Internet of Things Healthcare Application: a Blockchain and LoRa Approach

Blockchain technology has been seen as a holy grail, being able to solve many of the security and privacy problems related to the growing numbers of interconnected IoT sensors that needs data protection. Gradually, this innovative technology began to be addressed in other industries having an ever-increasing penetration. In this paper, the blockchain technology is integrated into an Internet of Things healthcare application, where a medical wearable device is used for human body health parameters acquisition. Collected data are secured and transmitted using LoRa (long range) technology. The proposed blockchain architecture uses Ethereum technology due to the use of smart contracts technology. From the obtained result, the proposed architecture ensures a high level of performance and security, allowing patients to have control over shared data securely, but also having the assurance that shared data will not be tampered with.
