Platform for Privacy-Preserving Apps.

摘要

We present Box, a new application platform that preventsapps from misusing information about their users.To strike a useful balance between users privacy andapps functional needs, Box shifts much of the responsibilityfor protecting privacy from the app and its usersto 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 enablecommon app functionalities, and (3) an adaptationof recent theoretical algorithms for differential privacyunder continual observation.We describe a prototype implementationof Box and show how it enables a widerange of useful apps with minimal performance overheadand without sacrificing user privacy.
