RU192018U1 - Banknote Detector with Advanced Banknote Authentication - Google Patents

Abstract

Improving the quality of counterfeit bills and a huge fleet of outdated banknote reception and control devices in the retail payment network are a direct cause of alarming information about the increase in the volume of counterfeit money and even the fact that ATMs issued counterfeit bills, which indicates the insufficient effectiveness of bill acceptors used in ATMs terminals and vending machines for detecting counterfeit currency. This is due to the fact that the built-in sensor set of bill acceptors of the early years of release was focused mainly on highly reliable automatic detection of banknote denomination and rejection of coarse fakes, and for this reason, they are not effective enough to detect modern, very high-quality fakes. The inventive detector exceeds the capabilities of the previous generation, because it uses more sophisticated control methods to detect fakes. Unlike bill acceptors of previous years, the claimed banknote detector, in addition to the generally accepted set of sensors, is additionally equipped with a built-in video camera-microscope that automatically detects deterioration of the print quality of protective graphic elements on the surface of the banknote under high magnification. The final conclusion about the authenticity of the banknote being checked is automatically generated by the detector after evaluating the print quality of the micro-font printed on the banknote (especially in negative printing mode) and checking the absence of a pixel structure in the colored figures, symbols and finest lines of the banknote pattern applied to the banknote (which is typical for fake banknotes made using color printers), as well as individual fragments of a banknote drawing that are difficult to reproduce without the use of typographic technology. The printed photographs illustrate genuine banknotes (photo 1 on the right in the upper and lower rows, and photo 2 on the right in the upper and lower rows) compared to fake banknotes (photo 1 on the left in the upper and lower rows, and photo 2 on the left and middle shots in the lower and upper rows). At the same time, the stratification of solid colored lines into pixels is clearly visible when printing on a color printer. The attached photo No. 2 clearly shows the "colored grain" on the gray elements of the image of the counterfeit note (bottom row, left and middle pictures), poor quality of the lines of rhombuses in negative printing. In the top row of the same photo: loss of clarity of numbers during negative printing (left and middle shots). The desktop version of the device is intended for mass use at all cash-in points - at the cash registers of shops, service enterprises and bank branches, and made in the form of a validator (bill acceptor) ) - for the installation and mass replacement of existing bill acceptors of the old type in all types of banking, vending and payment terminals.

Description

The technical field to which the utility model relates.

The invention relates to electronic equipment, in particular to banknote authentication devices. The device contains an electronic controller with a set of sensors and a banknote - a lingering mechanism with which the bill extends past the line of optical sensors processed by the controller.

The technical result consists in increasing the reliability of recognition of the authenticity of banknotes.

State of the art

A device is known in the art comprising a housing, a receiving tray, a keyboard, a display, a bill-pulling mechanism including rollers, an electric motor with a tachometer sensor, a control device, a sensor device and a storage device. This device further comprises a piezoelectric sound signal generator associated with a control device, which is configured to receive a signal from a sensor device. At the same time, the sensor device contains RGB diodes, an ultraviolet sensor, IR diodes, and a magnetic sensor. In addition, the touch device is configured to compare banknote data with data stored in a storage device including a database containing information about the characteristic features of genuine banknotes, configured to update and replace information, and generate a signal for the control device, and the pressure rollers provide the ability direct and reverse feed of banknotes through the touch device. The technical result consists in increasing the reliability of recognition of both the authenticity of banknotes and the type of their condition (see RF patent No. 135168, publ. 11/27/2013). A disadvantage of the known device is the unsatisfactory reliability of recognition of high quality fakes made using color printers.

In the inventive device at a new technical level, the problem of detecting fake banknotes is solved. Improving the efficiency of detecting counterfeit banknotes is achieved by programmatically checking the quality of the microprint printed on the bill after completing the control of the traditional set of security features of the bill.

The principal difference of the claimed technical solution is the presence in the device of a software-positioned camera-video microscope, which, together with the controller software, provides automatic control of the print quality of micro-fonts and micro-drawing elements at characteristic points specified for each type of Russian banknote.

Disclosure of the essence of a utility model The essence of a utility model is as follows. The desktop version of the detector is intended for mass use at all points of receiving money: - at cash desks of shops, service enterprises and bank branches, and made in the form of a bill acceptor (validator), for installation and mass replacement of existing bill acceptors of the old type in all types banking, vending and payment terminals.

The need for a new detector is explained by the fact that the built-in sensor set of bill acceptors of the early years of release was oriented mainly to a highly reliable automatic determination of the banknote denomination and the identification of roughly made fakes, and therefore is not suitable for detecting modern, very high-quality fakes. The inventive device surpasses the capabilities of the previous generation, since it uses more sophisticated and control methods to identify fakes. Unlike the previous generation detectors, the inventive device is additionally equipped with a built-in, automatically positioned camera-video microscope, which allows, under high magnification, to programmatically evaluate and distinguish the quality of true print on a real banknote from print made on a printer. The criterion for the conclusion about the authenticity of the bill is the sharpness of the print and the absence of a pixel structure in the image of the micro font, symbols and micro lines of the banknote picture in places specified for each type of banknote, problematic for a high-quality fake without the use of special printing equipment and special inks.

The above methods, together with the generally accepted control of the presence and accuracy of the location of metameric marks, ensure compliance with at least four control parameters of banknotes established by the Central Bank of Russia.

The result of the claimed technical solution is a significant increase in the reliability of the conclusion on the authenticity of the checked banknote.

Utility Model Implementation

Verification of the bill consists of two stages. A banknote placed in the receiving tray (1), by the signal of the presence sensor (2) of the tray (1) and the command of the control device (5), is captured by a banknote-pulling mechanism (3) and moves past a set of sensors (6) providing the control device (5) data on the presence and correct location of protective (metameric, magnetic, optical) tags. By the set, shape and position of the protective marks relative to the edge of the banknote, the control device (5) recognizes the side turned for analysis, the position in the direction of movement and the face value of the banknote.

If during the verification it is found that the security features to be checked are not completely present or are not in their proper places, the control device (5) moves the banknote to be checked using the banknote-pulling mechanism (3) back to the receiving tray (1) to return to the owner, while The return process is accompanied by the inclusion of an optical signaling indicator (4) of the corresponding color.

If the security features and the face value of the banknote during the verification are not in doubt, the control device (5) starts the process of determining the authenticity of the banknote using the video camera-microscope (7), which is automatically moved by the electric drive (8) according to the commands of the control device (5) to the predefined areas of the banknote drawing , selected depending on the face value and the banknote side facing the microscope. Aiming the TV camera-video microscope (7) to the specified points of the banknote is carried out by moving the banknote in the longitudinal direction using the bill-pulling mechanism (3) and moving the camera-video microscope (7) over the banknote using the electric drive (8) in the transverse direction. The sections of the banknote intended for verification contain a picture or microtext, high-quality reproduction of which using a printer is impossible and can be automatically detected under magnification using a microscope. In order to conceal the true predetermined banknote control points, the control procedure includes additional microscope movements (7) simulating control in a number of false points.

In the event that the micro-font control procedure passes without comment, the banknote using the bill-pulling mechanism (3) is displayed in the output tray (9) located on the opposite side of the desktop version of the device (from the recipient), or, in the embodiment for installation in payment terminal - to the drive (10). The process of moving the banknote to the drive (10) is accompanied by the transfer of data on the banknote value to the served terminal via the interface (11) and the inclusion of an optical signaling indicator (4) of the corresponding color.

If the quality of the micrograph is insufficient, the bill is pushed back into the receiving tray (1) for repeated attempts to enter the other side, while the return process is accompanied by the inclusion of an optical signaling indicator (4) of the corresponding color.
