An End-to-End Secure Solution for IoMT Data Exchange

In the field of healthcare, the emerging concept of the Internet of Medical Things (IoMT) plays a crucial role in enhancing the efficiency of medical services and introducing innovative solutions. Traditional healthcare services are no longer adequate to meet the growing medical needs, particularly in countries with an aging population. Remote medical consultations have emerged as a viable solution, especially in rural areas facing the challenge of medical deserts. In such scenarios, instead of physically visiting a hospital, patients can opt for remote medical consultations, particularly for simple cases like medical follow-ups. The patient’s health data is collected, monitored, and processed in real-time, subsequently shared with remote doctors or hospitals. IoMT devices, which easily measure vital signs, facilitate the seamless collection of health data. However, ensuring the security and privacy of sensitive IoMT data poses a significant challenge. In this context, one potential solution to ensure the confidentiality and integrity of medical data is the utilization of Blockchain technology. This paper explores the potential of Blockchain in IoMT networks, specifically focusing on guaranteeing privacy, confidentiality, integrity, authentication, and non-repudiation of medical data collected through medical IoT devices. Additionally, a proof of concept is provided to demonstrate how Blockchain can be effectively employed to secure the sharing and storage of IoMT data among connected nodes/devices and authorized users, particularly medical entities.
