- Locking system to protect privacy of users' biometric data, says UIDAI
- Once locked, use of biometrics for authentication restricted, it adds
- Mobile number registered with Aadhaar mandatory to lock/unlock data
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.
How to disable Aadhaar Biometric Lock
For unlocking your biometrics, first login using the OTP-based method explained earlier.
Once logged in, enter the security code and then click on 'Disable' button on the next page to disable the biometric lock, according to the UIDAI website. Once the lock is enabled, the user can either unlock it (which is temporary) or disable the Locking System, it noted.
Users of the biometrics locking system are cautioned to use this facility with care to prevent denial of Authentication services, the UIDAI added.
