Description: MP3音频流数字水印方案，试验表明该方案能得到较高的嵌入容量，对原始音频信号的改变较小，具有较好的隐形性，完整水印提取时间短，可以在音频播放过程中同步完成。通过对算法的进一步研究，我们发现可以利用插件技术将算法嵌入了当前的主流播放器中，从而实现水印信息的实时嵌入和提取。这可能成为保护网络音频版权、网络秘密通讯的一种可行的、低成本的解决方案。
-MP3 audio streaming digital watermarking program, experiments show that the program can be embedded in a higher capacity, the original audio signal changes in smaller, has better stealth, and integrity of the watermark extraction time is short, you can sync audio player to complete the process. Algorithm by further studies, we found that plug-in technology can make use of the algorithm embedded in the mainstream of the current players in order to achieve real-time information watermark embedding and extraction. This may be the protection of network audio copyright, secret communications networks as a viable, low-cost solution. Platform: |

Description: MP3Stego will hide information in MP3 files during the compression process. The
data is first compressed, encrypted and then data hidden in the MP3 bit stream.
Although MP3Stego has been written with steganographic applications in mind it
might be used as a watermarking system for MP3 files. Any opponent can
uncompress the bit stream and recompress it this will delete the hidden
information -- actually this is the only attack we know yet -- but at the
expense of severe quality loss.-MP3Stego will hide information in MP3 files during the compression process. The

Description: All three, Discrete Wavelet Transform (DWT) - Singular
Value Decomposition (SVD) and Adaptive Tabu Search
(ATS) have been used as mathematical tools for embedding
data into an audio signal. In this paper, we present a new
robust audio watermarking scheme based on DWT-SVD and
ATS. After applying the DWT to the cover audio signal, we
map the DWT coefficients, and apply the SVD, we search for
the optimal intensity of audio watermarking by using the
ATS. Experimental results show that the watermarking
method performs well in both security and robustness to
many digital signals processing, such as filtering,
cropping, mp3 and random noise. Platform: |

Description: ：针对MP3 编码方式和帧结构进行分析，利用帧中的比例因子提出了一种压缩域水印算法。算法通过引入帧变化分析步
骤，很好地实现了水印的自适应嵌入。对于不同的系统要求，还可以通过修改门限信噪比的值SNRlim按需进行水印嵌入，使算法
具有更大灵活性。同时在牺牲一定的嵌入空间前提下，实现了水印信息的自同步。实验表明，对于不同风格的音乐，该水印算法
具有很好的不可听性。-In this paper，the encoding method and the frame structure of MP3 are expounded in detail，a watermark algorithm
is proposed based on the scale factor in MP3 frame.By introducing the step of frame altering analysis，the algorithm
can realize that watermarks is embedded adaptively.By modifying threshold SNRlim（the ratio of signal to noise），the algorithm
can meet different requirements of some system，that is what enable the algorithm to have a bigger flexibility.Based on expense
of some embedding positions，the watermark can be embedded with self-synchronization.The experiment results show
this algorithm can get a good audio effect with various types of audio. Platform: |
