Abstract.A novel image watermarking scheme based on the statistics of the blocked DCT coefficients. The watermark is embedded into the middle frequency of those DCT coefficients by modulating the number of those positive and negative coefficients. In order to achieve better robustness and imperceptibility, multi-objective particle swarm optimization (MPSO) has been used in the watermark embedding and extracting procedure. The particle swarm optimization is applied to obtain optimum multiple scaling factors and the embedding strength. The experimental results show that the proposed scheme has significant improvement in term of imperceptibility and robustness under various general attacks.

“…"As more and more commercial vendors use the network to deliver the multimedia products for profit, the issues about how to protect these information from pirating, masquerading, as well as to claim the ownership rights of these data become inevitable" [1]. Digital watermarking, which permanently and unalterably marks a unique and visually imperceptible signature on a digital media product, enables the owner or distributor not only to claim ownership of the product but also to trace it in the case of illicit dissemination.…”
