A novel asymmetric watermarking scheme

In this paper, a novel asymmetric watermarking system is proposed, which is robust against the inserter attacks. The user´s side watermark is generated from the copyright owner´s one and the watermark detection can be finished either by user´s side watermark or the copyright owner´s one, and they are reciprocal to each other, which makes our scheme capable of resisting the inserter´s attacks. Furthermore, the detection of the watermark existence is in no need of the original properties. The experimental results against inserter attack show good robustness of our schemes.
