摘要
信息隐藏技术作为一种重要的信息安全手段,它在视频图象序列中的应用越来越受到人们的重视。文章介绍了应用于MPEG2编码视频图象序列的信息隐藏技术,分析了这些技术的基本方法与性能,最后对视频图象中信息隐藏技术的进一步研究方向进行了展望。
As an important means of the information security, steganography' s application in video image sequences draws much attention to more and more people. The paper presents some information hiding technology which is used in the video image sequences coded with MPEG2 standard, and analyses their basic methods and performance. Finally, the paper looks forward to the future research direction of steganography in the video image sequences.
