Sharing Information for Investigations: Need to Know and De-identification
Guidance on sharing information during investigations, including need to know, de-identification, and secure communications.

Need to know and purpose limitation

Share information solely with individuals who need it to conduct or evaluate an investigation. Use the minimum sufficient data required for the purpose. Limit dissemination to authorized teams and explain the reason for each disclosure. This approach protects individuals while enabling a fair investigation.

De-identification and anonymization

When possible, remove or mask personal identifiers before sharing data with stakeholders who do not require specific identities. De-identification reduces risk of exposure while preserving the usefulness of information for analysis. Apply consistent standards for redaction and avoidance of re identification.

Confidential communications and witness handling

Use approved channels for sharing information, maintain secure communications, and avoid discussing case details in public or non controlled spaces. Treat statements from witnesses with care and protect their privacy. Record handling steps to maintain a clear, auditable trail.

Role of investigators and HR

Investigators and HR staff must follow confidentiality policies, document access, and maintain a secure chain of custody for records. They should report any unauthorized disclosures and address potential risks promptly. Regular training reinforces responsible information sharing.
