MediTwin: A Web 3.0-Integrated Digital Twin for Secure Patient-Centric Healthcare in the Metaverse

Metaverse is an emerging research area where substantially virtualized realities and interactive digital spaces meet through augmented reality (AR), virtual reality (VR), and Internet of Things (IoT). This amalgamation confers a multifaceted platform for healthcare innovation, extending from remote surgeries to immersive patient education. Nevertheless, successfully deploying these technologies in healthcare necessitates overcoming demanding integration challenges. This paper aims to develop a strong system for integrating digital twins into the Metaverse while securing data management through leveraging blockchain technologies, Web 3.0 features, and advanced consumer electronics, which allow for dynamic interactions. The main emphasis of this approach is to address the challenges related to data synchronization and security. It aims to protect healthcare data within the Metaverse and also navigate the aspects associated with using digital replicas. The proposed system uses blockchain and provides a procedure to secure data while ensuring cryptographic strength and quantum resilience. The simulations are performed to compare the proposed approach with the existing ones, where the obtained results show that our proposed MediTwin approach has significantly improved system efficiency by increasing data synchronization speed by 20% and resource utilization by 15%.
