Cell Phones Tracking Nightlife Activity 121

Roland Piquepaille writes "A Columbia University computer science professor has co-founded a New York-based company named Sense Networks to sell tracking software to other companies. It is also distributing a free version of this software, named Citysense, which shows on your cell phone where the wild things are happening in your own town. Citysense 'uses advanced machine learning techniques to number crunch vast amounts of data emanating from thousands of cell-phones, GPS-equipped cabs and other data devices to paint live pictures of where people are gathering.' Citysense is available today in San Francisco, before being soon deployed in Chicago and five other U.S. cities."

I'm so sick and tired of reading poorly mislabeled slashdot stories that tout around the title "CELL PHONE" when the stories usually only relate to a singular brand of phone, or limited range. Not everyone owns a Blackberry, and not everyone owns the iPhone (which is supposed to be next on the list of phones with enough crap inside to support this app).

    More seriously, it appears that this technology is GPS-only and not all folks have GPS-equipped phones. I don't understand GPS all that well and I'm wondering how this tracking software can locate them, do they have to consent to being tracked, etc. This also has some scary big-brother implications if it were to move past GPS and into standard triangulation of ALL cell phones -- with or without the user's consent(well, kinda -- what percent of average Joe users actually read their EULA/cell contract/etc.), to be used for marketing purposes(or worse).

      Actually, GPS isn't required to locate you with a cell phones. The technology exists to poll which cell phone towers your phone is polling and make a guesstimate of where you are based on that.

      With cell technology, you're not simply talking to one tower at a time because if you were traveling, then as soon as you were out of range of the tower, you would have the call drop. So the cell phones are actively polling the towers as you move to hand you off between the closest (or best signal in some case).

      This is how they locate you if you call 911.

      The downside is that if you are in a rural area, and have only 1 or even two towers (it takes three to triangulate), then they can't really tell where you are other than somewhere in a radius of the tower. So this technique only works within areas with high cell tower density.

      On a side note, you could always lend your cell phone to a girl when she goes to a Chip and Dale club and let the hilarity ensue when your friends show up there.

      • While what you say is true the use of the term 'polling' is a little misleading (maybe only to me). The cell phone is continually receives all the nearest signals (its a multichannel device) and may at any time switch channels to a stronger one. Its not polling in the sense that the phone isn't opening short term connections to the nearest cell phone towers to determine signal strength, which is what I think of when I hear the word 'polling'.

    • The Government can already track every modern mobile phone out there. It was a requirement so that (ostensibly) 911 can find you if you're in trouble and call for help but can't tell them where you are. The only way to be untrackable unless you have a truly ancient phone is to turn it off, and if you're really paranoid take the battery out.

    I operate a free GPS tracking service (http://www.instamapper.com [instamapper.com]), so I know a thing or two about this topic.

    This is an interesting idea, but it won't catch on for a few more years. The problem is that only a tiny fraction of cell phones (I would estimate less than 1%) are capable of GPS tracking now. Of those people who have a compatible phone, most won't bother to install the app and remember to start it whenever they go out. Typical battery life when GPS is turned on is about 8 hours. So this is not an app that can run in the background 24/7.

    In the end, you will have something like 10 people in San Francisco who send data to their system. It is enough data to make sense of what's happening in the city? Not hardly.

    Give it another 5-10 years, and perhaps most phones will have GPSs in them. Perhaps battery life will improve enough to make continuous GPS tracking possible. Until then, this service, and other similar services, will have little value.
