The London Tube Is Tracking Riders with Their Phones

From Wired:

An agency like TfL could also use uber-accurate tracking data to send out real-time service updates. “If no passengers are using a particular stairway, it could alert TfL that there’s something wrong with the stairway—a missing step or a scary person,” Kaufman says. (Send emergency services stat.)

The Underground won’t exactly know what it can do with this data until it starts crunching the numbers. That will take a few months. Meanwhile, TfL has set about quelling a mini-privacy panic—if riders don’t want to share data with the agency, Sager Weinstein recommends shutting off your mobile device’s Wi-Fi.

So, on the one hand, they’ll apply norms and biases to ascertain why their data ‘says’ certain things. But to draw these conclusion the London transit authority will collect information from customers and the only way to disable this collection is to reduce the functionality of your device when you’re in a public space. Sounds like a recipe for great consensual collection of data and subsequent data ‘analysis’.
