The Internet has enabled sharing of data on an unprecedented scale. Data of all forms and shapes is becoming easily accessible. Peer-to-peer content delivery approaches enable massive scale in the amount of data volume that can be efficiently delivered. The openness of delivery demands adaptive and robust management of intellectual property rights. In this paper we propose a framework to address the central issues in content delivery: a scalable peer-to-peer-based content delivery model, paired with an access control model that balances trust in end users with a risk analysis to the data provider. Our framework will enable data providers to extract the maximum amount of return, i.e. value, from making their original content available. We provide a tool to leverage the greatest amount of reward from the intellectual property that is released to the Internet.

One of the main approaches to accessing heterogeneous data is via the use of a mediation framework. The current problem with mediation systems is that they are viewed as black boxes from the perspective of their clients. As clients enter their data, they are unable to control the access to their data from entities within the mediation system. In this paper we present a solution in the form of a security framework, named Collaboration Security Framework that addresses the needs of all entities, i.e. external clients, mediators or data sources, to have autonomy in applying security policies during collaboration. As a result all entities participating in a collaboration have control over the access to their data by applying local, global and collaboration channel security rules, which can be changed at runtime and that are security model independent.
