RESPONDENT VERIFICATION · BY RIWI

Every respondent, a real and unique human. Privacy by design.

VerifyHuman screens every respondent for fraud invisibly — bots, click farms and repeat takers caught before the survey starts, with nothing to see and nothing to do. Where you need more proof, add a ~5-second camera check on the respondent's device that proves a live, unique person. No images. No identity. Ever.

Prove you're humanHow it works

Because at least 1 in 3 survey respondents worldwide isn't authentic.

THREE LEVELS OF PROTECTION

Silent by default. A camera only where you want one.

VerifyHuman checks for real people without interrupting them. You choose how much proof you want for each project — your respondents barely notice either way.

  • Step 01
    Silent check · Server API
    What it does

    Your server sends us each respondent and gets back Allow, Review or Block, judged on their network, device and track record. Nothing is added to the page.

    Your respondent sees

    Nothing

  • Step 02
    Silent check · On your page
    What it does

    A small script on your page also sees how the respondent behaves there and catches automated browsers — still nothing to see or do.

    Your respondent sees

    Nothing

  • Step 03
    Quick or Full camera check
    What it does

    A few seconds of camera to prove a live, unique person. Use it for a whole study, or turn on the option that lets an unsure silent check ask for it.

    Your respondent sees

    A short camera check

One platform, three levels. Start silent; add a camera check where a study needs it — or let an unsure silent check ask for one (an option, off by default) — so good respondents sail through.

How it works

It is one scoring system. A silent check on the Server API works from what your server sends us; the script on your page adds what it sees there; a camera check adds proof of a live, unique person. If you turn the option on, an unsure silent check on your page moves the respondent to a camera check.

SEE IT YOURSELF

Don't take our word for it. Prove you're human.

With a silent check, respondents never see anything. This is the Full camera check — the strongest proof, and the part a bot can't fake. Take it yourself: camera on for about five seconds, on your device. You'll see exactly what a respondent sees, then we'll show you what just happened.
