This paper presents a novel Energy-Based Watermarking scheme (EBW). The aim of EBW is to make the watermark survive video compression and collusion. After carefully analyzing the effect of the video compression on different type regions of video, two properties of the video coding are explored. According to these two properties, the watermark is deliberately embedded into the video to improve the robustness against video compression. At the same time, an improved fingerprint identification method is contained in EBW to help resist collusion attacks. The experimental results demonstrate the validity of EBW.
