermore, LotS maintains accountability by tracing back a misbehaving user while maintaining k-anonymity. A detailed security analysis is presented with the current advantages and disadvantages of our system.
