摘要

提出了一种在灰度图像的视觉秘密共享中隐藏两个水印的方案。在秘密图像半色调过程中嵌入一个水印，在半色调图像加密过程中隐藏另一个水印。采用非扩展的视觉秘密共享模型对半色调图像进行加密。在数据提取中，只需要进行异或操作。实验结果表明了该方案的有效性。

Joint Multiple Watermarking and Non-Expansion Visual Cryptography

This paper proposes a scheme to hide two watermarks in visual secret sharing of a gray level image. One watermark is embedded during secret image halftoning, and the other watermark is hidden during the halftone image encryption. A non-expansion visual secret sharing model is used to encrypt the halftone image. In data extraction, only exclusive-OR operation is needed. Experimental results show the effectiveness of our scheme.
