Description

A system for certificating honest goods based on NFC tag and a method thereof

The present invention relates to an NFC tag-based activation system and a method thereof, and more specifically, in generating an NFC tag, not only the product's unique identification code (UID), but also an additional second code (eg, UUID) It is an invention related to an NFC tag-based activation system and method for preventing illegal copying of an NFC tag by generating, and thus ensuring a consumer's use of a genuine tag.

As the prevalence of color copiers or color scanners has recently expanded and 3D printers and scanners have been developed, the amount of counterfeit products that illegally duplicate product identification information such as trademarks, marks, logos, and holograms and attach them to products to distribute them is increasing. have. Accordingly, the value and reliability of the genuine brand among consumers decreases, and it is also a major cause of deteriorating consumers' desire to purchase.

In order to solve this problem, research on product activation methods to prevent product defects caused by counterfeit products and to protect their intellectual property rights has been actively conducted. For example, in the related art, the identification number information in the product is read and compared with pre-stored valid identification number information to determine the products as genuine, and if they do not match, the products are determined as fixtures or counterfeits. The method is basically used.

For this, it is necessary to register a valid identification number for the product in advance. When the product's identification number information is provided in the form of an electronic tag, tag encoding to insert identification number information and product information in the corresponding electronic tag The process is essential. However, in the case of mass production, it is possible to easily insert information by performing tag encoding at the production process step. However, if it is produced in small quantities or provided in the form of a card rather than in the form of an electronic tag, the encoding of the electronic tag is not supported, so the seller separately There is the inconvenience of inserting into an electronic tag.

1 is a schematic diagram for explaining a conventional NFC tag-based genuine identification method. For reference, NFC (Near Field Communication) is one of radio tag (RFID) technologies and corresponds to a contactless communication technology using a frequency band of 13.56 MHz. Because the communication distance is relatively short, it has excellent security and low cost, which corresponds to the next-generation short-range communication technology that is attracting attention. Both data read and write are possible, and there is an advantage of not having to set communication between devices such as Bluetooth.

As illustrated in FIG. 1, an NFC tag 2 for product activation is attached to the product 1, wherein the ID information of the NFC tag 2, that is, UID and PID (Product ID) is attached to the server 4. It is registered at the same time. After tagging the NFC tag 2 attached to the product 1 through the consumer terminal 3, the consumer reads the UID and PID, and then reads the PID and PID read by the UID and PID registered in the server 4 Compare with.

As a result of comparison, if (i) the UID and PID tagged by the consumer terminal 3 and the UID and PID registered in the server 4 match, the corresponding tag is determined to be genuine, but (ii) the consumer terminal 3 If the tagged UID and PID and the UID and PID registered in the server 4 do not match, it is determined that the corresponding tag is not a genuine product but a fake or counterfeit product.

In the conventional typical NFC tag-based activation method, the UID of the NFC tag is used as it is when the chip is produced, and the UID is written to the NFC tag through the NFC reader along with the PID. However, as the UID is utilized by using the information given at the time of chip production, there is always a risk that the tag UID information can be duplicated or leaked before use regardless of the user's will.

Therefore, a new type of activation method capable of fundamentally blocking the use of a non-genuine tag while compensating for the disadvantages of the conventional NFC tag-based activation method, and the user demand and need for the device and system are gradually increasing in the art.

For reference, the elements 10, 20, 30, and 40 shown in FIG. 2 correspond to exemplary elements for describing the operation, function, etc. of the NFC tag-based activation system 100, and thus additional elements It will be apparent that more can be provided.

For example, the tag generation terminal 10, the manufacturer terminal 20, and the consumer terminal 40 may each be equipped with an NFC function, and read or write information through NFC tagging. ) Can be implemented as a possible terminal. For reference, the tag generation terminal 10, the manufacturer terminal 20, and the consumer terminal 40 may each be implemented as a user terminal, where the user terminal is a subscriber unit, a subscriber station, a mobile station, a mobile, It may also be referred to as a remote station, remote terminal, mobile device, access terminal, terminal, wireless communication device, user agent, user device or user equipment (UE). The access terminal is connected to a cellular telephone, cordless telephone, session initiation protocol (SIP) telephone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless connectivity, computing device or wireless modem. It may be another processing device.

In addition, each of the tag generation terminal 10, the manufacturer terminal 20, the activation server 30, and the consumer terminal 40 includes communication units 13, 24, 32, 41 for wired/wireless communication with other elements. May be provided, the communication unit (13, 24, 32, 41) is provided for direct connection to the outside or through a network, and may be a wired and/or wireless communication unit communication unit (13, 24, 32, 41) have. Specifically, the communication unit communication unit (13, 24, 32, 41) may transmit data from the control unit, the storage unit or the like wired or wirelessly, or receive data from the outside by wired or wireless transmission to the control unit or stored in the storage unit. . The data may include content such as text, images, and moving images, and user images. As a communication method implemented in the communication units 13, 24, 32, and 41, NFC (Near Field Communication) is exemplarily described in the following specification, but this is an example and the technology according to an embodiment to which the present invention is applied Various wired and wireless communication technologies applicable in the field may be used.

For reference, an NFC tag-based activation method according to an embodiment of the present invention includes (i) a process of generating a security-reinforced tag performed in the tag generation terminal 10, and (ii) a manufacturer. It can be largely classified into a process of registering a genuine product performed in the terminal 20 and (iii) a process of genuine product activation performed in the consumer terminal 40, which are illustrated in FIGS. 3, 4, and 5, respectively. Is shown as an enemy.

The tag generation terminal 10 reads the UID from the first tag through the NFC reader 12 and generates a UUID from the read UID using a unique user ID (UUID) generation process, and the generated UUID is A second tag can be generated by writing to one tag. Here, as shown in FIG. 2, the tag generation terminal 10 according to an embodiment of the present invention may include a UUID generation unit 11 configured to execute a UUID generation process.

For reference, the term “UUID” is used in the following specification, which is an additional identification code distinguished from “UID (Unique Identification Code)” used in the NFC tag, and the present inventor to prevent illegal copying of the NFC tag. It corresponds to the ID information of the newly proposed NFC tag. As described above, the NFC tag-based activation method according to an embodiment of the present invention can be implemented as an ID that cannot be duplicated by using a UID in generating a UUID and thus enhancing double security.

In addition, in the following specification, the tag in which the UID is recorded is referred to as a'first tag', and by the tag generating terminal 10, more precisely, the UUID generating unit 11 of the tag generating terminal 10 A tag whose UUID is additionally written by is referred to as a'second tag' (that is, both the UID and the UUID are written in the second tag), and the UUID designed to prevent security enhancement/replication. The added second tag may be used for genuine registration at the manufacturer terminal 20 and activation at the consumer terminal 40.

In this regard, in the second tag to which the UUID is added is generated by the tag generating terminal 10, the UID may be written in the UID memory area of the second tag and the UUID may be written in the data memory area of the second tag. (For example, see the conceptual diagram shown on the left side of FIG. 2). Accordingly, the UID defined according to the NFC standard specification is written to the UID memory area unique to the NFC tag, and the UUID proposed by the present inventors is written to a separate data memory area distinct from the UID memory area unique to the NFC tag, In addition to preventing misrecognition of UIDs and UUIDs, it is possible to clearly recognize and recognize two IDs, UID and UUID, at a later NFC tagging.

In addition, the UUID generation unit 11 of the tag generation terminal 10 according to an embodiment of the present invention is implemented to execute a predetermined UUID generation process, where the logic of the UUID generation process can be leaked or exposed to the outside. Possibilities may exist. In order to prevent such leakage or exposure in advance, according to a further embodiment of the present invention, the UUID generation unit 11 may be configured to generate different UUIDs by executing a different UUID generation process for each product or for each manufacturer. Accordingly, it is possible to fundamentally block the possibility of leakage and duplication of UUID generation logic that may occur by executing the same UUID generation process regardless of the product and/or manufacturer.

In addition, a second NFC-based tag with UUID added is generated by the tag generating terminal 10, and these tags are generally provided in the form of stickers to be attached to each product or inserted into a stopper or an external case. It may be formed integrally with. Alternatively, the tag may be provided in the form of a card to be given to the product.

For reference, the second tag may further include a manufacturer name, a manufacturing date, a manufacturing number, authentication numbers for authenticity certification, a security key, etc., and these tags may be made of aluminum, synthetic resin, paper, or the like.

The process of generating the second tag by the tag generating terminal 10 as described above is more specifically illustrated in FIG. 3. More specifically, FIG. 3A is a schematic flowchart for describing tag generation (S300) in the tag generation terminal 10, and FIG. 3B is a specific flowchart of the UUID generation process (S330).

Referring to FIG. 2 and FIG. 3A together, generation of a security-enhanced tag (S300) according to an embodiment of the present invention is performed in the tag generation terminal 10, and a series of steps are exemplarily illustrated in FIG. 3A. do.

First, when the first tag, that is, the tag including the UID as the ID information is input (S310), the NFC reader 12 of the tag generation terminal 10 can read the UID by tagging the first tag (S320). When the UID of the first tag is read, the UUID generation unit 11 of the tag generation terminal 10 may generate a UUID using the UUID execution process stored therein (S330) (S340). For reference, more specific logic for the UUID generation process will be described in detail in FIG. 3B below.

When the UUID is generated from the UID by the UUID generating unit 11, the generated UUID is written to the first tag through the NFC reader 12 (S350), and finally the UUID is added to the second tag, that is, the UID. The generated second tag may be generated (S360). Here, in writing the UID and the UUID to the second tag, as described above, while the UID is written to the UID memory area of the second tag, the UUID is written to the data memory area of the second tag.

Further, the UUID generation unit 11 may be configured to generate different UUIDs by executing different UUID processes for each product or for each manufacturer, and thus may occur by executing the same UUID generation process regardless of the product and/or manufacturer. It is possible to fundamentally block the possibility of leakage and duplication of UUID generation logic.

For example, for easy understanding of the present invention, assuming that the UID of the first tag is “12345”, this UID information is used as it is when the tag chip is produced. There is a possibility of spillage. Accordingly, according to an embodiment of the present invention, the UUID generation unit 11 utilizes a predetermined UUID generation process (for example, adding a cryptographic code “1” to the UID), and the UUID from the UID is the second UID (this In the case, it is possible to fundamentally block the use of non-genuine tags by generating UID(12345) + password code(1) = “12346”), and the UUID generation process that adds password code “1” to the UID is specific product or specific It can be applied only to the manufacturer.

3B shows an example of an exemplary UUID generation process (S330) for generating UUIDs from UIDs. 2 and 3B, the UUID generation process S330 may be performed by the UUID generation unit 11 of the tag generation terminal 10. For reference, the UUID generation unit that implements the UUID generation process may be provided through a predetermined supply contract from the supplier of the tag generation terminal 10 to the manufacturer of the manufacturer terminal 20, and accordingly also to the manufacturer terminal 20 By providing the same UUID generation unit 21, it is possible to implement genuine registration based on the NFC tag, which will be described in more detail in FIG. 4 below.

The UUID generation process S330 implemented by the UUID generation unit 11 is characterized by generating a new ID, i.e., a UUID based on the UID, and an exemplary generation procedure for this is shown in FIG. 3B. First, the UUID generation unit 11 may divide the UID read from the first tag (that is, the tag having only the UID) into a plurality of partial UIDs (S331). For example, the UID of the NFC chip may have a length of 7 bytes (56 bits), and S331 corresponds to a step of dividing the 7 bytes (56 bits) UID into a plurality of partial UIDs having a predetermined length. .

When the read UID is divided into a plurality of partial UIDs (S331), the UUID generation unit 11 may perform sum and multiplication operations with a predetermined first constant for each of the divided plurality of partial UIDs (S332). . Thereafter, the UUID generation unit 11 may extract at least one partial UID having a length of N bits or more from among the plurality of calculated partial UIDs (S333), where N is a natural number of 2 or more.

When at least one partial UID having a length of N bits or more is extracted (S333), the UUID generating unit 11 may output the M least significant bits (LSB) from the extracted at least one partial UID (S334), Here, M is a natural number of 2 or more, and N≥M. When M least significant bits (LSBs) are output from the extracted at least one partial UID (S334), the UUID generation unit 11 may generate UUIDs by interconnecting the output M LSBs (S335).

In this regard, the UUID generation unit 11 according to an embodiment of the present invention is characterized in that it generates different UUIDs by executing different UUID generation processes for each product or manufacturer, and thus the UUID generation process shown in FIG. 3B. (S330) is only an example of various processes for generating a UUID.

4 is a schematic flow chart for explaining the genuine registration (S400) in the manufacturer terminal 20. As described with reference to FIGS. 3A and 3B, when the second tag with the UUID added is generated by the tag generating terminal 10, the second tag thus generated and the UUID supplied from the manufacturer of the tag generating terminal 10 Genuine registration may be performed at the manufacturer terminal 20 by utilizing the generation unit 21.

More specifically, as shown in FIG. 2, the manufacturer terminal 20 according to an embodiment of the present invention includes a UUID generation unit 21, an NFC reader 22, a control unit 23, and a communication unit 24 ). For reference, elements 21, 22, 23, and 24 of the manufacturer terminal 20 shown in FIG. 2 correspond to exemplary elements for describing functions, operations, and the like of the manufacturer terminal 20, and thus additional It will be apparent that the element may be further provided in the manufacturer terminal 20.

Referring to Figures 2 and 4 together, the genuine registration (S400) in the manufacturer terminal 20 is described. When the second tag (that is, the UUID-added tag) generated by the tag generating terminal 10 is input (S410), the manufacturer terminal 20 utilizes the NFC reader 22 to read the UUID from the second tag. Then (S420) and can read the UID (S430). As already described, since the second tag generated by writing the UID to the UID memory area and writing the UUID to the data memory area by the tag generation terminal 10 is provided to the manufacturer terminal 20, the manufacturer terminal 20 ) It is possible to read both the UID and the UUID from the second tag by utilizing the NFC reader 22 of.

For reference, the NFC reader 22 corresponds to a device configured to obtain a unique identification code (in this case, UID and UUID) of a product stored in the second tag by tagging the second tag, for example, the NFC reader As 22, a wireless barcode scanner can be utilized. The wireless barcode scanner can continuously scan the barcode and NFC data without separate manipulation, and, for example, the code of the second tag can be continuously acquired without separate manipulation through non-contact tagging or scanning.

When the UID is read from the second tag by the NFC reader 22 (S430), the UUID generating unit 21 of the manufacturer terminal 20 may generate a UUID using the UUID generating process from the read UID (S440). ). Here, according to a preferred embodiment of the present invention, the operation of reading the UUID from the second tag (S420) and the operation of reading the UID from the second tag and generating the UUID therefrom (S430 and S440) may be performed simultaneously. Thereafter, the control unit 23 may compare the UUID read from the second tag with the UUID generated by the UUID generation unit 21 (S450).

As a result of the comparison of the control unit 24, when the UUID read from the second tag and the UUID generated by the UUID generating unit 21 do not match, this means that the UUID generating unit 21 provided in the manufacturer terminal 20 is tagged It means a unit that is not supplied through a formal contract or the like from the producer of the generating terminal 10, or means that the manufacturer of the tag generating terminal 10 illegally uses a unit supplied to another manufacturer, etc. The step ends (S460). Here, according to a further embodiment of the present invention, the information that the UUID read from the second tag and the UUID generated by the UUID generating unit 21 do not match may be transmitted to the tag generating terminal 10 (for example, For example, in an alarm or the like), accordingly, the producer of the tag generating terminal 10 can immediately recognize the use of the non-genuine tag.

Conversely, as a result of comparison of the control unit 24, when the UUID read from the second tag and the UUID generated by the UUID generation unit 21 match, this means that the UUID generation unit 21 provided in the manufacturer terminal 20 is It means that it corresponds to the unit supplied through the formal contract from the manufacturer of the tag generating terminal 10, and thus, the PID is added to the second tag (S470) to activate the ID information (ie, UID, UUID and PID). Upload to the server 30 and write to the tag (S480). In this case, the NFC reader 22 may register by writing the Internet resource (URI) of the genuine authentication server 30 in which the corresponding product information is registered to the corresponding tag.

As described above, in contrast to the conventional method in which the manufacturer terminal 20 registered the product by simply using the UID, according to the NFC tag-based product registration and authentication method according to an embodiment of the present invention, the UUID is added to the tag. By additionally performing a process for confirming whether the corresponding tag itself is genuine before writing the PID information (for example, by comparing the UUID read from the second tag with the UUID generated by the UUID generating unit 21) The use of non-genuine NFC tags can be fundamentally blocked.

For reference, the product activation server 30 may register at least one UID/UUID information and product information received from the manufacturer terminal 20 in the storage unit 31, and product information registered in the storage unit 31. The Internet identifier (URI) may be assigned to the Internet identifier (URI), where the product information is registered as information including an Internet address (URL; uniform resource locator) and an Internet name (URN). You can include the path and storage name. When registration is completed, the activation server 30 may transmit a registration completion message to the manufacturer terminal 20 together with an Internet identifier (URI), and from then on, the activation server 30 may display the product based on the updated data. Activation can be performed.

5 is a schematic flowchart for explaining genuine product activation (S500) in the consumer terminal 40. 2 and 5, the process of activation (S500) in the consumer terminal 40, which is configured to perform activation of a product that has been genuinely registered by the manufacturer terminal 20, is exemplified. Is described. The consumer terminal 40 is equipped with an NFC function, and thus may be configured to authenticate a genuine product through an NFC tag attached to the product.

More specifically, when the genuine product verification is started in the consumer terminal 40 (S510), the genuine product authentication unit 42 reads the UID, UUID, and PID from the tag registered genuinely by the manufacturer terminal 20 (S520). Retrieves the UID, UUID and PID uploaded to the authentication server 30 (S530), compares the read UID, UUID and PID with the retrieved UID, UUID and PID (S540), and matches if genuine The authentication may be output (S560). In addition, the activation unit 42 may compare the read UID, UUID, and PID with the retrieved UID, UUID, and PID (S540) and terminate activation if they do not match (S550).

For reference, in the example of FIG. 5, the read UID, UUID and PID are compared with the retrieved UID, UUID and PID, but in another embodiment of the present invention, (i) the read UID and UUID and the retrieved UID and The consumer terminal 40 may be configured to perform activation by comparing the UUID or (ii) the read UUID and PID and the retrieved UUID and PID.

As described above, according to the NFC tag-based activation system and method according to an embodiment of the present invention, it is possible to improve the consumer's confidence in the activation product by fundamentally blocking the use of an illegally copied NFC tag. have.

In addition, according to the NFC tag-based activation system and method according to an embodiment of the present invention, in generating an NFC tag, as well as the product's unique identification code (UID), an additional second code (eg, UUID) ), it is possible to prevent third-party illegal copying of the NFC tag, and accordingly, it is possible to reliably guarantee the use of the genuine tag to the consumer.
