A Novel Color Image Watermarking Scheme Based on Arnold Transform and Discrete Wavelet Transform using B Channel

Abstract

The expansion of Internet has frequently increased the use of digital media publically. Digital media can be in the form such as audio, images, text and videos to the public. In this paper we have presented a Novel color image watermarking technique using two methods Arnold transform and discrete wavelet transform . The binary watermark is processed by using error correcting coding and Arnold Transform. Arnold transform is applied for the best scrambling round and then the watermark is embedded in the Blue color channel into the Cover image. Discrete wavelet transform method is applied on the cover image for further security. The proposed method concludes to give better results compared to the simple DWT method in image sharpening, smoothening, noise tolerance, rotating, cropping, etc aspects of image transformations and enhancement.
