Research on Information Hiding     

Xiuhui Ge Renpu Jiao Hao Tian Jiazhen Wang 《美中教育评论》2006,3(5):77-81

With the development of information technology, people have paid more and more attention on the information security today. Information hiding research has become the focus of the information security research. Because every Web sites and network communication depend on the multimedia, such as audio, video, image and so on. Information hiding technology can embed secret information into a digital media source without impairing the perceptual quality of that source. Other people can＇t feel this secret information. So the secret key, the signature or the private data can transform securely in the Internet. In this paper, we mainly introduce the improving action of steganography and provide the application of the steganography in information technology.  相似文献   

能抵抗RQP分析的密写技术   总被引：6，自引：0，他引：6  

王朔中  张新鹏  张开文 《上海大学学报(英文版)》2002,6(4):273-277

A new steganographic approach for 24-bit color images that can resist the RQP(raw-quick-pairs)steganalysis is described.The technique is based on modification of color triplets such that the existing color palette is not excessively expanded or even reduced.In this way,numbers of unique colors and pairs of close-colors in the image do not rise significantly.This invalidates the RQP analysis.Experimental results are presented to support the argument.  相似文献   

3组隐写特征的互补性分析及其 面向空域隐写的融合     

张弢  赵险峰  黄炜  盛任农 《中国科学院大学学报》2012,(2):264-270

针对空间域隐写,分析了小波特征函数统计矩、高阶统计特征和差值像素邻接矩阵3组重要隐写特征间的互补性,利用基于互信息准则和增强特征选择的方法进行特征融合. 分析和实验表明,3组特征间存在互补性,融合后能够得到更好的正确率.  相似文献   

视频隐藏信息检测技术研究     

金小华 《苏州市职业大学学报》2010,21(3):30-34

信息隐藏技术可以使机密资料通过普通的文本、图像、音频、视频等载体轻易越过防火墙系统．因此检测网络上传输的文件是否含有隐藏的信息对于维护网络的安全,防止不法分子利用网络泄密,对于维护国家安全有着非常重要的意义．着重对利用视频文件进行隐藏信息传输的检测算法进行了研究,并给出了视频文件隐藏信息检测系统设计方案．  相似文献
