In this paper, a novel robust watermarking technique based on discrete cosine transform using genetic algorithm (GA) is presented. To obtain highest possible robustness without losing transparency, GA is used for adjustment of mid-band coefficients. Significant improvements in robustness under attacks and also in transparency are obtained from experimental results.
