India's UIDAI has unveiled a beta version of a 'Virtual ID' that can be taken in lieu of Aadhaar number. The new feature will allow Aadhaar holders to quote their Virtual ID (VID) number without actually disclosing the 12-digit Aadhaar number for authentication or verification purposes. In the beta form, users can generate their Virtual ID and use it to update address in Aadhaar online for the time being, according to UIDAI which announced the Virtual ID concept earlier this year to address privacy concerns. The VID, which is a random 16-digit number mapped to a person's Aadhaar number, together with biometrics of the user would give any authorised agency like a mobile company, limited details such as name, address and photograph, which are enough for any verification. The VID effectively gives the users, the option of not sharing Aadhaar number at the time of authentication. UIDAI had stated that it will be compulsory for all agencies that undertake authentication to accept the Virtual ID.
