Biometrics

Biometrics is the study of computerized methods to identify a person by their unique physical or behavioral characteristics

Types of Biometrics

Biometrics can be Divided into two classes:

• Physiological Examples: face, fingerprint, hand geometry

and iris recognition

• Behavioral Examples: signature and voice

Application of Biometrics• Access control• Immigration checks• Police records• Customer identification, Loyalty programs• Security systems• Patient management in hospitals• Public welfare programs management• Preventing identity theft • Membership management in clubs, libraries etc.• Enterprise network security• Transaction management• Banking, ATMs

Advantages

• Unique• Increase security• No need to carry ID’s• the pattern in iris, retina or fingerprint remain

the same throughout our life.• No duplication of individuals identity (no

impersonation)

• Reduce Burden e.g. no car keys , house keys, no passwords

UID - Aadhar

• three pieces of biometric data-– Consist of individuals biometric information• finger print, iris scans and picture of face.

– Biggest implementation of biometrics in the world

Disadvantages

• False rejection• False acceptance• One password ‘ever’• Physical damage• Biometric database compromised– Corrupt matcher– Changed feature set

• Ethical issues– Personal data used for something other than its advertised

purpose.• Privacy issues– Who can access data– Misuse of personal data

• Public concern– What happens to biometric data after the intended use is over– Security of biometric data assured during transmission and

storage

Some case studies

• Biometric passports hacked – Britain• "Vietnamese researchers have cracked the

facial recognition technology used for authentication in Lenovo, Asus, and Toshiba laptops
