How To Lock Unlock Aadhaar Biometric Data Online?

The Aadhaar card has established itself as one of the main documents for proving one’s identity. However, ensuring that your Aadhaar information is safe is crucial. This system will enable Residents to lock and temporarily unlock their bio-metrics. This is to protect privacy and confidentiality of Resident’s Bio-metrics Data.

When obtaining an Aadhaar card, individuals must provide their retinal and fingerprint scan data to the government. This bio-metric data can be utilized for verification when availing other services. For instance, if you furnish your Aadhaar as an ID proof for availing a sim card, the telecom company can access your data by using your fingerprint as doing so authenticates the ID quickly and speeds up KYC verification.

Locked Biometrics ensures the Aadhaar holder will not be able to use their Bio-metrics (fingerprints/iris) for authentications thus preventing potential misuse that is stored in UIDAI servers.

The data can be unlocked whenever required and used for verification before you lock it again. Following is a simple guide to locking or unlocking your bio-metric data online.
