Poster Abstract: Privacy in Blockchain-Enabled IoT Devices

Abstract

Over past two decades, the idea of Internet of Things has been adopted widely as a solution to many societal problems in different areas. These areas include but are not limited to healthcare, transportation, environment, etc. Low cost overhead of Internet connectivity feature has been the main contributing factor in the widespread use of such devices in building different IoT solutions. The original stovepipe architecture of IoT systems limits the possibility of sharing the hardware infrastructure of IoT solutions and therefore is the main barrier against novel solutions. In recent year, however, there have been efforts to come up with solutions for sharing the hardware infrastructure and therefore pave the way for innovative solutions by amortizing the capital cost of setting up the hardware. In this work, we propose an architectural guideline for blockchain enabled IoT devices which facilitates sharing them between multiple blockchain ecosystems and at the same time, ensures the exclusive access to them seamlessly through blockchain smart contracts.
