Risk and Architecture factors in Digital Exposure Notification

Archanaa S. Krishnan and Yaling Yang and Patrick Schaumont

Abstract: To effectively trace the infection spread in a pandemic, a large number of manual contact tracers are required to reach out to all possible contacts of infected users. Exposure notification, a.k.a. digital contact tracing, can supplement manual contact tracing to ease the burden on manual tracers and to digitally obtain accurate contact information. We review the state-of-the-art solutions that offer security and privacy-friendly design. We study the role of policies and decision making to implement exposure notification and to protect user privacy. We then study how risk emerges in security, privacy, architecture, and technology aspects of exposure notification systems, and we wrap up with a discussion on architecture aspects to support these solutions.

Category / Keywords: applications / COVID-19, exposure notification, risks, security and privacy friendly architecture
