Abstract:传统扩频信息隐藏技术存在着安全隐患,非法接收者在不知道扩频序列的情况下,可以盲检测出隐藏的秘密信息.本文提出伪随机码掩蔽的扩频信息隐藏方法,用伪随机码来混淆嵌入的信息,抵抗隐藏信息非法提取操作.为了进一步改善隐藏信息的合法提取,文中对扩频序列进行了优化,在一定载体失真度的限制下,设计了最优扩频序列使最优线性滤波器的输出端得到最大的信干噪比.实验结果证明了文中所设计的伪随机码掩蔽的最佳扩频信息隐藏方法可以使现有的盲检测攻击的误码率高达到0.5,将秘密信息被非法接收者截获的概率降到最低.
I am not a star professor, but I am working on the road to a star professor of tomorrow. For this reason, self-motivated graduate students are desired to my research group. Self-motivated attitude and initiative are the most important characteristics in our laboratory. Students with preliminary knowledge on signal (image/video) processing and programming skills are most welcome. For your academic trip in my group, I will devote myself to training your FIVE abilities: Intellectual skills, Communication skills, Personality characteristics, Habit of work, Mechanical skills, which are considered as the most important abilities of a graduated student.
