                Abstract: 
                Many Content Distribution Protection (CDP) schemes (e.g. Buyer-Seller Watermarking and Asymmetric Fingerprinting) have been proposed to address the problem of illegal distribution of copyrighted content. All of the existing CDP schemes rely on a Trusted Third Party in one way or another to achieve the desired security objectives. In this paper, using the functionalities of Trusted Computing, we present an anonymous CDP watermarking scheme, which minimises the reliance on a Trusted Third Party. Our scheme allows a buyer to anonymously purchase digital content, whilst enabling the content provider to blacklist the buyers that are distributing content illegally.
