Digital Contact Tracing Solutions: Promises, Pitfalls and Challenges. (arXiv:2202.06698v2 [cs.CR] UPDATED)

The COVID-19 pandemic has caused many countries to deploy novel digital
contact tracing (DCT) systems to boost the efficiency of manual tracing of
infection chains. In this paper, we systematically analyze DCT solutions and
categorize them based on their design approaches and architectures. We analyze
them with regard to effectiveness, security, privacy, and ethical aspects and
compare prominent solutions with regard to these requirements. In particular,
we discuss the shortcomings of the Google and Apple Exposure Notification API
(GAEN) that …
