Document or PDF redaction is the process of permanently removing sensitive or confidential information such as names, addresses, Social Security numbers, or financial data from digital or scanned documents before sharing them. Modern document redaction software like CaseGuard uses AI to automatically detect and redact personally identifiable information (PII), protected health information (PHI), and other private data to maintain privacy and comply with laws such as HIPAA, GDPR, and FOIA.

Effective document redaction goes beyond simply hiding text. It ensures sensitive information is permanently removed and unrecoverable. Here are the key best practices:

• Use a professional redaction software instead of manual methods like drawing boxes or highlights.

• Automate your redaction process using CaseGuard to reduce human error. AI tools can detect and redact PII, PHI, and other confidential data quickly.

• Redact across all content layers, including scanned text, metadata, and more.

• Review redactions before exporting to ensure nothing was missed or mistakenly removed.

• Maintain audit trails for compliance and accountability.

Common types of information that should be redacted from documents include:

• Personally Identifiable Information (PII): Names, SSNs, addresses, emails, phone numbers, emails, and more

• Protected Health Information (PHI): medical records, diagnoses, treatment details, and insurance data

• Financial Data: Bank account numbers, credit card details, income, tax information

• Legal and Investigative Information: Case numbers, witness names, victim information, and attorney client communications

• Metadata and Hidden Content

CaseGuard’s bulk redaction feature lets you redact multiple documents at the same time, automatically detecting and removing sensitive information like names, emails, phone numbers, and more.
