摘要：

With the increasing preference for information exchange in the form of video, steganography technology based on video will have huge application requirements in military communications, industrial Internet and other fields. High Efficiency Video Coding (HEVC) has received extensive attention for its high compression efficiency since its release in 2013, and after recent years of development, it has been applied to many products, so it is of great significance to research the video steganography algorithm based on the HEVC coding standard. This paper presents a HEVC video steganography method based on intra-frame QDCT coefficient. The secret information is embedded into the coupling coefficient of the selected 8 x 8 luminance QDST blocks to avert the intra-frame distortion drift. And the (7,4) Hamming code is used to reduce the modification of these embedded blocks. The experimental results show that the proposed algorithm can effectively increase the visual quality and get good embedding capacity.
