The mobile cloud computing paradigm involves communications between Smartphones and their virtual (software) clones in the cloud. It offers both backup/recovery solutions as well as offload of mobile computations, increasing the communication and computation capabilities of Smartphones and making their limited batteries last longer. Unfortunately, in this scenario, the privacy of the users is at stake. The cellular network operator knows how often users contact the cloud, and the cloud provider knows how often users' clones contact each other. The authors address this privacy problem by providing an anonymous communication protocol, leveraging properties of social networks and ad-hoc wireless networks.
