Facial Recognition Software
NOTE:
The facial recognition software may not be available on your computer.
Using a digital image from the camera in your computer, the facial
recognition software can identify or verify your face. This is done by
comparing select facial features from the image and a facial database. On
verification of your identity, the software allows you to access your computer
without entering the password.
Using a Firewall to Secure Your Computer
Use a firewall to secure your computer from non-authorized users (hackers) or
from malicious programs, such as viruses or worms. Firewalls also help to
prevent your computer from spreading malicious programs to other
computers.
