针对最新的视频编码标准高效率视频编码（HEVC），提出一种基于帧内模式选择的视频信息隐藏算法。首先，对一幅二值图像进行Arnold 置乱和 turbo 码编码，形成待嵌入的二值信息序列。然后，结合帧内模式选择过程，调制I帧亮度16×16编码单元最优预测模式的奇偶性来实现信息隐藏。由于只在I帧进行信息隐藏，提取时只需部分解码即可提取隐藏信息，无需完全解码与原始视频的参与，实时性较好。实验结果表明：算法对视频质量和比特率的影响较小，且能保证一定的信息隐藏容量，符合视频隐藏算法的基本要求。

This paper proposed an information hidden algorithm which was based on high efficiency video coding (HEVC)intra-prediction modes.Firstly,this algorithm uses Arnold transform and turbo coding method to get a binary information sequence to be embedded.Then,combine with the process of intra frame mode selection,we hide information by modulating the best prediction modes′parity of I frame luminance block′s coding units.Since the hidden information only be embedded in I frame,during the extraction,only partial decode the steam is needed,we don′t need decode the steam completely and don′t need original video either.Besides,the real-time performance is good.Experimental results show this algorithm only has a little influence on video quality and bit rate and also can ensure a considerable information hiding capacity.Therefore,it is conform to the basic requirements of video hiding algorithm.
