5. Ajax Stylish Captcha and Contact Form using JQuery and PHP
6. Ajax Fancy Captcha
Ajax Fancy Captcha is a jQuery plugin that helps you protect your web pages from bots and spammers. Captcha’s security level is medium, with the emphasis on nice looking and user friendly qualities while still offering reasonable protection from unwanted “guests”.
7. jQuery Real Person
This plugin is designed to help overcome automated form submission by requiring a “real person” to identify text made up of dots. The entered value is compared on the server with the generated value to determine whether processing should continue.
