Abstract-This paper deals with the problem of continuous usage control of multiple copies of data objects in distributed systems. This work defines an architecture, a set of workflows, a set of policies and an implementation for the distributed enforcement. The policies, besides including access and usage rules, also specify the parties that will be involved in the decision process. Indeed, the enforcement requires collaboration of several entities because the access decision might be evaluated on one site, enforced on another, and the attributes needed for the policy evaluation might be stored in many distributed locations.
The work in REF , instead, addresses the problem of continuous Usage Control when multiple copies of a data object are stored in distributed systems, such as the Cloud.
