A novel blind video watermarking scheme offering a low computational complexity is presented in which the computer generated holograms are used as the watermarks. In the scheme, the original video is divided into nonoverlapping groups of pictures (GOPs). A quantization method is used to insert the mark hologram into the low frequency wavelet coefficients of every GOP. The extraction procedure does not need the original video. Experimental results demonstrate that the presented scheme is transparent and robust to a variety of attacks, including compression, noise addition, filtering, occlusion, cropping and temporal attacks, etc. One of the most important advantages of the suggested method is its simplicity and practicality.
