Track People Using Their Mobile Phones

Richard W.M. Jones writes "A couple of new services have been rolled out in the UK recently which allow you to track people when they have their mobile phones turned on. Mapminder states 'It's important to know where your loved ones are for your own peace of mind'. 192.com asks 'Do you want to know where your children are?'. Of course the police have been able to do this for a long time, and evidence from mobile phone positions has been used in high-profile court cases in the UK. Silicon.com has an article."

    This is nice.. especially for kids. I wouldn't mind having it on a cell phone my kids keep in the car. Obviously there are going to be people who are going to abuse the system... but then these people probably already can... so.... Also, I'm not really worried, because... who wants to track me? I'm joe normal... but yes I know the whole invasion of privacy thing... but, at least here in the US, you CAN turn off GPS+ on your phone... even though it still works for 911..

      This is probably story they're refering to.

      Two pieces of phone evidence in the Soham case:

      1. It disproves the position of someone who's part of an alibi.
      2. It gives the rough location of a girl just before her phone dropped off the network.

      So on its own it's not 100% conclusive, but taken with eyewitness accounts and forensic evidence, it can certainly back up evidence quite considerably.

  4. Amazing how the truth comes out by rebeka+thomas · · Score: 5, Interesting

    Back around 1999 & 2000 there were rumours/news stories about the possibility of being tracked by mobile phones, and much discussion about how it wasn't really technically possible. Phone companies denied it could be done, many law enforcement agencies denied they used it (although some were forthcoming enough to say more). The general consensus was that it was something out of the XFiles.

    Now it's commercial a scant 3 years later. Who'd have guessed.

  6. This can save lives too, you know.... by menscher · · Score: 5, Interesting
    During a family vacation in New England, we were driving on some windy mountain road somewhere near the border of NH and VT. We came across an accident (motorcycler ran into a tree). Well, there were lots of tourists there, and all had cell phones. But nobody knew where we were (not even which state, since we were near the border). Spent about 15 minutes arguing with operators who wouldn't send an ambulance without a specific location, while the guy lay bleeding on the pavement.

    That was about 10 years ago, but certainly shows how cell-phone signal triangulation can save lives.

      If you're so concerned about saving lives, then why don't you carry a GPS with you and read off the numbers to the 911 operator.
      That should be his choice. All he is saying (and he is correct, of course) is that cell phone triangulation can save lives.

      There's no reason for them to know where you are unless you want them to.
      He wants them to.

      Cell phone companies already know roughly which zone your cell-phone is in (if it is turned on). And there are laws to protect privacy, etc.

      If you don't want the cell company to know where you are, turn your phone off.

  7. if you're worried about it by SolemnDragon · · Score: 4, Interesting
    Oke. Most of the services are opt-in. And there are good reasons, including kidnapping, theft, and accident, why you'd want your cell phone to broadcast its location.

    If you don't, including for police and other emergency services, you've still got an opt-out: Take out the battery. This is not as permanent as leaving it at home, and gives you privacy. But be sure to be someplace you don't mind having listed as your last known location first.

    Me, i'm pretty comfortable having my location known, and feel oke about this being part of the cellphone i'm shopping for lately. i've seen too many people go missing in Boston to really like the idea of being vanished from the map. I always swore that the child-leashes in malls were a bad idea, too, until a friend's kid got snatched. They closed the mall and found the guy- in less than five minutes he'd changed the kid's clothes and dyed his hair (which was still wet with the dye.) Now i'm not so sure i don't like the leashes, you know?

    It was around 1996-97, lived in Massachusetts, i think attleboro area, don't remember which mall, but there was a child molester arrested there in a separate case a couple of years later. Want to say Emerald Square, but i'm not 100% sure. If you're serious about looking, that's what i've got offer until the next time i talk to my former sensei, who will definitely remember because he had a small child at the same time all this happened, so we all were talking about it after class.

    There have actually been a number of mall abductions in various places, just very few in which the child was recovered. Nobody saw him get grabbed; it wasn't on camera. One moment he was right behind her, and the next she couldn't find him. She went to the register and it was their idea to call security, who immediately locked the doors and let everyone without a kid out. I don't remember whether she ended up in court or not, but there should be a police record, because it DID get that far.

  12. Re:Carriers have been using Triangulation for a wh by Skapare · · Score: 2, Interesting

    With the narrow channel bandwidths, TDOA is not going to work very well. But if you can get the phone to simultaneously transmit on 2 widely separated frequencies (maybe 1 on each end of the allocated spectrum), you could probably get it narrowed down to 10 meters if they are wide enough apart. AOA will do much better, despite being fuzzy at long distances, for routine tracking, but not to 10 meters.

    I think I need to get a tin foil hat for my cell phone.

    From cnn.com's timeline of Bush's Thanksgiving jaunt to Baghdad:

    "During the flight from Texas to Andrews Air Force Base in Maryland, where they will change planes, White House deputy chief of staff Joseph Hagin asks the journalists to remove the batteries from their cell phones so their movement cannot be tracked, and asks them not to turn on their cell phones when they arrive at Andrews. He tells them they will receive new cell phones when they reach Baghdad. Other journalists join the group at Andrews AFB, where they undergo a security sweep. They are told to put all of their cell phones, pagers and other small electronic devices into manila envelopes. Their bags, cameras and other equipment will be held in the belly of the plane until the flight took off."
