In this study a reversible multilevel data hiding algorithms using histogram has been proposed. Here multilevel hiding is used to improve hiding capacity and reduce the distortion. Using the property of reversibility the proposed method can recover the embedded message without distorting the original media. By evaluating joint imperceptibility and hiding capacity, three different approaches was carried out and compared. Security analysis was done through PSNR and embedding capacity. The algorithms were tested for 5 different images of size 256×256 and 512×512. The proposed method was compared with other existing reversible multilevel hiding schemes and the results were found to be better.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
