Digital watermarks is an important technique for protection and identification that allows authentic watermarks to be hidden in multimedia such as image, audio, and video. Watermarking has been developed to protect digital media from being illegally reproduced and modified. The embedding and extracting watermark used to require complex procedures. In this paper, a Full Counter-propagation Neural Network (FCNN) is applied to digital image watermarking, in which the watermark is embedded and extracted through specific FCNN. Different from the traditional methods, the multiple cover images and the watermark are embedded in the synapses of a FCNN simultaneously instead of the cover images. Therefore, the watermarked image is almost the same as the original cover image. In addition, most of the attacks could not degrade the quality of the extracted watermark image. The experimental results show that the proposed method is able to achieve robustness, imperceptibility and authenticity in watermarking.
