一种基于视频压缩的信息隐藏算法实现

Information Hiding Algorithm Based on Video Compression

基于当前流行的视频压缩技术,提出了一种变换域嵌入算法,并通过仿真实验检验了该算法的有效性。该算法以视频图像离散余弦变换(DCT)矩阵的矢量嵌入为基础,以DCT子块为信息嵌入基本载体,将信息隐藏与频域变换相结合,简化了压缩过程的运算量,同时也提高了隐藏的鲁棒性和透明性。

With the concern of prevailing video compression standards, an embedding algorithm in terms of transformed do- main is proposed. The simulation results prove the validity of the algorithm. The algorithm is established on the metric-embedding into the basic message cover of discrete cosine transform microblock, which combines information hiding with frequency transformation. The redundancy of compression computation is reduced. The robustness and invisibility of hiding are improved.
