Abstract

In this paper, a new system is presented for authenticating image content using digital watermark embedding in the DWT-domain of JPEG2000. A semi-fragile signature, generated from the host signal, is embedded into the image for content verification. Generation as well as embedding of the signature is adapted to the image content for performance improvement The system is tested extensively and performance results are compared to those of methods proposed by other authors. We show that our new system outperforms the methods compared to. Our semi-fragile authentication is robust against non-malicious modifications, such as lossy compression, noise, image blurring and sharpening, changes of luminance and contrast as well as scaling. But in contrast to other methods, our authentication is secure at the same time, which we proof by different forgery attacks.
