A PROPORTIONAL LEARNING ON SMART CARD AUTHENTICATION

A smart card is a pocket sized card embedded with integrated circuits. Smart Cards are used in a wide range of industries worldwide to support access, identity, payment and other applications. Even though the smart cards are widely used, the hidden information can be easily read by the hackers. In order to secure the authentication, first password authentication was done. As it is very easy for the hackers to guess the password later two-factor password authentication was introduced. In that password and the users information was hidden. But this type of authentication was also not reliable. Later biometric authentication was introduced. In this type of authentication the finger print scan, retina recognition and voices were used for the means of identifying people. This type of authentication is also not reliable as there will be changes in the human body when become aged. Now another type of authentication is introduced in some of the places, that is with the help of the chip inserted in the body. It is human implantable chip known as Verichip. This article is a comparative study on the various types of smart card authentication.
