Biometrics
WHAT IS “Biometrics”? Biometrics is the technology that uses
humans’ unique personal characteristics to identify a person. Face structureFingerprintsHand geometry
(shape of hand and finger lengths)Retina and Iris
(Eyes’ blood vessels and coloured ring in our eyes)
SignatureVein patterns in handsVoice
Some ways in which biometrics is used: Payment
E.g. ATM Iris recognition – scans a person’s eye to access the ATM account
More secure than using a debit/credit cards.Credit cards can lost
Measure body size and keep track of their body changes during training process
Passports with computer chips Impossible for face copies
Fighting crime Install the biometric program in security
cameras to detect theft’s face structure walking on the streets etc, so police can catch them.
WHAT ARE THE ADVANTAGES OF BIOMETRICS?
Increase security Quicker log in to accounts/ checking for matching of fingerprintsNo more problems about losing ID
cards or forgetting passwords Replace hard-to-remember passwords
which may be shared or observed Make it possible, automatically, to know
WHO did WHAT, WHERE and WHEN!
WHAT ARE THE POSSIBLE DRAWBACKS? Danger to owners – cutting finger off
etc. If the data of biometrics were hacked
from database , we cannot create/change a new ‘password’ – because we cannot change our fingerprints etc.
These systems are not always reliable as human beings change over time if you are ill
If you use biometrics, you are always tracked by database – privacy issues
Expensive security solution If the system fails, you cannot get
through the doors or log in to your account
