This project introduces an advanced framework for enhanced security and efficient data sharing in e-healthcare systems, utilizing Elliptic Curve Cryptography (ECC)-based encryption. The system consists of three integral modules: Doctor, Patient, and Cloud Server. The Doctor module facilitates secure registration, login, appointment management, and prescription uploads. The Patient module ensures secure registration, login, symptom uploads, appointment booking, and report viewing, with all data encrypted using ECC to ensure the confidentiality and integrity of sensitive medical information. The Cloud Server module handles user authentication, doctor authorization, and patient data management. By leveraging ECC, the system provides a robust solution for secure data transmission, safeguarding healthcare data against unauthorized access and cyber threats. This approach ensures privacy, enhances trust in the healthcare system, and facilitate authorized data access, improving overall healthcare service delivery.
