Blockchain Integration in IoT-based Smart Healthcare Systems

Blockchain technology has gained significant attention in recent years due to its potential to revolutionize various industries, including healthcare. In the context of IoT-based smart healthcare systems, blockchain integration offers numerous benefits such as enhanced data security, interoperability, transparency, and integrity. This paper explores the role of blockchain technology in securing and managing healthcare data generated by IoT devices, thereby addressing critical challenges related to data privacy, authentication, and trustworthiness. By leveraging blockchain's decentralized and immutable ledger, IoT devices can securely record and share patient data in real-time, enabling healthcare providers to access accurate and tamper-proof information for diagnosis, treatment, and patient monitoring. Furthermore, smart contracts powered by blockchain facilitate automated and transparent execution of healthcare processes, such as insurance claims processing, medical supply chain management, and patient consent management.
