Abstract Counterfeiting, in particular, the forgery of banknotes is a serious crime problem and has become a great challenge to the global economies.The forensic science experts have been utilizing chemical technique such as infrared spectroscopy to analyze genuine and copyright banknotes.Nevertheless, chemometrics techniques are required to further discriminate the banknotes.

In this paper, an advanced fuzzy graph chemometrics method is used to discriminate genuine and copyright fifty Ringgit Malaysian (RM50) banknotes.The development of the technique, namely chemometrics read more fuzzy autocatalytic click here set (c-FACS) is presented in this paper, together with the results and its comparison to principal component analysis (PCA) method.The results from the c-FACS analysis showed distinct patterns and features of the copyright banknotes in the c-FACS plot.

Furthermore, the new method is faster than PCA in authentication analysis of copyright banknotes.Hence, the c-FACS provides better performance in terms of computing time as compared to PCA, and has the potential in assisting the investigation involving copyright banknotes.
