Steganalyses of Reversible Data Hiding Techniques

Abstract

Reversible data hiding is the technique that allows extracting embedding message meanwhile the cover-media can be recovered without any distortion. In 2006, Ni et al. proposed a reversible data hiding algorithm which utilizes zero point and peak point of image histogram to embed data. The advantages of this method are simple and providing good image quality. However, some statistical patterns were easy to be found during the embedding procedure. In this paper, we proposed a simple and quick steganalysis algorithm utilizing the measurement of histogram variation and the statistical analysis techniques. Experiment results shows that our method provide a good performance on natural images.
