Now, face recognition for validation

New Delhi, January 15

Aadhaar will include face recognition alongside iris or fingerprint scan as a means of verifying users, helping those who face issues in biometric authentication or have worn-out fingerprints, the authority in charge of the national identity card system said today.

The face authentication will be enabled by July to help people facing difficulty in biometric authentication due to old age, hardwork or wornout fingerprints, the Unique Identification Authority of India (UIDAI) said in a statement.

The UIDAI said face authentication would be allowed “only in fusion mode”, that is it would be valid only when used along with one more authentication feature — fingerprint or iris or one-time password (OTP).

Aadhaar, the 12-digit identifier, is being used for identity authentication across banks, telecom companies, public distribution system, income tax, amongst others.

Today’s move came within a week of UIDAI allowing residents to use a virtual ID to avoid sharing unique identity numbers when accessing government and other services in a bid to protect privacy.

Face authentication would not require any new reference data as photos of citizens are already on the database. “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,” UIDAI said.

Citing the difficulties faced by some in using the existing biometric verification mode, UIDAI said face authentication offers an additional “inclusive authentication” option.

But it emphasised that the same will be allowed “only in fusion mode” along with one more authentication factor either fingerprint, iris or OTP for successful authentication of an Aadhaar holder.

The new method will also be allowed “on a need basis”.

To facilitate the new authentication service, the Aadhaar issuing body will work with biometric device providers to integrate face modality into the registered devices.

It will also line up software development kits that will have the ability to capture face image, check liveness, and create digitally signed and encrypted authentication input. — PTI
