A Review of Blockchain in Internet of Medical Things

During the past few years, especially after the emergence of the Covid-19 pandemic, researchers have devoted their efforts in improving the global health sector by supporting it with the latest technologies. Among these technologies, we often hear about Internet of Medical Things (IoMT) and blockchain in the effort of facilitating the patients and medical staff to preserve their security and confidentiality of the patient data and protect it from every hacking attempt to steal or falsify. In fact, during just the last three years alone, dozens of new schemes have been proposed in the literature for the integration of blockchain with IoMT for the healthcare field. Therefore, we present in this paper a review of some the notable works in this area. Our intent is to explain the basic principles of this field and classify the notable proposed schemes, as this study suggests potentially interesting avenues for future research to use it as a reference material by the researchers in this field.
