In recent years video watermarking has become an important research issue due to increase in threats of video piracy, content authentication, and ownership integrity. In this paper, we propose a robust watermarking method with the blind extraction process for compressed video streams like H.264/AVC. The method embeds invisible watermark bits into the P-frames. Appropriate block selection and the embedding algorithm restrict the increase in video bit rate. The security of the method lies in selecting candidate blocks using a pseudo random key from set of previously selected blocks. The simulation results show that the proposed method is robust against common image and video watermarking attacks. A robust watermark is generated in order to withstand frame drop and insert attacks, which increases the overall robustness of the proposed method.
