Data Transmission between IoT Modules using Audio Steganography

Data in sensor networks, transmitted usually between IoT modules, should be protected from unauthorized access to prevent erroneous actions with fatal consequences. Methods should be applied to encode or hide the transmitted data. This paper proposes to apply audio steganography methods to hide the data. An algorithm and program modules have been developed. The main experimental results demonstrating the correct and reliable hiding of data transmitted between IoT modules are briefly presented applying the proposed algorithm based on steganography.
