Biometrics Definition
Biometrics is the science of verifying and establishing the identity of an individual through physiological features or behavioral traits
Examples Physical Biometrics
Fingerprint, Hand Geometry,Iris,Face Measurement Biometric Dependent on environment/interaction
Behavioral Biometrics Handwriting, Signature, Speech, Gait Performance/Temporal biometric Dependent on state of mind
Chemical Biometrics DNA, blood-glucose
Conventional Security Measures
Possession or Token Based Passport, IDs, Keys License ,Smart cards,Swipe cards, Credit Cards
Knowledge Based Username/password PIN
Combination of possession and knowledge ATM
Disadvantages of Conventional Measures Do not authenticate the user Tokens can be lost or misused Passwords can be forgotten Multiple tokens and passwords difficult to manage Repudiation
Need for biometrics Reliable authentication and authorization
Billions of dollars are lost in identity theft and fraud Common security measures authenticate the token
or password and not the user. Repudiation problems cannot be resolved even in the
face of well documented audit trails. Identity management
Managing multiple tokens, badges, usernames and passwords are cumbersome
Maintaining such personally Biometrics cannot be lost, forgotten or stolen*
Characteristics of Biometrics Universality
Each person should have the biometric Uniqueness
Any two persons should have distinctive characteristics Permanence
Characteristic should be invariant over time Collectability
Characteristic should be easy to acquire Acceptability
Is non-intrusive and accepted by a large population Non repudiation
User cannot deny having accessed the system
The Field of Biometrics Biometrics grew out of different fields
Speaker ID : Signal processing Face Recognition: Computer Vision Fingerprints : Forensics
Biometrics is the confluence of several disciplines Sensors: electrical and mechanical engineering Pattern recognition, probability and statistics Image processing and computer vision Signal processing Algorithms and databases
Uses of Biometric Systems
Physical access control Airports, Banks, Industry
Logical access control Computer/network logon, e-commerce
Preventing identity fraud Social security (double dipping), Immigration, Border
Control Information assurance
Audit trails, Biometric cryptography protocols Securing pervasive environments
Aspects of a Biometric Systems
