BlueProximity – GNOME Bluetooth device distance detection and automatic locking tool :-): What a great idea. Of course, I keep my cell phone on my desk or in my coat pocket half the time, so I’m still screwed.

This software helps you add a little more security to your desktop. It does so by detecting one of your bluetooth devices, most likely your mobile phone, and keeping track of its distance. If you move away from your computer and the distance is above a certain level (no measurement in meters is possible) for a given time, it automatically locks your desktop (or starts any other shell command you want).



  1. There’s a device you can get for a windows of that plugs into your USB port. You carry a little dongle in your pocket, and when you walk away from your computer it locks. When you return it unlocks.

    You can find it on (on my mobile, so I can’t give a direct link).

  2. Hi there,

    hey – at least it would save your a** half the time :-) Hey Adam, I once saw that or a similar device on thinkgeek and came to the idea that the problem should be solved without additional hardware. BlueProximity is the result. :-)

    Have fun using it, be sure to read the open forum on sourceforge as I am hoping other people describe their uses. Since the locking/unlocking commands can be changed to whatever you like there are very interesting uses appart from locking. One guy wants to make his thinkpads light blink if his boss is around :-) NOw that is creative :-)

    Bye Lars
