ASSURING RIGHTFUL OWNERSHIP FOR DIGITAL IMAGES USING INVISIBLE WATERMARKS

摘要

Today, many people are so conscious on intellectual property rights that lots of good solutions have been carried out to protect them. Digital watermarking is among of those ones. In this paper, we are going to describe a novel wavelet-based watermarking scheme which is designed to prevent the affection from any combination of attacks such as blurring, sharpening, noise, cropping, shifting, scaling, and rotating, that seek to eliminate the embedding watermark. In addition, the proposed watermarking system is very practical that the original image and watermark are not required during the watermark extracting phase, and the system can easily be extended to process different types of images. According to our experiments, our proposed system appears good results in its robustness.
