Fake identification system of bank bills based on spectral image analysis

Abstract

The invention discloses a fake identification system of bank bills based on spectral image analysis, which uses a device and adopts a method of multispectral analysis to excite the anti-fake characteristics on the standard samples of bank bills so that the anti-fake characteristics, such as paper characteristics of paper, fiber, watermark, printing ink, format, print, writing information and the like, are shown, and finally collects, inputs and establishes a standard image database. The database is edited by a computer language and then application software is generated so as to form the fake identification system of bank bills together with the device. A plurality of main anti-fake characteristics of the identified bank bills, such as the paper, the print, the printing ink, the writing information and the like, can be identified under all different light sources, such as illuminating light sources, main light sources, side light sources, backlight sources, long-wave ultraviolet rays, short-wave ultraviolet rays, anti-face laser, infrared light sources and the like. The system is applicable to the technical field such as the anti-fake identification of the bills circulating on the market and is capable of detecting all anti-fake characteristic points of the bills. Synchronously, a network supervision system is established.

Description

[0001] 1. Technical field [0002] The invention is a system for identifying and discriminating counterfeit bank notes based on spectral image analysis. It uses a device and adopts the method of multi-spectral analysis to accurately identify the paper quality, fiber, watermark, format and writing information of bank notes, and identify its authenticity. At the same time, it provides advanced technical means for bill information management. Through network connection, real-time dynamic management of bill image information in the system can be realized, and an information platform can be established. 2. Background technology [0003] At present, the existing bill recognition software and hardware at home and abroad are all realized based on some limited technical means, and they basically use magnetic signals, ultraviolet, infrared, IR scanning and other relatively characteristic detection methods to complete the recognition. The anti-counterfeiting device is mainly composed of...

AI Technical Summary

Problems solved by technology

The anti-counterfeiting device is mainly composed of a single battery, a resistor, an ultraviolet lamp, and a magnifying glass. The surface of the bill is directly irradiated by ultraviolet light. Under the excitation of ultraviolet light, the ultraviolet anti-counterfeiting features of the bill are directly observed with the naked eye. The disadvantage is that the authenticity of bills is greatly affected by the environment, the anti-counterfeiting features are single, the accuracy is low, and the processing speed is slow. It needs to be observed directly with the naked eye, and the display effect is poor.

[0004] With the continuous improvement of counterfeiting technology in the world today, corresponding countermeasures have been taken for this relatively simple anti-counterfeiting technology, which leads to the existing identification or identification technology prone to errors or even wrong identification, which has great disadvantages
