The MP3 Steganography Algorithm Based on Huffman Coding

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.
