Abstract

To guarantee copyright protection and integrity authentication simultaneously, this paper proposed a dual digital watermarking scheme: Transform the image by a two-stage wavelet transform, embed a robust watermark in the low frequency sub image and embed a fragile watermark in the high frequency sub images. A logistic chaos algorithm and a Arnold transform were used to add to the difficulty of breaking, leading to the failure of fragile watermark extraction from tampered image. The algorithm can extract a robust watermark, even though the stego image is badly damaged. It can prove a very feeble modification to the image by a fragile watermark. Theoretical analysis and experimental results show that this technique is an integrated and secure scheme for multimedia production protection.
