Recently, Digital Cinema Initiatives (a joint venture of Disney, Fox, MGM, Paramount, Sony Pictures Entertainment, Universal and Warner Bros. Studios) finally published their Digital Cinema System Specification. In chapter 9, the document includes an 80-page-long specification of the security requirements for digitalized cinemas. There is a lot of the usual DRM parlance in there (including "trusted device lists", device revocation, key management etc.). The chapter also includes an elaborate specification for the use of digital watermarks (called "forensic marking" in the document) as part of the security architecture.
