Description

The technical field to which the utility model belongs.

The invention relates to devices for reading and recognizing object data, and more particularly, to devices for verifying the authenticity of documents, banknotes, valuable items having randomly distributed identification elements, and having a graphic image with identification information printed on the object being checked or accompanied by it certificate including a scanner of the above graphic image connected to a decryptor of identification information contained in the graphic com image, a sensor of randomly distributed identification elements, while the sensor and decoder are connected to a module for comparing identification information received from the decoder and from the sensor of randomly distributed identification elements, and is electrically connected to the authenticity indicator of the object being checked and can be used to verify the authenticity of valuable documents of value papers, banknotes, expensive goods, such as jewelry.

The following terms are used below.

An asymmetric key or cipher is the same as a cryptographic system with a public key, as well as a system with ciphers based on public keys. Asymmetric, they are called here because instead of one key used for both encryption and decryption, they have two. One can be encrypted and the other decrypted - it is impossible to carry out two actions with the same key.

The level of technology.

Currently, the protection of documents, banknotes, securities and valuable items are acute. There are many devices for authentication and authentication. But existing devices today have several disadvantages.

It is known a device for verifying the authenticity of documents, banknotes, valuable items that have randomly distributed identification elements and have a graphic image with identification information printed on the object being checked or its certificate, including a scanner of the above graphic image connected to a decoder identification information contained in a graphic image, a sensor randomly distributed identification elements, while the sensor a descrambler coupled to the comparison module identification information received from the decoder and from the sensor of randomly distributed identification elements, refer to the description EP 2485178 A1, D21N 15/06.; G06K 9/00, 08/08/2012

Its disadvantage is the limited ability to determine the authenticity. Indeed, if the identification information corresponding to randomly distributed identification elements and printed on the object, which can be checked by the graphic image scanner and compared with the graphic image printed on the checked object or its accompanying certificate, is additionally encoded, then the device simply will not work, since will not be able to recognize additional code. Moreover, it is additional coding that makes it impossible to fake an outsider who is aware of the principles of protecting the authenticity of the object.

The prior art also knows a device for verifying the authenticity of documents, banknotes, valuable items having randomly distributed identification elements and having a graphic image with identification information printed on the object being checked or its accompanying certificate, including a scanner of the above graphic image, connected to a decryptor of identification information contained in a graphic image, a sensor of randomly distributed identification elements s, wherein the sensor and decoder coupled to the comparison module identification information received from the decoder and from the sensor of randomly distributed identification elements, and electrically coupled with an indicator authentication inspected object, see the patent description US 2007170265 A1, B42D 15/00.; G06K 19/06; G07D 7/12; G07D 7/20, July 26, 2007.

This system is the closest in technical essence and the achieved technical result to the proposed solution and is taken as a prototype of the proposed utility model.

Its disadvantage is the limited ability to determine the authenticity. Indeed, if the identification information corresponding to randomly distributed identification elements and printed on the object, which can be checked by the graphic image scanner and compared with the graphic image printed on the checked object or its accompanying certificate, is additionally encoded, then the device simply will not work, since will not be able to recognize additional code. Moreover, it is additional coding that makes it impossible to fake an outsider who is aware of the principles of protecting the authenticity of the object.

Disclosure of a utility model.

The present utility model, based on this original observation, mainly aims to offer a device for verifying the authenticity of documents, banknotes, valuable items that have randomly distributed identification elements and have a graphic image with identification information printed on the object being checked or its certificate accompanied , allowing at least to smooth out the above drawback, namely to provide the ability to determine the authenticity of documents, monetary What are the, valuable articles, having randomly distributed identification elements, when the data about these elements not only are in the form of graphic images to the identification information adapted for reading scanner, but additionally encoded.

To achieve this goal, the authentication device further comprises a decoding module associated with a decoder and a comparison module, and said graphic image includes key-encoded identification information of a random distribution of said identification elements.

Due to such an advantageous characteristic, it becomes possible to decode the identification information obtained from the graphic image and to ensure the operation of the device in cases where such information is encoded.

There is a variant of the utility model in which the decoding module is adapted for decoding based on an asymmetric key.

Due to this advantageous characteristic, it becomes possible to use two keys, one of which is known only to the encoder, and the second is provided to the user of the authentication device. Moreover, a user who has a second key can exclusively verify the authenticity of objects, that is, decode graphic information, but in no case encode it himself. Thus, the prerogative of coding, for example, in the case when the object is banknotes, always remains with the issuer of banknotes, for example, with the Central Bank.

The set of essential features of the proposed utility model is unknown from the prior art for devices of similar purpose, which allows us to conclude that the criterion of "novelty" for the utility model is met.

- RSA, (a method based on the computational complexity of the factorization of large integers),

- Diffie-Hellman, a method based on the computational complexity of taking logarithms in finite fields

Implementation of a utility model.

Devices for verifying the authenticity of documents, banknotes, valuable items that have randomly distributed identification elements and have a graphic image with identification information printed on the object being checked or its certificate accompanied by the following method. (See FIG. 2).

As randomly distributed identification elements of the object being checked, certain parameters are selected that are inherent in the object itself, the material from which it is made. The device’s sensor is adapted to read just such parameters and turn it into a sequence of numbers. Further, this sequence of digits can be encoded using an asymmetric key. Already this new coded sequence of numbers and letters is converted into a graphic image and applied directly to the object itself or to the certificate that is attached to it, for example, if the museum value is used as an object. As a graphic image, a barcode or a QR code can be selected.

The proposed device can now easily verify the authenticity of such an object that has randomly distributed identification elements and has a graphic image with identification information printed on the object itself or on its certificate in the form of a bar code or QR code.

Enough for this:

- Stage A1. Scanner consider the above barcode or QR code,

- Stage A2. Recognizer identifier contained in this graphic image to recognize it;

- Stage A3. Decrypt the decoding module, and for this, the public key of asymmetric encoding is used.

- Stage A4. The sensor of randomly distributed identification elements, consider the location of randomly distributed identification elements on the object.

- Stage A5. Convert the information obtained in step A4 into a sequence of digits ..

- Stage A6. The comparison module correlates the numerical sequence corresponding to the identification information received from the sensor randomly distributed identification elements, and from the decoder.

- Stage A7. If the numerical sequences match, verify the authenticity of the object, the device indicator lights up, for example, a green light, if the numerical sequences do not match, detect the fake object, the device indicator lights up in another mode, for example, a red light.

The sequence of steps is approximate and allows you to rearrange, add or perform some operations at the same time without losing the ability to verify the authenticity of the object. Modifications of the method include - other authentication indication indications, various methods for selecting identification elements, various asymmetric encoding methods.

As well as various options for applying graphic elements, for example, a completely graphic element can be replaced with a broader concept - an element that carries an information component. An example is NFC technology (“near field communication” - short-range wireless high-frequency communication technology that enables the exchange of data between devices located at a distance of about 10 centimeters) and RFID (a method for automatically identifying objects in which data is read or written using radio signals stored in the so-called transponders).

Also, the encoding process can be attributed to modifications, since the data themselves can be encoded with an asymmetric key directly or indirectly, for example, encoding a hash and / or checksum (say SHA256) of the data. In the second case, it is an electronic signature method.

Examples of the use of the proposed technical solution.

Example 1. Verification of banknotes.

As randomly distributed identification elements of banknotes, the coordinates of colored hairs interspersed in banknote paper can be used. For example, a sequence of coordinates of the ends of these colored hairs can be taken. With arbitrarily selected and assigned to the paper banknote coordinate system.

Further, this sequence of digits can be encoded using an asymmetric key. Already this new coded sequence of numbers and letters is converted into a graphic image and applied directly to the banknote. As a graphic image, a barcode or a QR code can be selected.

The proposed device can now easily verify the authenticity of such banknotes having randomly distributed identification elements, namely, in this example, colored hairs, and having a graphic image with identification information printed on a banknote in the form of a bar code or QR code.

- if the numerical sequences coincide, ascertain the authenticity of the banknote, the device indicator lights up, for example, a green light; if the numerical sequences do not match, counterfeit a banknote, the device indicator in another mode lights up, for example, a red light.

Example 2. Authentication of paintings.

As randomly distributed identification elements of the picture can be used levels or intensities of the glow of the paint in x-ray radiation. As a sensor, a device is used, which is a flatbed scanner, combined with an x-ray source. Since under the influence of x-ray radiation on the surface of the paint the electrons from the beam pass from one energy level to another, the paint begins to glow, and it shines differently, gives different spectra and intensity.

- The specified sensor takes data;

Example 3. Validation of valuable goods or museum relics.

Defects of their material are used as randomly distributed identification elements of valuable goods or museum relics, for example, a collection knife, precious weapons.

The sensor is then a flaw detector, which is adapted for, for example, ultrasonic flaw detection. In this example, everything else is similar to example 2.

The proposed device for verifying the authenticity of documents, banknotes, valuable items having randomly distributed identification elements has a clear purpose, can be implemented by a specialist in practice and, when implemented, ensures the implementation of the declared purpose. The possibility of being implemented by a specialist in practice follows from the fact that for each feature included in the formula of a utility model based on the description, a material equivalent is known, which allows us to conclude that the criterion of "industrial applicability" for the utility model is met.
