A Language for Provenance Access Control *

摘要

Provenance is a directed acyclic graph that explains how a resource came to be in its current form. Traditional access control does not support provenance graphs. We cannot achieve all the benefits of access control if the relationships between the data and their sources are not protected. In this paper, we propose a language that complements and extends existing access control languages to support provenance. This language also provides access to data based on integrity criteria. We have also built a prototype to show that this language can be implemented effectively using Semantic Web technologies.
