To minimize amount of displayed information available for eavesdropping, PrivateEye Pro 1.0 uses web camera to determine when user is not looking at display and blurs contents of monitor to point where 
typical text is illegible. In Boss mode, program displays screen capture of user's choice when they are looking away. Eavesdropper Warnings let user see who is behind them and let eavesdroppers see that they have been caught. (more) (video)
