Introduction

Now-a-days, in the self-service banking system has got extensive popularization with the characteristic offering high-quality 24 hours service for customer.

However, the financial crime case rises repeatedly in recent years, a lot of criminals tamper with the ATM terminal and steal user's credit card and password by illegal means.

Once user's bank card is lost and the password is stolen, the criminal will draw all cash in the shortest time, which will bring enormous financial losses to customer.

Traditional ATM systems authenticate generally by using the credit card and the password, the method has some defects

The original password authentication method combined with the biometric identification technology verify the clients identity better and achieve the purpose that use of ATM machines improve the safety effectively.

Gives 2 way security authentication process with the help of fingerprint system sends dynamically generated PIN or code to customer mobile number.

The design of fingerprint recognition algorithm

The fingerprint recognition algorithm is composed of two main technologies: image processing technology matching algorithm technology

GSM

Global System for Mobile Communications ( GSM: originally from Group Special Mobile) is the most popular standard for mobile phones in the world.

GSM uses a variation of Time Division Multiple Access(TDMA)

GSM is the most widely used in digital wireless telephone technologies

It operates at either the 900 MHz or 1,800 MHz frequency band.  

CONCLUSION

The Implementation of ATM security by using fingerprint recognition and GSM MODEM took advantages of the stability and reliability of fingerprint characteristics

The system also contains the original verifying methods which was inputting owner's password which is send by the controller.

The security features were enhanced largely for the stability and reliability of owner recognition.

The whole system was build on the technology of embedded system which makes the system more safe, reliable and easy to use.
