Steganography (Part 3, Fundamentals)

Steganography just hides the covert message and not the communicating with each parties. The Steganography process generally is putting a hidden message in some transport medium that is called the carrier. The secret message should be embedded in the carrier to form the Steganography medium. A Steganography key may be used for encryption of the hidden message. In summary:

steganography_medium = hidden_message + carrier + steganography_key
