Prof., G.N.C.S.G.I., JABALPUR, M.P., INDIA, ABSTRACT: Digital Watermarking is a technology which is used to identify the owner, distributor of a given image. In recent years, digital watermarking plays a vital role in providing the appropriate solution and various researches have been carried out. In this paper, an extensive review of the literature related to the color image watermarking is presented together with compression by utilizing an assortment of techniques. The proposed method should provide better security while transferring the data or messages from one end to the other end. The main objective of the paper is to hide the message or a secret data into an image which acts as a carrier file having secret data and to transmit to the intention securely. The watermark can be extracted with minimum error. In terms of PSNR, the visual quality of the watermarked image is exceptional. The proposed algorithm is robust to many image attacks and suitable for copyright protection applications. KEYWORDS: Watermarking, Discrete wavelet transform, Discrete Cosine Transform, PSNR, MSE. I. INTRODUCTION DIGITAL image watermarking has become a necessity in many applications such as data authentication, broadcast
