摘要：

This paper presents a new image watermarking scheme which is blind and robust against geometric attacks. The proposed algorithm is based on the features of radial moments. In this algorithm the radial moments were first computed and then the watermark was embedded into the differential phase of various blocks of the original image using a special type of PSK modulation called interval phase modulation (IPM). In order to embed the watermark into the phase of moments, a particular method, namely the partial calculation of moments was utilized for computation. The implementation results show the improvement in the robustness and quality of the watermarked images in comparison with other methods. (C) 2013 Elsevier Inc. All rights reserved.
