摘要：Digital watermarking has become one of the most popular copyright protection methods. According to human perception, the digital watermarks can be visible and invisible. Visible watermark places a watermark over an image in such a way that it is visible to all the users about the owner of the image. The invisible watermark is done in such a way that watermark content is hidden from the user. In this paper, we presents both visible and invisible watermarking methods applied on digital images for copyright protection. In our purposed scheme we apply DWT (Discrete Wavelet Transform) to both visible and invisible methods. The proposed scheme is implemented with the help of GUI (Graphical User Interface) in MATLAB . After this, we will compare the results of visible and invisible watermark on the basis of BER(Bit Error Rate), MSE(Mean Square Ratio) and PSNR(Peak Signal To Noise Ratio).
