Abstract: The growth of multimedia technologies and the attractiveness of internet are dramatically increasing. All kinds of multimedia information like audio, video and images can be obtained freely and copied even edited then transmitted as one wishes. At the same time, this makes the integrity, reliability, and security of data transmitted under threat. The information security has always been a major concern. As one of the ways to solve the security problem is data hiding technology that embeds the secret data imperceptibly into the cover media by slightly modifying some of the cover elements. This paper discusses the basic principle s of reversible data hiding (RDH) as a method of covert communication in order to understand how information is embedded in the graphical representation and covers the in-depth discussion on image compression.
