The privacy preserving in computing offloading

Recently, computing offloading is a technology to solve the problem of the constraint of the mobile device, such as the power, memory and so on. Meantime, when the users decide to offloading, they must make sure that the data cannot be revealed. In this paper presents an overview of the privacy preserving in computing offloading from the perspectives of the offloading strategies, the energy performance, the technologies for privacy and security protecting in computation offloading decision. What's more, this paper give the flowchart of the privacy preserving in computation offloading. Finally, the author describes directions for future researches.
