Information Hiding and Recovery using Reversible Embedding

The main objective of this work is to develop data embedding technique that not only embeds secret message, in the form of binary bit stream, to the host image without any auxiliary information or location map, but also extracts that embedded secret message at decoder and restores the original content of host image, which are manipulated after the embedding at encoder. This technique carried out in two phases, embedding and extraction, using min-max approach. This technique reduces extra overhead to embed extra information other than secret message.
