Uma solução para compartilhamento de dados de saúde baseada em blockchain permissionada e internet das coisas para hospitais inteligentes

Abstract

Several technologies are being used together to improve the quality of health services. In this context, applications that use technology to benefit the health area are part of E-health technology. This type of service is growing in importance over time, being used from remote access to medical records to real-time data exchange using body sensors. Similarly, the use of blockchain technology has been growing in the health sector, due to the set of possibilities for solutions that this technology has. This technology works like a distributed ledger and allows transactions to be carried out without the intermediation of third parties. Thus, the integration of these technologies can bring a series of benefits to the health sector, such as greater availability and privacy of health data. This work seeks to provide a solution for monitoring and sharing vital signs of patients under the care of a smart healthcare institution, based on blockchain technology. For this, a solution based on four layers was developed. For the physical layer, an IoT prototype was built to measure some health variables. In the communication layer, an IoT communication middleware was used. At the storage layer, a blockchain network infrastructure was developed. And, finally, for the application layer, a prototype of a WEB application was developed. Load tests were performed to verify the system response in different scenarios. With the results obtained, the possible implementation of this solution in an intelligent health institution is noted. Also presenting a contribution in the context of applications that integrate E-health and blockchain.
