Design of New Stegano-Cryptosystem Based Non-Hiding Principle

Abstract

Abstract: In this work, we'll develop a novel text message steganography concept. In the proposed system, in fact, there is no hiding process in the cover-image, but the image is very important in retrieving the plaintext after it has been encrypted. The suggested system depends on comparing the bits of message, want to be hidden, with bits of the cover image, if they are similar then the index of the similar bit is recoded. After finishing all the message text, we obtain a list of indices, these indices are encrypted. Lastly, the image and the encrypted indices are being send to the receiver part. This style means no hiding be done in the image cover. The cover-images are shown before and after the acts of the proposed stego-system to prove that’s no effects have done in the cover-images.
