Usage of the Steganography within Highway Information and Communication Network

In this paper we propose usage of the network steganography within highway surveillance and information system as a transfer method for safety-sensitive information. Steganography methods form a covert sub-communication channel which is invisible without appropriate software support so unauthorized users are unaware that additional type of communication even exists. Each installed device can be connected to the highway surveillance centre via covert channel in order to exchange controlling, signalling or collected data. Main goal of covert channel usage is enhancement of the data and network security. In presented paper, basic properties of the various types of steganography methods and their respective features are briefly described and their utilization within highway surveillance system.
