碩士 === 國立清華大學 === 資訊工程學系 === 93 === In order to protect the intellectual property rights of digital content, a DRM system has been developed to prevent illegal behaviors of consumers. People are not willing to accept a new restriction that is insensitive to privacy concerns. So, we propose a new protocol which can provide anonymous buying. Furthermore, we add the anonymous fingerprinting to prevent customers taking advantage of the privacy protection mechanisms to violate the copyright. In the thesis, fingerprinting is customer’s credit card number which is encrypted to become anonymous fingerprinting. When content providers find the illegal video distributing on the internet, they can extract the fingerprinting in the multimedia content and trace the distributors. Our fingerprinting scheme can resist average collusion attack up to 9 colluders.
