There are many researches that have been proposed for embedding data into digital video. However, most of those schemes extending data hiding technique for still images to videos by treating each single frame as a still image and embed data in intra-frame. In this paper, we propose an effective data-hiding scheme that embeds data in digital videos using the phase angle of the motion vector of the macro block in the inter-frame. We overview lossy video compression to define our notation and evaluation metrics.. The video is ordered into groups of pictures (GOPs) whose frames can be encoded in the sequence. The temporal redundancy between frames is exploited using block-based motion estimation that is applied on macroblocks of size in or and searched in target frames. Furthermore, the embedded data can be extracted directly without using the original video sequences. Our experimental results prove the feasibility of the proposed method. The evaluation is based on two criteria: minimum distortion to the reconstructed video and minimum overhead on the compressed video size
