					AN OVERVIEW OF
BIOMETRIC ATMs
                WHY ?
 CONVENTIONAL ATMs -> BIOMETRIC ATMs

 Environmental   Concerns



 Security   Concerns
    ENVIRONMENTAL CONCERNS
 In conventional ATMs – PIN is needed
 PIN comes in an envelope which contains
  2 sheets of paper and between this
  sheets secret code is marked
 RBI report says – 25000 new accounts
  are opened daily
 On yearly basis, a lot of paper is required
  – leads to cutting of trees
     SECURITY CONCERNS
 Anybody holding the card with PIN number
  known can operate
 No need to be the original owner of the
  card
 In Bio metric only the original card holder
  can operate
         BIO METRIC ATMs
 Biometrics refers to the automatic
  identification of a person based on his
  physiological/behavioral characteristics.
 Various types of biometric systems are
  being used for real time identification;most
  popular are based on face recognition and
  finger print matching.
           WHY USE IT?
 Traditional methods involving passwords
  and PIN numbers
 Biometrics highest level of security

VARIOUS BIOMETRIC SYSTEMS
1.   HAND
          The three dimensional shape of a
     person’s hand has several advantages
     as an identification device. Scanning a
     hand and producing a result takes
     1.2seconds.It requires little space for
     data storage about 9 bytes which can fit
     easily magnetic strip credit cards.
2.   FINGER PRINT
           Most of the work in biometrics
     identification has gone into the finger
     print for general security and access
     control application fingerprints are
     gaining popularity.

5.   SPEECH
          MULTIBIOMETRICS
1.   INTEGRATING FACES AND FINGER PRINTS
     FOR PERSONAL IDENTIFICATION
           An automatic personal identification
     system based on fingerprints or faces is often
     not able to meet the system performance
     requirements.
          MULTIBIOMETRICS
2.   A MULTIMODEL BIOMETRIC SYSTEM
     USING FINGERPRINT, FACE AND SPEECH
            This system takes the advantage of the
     capabilities of each individual biometric. It can
     be used to overcome some of the limitations of
     a single biometrics.
            CONCLUSION
    A range of biometric systems are in
developments or on the market because no one
system meets all needs. The trade off in
developing these systems involve component
cost, reliability, discomfort in using a device, the
amount of data needed and other factors. But
the application of advanced digital
techniques has made the job possible.
Further experiments are going all over the
world.
