Distinct Revocable Data Hiding In Ciphered Image
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 6
Abstract
Abstract: This scheme proposes a secure and authenticated reversible data hiding in cipher images.Nowadays, we pay more attention to reversible data hiding in encrypted images, as the original cover can bereversibly recovered after embedded data is retrieved. In the first phase, the content owner encrypts the originalimage using an encryption key. Then, a data hider compresses the least significant bits (LSB’s) of the encryptedimage using a data hiding key to create space to store some additional data. Then, if a receiver has the datahiding key, he can extract the additional data from the encrypted image though he is unaware of the imagecontent. If the receiver has the encryption key with him, then he can decrypt the data to obtain an image similarto the original image. If the receiver has both, the data hiding key as well as the encryption key, then he can extract the additional data as well as he can recover the original content.
