Aadhaar privacy! Now, get full control of biometric data, use when you want – Here’s how
Worried about Aadhaar card privacy? Stop. The Unique Identification Authority of India (UIDAI) offers a feature that allows you to lock, or unlock, your Aadhaar number whenever you wish! Once you lock the Aadhaar number, any authentication using your Aadhaar number will not be allowed. In other words, the new feature will effectively end your privacy concerns w.r.t. Aadhaar card. Once you have locked the Aadhaar number, it can’t be used for authentication services through OTP, biometric, demographics etc. Even after locking Aadhaar, you would be able to use it, whenever you want, to authenticate yourself for KYC purposes. For this, you can use the Virtual ID (VID), which is a 16-digit random number issued by UIDAI. It can be used in place of Aadhaar number to keep your private biometric data safe.
The official UIDAI website says, “VID is a temporary, revocable 16-digit random number mapped with the Aadhaar number. VID can be used in lieu of Aadhaar number whenever authentication or e-KYC services are performed. Authentication may be performed using VID in a manner similar to using Aadhaar number. It is not possible to derive Aadhaar number from VID.”
However, before you can use your original Aadhaar number after having locked it, you will have to unlock it first.
Before locking your Aadhaar number, you must generate your Virtual ID from the UIDAI website or through SMS. For generating Virtual ID through SMS, your mobile number should be registered with the UIDAI.
