基于Huffman编码的大容量MP3隐写算法
A high capacity MP3 steganography based on Huffman coding
摘要
Abstract
A high capacity steganography method for mp3 audios is proposed in this paper. According to the characteristic of Huffman coding, the code words in Huffman tables are first classified to ensure that the embedding operation does not change the bitstream structure in MP3 standard. Then secret data are embedded by replacing the corresponding code words. The embedding strategy is based on multiple-base nation system. The structure of bit stream and the size of the cover audio can be kept unchanged after embedding. The results show that the proposed method can obtain higher hiding capacity and better effi ciency than that of the method under binary case. Furthermore, the imperceptibility can also be better maintained in our method.关键词
