Problems solved by technology

According to the introduction of the Monetary Authority of Singapore, at present, the anti-counterfeiting of Singapore currency is mainly through gravure printing in terms of visual and tactile differences, as well as anti-counterfeiting features such as watermarks, security lines, transparent windows, and embossed windows. Under the light, the denomination number, serial number and fluorescent fiber in the banknotes that reflect the light can distinguish the authenticity of the banknotes. There is no method to use the image characteristics of the banknotes to identify the authenticity of the banknotes.

Embodiment 1

[0053] This embodiment provides a method for authenticating banknotes, which can use the image characteristics of banknotes to identify the authenticity of banknotes. The counterfeit identification method is realized by a counterfeit identification device for banknotes. The counterfeit identification device is composed of software and / or hardware, and is generally integrated in money detectors, self-service teller machines and other equipment that need to identify the authenticity of banknotes.

[0054] figure 1 It is a flow chart of the banknote authenticating method provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the method for authenticating includes the following steps:

[0055] S11, intercepting a characteristic area on the infrared transmission image of the banknote.

[0056] The banknote is transmitted by an infrared spectrometer, and the characteristic area is intercepted at a preset position on the infrared transmission map of the bank...

Embodiment 2

[0064] This embodiment provides a method for authenticating banknotes. Based on the above-mentioned embodiments, taking the Singapore currency with a denomination of 50 yuan as an example, it is judged whether the characteristic image on the banknote is a preset regular octagon.

[0065] figure 2 It is a flow chart of the banknote authenticating method provided by Embodiment 2 of the present invention. Such as figure 2 As shown, the method for authenticating includes the following steps:

[0066] S21, intercepting a characteristic area on the infrared transmission image of the banknote.

[0067] image 3 It is the infrared transmission diagram of the 50 Singapore dollars provided by the second embodiment of the present invention. First carry out face-to-face recognition on banknotes, such as image 3 As shown, on the infrared transmission map of the front of the banknote, the characteristic area 20 is the part to be intercepted. On the infrared transmission map, the pos...

Embodiment 3

[0097] This embodiment provides a counterfeit identification device for banknotes, which is used to implement the counterfeit identification method described in the above embodiments, solve the same technical problem, and achieve the same technical effect.

[0098] Figure 4 It is a structural schematic diagram of the banknote authenticating device provided by Embodiment 3 of the present invention. Such as Figure 4 As shown, the counterfeiting device includes: a feature interception module 31 , a boundary detection module 32 and a shape judgment module 33 .

[0099] The feature capture module 31 is configured to capture a feature area on the infrared transmission image of the banknote.

[0100] The boundary detection module 32 is configured to detect the boundary of the feature image in the feature area.

[0101] The shape judging module 33 is configured to determine that the banknote is genuine if it is judged according to the boundary that the characteristic image is a p...

Abstract

The invention discloses a banknote authenticating method and device. The counterfeiting method includes: intercepting a characteristic region on the infrared transmission map of the banknote; detecting the boundary of the characteristic image in the characteristic region; and determining that the characteristic image is a preset shape according to the boundary, then determining the is true. The present invention determines that the banknote is genuine by identifying the feature image on the infrared transmission image of the banknote and judging that the feature image is a preset shape. Using the difference in material or magnetism of the characteristic area, the gray scale of the infrared transmission image obtained is different to identify the characteristic image, and judge whether the characteristic image conforms to the characteristics of the preset shape through the shape of the characteristic image. The present invention utilizes the characteristics of the banknote itself , the features extracted by means of infrared transmission are remarkable, which is convenient for further identification, and the counterfeiting method is simple and effective.

Description

technical field [0001] The invention relates to the technical field of banknote identification, in particular to a banknote identification method and device. Background technique [0002] The Singapore dollar (referred to as: SGD or SGD, formerly known as SGD, English: Singapore Dollar) is the legal currency of Singapore, marked with S$. In 1999, Singapore issued the banknotes currently in circulation, a new version of banknotes with the portrait of the country's first president Yusof as the main pattern on the face. The banknotes currently in circulation in Singapore have denominations of 10,000 yuan, 1,000 yuan, 100 yuan, 50 yuan, 10 yuan, 5 yuan, and 2 yuan. According to the introduction of the Monetary Authority of Singapore, at present, the anti-counterfeiting of Singapore currency is mainly through gravure printing in terms of visual and tactile differences, as well as anti-counterfeiting features such as watermarks, security lines, transparent windows, and embossed w...
