How to Prevent Misuse of Aadhaar Card

The Unique Identification Authority of India issues the 12-digit Aadhaar Number to all the residents of India which acts as the proof of identity and proof of address for availing government subsidies and benefits. The Aadhaar Number, however, is not a citizenship certificate but it is imperative to protect the security of Aadhaar and prevent the misuse of it.

In order to protect and safeguard the personal data of the citizens, the Government of India has opted for various measures, and locking and unlocking of an Aadhaar Card is one such feature. The lock/unlock Aadhaar Biometrics is a feature introduced by the UIDAI as once you lock your Aadhaar number you cannot do any authentication using your Aadhaar number and you can use the Virtual ID to do the same. Whereas, once you unlock your Aadhaar Biometrics it means that your Aadhaar Number is again active and you can do the authentication.

Using Virtual ID instead of Aadhaar Number

Aadhaar Virtual ID is a 16-digit temporary code that is generated against an Aadhaar number through the UIDAI portal and is valid until the user generates another virtual ID again. You can use the virtual ID in place of Aadhaar everywhere as it also helps in providing security to your Aadhaar Card.

This virtual ID can be generated and shared with any agency for the purpose of KYC and for authenticating your details. Moreover, once your details are verified, you can once again generate a new virtual ID in order to protect your details from someone else trying to access your personal details.

Hence, it is advised to use the virtual ID instead of your original Aadhaar number.
