Abstract
Image watermarking are generally utilized for copyrighting of digital images in the online world. One cannot secure its data only by this method. Therefore a new approach of using image filtering techniques with image watermarking have been successfully implemented in this paper. This research also concludes the maximum number of filtering process that can be use on the watermark image. The quality of watermark image increases as image filtering techniques are applied, but reduces the similarity index between the original and recovered watermark. Applying Mean and Median filter have proved to efficient in improving quality and making watermark image more robust in nature.
