Unfortunately all of these apps implement their own lock screen.

Update 3: After some additional research, I’ve found a number of OS X apps that can do this, including TokenLock, Keycard and HandyLock. Update 2: It appears as there is a tool called Proximity that claims to be able to do this, but I couldn’t get it to work on Yosemite.
#Pair macos to fitbit for handylock Bluetooth
Update: As pointed out by MrMid and Lennaert van Dijke, there is a tool for Linux that can lock your computer with Bluetooth proximity claled BlueProximity. Using some sort of wearable technology would clearly require more work than simple USB drive version above, but it would look a lot less suspicious and also also be a lot more convenient. Perhaps we lock the computer if the signal strength goes below a certain level. As such, we’d likely have take into account the signal strength. There are however problems with Bluetooth, as the range can get a little too good for this particular situation. If the the computer loses connection to the device, it auto-locks. However, instead of checking for a file, we would check for the proximity of the device over Bluetooth. So what can we do about this? Given the raise of wearables, there are now a ton of different options available at our disposal.įor instance, we could use a Fitbit or Pebble for the same purpose. Secondly, having such device around your wrist is going to look very suspicious (and odd). You’re also likely to accidentally drag your laptop off of your desk in an unexpected move. First and foremost, it is likely not be very comfortable to work with a strap around your wrist all day. There are a lot of issues with the approach above. (This script is clearly more meant as a proof-of-concept than for usage in a high security environment.) Using wearables System/Library/CoreServices/Menu\ Extras/nu/Contents/Resources/CGSession -suspend # Should be something like "/Volumes// on OS X. All it does is to check for the file every second, and if it is absent, it will lock the computer (assuming you’re using OS X): Here’s an example of a very primitive version of such script. you remove the USB device), the computer will lock down. With the hardware ready, we now need a daemon or similar that runs on your computer and checks for this file. The string from the bracelet must be long enough such that it isn’t in the way while you’re typing/working. Make a bracelet out of strings or a lanyard.Format your USB drive with a some random file on.All you really need is a USB stick and some strings (or lanyard) Using just things we have laying around, we should be able to design the most primitive version. Having such device would not only be useful if you’re a high profile target (like Ulbricht), but also to conveniently lock your computer in an office environment.

This got me thinking why don’t we have Dead Man’s Switches for computers? It would be very simple to create one.


The agents managed to steal the laptop out of Ulbricht’s hands and therefore prevent him from locking the computer (which presumably had full-disk encryption). For those not familiar with the matter, Ulbricht was arrested at a library in San Francisco some time ago with his laptop open. In the last few weeks, a lot of details have been disclosed around Ross Ulbricht’s arrest.
