Towards Steganography Detection Through Network Traffic Visualisation
  The paper presents initial step toward new network anomaly detection method that is based on traffic visualisation. The key design principle of the proposed approach is the lack of direct, linear time dependencies for the created network traffic visualisations. The method's feasibility is demonstrated in network steganography environment by presenting steg-tomography methodology and developing the dedicated visualisation tool. To authors' best knowledge this is the first utilization of network traffic visualisations for steganalysis purposes.
