RD (Registered Device) Service
The RD Service converts a public biometric device into a "Registered" one, suitable for secure Aadhaar-based authentication.
UIDAI mandates registered devices to:
• Prevent replay attacks.
• Ensure device traceability.
• Enable secure key exchanges.
How RD Service Works:
1. Registered Device Providers (OEMs) bundle RD service software with the biometric device.
2. When a scan is done:
• Data is encrypted at the device level.
• Device info (serial no., certification status, etc.) is bundled with biometrics.
• Sent securely to Aadhaar Authentication Server.
3. Device must contact
RD Server to:
• Get updated certificates.
• Ensure compliance.
Components:
• RD Client: Runs on user’s device (desktop/mobile).
• PID Block: Securely packed biometric data, UIDAI-compliant.
Security Highlights:
• Device whitelisting.
• No reuse of biometrics.
• End-to-end encryption.
