Description

The invention relates to the field of manufacturing and marketing of products (items) of serial production for any purpose and can be used in shorthand to protect against unauthorized use and counterfeiting products with a digital or barcode, for example, such as various documents, medicines, food products, various printing products , as well as other items that have primarily a paper medium.

A known method of protection against counterfeiting of mass-produced products, including applying to the surface of the labels, or on the surface of the strips of material, or on the surface of other types of media that attach to the products, their packaging and / or packaging, an individual identification number of the protection, hidden from free reading of the protective film and collapsing to the extent that excludes the possibility of its unambiguous reading when removing the media on which it is applied, or violating the integrity of the media, and functionally designed started to determine the authenticity of products by comparing the read individual protection identification numbers with copies of the individual protection identification numbers stored in the manufacturer’s database, as well as by establishing the mutual correspondence of the read individual protection identification numbers of the products, their packages and / or containers with copies of such correspondence, also stored in the manufacturer’s database, while the individual protection identification number contains a regular part that determines Seed lot number produced under a specific brand name products, and irregular statistically random, non-repeating within one of the party that is assigned to each product batch on the basis of the method of forming the random number or through the use of random number tables (RU, 2225641).

The limitation of the method is the need to use a protective film, eliminating the possibility of an unambiguous reading of the identification number when removing the media, which requires the constructive processing of all products or products of serial production.

There is a method of protecting an object from unauthorized use and forgery, which consists in the fact that the surface of the sheet is encoded with images of the same marks, which are successively applied to the surface of the sheet (RU, 2256225).

In this known manner, an article is made with an encoding template containing a plurality of marks, each of which represents one of at least two different values, and a plurality of nominal positions, each of said plural marks being associated with one of the said plurality of nominal positions, and a value each label is shown by its location relative to its nominal position, while the coding template contains a raster with raster lines, where the intersections of the raster lines specify the nominal location tags (RU, 2256225).

In this technical solution, the marks are made the same, and the coding is carried out by shifting the marks relative to the nominal position.

Thus, it is known a device for protecting an object from unauthorized use and forgery, containing a sheet, image labels made on the surface of the sheet alternately one after another in rows (RU, 2256225).

The advantages of this technical solution are:

- marking the surface of the sheet so that they do not interfere with reading other printed information printed on the surface of the sheet, visually observed, and which is intended for the consumer;

- coding can be carried out over the entire surface of the sheet, which improves the reliability of protecting the product from unauthorized use or forgery, since the labels cannot be removed unlike a digital code (or barcode), which is usually located only on part of the sheet, usually on its periphery, or for this often use a sticker.

The limitations of this technical solution are:

- the need for accurate positioning of the same labels relative to the intersection of raster lines that specify the nominal position of the labels;

- the complexity of reading encoded information, because this requires special optical devices that determine the position of the same label relative to visually unobservable - nominal;

- the possibility of errors when reading encoded information and the complexity of manufacturing products due to the need for very accurate positioning of labels;

- the ability to arrange labels only relative to raster lines that form a rectangular (square) grid or rasters in the form of triangles or hexagons, i.e. relatively only horizontal and vertical directions.

The problem solved by the invention is the improvement of technical and operational characteristics.

The technical result that is achieved during the implementation of the method is to increase the reliability of protection, the ability to decode information visually, without the use of optical devices, eliminate errors during decoding.

The technical result that can be obtained by performing the claimed device is to increase the reliability of protection, simplify the manufacture of products and eliminate defects in its production, the ability to decode information visually, eliminate errors during decoding, the ability to place labels in any direction of their row location.

To solve the problem with achieving the specified technical result, the method of protecting the object is that the mathematical number of the digital code of the object in the decimal number system is converted by rebuilding the location of the digits of the mathematical number, remember this rebuilding and the rebuilt mathematical number itself, then the rebuilt mathematical number is converted from decimal numeral systems to quadruple, and the converted mathematical number in the quadruple numeral system is encoded for I of its four digits with images of unequal marks, which are applied one after another on the surface of the sheet, sequentially with images of unequal marks, repeat the encoded converted mathematical number in the quadruple number system at least two times, and divide the mentioned images of unequal marks with initial images labels denoting the initiation of a mathematical number in a quadruple number system.

- the sheet was made of paper, or of a polymeric material, or of fabric;

- the mathematical number of the digital code in the decimal number system was the mathematical number of the object - document number, or inventory number, or identification number.

To solve the problem with the achievement of the specified technical result in a known device for protecting an object from unauthorized use and falsification, containing a sheet, image marks made on the surface of the sheet alternately one after another in series, according to the invention, the image labels are made unequal, with some following other images of unequal labels in a row are sequentially repeated at least two times.

Since the claimed method receive the claimed device, its detailed description is given in the description section of the operation of this device.

A device for protecting an object from unauthorized use and falsification (FIGS. 1, 2) comprises sheet 1, images of 2 marks made on the surface of sheet 1, alternately in series by rows 3. Images of 2 marks are made unequal. A part of the successive images 2 of unequal marks in row 3 is sequentially repeated at least two times. Images of 2 unequal marks fill most of the surface of sheet 1.

Images of 2 unequal marks can be made on the surface of the sheet in horizontal rows 3 (Fig.1, 2).

Images 2 of unequal marks can be made on the surface of the sheet in vertical rows 4 (figure 3).

Images 2 of unequal marks can be made on the surface of the sheet with inclined rows 5 (figure 3).

Images of 2 unequal marks can be performed on the sheet surface in rows of 6 in the form of sinusoids (Fig. 3) or other trigonometric functions.

Images of 2 unequal labels are triangles (FIG. 1), and / or rectangles (FIG. 4), and / or ellipses, and / or letters of the alphabet, and / or images of stars with different numbers of ends (FIG. 2), and / or images of flowers with different numbers of petals (figure 4), etc.

Sheet 1 can be made of paper (for example, a document or a label), or of polymeric material (for example, a driver’s license, packaging, label), or of fabric (for example, a canvas of an artwork on which images of 2 marks are applied from its back )

The mathematical number of the digital code in the decimal number system can be the mathematical number of the object - the document number (for example, passport, driver’s license, USE form (Fig. 1, 2)), or inventory number (for example, pictures), or identification number (for example, taxpayer).

The device (figure 1, 2) operates as follows.

A document with enhanced security is being prepared. By the document in the present invention is meant any physical information carrier on a paper, plastic, fabric and other basis. Sheet 1 of the document may be with or without a digital code. The digital code can be a service numerical number and a barcode.

The method allows for the secret transmission of service information by encoding a document with images of 2 unequal labels by keeping secret the very fact of information transfer and with the possibility of subsequent identification and recognition of service information in print and electronic formats.

Images of 2 unequal labels can be various geometric shapes, patterns, graphic elements (figures 1, 2, 4), etc.

The stages of the method (figure 5).

1. The mathematical number of the object’s digital code in the decimal number system is transformed by the function Y = F (x) by rebuilding the location of the digits of the mathematical number, remember this rebuilding [Y = F (x)] and the rebuilt mathematical number itself.

2. The rebuilt mathematical number is converted from a decimal system (SS) to a quadruple (SS).

3. The converted mathematical number in a quadruple SS is encoded for its four digits with images of 2 unequal marks, which are successively applied to the surface of the sheet 1.

4. Sequentially, with images of 2 different labels, the encoded converted mathematical number in a quadruple SS is repeated one after another at least two times (FIGS. 1, 2, 5), while the images of 2 different labels are divided up with 7 initial labels representing initiation mathematical number in the quadruple number system (Fig.7).

An example implementation of the method.

Stage 1.

Let the digital number of the digital code of the object be

We divide the digital number into separate digits:

1st = 0

2nd = 7

3rd = 8

4th = 5

5th = 0

6th = 0

7th = 1

Rebuild the location of the digits of a mathematical number to obtain an encryption key. The point is to mix the numbers according to the algorithm specified by the developer (i.e., swap the first digit with the fourth, swap the third digit with the seventh, etc.):

получим новое число, равное D=5001708For the mathematical number of the digital code

we get a new number equal to D = 5001708

1st = 5

2nd = 0

3rd = 0

4th = 1

5th = 7

6th = 0

7th = 8

2 stage.

Convert from decimal CC to Quaternary CC.

Decimal number D is divided by 4. The remainder is B ₀ . The quotient is again divided by 4. The remainder is B ₁ . Repeat until we get 1/4 = 0 with remainder 1. This last remainder is the highest unit.

5001708: 4 = 1250427, remainder B0 = 0

1250427: 4 = 312606, residue B1 = 3

312606: 4 = 78151, remainder B2 = 2

78151: 4 = 19537, remainder B3 = 3

19537: 4 = 4884, residue B4 = 1

4884: 4 = 1221, remainder B5 = 0

1221: 4 = 305, residue B6 = 1

305: 4 = 76, remainder B7 = 1

76: 4 = 19, remainder B8 = 0

19: 4 = 4, remainder B9 = 3

4: 4 = 1, remainder B 10 = 0

1: 4 = 0, remainder B11 = 1

As a result, from 5001708 in decimal CC, we get 103011013230 in quaternary CC.

3 stage.

The converted mathematical number in the quadruple CC is encoded for its four digits with images of 2 unequal marks, which are successively applied to the surface of the sheet 1.

For example, the selected images of 2 labels for a number in a quadruple SS are shown in the table (Fig.6).

Using the conversion table (Fig. 6), we obtain a symbolic interpretation of the quaternary code in the form of triangles (Figs. 5, 7).

The mentioned images of 2 unequal marks are divided into images of 7 initial marks (Fig. 7), indicating the initiation of a mathematical number in the quadruple number system.

Decoding is performed in the reverse order (Fig. 8).

Stage 1.

Images 7 of the initial marks are determined (Fig. 7) and the initiation of the mathematical number in the quadruple number system begins.

Images of 2 marks (triangles) in accordance with the table (Fig.6) are converted into a quadruple CC. Get 103011013230 (Fig.8).

2 stage.

Convert from Quaternary to Decimal CC.

To translate a number into some number system with a base M (digits 0, ..., M-1), in other words, into an M-ary CC, you need to represent it in the form:

C = a _n * M ⁿ + a _n-1 * M ^n-1 + ... + a ₁ * M + a ₀ ,

where a _{1 ... n} - digits of a number from the corresponding range; a _n is the first digit; a ₀ is the last one.

C = 103011013230

C = 1 * 4 ¹¹ + 0 * 4 ¹⁰ + 3 * 4 ⁹ + 0 * 4 ⁸ + 1 * 4 ⁷ + 1 * 4 ⁶ + 0 * 4 ⁵ + 1 * 4 ⁴ + 3 * 4 ³ + 2 * 4 ² + 3 * 4 ¹ + 0 * 4 °.

As a result, we get the mathematical number in decimal CC-C = 5001708.

3 stage.

The inverse transform to find the original mathematical number of the digital code of the object

We apply the inverse transformation function for C = 5001708:

1st: 0

2nd: 7

3rd: 8

4th: 5

5th: 0

6th: 0

7th: 1

The initial mathematical number of the digital code is 0785001. Therefore, all the transformations are carried out correctly.

In figures 1 and 2, as an example of documents with increased security, the forms of a unified state exam (USE) are shown. The mathematical number of the digital code and the barcode are located on the fields of the forms so as not to interfere with the reading of tasks. These codes can easily be deleted by photocopying the forms, and then it is not possible to understand where the information leak came from. Drawing an array of images of 2 labels practically does not affect the reading of the text of tasks, but allows you to restore the digital code from them. Images 2 labels in figures 1 and 2 are shown very clearly for understanding the essence of the invention, in fact, they can be made dim, barely distinguishable.

Thus, it is possible to increase the reliability of protection by eliminating the strictly positioning of images of 2 tags, to provide the ability to decode information visually, without the use of optical devices, to simplify the manufacture of products and increase the yield of products, to provide the ability to arrange tags in any direction of location of their rows.

The most successfully claimed method and device are industrially applicable in shorthand for transmitting service information by encoding a document with special characters by keeping secret the very fact of transmitting information and with the possibility of subsequent identification and recognition of service information in print and electronic formats.
