Biometrics Authentication Technology

• Something you know, like a password, PIN, or code.

• Something you have, like a swipe card, smart card, token, or key.

• Something you are, which is biometrics.

Three main types of authentication available today are:

What is a biometric?

Biometrics are automated methods of identifying a person or verifying the identity of a person based on a physiological or behavioural characteristic.

Most definitive, real-time tool available today.

Can be combined with other tools to form more secure, easier to use verification solutions.

Recognizes individuals definitively.

Aadhaar

One-time standardized Aadhaar enrollment establishes uniqueness of resident via ‘biometric de-duplication’

• Only one Aadhaar number per eligible individual

Online Authentication is provided by UIDAI• Demographic Data (Name, Address, DOB, Gender)• Biometric Data (Fingerprint, Iris, Face)

Aadhaar :subject to online authentication is proof of ID

Aadhaar enrollment / Update = KYC

Aadhaar No. Issued, stored in Auth. Server

“Verification” of KYC (Authentication)
