According to H.264 video encoding standard, a fragile video watermark algorithm based on motion vector and mode selection is proposed. By selecting the motion vector with small splitting and minimizing the Laragian function in motion search to embed the fragile watermark into the motion vector that have the best rate distortion capability. Experimental results show that the proposed algorithm can achieve better sensitivity to the re-encoding processing and bring little influence to video quality and bit rate.
