ATM THREAT DETECTION SYSTEM

Objective:

The main objective of this project is to prevent forced ATM theft, using GSM technology.Working :

When any ATM user enter into an ATM to withdraw money for his need, and suddenly thief’s enters into the ATM with a knife or a pistol, and force you to withdraw the entire amount in your account (considering the ATM has no security guard and is in a remote place). In these situations this project gives security as well as safety to user.

In this every ATM user is provided with 2 passwords one is original and other one is dummy which is helpful in this situation as, when you are forcibly attempting to withdraw money, and you are entering a dummy password instead of your actual password. After that ATM shows that you have less than minimum balance in your account (even if you have plenty) and you are unable to withdraw simultaneously a message will be sent through GSM modem to near by all police stations and concerned bank regarding thieves in ATM centre. And thief’s tries to get out of the ATM, they will come to know that the ATM is surrounded by armed police and there is no way to escape.

4. Global System of Mobile communication Module:

GSM is a second generation cellular standard developed to cater voice services data delivery using digital modulation. You need to insert SIM from your GSM provider to activate and Start using GSM modem.

An RFID reader typically contains a module (transmitter and receiver), a control unit and a coupling element (antenna). The reader has three main functions: energizing, demodulating and decoding. Anti-Collision algorithms permit the simultaneous reading of large numbers of tagged objects, while ensuring that each tag is read only once. The card reader is interfaced with micro control.

Proximity card is a generic name for contact less integrated circuit devices used for security access or payment systems. It includes both the older 125 KHz devices and the newer 13.56 MHz contact less RFID cards. It contains an IC, capacitor, and coil is connected in parallel. The card reader presents a field that excites the coil and charges the capacitor, which in turn energizes and powers the IC. The IC then transmits the

Advantages:

1. Provides very good security to ATM users.

2. Use of RFID allows only authorized users to use ATM facility.

3. Alerts near by police stations during theft through GSM modem.

FUTURE ENANCEMENT:

1. This project can be implemented for office security also.2. Also to colleges, hospitals and also in parking system.
