For this type of communication, steganography is the alternative solution to cryptography (Singh & Chawla, 2014).
Steganography is a skill of hiding a message over a communication channel or link, so that the secret message is deliberately latent among other irrelevant observed information which will result in hiding the presence of communication, and is based on the use of the spaces of the information carriers which does not damage the carrier's identity.
