摘要:

当今时代多媒体信息的频繁交换对版权保护提出了越来越高的要求。在这项工作中,我们提出了一种新的音频零水印技术的基础上,图傅立叶变换,以提高版权保护的鲁棒性。在该方法中,使用组合移位算子来构造图形信号,在该图形信号上执行图形傅立叶分析。然后,使用K-means算法将表示音频段的特征的所选择的最大绝对图傅立叶系数编码成特征二进制序列。最后,将生成的特征二值序列与水印二值序列进行异或运算,实现零水印的嵌入。实验结果表明,该方法在抵抗常见攻击和同步攻击方面比现有方法有更好的效果。

英文摘要:

The frequent exchange of multimedia information in the present era projects an increasing demand for copyright protection. In this work, we propose a novel audio zero-watermarking technology based on graph Fourier transform for enhancing the robustness with respect to copyright protection. In this approach, the combined shift operator is used to construct the graph signal, upon which the graph Fourier analysis is performed. The selected maximum absolute graph Fourier coefficients representing the characteristics of the audio segment are then encoded into a feature binary sequence using K-means algorithm. Finally, the resultant feature binary sequence is XOR-ed with the watermark binary sequence to realize the embedding of the zero-watermarking. The experimental studies show that the proposed approach performs more effectively in resisting common or synchronization attacks than the existing state-of-the-art methods.
