This paper proposes a novel encryption scheme based on invertible watermarking. In the past encryption algorithms, diffusion and confusion algorithms are used to increase the effect of the encryption, however, these algorithms can only change the cover itself to be encrypted. In this paper, the invertible watermarking can be used to perform the encryption, which can not only use the additional information...
In this paper, we experimental investigate if the current reversible data hiding schemes are detectable. By modeling the distributions of horizontal pixel difference of natural image using generalized Gaussian model, we find that the horizontal difference histogram of watermarked image is significantly altered. Furthermore, the difference between the horizontal and the vertical difference histogram...
Ownership authentication of image attended a careful attention due to global availability of internet services. Illegal copying and misappropriation of digital image leads cyber crime in an epidemic form. In aforesaid regard we've already proposed different fragile color image authentication schemes which guarantees ownership of an image through embedding color watermarks into color host images. In...
