Description

The invention relates to the determination and verification of the authenticity of various products using the reading and decoding of bar codes printed on them, including symbolic labels of direct application, with the simultaneous determination of the date, time and coordinates of the scan location using a portable reader (scanner) and can be used when identification of the authenticity of various products - excisable goods (alcohol, tobacco, video products), travel and preferential documents on transport, authenticity of documents ntov identity, including the railways, pipelines, power lines and other long-term and extended objects.

Currently, one of the world's major problems is the protection against counterfeiting of various products of the trading industry and intellectual property such as optical memory devices (DVD, HD-DVD, Blue ray, fluorescent and other optical discs) as well as banknotes, securities, credit cards, documents, etc. This forces the world community to develop a variety of methods and devices to identify and protect against counterfeiting the above elements and products.

The solution to these problems is currently being implemented using, in particular, special brands in the form of one and two-dimensional barcodes, relief holograms or diffraction patterns, radio frequency identifiers and their various combinations. They are applied to the surface or to the volume of the protected object or its packaging.

For reading and decoding applied barcodes (barcodes), various reading devices are used, and in particular, portable reading devices - scanners.

From RU No. 2457537, 10/03/2006, a method for verifying the authenticity or lack of authenticity of a graphically representable machine-readable code consisting of the first unique part that carries no information during its creation and is associated with data in the database, and the second part containing machine read both the first part and the second part of the code, and determining whether both parts of the code are connected, and confirming the authenticity of the code if the two parts are connected, and establishing the lack of authenticity if the two parts are not connected.

The disadvantages of this method include the following:

a) the markings can be copied;

b) each part of the code needs its own reader;

c) is used to verify the authenticity of the barcode, not the product;

d) does not allow to simultaneously determine the date, time and coordinates of the scan location.

From RU No. 2207624, December 27, 2001, a method for determining the authenticity of an object from information about this object is known, which consists in generating information about the protected object in digital form, signing this information with an electronic digital signature of the marker, and forming a digital means for subsequent authentication electronic digital signature of the marker, after which they are converted from a digital form to a barcode, the barcode is applied directly to the object itself or to any tangible medium attached to it and the object, or the one attached to it, and to verify the authenticity of the object, read the barcode, convert it into digital form, extract information about the protected object, the digital signature of the marker and means for verifying the electronic digital signature of the marker, verify the authenticity of the electronic digital signature of the marker, by the result obtained is judged on the authenticity of information about the protected object, after which the authenticity of the information is judged on the authenticity of the protected object, characterized in that as a means To verify the digital signature of the marker, they use a certificate of the public key of the electronic digital signature of the marker, which includes at least information on the public key of the marker, the public key belonging to this marker, signed by the electronic digital signature of the organization that issued the certificate, and as information about the protected object use information that allows you to uniquely determine the authenticity of the object.

The disadvantages of this method: the authentication of the product is carried out by an expert with all the costs and difficulties associated with this, the method does not provide for fixing the time, date and coordinates of the location of the scan.

From RU No. 2213371, 08.10.2002, a method for determining the authenticity of a product is known, which consists in assigning an individual number to an object, which, together with the storage address of the individual key information and object information encoded with it, is converted into a barcode that is applied to the object. At the same time, individual key information and an individual object number are stored at the specified address. When converting a barcode into information, the address and the individual number of the object are highlighted. When contacting this address and entering the individual number of the object, individual key information is issued, with which it is possible to decode information about the object.

A known method and device for the identification of cows (RF patent No. 2423825, application No. 2009143334/21 from 11/26/2009). The method includes recognizing animal numbers, determining the location of the animal and directing them to the desired location. The device contains a thermal imager - an optical-electronic measuring device operating in the infrared region of the electromagnetic spectrum, a thermal imager is connected to an electromagnetic control unit, made in the form of a monoblock and containing a number recognition unit, a signal control unit, an animal location unit, a memory unit and a pairing unit.

The method allows to increase the speed and accuracy of determining a specific animal, but does not allow to read and decode two-dimensional information labels of direct application, for example, on railway cars, pipelines, power lines with real-time fixation and geographical coordinates of the scan location.

Also known is a method of controlling visitors (RF patent No. 2378701, application No. 2008106710/09 of February 26, 2008), which relates to the field of visitor monitoring systems and can be used in various rooms, controlling not only the time of stay, but also determining their location .

The main disadvantages of this method are the impossibility of reading and decoding labels direct application, as well as determining the geographical coordinates of the scan location.

The closest in technical essence and the achieved result is a known method for identifying the authenticity of a controlled object (RU 2132569 13.11.98, C06K 9/00), which consists in the fact that information about the object is generated in digital form, including information about the type of object, manufacturer, production date, individual object number, text information in the form of an accompanying document to the object, sign this information with the electronic signature of the marker, convert it into a bar code and put it on the object or label, with fixed at the facility. When reading information, the bar code is converted back to digital form, an electronic digital signature (EDS) is extracted from it, and then the digital signature is authenticated. If the digital signature is identified as genuine, then the object is authenticated by comparing the read information about the object with the database of genuine objects. If this information matches, then the object is identified as genuine.

However, the use of this method in practice also causes a number of difficulties and does not allow simultaneously with scanning to fix the date, time and geographical coordinates of the area where the scanner is currently located.

The technical task of the claimed invention is to expand the functionality of the method, which improves the efficiency of determining the authenticity of the product when reading and decoding barcodes (barcodes), including symbol labels of direct application (SMPN), on various products, including w / wagons , pipelines, power lines and other remote facilities.

The stated technical task and the technical result achieved are achieved by the claimed method for reading and decoding barcodes, including symbolic labels applied directly to the product with simultaneous fixation of the date, time and coordinates of the scan location, which consists in the fact that each unit of the product is assigned an individual number in alphabetically - in digital form, then the assigned individual number is converted into a barcode containing this number, this barcode is applied to the surface of the product code in the form of marking, enter it into the information database, while reading and decoding barcodes is carried out with the simultaneous receipt and fixing of the current time, date and geographical coordinates of the scan location using a portable reader - a scanner containing a controller with software, including built-in it has a real-time clock with a backup battery that feeds the clock in case of power failure from the main source, and which simultaneously provides decoding setting and fixing the current time and date of the scan and receiver module determining geographical location coordinates of the scanning signals of the satellite navigation system.

When implementing the inventive method, as a portable reader device, a scanner is used, for example, the well-known portable reader for reading and decoding bar codes described in the patent for utility model RU 96992, 08.20.2010, the applicant of this scanner is the same applicant as in the claimed method.

The specified current scanner has a built-in timer module and a receiver module for receiving the geographical coordinates of the area, allowing you to “link” each barcode decoding not only to the date and time, but also to the geographical coordinates of the area where the product is located or is located at the time of scanning .

The following is an example illustrating the claimed method, but not limiting it.

Example

The product is assigned an individual number. The barcode containing this number is applied to the product. In particular, two such barcodes are applied in the form of product marking. The authenticity of the product is determined by the contents of the barcodes and their relative position. The marking consists of a unique digital part that identifies the product and an analog part that protects against counterfeiting. The analog part is determined by the relative position of the bar codes. When decoding, the coordinates of the barcode angles are calculated. Both barcodes are read at the same time. This allows you to calculate the coordinates of the angles of both barcodes in one coordinate system.

When implementing the method, in particular, carry out:

1. Creating a reference.

The product is marked - two closely spaced identical barcodes containing an individual product number. Labeling is scanned, an individual product number and related information about the relative position of barcodes on the product are stored in the database.

2. Carry out a comparison with the standard (determination of the authenticity of the product).

Scan marking of the item under test.

Decoding barcodes and determining their relative position.

Comparison of the relative position of the barcodes of the item under test with the relative position of the barcodes stored in the database under the same individual number as the item being checked.

Make a conclusion about the coincidence / mismatch and the calculation of the probability of error.

When scanning a label for additional information about the time and / or geographical coordinates of the scanning location, the operator scans a special service (command) label. After this execution of such a command, along with the results of decoding the marks, information about the time and / or place of scanning will be present in the memory of the scanning device.

The determination of geographical coordinates and time is implemented by an additional module with a built-in real-time timer (for example, GPS module).

The term "decoding location" refers to the location of the scanner and tags during scanning.

The inclusion of additional information (coordinates + time / date) provides an additional controller with appropriate software that allows you to receive the current time, date and geographical coordinates at the time of scanning. The time and date values are provided by the real-time clock integrated in the controller and a backup battery that supplies the clock in case of power failure from the main source. Coordinates (latitude and longitude with the accuracy provided by the applicable navigation system) are provided, for example, by the GPS receiver module.

For example, coordinates (latitude and longitude with accuracy provided by the satellite navigation system in the zone of its visibility). To obtain the date, time and geographical coordinates, the operator can / must scan the command mark specially designed for this. Next, the operator expects certain light and sound signals confirming the successfully completed process, and the process ends with the recording of the received information in the scanner memory. The inclusion of additional information (coordinates + time / date) provides an additional controller with appropriate software that allows you to receive the current time, date and geographical coordinates at the time of scanning. The time and date values are provided by the real-time clock integrated in the controller and a backup battery that supplies the clock in case of power failure from the main source. Coordinates (latitude and longitude) with the accuracy provided by the satellite navigation system provide a receiver module for determining geographic coordinates from signals from the satellite navigation system with a built-in timer for the current time.

Thus, as follows from the description, this method improves the overall efficiency of determining the authenticity of the product. The claimed method is new, industrially applicable.
