The program director asked for an outcomes dossier by noon showing 30 clients' treatment trajectories, but we must avoid any re-identifiable details. I'm anxious about missing indirect identifiers like combined dates or locations. Take the dataset columns I attach, find every direct and indirect identifier, tell me what to remove or generalize, and produce a short anonymization checklist I can apply before sending.

How to do it

the tool · the steps · what to avoid
  1. 1

    Open the PDF you want to redact in Adobe Acrobat Pro.

  5. 5

    Choose the location to search (e.g., current document or all PDFs in a folder), then click Search.

  6. 6

    Review the search results and check all instances you want to redact, or use Select All to mark every occurrence.

  7. 7

    Click Mark for Redaction to mark the selected instances.

    Best practiceAlways double-check your search term and results to ensure all sensitive information is covered, especially with patterns like SSNs.

  9. 9

    Save the redacted PDF with a new file name.

You can use the Find Text and Redact feature to quickly locate and mark all instances of sensitive words or patterns for redaction throughout your document.

FAQ

about this task
  1. After you apply redaction marks, Acrobat will ask if you want to sanitize the document. Say 'yes'.
  2. If you missed this step, go to 'All tools > Protect a PDF > Remove Hidden Information'.
  3. This removes things like metadata, comments, and attachments that might still contain sensitive data.

Redacting permanently removes the information, making it unrecoverable. Just covering content, like drawing a black rectangle, only hides it visually. Someone can still copy and paste the text or look at the document's layers to find the hidden information, which can lead to serious privacy breaches.

For many items like Social Security Numbers (SSNs) or account numbers, use Acrobat's pattern-based auto-redaction. Go to 'Redact a PDF', then look for options to 'Find Text & Redact'. You can search for specific patterns (like SSN formats) and redact them all at once. After, have a colleague check a few random pages to make sure it worked correctly.

No, you cannot use the Adobe PDF Services API for redaction. Redaction is a feature only available in the desktop version of Adobe Acrobat Pro. There is no API operation for this specific task.

Redaction codes are labels you can apply to redacted areas to explain why content was removed (e.g., 'Privacy', 'Confidential', 'PII'). This helps others understand the reason for the redaction without seeing the actual content. You can create and edit these code sets in Acrobat. Using a consistent list of codes across your team makes it easier to manage and review redacted documents.
