Query: Blockchain-empowered Edge Intelligence for Internet of Medical Things
  Against COVID-19   We have witnessed an unprecedented public health crisis caused by the new
coronavirus disease (COVID-19), which has severely affected medical
institutions, our common lives, and social-economic activities. This crisis
also reveals the brittleness of existing medical services, such as
over-centralization of medical resources, the hysteresis of medical services
digitalization, and weak security and privacy protection of medical data. The
integration of the Internet of Medical Things (IoMT) and blockchain is expected
to be a panacea to COVID-19 attributed to the ubiquitous presence and the
perception of IoMT as well as the enhanced security and immutability of the
blockchain. However, the synergy of IoMT and blockchain is also faced with
challenges in privacy, latency, and context-absence. The emerging edge
intelligence technologies bring opportunities to tackle these issues. In this
article, we present a blockchain-empowered edge intelligence for IoMT in
addressing the COVID-19 crisis. We first review IoMT, edge intelligence, and
blockchain in addressing the COVID-19 pandemic. We then present an architecture
of blockchain-empowered edge intelligence for IoMT after discussing the
opportunities of integrating blockchain and edge intelligence. We next offer
solutions to COVID-19 brought by blockchain-empowered edge intelligence from 1)
monitoring and tracing COVID-19 pandemic origin, 2) traceable supply chain of
injectable medicines and COVID-19 vaccines, and 3) telemedicine and remote
healthcare services. Moreover, we also discuss the challenges and open issues
in blockchain-empowered edge intelligence.
