In this paper, a highly robust watermarking scheme based on Discrete Wavelet Transform DWT is proposed. It has the following features. First, unlike conventional proposed watermarking techniques, a watermark is embedded into the lowest frequency components. Second, the Human Visual System HVS model is adopted to improve the transparency of the watermarked image. Several experiments are conducted to demonstrate the robustness property of this watermarking scheme. Furthermore, it is worthwhile to mention that the proposed scheme is resistant to the counterfeiting attack. In addition, comparison of the proposed scheme with other state-of-the-art watermarking schemes based on DWT shows that our scheme is more effective.
