Abstract
The Internet of Medical Things (IoMTs) are critical components in wearable healthcare applications such as bio-systems, rehabilitation robots, activity identification, to name a few. Traditional security measures are unable to protect data from harmful attackers. Patients' privacy may be endangered as a result of eavesdropping, and the diagnosis of life-threatening diseases may be delayed as a result of IoMT device malfunction caused by attacks such as Denial of Service (DoS) attacks. Blockchain has emerged as a possible answer to these problems. The benefits of adopting blockchain based into the healthcare ecosystem include decentralisation, dependability, efficiency, security, and privacy, to name a few. Biometric systems have been rapidly gaining traction in a variety of industries in recent years, and they continue to provide enhanced security for access control systems. In comparison to traditional procedures, security methods based on biometric features give more trustworthiness while requiring less processing. As a result, biometric traits are used in current healthcare systems to implement security in healthcare. This research work proposes a secure blockchain based architecture for IoMT based healthcare applications that can provide decentralized and secure communication while taking into account the constraints listed above. Bio-keys, in combination with biometric authentication are also offered as a way to further enhance the security.
