The Aadhar card has surely become one of the most essential document for validating a person’s identity. Since it contains record of the cardholder’s biometric details, it is important to be cautious about all this information. While enrolling for Aadhar card, applicants are required to provide their fingerprints and iris scan to the government database. This biometric information is used for verification in order to avail benefits and services. Like for example, if you present your Aadhar card as an identity proof to get a new sim card connection, the telecom company would be able to access your data through your fingerprint as it authenticates your identity most quickly and saves a lot of time for KYC verification.

Procedure to lock and unlock biometric data in Aadhar:

There are certain risks involved with your biometric data being recorded in a central database because it may be misused by a wrongful person for unethical purposes of availing benefits and services on your name and identity. But thankfully the Unique Identification Authority of India or UIDAI has come up with a facility for cardholders to lock or unlock their biometric details to ensure safety of their identity. The misuse of an Aadhar card can be simply averted by locking their biometric data which is stored in the UIDAI server. Locking of the biometric data will mean that whenever anyone will try to use your biometric data to validate your identity for any purpose, the biometric data will not be demonstrated as valid and your identity will not be verified. The biometric information can be easily unlocked whenever required to be used for validation and verification purposes by the cardholder and you may lock it when the process is completed. To lock and unlock your biometric information online, follow these simple steps:

  1. Visit UIDAI (uidai.gov.in) & click on “Lock/Unlock Biometrics“.
