Abstract: The present paper focuses on the mixture of Discrete Wavelet Transform and Discrete Cosine Transform used in the purpose of Digital Image Watermarking. People nowadays need Digital media as an alternate of paper media. With the growth of technology, digital media while transferring requires protection through internet or other mediums. Process of hiding information in any form image, text, audio and video in original image without corrupting its perceptual quality is called Digital Image Watermarking. Watermarking is useful method for protection of integrity of the original data, it is done by computing statistical values like Peak signal to noise ratio (PSNR) & Mean square error (MSE) for various attacks like image cropping, noise and resize.
