In recent days the computer communication and the usage of multimedia data is enormous over the Internet, that may be easily copied & distributed from one to another. So protection of these data is very important. A robust watermarking embedding system must be developed with high PSNR Values. In this paper, a watermarking system using DCT transformation technique with image padding and selector is proposed. The results assure that the proposed algorithm gives high PSNR value and least MSE value.
