Abstract: This project aims to enhance the security and functionality of hospital management systems by implementing robust encryption techniques and access control mechanisms. The system allows the addition of doctors, who are required to obtain permission from the hospital before being granted access. Only authorized doctors are permitted to interact with patient data, ensuring that sensitive medical information remains secure. To protect patient data, the system includes an authentication process where user IDs and passwords are verified. If a mismatch occurs, the system detects and flags the access attempt as coming from a malicious user. The system also allows doctors to view patient details and send prescriptions, ensuring a smooth workflow for healthcare providers. Furthermore, medical staff can add and manage medicines within the system. To safeguard sensitive information, the project integrates the use of SHA-256 (Secure Hash Algorithm) and AES (Advanced Encryption Standard) encryption algorithms. These encryption methods ensure that all user data, patient records, and prescriptions are securely encrypted before being transmitted or stored, preventing unauthorized access and ensuring the privacy of all users.
