  In this paper, we propose a global digital platform to avoid and combat
epidemics by providing relevant real-time information to support selective
lockdowns. It leverages the pervasiveness of wireless connectivity while being
trustworthy and secure. The proposed system is conceptualized to be
decentralized yet federated, based on ubiquitous public systems and active
citizen participation. Its foundations lie on the principle of informational
self-determination. We argue that only in this way it can become a trustworthy
and legitimate public good infrastructure for citizens by balancing the
asymmetry of the different hierarchical levels within the federated
organization while providing highly effective detection and guiding mitigation
measures towards graceful lockdown of the society. To exemplify the proposed
system, we choose the remote patient monitoring as use case. In which, the
integration of distributed ledger technologies with narrowband IoT technology
is evaluated considering different number of endorsed peers. An experimental
proof of concept setup is used to evaluate the performance of this integration,
in which the end-to-end latency is slightly increased when a new endorsed
element is added. However, the system reliability, privacy, and
interoperability are guaranteed. In this sense, we expect active participation
of empowered citizens to supplement the more usual top-down management of
epidemics.
