India’s Unique Identification project, also known as Aadhar, earlier this week finished capturing demographic and biometric data of over half a billion residents–the largest biometric project of its kind currently in the world.
Aadhaar authentication is the process wherein Aadhaar number, along with other attributes (demographic/biometrics/OTP) is submitted to UIDAI’s Central Identities Data Repository (CIDR) for verification; the CIDR verifies whether the data submitted matches the data available in CIDR and responds with a Yes/No. No personal identity information is returned as part of the response.
Numerous nations around the globe utilize a remarkable personality framework whereby every native gets a number that hold all subtle elements related to their character under it.
