Abstract

Unity provides secure and durable storage for personal data that does not depend on the security or availability of a central service. Instead, Unity exploits the trend towards users having more personal computing devices and the increasing amounts of storage available on those devices. This motivates the design of Unity, which does not store data on the cloud provider at all, but instead leverages the availability of the cloud provider to mount a coordination service that enables a user's devices to provide durable storage for the user's data themselves.
