Abstract: The present invention disclosed a 3D-HEVC depth video information hiding method based on single-depth intra mode, which comprises information embedment part and information extraction part. During information embedment, if the pixels in the candidate list are equal using the encrypt information to modulate the index of the pixel and completes the embedment. If the pixels are different, judging the neighboring CU of the CU whose depth is 2 or 3 and modulating the index of the pixel to complete embedment of the hidden information. The advantage of the present invention is high security, low calculation complexity and small influence on data rate.

Abstract translation: 本发明公开了一种基于单深度模式的3D-HEVC深度视频信息隐藏方法，包括信息嵌入部分和信息提取部分。 在信息嵌入期间，如果候选列表中的像素相等，则使用加密信息来调制像素的索引并完成嵌入。 如果像素不同，则判断深度为2或3的CU的相邻CU，并调制像素的索引以完成隐藏信息的嵌入。 本发明的优点是安全性高，计算复杂度低，对数据速率影响小。
