ABSTRACT
Sharing and transferring information through various electronic media can be quite challenging due to the threat of hackers. Additionally, general practitioners and caregivers often find the current electronic health record (EHR) management systems unreliable, facing issues such as data manipulation and poor communication among different entities. The integration of blockchain technology with digital twins is revolutionizing the healthcare industry by providing secure and compatible platforms for exchanging medical records. This chapter examines how blockchain-based solutions and digital twin technology intersect to create secure health data-sharing platforms. We start with an overview of blockchain technology and its potential uses in healthcare, then explore digital twin technology and its significance in maintaining comprehensive and unchangeable health data records. Building on this foundation, we discuss the architectural elements of blockchain-based health data-sharing platforms, highlighting how digital twins can be integrated for data modeling and smart contract-based access control. We also thoroughly investigate security and privacy issues, including encryption methods and regulatory compliance, to ensure patient information is protected. Furthermore, we address the challenges of implementing blockchain solutions, such as scalability and interoperability, while also exploring opportunities for innovation and collaboration within the healthcare ecosystem, supported by real-world examples. Finally, we discuss future directions and emerging trends in the integration of blockchain technology and digital twins, providing insights into the changing landscape of secure health data sharing. This chapter serves as a detailed guide for healthcare stakeholders, researchers, and innovators looking to utilize blockchain and digital twin technologies to improve the security, interoperability, and accessibility of health data-sharing platforms.
Blockchain technology and digital twins are transforming the healthcare sector by improving security, personalization, and data interoperability. The decentralized and immutable nature of blockchain provides a secure framework for protecting sensitive patient information. Meanwhile, digital twins—virtual representations of patients—continuously gather and simulate health data in real time. This synergy facilitates secure, patient-controlled data sharing, promoting seamless interoperability among healthcare systems. Together, they enable decentralized clinical trials, where digital twins supply real-time data and blockchain guarantees transparency and data integrity. In the realm of predictive healthcare, digital twins offer tailored insights, while blockchain ensures the reliability and accuracy of these forecasts. Additionally, blockchain's smart contracts can streamline insurance claims and clinical trial processes, minimizing delays and reducing the risk of fraud. Digital twins also play a crucial role in monitoring medical devices and pharmaceuticals, ensuring adherence to regulatory standards, while blockchain maintains records of supply chain and compliance data for auditing purposes. The convergence of these technologies significantly enhances patient care, facilitates real-time monitoring, and fosters a more efficient and secure healthcare ecosystem.
