英文摘要： 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 g
