A publicly verifiable lossless watermarking scheme for copyright protection and ownership assertion
چکیده انگلیسی

In this paper, a discrete cosine transform based copyright protection scheme that does not require the original image for logo verification is proposed. Features of logistic map and discrete cosine transform are used to generate the verification map. Digital signature and timestamp are used to make copyright proving publicly verifiable. We have combined cryptographic tools and digital watermarking, in order to enhance the security and reliability of copyright protection. In addition, chaotic map is used to generate a chaotic pattern image, which can be used as secret key to improve the security of proposed algorithm. Experiments are conducted to show the robustness and effectiveness of the proposed algorithm. Experimental results show that our scheme outperforms related works in most of the cases.
