Method Of Authentication
Biometric DeviceA device which is a part of a Biometric system, that contains the sensor which captures a biometric sample from an individual.
Security measure permitting entry into a computer system only by returning a user's log-in call from a specific terminal.
Callback System
Biometric Device
To identify people by scanning their face and matching it against a library of known faces
Biometric Device
FunctionFACIAL RECOGNITION
IRIS SCANNER
To identify a person by scanning the iris or retina of their eyes.
FINGERPRINT RECOGNITION
Checking the fingerprint and measures blood flow to avoid a fake finger from being used.
Advantages And Disadvantages Of Biometric Device
ADVANTAGE DISADVANTAGE
Eliminate problems caused by lost IDs or forgotten passwords by using physiological attributes.
Injuries can lead to false biometrics.
Safe & user friendly.
Highest level of security.
Serves as a key that cannot be transferred.
Biometric devices are expensive.
Biometric devices can be hacked.
Fingerprints can be lifted off of biometrics.
Callback SystemThe callback system is commonly used in the bank operation and business transaction.Example:
when you book for the taxi service, the operator will ask you to hang up and she will call you back to confirm for the service required.
when you called a McDonald Delivery Services, the operator wil ask you to hang up since he wants to link you with the other worker.
Conclusion
