The Image Watermarking Technique Using Visual Secret Sharing Strategy

Watermarking techniques are primarily used to hide information and for copyright protection. In this paper, we propose a digital watermarking scheme, which is based on visual cryptography and image processing techniques. One advantage of visual cryptography is its capability to exploit the human eyes to decrypt secret images without requiring any computation. The property of visual sharing scheme is introduced to improve the security of conventional watermarking. The experimental results show that the proposed method can withstand common image processing attacks, namely; noise adding, JPEG compression and cropping attack.
