Increasing attention has recently been paid to reversible data hiding (RDH) in encrypted images as it maintains the excellent property that the original cover can be retrieved without loss after extracting embedded data while protecting the confidentiality of the image content . All of the above methods encapsulate data by reversible space separation of encrypted images, which may be subject to some errors in data extraction and / or image restoration. In this work, we propose a novel method reserving space before encryption with a traditional RDH algorithm, and therefore it is easy for data to reversibly incorporate data into the encrypted image. The proposed method can achieve real reversibility, ie, data extraction and image recovery are free of any errors. Experiments show that this new method can embed more than 10 times as large payloads for the same image quality as previous methods, such as PSNR = 40dB.
Now one day there is a very large problem of data hacking in the age of networks. There are several techniques available in the industry to overcome this problem. Therefore, the hidden data in the encrypted image is one of the solution, but the problem is that the original cover can not be recovered without losses by this technique. That is why Recent attention is increasingly given to reversible data hiding (RDH) in encrypted images, as it offers the excellent property that the original cover can be retrieved without any embedded data while protecting the confidentiality of content the picture. This document covers the various data methods that are hidden in the image as differential expansion, histogram change or the combination of both techniques. This is useful in the way these methods retrieve the image with its original quality with an improved PSNR ratio.
