In these days, there's been studing many kinds of the algorithm to keep ownership on multimedia products. This paper suggest an adaptive method using Cortex filter to locate the position for the key when the key is inserted on space domain in original image. The target is focused only in steel image to simplify this algorithm. The result of simulation shows improved image quality on watermarked image compared to previous method. Also under the attack to the image watermarked, out method have a good image quality and robustness in experiment.
