Multifactor Authentication with Blockchain for Secure Data Sharing in an Iomt Enabled Ambient Assisted Living Healthcare

Abstract

In the Ambient Assisted Living (AAL) environment, Internet of Medical newlineThings (IoMT) devices are widely employed to allow the elderly to remain at home newlineindependently and securely. The IoMT-integrated AAL system is an arrangement of newlinemedical devices and sensors that are continuously in real-time monitoring the health of newlinethe elderly and transmitting immediately gathered information to healthcare staff and newlinecaregivers for the delivery of timely care and support; while such systems effectively newlineimprove healthcare through the delivery of invaluable information regarding the health newlinestatus of the elderly, such systems pose significant challenges to healthcare information newlinesecurity, a concern investigated by this work through the development of a security newlineframework that will address various issues within data protection in the IoMT newlineenvironment. newlineThe improved CLEFIA algorithm-based security framework for IoMT newlinedevices is the proposed security model for IoMT devices, which is much better than newlinetraditional methods in terms of security strength in balanced, imbalanced, and randomorder newlinescenarios. It also performs well in communication overhead and computational cost. newlineThe architecture uses RBAC, MAC, improved CLEFIA encryption, and blockchain newlinetechnologies to reduce vulnerabilities, protect data, and work with different IoMT newlineconfigurations. This solution offers a scalable and all-encompassing answer to IoMT newlinesecurity issues. The architecture enhances patient trust in IoT healthcare systems by newlineprioritizing safety. Operating with optimal efficiency and real-time monitoring newlinemechanisms, the proposed technique comprises the improved CLEFIA algorithm for newlineprivacy protection, which keeps private healthcare information secure from unauthorized newlineaccess by anyone who is not authorized to analyze it. The framework also includes newlineblockchain technology to keep data transactions secure. This technique creates an newlineimmutable ledger with guaranteed data integrity that provides an open audit trail to fulfill newlinemedical requirements. The study identifies vulnera
