Abstract
Digital watermarking is the process of hiding information which is used to hide proprietary information in digital media like image, video, audio. In digital watermarking the wavelet based transformation scheme is an effective in image analyzing and processing. Digital watermarking emerged as a solution for protecting the multimedia data. In the previous paper [1], on the one side, consider a watermarking technique by Joint DWT-DCT methodology. These 2 combined frequency domain method eliminate the downside of each one and in the opposite of this, a blind digital image watermarking based on DWT and twin encoding methodology. In Proposed paper, we will improve the value of PSNR as compare to the previous paper.
