The check
A quick face scan proves two things: a live person is present, and this face has not already been here for this study. Same check everywhere.
2
The single-use credential
Each verified human is handed a credential that works exactly once. This is the part that changes shape per platform.
3
The platform's own gate enforces it
We never need the platform’s permission or an integration deal, because the enforcement uses a feature the platform already ships.
What the credential looks like per platform
The strength of the lock varies a little by platform, which is exactly why we start with Alchemer: its password gate is enforced by Alchemer’s own server before a single question shows, the strongest no-code gate of any major survey tool.
Where this matters
The same gate works anywhere paid responses attract fake ones:- Academic research. Grant-funded studies where one duplicate respondent can poison a dataset, and where methods sections need a defensible answer to “how do you know they were real?”
- Market research firms. The screener criterion your clients are quietly asking about: are they a person, and are they unique?
- Panels and communities. One verified human per panelist, so incentive fraud stops at signup instead of in your data cleaning.
- Brand trackers and repeated waves. Uniqueness holds per wave while honest panelists breeze back in, so wave two fields faster and cleaner than wave one.
- B2B and expert interviews. High incentives attract professional fakers; a face that can only qualify once ends the repeat-expert problem.
