Joint Multiple Watermarking and Non-Expansion Visual Cryptography

摘要：

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.
