Biometrics Identification or verification of an individual based on a physical characteristic or trait.
Biometric Modes Biological Characteristics • Fingerprint • Facial Recognition • Hand Geometry • Eye (Iris & Retina) • Vein Pattern Behavioral Traits • Signature • Voice • Keystroke Dynamics
Why use Biometrics? Biometrics has No Risk of: • Forgetting it • Losing it • Getting it stolen • Getting it copied • Loaning it out • Being used by anyone else
Biometric Uses • Financial Institutes • ATM, Validation of credit and debit cards • Law Enforcement • Automated Fingerprint Identification System • Surveillance • Physical Access Control • Buildings, Airports, Hospitals, Schools • IT Security • Network-systems of organizations – Internet/Intranet • E-Commerce market :User Authentication • Consumer Market • PC Applications(Mouse, Keyboard, Laptop, etc.) • Time and Attendance Monitoring • Home Appliances (Door locks, Safes, etc.)
Biometric Marketplace (Per International Biometric Group’s Biometric Market Report 2000-2005)
Market Drivers • Real need for increased security • Traditional methods obsolete • Increased identity theft and fraud • Advances in biometric technology • Reliability and functionality • Price factors • Weak capital markets • Competitive environment • Consolidation • Industry standardization • Current Events/Emotion
Fingerprint • Measures ridges and minutiae (end, fusion, bifurcation of fingerprint data) • Used for over 100 years • Highly accurate • Small devices • Latent prints • Environmental conditions
Facial Recognition • Measures the contours and distances of the Eyes, Nose and Chin. • May also use Thermograph matching • Easy to use/Non-cooperative • Influenced by lighting and facial angles • Susceptible to spoofing with glasses, wigs, beards
Hand Geometry • Measures finger length and knuckle thickness • Intuitive Operation • Uses few minutiae points • Large Devices limit the installation possibilities.
Eye Recognition • Iris: • Measures the shape & color of the Iris • Minutiae rich • Inconvenient • Expensive • Retina: • Blood Vessel Pattern • Highly Accurate • Low public acceptance (Intrusive)
Vein Recognition • Uses an infrared camera to measure the veins on the wrist and back of the hand. • Currently impossible to copy • Large Equipment • Expensive • Uses few minutiae points
Signature Recognition • Measures the pressure and speed of stroke dynamics • Inexpensive • Intuitive Operation • Signatures may change over time • Participation must be voluntary • Low Accuracy
Voice Recognition • Measures the vibration of phoneme, syllable, words • Easy to use • Remote applications • Easy to impersonate • Influenced by health conditions • Sensitive to noise
