Single Key Based Encryption & Embedding Algorithm for Reversible Data Hiding

  Rupali Chandrakar,  Rashmi Shrivas

A novel reversible data hiding algorithmic rule with improved security, which might recover the first image in severable manner with none distortion from the marked image once the hidden knowledge are extracted, is conferred during this paper. Within the content owner aspect image is encrypted by key derived random permutation algorithmic rule. {the knowledge| the info |the information} hider then hides some knowledge into the encrypted image by histogram modification primarily based data hiding, creating use of secrete key. At the receiver aspect, if the receiver has solely secrete key, then the decrypted image with high similarity with cover image will be obtained, however cannot scan the hidden knowledge. Lower bound of Peak Signal to Noise ratio (PSNR) of this technique is way more than the previous method (75.78108dB). If the receiver has only secreted key, then the hidden data will be extracted out, however cannot scan the content of the image. If the receiver has secrete key, he might initial extract the info exploitation secrete key so decode the image exploitation same secrete key. the tactic additionally contains a higher data hiding capability than the prevailing reversible data hiding techniques in encrypted image.

Keywords- Reversible data hiding; image encryption; PSNR; key generation.
