Why It Matters for AI Governance
Pseudonymization is a data protection technique that allows AI systems to process data without direct access to personal identifiers. Unlike anonymization, pseudonymized data can be re-linked to individuals when necessary for legitimate purposes.
How CrewCheck Handles This
CrewCheck's LLM gateway applies pseudonymization-related controls at the request boundary. Every AI call passes through detection, policy evaluation, and audit logging — ensuring that pseudonymization is addressed consistently across all teams and providers.
The governance dashboard provides real-time visibility into pseudonymization events, with drill-down capabilities for compliance officers and exportable evidence for auditors.
