A COLOR IMAGE MULTI-CHANNEL DWT DOMAIN WATERMARKING ALGORITHM FOR RESISTING GEOMETRIC ATTACKS

摘要：

In this paper, a multi-channel DWT domain image watermarking which is robust to geometric attacks is proposed, Firstly, this DWT domain watermarking generates a watermarking template referring to one channels DWT coefficients of the image. Secondly, this watermarking template is embedded into other DWT channel of this image. Because both watermarking template and watermarking image undergo same geometric attack, self-synchronization between the embedded watermarking and watermarking image can be obtained automatically during detecting watermarking. Therefore, a high robust performance of resist geometric attack is gained. Finally, several experimental results are given to show that the proposed watermarking algorithm achieves a high robustness even if an image undergoes some serious geometric distortion attacks.
