My web site has a database lookup; filling out a CAPTCHA gives you 5 minutes of lookup time. There is also some custom code to detect any automated scripts. I do this as I don't want someone data mining my site.
The problem is that Google does not see the lookup results when it crawls my site. If someone is searching for a string that i...

I do the web page for my local library, and I was thinking it might be kind of appealing to have a "custom" captcha based on book covers. So serve up one of several dozen book covers, and have the patron filling out the form type the book title to prove they're human. Assuming I stripped the title/author info from the image and filename,...
In a recent project I put a captcha test on a login form, in order to stop possible brute force attacks.
The immediate reaction of other coworkers was a request to remove it, saying that it was inapropiate for that purpose, and that it was quite exotic to see a captcha in that place.
I've seen captcha images on signup, contact, passwor...

I created a captcha just now, and it works PERFECTLY on my own server. On the school's server, it doesn't generate an image. Why might this be? The difference in code is one line.
Edit: Originally, it was working, but I deleted the directory by mistake and I do not know why did it suddenly work in the first place.
Update: I var_dumped(...
I can't figure out how to make it so the form wont fire unless the realPerson captcha is "valid". I can see that when the user types in the correct/valid letters and clicks submit it adds a class of "valid" to the input. So Ive been trying to figure out how to get the jquery.validate plugin to only fire when the class "valid" is presen...

I understand the idea of generating a form token and storing it in a session, and also putting it as a hidden input in my forms.
But how could I make this work if I have pages with multiple forms, is it still safe to use the same token for each form?
And I still feel weary about bots and stuff on my website, can these form tokens reall...

I have created a captcha which looks like this:
<img src="/cgi-bin/rand.pl" />
The problem is that if someone navigates away from or back to the page with the captcha on it, it doesn't refresh which makes the captcha invalid (especially if they have already submitted the form before) Is there anyway to force a refresh as I suspect set...
