Abstract

The aim of this paper is to propose a digital watermarking scheme, which employs visual cryptographic method to enhance the security without decreasing the data payload. A binary image, called watermark, is split into two shares. Then, one of the shares is embedded into the host image, and the other is held by the owner. When proving the ownership, the owner has to extract the embedded share and recover the watermark with his/her own share. The experimental results show that our scheme can resist most of common attacks.
