- Face recognition won't need any new reference data
- Will only work when coupled with another authentication factor
- Camera already available to capture face without additional hardware
Face authentication will be enabled by July to help people facing any difficulty in the authentication of their fingerprints, which may be worn out because of age or hard work, or other factors, said the UIDAI or Unique Identification Authority of India.
This will not require any new data as photos of citizens are already on the Aadhaar database. But the face recognition tool will be used only if needed, along with at least one other security check like a fingerprint, iris scan or OTP number.
The photos of almost 1.2 billion people are already in the database. For verification, an Aadhaar beneficiary's face will be scanned, for which the biometric devices in use will be equipped with face recognition. The systems "will be able to capture the face image and create digitally signed, encrypted authentification inputs," said the Aadhaar agency, pointing out that in cameras in laptops and mobiles, face capture is feasible without any extra hardware.
But critics say this may add another chunk of logistical problems to the world's largest biometric database, which is already facing doubts about data security.
Around 119 crore people have been issued Aadhaar cards so far.
The UIDAI said the Aadhaar system is being used as the main Id verification mechanism by banks, telecom companies, fair price shops, Income Tax and for attendance in private companies.
