Adaptive DCT Based Digital Watermarking Scheme

Abstract:

The paper proposes an adaptive digital watermarking scheme based on chaos sequence and DCT transform. The scheme can choose the location for watermark inserting adaptively, and properly assign the embedding intensity in different inserting locations according to the characteristic of human visual system (HVS). On the other hand, this scheme combines chaos sequence and scrambling technique to improve the ability to withstand various attacks. The experimental results show that, the method can basically satisfy transparency and robustness requirement.
