Abstract

A technique for proving copyright ownership of images is proposed in this paper. We use the moment preserving to represent the characteristics of images. The secret key for copyright detection is generated from the image's feature and the owner's watermark/trademark. This strategy for watermarking system is wholly different from traditional works. Furthermore, a voting approach is used to improve the correctness of the computed watermarks. The experimental results show that our method can against several attacks. These attacks are done by image processing algorithms, such as filtering, lossy compression, rotation and so on. In particular, the proposed scheme is not only applicable to ordinary natural images but also to cartoon graphics.
