Abstract:
We present Box, a new application platform that prevents apps from misusing information about their users. To strike a useful balance between users privacy and apps functional needs, piBox shifts much of the responsibility for protecting privacy from the app and its users to the platform itself. To achieve this, Box deploys 1 a sandbox that spans the users device and the cloud, 2 specialized storage and communication channels that enable common app functionalities, and 3 an adaptation of recent theoretical algorithms for differential privacy under continual observation. We describe a prototype implementation of Box and show how it enables a wide range of useful apps with minimal performance overhead and without sacricing user privacy
