In modern healthcare systems, quick and secure access to patient medical records is very important, especially during emergency situations where the patient may be unconscious or unable to communicate properly. This paper presents BioMedLink, a fingerprint-based medical record retrieval system designed to provide fast and secure access to patient information using biometric authentication. The system captures fingerprint data, performs feature extraction, and matches the generated fingerprint template with records stored in the hospital database. If the record is unavailable locally, the system sends a secure request to a centralized healthcare hub connected with multiple hospitals. After successful authentication, patient medical details such as previous diagnoses, treatment history, and emergency-related information can be retrieved in real time. The proposed system uses SHA-256 hashing, encrypted communication, role-based access control, and audit logging to maintain data privacy and system security. The platform is developed using React, Node.js, Express, Python, and MongoDB to ensure scalability and smooth inter-hospital communication. The proposed framework helps improve accessibility of medical records, reduces retrieval delay during emergencies, and supports better coordination between healthcare institutions.
