Digital Watermarking Algorithm for Embedding Color Image using Two Level DWT

Digital watermarking is an important technique that deals with information hiding which is used to hide proprietary information in digital media like photographs, digital music, or digital video. In this paper we present a technique on digital watermarking for real time application. We have implemented the digital watermarking on image by applying two level Discrete Wavelet Transform by which we embed watermark and for extraction apply Inverse DWT transform. The performance of image is calculated in terms of PSNR & MSE
