This research aims to improve and strengthen the authentication process by introducing a novel architecture for decentralized authentication. Additionally, it proposes a new approach to decentralized
data management, which is crucial for handling sensitive medical data efficiently. The proposed architecture adopts a user-centric Self-Sovereign Identity (SSI) approach. It introduces a new non-fungible token (NFT) called Soulbound token (SBT) to facilitate user authentication across hospitals.
The proposed architecture demonstrated a significant reduction in authentication time across multiple hospitals. The use of SBT ensured secure
and seamless user authentication, enhancing overall system interoperability and data security. The study successfully presents a novel decentralized authentication architecture for the healthcare domain, leveraging SSI and SBTs. This approach not only accelerates the authentication process but also enhances data security and interoperability among hospitals. Future research should explore the scalability of this architecture and its application in other sectors requiring stringent data security
measures.
