CURRENCY AUTHENTICATION USING MATLAB

Today the ubiquitous distribution of high technology scanning and printing equipment enables the
"home" user to make counterfeits of high value documents like checks, tickets, licenses,
identification cards and other secure documents. High value documents have been and will continue
to be forged as long as the value realized from the counterfeiting is higher than the cost of
duplicating the original. There are no perfect counterfeits, and there are no p erfect d esigns fully
immune to counterfeiting. In the past, the hands of craftsman and a perfect eye were required to
make a high quality counterfeit. Today, highly sophisticated, state-of-the-art reprographic systems
do not require skilled professionals to operate them. They are widely available to the general public.
These devices are generally simple to use and create an "opportunity" for the "home counterfeiter".
It is becoming i ncreasingly difficult to spot alterations or counterfeits using only human sensory
evaluation. There is an ever-increasing demand for new technologies and methods of counterfeit
detection and forensic analysis to safeguard the integrity of high value documents. This is where
process of authentication comes in. The aim of the project is to produce a reliable system that offers
an easy and effective authentication technique of a currency. The objectives of Currency
Authentication are to design a system that will be able to evaluate the integrity of currency contents
relative to the original and of being able to detect, in an automatic way, malevolent currency
modifications. For these purposes system software must be developed based on current available
techniques and mechanisms.
