REAL TIME SMS – BASE HASHING SCHEME FOR SECURING FINANCIAL TRANSACTIONS ON ATM

Abstract : Our project proposes a secured ATM (Automated Teller Machine) system using a card scanning system along with LINK system for improved security. Usual ATM systems do not contain the LINK feature for money withdrawal. If an attacker manages to get hold of ATM card and the pin number, he may easily use it to withdraw money fraudulent. So our proposed system supports the ATM card scanning system along with an LINK system. This user may scan his card and login to the system. But after user is through with this authentication he may view details but is asked to enter LINK as soon as he clicks money withdrawal option. At this stage the system generates and sends an LINK to the registered mobile number to that particular user. The password is generated ad sent to the user mobile phone. He now needs to enter the LINK in the system in order to withdraw money. Thus our system provides a totally secure way to perform ATM transactions with two level security structure

 EXISTING SYSTEM :

 The existing ATM Simulation System was built for the original concept of regional private banks. Small banks in villages and towns will service the needs of the local community and will only require ledgers to record account details. This system is prone to human error and causes undue frustration to users. This system was augmented with the introduction of excel sheets and emails. Banks could now record all information in an excel sheet and then set an update schedule when they will mail all records to a central hub where these records will again be processed and consolidated to form a unified record of all account transactions. These systems did not enable easy access to money and were greatly prone to grievous errors.

 DISADVANTAGE :

 This paper provides security system for ATM machines. Now a day there is no particular security system for ATM machines. The only security system provided at the ATM centres is ATM card detector near the doors. If the inserted card is authorized, then the door will open automatically

 PROPOSED SYSTEM :

 The proposed system aims to solve all this by constant updating of bank records. The Java based construction of the system will enable transactions at any bank or ATM to be registered within a matter of seconds. Security of these details is also a top priority in this system. This central hub will be accessed by an ATM for secure customer transactions. In our project we are going to place an extra button in ATM machines. When that button got pressed the control window will be telecasted to accountant cellular phone. Then the accountant can enter the pin and amount manually in his mobiles telecasted pop-up window. By this control system accountant can keep his pin number with him and he can vend the amount by his own control by the desired person

 ADVANTAGE :

 This paper gives the description of the new approach towards the security of ATM (Automatic Teller Machine) systems. The objective of the paper is to know the Enhanced smart ATM security system which is developed using the Embedded system and advanced technologies. In our proposed system RFID card is used as ATM card, IR sensor in order to sense the presence of the card holders and to turn on Fan and Light, if ATM is tampered then SMS is sent to two main stations via GSM. GPS is used to track the location in case the cash box is robbed. Finger print is used to identify and verify authorized bank personnel. Hence the proposed system is the highly secured system for ATMs.
