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
