Here’s a scary story. You can track anybody’s movements through their mobile phone, all you need is five minutes access to their phone. You receive two text messages, and send one in reply, then delete the evidence, and bob’s your uncle, your target would never know. On Radio 4 today I pointed this out to one of the companies that offer this service. Their response is, essentially, that this had not occurred to them as being a problem.
I don’t get angry easily, but to my mind, this is a sinister story, and the phone companies are failing to protect your privacy, by giving away your location to anybody on the flimsiest of “consent”: one text message.
If anybody wants to take it up, write about it in the press, please email me, firstname.lastname@example.org, happy to help.
