Abstract Watermarking of multimedia gives more attention in research society. This paper presents the non-blind watermarking technique; initially a watermark is reshaped and grouped into odd and even row images. Next, two level decomposition is imposed on an original image and to enrich the robustness of the technique, divide LL2 in to two shares and stack with LH1. Copyright marking process is enabled in the lower diagonal regions of stacked sub-bands wavelet coefficients. Next, the merge sub-bands are back to the original position, inverse wavelet is imposed to obtain the marked cover image. To prove authorship the cover and copyrighted image has subject to the same procedure and acquires the marked information
