- Bluetooth proximity tracing: Our CPSIoTSec 2020 paper on Bluetooth proximity data. We conducted a measurement study and collected traces of Bluetooth advertisements from 49 students on Purdue campus over a period of two weeks in Feb-Mar, 2019. The participating users were asked to install an Android app written by us, which periodically collected and uploaded traces of Bluetooth advertisements and device locations.
