With the rapid expansion of Internet and distributed technology, multimedia security and digital rights management have been received much attention in the literature, As a major method for intellectual property right protecting, digital watermarking techniques have been widely studied and used. Extensive algorithms have been proposed for digital images. In this paper, a robust digital image watermarking scheme which applies the common transformation domain methods and evolutionary computation technique is presented. The experimental results show that the proposed scheme is robust to several common image-processing attacks, and has good perceptual quality at the same time.
