Computer Technician's Guide to Biometric Security Devices
By Stephen Bucaro
A biometric security device uses biological identifiers that are unique to individuals to
allow access to a computer or other electronic device. Some unique biological identifiers
are voice authentication, the iris of your eye, even face recognition. One common
biometric device is a fingerprint reader.
Some keyboards and laptop computers have built-in fingerprint readers, and there
are also USB fingerprint readers. It allows access by comparing the prospective
user's fingerprint to the one stored by the authorized user during initial setup.
The driver software should be installed before the USB fingerprint reader is connected.
After the software is installed, connect the fingerprint reader to the USB port. A
configuration screen will appear. It will require you to press your finger against the reader.
It reads the finger several times, and stores the results. After this, you can log on to
your computer, or your favorite Web sites with the press of your finger.
The benefits of a biometric security device is that the user doesn't have to
remember a username or password to access the system, and a hacker can't use
a password generating algorithm to gain access to the system. Most biometric
security devices come with an account management system which allows several
different user accounts to be configured.
