Blockchain for IoT and Medical Data Management

Abstract

This paper presents an innovative approach to enhance the security, sharing, and management of medical data in hospitals and clinics through the integration of blockchain technology and Internet of Things (IoT) devices. Traditional databases, while effective, may pose challenges related to data security and accessibility. In response, our proposed system leverages the inherent features of blockchain to establish a tamper-resistant and transparent framework for storing medical records. The core of our solution involves the integration of blockchain in medical data storage, utilizing Raspberry Pi devices equipped with sensors such as DHT11 for data collection. Each patient is uniquely identified and assigned an individualized ID number, acting as a secure password to access and manage their medical records. This not only ensures data privacy but also provides a seamless and secure method for patients to oversee their healthcare information. We propose a partially decentralized blockchain-based system for medical data storage, constructed from scratch using TypeScript. Additionally, we provide a proof of concept that demonstrates the practical implementation of blockchain in the realm of Electronic Health Records (EHR), utilizing a temperature sensor (DHT11) connected to a Raspberry Pi specifically designed for IoT medical records systems. This multifaceted approach contributes to advancing the field by offering a secure, transparent, and patient-centric system for healthcare data management.
