This study offers a heuristic genetic algorithm based method for message hiding in a carrier image. This approach focuses on the "before embedding hiding techniques" by trying to find appropriate places in carrier image to embed the message with the least changes of bits. Due to it, segmentation is done in order to convert the LSBs and message strings to the sets of blocks for participation in genetic algorithm. After finding the right places, secret message blocks are embedded and a key file is created to make the message extraction available by providing the data addresses. Experimental results with the least changes in image histogram (by the policy of setting an appropriate amount for the length of block bits) show the efficiency of current method.
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.
