Any kind of captcha, even recaptcha cannot SOLVE all problems. Got some nice articles HERE (in english) and HERE (in german).

I am using an icon/javascript click-based captcha and it works nice (for the moment).

Captcha's and the like are a temporary solution. Computers become smarter and get always better in recognition.

A possible future development for Captcha's: recognize an image in a moving noise pattern (See movie (english spoken)).

Amazing!

But it's such a shame that some very brilliant minds use they brains for criminal purposes, and thus waste time of other brilliant minds who have to invent counter measures.

Imagine if they would combine their forces to use computers to find cure for cancer and other deseases...

I have a question.

This line in the config determine how many correct chars form the 2 words the user need to pass the confirmation???

"num_chars" => 4, // Maximum characters

idk, if this is a error or what?

in the begin i believe it was something wrong in my code, but i tested in this site (xoops.org) and happen this same.

If the user write the first word good, and wrong the second word the user still can register (pass the recaptcha).

So that is a normal behavior? or this a error in the code???

Edit: btw, i tested on the site http://recaptcha.net/ , and there you have to write good the 2 words to pass the recaptcha, i believe we are missing something in the code

The maximum char setting is for the normal image captcha. If you change it you can have the user to enter eg 6 characters.

The recaptcha is also partly a human OCR program to help digitalising scanned printed books. So, one word is known and verified and one word is the ocr assignment but can not always be verified.

I cannot find the package and documentation for how to implement recaptcha to XOOPS?

By the way is there any roadmap to include to the XOOPS core?

Thanks. I install as instructed. It seems to be working but there are some problems:

If you keep num_chars as 4, reCaptcha looks for first 4 letters.

So I set num_chars as 24 instead of 4, but it does not solve problems.

If first word has N letters, and if you write only first N-1 letters of first word (and it does not care of second word) than you will passed by reCaptcha. But this is not what we want.
