WATERMARKING ALGORITHM BASED ON CHAOTIC SEQUENCE AND DWT

摘要：

In this paper, a method for watermarking of chaotic sequence and DWT is proposed. Firstly, the original watermark was encrypted by chaotic sequence mapping and embedded into the low frequency sub-band. The coefficients whose energies were larger than the others were selected to hide watermark, and the hided watermark strength was determined by the energy ration between the selected coefficients energies and the sub-bands mean energy. The retrieving watermark algorithm and the blind detecting algorithm were designed in accordance with the embedding scheme. Simulation results show that this method can gain high fidelity and high robustness, especially under the typical attack of geometric operations.
