PREDATOR locks your PC when you are away, even if your Windows session is still opened.
It uses a regular USB flash drive as an access control device, and works as follows:
* you insert the USB drive
* you run PREDATOR (autostart with Windows is possible)
* you do your work...
* when you're away from your PC, you simply remove the USB drive:
once it is removed, the keyboard and mouse are disabled and the screen darkens
* when you return back to your PC, you put the USB flash drive in place:
keyboard and mouse are immediately released, and the display is restored.
Why aren't all these government agencies carrying around your data on their laptops not using this or a similar system?
