Does this tool interfere with PII?
Yes. Our solution is fully PII compliant because it is document agnostic — it doesn’t read, extract, or process the actual content or sensitive data within documents. Instead, it analyzes the structure, layout, and metadata of files to detect fraud.
By focusing on how documents are built rather than what they say, the tool preserves privacy, protects sensitive information, and reduces exposure to PII. This design helps you meet privacy regulations while effectively spotting sophisticated document forgeries in your marketplace onboarding process.
