Steganography, introduced in 2003, is a techniques employed for concealed message transfer among two secret parties. It is an ability of hidden message transfer. It also relates to the areas like network protocols and security for practical data hiding in communication networks using Transmission Control Protocol/Internet Protocol. The distinctive steganographic technique utilizes digitized media files as a cover medium for hiding data. Network steganography uses message transfer protocols such as TCP/IP. Such methods make it harder to discover and eradicate. In a typical steganography using network the alteration of a distinct network protocol occurs.
