Privacy preservation has become one of the strict security requirements in some Internet services nowadays, especially in IoT-based e-health systems. This paper proposes a privacy-preserved IoT data inquiry system with DNS, one of the most scalable distributed databases on the Internet. In the proposed system, all IoT data is encrypted and transmitted over DNS payload via DNS over TLS (DoT) communication channels for the end user’s inquiry. Moreover, the communication with IoT devices uses dedicated protocols, such as CoAP and MQTT, and the IoT data transmission uses DNS protocol only among IoT gateway, DNS servers, and end terminals that run client applications inquiring about IoT data. Consequently, the proposed system can preserve user privacy even if IoT data is stored in a cloud system and transmitted via the Internet. We implemented a prototype system in a local experimental network environment, confirming that the text-based IoT data was properly encrypted before transmitting the data and able to decrypt the inquiry on the end terminal as designed. Future work includes the extensions of the proposed system for handling binary-based IoT data transmission using DoT and performance evaluations in an actual network environment.
