Reversible data hiding technique allows to embed information inside an image in such a way that both image and information can be extracted at the receiver side without any loss. In this work the image is first encrypted and information is hidden in the encrypted domain. With the help of the data hiding key, the recipient can extract the data without decrypting the image. However using data hiding key and encryption key, the authorized person can recover the original image and the data without any loss. This reversible data hiding technology has its application in medical and military area.
