无帧内失真漂移的H.265视频鲁棒隐写方法研究

H.265(HEVC)视频编码标准正成为全球主流大众媒体的标准，以它为载体的隐蔽通信必定是未来信息安全的主要手段。本项目拟基于H.265视频编码标准这一课题，探索H.265视频隐写技术，提升H.265视频隐写鲁棒性，实现基于H.265视频鲁棒隐写方法。首先，针对H.265视频编解码的数据特征，设计基于H.265的无帧内失真漂移视频隐写算法。然后，针对隐藏了秘密信息的H.265视频在传输过程中遭到有意或无意的攻击而产生的丢包、帧错或比特错等引起的秘密信息无法恢复等问题，设计出基于BCH码、多秘密共享及秘密共享等的视频鲁棒隐写方案；针对不能容忍永久失真的H.265视频载体,设计能完全恢复原视频载体的H.265鲁棒可逆隐写方案。最后，构建H.265视频隐蔽通信平台。研究成果可为H.265视频隐写及隐写分析提供理论与技术支持，服务我国的军事、外交和商务等信息安全领域，进一步助力提升国家信息安全。

Considering the H.265 (HEVC) video coding standard is becoming the one of the mainstream mass media, video steganography based on H.265 must be a future main means in the field of information security. For this topic this project aims to explore new video steganography technology of H.265 video standard, to enhance the robustness of video steganography, and to achieve robust video steganography of H.265 standard. Firstly, according to the characteristics of H.265 video coding and decoding, we design a video steganography algorithm of H.265 without intra frame distortion drift. Secondly, according to the packet loss, frame error, bit error, etc., which can cause secret information not to be recovered, we design a robust video steganography algorithm based on BCH code, multi secret sharing and secret sharing. Finally, we construct the platform of video steganography based on H.265 standard . The research results can provide theoretical and technical supports to H.265 video steganography, serve military, diplomatic and commercial special fields, and further promote the national information security.
