Abstract
Watermarking on multimedia gives more attention in research society. In this non-blind watermarking approach a watermark is reshaped and grouped into odd and even images. Next, wavelet is imposed on an original image and to enrich the robustness of the technique, watermarking process is enabled only in the upper diagonal regions of middle level wavelet coefficients. Further, the backward process is taken place to obtain the watermarked image. To prove ownership, original and watermarked image have undergone the same operation and acquire the copyright information. Experimental results indicate that the quality of the watermarked image is better also this algorithm is robust against filtering and geometrical attacks.
