Multimedia content delivery to capable smart phones with high-speed next-generation Internet connectivity is becoming commonplace. However, the openness of delivery demands adaptive and robust management of intellectual property rights. The purpose of this article is to describe a framework to address the central issues in content delivery: a scalable peer-to-peer-based content delivery model. Our method pairs the delivery with a secure access control model that enables data providers to secure a return from making their original content available. Our work resulted in a prototype implementation written in Java that includes a client for the Android mobile platform. Adding robust trust management to scalable peer-to-peer content delivery is the major significance of our work.
