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

Characteristics

Behavioral characteristics are:

 Keystroke dynamics  Voice  Gait  Signature dynamics

Biometrics Process

new biometric sample is requested.

Biometric Data Collection

Transmission

No Signal Processing, Feature Extraction, Representation

Quality Sufficient?

Yes Generate Template

Database Template Match

Yes No Decision Confidence?

Fingerprint Recognition steps:

Database

Input face image

Face recognition process:

Extraction of face image Extraction of face features Positive Negative Database

Input of face image

Iris Identification Steps:

Detection of eye regions Put iris in focus Recognition of iris pattern Accept Reject

Database

Vein Recognition System:

Input of palm picture The output picture Generate veins structure Match Not match

Database

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,  the pressure exerted by the person while signing,  the variations in the speed with which different parts of the signature are written.

Biometric trait

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)

Advantages of biometrics

Disadvantages of Biometrics

Costly.

Facial imaging can also hinder accurate identifications.

Missing body part problem. False acceptances and rejections.

The scanning of eye is fearful.

The nervousness that people feel about the scanners identification.

Conclusion

Not perfect yet.

Successful applications.

Decreasing costs and increasing convenience. Increasing both privacy and identity security. The field of biometrics is evolving. Benefit from this technology .
