Abstract
Abstract There are many of research have been proposed for embedding information into digital video. However, most of those schemes extending information hiding technique for still image to video by treating each single frame as a still image and embed data in intra-frame. In this paper, we propose an effective information-hiding scheme for digital video. This scheme embeds information in digital video using the phase angle of the motion vector of the macroblock in the inter-frame. We can apply this scheme to either compressed or uncompressed videos. Furthermore, the embedded information can extracted directly without using the original video sequences. Our experimental results prove the feasibility of the proposed methods. Comparing with the other literature, our method has better performance.
