A robust asymmetric watermarking scheme using multiple public watermarks

In recently proposed asymmetric watermarking schemes, the public detection is less robust than the private detection. To resolve this problem, a robust asymmetric watermarking scheme using the multiple detection watermarks for public detection is proposed in this letter. In this scheme, the private watermark used for embedding is constructed by secretly selecting the partial elements of those public watermarks. It provides the same robustness for the public and the private detections, and the robustness is demonstrated in the computer simulations.
