Abstract:

Watermarking technique is used for protecting copyright of digital images. In this paper, we propose a novel technique for watermarking using DWT and SVD. DWT ensures imperceptibility of the watermark and SVD ensures its robustness against attacks. To address the issue of watermark security, we make use of Arnold transform. Watermark extraction is semi-blind, which avoids the need for original image for extraction. Both watermark and cover image are color images. Performance of the system is judged by using PSNR and Correlation Coefficient values. System shows good robustness against noise, JPEG compression, filtering and cropping.
