Open Anonymity - The Working System ->
Turing Test:
In most of the cases, you can trust the Id of
the Requester, because most of the spiders of
search engines are recognizable by this Id. For
the chicken-hearted, there is a possibility to
don't count on the right signature. This test
is to part Spiders from humans. It uses the ez-gimpy
Perl Script from the Captcha
Project to show this feature. When you can
read the text in the image beneath, there is a
high possibility that you are not a dumb computer,
maybe you are a human. This test is a quick hack,
although the script is bug-fixed a little bit,
the word in the image is passed to the check-script
via hidden value in the form(look into source
of this page). This should be implemented in a
way, that the requester can't access the word
in such simple case. Furthermore, the image should
change automatically after about 30 sec, otherwise
trained robots can pass this test with a possibility
of 80%.
