FAQ
Frequently Asked Questions
Is redacted copy paste text the same as a real redaction?
No. Copy-paste characters like ▮▮▮ or █████ are decorative Unicode symbols. They imitate the look of a redaction but provide no data protection. Real redaction permanently removes the underlying text from the file, applies an opaque overlay, and records the action in an audit log. If you can copy the "redacted" text and paste it elsewhere as readable content, it was never redacted.
How do you redact text properly in a PDF?
Use the dedicated redaction tool inside a real PDF editor, not the drawing or highlight tools. Apply the redaction (which strips the text layer), then save and flatten the file. Better yet, use redaction software that handles bulk PDFs, supports OCR for scanned content, and logs every action. The biggest failure mode is saving with the underlying text still selectable.
What information do I have to redact under U.S. law?
Different statutes apply different rules. FOIA (5 U.S.C. 552(b)) defines nine exemption categories for federal records. HIPAA (45 CFR 164.514) lists 18 identifiers that must be removed from protected health information. FERPA (20 U.S.C. 1232g) protects student education records. State open-records laws add more. The right baseline is to redact all direct PII, financial identifiers, PHI where applicable, and any data that could re-identify a person in combination with public datasets.
Why did the Paul Manafort court filing leak after it was "redacted"?
The lawyers applied black highlighting over the sensitive passages without removing the underlying text layer. When journalists copied the visible black bars and pasted them into a plain-text editor, the original content appeared. It's the most famous example of cosmetic redaction failing in a high-stakes filing, and it's why courts now require defensible, software-applied redaction for sensitive submissions.
Can AI redaction tools handle audio and video, or just text?
Modern AI redaction tools handle all of it. For audio, they transcribe speech, diarize speakers, identify spoken PII like names and account numbers, and apply mute or bleep effects. For video, they detect faces, license plates, screens, and other sensitive objects, then apply blur or black-box overlays across every frame. The same platform that redacts a contract can redact a body camera recording, which is essential for FOIA and discovery workflows that mix formats.
How long does it take to redact a typical document with software versus manually?
Manual redaction of a 50-page legal document with multiple PII fields commonly takes a paralegal two to four hours. The same document processed through AI-assisted redaction software runs in minutes for the auto-detection pass, plus 15 to 30 minutes of human review and approval. Across a full FOIA backlog, the difference compounds into thousands of analyst hours saved per year.
Does redaction software work for non-English documents?
The good tools do. Look for platforms that support contextual PII detection across multiple languages, including Perso-Arabic scripts (Arabic, Farsi, Urdu) and country-specific identifiers (UK NHS numbers, Canadian SIN, EU tax IDs, Indian Aadhaar). VIDIZMO Redactor supports 82 languages for transcription and applies PII patterns tuned to country-specific formats, which matters for any organization handling cross-border records.
