Terroristen haben es zukünftig schwer: Denn verdeckter Informationstransfer über VoIP und Handy kann wirkungsvoll unterbunden werden. Durch gezielte Veränderung von Datenpaketen wird die erfolgreiche Übermittlung geheimer Nachrichten in Audio- und Bilddateien verhindert, ohne die normale Sprach- und Bildübertragung zu stören. Das ist die effizienteste, sicherste und günstigste Methode, um den unbemerkten Transfer verschleierter Botschaften - die so genannte Steganografie - zu erschweren. Zu diesem Ergebnis kommen die IT-Security-Experten der Fachhochschule St. Pölten, Österreich, im Forschungsprojekt StegIT, bei dem auch das österreichische Bundesministerium für Landesverteidigung und das Bundeskriminalamt beteiligt waren.
