What is Biometrics ?

• Biometrics is the science and technology of
  measuring and analyzing biological data. In
  information technology, biometrics refers to
  technologies that measure and analyze human body
  characteristics, such as fingerprints, eye
  retinas and irises, voice patterns, facial
  patterns and hand measurements, for
  authentication purposes.

Why am I so intresting in biometrics

• Social Request
• Personal interest

Benefits

• Easiest possible method of employee clock-in
  and clock-out
• Convenient - there is no password to forget,
  no card to lose
• Cost effective - there is a reduction in
  costs as there is no need for password
  administration, user up time or user support
• Protects the privacy and confidentiality of
  one's own data as a useful personal PIN can only
  be used by a particular individual

Problems/issues

• Operational 1. Recognition errors
• the false accept rate (FAR)
• A False Accept is when a nonmatching pair of
  biometric data is wrongly accepted as a match by
  the system.
• the false reject rate (FRR)
• A False Reject is when a matching pair of
  biometric data is wrongly rejected by the system.

2.Compromised biometric data

• The greatest strength of biometrics is at the
  same time its greatest liability. It is the fact
  that an individual's biometric data does not
  change over time the pattern in your iris,
  retina or palm vein remain the same throughout
  your life. Unfortunately, this means that should
  a set of biometric data be compromised, it is
  compromised forever. The user only has a limited
  number of biometric features (one face, two
  hands, ten fingers, two eyes). For authentication
  systems based on physical tokens such as keys and
  badges, a compromised token can be easily
  canceled and the user can be assigned a new
  token. Similarly, user IDs and passwords can be
  changed as often as required. But if the
  biometric data are compromised, the user may
  quickly run out of biometric features to be used
  for authentication.

3.Vulnerable points of a biometric system

• 4.Attacks

Social issue

• People could cut your hand for robbing your
  money instead of stealing your card.
• people fell really unsafe
  in the society.They have to worry about their
  personal body information(fingerprinter) being
  stored all the time.
