一般来说，网络，特别是苹果的“查找我的”网络，如果这些网络被滥用于跟踪，可能会对用户的隐私甚至健康构成严重威胁。苹果发布的AirTag-一个非常实惠的跟踪器，几乎无处不在的Find My网络覆盖-放大了这个问题。虽然苹果在其生态系统中提供了跟踪检测功能，但数十亿Android用户仍然被蒙在鼓里。苹果最近发布了Android应用程序“跟踪检测”，它没有提供一个令人信服的跟踪保护功能集。我们对苹果在iOS中的跟踪保护进行逆向工程，并讨论其关于跟踪检测的功能。我们设计了“AirGuard”，并将其作为Android应用程序发布，以防止Apple跟踪设备的滥用。我们比较了我们的解决方案与苹果在iOS中提供的解决方案的性能，并使用数万名活跃用户提供的数据研究了AirGuard在野外的使用情况。
Finder networks in general, and Apple's Find My network in particular, can pose a grave threat to users' privacy and even health if these networks are abused for stalking. Apple's release of the AirTag-a very affordable tracker covered by the nearly ubiquitous Find My network-amplified this issue. While Apple provides a stalking detection feature within its ecosystem, billions of Android users are still left in the dark. Apple recently released the Android app "Tracker Detect," which does not deliver a convincing feature set for stalking protection. We reverse engineer Apple's tracking protection in iOS and discuss its features regarding stalking detection. We design "AirGuard" and release it as an Android app to protect against abuse by Apple tracking devices. We compare the performance of our solution with the Apple-provided one in iOS and study the use of AirGuard in the wild over multiple weeks using data contributed by tens of thousands of active users.
