FIG. 1 is a flowchart illustrating an NFC tag issue method for authenticating an authenticity among NFC-based authenticity authentication service providing methods of a system according to an embodiment of the present invention.

Referring to FIG. 1, the system includes a tag writer 10, an NFC tag 30, and an authenticity authentication server 40.

The tag writer 10 transmits the uID request signal requesting the uID to the NFC tag 30 in order to provide an authenticity authentication function to the user by using the NFC tag 30 (S10). The uID indicates a unique ID scheme provided by the manufacturer of the NFC chip of the NFC tag 30. The NFC tag 30 transmits the uID to the tag writer 10 in response to the uID request signal (S11).

The tag writer 10 transmits the uID received from the NFC tag 30 to the authenticated authentication server 40 (S12). According to an embodiment, the tag writer 10 can transmit the uID to the authenticated authentication server 40 in a Secure Sockets Layer (SSL) manner.

The genuine product authentication server 40 generates a tag ID and a dKey, and stores the uID, the tag ID, and the dKey in the database 49 of the authenticity authentication server 40 (S13). According to the embodiment, the product unique number or product manufacturing date for authenticating the product can be stored in the database 49 of the authenticity authentication server 40 in a one-to-one correspondence with the uID, the tag ID, and the dKey.

The tag ID is generated by combining arbitrary numbers to prevent duplication, copying, or hacking of the authenticity of the authenticity. The dKey may be generated by combining the number of the uID and the number of the tag ID. The tag ID and the dKey are generated and managed for each product.

Specifically, the dKey can be generated using the master key stored in the authenticity authentication server 40. [ The master key is stored only in the authenticating server 40, so that security risks such as hacking can be minimized.

The authenticity authentication server 40 transmits the tag ID and the dKey to the tag writer 10 (S14).

The tag writer 10 transmits a tag writer request signal requesting the NFC tag 30 to write the tag ID and the dKey to the NFC tag 30 (S15). In response to the tag writer request signal, a writer operation of writing the tag ID and the dKey to the NFC tag 30 is performed (S16). After the writer operation is performed, the NFC tag 30 transmits the writer result to the tag writer 10 (S17), and the tag writer 10 transmits the writer result to the genuine article authentication server 40 (S18) .

2 is a flowchart illustrating an authenticity authentication method for a product authentication attempt in a method of providing an authenticity authentication service based on an NFC tag in a system according to an embodiment of the present invention.

Referring to Figures 1 and 2, the system may further include a terminal 20. According to an embodiment, the system may comprise a plurality of terminals and a plurality of NFC tags.

An application for using the NFC tag based authentification service can be installed in the terminal 20. [ The mobile web may be used in the terminal 20 to utilize the NFC tag based authentification service according to the embodiment. In this specification, the terminal 20 may specifically refer to an application installed in the terminal 20 or a mobile web.

A user selects a product using the application installed in the terminal 20 or the mobile web, and tags the NFC tag attached to the selected product to transmit a signal requesting the uID and the tag ID for authenticating the authenticity to the NFC tag 30 (S20). The NFC tag 30 transmits the uID and the tag ID to the terminal 20 in response to the request signal (S21).

The terminal 20 transmits the uID and the tag ID transmitted to the terminal 20 to the authenticated authentication server 40 (S22). The terminal 20 may transmit the uID and the tag ID to the authenticated authentication server 40 in a secure sockets layer (SSL) manner.

The authenticity authentication server 40 compares the tag ID stored in the database 49 of the authenticity authentication server 40 with the tag ID transmitted from the terminal 20 (S23). When the tag ID stored in the database 49 of the authenticity authentication server 40 matches the tag ID transmitted from the terminal 20, the authenticity authentication server 40 authenticates the authenticity authentication server 40 ) To the terminal 20 (S24). According to the embodiment, the genuine product authentication server 40 can transmit the dKey to the terminal 20 in a Secure Sockets Layer (SSL) manner.

3 is a flowchart illustrating an authenticity authentication method between a user terminal and an NFC tag in a method of providing an authenticity authentication service based on an NFC tag in a system according to an embodiment of the present invention.

Referring to FIG. 3, the terminal 20 transmits a settlement authentication request signal to the NFC tag 30 (S30). The NFC tag 30 generates a random number in response to the authenticity request signal (S31), and transmits the generated random number to the terminal 20 (S32).

The terminal 20 encrypts the random number using dKey2 (S33), and transmits the encrypted random number to the NFC tag 30 (S34).

The NFC tag 30 decrypts the encrypted random number using the stored dKey, and compares the random number stored in the NFC tag 30 with the encrypted random number transmitted from the terminal 20 (S35).

The NFC tag 30 transmits a genuine authentication result signal to the terminal 20 when the random number stored in the NFC tag 30 and the encrypted random number transmitted from the terminal 20 are equal (S36). The NFC tag 30 transmits an error signal to the terminal 20 when the random number stored in the NFC tag 30 and the encrypted random number transmitted from the terminal 20 are not equal to each other (S36)

Fig. 4 shows a schematic block diagram of the authenticity authentication server shown in Fig. 1. Fig.

1 to 4, the genuine product authentication server 40 includes a tag ID generation module 41, a dKey key generation module 43, a delivery module 45, a tag ID comparison module 47, And a database 49 of the database 40.

As used herein, a module may refer to a functional or structural combination of hardware to perform the authentication method or software that can drive the hardware according to an embodiment of the present invention. Thus, the module may refer to a program code and a logical unit or set of hardware resources that can execute the program code.

The tag ID generation module 41 generates an arbitrary number by the genuine product authentication server 40 to generate a tag ID and stores the generated tag ID in the database 49 of the genuine product authentication server 40. [ And transmits the tag ID to the dKey generation module 43.

The dKey generation module 43 generates a dKey by combining the number of the uID and the tag ID number, and stores the generated dKey in the authenticity authentication database 49. At this time, a dKey corresponding to the corresponding NFC tag 10 on a one-to-one basis is generated using the master key stored in the server only.

The delivery module 45 receives the dKey and the tag ID stored in the authenticity authentication database 49 and transmits the dKey and the tag ID to the tag writer 10.

The tag ID comparison module 47 compares the tag ID stored in the database 49 of the authenticity authentication server 40 with the received tag ID using the tag ID and the uID transmitted from the terminal 20. The tag ID comparison module 47 transmits the dKey stored in the database 49 to the terminal 20 when the tag ID stored in the database 49 and the tag ID transmitted from the terminal 20 match. The genuine product authentication data base 49 stores and manages the uID, the tag ID, and the dKey corresponding one-to-one with the product unique number.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
