"In this paper, the authors relate the areas of steganography, network protocols and security for data hiding in communication networks employing TCP/IP. Steganography is defined as the art and science of hiding information, which is a process that involves hiding a message in an appropriate carrier for example an image file or IP Header. The carrier can then be sent to a receiver without anyone else knowing that it contains a hidden message. In this paper, they present a scheme to send message imperceptibly between points over Internet using any encryption algorithm which is used to encrypt secret message, and then embeds the modulated message into identification field of IP header."
