Biometrics Authentication Technology

Three main types of authentication available
today are

• 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.

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.

Characteristics

• The common Physical characteristics are
• Fingerprint
• Face
• Retina
• Iris
• Vein pattern
• Hand and finger geometry

5
Characteristics

• Behavioral characteristics are
• Keystroke dynamics
• Voice
• Gait
• Signature dynamics

Signature Verification Process

• the angle at which the pen is held,

• the number of times the pen is lifted,

• the time it takes to write the entire signature,

Biometric trait

• the pressure exerted by the person while signing,

• the variations in the speed with which different
  parts of the signature are written.

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
