A histogram based image watermarking algorithm is proposed based on the invariant property of the statistic characteristic of an image for resisting geometric attacks. During embedding, a particular range of pixel values is first selected and divided into intervals according to a predefined step. Then the pixels within each interval are quantized to have the same value according to the watermark bit. During watermark extraction, the pixel values are divided into intervals using the same method as watermark embedding. A watermark bit can be extracted from each interval. Experimental results show that the proposed scheme is robust to rotation, scaling and cropping attacks, as well as some signal processing attacks.
