We have developed Privacy-Preserving Face Finder (P2F2), a system that allows cloud-based photo matching,...
This paper presents Moitree, the middleware of our Avatar platform for mobile cloud computing. Avatar leverages cloud resources to support fast, scalable, reliable, and energy efficient distributed computing over mobile devices. Each mobile device is augmented by an avatar, a per-user always-on software entity that resides in the cloud and acts as the surrogate of the mobile device, to the extent...
With cloud assistance, a mobile application can offload its resource-demanding computation tasks to the cloud (public cloud, cloudlet, or personal cloud, etc). This leads to a scenario where computation tasks in the same application run concurrently on both the mobile device and the cloud. These tasks need to save, read, and write files on both the mobile device and the cloud. An important challenge...
Avatar is a system that leverages cloud resources to support fast, scalable, reliable, and energy efficient distributed computing over mobile devices. An avatar is a per-user software entity in the cloud that runs apps on behalf of the user's mobile devices. The avatars are instantiated as virtual machines in the cloud that run the same operating system with the mobile devices. In this way, avatars...
