Query: Privacy Guarantees of BLE Contact Tracing: A Case Study on COVIDWISE   Google and Apple jointly introduced a digital contact tracing technology and
an API called "exposure notification," to help health organizations and
governments with contact tracing. The technology and its interplay with
security and privacy constraints require investigation. In this study, we
examine and analyze the security, privacy, and reliability of the technology
with actual and typical scenarios (and expected typical adversary in mind), and
quite realistic use cases. We do it in the context of Virginia's COVIDWISE app.
This experimental analysis validates the properties of the system under the
above conditions, a result that seems crucial for the peace of mind of the
exposure notification technology adopting authorities, and may also help with
the system's transparency and overall user trust.
