Abstract

In this paper, a novel visual data hiding method is proposed to conceal a binary visual pattern into a dot diffused halftone image. The visual pattern is revealed by copying the halftone image, shifting the copy and superimposing the shifted copy and original halftone image together. The self-decrypt property of the proposed method make it more robust against geometry distortion, while other existing visual data hiding approaches are not. Experimental results illustrate the advantages and effectiveness of the proposed method as well.

隐藏在点扩散图像中的可视数据
本文提出了一种新的视觉数据隐藏方法,将二值视觉模式隐藏到点扩散半色调图像中。通过复制半色调图像,移动副本,并将移动的副本与原始半色调图像叠加在一起,显示视觉图案。该方法的自解密特性使其对几何变形具有更强的鲁棒性,而现有的可视化数据隐藏方法则没有。实验结果也证明了该方法的优越性和有效性。
