A study of enhancing the robustness of watermark

We propose an idea for enhancing the robustness of extracted watermarks. A watermark can be treated as a transmitted signal, while the destruction of attackers is regarded as noisy distortion in a channel. We suggest an idea using an error correction code (ECC) 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.
