| 摘 要： | 针对在传输语音秘密信息过程中存在破坏或窃取的问题,本文提出一种鲁棒性较强的信息隐藏方法.把一段语言作为秘密信息隐藏到宿主音频中,在公共信道中传递秘密信息.该算法根据人类听觉系统,在小波域中嵌入秘密信息.并且利用MH公钥结合汉明码,不但使隐藏的信息具有加密功能,而且在提取时具有纠错功能.对于外界的噪声、压缩、滤波干扰有很强的抗干扰能力.

| Abstract: | Secret audio message has to experience all kinds of attacks during transporting.The paper presents a steganography algorithm with strong robustness.It embeds a speech as the secret message into original audio signal,and transmits the secret message in the public channel.The algorithm makes use of Human Auditory System(HAS) characteristics and embeds secret message in the wavelet domain.Combing MH public key and hamming coding,the algorithm not only encrypts the hiding information but also corrects the error... |
