Abstract: In this paper, an improved information hiding method for H.264/AVC which embeds information by changing the value of the intra 4×4 prediction mode is presented. In this method, information is embedded into 4×4 macroblocks in H.264/AVC intra prediction. However, the change of encoding cost by embedding information causes the decrease of 4×4 macroblocks. The improved method considers the change of encoding cost in selecting intra prediction size and increases the amount of information allowed to be embedded by 20-50 percent compared with the conventional method.
