A Chaotic Watermarking Algorithm Based on HVS

In this paper,a novel human visual system (HVS)based chaotic watermarking algorithm is presented. Watermark signal is generated by chaotic array, which is formed by two 1-Dlogistic sequences. A HVS model is exploited to embed the watermark adaptively. The chaotic watermark is embedded into the sub low frequency coefficients of DCT domain, keeping the chaotic parameter and initial condition as private keys. The experimental results demonstrate that the watermark generated with the proposed algorithm is invisible and robust against commonly used image processing operations, such as loss JPEG compression, resizing and cropping and so on.
