Many web sites have problems preventing automated use or abuse of their
services. Various techniques have been used to ensure that only
human users can operate the web site, but the standard approach is a
captcha. A captcha is generally an image containing a few letters
and numbers (see Wikipedia definition).
In theory, a human user can determine the letters in the image
easily and a computer cannot. In fact, this is not true.
Automated solutions to captchas have been around for some time
and often surpass human performance!
iTuring.com has been established to provide a better human validation
service. The service will have the following features:
- Tuneable: iTuring.com
will allow clients to define a degree of certainty that they desire
(e.g. for high-volume users, it can be useful to require a higher
degree of certainty that the user is in fact a human).
- Flexible: iTuring.com
will provide a range of text-based, image-based and sound-based tests
to suit a range of users with different bandwidth and accessibility
needs. iTuring.com will also offer an extended API, beyond the
simple go/no go test that is typcially instituted at registration time
and never reconsidered.
- Win the war: iTuring.com
will provide an ever-expanding range of tests, not limited to a single
algorithm and type as most captcha solutions are.
- Continuous improvement:
iTuring.com will provide support for and encourage clients to track and
give feedback on iTuring.com's performance. Integration of all
sources of information will enable better performance in the ongoing
task of weeding out computers and robots.
