    摘要:

    屏摄信道传输中的多媒体安全问题是数字水印研究领域中的一大难点。鉴于屏摄过程中存在光照度差异和采样失真的问题,基于数字信道设计的水印方法并不适用于屏摄信道,为此,提出了一种基于可逆神经网络的小波域抗屏摄水印方法,以解决“跨媒介鲁棒性”问题。通过基于U-Net网络结构的预处理网络对水印信息和原始图像进行预编码生成残差图像,将该残差图像与原始图像进行离散小波变换,并利用可逆神经网络实现在小波域的水印嵌入和提取。在模型训练过程中加入噪声池,以提升抵抗屏摄噪声攻击的鲁棒性。实验结果表明,通过所提方法生成的含水印图像具有更好的视觉质量,且在不同距离、角度和光照度的屏摄情况下,均有着较高的水印信息提取准确率。

    Abstract:

    Multimedia security in screen-shooting channel transmission remains a major challenge in the digital watermarking research. In view of the problems of differences in light intensities and sampling distortions during the screen-shooting process, watermarking schemes designed based on digital channels are not suitable for screen-shooting channels. Therefore, a screen-shooting resilient watermarking scheme based on invertible neural networks in the wavelet domain was proposed to address the issue of "cross-media robustness". First, the watermark message and the original image were preprocessed using a preprocessing network based on the U-Net structure to generate the residual image. Next, the residual image was subjected to discrete wavelet transform with the original image, and the invertible neural network was used to embed and extract watermarks in the wavelet domain. Finally, a noise pool was integrated into the model training process to enhance the robustness against screen-shooting noise attacks. Simulation results demonstrate that the proposed scheme generates watermarked images with better visual quality and achieves high accuracy of watermark extraction at different distances, angles, and light intensities of screen-shooting.
