Description

The invention relates to methods for identifying the authenticity of controlled objects and can be used in the identification of excisable goods (alcohol, tobacco, video, etc.).

A known method of identifying the authenticity of objects by marking them with an engraving method and applying a label near the engraving, which is made of an invisible or almost invisible material capable of radiation (according to French application No. 2664073, class 6 06 K 7/10, publ. 1993).

The disadvantages of the method are the high technological complexity of labeling, the impossibility of reliable control of objects by the consumer without special technical means, the difficulty of detecting falsification of objects at all stages of their promotion to consumers.

There are also known methods for identifying the authenticity of controlled objects, for example, the method of applying the marking according to the German application. The carrier of the marking and the method of applying it No. 4231800, cl. 6 09 D 3/00, publ. 1995, on which the carrier is made in the form of a label or label that is attached to the object, and after removing the label, traces of sublimation paint or etching agent applied to a portion of the back surface of the label, or a method for identifying the authenticity of the object being monitored by the author, remain on the object. St. The USSR № 1832318 from 03.05.80, cl. 6 06 K 9/00, based on the introduction into the volume of the carrier identification tags of radioactive substances and fixing it on a controlled object.

The disadvantages of these analogues are the complexity of marking and the negative impact on consumer properties of the controlled object. When using these methods, it is also difficult to control the identification of objects at all stages of their advancement to the consumer.

There is also known a method of hidden marking of material objects, described in the patent of the Russian Federation No. 2107945 from 12.24.96, cl. 6 06 K 9/00, 6 09 G 3/10. In the known method, identification of the authenticity of the object being monitored is carried out by affixing to it labels containing information about the object, using a label carrier fixed on the surface of the object, then reading this information and comparing it with a database of information about authentic objects.

The disadvantages of the above method is the inability to identify the authenticity of the object by the consumer and the low reliability of the identification of the authenticity of the controlled object due to insufficient protection against counterfeiting.

The closest analogue of the claimed invention is a method of identifying the authenticity of a controlled object, described in the patent of the Russian Federation No. 2132569 from 11.13.98, cl. 6 06 K 9/00, 6 07 And 7/00, which is chosen for the prototype. In the known method, information on the production characteristics of the object is formed in digital form and signed by the electronic digital signature of the marker. In the quality of the production characteristics in the method of the prototype use information about the type of object, manufacturer, date of production, the unique number of the object, the accompanying documents to the object. Then the resulting information is converted from digital form into a bar code, which is applied to an object or a label attached to the object. When an object is identified, a barcode is read, it is converted into a digital form, the electronic digital signature of the marker and the information about the production characteristics of the object are extracted from it. Verify the authenticity of the digital signature and information on the production characteristics of the object, the results of which identify the authenticity of the object. In addition, to protect the label from being copied, the method under consideration provides for the possibility of applying a hologram.

With this method, due to the application of information on the label, confirmed by a digital signature (EDS), provides a higher security compared to previously reviewed counterparts.

However, the prototype method has drawbacks:

- identification of the authenticity of the object is based only on the use of special technical means, which is not always possible at the appropriate stages of the object's movement to the consumer, and, therefore, the required completeness of coverage of control is not provided;

- the complexity of verifying the authenticity of EDS associated with the need to record, store in a computer memory block or on another medium public key and deliver it with each object authentication, as in the prototype method there is no provision for labeling the public key without which it is impossible to verify the authenticity EDS and information on the production characteristics of the object printed in the bar code;

- a relatively low probability of detecting tampering with unauthorized manufacture, reuse of labels and labeled containers, replacement of accompanying documents, etc. without the use of special technical equipment at all stages of the promotion of the object from the manufacturer to the consumer. This is due to the fact that the information on the label in the form of a bar code is not available for the usual visual reading, which limits the ability of the supplier, recipient and consumer to verify it with the real object and / or information specified in the accompanying documents.

The technical result of the claimed invention is to provide a method that simplifies the verification of authenticity of digital signature and information about the production characteristics of the object printed in the bar code, reducing the likelihood of falsification of the object at all stages of its promotion from the manufacturer (marker) to the consumer while maintaining a high degree of security of all information, printed on the label, without additional economic costs.

The formulated technical result is achieved by the fact that in a known method of identifying the authenticity of a controlled object, namely, that they generate information about the production characteristics of an object in digital form, sign it with an electronic digital signature of the marker, convert the received information from a digital form into a bar code, put a stroke - the object code or label attached to the object reads the bar code, converts it into digital form, extracts the digital signature of the markers from it ik and information on the production characteristics of the object, verify the authenticity of the digital signature and information on the production characteristics of the object, the results of which identify the authenticity of the object, additionally add the public key of checking the digital signature to the bar code, form information about the parameters of the consumer properties of the object and the parameters of the manufacturer of the object form of alphanumeric text. Simultaneously with the application of a bar code on an object or a label attached to an object, an alphanumeric text is written on the parameters of the consumer properties of the object and the parameters of the manufacturer of the object. Moreover, when reading a bar code, the public key of the EDS verification is used, which is used to verify the authenticity of the EDS, and the identification of the object based on the authentication of the electronic digital signature of the marker and information on the production characteristics of the object is supplemented by verification of the authenticity of the object by comparing information on the parameters of the consumer properties the parameters of the manufacturer of the object, applied to the object or the label attached to the object, with the actual parameters of the consumer object properties and parameters of the manufacturer, and provided that they meet the object is identified as an authentic combination of authentication of digital signatures, information on production characteristics of the object, as well as the parameters of consumer properties of the object and the object parameters manufacturer.

As the parameters of the manufacturer of the object using the region code, the manufacturer code, the application number for the production of a serial batch of objects and the number of the object in the serial batch.

As parameters of consumer properties of objects, parameters controlled visually, by touch, by weight, color and smell are used.

As production characteristics, use the region code, the code of the marking organization, the manufacturer code, the supplier code, the type of the object, the date of manufacture, the application number for the production of a serial batch of objects, the number of the object in a serial batch.

Thanks to a new set of essential features, it is easier to verify the authenticity of EDS and information on production characteristics by including the public key in the barcode, since it does not need to be written, stored or delivered.

As a result of the application of alphanumeric text on the label, the object is protected from possible falsification. This is achieved due to the fact that, in addition to instrumental control, it is possible to document and user control of the object by any interested person at all stages of the promotion of the object from the manufacturer (marker) to the consumer without the use of technical means.

Due to the combination of alphanumeric text and barcode on the label, as well as duplication of information displayed in alphanumeric text and information in a barcode protected by a cryptographic method, a high degree of security of all information printed on the label is maintained.

The introduction of a public key verifying the EDS and additional alphanumeric text does not alter the cost of making the label and does not require additional economic costs for monitoring.

The analysis of the level of technology has allowed to establish that the analogues, characterized by a set of features identical to all features of the claimed technical solution, are absent, which indicates the compliance of the claimed device to the condition of patentability "novelty."

Search results known solutions in this and related areas of technology in order to identify signs that match the distinctive features of the prototype features of the declared object, showed that they do not follow explicitly from the prior art. The prior art also revealed no prominence of the effect of the transformations envisaged by the essential features of the claimed invention on the achievement of the said technical result. Therefore, the claimed invention meets the condition of patentability "inventive step". The claimed method is illustrated by drawings:

FIG. 1 - the appearance of the label for alcoholic beverages;

FIG. 2 - the appearance of the label for tobacco products;

FIG. 3 - the appearance of the label with a holographic label. Promotion of the object to the consumer occurs in several stages:

registration of permits for production, production proper, execution of accompanying documents, delivery of an object to wholesale bases and to a retail distribution network, and, finally, realization of an object to a consumer. To identify the authenticity of the object it is labeled with a protected label. However, at all these stages there is a possibility of falsification and replacement of the object.

According to the method known from the prototype, manufacturers request the required number of protected labels from an authorized organization. Labels are applied with a bar code with information on the production characteristics of the object protected by EDS. It is assumed that at the factory these labels are fixed exactly on the specified types of objects. However, to obtain certain benefits or due to errors at the factory, protected labels can be attached to other types of objects. For example, labels ordered for low-cost objects are fixed to expensive objects or vice versa. The manufacturer does not have the ability to verify compliance of the attached labels with objects without the use of special equipment due to the fact that information about the object is printed on the label only in a bar code that is inaccessible for ordinary visual reading.

A similar situation arises when delivering objects to wholesale bases and to a retail distribution network. At this stage, when drafting the accompanying documents, it is possible that the information on the manufacturer, supplier and type of product, including its deliberate distortion, may be incorrectly indicated. According to the information on the label, forgery and errors in the accompanying documents without special technical means cannot be opened. The use of conventional factory product labels for this purpose is ineffective, due to their low protection against forgery or the usual substitution. For the same reason, the consumer is not able to identify the authenticity of the object by the parameters of consumer properties of interest to him. The presence or absence of a label on the object with information in the barcode for the consumer is not significant, as it does not have the ability to read it.

It is possible to reveal attempts of falsification in various ways, for example, having taken the following measures:

- equip all officials who have access to the object with special technical means of control described in the prototype method;

- to increase the vigilance and discipline of personnel at all stages of the promotion of the object to the consumer, to introduce enhanced security measures, and so on;

- to provide access for the mass consumer to instrumental control and to achieve 100% coverage of objects by instrumental control, etc.

However, the implementation of these measures is difficult, since it requires substantial economic costs that may exceed the costs of producing and selling the objects of protection themselves.

The inventive method is as follows.

Manufacturers send an application to the authorized organization for the production of the required number of protected labels. In the application indicate the following information:

- labeling organization, manufacturer, supplier (for example, their names, codes, legal and actual addresses, TIN, etc.);

- type of object (for example, its name and state registration code);

- date of manufacture;

- packing capacity;

- consumer properties (for example, alcohol content, taste, color, aromatic additives, etc.);

- application number and date;

- batch number and number of objects in the batch;

- information on accompanying documents (for example, the number of the certificate of conformity, the number of the quality certificate, the number of customs documents) and other necessary information.

In the authorized organization for each controlled object form

1) information about the object, including data from the application, which is placed in the database of authentic objects;

2) information on the production characteristics of the object in digital form;

3) information about the parameters of the consumer properties of the object and the parameters of the manufacturer of the object - in the form of alphanumeric text;

4) public key verification of digital signature in digital form.

As in the prototype, performance information is signed

EDS generated on the basis of a private key using a cryptographic algorithm implemented in accordance with the requirements of GOST R 34.10-94. For this you can use, for example, the software tool for cryptographic information protection Sgur1opAgsMay, developed and commercially supplied by the company ANKAD Moscow, publ. in Yu.V. Romanets, P.A. Timofeev, V.F. Shangin, “Information Security in Computer Networks,” M .: Radio and Communications, 1999, p. 282. Then information on production characteristics, digital signature and public key of verifying the digital signature are converted into a bar code, for example, into a two-dimensional bar code of the type MicroREG-417, which is simultaneously printed on the label with alphanumeric text.

Thus, the label displays information in the form of alphanumeric text and in the form of a bar code (Fig. 1).

The alphanumeric text include

- information on the parameters of consumer properties, determined visually, by touch, by weight, by color and smell. For example, for alcoholic beverages - this is its name (“Absolut Vodka”, “Jubilee Cognac”, etc.) and bottle capacities (“0.75l”, “0.5l”, “0.25l”, etc.), for tobacco products (Fig. 2) - the name (Cigarettes with filter "Troika", "Cigarettes Amateur", etc.), special properties ("flavored", "menthol", etc.), the number of cigarettes in a pack ;

- information about the parameters of the manufacturer of the object in a code-digital form, including the region code (for example, in the form of a two-digit number "60", "12", etc.), the manufacturer's code (for example, in the form of a four-digit number), application number for production of a serial batch of objects (for example, a six-digit number) and an object number in a serial batch (for example, a six-digit number). Region codes in the Russian Federation are defined at the federal level and coincide with the codes used, for example, in the vehicle number registration system. The codes of manufacturers (plants) in the Russian Federation are established by the Foreign Economic Association for Automatic Identification UNISCAN, as indicated, for example, in the journal Standards and Quality, 1994, No. 3, p.54. The application number for the production of a serial batch of objects and the object number in a serial batch are determined by the organization that prints the protected labels and keeps their number registration.

The barcode displays the following information about the performance characteristics:

- type of object (for example, name and state registration code, packing capacity (mass) and other consumer parameters);

- codes of region, manufacturer, labeling organization, supplier;

- the date of manufacture of the object;

- serial lot number (corresponds to the application number);

- object number in the serial lot.

Information about the production characteristics contains information about the parameters of consumer properties of the object and the parameters of the manufacturer of the object, which is also displayed in alphanumeric text.

In addition, the barcode includes a digital signature and a public key to verify it.

Conversion of information into a bar code is implemented, for example, using the software module Apech Tok South of REG 417 (Aph 417) version 1.61, developed by Apech Tesposche 5 1ps., Sapaba. The specified module allows you to convert into a bar code information containing up to 2000 bytes, which is quite enough for the implementation of the proposed method. In the proposed technical solution, the conversion to a bar code is subject to information of no more than 650-660 bytes, including EDS (98 bytes), public key verification of EDS (256 bytes) and information on production characteristics (not more than 300 bytes).

Printing alphanumeric text and a barcode on a label can be done, for example, on a standard Tiai 6200 type printer manufactured by EaMamax 1 ps. USA, also, as indicated in the description of the prototype. The process of printing alphanumeric text is carried out simultaneously with the printing of a bar code and, therefore, it does not require additional time and financial costs.

Due to the duplication of information in alphanumeric text and information in a bar code protected by EDS, high security of information in alphanumeric text is provided. Any distortion of information in the alphanumeric text will be detected when reading a bar code and then verifying the digital signature. To protect against copying, you can apply a holographic tag with hidden images and microtexts on the label (Fig. 3).

Printed labels are sent to the manufacturer (marker), which attaches them to objects, for example by gluing, in accordance with the application submitted and with the information contained in the alphanumeric text. The correctness of this operation can also be monitored by comparing the information on the label with the information given on the usual factory product label.

In the future, at all stages of the promotion of the object in the accompanying documents indicate information about the object, manufacturer, region, number of the serial batch of objects and the number of the object in the serial batch and indicate their conditional codes similar to those indicated on the label in alphanumeric text. The accompanying documentation, for example, may include a waybill, an invoice, a copy of the certificate of conformity, etc.

Suppliers, representatives of trading organizations and consumers identify the authenticity of the object by reading the alphanumeric text and comparing it with the actual parameters of the object and with information from the accompanying documents. The discrepancy between the declared parameters and those found on the object makes it possible to reveal its unauthenticity. The possibility of such a check by any person without special technical means at all stages of the advancement of an object reduces the likelihood of falsification of the object and accompanying documents.

The instrumental control of the authenticity of the object is carried out by reading the bar code and converting it into digital form using a scanner, for example, type IV8B ΡΌΕ produced by IV8 CVr. Emit an EDS, a public key verifying an EDS and information about the production characteristics of the object. Verification of the authenticity of EDS using the public key is carried out in a computer using a cryptographic verification algorithm (GOST R 34.10-94). According to information about the production characteristics, in particular, by the application number, information about the object is read from the database of information about authentic objects and compared with the parameters of the object being monitored. The authenticity of a hologram can be checked, for example, using a device for checking latent images produced by the State Unitary Enterprise NTT Atlas, Moscow, and reading microtexts - using, for example, a 30-fold contact microscope of the company M1kko.

Thus, in the claimed method, depending on the stage of advancement of the object and the presence (absence) of technical means, the identification of the authenticity of the object is carried out by three types of control: instrumental, documentary, user-defined, or their combination.

Instrumental control assumes that the controlling person has the technical means of control (scanner and computer - laptop). The object is checked instrumentally by the authenticity of the EDS, comparing information on production characteristics with a database of information about authentic objects, as well as visually comparing all the information received, including that printed on the label in alphanumeric text, with the object being monitored. The authenticity of the hologram can also be verified using the appropriate device by visualizing latent images and microtexts.

In documentary control, interested parties (manufacturers, suppliers, recipients, etc.) who do not have special technical means, control objects according to manufacturer’s parameters and consumer properties, comparing the information contained in the alphanumeric text on the label with information from accompanying documents.

With user control, consumers compare visually, touch, weight, color and smell the actual consumer properties of the controlled object with the parameters declared on the label in alphanumeric text. For example, alcoholic beverages are controlled by color, bottle capacity, strength, etc., tobacco products by type of cigarettes (with a filter, without a filter), the number of cigarettes in a pack (the number of packs in a block package), the smell of flavoring additives, etc. P.

Verification of the authenticity of the object is carried out with positive results of the checks. If there is a discrepancy in the controlled information, then the object is identified as non-genuine.

The technical solution claimed as an invention eliminates the need for recording, storing and delivering public keys for verifying EDS and provides for the possibility of instrumental control of the object using special technical tools, as well as documentary and user control at all stages of its promotion from the manufacturer (marker) to the consumer. Provides a high degree of security of all information printed on the label. The probability of detecting falsification of an object without attracting additional economic costs increases.
