Hiding secret message using matrix reordering and image blocking

Image Steganography is a solitary concept of hiding a data inside the image. As there is an expansion of interconnected networks so users exchange their information over the channels but transmission is hardly secure. So there is a concept of Steganography which is a proficiency of deceptive transmission of secret deets concealed inside other media. This paper proposes a new model in which capacity of data embedding is increased by using LSB2z algorithm and security is also increased by using Matrix Reordering and Image Blocking.
