Abstract: Data hiding is widely used to hide information into covers such audio, video and image files. If the embedded information is extracted without causing visible distortion to original cover, it is known as Reversible Data Hiding (RDH). In reversible data hiding (RDH), the original cover can be losslessly restored after the embedded information is extracted. Many approaches came into existence including rate-distortion bound approach. Recursive construction is one of the approaches for rate-distortion bound. This paper presents RDH approaches via recursive codes for binary covers and steganogrpahy for grayscale covers. We built a prototype application to demonstrate the efficiency of both models. The empirical results reveal that the proposed RDH schemes are effective and used for real time applications.
