HealthSense: A medical use case of Internet of Things and blockchain

Blockchain and Internet of things are the most promising and upcoming technologies. Blockchain is a distributed, peer to peer database forming a chain between multiple blocks of data. The internet of things works on a similar paradigm where multiple devices are connected to the internet forming a network of networks. Combined together they offer solutions for various problems, especially in the field of healthcare where quick reporting of data or results is of utmost importance. Recent studies have proven that delays in providing healthcare are directly linked to patient confidence and chances of recovery. An unreliable storage of health records has only aggravated the problem. Our paper aims to provide a solution for these issues by proposing a Blockchain-Internet of things model where a bio-sensor measures and collects real time data with respect to a patient's medical status and stores it in the blockchain. In this way quick reporting and tamper proof storage of data occurs. By deploying a smart contract the final hospital bill can be calculated along with insurance coverage. This would negate the need of third party providers and create a transparent system. Our paper also proposes the use of Inter planetary file system to store discharged patients records thus reducing the load on the actual blockchain. Overall this will surely benefit patients and doctors alike by creating a safe and transparent environment along with quick response to a patient's need.
