“…One of the solutions to overcome all these limitations in the existing system is to introduce patient centered electronic health system namely, Personally Controlled Electronic Health Record System, in which the patient will be the universal consent provider of their data (except in emergency situations) to all stakeholders viz doctors, pharmacists, nurses, scientists etc. Blockchain technology [102] can be used as an underlying access control tool to support this distributed ledger mechanism in the cloud. A secure Blockchain based EHR system in cloud is depicted in Fig.…”

A systematic and comprehensive review of security and privacy-preserving challenges in e-health solutions indicates various privacy preserving approaches to ensure privacy and security of electronic health records (EHRs) in the cloud. This paper highlights the research challenges and directions concerning cyber security to build a comprehensive security model for EHR. We carry an intensive study in the IEEE, Science Direct, Google Scholar, PubMed, and ACM for papers on EHR approach published between 2000 and 2018 and summarized them in terms of the architecture types as well as evaluation strategies. We surveyed, investigated, and reviewed various aspects of several articles and identified the following tasks: 1) EHR security and privacy; 2) security and privacy requirements of e-health data in the cloud; 3) EHR cloud architecture, and; 4) diverse EHR cryptographic and non-cryptographic approaches. We also discuss some crucial issues and the ample opportunities for advanced research related to security and privacy of EHRs. Since big data provide a great mine of information and knowledge in e-Health applications, serious privacy and security challenges that require immediate attention exist. Studies must focus on efficient comprehensive security mechanisms for EHR and also explore techniques to maintain the integrity and confidentiality of patients' information.

EHD systems have remarkable benefits over conventional paper based records. Unlike paper-based records, EHR incurs less manpower, time and physical storage [3]. The advantages of EHRs include easier and swift clinical data access, ability to maintain effective clinical workflows, mitigation of medical errors, enhanced patient safety, reduced medical costs and better and stronger support for clinical decision-making. Realizing the benefits offered by EHD systems more than 90% of healthcare institutions in Australia have adopted this system to facilitate effective medical resource allocation and efficient healthcare [3]. The ability of EHDs to provide better management of healthcare has been ascertained and testified by various users. However the transition from conventional healthcare systems to e-health care throws unique challenges with respect to privacy, confidentiality, and security of medical information. Cloud computing is a recent paradigm in digital technology and is being extensively used in the healthcare industry [4]. It not only provides convenient storage of

“…In 2015, 140 million patient records were breached according to Protenus Breach Barometer Report. 53 The WHO estimates that many countries in Africa and parts of Asia and Latin America have areas where more than 30% of the medicines on sale can be counterfeit. 54 In 2018, the healthcare industry continued to be plagued by data breaches involving sensitive patient information.…”

Healthy population is regarded as the most valuable asset of any country. Unfortunately, the health challenges that hinder mankind's wellbeing are enormously increasing. Examples include but are not limited to: the diversity of emerging diseases afflicting the global population, the projected demographic growth of elderly people who need consistent monitoring, the deficiency in medical staff, the lower density of physicians, and the challenging geographical location of the population from healthcare providers. The mitigation of such health challenges calls for novel technologies to improve patient outcomes. In this article, seven emerging technologies, namely: Wearable Devices and Internet of Things, Artificial Intelligence, Blockchain Technology or Distributed Ledger Technology, Robotics Technology, Telehealth and Telemedicine, Big Data Technology and Nanomedicine have been highlighted. For each discussed technology, its historical background, development drivers, market status and trends, significance to healthcare, key player companies, and associated challenges have been presented. The information contained in this paper was collected from different journal articles, websites, reports, conference proceedings, and books. It was observed that though the technologies discussed in this article show growth at different rates, healthcare technology development and implementation are very promising in revolutionizing the health sector and improving the health of the population. Therefore, healthcare providers and countries are recommended to put in place Healthcare Technology Assessment Programs to help them collect data regarding the technology efficacy, relevance, safety, outcomes, and alternative technologies towards better planning for healthcare services improvement.

“…In the healthcare domain in particular the properties of blockchain can find genuine application in a range of areas (Angraal et al, 2017;Hölbl et al, 2018;Agbo et al, 2019). Active research in the application of the technology to health informatics ranges from the potential use of the blockchain as a means to store and process medical records (Zhang and Ji, 2018), being used as a permissions management layer (Azaria et al, 2016), through use as an administrative tool (Cyran, 2018), to applications in supply chain management (Clauson et al, 2018). Looking in particular at applications from the perspective of the properties offered by blockchain, namely security, decentralization, consensus and immutability, we can see that these different properties can be leveraged by health informatics applications across a variety of use cases.…”

Data providers holding sensitive medical data often need to exchange data pertaining to patients for whom they hold particular data. This involves requesting information from other providers to augment the data they hold. However, revealing the superset of identifiers for which a provider requires information can, in itself, leak sensitive private data. Data linkage services exist to facilitate the exchange of anonymized identifiers between data providers. Reliance on third parties to provide these services still raises issues around the trust, privacy and security of such implementations. The rise and use of blockchain and distributed ledger technologies over the last decade has, alongside innovation and disruption in the financial sphere, also brought to the fore and refined the use of associated privacy-preserving cryptographic protocols and techniques. These techniques are now being adopted and used in fields removed from the original financial use cases. In this paper we present a combination of a blockchain-native auditing and trust-enabling environment alongside a query exchange protocol. This allows the exchange of sets of patient identifiers between data providers in such a way that only identifiers lying in the intersection of sets of identifiers are revealed and shared, allowing further secure and privacy-preserving exchange of medical information to be carried out between the two parties. We present the design and implementation of a system demonstrating the effectiveness of these exchange protocols giving a reference architecture for the implementation of such a system.
