Abstract:	In this paper, we proposed an idea for enhancing the robustness of extracted watermarks. Watermark can be treated as a transmitted signal, while the destruction of attackers is regard as a noisy distortion in channel. As a result of the viewpoint above, we provide an idea using error correct coding (ECC) [1] to detect and correct the error 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.
