Security of images is a major concern area as digital images are available all over world wide web. Many watermarking techniques have been developed to protect images from illegal manipulations. In this paper , we propose a watermarking technique for gray scale images in transform domain using DCT and DWT. The proposed technique was compared with other techniques and it has shown higher robustness against attacks.
