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. The detection of steganographically encoded packages is called steganalysis.
