The technology component of this process has gained traction recently due to the prevalence of smartphones and the presence of Bluetooth LE (Low Energy) in these phones. The technology component adds agility and scalability to manual effort by logging proximity information and identifying potential subjects. Every smartphone can record the identity of other smartphones that have come in its proximity using Apps and other services. A positively tested patient’s smartphone log is used to find the other smartphone users who were in the proximity of the infected subject recently. Once identified, the people in the group are contacted for testing. This needs to be done without compromising the privacy of any of these subjects, without revealing the location and other private information that are sensitive. In all possibility, we will be seeing many more applications based on such proximity data. The current breed of contact tracing applications is built with Bluetooth LE technology for data gathering and complemented by secure server technology. In this paper, we evaluate two contact tracing initiatives built with Smartphone Bluetooth LE technology for their privacy and performance. We also identify the list of research and development tasks ahead of us in this emerging area based on this review.
