Mediblock

Abstract

Healthcare information systems often rely on centralized storage models that expose sensitive patient data to security risks and limited interoperability. This paper presents MediBlock, a decentralized framework designed to enhance healthcare data management through the integration of blockchain and cloud technologies. The system ensures secure storage, traceable insurers. Smart contracts regulate permisiions and maintain transparency trough immutable audit trails. The proposed architecture improves trust, privacy, and efficiency in handling medical records. By enabling distributed access and encryption-based protection, MediBlock contributes toward reliable healthcare information exchange while supporting scalability and integration wit existing infrastructures.
