The invention discloses an anti-counterfeiting detection device and method for banknote magnetic full-buried security thread, comprising: a light-transmitting detection device arranged above the banknote conveying channel, and acquiring the transmission light of the banknote passing through the conveying channel irradiated by a light source relatively arranged below the conveying channel image; the image processing device extracts the shape feature of the magnetic fully buried security thread on the banknote transmission image; the magnetic detection device detects the magnetic signal of the magnetic fully buried security thread on the banknote passing through the transmission channel; the signal processing device processes the magnetic signal and obtains The two-dimensional code of the magnetic fully buried safety thread; the authenticity discrimination device judges whether the shape feature of the magnetic fully buried safety thread conforms to the predetermined shape feature, judges whether the two-dimensional code is the specified two-dimensional code, and when all judges are yes, judges The banknote is genuine, otherwise it is determined that the banknote is counterfeit. The anti-counterfeiting detection and double detection of the safety thread can be realized simply and conveniently, and the accuracy and reliability of the anti-counterfeiting detection are high.
Description
technical field [0001] The invention belongs to the technical field of anti-counterfeit detection, and in particular relates to an anti-counterfeit detection device and method for banknote magnetic fully-embedded safety threads. Background technique [0002] Banknotes are widely used as circulation media in the economic market, and with the development of the market economy, various counterfeit banknotes are also emerging in an endless stream, and counterfeit banknotes will also appear during the use of banknotes. In order to ensure the authenticity of banknotes, all kinds of counterfeit , The demand for testing equipment is getting bigger and bigger. [0003] All kinds of counterfeiting and detection equipment check the authenticity of banknotes through various anti-counterfeiting features on banknotes. The magnetic fully buried security thread on banknotes is one of the anti-counterfeiting features of banknotes, and it is also one of the anti-counterfeiting features that o...
