For making more secure data transfer from sender to receiver through a channel due to fast growing in internet, various techniques are used. In this paper, the authors use steganography technique which is based on cryptography. Their proposed paper is divided into two methods. One works on individual ASCII code digit pair differencing in which, they encrypt the original data in ASCII code differencing by constructing digit pair of each ASCII code digit as an individual digit pair vertically.
