“…Mogą to być niejawne transmisje stosujące fale akustyczne z zakresu częstotliwości niesłyszalnych dla człowieka [6,7], emisję niepożądanego promieniowania elektromagnetycznego [8,9] a nawet sterowanie temperaturą elementów wewnętrznych komputera [5]. Istnieją również kanały komunikacji skrytej, w których korzysta się z termowizji [10] i zjawisk towarzyszących procesowi odczytu matrycy mikrobolometrycznej [11].…”

“…Ponieważ zmiany natężenia promieniowania cieplnego nie są widoczne dla ludzkiego oka oraz niewielkie zmiany natężenia promieniowania cieplnego mogą nie być zauważone w termogramie przez obserwatora, możemy mówić o takiej metodzie transmisji, jako o metodzie steganograficznej. Podobna koncepcja, stosująca aktywne oświetlanie laserem została przedstawiona w [12]. Wyobraźmy sobie sytuację, w której kamera termowizyjna obserwuje scenę zawierającą rezystor -najprostszy pasywny element elektroniczny (Rys.…”

The article presents a new concept of using thermography – steganography in thermography. Steganography is a technique of hiding information in a non-obvious way and belongs to the field of science related to information security. This article examines three examples of steganographic channels – covert communication channels that use thermal imaging devices in three different ways. The first proposed method uses the possibility of alternating the scene observed by the infrared camera in a way that additional information is included in the thermogram. The second method, called ThermoSteg, uses modification of one of the parameters of the thermal imaging camera (integration time) to embed the signal containing hidden information. The third method is based on digital thermograms and the methods of replacing dead pixels in them by creating the so-called zombie pixels carrying secretive information. Three methods have been implemented under real conditions and proven to work in practice.

“…Covert channels created this way enable covert transmission with a bitrate of 8 bits per hour at a distance of up to 40 cm. Another example of hiding data in a non-obvious way with the use of thermal signals is presented in [ 24 ]. The method presented is based on the active heating of material by means of laser radiation.…”

The article presents a new concept—steganography in thermography. Steganography is a technique of hiding information in a non-obvious way and belongs to sciences related to information security. The proposed method, called ThermoSteg, uses a modification of one of the parameters of the thermal imaging camera—integration time—to embed the signal containing hidden information. Integration time changing makes the microbolometer array heat up while reading the sensors. The covert information can be extracted from the stream of thermograms recorded by another thermal camera that observes the first one. The covert channel created with the ThermoSteg method allows the transmission of covert data using a thermal sensor as a wireless data transmitter. This article describes a physical phenomenon that is exploited by the ThermoSteg method and two proposed methods of covert data extraction, and presents the results of experiments.
