ADVANCED SECURITY ATM TRANSACTION

Electronics and Telecommunication

Using an Automatic Teller Machine, customers can access their bank accounts. ATMs were originally developed as just cash dispensers; they have evolved to include many other bank-related functions such as Purchasing, Postage stamps, Lottery tickets, Train tickets. The problem is that, if our debit card is lost then we cannot transact the account. Also if our friend wants money from us immediately then we cannot give the money by ATM. In this modern world ATM is being used by everyone. The security that is being currently used for ATM indeed has a few backdoors and it can be improved further. For the same In this system GSM module as well as biometric verification were introduced. But even the biometric system does not seem to be completely reliable and hence a contingency plan is needed in order to prevent catastrophes. Objective of this paper is to provide high level security to ATM by enhancing the already proposed biometric system and making it still secured by PII[Personal Identification Image] process. So a detailed study on various existing biometric systems is studied and also its limitations are listed. This paper proposes a novel method to meet out the challenges and strengthen the security mechanism. In the proposed security algorithm two phases are defined. These two phases provide two high level security and there by increases the security of ATM machine.
