摘要
针对目前信息隐藏量和鲁棒性之间难以平衡的问题,提出了一种基于DCT域多维格结构的信息隐藏方法,它对诸如MPEG等各种标准编码技术具有很好的鲁棒性.采用矢量变换和格编码来提高性能,每个视频帧里可以存储大量的信息并符合盲检测的要求.实验结果表明,该方法取得了较好的隐藏效果.
Aimed at the difficult balance between the quantity of information hiding and robustness, a new information hiding method based on multidimensional lattices was proposed. The method was of robustness to standard coding techniques such as MPEG. In the vector-based algorithm, using lattice codes for improved performance, large amounts of data was allowed to be stored into each frame of the video sequence. It meets the demand of blind detecting. The experiment results show that the method has better information hiding effect.
