Design of a Digital Watermarking Scheme Based on Logistic Mapping
A chaotic digital watermarking scheme based on logistic mapping was introduced. In the frequency domain, the chaos sequence embedded in DC component DC through using discrete cosine transform (DCT). Being of human visual system(HVS) masking properties, the watermarking adapt itself into the image, which ensure the watermark is invisible.
