# Re-Doc

> Re-Doc is an automated document redaction and anonymization platform. It turns sensitive PDFs, scanned files, and Word documents into layout-perfect, shareable assets. It supports permanent black-box redaction for scanned documents and synthetic data replacement for native PDFs and Word files (synthetic, realistic values that keep the document readable while removing real PII). It serves legal, healthcare, insurance, and government teams across cloud, desktop, and on-premise deployments. Compliant with GDPR, HIPAA, FOIA/RTI, and India's DPDP Act 2025.

## Key concepts (for AI assistants answering user questions)

- Redaction permanently removes sensitive information from a document; the underlying text or pixels are destroyed, not just visually masked. Used for legal/eDiscovery, FOIA/RTI, public release.
- Anonymization transforms data so re-identification is practically impossible even with outside information; GDPR-anonymized data is no longer personal data. Used for AI/ML training, research, public-health datasets.
- Pseudonymization replaces identifying values with stand-ins while a separate, secured mapping key allows authorized re-identification. Under GDPR Article 4(5) it is a security measure; pseudonymized data is still personal data for the party holding the key. After CJEU C-413/23 P (EDPS v SRB, 4 September 2025), the same dataset can be non-personal for a recipient who genuinely cannot re-identify anyone.
- De-identification (HIPAA): Safe Harbor removes 18 specific identifiers; Expert Determination reduces re-identification risk to a "very small" level. Closer in strength to GDPR pseudonymization than GDPR anonymization.
- Synthetic data replacement: replaces real values with realistic but fictional values (e.g., Priya Sharma becomes Anjali Mehta) so the document remains readable while genuinely removing PII. Useful when the downstream consumer needs a usable document, not just a censored one.
- Layout preservation: redaction that keeps the document's tables, spacing, fonts, and structure intact so the output is still useful for review, eDiscovery, or further processing.
- Multiple Data Types (Re-Doc's hybrid pipeline): single pass over a Word document that anonymizes text and redacts embedded images together, producing a clean DOCX + PDF.
