Abstract

Digital copyright protection is a bottleneck in the cross-media industry currently. In this paper, image normalization technique is used to map image into a geometric invariant space. Then, important area is extracted from the normalized image. At last, important area’s low-frequency DCT coefficients and watermark image are used to construct copyright information. Simulation results show that, without changing original image data, the proposed scheme is robust to geometric attacks and some conventional signal processing attacks. Hence it provides an effective solution for high reliability copyright protection.
