Description

  The present invention relates to an identification information registration system for encrypting and registering information written in a non-contact IC chip (RFID) in order to authenticate products and the like, an inspection system for determining the authenticity of products and the like, and a portable inspection device It is.

  In recent years, counterfeits such as merchandise are increasing, and manufacturing techniques and duplication techniques are improving year by year. Even though it is a counterfeit product, it has a high degree of completeness, and it is difficult for an amateur to distinguish between a genuine product and a counterfeit product.

  In order to prevent and identify these counterfeit products, each genuine manufacturer takes measures to prevent counterfeit products, but the issue of counterfeit products is a problem that each company is undertaking. This is a problem that is difficult to see.

  Moreover, since the solution is not simple, it is not easy to solve. However, the scale of damage is now expanding much faster than expected, and each company needs to consider some sort of solution.

  Depending on counterfeit products, there is an increasing number of cases where even the person in charge of a genuine manufacturer cannot be determined without analyzing the contents. For example, a genuine product is certified by attaching a guarantee (international guarantee) to the product. Further, the authenticity of the genuine product or the counterfeit product is determined by embedding a non-contact IC chip (RFID) in the product.

  However, even when a genuine product is certified by attaching a guarantee (international guarantee) to a product, there is a problem that the guarantee (international guarantee) is often imitated.

  Furthermore, in the inspection method using a non-contact IC chip (RFID), normally the written information is registered in the management server, and it is necessary to transmit the information to the portable inspection device in advance. There is a problem that the side needs an environment that can be connected by a network or the like to receive information, and the cost increases.

  In addition, in the inspection method that does not use a network, there is a problem that accurate authentication cannot be performed as long as a contactless IC chip (RFID) can be obtained.

  Therefore, the present invention encrypts the identification information and holds it in a non-contact IC chip, so that a genuine manufacturer or a dealer can always use a non-contact IC chip only with a portable inspection device without requiring an environment such as a network. An object of the present invention is to provide a system and hardware that can inspect whether fraud has occurred based on RFID information.

  The invention according to claim 1 is means for encrypting a product-specific identification ID attached to a product or the like at the manufacturing stage and registering it in a non-contact IC chip (RFID). The registration means is performed from a portable terminal or a personal computer terminal using a dedicated writing terminal.

  The information written in the non-contact IC chip (RFID) writes information encrypted using the information written in the read-only area (ROM) as a key and non-encrypted information. In addition, although the information to be written to the non-contact IC chip (RFID) is a product-specific identification number, information such as the manufacturing date and the writing date can also be written.

  “Non-contact IC chip (RFID)” here is a general term for automatic recognition technology that reads and writes data using radio waves. Data is stored in the RFID tag, communicates with the reader by radio waves or electromagnetic waves, and the RFID tag itself generates electricity by radio waves from the antenna side, so it has a major feature that it can be used semipermanently without a battery. is there. The non-contact IC chip (RFID) used in the present invention has a read-only area (ROM) and a rewritable area (RAM).

  Furthermore, in the present invention, a non-contact IC chip (RFID) having a feature that the frequency band can be changed depending on the place where it is used (corresponding to all frequency bands) is used. By using a non-contact IC tag (RFID) compatible with all frequency bands, the convenience can be increased with one chip. For example, manufacturers and distributors can use a short wave band (13.56 MHz), and a recycler or the like can use different frequency bands depending on where it is used, such as a microwave band (2.45 GHz).

  The invention according to claim 2 is a means for reading the encrypted information written in the non-contact IC chip (RFID) according to claim 1, and is a non-contact IC by a dedicated portable inspection device. This is an inspection system having a function of reading information written on a chip (RFID) and combining encrypted information.

  “Encryption” and “decryption” here refers to exchanging data in accordance with certain rules in order to prevent information written in a non-contact IC chip (RFID) from leaking to a third party. It is. The conversion of data into decipherable data is called encryption, and the conversion of encrypted data into original data is called decryption. A bit string called a key is used for encryption / decryption, and it can be roughly divided into two types: common key encryption and public key encryption. In the present invention, common key cryptography is used.

  The invention according to claim 3 is the portable inspection apparatus and the inspection system according to claim 2, wherein basic information for authenticating in advance is read from the information stored without being stored in the portable inspection apparatus. This is an inspection system that can determine whether it is normal or abnormal.

  The invention according to claim 4 is the non-contact IC chip (RFID) according to claim 1, wherein the antenna portion is formed by sealing the non-contact IC chip (RFID) and removing the seal even once. Is a seal processing method in which the contents of the non-contact IC chip (RFID) cannot be read due to damage.

  Further, the invention according to claim 5 is the non-contact IC chip (RFID) corresponding to all frequency bands described in claim 1 and the sealed non-contact IC chip (RFID) described in claim 4.・ When recycling products, etc., even if the supplier peels off the seal, it is possible to determine the authenticity of the contactless IC chip (RFID) with the antenna part broken by using a different frequency band. Inspection system.

  The effect by this invention has the effect that the imitation of goods can be detected rapidly by encrypting the information written in the non-contact IC chip (RFID).

  In addition, since connection to a network or the like is not required, the user does not need to make extra capital investment and can introduce an inspection system at a low cost.

  Furthermore, information written in a non-contact IC chip (RFID) can be used for various purposes, but by using a non-contact IC chip (RFID) compatible with all frequency bands, a plurality of information can be obtained with one chip. Can satisfy the usage conditions of the above, and there is an effect that the cost can be reduced without an unnecessary investment.

First, FIG. 1 is a processing flow when registering product-specific identification information for identifying a product according to the present invention in a non-contact IC chip (RFID). Information for identifying the product is registered in the non-contact IC chip (RFID) 40 shown in FIG. 4 for the product decided to be shipped or the product passed the inspection at the manufacturing factory. Information registration 10 indicates a process of writing product-specific identification information in a non-contact IC chip (RFID) 40. An unused non-contact IC chip (RFID) 40 is set in a dedicated non-contact IC chip (RFID) read writer connected to a computer terminal or the like. In this case, it is desirable that the computer and the dedicated non-contact IC chip (RFID) read writer are connected by USB or RS-232C, but the connection method is not limited as long as data can be written.

  After the unused contactless IC chip (RFID) 40 is set in a dedicated writing device, information registration 10 is performed on a computer terminal or the like to which the dedicated writing device is connected. Information to be registered includes information such as a product-specific identification number. Since the information registered in the non-contact IC chip (RFID) 40 needs to be unique (the same thing does not exist), information other than product-specific identification information may be added to make the information unique. Is possible.

  When information to be registered in the unused contactless IC chip (RFID) 40 is input, encryption processing is performed based on the input information. The encryption 11 performs encryption using the information written in the read-only area (ROM) as a key. After the data encryption is completed, the encrypted data and the non-encrypted information are written to the non-contact IC chip (RFID) 40.

  The produced non-contact IC chip (RFID) 40 is sealed and can be attached to a product. The position of application to the product is not limited and can be applied to any location. Moreover, it may be used by being embedded in a guarantee (international guarantee) card. When the non-contact IC chip (RFID) 40 is sealed even once, the antenna portion 41 is damaged and cannot be read.

  Next, FIG. 2 is a processing flow showing the processing of the inspection system 20 by reading the information in the non-contact IC chip (RFID) 40 by the portable inspection device 50 shown in FIG. A person in charge of sales, a person in charge of sales, etc. can inspect the authenticity of the product delivered to the store using the portable inspection device 50 and the inspection system 20. The portable inspection device 50 that performs the inspection can perform the inspection only with the inspection system 20 that is installed in advance, and does not need to download information such as a product necessary for reading in advance. In the inspection method, when the portable inspection device 50 is brought close to the non-contact IC chip (RFID) 40, the information in the non-contact IC chip (RFID) 40 is analyzed by an internal program to inform the user whether it is a genuine product or a counterfeit product.

  In the inspection system, data is read when the portable inspection device 50 is brought close to the target non-contact IC chip (RFID) 40. Here, when the information of the non-contact IC chip (RFID) 40 cannot be read, the inspection system 20 determines that it is abnormal and performs error processing. The frequency band used here is assumed to be read in the short wave band, but the frequency band may be changed according to the use situation.

  Next, the read data is combined. The data decryption 21 performs decryption on the information of the encryption part written in the RAM part of the non-contact IC chip (RFID) 40 with a portable terminal or the like using the ROM information as a key. If the result of collation with the decrypted information and the information in the non-encrypted part is found to be invalid, the inspection system 20 determines that the data is abnormal and performs error processing. If there is no problem, the screen 51 displays that the portable inspection apparatus 50 has no problem.

  When the portable inspection apparatus performs the inspection, it is not necessary to store information on the product to be inspected in the portable inspection apparatus 50 in advance, and the inspection system 20 including the composite 21 can determine whether the inspection is normal or abnormal. it can. The user can determine the authenticity at any time with the portable inspection device 50 including the inspection system 20.

  The condition for determining that the inspection system is abnormal is when the information of the non-contact IC chip (RFID) 40 cannot be read, or when the read data is determined to be abnormal by combining the read data. This is probably because the IC chip (RFID) 40 is defective or forcibly peeled off and damaged. In addition, when it is determined that the result of reading is abnormal, it is considered that the possibility of being forged is high.

  The inspection system can be performed at any time. For example, an inspection can be performed at the time of delivery of a product to a store, before opening or after closing, and whether or not fraud is performed on the product. Since the inspection only involves holding the portable inspection device 50 over the non-contact IC chip (RFID) 40, the inspection can be performed earlier than the visual confirmation.

  Furthermore, since the non-contact IC chip (RFID) 40 has the feature of being compatible with all frequency bands, the manufacturing system and the shop use the inspection system 20 in the short wave band, and the recycling center that collects products uses the microwave band. The authenticity of the product can be determined. Normally, the non-contact IC chip (RFID) 40 that has been made into a seal cannot be read by a normal inspection apparatus because the antenna portion 41 is broken when the seal is removed even once, but it is a portable type using a microwave band. Information can be read by using the inspection device 50.

  Next, FIG. 3 is a diagram showing the inside of a non-contact IC chip (RFID). The non-contact IC chip (RFID) 30 has a read-only area (ROM) and an area where information can be read and written (RAM). Basically, the readable / writable area (RAM) can be used any number of times, but the RAM area used in the present invention is used as an area (One-Time-RAM) that cannot be rewritten once information is written. To do.
