A blind high definition videowatermarking scheme robust to geometric and temporal synchronization attacks

Due to the availability of high speed online streaming sites, a pirated copy of a digital video can be easily distributed to a global audience. This paper proposes a digital video watermarking technique based on the dual-tree complex wavelet transform that can protect this pirated digital video content. In this scheme, the watermark is embedded into the chrominance channel of the video frames to provide a high quality watermarked video. The watermark is detectable without reference video content as well as the original watermark which makes this method robust to temporal synchronization attacks such as frame dropping and frame rate conversion. The proposed method is also robust to geometric attacks such as arbitrary downscaling in resolution, rotation, upscaling, and cropping.
