Tutorial on content protection

ABSTRACT

Devising effective Content Protection mechanisms and building satisfactory Digital Rights Management systems have been top priorities for the Publishing and Entertainment Industries in recent years. In this tutorial, we focus on protection tools and standards for entertainment content. We analyze the challenges of content protection systems, ranging from legal aspects and business models to cryptographic techniques. We discuss current technology licensing practices, describe state-of-the-art broadcast encryption mechanisms and forensic approaches, and present content protection standards such as 4C and AACS.
