The Survey Integrity Crisis
Market research agencies, public policy researchers, and enterprise business developers struggle with a universal problem: field surveyors filling questionnaires in batches at home or faking interview responses.
Traditional survey forms do not stop fraud. GROVA introduces operational constraints directly into the capture device:
- Speed anomaly detection — an enumerator completing a 25-question interview in 45 seconds is instantly flagged.
- GPS lock requirement — questions cannot be answered unless the surveyor is physically present inside the designated census block or merchant pin.
- Respondent phone OTP — optional independent confirmation where respondents verify their participation via SMS code.
- Device fingerprinting — preventing one phone from submitting hundreds of surveys under different surveyor IDs.
Survey Verification Controls
Measures time spent per section and per question. Flags robotic or hurried responses that fail realistic reading velocity thresholds.
Send a one-time passcode to the respondent's mobile number. Verification records both the time sent and delivery confirmation.
Map polygons constrain enumerator territory. Captures outside the assigned administrative ward or village boundary require supervisor override.
Detects verbatim responses copied across different respondents or identical phone numbers entered with minor typos.
