In this paper, we present a digital image watermarking scheme that uses both human visual system and statistical properties. The scheme places watermark in discrete cosine transform (DCT) domain and spreads the watermark eect on the entire image. We have compared our proposed scheme with two other p
We analyse a recent image authentication scheme designed by Chang et al. [A watermarking-based image ownership and tampering authentication scheme, Pattern Recognition Lett. 27 (5) (2006) 439--446] whose first step is based on a watermarking scheme of Maniccam and Bourbakis [Lossless compression and
Nowadays, image authentication schemes are widely applied to ownership protection and tampering detection of digital images. In this paper, we propose an image ownership and tampering authentication scheme based on watermarking techniques, which is employed to protect the rightful ownership and dete
