Protecting copyrights of digital contents achieves much attention with rapid growth of electronic commerce in the Internet. There are some well-known methods such as watermarking and obfuscation. Recently, Yi and Willy introduced a new solution for DC distribution using restrictive partially blind signatures. In this paper, we follow this paradigm to propose a new Digital Copyright (DC) distribution scheme to ensure the robustness of DC distribution using Chen et al's new restrictive partially blind signature scheme. Moreover, we prove that our scheme can achieve the desired security notions. © 2008 Binary Information Press.
