Facebook filed , titled “Offline Trajectories,” last week in which it proposes predicting users’ “location trajectories” – in other words, where we’re likely headed. Knowing when we’re about to hurtle into a no-WiFi-connection limbo means Facebook can “prefill” our phones with content and ads.
As Facebook described in the patent application, it would use machine learning to analyse metadata associated with users who already found themselves in whatever geographic location that you’re heading toward.
Of course, Facebook’s mobile app is one of hundreds that constantly track our location, so it’s already got a good basis to predict all those little circuits that we circle in our daily lives.
Leaving home at 08:07? Check. Hopping on the subway, where you can never get a connection? Oooh, maybe you need to have your phone pre-stuffed with content… like, say, that Spotify song you were jamming out to before you submerged. Working downtown at a hospital for 7.5 hours? Headed to the gym for your 70-minute workout? Followed by a visit to the juice bar? Check, check, check: if you’ve let your apps have access to your location data, who knows what all the advertisers, retailers, or hedge funds that have are doing with it.
The patent describes using your previous locations, plus the previously logged locations of other Facebook users – as in, people who aren’t even your Facebook friends – to predict where you’re likely to go. If you’re headed into an internet dead zone where Facebook can’t make any money off of you, Facebook could use its predictions to give itself a heads-up about the dire drop-off and make sure it prefills what otherwise would have been your content time-out.
Yet another of its patents, titled “Location Prediction Using Wireless Signals on Online Social Networks,” describes how Facebook could track the strength of Wi-Fi, Bluetooth, cellular, and near-field communication (NFC) signals in order to estimate a user’s current location and thus be able to predict where they’ll show up next.
All the better to track you with, my dear: this type of “background signal” information can serve as an alternative to GPS because, as the patent describes, it might prove to be more accurate at pinpointing us. It could also learn the category of where you’re at (at a restaurant or a gym, for example), what time the business is open, what are the hours during which it gets the most visits, and what time you tend to drop by.
What’s that, you say? You don’t want to be followed into your future? You don’t have to be. Here’s how to shake off the bloodhounds:
· Delete the mobile app from your phone entirely. You can always use Facebook in your mobile browser instead.
· Stop checking into places, and don’t add your location to your posts.
· On Android devices, you can try going to page. Do note, though, that researchers recently found that Google can track the location of anyone using some of its apps on Android or iPhone > > > , or you can turn off ads personalization through the
