• Increasing automated and growth of modern
  technological systems, such as cellular phones
  and internet, have led users to the existing use
  of technical methods alternatively of human
  people for obtaining authentication. Individual
  personality has progressed to the capability of
  private PIN's and passwords. Passwords are
  consistently utilized in things such as cellular
  phones, ATM's, personal computers or access to
  the internet. But, there is a problem with using
  the system of passwords for security reasons.

• For creating the password non-accessible to other
  people, it has to be exclusive, not present in
  the vocabulary and has to consist of designs like
  , , or _at_. Moreover, for security resolves, a
  password has to be not written, never given
  access to other people, and has to be changed a
  minimum of after every three months. People these
  days, use as massive quantities of passwords and
  it becomes problematic for keeping in mind these.
  While the passwords are regarded machine helpful,
  they are for from becoming user helpful.

There are several ways by which biometric
verifications are done. Some of them are
mentioned below.

• Authentication of the palm vein

• Finger Identifications

• The side of fingerprints are established in the
  uterus just at the finalization of four months of
  development of the fetus. The fingerprints thus
  formed are like pictures present on a balloon's
  surface. The fingers of a person get large with
  increasing age, but, the relation between the
  fingerprint ridges is constant throughout. This
  is why fingerprint identifications are considered
  trustworthy.

• The authentication of the palm veins is a system
  in which infrared beams are used for penetrating
  the hands of the users while waving them over the
  authentication systems. The palm veins get
  returned back in the form of black lines. The
  complex nature of the vein pattern makes this
  system accurate. As the veins are present inside
  the body of a person, this system is difficult to
  counterfeit.

• The retina scans

• Iris scans

• The method of scanning the retina involves
  analyzing capillary blood vessels which are
  present in the eye. This pattern does not change
  throughout the lifespan. A light of low intensity
  is used for taking the images of the patterns of
  blood vessels. It is a very reliable method of
  identification used by biometrics.

• Scanning the iris is a method in which the
  freckles, rings and the furrows present in the
  ring which fences the pupils of the eyes are
  scanned. The method involves the use of close to
  200 points for comparing and is very reliable.
