The release of more Bluetooth item finders and key finders that use a vast finder network increased the risk for stalking and location tracking on people increases. Especially the Apple AirTag and Samsung SmartTag are dangerous devices since the manufacturers updated all their Smartphones to find and report these devices. We study the prevalence of this issue and try to create applications, algorithms, and datasets to help users identify trackers and disable them.

With AirGuard, we created the first automatic tracking detection against AirTags for Android. Our project is open-source, and we continue to develop it to support other devices. If you are interested in tracking protection mechanisms innovative ways to identify all kinds of trackers and want to create software used by thousands of users, please reach out.
