Abstract
In recent years the topic of steganography has become very popular and a lot of research is being done in this field. Reversible data hiding is a method in which the image in which the encrypted data is hidden is losslessly recovered. In this paper we have proposed such a method that the previous work done limitations can be overcome. In this paper, we embed the encrypted data in the image by using LSB matching technique for reserving room, so that fast, optimal and lossless steganography is achieved. The proposed method provides total reversibility, that is, data extraction and image recovery.
