In this paper, we propose a hybrid watermarking scheme for digital images based on singular value decomposition (SVD) and particle swarm optimization (PSO). The two key aspects of watermarking schemes are copyright protected and robustness. In this, we are embedded the principal components of the watermark in the DCT domain of DWT subband of host image, for providing copyright protection as well as reliability. Since Scaling factor is an image dependent so we are providing it in the form of a matrix. PSO is used for finding suitable scaling factors such that to provide efficient robustness and fidelity of the scheme. Experimental results are provided to illustrate that the proposed scheme is able to withstand a variety of image processing attacks as well as imperceptibility.
