Biometric locking is a service that allows an Aadhaar number holder to lock and temporarily unlock their biometrics, enhancing the privacy and security of their Aadhaar biometric data.
Here's a breakdown of what biometric locking entails:
-
Purpose: To protect an individual's biometric information (fingerprints, iris scans) associated with their Aadhaar number from potential misuse.
-
Functionality: The Aadhaar holder can enable biometric locking, which prevents authentication using their biometrics. Essentially, it renders biometric authentication impossible until the lock is removed.
-
Unlocking: The Aadhaar holder can temporarily unlock their biometrics when they need to use them for authentication purposes (e.g., verifying identity for government services, accessing benefits, etc.). After use, they can relock their biometrics.
-
Benefits:
- Increased Security: It adds an extra layer of security against fraudulent use of biometrics.
- Privacy Enhancement: Gives Aadhaar holders greater control over their biometric data.
- Reduced Risk: Minimizes the risk of biometric data being misused without the holder's knowledge or consent.
-
How it works (Simplified):
- The Aadhaar holder uses a designated service (typically online or through a mobile app) to initiate the locking process.
- The system verifies the Aadhaar holder's identity through other means (e.g., OTP sent to registered mobile number).
- Upon successful verification, the biometric data is locked. Authentication using biometrics will now fail.
- To unlock, the same process is followed. A time-limited unlocking option may be available for added convenience.
- After a period of inactivity or upon explicit relocking, the biometric data is locked again.
-
Example: Imagine someone is concerned about potential misuse of their fingerprints. They can lock their biometrics. If they need to use their fingerprint for authentication, they can unlock it temporarily, authenticate, and then relock it immediately afterwards.
-
Important Considerations:
- Ensure the phone number registered with Aadhaar is active, as OTP is typically used for authentication during locking and unlocking.
- Locking/unlocking is usually managed through the official UIDAI (Unique Identification Authority of India) portals or mobile applications.
In essence, biometric locking is a security mechanism that empowers Aadhaar holders to protect their sensitive biometric information, providing greater control and privacy.
