Core system software maker Phoenix Technologies
announced on Wednesday an add-on program for Windows XP and Vista that
links users' phones with their computers — walk away and the system
will lock automatically.
The software, dubbed Phoenix Freeze,
uses a mobile device's Bluetooth feature to pair a phone with a laptop
or desktop system. When a user moves a certain distance from the
computer, the program will lock the desktop; when the user returns, the
program will automatically unlock the system.
