Abstract

The rapid growth of digital technology in today´s era leads to threat of destroying authentication and copyright protection of owners, so in this paper a Discrete Wavelet Transform based digital image watermarking scheme is proposed. Features of logistic map are able to generate a chaotic image pattern with the help of which embedding and extraction of watermark is performed. The proposed scheme also shows robustness and perceptual invisibility to various attacks such as filtering, JPEG compression, noise etc. Quality of image is being evaluated with NC and PSNR, which shows that the proposed scheme performs better.
