Abstract

The present invention relates to an RFID-based genuine product certification service system using a cipher update algorithm for forgery prevention and a method thereof. According to the present invention, in using a radio electronic tag (RFID tag) to prevent fake drugs, food and beverages, luxury goods, and alcoholic beverages and the forgery of important documents, such as, an identification card, written contract, and notarial document, a genuine product certification server stores an RFID access cipher and a variable genuine product certification cipher in an RFID tag through a wired/wireless terminal having an RFID writer/reader while simultaneously storing the RFID access cipher and the variable genuine product certification cipher in a database of the genuine product certification server. The genuine product certification server determines whether a product is genuine or not by using the tag information and the genuine product certification cipher stored in the RFID tag. The genuine product certification server also frequently changes the genuine product certification cipher in the RFID tag by using the wired/wireless terminal having the RFID writer/reader in response to an attempt of the genuine product certification or at regular intervals. Accordingly, the RFID-based genuine product certification service system of the present invention can prevent the genuine product certification of a replica by using the variable genuine product certification cipher updated periodically even if the RFID is copied for the forgery of another person.

1 is a block diagram of a conventional 13.56 MHz RFID tag, an RFID reader, and a system.

An RFID (radio frequency electronic tag) reads an RFID tag 10 including information inherent to the product and tag information attached to the product using a radio communication technology of 13.56 MHz or 900 MHz RFID frequency band Is a system for transmitting information recognized by the RFID reader 20 and the RFID reader 20 to an application of the host computer 30 through the RFID middleware.

The RFID technology for product management is standardized in ISO / IEC JTC1 SC31, and the air interface protocol for each frequency between RFID reader and tag is defined in ISO / IEC 18000 series.

RFID frequencies are 135kHz, 13.56MHz, 433MHz, 860-960MHz. 2.45 GHz band is used. The low-frequency 13.56MHz RFID system is used to recognize the tag attached to the product, and the recognition distance is only a few centimeters. The high-frequency 900MHz UHF RFID system proposed by EPC Global can recognize up to 100m and can be used for distribution, .

The NFC Forum's mobile RFID convergence provides mobile RFID information services using mobile phones in the 13.56MHz RFID frequency band and links them to the logistics distribution areas (B2B and B2C) of the UHF 900MHz RFID frequency band of EPC Global, Convergence is presented.

FIG. 2 is a diagram showing an RFID frequency standard of UHF 900 MHz band in each major country.

The UHF band RFID frequency used by major countries is 902-928MHz ISM (Industrial, Scientific, and Medical) band, RFID frequency band is 500kHz occupied bandwidth of one channel and more than 50 channels are used in Europe. 865-868MHz is used as the RFID frequency band, and the occupied bandwidth of one channel is limited to 200kHz and only 15 channels are used. Australia has a bandwidth of 918-926MHz, Korea has a bandwidth of 200kHz similar to 910-914MHz Europe, and Japan uses 950-956MHz.

Table 1 compares the functions of RFID tags and readers using 13.56 MHz and 900 MHz frequencies.

RFID          13.56 MHz            900 MHz leader Within 10cm distance Long distance recognition (~ 1m) tag - inventory management, parking management, library book management
- Transportation card, financial card, smart card, ID card
- Mobile RFID information service using smartphone - RFID tags on B2C distribution and logistics B2B products

The RFID reader and the RFID tag are composed of a forward link and a reverse link according to the transmission direction of information. The forward link transmits a command signal and a continuous wave (CW) signal that supplies power to the tag to obtain unique information of the tag from the RFID reader to the tag. The reverse link is a process until the tag reaches the tag signal through the back scattering process based on the CW signal received from the RFID reader.

An RFID tag is composed of a tag chip and an antenna including unique product information, and is classified into an active tag and a passive tag according to a power supply scheme.

The active tag uses internal battery power and can collect information independently of the RFID reader. It has a disadvantage of increasing the size, the weight, and the cost of the built-in battery. Therefore, when the battery reaches the end of its useful life, the function of the RFID tag is lost.

A passive tag generates DC power from RF signals received from the RFID reader to drive the tag chip. The communication between the passive tag and the RFID reader proceeds asynchronously. When there is a response request from the RFID reader, the passive tag transmits the data through the back scattering modulation. The passive tag does not have a separate power source but receives the driving power of the RFID tag by the electric power received from the RFID reader, and the distance to receive power from the RFID reader is limited, so that the recognition distance is short and the electric power is driven at low power.

Systems equipped with RFID tags and readers are being applied in many fields such as inventory management, distribution, logistics, port, pharmaceutical industry, medical industry, and defense ammunition management.

An RFID system for encrypting an electronic commodity code comprises: an RFID tag for storing an electronic commodity code (EPC), for transmitting the stored electronic commodity code to the RFID reader, for receiving and storing the encrypted electronic commodity code from the RFID reader; An RFID reader that reads an electronic commodity code stored in the RFID tag and transmits the electronic commodity code to the middleware, and transmits an encrypted electronic commodity code transmitted from the middleware to the RFID tag; Encrypts the electronic commodity code (EPC) in which the random number is padded based on an encryption algorithm after padding a random number to the electronic commodity code transmitted from the RFID interrogator, and transmits the encrypted electronic commodity code to the front end code and the rear end code A middleware having an encryption module for storing the encrypted electronic product code in a database and transmitting the encrypted electronic product code to the RFID tag via the RFID reader; And a database having an index area and an information area in which a front end code and a rear end code of the electronic commodity code encrypted by the encryption module of the middleware are stored, respectively.

However, the RFID tag can read the tag value and the password stored in the RFID tag of the wired / wireless terminal equipped with the RFID reader. However, there is no way to solve the RFID tag when the RFID tag is forged or modified.
