Identification and verification of a person today is a common and important thing while accessing bank accounts via Automated teller machine. The current using methods like ID card checking or signature verification does not provide that much perfection and reliability. Fingerprint based identification is one of the most mature and proven technique. The main objective of this system is to make ATM transactions as secure as Possible. With the standard using Automated teller machine (ATM) the criminal cases are increasing so because of that bank customers faced to the financial losses. Since, it is much needed to improve the standard identification ways with ATM. In this paper we proposed that fingerprint verification of ATM (Automatic Teller Machine) security system. The fingerprint concept is chosen, because it provides availability, reliability uniqueness with high accuracy. The system verifies fingerprint images with saved fingerprint and gives accurate result that if it valid or invalid to the user who using the ATM machine. In this way we can enhance the security of ATM system to control the increasing crime circle of ATM. Keywords fingerprint, Biometric, ATM system, Reliability, PIN. I. INTRODUCTION An automatic teller machine is a computer based machine connected to a network that offers a basic function to users, access to bank accounts (balance, back transfers) and retrieval of money. While accessing the ATM card there are many chances for the card to stolen, lost, replicated, left behind or the password can be easily shared because some people may write it on paper for easy remembering or the password may be forgotten, hacked or some may observe your password and copy it. As we all know, the physical characteristic of each individual is different and unique. So, we can use these physical characteristics to identify and verify the user. There are many physical characteristics which can be used such as face, iris, retina, voice, eyes, fingerprint. Fingerprint technology is the most widely accepted and mature biometric method and is the easiest to deploy and for a higher level of security at your fingertips[2]. The fingerprint identification scanner is easy to install and very time efficient to acquire user s fingerprint. ATMs offer the convenience of multiple locations. You can withdraw cash at any bank that is part of the system to which your ATM card is linked. Although fingerprint images are initially captured, the images are not stored anywhere in the system. Instead, the fingerprints are converted to templates from which the original fingerprints cannot be recreated; hence no misuse of system is possible All rights Reserved 489

2 II. EXISTING BANKING SYSTEM Figure 1. Working of Existing Banking System. Now-a-days people don t have that much time where they can go to the bank and spend there precious time by standing in the queue to carryout banking transaction like withdrawing, depositing, transferring and balance enquiry. So, the banking technology has already introduced the feature i.e. ATM (Automatic Teller Machine) using which the user can be able to perform several banking transaction such as cash withdrawal, cash depositing, cash transfer and balance enquiry. So, the ATM system is very user-friendly which connect the user with its bank account. ATM provides customers a fast and convenient way to access there bank account and financial transaction without any limitation of time and place. In the existing ATM System the user is provided with the 4 digit Personal Identification Number i.e. PIN by bank for accessing the banking transaction. Password or Personal identification number(pin) is one the important aspect in ATM security system which is commonly used to secure and protect financial information of customers from unauthorized access[10]. The ATM card is protected by the PIN for keeping the user s money save. When user enters the PIN in the ATM System, the system checks that the entered PIN of that ATM card matches with the registered PIN stored in the database of the bank s Server. If the entered PIN is valid for that card than user will get the access to perform the banking transactions. And if not than the transaction is aborted with an error message which is displayed on the screen. The above figure shows the working of traditional ATM system[]. Advantage of using ATM is that we can use it to withdraw cash at any time, day or night. The bank don t need to be open. III. PROPOSED SYSTEM With the existing system the number of criminal cases is increasing frequently in recent years. A lot of cases associated with ATM crime have been registered where the hackers tamper with the ATM system and steal customer s card details by unauthorized ways. If the user s ATM card All rights Reserved 490

3 been stolen and the PIN is hacked then the user s account is exposed to attack. So the existing system is not fully secured to provide security to the authorized user. To overcome these security related disadvantage of the existing system we have proposed a system where authorized user is verified with the fingerprint technology. The proposed system uses the fingerprint technology because the fingerprint provides uniqueness to identify authorized user and it is most reliable and affordable than any other technology. The proposed system operated using only ATM card and fingerprint scanner. This system provides high level of security to cardholders since there is low possibility of misuse of card and theft. With this proposed system the customer has no need to worry about the money even if the card is stolen as the customer knows that no one can replicate his/her fingerprint and withdraw the money[10]. When the customer gets the PIN no. for the ATM card from the bank then at the same time the customer has to give their fingerprints to the bank which is stored and is assigned as the PIN for accessing the bank transaction.

5 IV. METHODOLOGY The security feature for enhancing the Indian banking ATM was designed using the client/server architecture. There will be a connection between the customer s identification information, customer s accounts and records in the bank[das]. The ATM PIN nos. are 4-digit numbers in the range resulting in 10,000 possible numbers, so that an attacker would need to guess an average of 5000 times to get the correct PIN. So by keeping these above thing in mind we can provide more security to the PIN. When the bank give 4 digit PIN no. to the ATM card holder than at that time the user has to assign 4 fingerprints as per his/her choice for the 4 digit PIN no. respectively. So, here the 4 digit PIN No. is converted into four fingerprints respectively of one authorised user. For example, if the PIN assigned to the user is 1204 the bank officers will ask the user to select the fingers of their choice and store that fingerprint in the database along with the PIN no. So, if the user has pin no. like 1204 then the user have to select one individual finger for one digit and so 4 fingers will be assigned for the 4 digits of PIN no which will be used by the user to perform the banking transaction. So when the user want to access the banking transaction with ATM then instead of entering the 4 digit pin no., he/she have to scan his/her fingers according to the PIN no. sequence which they have provided to the bank at the time of registration. Figure 4. Example if PIN no. is 1204 There are chances for hacking the fingerprint even if it is incorporated in the existing system, but the proposed system uses fingerprints in a particular sequence which only the user knows and the chances of the fingerprint theft is negligible because while entering the pin the user have to scan the finger one after the other on the same scanner, so it makes the process of hacking or copying the fingerprint image more complicated as it will make it difficult for the hacker to understand the sequence and identify each finger individually. V. ADVANTAGE OF PROPOSED SYSTEM 1. Fingerprint scanning technology in ATM provides accuracy because identical matches of fingerprints are nearly impossible. 2. The image template of scan fingerprint requires less memory to store. 3. Implementation of this system provides more security to ATM transaction and improves All rights Reserved 493

This technique will provide high level of security for the existing ATM system using fingerprint based pin recognition strategy. If this system will be used by Banks then the cases of fraud, ATM crime may reduce to a certain extent and will provide more reliability, to the authorized user REFERENCES [1] Mr. Mahesh A.
