Description

The utility model relates to means intended to counter unauthorized production and / or use of objects, in particular, unauthorized production of goods.

A known system for marking and authenticating objects containing an encryption device, a verification device and an electronic tag configured to generate and transmit encoded sealing information for reading by portable and / or stationary readers, comprising a microwave unit connected to the output of a pulse code converter with an autonomous source power supply (RU 2248292 C1).

There are also known systems for marking and authenticating objects containing an encryption device, a verification device and an electronic tag made in the form of a radio frequency identification device (RU 2359324 C2, RU 2417939 C2, RU 2395402 C1, RU 2420621 C2).

The disadvantage of these known systems is the low degree of authentication of objects.

There are also known systems for marking and verifying the authenticity of objects containing an encryption device including means for generating an electronic digital signature, a bar code including an electronic digital signature, and a verification device including means for verifying an electronic digital signature (RU 2132569 C1, RU 2207624 C1 )

The disadvantage of these known systems is the inability to remotely verify the authenticity of the object, as well as the need to verify the authenticity of the object of access to the central database.

Closest to the proposed utility model is a known system for marking and authenticating an object, comprising an encryption device including means for generating an electronic digital signature, an electronic tag including encoded information about the object and an electronic digital signature generated by the encryption device based on the unique identifier of the label and a private key, and a verification device, including means for verifying an electronic digital signature using a public key (RU 2281552 C2 - prot type).

In the prototype system, the electronic tag is made in the form of a microchip consisting of a memory block and a contact connector connected with it, which is designed to enable data to be input or output when reading information from the memory block using a verification device.

The disadvantage of the prototype system is the need for direct contact between the electronic tag and the verification device.

The technical task is to create a system for marking and authenticating an object that is devoid of this drawback.

The technical result of the proposed utility model is the ability to remotely verify the authenticity of the object.

The specified technical result is achieved by the fact that in the marking and authentication system of the object containing the encryption device, including means for generating an electronic digital signature, an electronic tag including encoded information about the object and an electronic digital signature generated by the encryption device based on the unique identifier of the label and a secret key, and a verification device, including means for verifying an electronic digital signature using a public key, an electronic tag is made and in the form of a radio frequency identification device formed by a microchip and an antenna connected to its terminals.

The radio frequency identification device contains an integrated microcircuit (microchip), including an unchangeable memory area with a recorded unique identifier for the label, as well as a rewritable memory area used to store an electronic digital signature, public key and encoded information about the object. It should be clarified that the public key can be stored on any other open medium outside the microchip. The antenna of the RFID device is electrically connected to the microchip and is used for contactless data exchange between the electronic tag, the verification device and the encryption device.

The RFID device can be made in the form of any RFID tag (http://www.xakep.ru/post/28394/default.asp, 2005). Widespread passive RFID tags are small in size, have an almost unlimited service life and do not need to be replaced by batteries, however, in general, they have a shorter reading range, depending on the energy of the electromagnetic signal distributed by the verification device.

It is possible to use a semi-passive (semi-active) RFID tag, which is similar to a passive tag, but is equipped with a battery that provides microchip power supply. Moreover, the range of these labels depends only on the sensitivity of the reader receiver, and they can function at a greater distance and with better characteristics. Active RFID tags are also widely known and are larger than passive tags. However, if the dimensions of the marked object allow, the RFID device can be made in the form of an active RFID tag with its own power source. Active RFID tags, in comparison with passive ones, have a significantly longer reading range (up to 300 m), as well as the ability to identify information at a high speed electronic tag relative to the verification device.

The radio frequency identification device, preferably, can be made in the form of a UHF RFID tag widely used in Russia, operating in the range of 863-868 MHz. The radio frequency identification device preferably has a user memory for storing an electronic digital signature of at least 512 bits and a unique identifier of at least 128 bits.

The use in the proposed system of an electronic tag made in the form of a radio frequency identification device formed by a microchip and an antenna connected to its terminals allows verification of the authenticity of the object not only in the absence of direct contact between the electronic tag and the verification device, but also in the absence of direct visibility of the marked object .

In addition, RFID devices have such properties as compactness, high speed of recording and receiving data, consistently high quality of work in difficult climatic conditions and aggressive environments, resistance to pollution, which additionally ensures reliability and high efficiency of the entire system.

As the encryption device can be used any suitable device, for example. Speedway Revolution R420 (http://www.cisper.n1/rfd/down1oads/Tmpinj_Speedway_Revoution_Presentation.pdf. 2009). The encryption device is equipped with a stationary high-performance RFID reader, which, in accordance with GOST R 34.10-2001 (date of introduction 01.07.2002), has a private key and means for generating an electronic digital signature and public key.

The verification device comprises a mobile RFID reader equipped with a program for decrypting an electronic digital signature using a public key. Any suitable device (http://montel-rek.com/a21591-schityvatel-beskontaktnyh-kart.html. 2010), for example, a Nordic ID mobile terminal running Windows CE, can be used as a verification device.

The operation of the system is as follows.

Encryption is the exclusive competence of the authorized body (state body), for example, regulating the circulation of goods of this type: alcohol, drugs, jewelry, etc. The encryption device reads the unique identifier of the tag stored in the corresponding memory area of the electronic tag, then, using the private key stored in the authorized body, generates an electronic digital signature with the public key and writes the received digital signature and public key to the corresponding memory area of the electronic tag .

Verification can be carried out by any interested person having a verification device, made, for example, in the form of a mobile terminal. The tester sends a verification device towards the marked object that reads the corresponding memory areas of the electronic tag. Next, the verification device launches an authentication program for digital signature in accordance with GOST R 34.10-2001. The result of the verification is the authentication of this electronic tag, i.e. confirmation of the fact that the digital signature was recorded by the encryption device of the authorized body. The answer is in binary form YES or NO and appears on the screen of the verification device.
