Enhancing ATM Security using Fingerprint and GSM Technology

There is need for improve security in ATM transactions. Due to tremendous increase in the number criminals and their activities, the ATM has become insecure. ATM systems today use no more than an access card and PIN for identity verification. The Personal Verification Number(PIN) not only give good security. The fingerprint is unique and cannot duplicate by others. This paper combine the pin verification and fingerprint recognition technology for identification. With fingerprint recognition technology and pin verification we embedded the GSM modem connected to the microcontroller generates the 4 digit one time password and it send to the main user mobile number when the user (main user or nominee user) enroll the fingerprint. The fingerprint of the nominee and the card holder are collected and stored in the database. Every fingerprint which enrolls is check by the db. The 4digit one time password should be entered by pressing the keys on the touch screen. After enter all the correct information customer can begin the further transaction. We also proposed nominees fingerprint identification process while actual card holder unable to do the transactions. The biometric features cannot be replicated, this proposal will go a long way to solve the problem of account safety.
