Abstract:
    The invention relates to a method and device for discriminating the genuine-fake of paper receipt based on infrared discrimination watermark. The receipt to be detected is through the infrared field via transmission means, the optical receiver covered with watermark pattern detects the transmitted light in the watermark area of receipt in motion procedure, complete the photoelectric signal conversion; output to the sampling module and the digital signal characterized the watermark is obtained by analogue/digital conversion; the analog of watermark which is obtained from the mathematical model complex characterization is as the criterion to discriminate genuine or fake to judge the genuine-fake of the watermark, the central processing unit executes the recognition program of discriminate genuine or fake of watermark, and output the discrimination result. The central processing unit is connected with the controller and memory, the controller is connected with the transmitting means. The invention discriminates genuine or fake by computer module discrimination technique, and the false proof means can be processed by more advanced and accurate device, and make the speed of discrimination technique more fast and the result more accurate.
