This document discusses biometrics authentication using physical and behavioral traits for security. Biometrics can identify users by their fingerprints, iris scans, facial recognition, voice patterns, and other characteristics. Popular biometric systems include fingerprint scanners, iris scans, and facial recognition. Biometric templates, which translate characteristics into codes, range in size from 9 bytes for hand geometry to 84 bytes to 2k for facial recognition. The document explores how biometric authentication works and is becoming more common for both commercial and personal use.
Biometrics authentication
- 2. What is Biometrics ? Biometrics -- technology that identifies you based on your physical or behavioral traits -- for added security. Biometrics can use physical characteristics, like your face, fingerprints, irises or veins, or behavioral characteristics like your voice, handwriting or typing rhythm.
- 3. You take basic security precautions every day -- you use a key to get into your house and log on to your computer with a username and password. You've probably also experienced the panic that comes with misplaced keys and forgotten passwords. It isn't just that you can't get what you need - if you lose your keys or jot your password on a piece of paper, someone else can find them and Can use them

- 5. Fingerprint scanners are a popular type of biometric system
- 6. Biometrics in nootbook BIOMETRIC SECURITY SYSTEMS, LIKE THE FINGERPRINT SCANNER AVAILABLE ON THE IBM THINKPAD T43 (RIGHT), IS BECOMING MORE COMMON FOR HOME USE.
- 7. the nootbook Systems also use the biometrics authentication : A sensor that detects the characteristic being used for identification A computer that reads and stores the information Software that analyzes the characteristic, translates it into a graph or code and performs the actual comparisons

- 9. Iris Scanning WHEN YOU LOOK INTO AN IRIS SCANNER, EITHER THE CAMERA FOCUSES AUTOMATICALLY OR YOU USE A MIRROR OR AUDIBLE FEEDBACK FROM THE SYSTEM TO MAKE SURE THAT YOU ARE POSITIONED CORRECTLY. USUALLY, YOUR EYE IS 3 TO 10 INCHES FROM THE CAMERA. WHEN THE CAMERA TAKES A PICTURE, THE COMPUTER LOCATES: THE CENTER OF THE PUPIL THE EDGE OF THE PUPIL THE EDGE OF THE IRIS THE EYELIDS AND EYELASHES IT THEN ANALYZES THE PATTERNS IN THE IRIS AND TRANSLATES THEM INTO A CODE.
