Query: Adding Location and Global Context to the Google/Apple Exposure
  Notification Bluetooth API   Contact tracing requires a strong understanding of the context of a user, and
location with other sensory data could provide a context for any infection
encounter. Although Bluetooth technology gives a good insight into the
proximity aspect of an encounter, it does not provide any location context
related to it which helps to make better decisions. Using the ideas presented
in this paper, one shall be able to obtain this valuable information that could
address the problem of false-positive and false-negative to a certain extent.
All of this within the purview of Google/Apple Exposure Notification (GAEN)
specification, while preserving complete user privacy. There are four ways of
propagating context between any two users. Two such methods allow private
location logging, without revealing the location history within an app. The
other two are encryption-based methods. The first encryption method is a
variant of Apple's FindMy protocol, that allows nearby Apple devices to capture
the GPS location of a lost Apple device. The second encryption is a minor
modification of the existing GAEN protocol so that global context is available
to a healthy phone only when it is exposed - this is a better option
comparatively. It will still be the role of Public Health smartphone app to
decide, on how to use the location-time context, to build a full-fledged
contact tracing and public health solution. Lastly, we highlight the benefits
and potential privacy issues with each of these context propagation methods
proposed here.
