有的話，最好在未來三天內(nèi)，急用，如果好的話還可追加懸賞，謝謝！
Abstract Raw audios contain significant amount of redundancy which can be used for steganographic purposes. But practically most audios are stored and transmitted in the compressed formats. In this paper, we present a MPEG-1 Layer III (MP3) audio CODEC based steganographic method to embed secret message during encoding. The Huffman tables in MP3 standard are first partitioned into three groups. The secret message is then embedded by Huffman table swapping strategy. Instead of fully decoding the stego-audio, the extraction of the secret message can be done just by parsing the side information. The proposed method is designed under the restrictions of the MP3 compression standard without any modifications or additions to the existing standard. Experimental results show 來加個(gè)親+++

這是一個(gè)在通用的MP3音頻文件中隱寫的軟件。在把WMA壓縮轉(zhuǎn)換成MP3的過程中，對要隱藏的文本txt文件進(jìn)行加密并寫入MP3。 使用方法很簡單，例如，要隱藏的TXT文件是aa.txt, 要壓縮的WMA文件是bb.
