In today's digital world invisible ink and paper have been replaced by much more versatile and practical covers for hiding messagesdigital documents, images, video, and audio files.As long as an electronic document contains irrelevant or redundant information, it can be used as a "cover" to hide secret messages.Cryptography is the study of encoding and decoding secret messages where as Steganography is the art and science of writing hidden messages in such a way that no one apart from the sender and intended recipient even realizes there is a hidden message.In this paper we implement Hill Cipher algorithm, for hiding our text behind the cover image and decrypt the cover image to get original text.The highlight of this paper is that, the key is encrypted and scrambled within the cover image.
