Our assumption is that you create surveys to collect information from humans, not computers. This is why Checkbox created the CAPTCHA item type. CAPTCHA, which stands for “Completely Automated Public Turing test to tell Computers and Humans Apart,” significantly increases survey security by preventing computer “bots” from finding and populating Checkbox surveys with false or “spammy” responses.
To include a CAPTCHA item in a survey, follow the steps below:
1. Select “Add Item”.
2. Select “CAPTCHA” from the Question Items list (note: hover over the green arrow to the left of the item description to see a preview of the item).
3. Enter desired question/sub text.
4. Configure appearance options. CAPTCHA style, code length, image size, image format, and item position can all be customized within the item editor. You can even enable sound! (Note: display multiple CAPTCHA styles in your survey by moving more than one available style options into the “Selected” box. When testing your CAPTCHA item, refresh the page to display the alternate styles).
5. Save, preview, and test your CAPTCHA item.
CAPTCHA is one of the many survey security options offered by Checkbox. Using access lists, user roles, and survey security settings, you can control who has access to not only your surveys but other entities within Checkbox, as well, such as users, folders, and question libraries.
