This new feature for the iPhone and other Apple products will alert you if you're being stalked.
Apple is set to release a new tracking device called Apple AirTags, which will allow Apple users to tag their devices and track them in the event if they get lost or stolen. The AirTags will sync with the Find My iPhone app, so users know exactly where their devices are at all times, and whether or not to report them stolen.
Furthermore, the Apple AirTags will be able to connect with another Apple users device and share limited information, such as a mobile number, so one could contact the owner of a lost device.
This will only work if the owner has reported the device missing. If the owner fails to do so, there is a high possibility of someone else using the lost device, such as the Apple AirPods, and can listen in to the owner's private data.
Because of this concern, Apple is releasing a new feature that will be able to detect whether or not someone else is using your lost device, and send you a warning if they are being stalked, or spied on.
