An Efficient Encrypted Digital Image Watermarking Scheme

Abstract

ncreasing in networked multimedia systems has an immediate need for copyright protection and security of multimedia data tha t is transferred through the network. Digital watermarking technology provides solutions for protecting multimedia data from illegal manipulations. In the proposed method, embedding of watermark is done by using Discrete Wavelet Transform (DWT) - Singular Value Decomposition (SVD), and then a private key is used for the encryption of watermarked image. At the other end the watermarked image is decrypted first using the private key then the watermark is extracted by applying the reverse process of embedding. Using DWT - SVD, modification in all f requencies allows the development of a watermarking scheme that is robust to a wide range of attacks, and without having the private key any one cannot delete or modify the watermark
