Now days when you register on any site, they ask you to enter the character that appear in a image.for eg if you register your self on craiglist https://accounts.craigslist.org/login/signup you have to enter verification word. Any idea how can we do that on jsp/jsf website ?
As I'd mentioned once before, on another thread asking about CAPTCHAs, you could take a look at the web based service from Carnegie Mellon, called reCAPTCHA. It's a project aimed at digitizing books while providing the CAPTCHA feature.
