摘要 扰动调制是一种非线性水印技术,已应用于数字图像。本文结合听觉特性,利用这一技术将水印信号嵌入在数字音频频域中。实验表明水印的嵌入不会被人耳觉察,并且该方案在抵抗各种常见的攻击方面表现出良好的稳健性。 As a nonlinear method, dither modulation has been applied to spatial domain watermarking embedding into still images. In this paper, a novel audio watermarking scheme using dither modulation in the frequency domain is described. The proposed approach makes use of the human auditory system (HAS) characteristics. Simulation results show that the embedded watermark is highly imperceptible with sufficient robustness against various common attacks.
