A Novel Information Hiding Algorithm Based on Grey Relational Analysis for H.264/AVC

On the basis of analyzing some existing video steganographic algorithms and find out some problems, like have large impact on the video quality and bit rate, so we propose a new algorithm based on grey relational analysis combining with the partition modes features of the H.264/AVC. The algorithm firstly compute the grey relevancy of blocks and judge if it has texture features. Then perform DCT on the current frame. Finally choose the proper capacity based on partition modes and embed information in DCT numbers. The experimental results show that the proposed algorithm has little impact on the video quality and bit rate, also has the advantages that anti-noise, anti-filter and high capacity information hiding.
