Information embedding systems in digital images have various important multimedia and high precision applications. Such systems embed one signal into another. In recent years, more attentiveness is paid towards Reversible Data Hiding (RDH) in encrypted images. The reason behind is, it maintains the property that the original cover can be loss recovered after the embedded secret data is extracted while preserving the image content's secrecy. All the previous methods of reversible data hiding were vacating room for data hiding after encrypting the image, which results in the introduction of some error rates at the time of data extraction and image recovery.
