MEDIVAULT: A DECENTRALIZED IDENTITY AND ACCESS MANAGEMENT SYSTEM FOR HEALTHCARE

Conventional healthcare data management systems often face significant challenges regardingprivacy, interoperability, and access efficiency. MediVault is proposed as a decentralized solutionbuilt upon the Sui blockchain network to address patient identity verification and hospital accessmanagement. This paper details the design and implementation of a decentralized application thatleverages the high speed and scalability of the Sui network for on-chain ID verification and dynamicQR Code generation for physical and digital access authorization within hospital environments. Initialtesting demonstrates successful wallet integration and low-latency smart contract execution.
