Steganography is a science that pertains to the art of concealing data in a communication in such a way that only the sender and receiver know of its existance and method of access. The platform used for transmission can be anything from a paper document to a digital file. Additionally, it is more common than not to encrypt the hidden data whenever possible such as with digital files or images.
