“Apple and Google deliver support for unwanted tracking alerts in iOS and Android”
“With this new capability, users will now get an ‘[Item] Found Moving With You’ alert on their device if an unknown Bluetooth tracking device is seen moving with them over time, regardless of the platform the device is paired with.
…
"If a user gets such an alert on their iOS device, it means that someone else’s AirTag, Find My accessory, or other industry specification-compatible Bluetooth tracker is moving with them.”
I’m happy to see a cross-company effort to make this work for Android users as well as iOS users. Striking the right balance between alerting a user appropriately and sending confusing messages is hard, though. In two recent cases, I saw confusing false positives. In the first, I was staying in a house for a week with a team of co-workers. We all got warnings that each others’ AirTags were seen with us for too long, and some of the less tech savvy members of the team were alerted that unknown AirTags had been near them for too long, which concerned them. Of course it was true: I had AirTags in my own bags (as did others in the group), and we’d all been together for a long enough time to trigger the warning. In the next incident, I was on a long international flight, and personally got over a dozen such notifications, I’m sure triggered by all the fellow passengers who’d put AirTags in their luggage and been traveling near me for hours.
I’m worried that such false positives will lessen the impact of the messages in the case of a real, maliciously planted tracker, but I don’t have a good solution.
