Title: Difference Histogram Analysis of Several Reversible Data Hiding Schemes
Authors: Muhammad Khurram Khan
Issue Date: 2009
Publisher: IEEE PrimeAsia’09, Shanghai, China, 2009.
Abstract: 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 of natural image is much less than that of the watermarked image. Then the presence of hiding message can be detected according to the distance between the horizontal and the vertical difference histogram. Experimental results demonstrate that our approach is effective.
