COMMERCIAL
LABELED
Choose the document class, upload a document you believe is forged with a genuine one of the same type, box what looks altered and describe it. Passports, licenses and any identity document are refused; self-made forgeries and unpaired submissions are sent back. One pair per contributor, as PDF, from a global base strongest in Southeast Asia, the United States and Europe. Each pair gives the same document class in genuine and suspect form with a human-localized region and stated rationale, supervision forensics models cannot get from synthetic edits; DocTamper is programmatic edits, academic-only. Suspicion is the contributor's, not an examiner's; the localization is the stronger signal.
