I nearly always walk around with a 3-d accelerometer which can indeed "phone" home.

Here's the ML extraction mechanism as explained by a Samsung engineer - http://www.slideshare.net/satnam74/the-fifth-elephant-2013-t...

Yeah but if they have access to your phone, they already know where you are, no need for the overcomplicated accelerometer method.

If it's in a database, then people without access to your phone can still identify you.
