Abstract:

Reversible data embedding technique embeds secret message/data into a digital cover image in a reversible fashion. With its interesting feature ‘reversibility’ quality of recovered image after data extraction can maintain good enough. Existing reversible data embedding techniques may lead to some errors during data and cover image extraction process. This paper proposes a new method for reversible embedding by adapting reserving room before encryption scheme. Here histogram shifting method is used for self-reversible embedding and LSB replacement method for data embedding. Also reversible data hiding along with encryption technique provide multilevel security for hidden communication. Moreover the proposed algorithm can take advantages of some existing reversible data hiding techniques and worked with both grayscale and color images.
