Detect tampered and forged documents in Brazil
Brazil faces document fraud across identity, financial, and employment categories. Forged CPF tax-ID cards, bank statements, and academic diplomas are common in lending, rental, and employment applications. The large population and digital-banking growth have accelerated both the volume and sophistication of document forgeries.

Frequently asked questions
How do I verify a Brazilian CPF document is real or fake?
TamperCheck analyses font rendering, metadata provenance, and compression artifacts on Brazilian tax-ID and identity documents. It runs 200+ forensic checks and returns a verdict within seconds, naming the exact field that was edited rather than a generic risk score.
Can AI detect fake Brazilian documents like bank statements and academic diplomas?
Yes. TamperCheck uses font analysis, arithmetic reconciliation, and compression artifact detection. It catches tampered bank statements, forged CPF documents, fake academic diplomas, and altered RG identity cards. Each finding is resolved to the individual field, not a document-level score.
What Brazilian documents does TamperCheck support?
TamperCheck supports Brazilian identity and financial documents alongside universal types like bank statements, passports, payslips, academic certificates, employment contracts, and utility bills. The same forensic pipeline covers all 100+ document types with no per-type setup.
What are the signs of a tampered Brazilian bank statement (extrato bancario)?
Look for inconsistent font weights across transaction lines, metadata dates that do not match the statement period, recompression artifacts around edited balance figures, and arithmetic mismatches between opening balance, transactions, and closing balance. TamperCheck automates all of these checks.
How do I verify Brazilian documents for a loan application?
