End-to-End Privacy for Open Big Data Markets
The idea of an open data market envisions the creation of a data trading
model to facilitate exchange of data between different parties in the Internet
of Things (IoT) domain. The data collected by IoT products and solutions are
expected to be traded in these markets. Data owners will collect data using IoT
products and solutions. Data consumers who are interested will negotiate with
the data owners to get access to such data. Data captured by IoT products will
allow data consumers to further understand the preferences and behaviours of
data owners and to generate additional business value using different
techniques ranging from waste reduction to personalized service offerings. In
open data markets, data consumers will be able to give back part of the
additional value generated to the data owners. However, privacy becomes a
significant issue when data that can be used to derive extremely personal
information is being traded. This paper discusses why privacy matters in the
IoT domain in general and especially in open data markets and surveys existing
privacy-preserving strategies and design techniques that can be used to
facilitate end to end privacy for open data markets. We also highlight some of
the major research challenges that need to be address in order to make the
vision of open data markets a reality through ensuring the privacy of
stakeholders.Comment: Accepted to be published in IEEE Cloud Computing Magazine: Special

Is Blockchain for Internet of Medical Things a Panacea for COVID-19 Pandemic?
The outbreak of the COVID-19 pandemic has deeply influenced the lifestyle of
the general public and the healthcare system of the society. As a promising
approach to address the emerging challenges caused by the epidemic of
infectious diseases like COVID-19, Internet of Medical Things (IoMT) deployed
in hospitals, clinics, and healthcare centers can save the diagnosis time and
improve the efficiency of medical resources though privacy and security
concerns of IoMT stall the wide adoption. In order to tackle the privacy,
security, and interoperability issues of IoMT, we propose a framework of
blockchain-enabled IoMT by introducing blockchain to incumbent IoMT systems. In
this paper, we review the benefits of this architecture and illustrate the
opportunities brought by blockchain-enabled IoMT. We also provide use cases of
blockchain-enabled IoMT on fighting against the COVID-19 pandemic, including
the prevention of infectious diseases, location sharing and contact tracing,
and the supply chain of injectable medicines. We also outline future work in
this area.Comment: 15 pages, 8 figure
