e-Commerce/Telephony is the use of biometrics to identify or verify the
identity of individuals conducting remote transactions for goods or services.
The biometric is used to complement or replace authentication mechanisms such as
passwords, PINs, and challenge and response interaction. Though there are
differences between e-Commerce and Telephony - primarily in the acquisition
technologies which enable each application - e-Commerce/Telephony is a logical
grouping for several reasons.
Both applications involve individuals remote parties, and typically lack high
degrees of trust. There is a need to establish the identity of the agents in
both e-commerce and telephony applications; without biometrics, it is difficult
to do so efficiently and reliably. Similarly, both currently lack secure
enrollment processes, such that lower degrees of certainty might be associated
with certain enrolled users.
