Encrypted image, Reversible data hiding, Image encryption, Reversible image transformation, Privacy protection.

Presently, a new reversible image transformation technique is proposed, this technique not only enhances the quality of the encrypted image but also it can restore the secret image in lossless manner. Furthermore, is delegate data to the cloud. Therefore, the cloud can easily add additional data into the encrypted image by any RDH methods. It is very crucial to secure data and allow the cloud server to manage the data at the meantime. Under such demands, proposes a method of Reversible Data Hiding in Encrypted Image based on Reversible Image Transformation. Other from all existing encryption methods, RIT based method allow user to transmute the data of original image into another target image with the same size. Which secure the original image, the transmuted image which appears like the target image which is used as the encrypted image, and the transmutation can be done between the micro blocks with small size, which enhance the quality of the encrypted image.
