The Unique Identification Authority of India (UIDAI) on Monday said it was soon going to roll out face authentication as an additional security feature for Aadhaar verification.

The new feature, likely to be introduced by July, would make it convenient for those who have difficulty in authentication through fingerprints or iris.

However, the face recognition would be used only in "fusion mode", that is it would be valid only when used along with one more authentication feature, which are fingerprint or iris or one-time password (OTP), the UIDAI said in a statement.

"The UIDAI has decided to enable face authentication in fusion mode on registered devices by July 1, 2018 so that people facing difficulty in other biometric authentication (fingerprint and iris) could easily authenticate," it said.

"This facility is going to help in inclusive authentication of those who are not able to biometrically authenticate due to their worn out fingerprints, old age or hard work conditions," it added.
