Contents Distribution, DRM, copyright, security


The widespread use of the Internet brings about issues regarding intellectual property and copyright. After content is downloaded, no further protection is provided on the content that has been accessed. DRM (Digital Rights Management) technologies came out to ensure the protection of copyrighted information. In this paper, we propose architecture for secure distribution architecture for copyright-protected digital contents. Distinguishing features of our proposal are the transparency of contents distribution and the level of security the distribution service offers. Transparency of contents distribution is based on our business model, modified version of IMPRIMATUR model. Secure contents distribution is achieved through the use of distributed contents keys scheme, which ensures that only authorized entities can access the copyright-protected contents.
