| 摘 要： | 针对MP3音频的编码特点,提出了基于Huffman码字替换原理的音频隐写算法。与以往的MP3隐写算法相比,该算法直接在MP3帧数据流中的Huffman码字上嵌入隐蔽信息,不需要局部解码,具有透明度高、嵌入量大、计算量小的特点。通过实验分析了算法的透明性、嵌入量、码字的统计特性等方面的特点。

| Abstract: | A MP3 Steganography algorithm is introduced based on replacing Huffman codes with the characters of MP3 coding.Compared with ancient steganography algorithms,the algorithm directly embeds secret information in Huffman codes of MP3 frames,and it need not partly decode.It has the characters of transparency,big capacity and low computing complexity.Experiments analyze the characters of the algorithm. |
