Towards a Policy Enforcement Infrastructure for Distributed Usage Control

摘要

Distributed usage control is concerned with how data may or may not be used after initial access to it has been granted and is therefore particularly important; in distributed system environments. We present an application- and application-protocol-independent infrastructure that allows for the enforcement of usage control policies in a distributed environment. We instantiate the infrastructure for transferring files using FTP and for a scenario where smart meters are connected to a Facebook application.
