Abstract

The embodiments of the invention disclose a banknote identification method and apparatus. The method comprises the following steps: obtaining fluorescent areas of banknotes to be verified, and calculating a mean value of the fluorescent areas; according to preset rules, dividing other areas apart from the fluorescent areas in a front area comprising the fluorescent areas, and / or dividing a back area not including the fluorescent areas; and comparing the mean value of the fluorescent areas with a mean value of a subgraph after division on each surface, and according to a comparison result, determining authenticity of the banknotes to be verified. According to the invention, the authenticity of the banknotes is detected by use of the feature that counterfeit banknotes have other areas as bright as the florescent areas, so that the identification rate of the counterfeit banknotes is improved and the banknote identification time is reduced.
