“…One of the best possible ways to deal with this is to use blockchain. This technology has tremendous promise for keeping EHR data secure as it flows from one system to another (26). Additionally, whether you're transferring EHRs inside your clinic or with other stakeholders, blockchain techniques can effectively reduce the risk of data fraud.…”

Internet of Medical Things (IoMT) is the interconnectivity of highly sophisticated medical-grade devices and software applications to work together and provide a new improved version of the healthcare environment in this era. Wearable and standalone devices use sensor technology to exchange medical information from remote areas to health workforces over a wireless network. Apart from being advantageous IoMT faces challenges like safety, cybersecurity and scalability, interoperability, verification, and validation. Interoperability deals with the exchange, interpretation, and usage of data delivered through different computerized gadgets without restrictions. Currently, there are numerous government-certified EHR products each of which has different technical, clinical, and serviceable capabilities. Being heterogeneous it becomes hard to achieve a single standard interoperability format to exchange data. The pivotal aim of this paper is to understand how interoperability plays an important role in healthcare and different ways through which it can be successfully implemented.

The integration of medical equipment into the Internet of Things (IoT) led to the introduction of Internet of Medical Things (IoMT). Variation of IoT devices have been equipped in medical facilities. These devices provided convenience to healthcare provider since they can continuously monitor their patients in real-time, while allowing them to have greater physical flexibility and mobility. However, users of healthcare services (such as patients and medical staff) often are less concerned about security issues associated with IoT. These alleviate existing problems and jeopardize the lives of their patients by making them susceptible to attacks. Furthermore, IoMT applications have direct access to healthcare services because it handles sensitive patient information. Therefore, it is extremely important to preserve and establish the security and privacy of IoMT. This further justifies the need to investigate and address the related issues. Despite existing literature on security and privacy mechanisms, the domain still requires more attention. Therefore, this paper aims to discuss the security and privacy principles, as well as challenges associated with IoMT. Besides, a comprehensive analysis of privacy and security solutions for IoMT is also presented. In addition, we introduced a novel taxonomy of IoMT security and privacy based on cyber security principles such as "govern," "protect," and "detect". In conclusion, this paper provides a discussion on existing challenges and future direction for researchers.

“…The authors in [47] described a fine-grained authorization framework that is based on smart contracts and blockchain, whose main goal is to control the access of users to medical data and devices. The private blockchain ecosystem is authenticated by a proof-of-medical-stake consensus mechanism [126] that is suitable for medical applications.…”

Recently, blockchain-based Internet of Medical Things (IoMT) has started to receive more attention in the healthcare domain as it not only improves the care quality using real-time and continuous monitoring but also minimizes the cost of care. However, there is a clear trend to include many entities in IoMT systems, such as IoMT sensor nodes, IoT wearable medical devices, patients, healthcare centers, and insurance companies. This makes it challenging to design a blockchain framework for these systems where scalability is a most critical factor in blockchain technology. Motivated by this observation, in this survey we review the state-of-the-art in blockchain-IoMT systems. Comparison and analysis of such systems prove that there is a substantial gap, which is the negligence of scalability. In this survey, we discuss several approaches proposed in the literature to improve the scalability of blockchain technology, and thus overcoming the above mentioned research gap. These approaches include on-chain and off-chain techniques, based on which we give recommendations and directions to facilitate designing a scalable blockchain-based IoMT system. We also recommended that a designer considers the well-known trilemma along with the various dimensions of a scalable blockchain system to prevent sacrificing security and decentralization as well. Moreover, we raise several research questions regarding benchmarking; addressing these questions could help designers determining the existing bottlenecks, leading to a scalable blockchain.
