Reversible Data Hiding In Image- A Literature Survey

Krishnapriya K R


Security must be provided for the transmission of confidential and sensitive data over the network.To increase the security of data transmission, data hiding can be performed in encrypted image .Therefore the security of image and embedded data is maintained. The hidden data and the cover image can be restored thereby reversibility can be achieved, which is termed as Reversible Data Hiding. By using combined lossless and reversible data hiding, the embedded data and cover image can be retrieved. This paper focus on the various works in the area of reversible data hiding and various RDH techniques are discussed.
