• The communication has become faster and easier through the Internet. The creation and delivery of various data (video, images, speech and audio) have grown by many fold. However, the processing of these data in the digital domain raises the issues like the content protection and providing the ownership of original content. Digital watermarking is a very useful technique which can overcome the shortcomings of current copyright laws of the digital data. Video is one of the most popular multimedia objects. Video watermarking is used to embed the ownership logo into the digital video content for the protection. The proposed algorithm uses energy compression property of DCT and multiresolution of DWT. The Arnold transformation technique is applied, which enhances the security level and also increases the robustness. Experiment results show that the proposed algorithm has the larger embedding capacity and the excellent robustness against all the attacks.
