A Testbed Implementation of a Biometric Identity-Based Encryption for IoMT-enabled Healthcare System

Historically, health data was stored locally on the hospital’s server as patient health records, and we had to rely on the planned check-up during doctor’s visits. Now, we can monitor health continuously and in real-time. Remote healthcare monitoring can also be helpful in setting up alerts, allowing early intervention and treatment. In this way, the patient gets timely treatment, avoids doctor visits or hospitalization hassles, and reduces healthcare expenses. Additionally, in an ambulance, real-time patient data can be sent to the physician via wireless communication which can save the life of a critical patient. The critical problem that arises in Internet of Medical Things (IoMT) is how securely the health vitals can be transmitted to the physician. There are numerous ways to transmit data securely to the physician, however Identity-based cryptography is the most popular these days to provide solutions for secure transmission. Identity-based cryptography is the public key cryptography in which an arbitrary string representing an individual is used as a public key. Biometric information based public key generation by identity based encryption is a potential candidate for providing a solution to such a problem. In this work, we propose using facial biometric information of the clinicians to create a public key for encrypting health vitals of a patient.
