Abstract

Traditionally, the process of online digital content distribution has involved a limited number of centralised distributors selling protected contents and licenses authorising the use of these contents, to consumers. In this paper, we extend this model by introducing a security scheme that enables DRM preserving digital content redistribution. Essentially consumers can not only buy the rights to use digital content but also the rights to redistribute it to other consumers in a DRM controlled fashion. We examine the threats associated with such a redistribution model and explain how our scheme addresses them.
