HONEST COMPARISON
Most survey-fraud tools are device-fingerprint or behavioral screeners — good at spotting a suspicious device or behavior, but they never confirm a unique, present person. The vendors that do are biometric — and of those, VerifyHuman is the one that runs the face check on the respondent's own device, so no image is ever sent to a server.

Compiled from each vendor's public materials, May 2026. RelevantID = Imperium (device fingerprinting); Research Defender = Rep Data (device + behavioral + open-end NLP; no biometrics); Sentry = CloudResearch (behavioral + DigiPrint device ID); CleanID = OpinionRoute (device / network); Roundtable = behavioral proof-of-human; Verisoul = server-side face match (uploads and stores a selfie photo + video for up to 3 years). Vendors' own accuracy figures are their claims, not independent tests. Spot something wrong? Tell us — we'll fix it.
