Rajeev Kumar, Suhel Ahmad Khan · British Journal of Healthcare Management · 2025
In the dynamic environment of healthcare technology, the emergence of biometrics has ushered in a new era of personalised and efficient healthcare solutions. The integration of biometric data promises key advancements in care, but it also raises critical concerns regarding the security and privacy of sensitive medical information. In response to these challenges, blockchain technology may offer a decentralised and tamper-resistant framework for securing biometric data in the healthcare sector. This article explores the role of blockchain in addressing security needs and fortifying the integrity of biometric healthcare data. The authors also examine the privacy and security concerns related to the healthcare ‘metaverse’, focusing on issues associated with the use of blockchain for advanced healthcare solutions. By providing an immutable ledger, secure access controls and transparent consent management, blockchain can help to safeguard patient privacy and ensure the ethical use of biometric information in healthcare services. The potential impact of this technology on the future of patient-centric healthcare systems is discussed.
