Blockchain and Biometric Systems Integration for IoMT Security

In the rapidly evolving landscape of the Internet of Medical Things (IoMT), the demand for robust and trustworthy identification systems has become paramount due to the sensitive nature of healthcare data. Traditional identification methods, such as passwords, tokens and smart cards, are increasingly being replaced by advanced biometric systems, which provide a higher level of security and protection. The rapid advancements in biometric technology, with its potential to uniquely identify individuals, have driven its integration into a wide range of healthcare applications. Meanwhile, blockchain, a decentralized and immutable ledger technology, offers a powerful solution to address critical challenges in IoMT systems, including data security, privacy and trust. The integration of biometric systems with blockchain introduces innovative approaches for secure identity management and authentication, enhancing both security and trustworthiness in digital healthcare environments. This paper explores biometric systems and blockchain technology and their convergence within IoMT systems, focusing on how this combination strengthens the security and trustworthiness of healthcare systems. It also presents a comparative analysis of existing approaches and provides insights into their practical applications and potential for future advancements in secure IoMT systems.
