Ameliorated Reversibility in RDH-DSC of AES Encrypted Images for providing Authentication

The proposed paper discusses a technique to retrieve the encrypted images to obtain a better efficiency and embedding rate than other methods. This method infuses the Distributed source coding technique to improvise the hiding technique thereby ameliorates the reversibility rate. The flow of the technique goes as follows: Original image which is encrypted with the Advanced Encryption Standard (AES) and is hidden using Distributed source coding (DSC) technique. The former process is done by the possessor of the image and the latter is done by the data hider. The receiver can felicitate the image using the embedding key. If the receiver is provided with the encryption and embedding key, he can recover the original image with high security and lossless original data. Thus, this method is an exception compared to the existing technologies.
