In recent times a lot of work has been carried out in the field of reversible data hiding (RDH) to prevent the secret data from theft, illegal copying and unlawful reproduction. In RDH the cover image will be recovered after extracting the secret data which was embedded in that image. Finding the best location to hide the secret data is an important task so that it will conceal the existence of the message. This paper provides a reversible data hiding technique based on Firefly algorithm (FA). The optimal location to hide the secret data will be found by firefly algorithm. The histogram shifting technique is used to embed the secret data in the cover image. Histogram Techniques have attracted increasing interests due to their low computational complexity, high visual quality and can achieve good performance in terms of PSNR values.
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.
