Digital watermarking is the technique which embeds an invisible signal including owner identification and copy control information into multimedia data such as image, audio and video for copyright protection. A blind robust algorithm of hiding data into H.264 video stream rapidly was proposed in this paper, copyright protection can be achieved by embedding the robust watermark during the procedure of intra prediction encoding which is characteristic of H.264 standard. This scheme is well compatible with H.264 video coding standard and can directly extract the embedded data from the watermarked H.264 compression video stream without using the original video. Experimental results demonstrate that this scheme is very computational efficient during watermark embedding and extraction and the embedded data not lead to increasing the bit-rate of H.264 bit-stream too many. This algorithm is feasible for real time system implementation.
