基于混沌的视频信息隐藏技术算法

Algorithm for Video Information Hiding Based on Chaos

基于混沌的视频信息隐藏算法,利用混沌序列的类随机性对嵌入信息进行置乱,以提高保密性。即利用混沌序列的自相关和互相关特性实现信息的嵌入和盲提取。同时算法与视频压缩算法相结合,在DCT域的次低频系数中嵌入信息,提高其鲁棒性。

The video information hiding algorithm based on chaos uses the analogy randomicity of chaos sequence to disturb the hiding information, which improves the secrecy. The algorithm also uses the characteristic of autocorrelation and cross-correlation of chaos sequence to embed information and extract it blindly. At the same time, the algorithm is combined with the video compressing standards, and embeds the information in the coefficient of the sub-low frequency in DCT domain, which improves the robustness.
