Many frame by frame video watermarking methods where proposed, but only a few of them are robust against collusion attacks. These attacks can be easily conducted and their result is an unmarked video. In this paper a frame by frame watermarking method is proposed, which is robust against unintentional attacks, attacks of frame dropping, frame swapping and collusion attacks. Experimental results are also included to verify the robustness of the proposed method against some of the above mentioned attacks.
This paper describes a new method for video watermark embedding, using the knowledges already available from watermark embedding into digital static pictures. The watermark is embedded in transformed domain using Discrete Wavelet Transform (DWT). This paper also describes experiments conducted on the proposed watermark embedding method. The goal of these experiments was the test the robustness of the method presented in the paper against several watermarking attacks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
