 The
process inn which a person’s unique physical
and other traits are detected and recorded by an
electronic device or system as a means of
confirming
identity.(http://dictionary.reference.com/bro
wse/biometrics)
 Commonly used as personal clock in methods by
employers .
 In more recent times used for personal devices
such as laptops and smart phones.
 1.Iris.
 2.Finger
print.
 3 .Palm print.
 4.Facial
Recognition.
 5.Hand shape.
 6.Retina.
 7.Ear.
 8.Palm vein
Imaging.
 9.Voice.
 The
first biometrics used was fingerprint
analysis to prove criminal activity.
 In the 1970s fingerprint identification started
to be used on a large scale for personal clock
ins for large companies.
 Later palm print and hand size started to be
used for clock ins at large companies.
 Nowadays it is common practice among most
large companies to use biometric check ins
as it ensures that it is you using the machine.
 Iris
and retina is used nowadays as it is more
reliable than hand size, palm print and finger
print, due to the fact that it is far less
discriminatory.
 People who have suffered disfigurement t or
limb amputation are unable to use these
machines. It is far less likely for an individual
to be missing both eyes.
 It is also much harder to impersonate
someone else's, Iris or Retina.
Biometrics for personal devices original was
introduced by finger print scanners for laptops
and later voice and facial recognition software
for computers, laptops, smart phones and
tablets.
 Siri for iphone have a new voice recognition
software usable instead of a password.
 Finger print scanning technology is still the most
commonly used today as it is by far the easiest
and most reliable to use.
 However usernames and personal passwords are
by far and a way the most popular form of
security.

PROS
Protects against
fraud.
 Fast access no chance
of forgetting the
password.
 Do not have to
remember large
amount of passwords.

CONS
Costly to implement.
 Discriminatory.
 Intrusive people have
fears about the uses
of their information.
 Some biometrics such
as voice recognition
are possible to fake
with a recording.

In the future for personal devices I see some
biometrics more realistically being used than
others.
 As cameras for phones become better facial
recognition software may be used.
 I also see palm print scanners possible for
Tablets.
 I don't for see voice recognition to last very long
as it is not very secure and is open to theft.
 Other biometrics may be used but the software
and hardware are simply far to expensive in
comparison to the ones in use today.

 To
ensure against a fail in biometric or to
just ensure the safety of a device it is almost
necessary to use two biometrics.
 For example palm print and facial
recognition.
 Using dual biometrics slows down the speed
of use of biometrics but also increases the
cost vastly.
 Certain
biometrics are just not viable due to
user acceptability.
 Fingerprints are not social acceptable to use
this may be due to the fact that they are
associated with crime and government
control.
 Iris and retina scanners are extremely
intrusive and would have a lot of people
refusing to use them.
