Sumstega: summarisation-based steganography methodology
by Abdelrahman Desoky
International Journal of Information and Computer Security (IJICS), Vol. 4, No. 3, 2011

 

Abstract: The demand for reading while no one has time to read everything has fuelled the necessity for automatic summarisation systems in business, science, World Wide Web, education, news, etc. Thus, the popular use of summaries by a wide variety of people creates a high volume of traffic for accessing and generating summaries. Such huge traffic makes an adversary's job impractical to investigate all of them and allows communicating parties to establish a secure covert channel to transmit steganographic covers. This renders summaries an attractive steganographic carrier. Therefore, summarisation-based steganography methodology (Sumstega), presented in this paper, takes advantage of the automatic summarisation techniques to generate summary-cover. Sumstega neither hides data in a noise nor produces noise. Instead, Sumstega manipulates the parameters and factors of automatic summarisation techniques in order to embed data without noise, which retains adequate rooms for concealing data. The validation demonstrates the capability of achieving the steganographic goal.
