Cloud Service Based Blockchain Infrastructure for ML Data Incentive

This project outlines a secure healthcare management system in public cloud environments by combining blockchain technology, SHA-256 hashing, and face-recognition biometric authentication. Blockchain provides a decentralized, tamper-evident ledger for encrypted medical records, ensuring data integrity and transparency, while SHA-256 hashing verifies that sensitive information remains unaltered (irjmets.com). Face recognition processed via Mobile Edge Computing offers seamless, low-latency user authentication. The architecture comprises a Python-based face-recognition microservice, a Spring Boot backend implementing role-based access control, and a React frontend for clinicians and patients. It supports encrypted storage, privacy-preserving anonymous authentication, and robust defenses against threats like replay and impersonation attac
