Abstract :
In this paper, we propose a new digital watermarking algorithm of color image. We process the watermark to generate two shares based on visual cryptography. And one of the shares is embedded into a color image and another is protected by the copyright. The scheme is easy to implement and highly feasible. In addition, the embedding capacity of watermarks and robustness are improved to effectively.
