Description
METHOD FOR VERIFYING THE AUTHENTICITY OF DOCUMENT
The invention relates to methods for verifying the authenticity of different securities containing identification elements, with preliminary control testing and can be used for determining the authenticity of documents which are assigned individual signs, for example, numbers, bar codes etc.
The real approach to the matter of protection of banknotes, securities and other important documents shows that 100% avoidance of counterfeiting thereof is impossible. However, control of such harm is carried out by different ways, including by perfection of processes for verifying the authenticity of documents.
There are known the methods for verifying the authenticity of banknotes, financial documents and other securities, into which one of the identification elements attesting the authenticity of product is the texture of material thereof.
These methods are based mainly on show through of the verified documents in the regime of light beam scanning modulated during passage through the document by the inner texture of material. The physical parameters of the transmitted radiation are converted into the digital code of the document material texture.
One of such methods is the method for verifying the authenticity of banknotes and other financial documents based on measurement of two independent individual space-extended features of the processed document, one of which is determined by the paper production technology and the other - by the polygraphic document printing method [I].
In the process of realization of the given method the document surface is irradiated with two scanning optical beams with different wavelengths. The document is showed through with one beam, and the transmitted light flux is converted into the first electric signal and it is formed the first digital code constituting the feature of the texture of paper. The other beam is reflected from the document surface and the reflected light flux is converted into the second digital code constituting the printing feature of the document. Between the first and the second codes there is created a digital combination used for comparison with the reference value obtained during the control testing of the document.
The control testing is carried out during document printing performing the same operations and in the same succession as during verification of its authenticity. The reference value is saved in the created database of the identification system and is used further on for comparison with the
value obtained in the verification process. The comparison result establishes the authenticity of document at the value coincidence and counterfeit thereof- at noncoincidence.
The disadvantage of the described process consists in the high realization complexity thereof. In order to perform all verification procedures it is necessary to use a lot of special technical means: laser radiation sources, radiation detectors, scanners, analog-to-digital converters, analyzers, synchronizers etc.
At the same time, the potential failures in the process of operation of numerous electronic devices constituting the circuitry of the process reduce the operational reliability of the device and, therefore, the reliability of realization of the performed process.
The closest by the technical essence to the claimed invention is the method for controlling the authenticity of documents described in the international application N° WO 9523388 [2]. hi the given method verification of the authenticity of document, having at least one individual identifying sign, is carried out by means of reading, particularly scanning and/or photographing with the help of optical appliance by a device on base of photosensor, at least of one specified part of the document, containing figurative elements used for identification and an individual identifying sign, recordings, in pixels, of the light flux intensity reflected by the part with figurative elements and individual identifying sign, retention similarly of the recorded information of the original document in the database of the document identification system, use of an individual identifying sign as document address in the database of the identification system, automatic or manual comparison of at least one selected for verification specified part with figurative identifying elements of the verified document with the corresponding part of the original document contained in the database of the identification system, at the same time the part with figurative identifying elements is placed in the same place of the document with respect to the individual identifying sign.
Each recorded specified part of the document contains two pixels, the figurative pattern thereof is digitized, and each pixel is specified in the shape of bit chain corresponding to the reflected light intensity.
The achievement state-of-the-art in the high technology field permits to manufacture counterfeit documents with high degree of accuracy, particularly to perform a high-grade counterfeit of any figurative patterns applied on the document, as well as to take into account the intensity of the reflected therefrom light flux.
As a result of this the main disadvantage of the described method consists in the insufficiently high degree of certainty of identifying the authenticity of the verified document, limited by the use as identification criterion of distribution of the light intensity reflected by raster points of the figurative pattern, situated on the selected for verification part of the document.
Moreover, the given method resides disadvantages peculiar to the earlier described analogue. The problem undertaken by the author of the invention consists in elaborating a sufficiently feasible and reliable verification method providing a high degree of certainty of identifying the authenticity of document.
The undertaken problem is solved at the expense of the fact that in the proposed method for verifying the authenticity of document, having at least one individual identifying sign, carried out by means of reading, particularly scanning and/or photographing with the help of optical appliance by a device on base of photosensor, at least of one specified part of the document, containing figurative elements used for identification and an individual identifying sign, recordings, in pixels, of the light flux intensity reflected by the part with figurative elements and of the individual identifying sign, retention similarly of the recorded information of the original document in the database of the document identification system, use of an individual identifying sign as document address in the database of the identification system, automatic or manual comparison of at least one selected for verification specified part with figurative identifying elements of the verified document with the corresponding part of the original document contained in the database of the identification system, in addition the part with figurative identifying elements is placed in the same place of the document with respect to the individual identifying sign, the part of the document selected for verification is scanned with a resolving capacity no less than 600 pixels per inch, and as figurative identifying elements is used the surface relief of the chosen for verification part and/or pattern, formed on the relief during the dye contact with the surface.
At the same time, the individual identifying sign represents a visually accessible for man random or specified combination of printed characters, for example, letters, and/or numbers, and/or bar codes.
The specified part of the document includes at least part of the printed character of the individual identifying sign and/or part of the adjacent zone, as well as can represent a geometric figure of arbitrary shape placed in the arbitrary place of the document and/or part of the adjacent zone. As material of the document is used paper, and the longitudinal dimension of the document part containing figurative identification elements is specified much greater than the cross dimension of the paper fiber.
The document is made in the shape of an identification means representing a complete product, and means constructively joined with the product with the impossibility of separation without being disturbed the integrity of the document, and/or product, and/or lockup.
The result obtained at the realization of the present invention consists in increasing the degree of certainty of verifying the authenticity of different documents by means of a more simple and reliable method.
As everybody knows, the paper, including that used for manufacture of documents, possesses a specific fibrous structure determined by the process of manufacture thereof. Said structure is random for each copy of document, randomly being formed not only the inner texture of paper, but also the aspect of its surface. The surface fibers as both the individuality of placement and the uniqueness of its surface shape create a unique three-dimensional relief variable for a certain document from part to part, of any arbitrarily chosen specimen paper, however visually small the part dimension is chosen. To reproduce such a relief by up-to-date methods is practically impossible.
The expected result is provided due to the fact that as figurative identification elements it is proposed to use the surface relief of the previously specified part of document. At that, if on the area of the specified part are situated any printed characters, than as figurative identification elements is used the pattern formed on the relief during the dye contact with the document surface.
If by chance on the chosen for verification part of document are situated both the printed characters and the clean zone free from printed characters, than as identification elements are used both the surface relief of the clean zone and the patterns obtained on the relief at the interaction of the dye used for printed characters with the material fibers. The obtained pictures as if supplement each other. The possibility of visually obtaining pictures of the document surface relief can be attained when scanning the chosen part with resolving capacity no less than
600 pixels per inch.
Indeed, when reading, particularly scanning and/or photographing with the help of optical appliance by means of a device on base of photosensor of the product with resolving capacity of
600 pixels per inch, the pixel dimension constitutes 0,04 mm, which approximately corresponds to the paper fiber thickness upper value which on average is located in the range from 0,01 up to
0,04 mm. Thus, beginning with the indicated resolving capacity, it is overviewed the paper surface structure with coarse fibers.
Besides, during the elaboration of the claimed method it was experimentally demonstrated that the surface relief of certain types of paper is overviewed beginning with the resolving capacity of
600 pixels per inch.
The freely used up-to-date scanners provide a resolving capacity in the range of defined numerical values: 75,100,150, 200, 300, 400, 600,1200 etc. pixels per inch, and, for example, the digital microscopes or even the mobile phones with integrated cameras when shooting via the
pocket microscopes exceeds by far this minimum level of resolving capacity. The proposed method permits to make the best use of small surface parts and as a result the files are small which is fundamentally important in both the creation of corresponding databases and the data transfer over the Internet.
Use for realization of the proposed method of a limited number of widely available commercial electronic devices makes it simple and reliable.
Thus, the claimed method for verifying the authenticity of document is usable, provides a high degree of document authenticity control certainty, and its realization does not need great material, financial and labour expenditures.
Summary of the invention is explained by the following description and drawings representing: fig. 1, general view of the verified document, in the capacity of which it is used an excise mark for wine production; fig. 2, part of document fig.1 chosen for verification.
The verified document 1 (fig. 1) comprises a serial number 2, being the identifying sign of the document, placed around it a zone 3, free from printed characters, and a bar code 4. On the serial number 2 there is marked out for verification a previously specified part 5, containing three figures of the number - 8, 8, 5 and the part of zone 3 placed around them.
In fig. 2 it is shown the part 5 on an enlarged scale, obtained during the resolving capacity of the scanning device of 600 pixels per inch which occupied only 12 kilobytes. On this part there are situated figurative identification elements 6, representing the surface relief of the marked out part of zone 3, and figurative identification elements 7, representing patterns formed on the relief at the expense of contact with the surface of document 1 of the dye used for application of the serial number 2.
The proposed method for verifying the authenticity of document consists in the following. On the paper surface is applied a defined installed for the given document pattern, the required information data and an individual identifying sign, visually accessible for man. As identifying sign is used a random or specified combination of printed characters, for example, letters, and/or numbers, and/or bar codes. Usually the identifying sign is the serial number 2 of the product and/or its bar code 4 (fig. 1) applied by means of the chosen dye. The application of dye is carried out by means of an inkjet or laser printer, by manual method or any other known method.
On the original document it is selected a part, containing figurative identification elements, which later on will be overviewed as a reference specimen.
Such part can be the part 5 (fig. 1, 2) containing the part of the serial number 2 and the part of the free zone 3. Moreover, such part can be any part on the surface of the document limited in
any way, for example, by a geometric figure of arbitrary shape: circle, rectangle, triangle etc. and/or the part of the adjacent zone.
As a rule, for the manufacture of different documents is used paper satisfying the established for the given document composition and density requirements. The features of the material fibrous structure of the used paper define the specific unique relief of its surface. At a defined increase the relief, created by the fibers and the binding composition, appears in the shape of a three- dimensional picture.
The selected part of the document, containing a special individual aspect of the surface relief (elements 6 and 7 fig. 2), is read with the resolving capacity of the used device of at least 600 pixels per inch. In the database of the document identification system, created by the manufacturer, it is recorded in pixels the light flux reflected by the given part. At the same time it is concomitantly read and recorded in the database the identifying sign, for example, the serial number 2 (fig. 1). The identifying sign is the name of file wherein in the database it is stored the information on a certain document, and the access thereto is provided by different up-to-date communication means, for example, over the Internet with the help of the mobile telephone communications etc.
In order to obtain a legible readily cognate picture of the selected for identification part surface relief its longitudinal dimension must be much greater than the cross dimension of the paper fiber, in order that thereon may be placed at least several fibers.
For the suitable orientation and quick finding on the document surface of the selected for verification part, said part is situated in the specified place with respect to the individual identifying sign.
In case of scanning with a resolving capacity providing the legible visualization of a separate fiber, as figurative identification elements there can be used the relief of its surface. During verification of the authenticity of document from the database of the document identification system according to the file name it is extracted the image of the part surface relief, being the reference specimen, and it is compared with the image of the analogously placed part on the verified document. At that, the part of the verified document is also read with the corresponding resolving capacity (no less than 600 pixels per inch) and is recorded in pixels the light flux reflected therefrom, i.e. it is digitized.
The coincidence of the figurative elements of the matched parts of the original and the verified documents testifies to the authenticity of document.
As documents there can be overviewed the banknotes, financial documents, different identity cards, packages and other objects representing finished products.
Besides, as documents according to the present invention are also overviewed the identification means such as excise marks, tags, labels etc., constructively joined with any product with the impossibility of separation without being disturbed the integrity of the document, and/or product, and/or lockup.
For usability of the proposed method the information about the ways of data obtaining in the database of the identification system must be accessible for the corresponding controlling services and in case of sales of the consumer goods or securities - also for the ordinary consumers.
Exemplary embodiments:
As document for verification there was used a 50€ banknote of 2002 year having the serial number X31672194518, being according to the invention an identifying sign.
As selected part for verification of authenticity of banknote there was used the last figure of the serial number, namely its part containing the figure 8.
Embodiment 1
The shop assistant who received from the purchaser said banknote and decided to verify it by the serial number of the banknote with the help of the mobile phone SHARP 902SH
(http://www.mobile-arsenal.com.ua/sharp/902/), via the Internet from the database of the identification system obtained a reference specimen. The same part on the verified banknote was read with the help of the above-mentioned mobile phone via a pocket microscope of the model
MM-100 (http^/www.radioshack.com/sm-more-product-information-for-the-illuminated- microscope-pi-2179604.html) with the value of the resolving capacity equal to 2000 pixels per inch (the file dimension constituting only 7 kilobytes) which gave the possibility to obtain the image of the relief picture thereof. Then the shop assistant transmitted via the Internet in the database of the identification system the obtained picture of the verified banknote relief according to the serial number for the automatic comparison thereof with the reference specimen. As a result of the carried out comparison it was drawn the conclusion about the authenticity of the verified banknote or the conclusion about the probability of forgery.
Embodiment 2
