While UIDAI readies for a new system, called Limited KYC, to secure Aadhaar holders’ privacy, there is a way users can safeguard their data from their end, the Biometric Lock’. UIDAI has included a feature to lock your biometrics details to prevent any misuse of your Adhaar credentials.

Aadhaar biometric data includes Fingerprint and Iris impressions that you often use to authenticate your identity with banks and telecom companies, among others. For instance, the verification of mobile SIM is done by providing the unique 12-digit Aadhaar number and authenticating with your biometric data.

The new “Biometric Lock” will lock your biometric Aadhaar data to avoid anyone from accessing it without your consent. When needed, you can unlock the same and proceed with any required verification process.
