摘要

Digital watermarking has been suggested as a solution to protect copyright and ownership of digital images. The effective watermarking scheme should satisfy imperceptibility, robustness, capacity and security requirements. In this research, the security issue and the lack of reconstruction quality of the watermark logo of the integration of Discrete Wavelet Transform (DWT), Singular Value Decomposition (SVD) and Compressive Sensing (CS) watermark technique are addressed. Wilkinson measurement matrix is proposed to increase the robustness and improve the reconstruction quality of the watermark logo in the DWT and SVD based on the CS watermarking scheme. Additionally, the security issue of the SVD is solved by sending a scrambled compressed logo then extracting U, V matrices from this compressed logo at the decoder. The proposed method not only increases security but also reduces the size of the transmitted watermark logo. The robustness of the proposed algorithm is evaluated in the presence of different attacks like signal processing, compression, geometrical and noise attacks. The simulation results demonstrate that the proposed technique is more robust than the conventional techniques for all attacks, as well as its robust security. Moreover, the quality of the watermarked image is measured and the results show that the imaging performance of the proposed technique is approximately 0.7 to 4 dB better than that of the conventional methods. Consequently, the proposed watermarking scheme proves its ability to achieve the demands of security, imperceptibility and robustness against different attacks.
