LGPD Compliance: PDF Redaction Guide for Brazil

Brazil's Lei Geral de Proteção de Dados (LGPD) establishes comprehensive data protection requirements similar to the EU's GDPR. Organizations operating in Brazil must properly redact personal data from PDF documents when sharing externally, responding to data subject requests, or complying with data minimization obligations.

The Autoridade Nacional de Proteção de Dados (ANPD) oversees LGPD enforcement and has increasingly focused on digital document handling practices. Improper PDF redaction — where personal data can be recovered from supposedly redacted documents — constitutes a violation of LGPD's data security requirements.

Brazilian-specific personal data patterns include: CPF numbers (Cadastro de Pessoas Físicas), CNPJ numbers (company registration), Brazilian phone numbers (+55 format), Brazilian bank account details, RG numbers (identity card), and names following Brazilian naming conventions.

LGPD compliance steps for PDF redaction: (1) Identify all personal data including Brazilian-specific identifiers using automated detection, (2) Apply true redaction that removes text data from PDF content streams, (3) Clean document metadata that may contain personal information, (4) Maintain records of processing activities as required by Article 37, (5) Ensure local processing to comply with data transfer restrictions.
