In (Memon and Wong, 2001), Memon and Wong first proposed a buyer-seller watermarking protocol. Inspired by (Memon and Wong, 2001), Cheung and Curreem recently proposed a buyer-reseller watermarking protocol to address the digital contents redistribution in the second-hand markets over the Internet (Cheung and Curreem, 2002). In this paper, we show that their watermarking protocol is vulnerable to malicious attacks and propose a simple improvement. The main contribution is that we extend their schemes to enable anonymous transactions among a buyer, a reseller, and a seller in order to further protect the privacy of the buyers.
