A Feature-Based Digital Image Watermarking Algorithm Resisting to Geometrical Attacks

For many kings of watermarking in digital image, geometric attackers are their weakness. In this paper, we present a new digital watermarking algorithm based on special area invariability of image, the experimental result show that the algorithm is transparent, and it not only can well resist such geometrical attacks as translation and rotation, but also has strong robust to the common image processing, such as smoothing, sharpening, addictive noise and JPEG compression etc.
