Abstract
A new idea to use more than one transform to embed a watermark signal is proposed in this paper. It is to exploit the benefits from different characteristics of each transform to increase the robustness of the watermark systems against several attacks. Moreover, more security is added to the watermarking system due to the existence of the other transforms. The experiments show impressive results. The robustness was optimized. Higher robustness against several attacks was achieved.
