Image watermarking particularly has attracted lot of attention in the research community. In this paper we propose a multiple watermarking based on DWT with the motivation to maintain the quality of the image. The original image was interlacing into even and odd rows of images and deinterlaces the two images. For hiding watermark images wavelet based approach is employed in two deinterlace images. Stack the two watermarked images in to single image by introducing zeros of even and odd rows in the two watermarked images, At the end again interlacing and deinterlacing of an images and extracts both the watermark Images. Simulation results show the watermark imperceptibility and robustness. Also the quality of the watermarked image is excellent and there is strong resistant against many geometrical attacks.
