A Simple RFID-Based Architecture for Privacy Preservation

With the rapid development of the internet of things all over the world, it is very promising to investigate one of main issues, i.e., localization. However, it has also brought a challenge to the privacy, where the source privacy and location privacy are concerned in this paper. We first review some approaches to deal with the source privacy and location privacy, respectively. Then a simple radio frequency identification (RFID) based architecture is proposed in this paper to preserve the privacy of the target object. This architecture can effectively hide the presence of the target object against adversaries. Meanwhile, the location information of the target object can also be preserved by simply transferring the ID information, rather than the location information. Compared with other approaches, it is convenient to implement the proposed architecture to protect the privacy without high computational complexity and additional supplements. Finally, the privacy analysis is presented to demonstrate the performance of the proposed architecture in terms of the source and location privacy preservation.
