Why It Matters for AI Governance
Under the DPDP Act 2023, Aadhaar numbers are classified as sensitive personal data. Any AI system processing Indian user data must detect and mask Aadhaar numbers before forwarding prompts to LLM providers like OpenAI or Anthropic.
How CrewCheck Handles This
CrewCheck's LLM gateway applies aadhaar masking-related controls at the request boundary. Every AI call passes through detection, policy evaluation, and audit logging — ensuring that aadhaar masking is addressed consistently across all teams and providers.
The governance dashboard provides real-time visibility into aadhaar masking events, with drill-down capabilities for compliance officers and exportable evidence for auditors.
