A Novel Robust Watermarking Algorithm Based on Error Correction Coding

Information security is one of the most important challenges in computer communication. This paper proposed a novel robust watermarking algorithm with BCH error correction coding for the transmission robustness of encrypted images. Besides applying BCH Error correction coding to produce robust marks for the transmission, the scheme utilizing Ant Colony Algorithm (ACA) to pick the image contour as the embedding position for better performance against channel noises. Experiment results illustrate that the proposed scheme can improve the robustness and invisibility of watermarking against attacks, such as JPEG compression, channel Gauss noises interference and cutting operation.
