This is how UIDAI’s ‘Virtual ID’ for Aadhaar will work 

New Delhi, Jan 10 (IANS) The Unique Identification Authority of India (UIDAI) on Wednesday introduced ‘Virtual ID’ (VID) to safeguard Aadhaar cardholders’ data.

VID will be a 16-digit, randomly-generated number which can be used for authentication instead of the original Aadhaar number, according to UIDAI.

This is how VID works:

VID will be a temporary, revocable 16-digit random number mapped with the Aadhaar number. It will not be possible to derive Aadhaar number from VID.

“Last digit of the VID is the checksum using ‘Verhoeff’ algorithm as in Aadhaar number. There will be only one active and valid VID for an Aadhaar number at any given time,” the UIDAI said in a statement.

The “Verhoeff” algorithm is a checksum formula for error detection developed by the Dutch mathematician Jacobus Verhoeff and was first published in 1969.

Aadhaar number holder can use VID in lieu of Aadhaar number whenever authentication or KYC services are performed.
