In this paper; we proposed an idea for enhancing therobustness of extracted watermarks. Watermark can betreated as a transmitted signal, while the destruction ofattackers is regard as a noisy distortion in channel. As aresult of the viewpoint above, we provide an idea usingerror correct coding (ECC) [I] to detect and correct theerror part of the extracted watermarks. In our experiments, the results show that the robustness of a watermark with ECC is much better than the traditional one without ECC.
