Guys,
     for one of our registration projects, we needed to verify that a
user is really in front of the browser (no automatons allowed). I
wrote, then, a little "text-warper" that randomly stretches text for
a user to see (and re-type) and writes out JPEG files.

In addition to that I wrote a little random-text generator and
encryptor (so that you can be sure the text displayed is nowhere in
your HTML). An example of a generated image is attached here.


Did you look at what Ugo did with captchas?

Ciao,

Yep, but SVG IMVHO is quite overkill to generate a simple image... Plus I suspect that the blurring algorithm is quite easy to recognize (in terms of running a simple image analysis package over the generated output).


I kinda like more random things! :-P :-P
