Abstract
The existing digital image editing tools have made the authentication of digitalimages an important issue. The objective of this paper is to propose an image authenticationscheme, which is able to detect malicious tampering while tolerating someincidental distortions. By modeling the magnitude changes caused by incidental distortionand malicious tampering as Gaussian distributions with small and large variances,respectively, we propose to embed a watermark by using a mean quantization ...Keywords
