摘要
FLV格式视频是当今互联网上最为流行的流媒体文件格式,兼容多种视频编码格式并对其封装,针对这种网络FLV格式视频的认证技术,信息隐藏技术应运而生,设计和实现高安全性与强鲁棒性的视频隐蔽通信系统,保证特殊环境下秘密信息的隐蔽传递,是一项崭新而有意义的研究。因而解析了FLV格式的网络视频文件,研究其作为隐蔽通信载体的可能性和技术难点,并提出了一种基于H.264编码的能够抵抗如新浪播客网站各种处理操作的鲁棒视频隐写算法,构建了一个完整的网络视频隐蔽通信系统。
Recently,FLV file has become the most popular video format in video-hosting websites,and it is compatible with many video coding and encapsulates them.Aiming to it,video authentication technique and information hiding technique develop quickly,therefore,it is an innovative research to design and achieve high-security and strong-robustness video hiding communication system based on FLV in some special environments.In this paper,FLV video file is analyzed in detail,the possibility and technique difficulty as a cover file in steganography is deliberated.Moreover,a video steganography algorithm based on H.264 coding is designed.Experimental results show that it is robust to processing from websites like v.sina.com.Finally,a complete website video hiding communication system is constructed.
