The new Google reCAPTCHA feature can be enabled to help protect your Public Survey Links from abuse from ‘bots’, which are automated software programs that might enter trash data into your survey. A ‘captcha’ is a turing test to tell humans and bots apart. It is easy for humans to solve, but hard for bots and other malicious software to figure out. By enabling Google reCAPTCHA on your public survey, you can block automated software while helping welcome your survey participants to begin your survey with ease. The Google reCAPTCHA functionality can be enabled on the Public Survey Link page of your project, after which the Public Survey Link will display the reCAPTCHA checkbox and “I’m not a robot” text on a survey page prior to allowing the participant to view the public survey. Note: A survey participant will never have to pass the reCAPTCHA test more than once per day on a given device/computer. The new feature only works for Public Survey Links and not for custom survey links. Please contact REDCap Support with any questions.
