Android Phones Can Now Tell You If There's an AirTag Following You 63

Posted by BeauHD from the every-breath-you-take dept.
An anonymous reader quotes a report from Ars Technica: When Google announced that trackers would be able to tie in to its 3 billion-device Bluetooth tracking network at its Google I/O 2023 conference, it also said that it would make it easier for people to avoid being tracked by trackers they don't know about, like Apple AirTags. Now Android users will soon get these "Unknown Tracker Alerts." Based on the joint specification developed by Google and Apple, and incorporating feedback from tracker-makers like Tile and Chipolo, the alerts currently work only with AirTags, but Google says it will work with tag manufacturers to expand its coverage.

For now, if an AirTag you don't own "is separated from its owner and determined to be traveling with you," a notification will tell you this and that "the owner of the tracker can see its location." Tapping the notification brings up a map tracing back to where it was first seen traveling with you. Google notes that this location data "is always encrypted and never shared with Google." Further into the prompts, you can make the tracker play a sound, "without the owner of the tracker knowing," Google says. If you bring the tracker to the back of your phone (presumably within NFC range), some trackers may provide their serial number and information about their owner, "like the last four digits of their phone number." Google indicates it will also link to information about how to physically disable a tracker. Finally, Google is offering a manual scan feature, if you're suspicious that your Android phone isn't catching a tracker or want to see what's nearby. The alerts are rolling out through a Google Play services update to devices on Android 6.0 and above over the coming weeks. Google is working to finish the joint tracking specification "by the end of this year."

The company added: "At this time, we've made the decision to hold the rollout of the Find My Device network until Apple has implemented protections for iOS."

  • So now the AirTag is no longer usable for the purpose of tracking anything that someone wants to take away intentionally (I am not saying "stolen"). All the other person needs to do is perform a scan, and the fact that the item is tracked will be made clear.

    So what is left to track? Things that no one wants and/or have no value (but if so - why would I)?

    • Not only that, the tracker only works through the internet, so if it's a problem, then you can simply not report the location through your phone's internet. The only reason it works is because the phone telling you you're being tracked is reporting the tracker's location.

        They don't use _your_ phone's internet. Any iPhone nearby will detect it and quietly report its location. So if someone stills your things, the thief's neighbour's iPhone will happily report it.

      In principle, the AirTags were supposed to be protection again losing items, not against theft. In practice, they're tools that stalkers could use against anyone who didn't have an iPhone. Now it's against anyone who doesn't have an iPhone or an Android phone.

        Apple should have agreed this standard before releasing them, and waited for Google to add support to Android. Like Google is doing now, waiting to roll out its own compatible tags.

        I'm actually kinda annoyed that I won't be able to get Google compatible tags sooner. I expect Apple won't be in any hurry to open the market up to more competition. I was hoping to track my luggage later this year.

          I challenge that assumption. Can you describe how you'd track someone using the fact that their iPhone is reporting tag locations to the Apple Find My network? Maybe it could be done if Apple did something idiotic like share the unique identifier of the device that pinged your AirTag, but surely you can design a _protocol_ that prevents the reverse engineering you describe.

      But yes, the days of being able to use AirTags to stalk people are thankfully coming to and end. In fact anyone could already scan for AirTags with a free app anyway, it's just that most criminals didn't think to.

None of these anti-stalking enhancements being implemented by Apple or Google affect the intended use of these products in the slightest.

    Now when thieves steal something, there is now a higher chance they will go looking for an Air Tag and remove it.

    • Air tags aren't meant to be an anti-theft device to begin with. They are explicitly not for that task, as a perfect anti-theft tracker is also a perfect stalking tracker.

      • Nobody's figured out exactly what they're for, yet, but I'm betting most people bought them as anti-theft trackers.

  • There are many other options out there for tiny GPS trackers that are FAR superior to AirTags,Tile, etc, that use 4G / 5G cellular to directly report their position without having to rely on nearby iPhones. Further, they are much more accurate as they determine their own GPS position instead of merely being "nearby", which is how AirTags work sending out beacon pings that iPhones in proximity pick up.

      The massive downside to GPS trackers is battery life. A Bluetooth tracker can run for a year on a coin cell. To get a year from a GPS tracker, it would have to be a lot bulkier.

      Another issue with GPS trackers is loss of signal in buildings or in the bodies of machines like cars. Because Bluetooth trackers transmit a much stronger signal, and the receivers (phones) can be inside the building/car too, they are more reliable.

      There are actually battery-free tracking tags that reflect back energy transmitted at them. They get some use in commercial settings for asset management. I could do with some at home but they aren't available to consumers as far as I can tell.

        A bluetooth tracker needs to have something scanning for it and relaying GPS information. Not easy to achieve.

        A GPS tracker can run for many years if it doesn't have to relay real-time info, eg. If it can wake up every ten minutes to transmit its location.

        You could also get fancy and put in a SMS module and SIM card and only transmit the GPS location when you send it an SMS. That way it will be undetectable by anybody scanning for trackers.

        The only limit is your budget and size requirements.
