There are five main
considerations when evaluating biometrics for identification
and verification purposes: accuracy,
user acceptance, and mobility.
According to Morgan Keegan's "Biometric and Natural
Interface Technologies" market study, the voice
biometric is ranked number one when measured against the
criteria of accuracy, convenience, and cost.

Accuracy is most often measured by a biometric
technology's equal error rate (EER), which is the point
where the false accept percentage and false reject
percentage are equal for the system. The percentage of false
accepts to false rejects will vary from application to
application. For example, security is of primary concern in
a financial transaction. In this case, a higher percentage
of false rejections are tolerated to ensure the desired
level of security.
Many biometric technologies are considered intrusive, and
therefore, inconvenient, because they require the user to
subject a part of their body to technical scrutiny. For
example, fingerprint technology not only requires the
installation of additional hardware, but also requires the
user to place their finger on a device similar to those used
in criminal investigations.
Obviously, organizations will consider the direct cost of
integrating hardware and software. However, an assessment of
cost will require an investigation of both interoperability
with current systems and scalability. A detailed analysis that
includes ROI projections must also be evaluated.
When considering effective security measures for verifying
one's identity, user acceptance and adoption is critical. If
customers are not comfortable with the method in which they
are identified, the security measure will be avoided and
adoption will not occur in the mass market.
As more and more financial transactions occur over
wireless devices, such as cell phones and personal computing
devices, the ability to authenticate an individual's identity
from anywhere, at anytime, is vital.
