A Brief Bibliometric Analysis and Visualisation of Scopus and WoS databases on Blockchain Technology in Healthcare Domain

Background: The aim of this study is to analyse the work carried out in healthcare or medical domain using blockchain technology for privacy and security of patient’s data, their healthcare records. The documents published in Scopus and Web of Science databases during the year 2016 to present (February 2021) have been considered for survey. Methods: Scopus and Web of Science(WoS), most popular databases are used to retrieve documents which were published between years 2016 to present. Scopus analyser and web of Science analyser are used for analysis of various parameters such as documents published per year, sources of documents, number of citations and so on. VOSviewer1.6.16 software tool is used for analysis of different units such as citations, co- authorship etc. Results: During our survey we have retrieved a total 598 documents related to blockchain technology in the healthcare domain which are published from year 2016 on wards from scopus database. Using a web of science database 594 documents has been retrieved for the same domain. Statistical analysis and network analysis shows that there is tremendous growth in publications from year 2019 and 2020 on blockchain technology. The United States, India and China are major contributors. Conclusions: Databases are analysed in terms of number of documents per year, sources of publications, authors correlation, documents per country, funding agencies etc parameters are statistically analysed. Using statistical and network analysis we can conclude that there is huge scope to work in the blockchain domain to achieve more privacy, security, and data integrity

A Review on Blockchain for the Internet of Medical Things: Definitions, Challenges, Applications, and Vision

none3noNowadays, there are a lot of new mobile devices that have the potential to assist healthcare professionals when working and help to increase the well-being of the people. These devices comprise the Internet of Medical Things, but it is generally difficult for healthcare institutions to meet compliance of their systems with new medical solutions efficiently. A technology that promises the sharing of data in a trust-less scenario is the Distributed Ledger Technology through its properties of decentralization, immutability, and transparency. The Blockchain and the Internet of Medical Things can be considered as at an early stage, and the implementations successfully applying the technology are not so many. Some aspects covered by these implementations are data sharing, interoperability of systems, security of devices, the opportunity of data monetization and data ownership that will be the focus of this review.openGioele Bigini;Valerio Freschi;Emanuele LattanziBigini, Gioele; Freschi, Valerio; Lattanzi, Emanuel

A blockchain-based eHealthcare system interoperating with WBANs

Due to the increasing population of the elderly and patients with chronic diseases, more and more individuals are suffering from the limited service capabilities of the traditional medical systems. Benefiting from the rapid development of biomedical sensors, Internet of Things, and modern communication and network technologies, eHealthcare systems start appearing in the medical services, especially for the remote physical condition monitoring which improves the efficiency of the traditional medical systems. To provide a secure and low power healthcare solution, a blockchain-based eHealthcare system interoperating with wireless body area networks (WBAN) has been proposed, which utilizes the WBAN to network the devices of the patients and the blockchain technology as the data transmitting and storage method. The evaluation results show that the proposed system has the advantages of low hardware resources utilization, high-security protection level, and stable performance
