Difference expansion based near reversible data hiding scheme

Abstract

Reversibility is being widely explored in these days due to the emerging applications in remote sensing, medical imaging, and military communication. The new paradigm of near reversible data embedding has to be explored further. Recently, very few data embedding techniques have been presented in spatial and frequency domains. This paper presents a near reversible technique in spatial domain which partially uses the difference expansion technique for hiding the secret data into the cover content.
