Steganography, introduced in 2003, is a techniques used for hidden communication between two covert parties. It is an art of hidden communication. It also relates to the areas like network protocols and security for practical data hiding in communication networks using Transmission Control Protocol/Internet Protocol (TCP/IP). The typical steganographic method utilizes digitized media files (images, video and audio files) as a cover medium for hiding data, network steganography uses communication protocols such as TCP/IP. Such methods make it harder to detect and eliminate. In a typical steganography using network the modification of a single network protocol occurs. Such modification can be applied to the Protocol Data Unit. Network steganography sheltersa broad spectrum of techniques.
