Comparative Analysis of Finger Vein, Iris and Human Body Odor as Biometric Approach in Cyber Security System

Information security has become an indivisible part of the emerging Information and Communication Technology [ICT] applications. In particular, authentication plays an extremely important role in dealing with security. A review on the biometric authentication techniques and few future possibilities in the fields of Information security is presented in this work. The basis of biometrics is that an individual is identifiable by a few characteristic and physiological parameters. To affirm or determine the identity of any particular individual, most of the systems require personal recognition schemes which are distinctive and equally reliable. This assures the authentication of the people requesting their services. This ensures that only legitimate users can access the services and not anyone else. The use of biometrics also allows to establish or approve an individual's identity. The position of biometrics in the present field of security can be deduced from this work. This paper outlines a comparison between three different techniques and their advantages and disadvantages over each other. Comparing these three techniques, we were able to deduce that the finger vein recognition system showed a good balance in every aspect.
