Abstract
The main objective of this system is to develop an
embedded system, which is used for ATM
security
applications. In these systems, Bankers will collect the
customer finger prints and mobile number while opening
the accounts then customer only access ATM machine. The
working of these ATM machine is when customer place
finger on the finger print module when it access
automatically generates every time different 4-digit code as
a message to the mobile of the authorized customer through
GSM modem connected to the microcontroller. The code
received by the customer should be entered by pressing the
keys on the touch screen. After entering it checks whether it
is a valid one or not and allows the customer further access.
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. Using
the ATM (Automatic Teller Machine) which provide
customers with the convenient banknote trading is very
common. 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. How to carry on the valid identity to
the customer becomes the focus in current financial circle.
Traditional ATM systems authenticate generally by using
the credit card and the password, the method has some
defects. Using credit card and password cannot verify the
client's identity exactly.
THE CHARACTERISTICS OF THE
SYSTEM DESIGN
The embedded ATM client authentication system
is based on fingerprint recognition which is designed after
analyzed existed ATM system. The S3C2440 chip is used
as the core of these embedded system which is associated
with the technologies of fingerprint recognition and
current high speed network communication.
The primary functions are shown as follows:
• Fingerprint recognition: The masters' fingerprint
information was used as the standards of
identification. It must certify the feature of the
human fingerprint before using ATM system.
• Remote authentication: System can compare
current client's fingerprint information with
remote fingerprint data server.
• Message alarming: different 4-digit code as a
message to the mobile of the authorized customer
without any noise, in order to access the
Terminal.
Software design
The design was component of three parts
included the design of main program flow chart, the
initializing ones, and the algorithm of fingerprint
recognition flow chart.
This system of software is implemented by the
steps as follows: first of all, the Linux kernel and the File
system are loaded into the main chip. The next, the system
is initialized to implement specific task, such as checking
ATM system, GSM communication and so on, and then
each module reset for ready to run commands. Before
using ATM terminal, the mobile number and fingerprint
of the customer is required.
RESULTS & CONCLUSIONS
The Implementation of ATM security by using
fingerprint recognition and GSM MODEM took
advantages of the stability and reliability of fingerprint
characteristics. Additional, 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.
