Laundering and Repackaging of Multimedia Content in Content Distribution Systems

Content distribution systems enable the secure distribution of multimedia content. At the same time, and sometimes more importantly, they should also disable the illegal [re-]distribution of multimedia content. This paper identifies different types of attacks on current systems: laundering attacks and repackaging attacks. The attacks are described generically so that they may apply to most systems used for distributing protected content to set of users. First hints to prevent such attacks are also discussed.
