Reversible data hiding with image encryption is a technique, in which a secret data is embedded inside a confidential image in such a way that, at the receiver side, both the image and the data can be extracted without any loss. Existing data hiding methods embed data by vacating room after image encryption. This may lead to error during the data extraction and the image recovery. However secure reversible data hiding embed the data before image encryption with a RDH technique, such that the data hider can reversibly embed the data in an easy manner.
