Detect tampered and forged documents in Nigeria
Document fraud in Nigeria spans bank statements, academic credentials, and government-issued IDs. Forged documents are used for loan applications, visa processing, and employment verification. The rise of affordable editing tools has accelerated both the volume and sophistication of tampered submissions.

Frequently asked questions
How do I verify if a Nigerian bank statement is real?
Upload the statement to TamperCheck and it runs 200+ forensic checks on font rendering, metadata consistency, and compression history. The system names the exact field that was edited - such as the closing balance or an individual transaction - rather than returning a generic risk score. Results are returned within seconds.
Can AI detect fake Nigerian documents?
Yes. TamperCheck uses a hybrid forensic and AI pipeline that analyses font weight, kerning, glyph rendering, edge sharpness, and recompression history for each OCR field. It catches smoothed and re-rendered edits that whole-image Error Level Analysis misses, across Nigerian bank statements, WAEC certificates, NIN slips, and passports.
What Nigerian documents does TamperCheck support?
TamperCheck supports Nigerian bank statements, National Identity Number slips, international passports, and academic certificates, alongside universal document types such as payslips, utility bills, invoices, and employment letters. The same forensic pipeline runs on all 100+ supported document types with no per-type setup.
What are the most common signs of a fake Nigerian document?
Look for inconsistent font weights across fields, misaligned text on official letterheads, metadata dates that do not match the document date, and recompression artifacts around edited regions. On bank statements, check that opening and closing balances reconcile with individual transactions. TamperCheck automates all of these checks.
What should I do if I suspect a Nigerian document is forged?
Upload it to TamperCheck for automated forensic analysis. The system returns an AUTHENTIC or TAMPERED verdict with specific findings tied to document regions. Share the report with the relevant authority - a lender, employer, or immigration officer - as evidence. TamperCheck charges $0.50 per document with no subscription required.
TamperCheck analyses document uploads with a hybrid forensic and AI pipeline tuned for Nigeria. Upload endpoints accept PDF and common image formats; document class is inferred automatically. See the API documentation for authentication, async jobs, and webhooks.
