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
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
8. Hand and Finger Geometry
TYPICAL SYSTEMS MEASURE DIFFERENT FEATURES:
OVERALL HAND AND FINGER WIDTH
DISTANCE BETWEEN JOINTS
BONE STRUCTURE
PRIMARILY FOR ACCESS CONTROL:
MACHINE ROOMS
OLYMPICS
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.
