?– Perspective: Is CardSpace an Effective Tool for CAPTCHA?
Websites commonly employ CAPTCHA (Completely Automated Public Turing
Test to Tell Computers and Humans Apart) mechanisms to combat spammers,
fraudsters, and the other hordes of automated-tool-wielding barbarians.
CardSpace does provide an interface where users are required to take steps to
produce a token that the website can use.
A website employing JavaScript to engage the Identity Selector could potentially
use CardSpace to prove the existence of a human on the other side of the wire.
Although it would be possible to build a tool to automatically generate tokens
that a website is looking for, it would be a large task to perform the XML creation,
signing, and encryption.
