Aadhaar: How To Lock And Unlock Your Biometric Details

The Aadhaar Biometric locking system enables users to lock and temporarily unlock their biometrics

Highlights

  1. Locking system to protect privacy of users' biometric data, says UIDAI
  2. Once locked, use of biometrics for authentication restricted, it adds
  3. Mobile number registered with Aadhaar mandatory to lock/unlock data
Did you know you can lock biometrics-related information on Aadhaar? The UIDAI or Unique Identification Authority of India, which issues the 12-digit identity number based on biometrics-based data, has come out with a set of instructions on microblogging site Twitter on how you can lock this information. Biometrics are fingerprint and iris data used for authentication. Sharing the various steps in the biometrics locking process in a video, the UIDAI said: "If you do not intend to use your biometrics in near future, you can lock your biometrics." This can be done using a tool given on the UIDAI website - uidai.gov.in.

The Aadhaar Biometric locking system, provided by the UIDAI, enables users to lock and temporarily unlock their biometrics. "This is to protect privacy and confidentiality of Resident's Biometrics Data," the UIDAI added on its website. Once locked, the use of biometrics for authentication is restricted against any attempt to authenticate the biometrics, "thus preventing potential misuse", it noted.
Here's how to lock your Aadhaar biometrics, as given by the UIDAI:

Once you are on the UIDAI website - uidai.gov.in, find and click on the 'Lock/Unlock Biometrics' link under the Aadhaar Services section. This link leads to a separate page titled Lock/Unlock Biometrics'.

Enter the OTP received on your registered mobile number in the respective field and click 'Login'. "Registered Mobile Number is essential to avail this service. In case your mobile number is not registered with Aadhaar visit the nearest Enrolment Centre/Mobile Update End Point," the UIDAI said separately on its website.

You can also disable the Locked Biometrics But before that you will be required to login using your Aadhaar."
