3D H.264视频正在成为全球主流大众媒体，以它为载体的隐秘通信是未来世界信息战、网络战的特别战场。目前相关研究大多集中在数字水印和非3D H.264视频隐写领域。本项目以3D H.264视频隐写术为研究对象，旨在探索适应3D视频的，兼具安全性、鲁棒性和可逆性的隐写算法，整体加强隐写的前安全性和后安全性，提高其抗隐写分析的能力。拟基于预研成果，探索用本团队创新性提出的帧内无失真漂移3D 视频隐写，基于纠错码和秘密共享的分层加固鲁棒视频隐写，以及基于位图或K平移的可逆视频隐写等算法和方法，解决3D H.264视频隐写的帧内漂移阻断、多纠错联合预编、以及中高频区可逆嵌匿等三个方面的关键科学问题。研究成果可为3D H.264视频隐写及隐写分析提供理论依据和技术方法，并直接指导构建3D H.264视频隐秘通信平台，强力支持我国在军事、外交和重要商务领域的特殊应用，服务国家网络空间安全战略。

3D H.264 video will be the main mass media in the future. The secret communication based on 3D H.264 video will be a special battlefield for the world's information warfare and network warfare. The current research is mostly concentrated in the field of digital watermarking and steganography without 3D H.264 video. The project will study the steganography for 3D H.264 video, aiming at designing some secure, robust and reversible steganography algorithm adapted to 3D video, attempting to strengthen the fore security, after security, and the ability to resist steganalysis. Based on preliminary research results, we intend to explore 3D video steganography algorithm without intra-frame distortion drift, robust video steganography algorithm with hierarchical reinforcement based on error-correcting codes and secret sharing, and reversible video steganography algorithms using bitmap or K-shift and the like. We will use these theories and methods to solve three key scientific issues of the 3D H.264 video steganography such as cutting the intra-frame distortion drift, the joint preprogram with some error correcting methods and reversible embedding in middle or high frequency areas. The research can provide the theoretical basis and technical methods for steganography and steganalysis based on 3D H.264 video, and direct guidance to build the covert communications platform for 3D H.264 video, strong support to our military, diplomatic and special applications of significant business areas, and service to the security strategy of the national cyberspace.
