Infopath 2010 & Captcha for public Sharepoint 2010 sites

I use Infopath 2010 to create forms for public Sharepoint 2010 sites and one of the requirements i开发者_开发问答s to install a Captcha check for each form.

Is this possible and if so, how?

Thank you!

I think it's not possible to use Image Captcha in infopath forms but you can use text Captcha instead. See the following link http://textcaptcha.com/

I hope that help Regards.
