Abstract: The current paper money identification techniques arc based on safcline, watermark, magnetic inks, fluorescence ink, etc. Alone with the development of fake technology, the anti counterfeit technology needs new ways. This paper presented a brand-new anti-counterfeit method, which is based on the intaglio character of the paper currency, using a common flatbed scanner to achieve the pseudo binocular stereo image of the paper currency, and recognizing the relief texture to identify the real or fake currency. Furthermore, we also brought out a pseudo binocular stereo scanner prototype, which is a better currency detector with high efficiency. With the benefits of this scanner, our method can be applied automatically and is much faster.
