In the paper, we propose a system that uses H.264 video compressed and semi-fragile video watermarking to reach video recording automatically. In recent years, H.264 is a new advanced video compressed standard. It provides high compression efficiency and compress quality, compress the standard for the video compressed of new generation. Digital data is easy(More)
