A Novel Public Key Watermarking Scheme Based on Shuffling

Public key watermarking system is liable to be attacked by seeking to estimate the embedding watermark since there is a public detection key. In this paper, a novel public key watermarking scheme is proposed. Both the user side public watermark and copyright owner´s one are generated from the copyright owner´s private keys, and the watermark detection can be finished either by public watermark or the copyright owner´s private one. Given the public watermark, it is impossible to guess or remove the embedded watermark. Furthermore the detection of the watermark existence can be finished without the original image. Performance of the proposed scheme is studied and the experimental results against removal attack and Jpeg compression show good robustness of proposed scheme.
