【摘要】：针对秘密信息在公开网络传输的安全性和容量性问题,提出了一种基于高效率视频编码(HEVC)背景的信息隐藏算法。利用HEVC中多视点图像的背景图作为载体,首先对其进行lαβ分解得到三个灰度分量子图,然后选取α和β分量子图作离散余弦变换,最后将秘密信息重复嵌入到载体区域中。隐藏区域选取能量权重较低的α及β分量子图的离散余弦变换中频系数区域,且进行重复嵌入,使得算法具有良好的不可见性和鲁棒性。实验结果表明,所提算法比基于帧间和帧内算法不可见性分别提高16.1%和11.4%,鲁棒性分别提高55.5%和20.2%。
[Abstract]:In order to solve the problem of security and capacity of secret information transmission in public network, an information hiding algorithm based on (HEVC) background of high efficiency video coding is proposed. Using the background map of multi-view image in HEVC as the carrier, three gray component subgraphs are obtained by l 伪尾 decomposition, then the 伪 and 尾 sub-quantum graphs are selected as discrete cosine transform, and finally the secret information is repeatedly embedded into the carrier region. The hidden region selects the discrete cosine transform intermediate frequency coefficient region of 伪 and 尾 component subgraphs with low energy weight, and repeatedly embeds it, which makes the algorithm have good invisibility and robustness. The experimental results show that the invisibility of the proposed algorithm is 16.1% and 11.4% higher than that of the intra-frame algorithm, and the robustness of the proposed algorithm is improved by 55.5% and 20.2%, respectively.
