Abstract: In order to solve the problems of security and capacity of confidential information during public network transmission, an information hiding algorithm based on the High Efficiency Video Coding (HEVC) background was proposed. The background image of multi-view images in HEVC was used as the carrier. Firstly, the background image was decomposed into three gray-scale components by using lαβ color space theory. Then, the image components such as α and β were transformed by Discrete Cosine Transform (DCT) method. Finally, the confidential information was embedded into the region of carrier repeatedly. With relative low energy weight, the mid-frequency coefficient regions of α and β components after DCT were both chosen as the hidden regions to be embedded repeatedly with the confidential information, which makes the proposed algorithm have good invisibility and robustness. The experimental results show that, compared with the algorithms based on intra-frame and inter-frame, the invisibility of the proposed algorithm was improved respectively by about 16.1% and 11.4% while the robustness of the proposed algorithm was increased respectively by about 55.5% and 20.2%.

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αβ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αβ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%。
