A new concatenated digital watermarking system that combines in a serial manner both “holographic” transform domain and image-normalized method has been proposed and developed. Since the first procedure is resistant to watermarks removal attacks as cropping of windows, removal of rows and columns and JPEG compression, and the second procedure is especially robust against geometric transforms, we get a watermarking system embracing a resistance to the above mentioned attacks. The image corrupting after concatenated watermark usage and error correcting codes applying in order to improve a reliability of fingerprinting application of watermark have been also investigated.
