Secure Public Digital Watermarking Detection Scheme

One of the threats to watermarking security is unauthorized removal. In this paper, a framework based on extended Trusted Computer Platform to solve this problem was presented. Using Trusted Computing Platform could enhance the security of watermarking detection. The TPM as a supervisor that control the watermark detection program and only the legal one can use the secret knowledge, that is, this secret knowledge bind with detection program in crypto format. This can ensure the whole scheme is secure although detection program is public. The security and feasibility about the framework was discussed, especially the resistant to Oracle attack. Finally, it can be conclusion that a traditional watermarking scheme could get the capability of secure public detection after being transformed based on this framework.
