What is Face Authentication?

1. UIDAI uses face authentication as a process by which an Aadhaar number holder's identity can be verified. A successful face authentication confirms that your physical face which is being scanned for verification matches the one which was captured at the time of enrolment when your Aadhaar number was generated. A successful face authentication confirms that you are who you claim to be.

2. Face authentication is based on a 1:1 matching which means that the facial image captured during authentication is matched with your facial image which is stored in the Repository against your Aadhaar Number, which was captured at the time of enrolment.

3. Face authentication is consent based.
