Aiming at the problem that the existing methods have difficulty to identify extracted watermark after signal process, this paper proposes a novel method based on synergetic pattern recognition. Synergetics offers an approach, from top to down, to the constructions of highly parallel scheme for pattern recognition and decision making. According to the synopsis of the usual watermark system, an effective recognition method has been implemented based on synergetic approach. The algorithm model is discussed in detail and used in the extracted image watermark identification. With lots of samples in the spatial and DCT domain watermark, experimental results show that the proposed method is more effective, fast and robust.
