CAPTCHA

A CAPTCHA, "Completely Automated Public Turing test to tell Computers and Humans Apart", can be included in surveys to help prevent fraud by checking to see that the respondent is actually a person and not a computer program. IntelliSurvey uses reCAPTCHA for this process, which can easily be incorporated into a survey by including a pre-built library.
