PLATFORM · VERIFYHUMAN

AI-resistant respondent verification.

Multi-signal liveness combining behavioral, device, session, and biometric signals. Catches AI bots and human fraud before they enter your data — in the browser, in about five seconds, with no PII collected.

THE PROBLEM

AI bots have already broken survey-based research.

In independent testing, 99.8% of recent AI bots passed traditional attention checks — the kind every survey platform has used for a decade. CAPTCHAs are decorative. Behavioral checks are guessable. Post-hoc data cleaning catches some of it, at the cost of a 38% discard rate and weeks of doubt about which findings are real.

The verification industry hasn't caught up. AI bots are improving faster than the defenses they evade.

THE SOLUTION

AI-resistant. Pre-survey. Multi-signal.

VerifyHuman runs before a respondent answers a survey question. Pre-survey fraud prevention, not post-hoc cleaning. The signals VerifyHuman checks are the ones AI bots can't yet fake reliably — and the system updates as the threat surface changes.

Multi-signal liveness combines what each signal alone can't catch: adversarial bots that pass any single check fail when checked across four dimensions simultaneously.

WHAT GETS CHECKED

Four signals. One verdict.

Behavioral

Movement, hesitation, scroll patterns, response timing. The signals AI agents struggle to fake naturally.

Device

Device fingerprinting, hardware signals, network characteristics. The data trail every device leaves.

Session

Session continuity, prior verification history, geographic consistency. Catches the patterns that cross-survey fraud creates.

Biometric

Passive liveness checks. Selective, privacy-aware, applied where the signal is needed and the consent supports it.

COMPARISON

Traditional defenses weren't built for AI-era fraud.

CAPTCHAs and device fingerprinting catch the easy cases. Multi-signal liveness catches what they miss.
