Portable Biometrics

Since the laptop is easy to lose and is often stolen, one way to make certain
that unauthorized users cannot access your private wireless network is to ensure that they cannot access your computer in the first
place. One of the most effective methods of securing your laptop computer
is biometric technology.

Biometric devices, as shown include the following:


Fingerprint scanners

Palmprint scanners

Optical scanners (retina and iris)

Voice recognition

If you really want to make certain that nobody can access your PC or
Macintosh laptop computer, you could use biometric forms of access control
along with other security solutions such as:

Wireless smart cards

Wireless authentication mechanisms

Personal forms of identification that replace the traditional username/
password

Biometric plus VPN solutions (as described earlier in this chapter)

All of these methods combine to yield enhanced levels of authentication
and greater levels of data confidentiality.
