The present invention relates to a genuine article identification service, and more particularly, to a genuine article identifying NFC tag management system for identifying a genuine article by discriminating whether an NFC tag is illegally copied or not.

Unlike a conventional barcode, a tag used in an RFID system can read information stored in a chip wirelessly using a semiconductor chip, and can record new contents.

In particular, it is a non-contact type technology and it is possible to transmit and receive long distance information, so that many tag information can be simultaneously read at the same time, and recognition speed is also very high, which can secure a considerable advantage in terms of work efficiency. The biggest advantage of RFID technology is that the amount of information that can be recorded on the tag has increased dramatically compared to other media. As the amount of information stored increases, various kinds of information such as product information and production information can be stored. Recently, Near Field Communication (NFC), which is a kind of RFID technology, is receiving attention.

Near Field Communication (NFC) is a non-contact communication technology that uses the frequency band of 13.56 MHz as one of radio frequency identification (RFID) technologies. It is a next-generation LAN technology that is attracting attention due to its relatively low security and relatively low price because of its short communication distance. Because it can use both data reading and writing functions, it does not need reader that is needed for general RFID use, and it is similar to conventional short distance communication technology such as Bluetooth, but it does not need to set between devices like Bluetooth.

Due to this feature of RFID technology, RFID tags or NFC tags are being applied to distribution systems for identifying fake or counterfeit goods of luxury goods such as premium wines such as whiskey, vodka, golf clubs, jewelry, bags, watches and the like.

1 is a block diagram of a genuine identification NFC tag management system according to the present invention.

1, the NFC tag management system according to the present invention includes a purchaser terminal 100, an NFC tag 200, a seller terminal 300, and a server 400.

The purchaser terminal 100 reads the unique number and the encrypted product information from the NFC tag of each product to determine whether or not the product is registered formally.

The purchaser terminal 100 is a portable terminal such as a mobile phone, a PDA, a smart phone or a communication terminal and includes an NFC modem (chip), a wireless communication unit, an A / V (audio / video) input unit, a user input unit, A memory, an interface, a controller, a power supply, and the like, and not all of these elements are essential, and may include elements having more or fewer elements.

The purchaser terminal 100 includes a device capable of reading an NFC tag, and an application (hereinafter referred to as a "service app") for identifying whether or not the tag is illegally copied is read from the read NFC tag information in a memory Can be stored. In the case of a service application (app), a purchaser can download and install it from the server 400 or an application store (hereinafter referred to as an 'App store'). The service application (app) is downloaded by the purchaser in advance and installed in the terminal 100.

The purchaser visiting the shop (or dealer) according to the present invention scans (approximates touches) the purchaser's terminal 100 with the article being sold (with NFC tag) to detect the product information or discriminate whether it is an illegal copy do.

The buyer terminal 100 reads the unique number and the encrypted product information from the NFC tag when the proximity touch with the NFC tag attached to the product is detected. Then, the inherent number is applied to a random number generation algorithm to generate a cryptographic key. Then, the purchaser terminal 100 applies the encryption key to the encryption algorithm to decrypt the encrypted product information. If the decryption of the product information is normally performed, the decrypted product information is displayed. If an error occurs in the decryption, the buyer terminal 100 displays a forgery product display message.

The NFC tag 200 is a product of the tag unique information (or a unique identification code) and products of producers (sellers) that are supplied (circulated) to the market (e.g., high quality wine, golf clubs, jewelry, Information (for example, information such as product name, product code, manufacturer, date of manufacture, distribution route, manufacturing country, and reference information) is stored in the memory. The NFC tag 200 transmits information stored in the tag (e.g., tag specific information, encrypted product information, etc.) to the mobile terminal 200 when the NFC tag 200 is touched to the purchaser terminal 100. [

The seller terminal 300 accesses the server 400, performs a predetermined authentication procedure, and encrypts the activation NFC tag to be attached to the product using the unique number (or unique identification code) of the NFC tag .

The seller terminal 300 may be a portable terminal such as a mobile phone, a PDA, a smart phone, or a communication terminal, and may have the same or lesser components than the buyer terminal 100.

The seller terminal 300 also has a device capable of reading an NFC tag, and can store an application (hereinafter referred to as a 'service app') for creating a read NFC tag in a memory. At this time, the service app (app) of the seller terminal may be developed only for the seller terminal 300, which is different from that of the buyer terminal 100.

In the case of a service application (app), a seller can download and install the application from the server 400 or an application store (hereinafter referred to as an 'App store').

The service application (app) is downloaded by the seller in advance and installed in the terminal 300. In the installation process (or first time execution), the seller registers the seller's membership information (e.g., authentication code, license key, etc.) with the service app.

The seller terminal 300 first executes a service application, detects its own device number, and applies the detected unique number to a random number generation algorithm to generate a cryptographic key. Then, the encryption key is applied to the encryption algorithm to decrypt the encrypted authentication code and license stored in the memory.

Then, when the server 400 receives an authentication acceptance message from the server 400, the server 400 requests authentication using the decrypted authentication code and the license key. . Then, the product information of the product is inputted from the manager.

The seller terminal 300 generates the encryption key by applying the tag unique number to the random number generation algorithm, and encrypts the inputted product information by applying the generated encryption key to the encryption algorithm. Then, the encrypted product information is written in the NFC tag 200, and the status value of the tag is set to read only, thereby preventing editing or forgery of the stored information.

In order to provide a genuine identification service using the NFC tag, the server 400 generates an authentication code for each vendor and issues a license key for each authentication code.

The server 400 distributes an application (or a service application) for identifying illegal copying of an NFC tag or an NFC tag to an application purchasing destination such as an Android market or an application store, thereby providing a user (hereinafter referred to as a 'buyer or a seller' To use the genuine article identification service according to the present invention.

When the seller requests authentication using the authentication code and the license key after accessing through the service application, the server 400 returns the authentication wait message and waits for the seller terminal 300 to wait until the authentication acceptance of the administrator drops .

Thereafter, when the administrator accepts the authentication request from the seller side, the authentication wait state is changed to the authenticable state, and then the seller transmits a push message to the seller terminal 300 so as to retry the authentication request. When the authentication request message is received from the authentication server 300, the authentication acceptance message is returned to allow the seller to create the activation NFC tag using the service application.

2 is a block diagram of a purchaser terminal according to the present invention.

The wireless communication unit 110 may include at least one component for wireless communication between the purchaser terminal 100 and the wireless communication system or wireless communication between the purchaser terminal 100 and the network in which the purchaser terminal 100 is located. For example, the wireless communication unit 110 includes a broadcast receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short distance communication module 114, a location information module 115, an NFC modem 116 ). ≪ / RTI >

The short-range communication module 114 is a communication module that communicates with a nearby electronic device. Examples of applicable short range communication technologies include Bluetooth, Radio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), and ZigBee.

The sensing unit 140 senses the current state of the purchaser terminal 100 such as the open / close state of the purchaser terminal 100, the location of the purchaser terminal 100, the presence of the user, the orientation of the purchaser terminal, And generates a sensing signal for controlling the operation of the purchaser terminal 100. For example, when the buyer terminal 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. Also, it is responsible for a sensing function related to whether or not the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like.

When the purchaser terminal 100 is connected to an external cradle, the interface unit 170 may be a path through which the power from the cradle is supplied to the buyer terminal 100, The command signal may be a channel through which the buyer terminal 100 is delivered. The various command signals or the power source inputted from the cradle may be operated as a signal for recognizing that the purchaser terminal is correctly mounted on the cradle.

The output unit 150 generates an output related to a visual, auditory or tactile sense. The output unit 150 may include a display unit 151, an audio output module 152, and an alarm unit 153.

The display unit 151 displays and outputs information processed by the purchaser terminal 100. For example, the UI of the service application (User), which indicates that the buyer terminal 100 scans (touches proximity) an NFC tag and displays the resulting message (e.g., "is an activation NFC tag" Interface) or GUI (Graphic User Interface). When the buyer terminal 100 is in the video communication mode or the photographing mode, the captured image and / or the received image or UI and GUI are displayed.

The display unit 151 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a three-dimensional display 3D display).

There may be two or more display units 151 according to the embodiment of the purchaser's terminal 100. [ For example, in the buyer terminal 100, a plurality of display portions may be spaced apart from one another or disposed integrally with each other, and may be disposed on different surfaces.

The display unit 151 may include a display unit 151 and a touch sensor 160. The display unit 151 may be a touch screen, It can also be used as an input device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The sound output module 152 outputs audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, and a broadcast reception mode. In addition, the sound output module 152 outputs an acoustic signal related to the functions (e.g., call signal reception sound, message reception sound, etc.) performed in the buyer terminal 100. [ The audio output module 152 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the buyer terminal 100 of the occurrence of an event. Examples of the event include a call signal reception, a message reception, a key signal input, a touch input, and the like. The alarm unit 153 may output a signal for notifying the occurrence of an event in a form other than an audio signal or a video signal, for example, by vibration. The video signal or the audio signal may be output through the display unit 151 or the audio output module 152 so that they may be classified as a part of the alarm unit 153.

The memory 160 may store a program for processing and control of the controller 180 and may store input / output data (e.g., a phone book, a message, a still image, a moving image, Code, license key, etc.).

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM (Random Access Memory) SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read- And an optical disc. In addition, the purchaser terminal 100 may operate a web storage that performs a storage function of the memory 160 on the Internet.

The controller 180 controls the operations of the terminal in cooperation with the respective components 110, 120, 130, 140, 150, 160, 170, 180 and 190 of the terminal.

The control unit 180 reads the unique number and the encrypted product information from the NFC tag when the proximity touch with the NFC tag attached to the product is detected. Then, the unique number is applied to a predetermined random number generation algorithm (e.g., a random number generation module 184) to generate a cryptographic key. Then, the control unit 180 applies the encryption key to an encryption algorithm (e.g., encryption algorithm 188) to decrypt the encrypted product information. If the decryption of the product information is normally performed, the decrypted product information is displayed on the display unit 151. If an error occurs in the decryption, that is, if the NFC tag attached to the product is illegally copied, the control unit 180 controls the display unit 151 to output the forged product indication message.

The random number generation module 184 generates a cryptographic key by applying the unique number of the tag to the key value of random number generation.

The encryption module 188 decrypts the product information using the generated encryption key.

The random number generation module 184 and the encryption module 188 may be separate independent devices or algorithms dependent on the control unit 180.

On the other hand, when mounted on the seller terminal 300, the controller 380 operates differently from that mounted on the buyer terminal 100. [

The control unit 380 implemented in the seller terminal 300 first executes the service application and detects the device unique number of the terminal 300 and transmits the detected unique number to the random number generation algorithm (e.g., the random number generation module 384) To generate an encryption key. Then, the encryption key is applied to an encryption algorithm (e.g., encryption module 388) to decrypt the encrypted authentication code and license stored in the memory.

The control unit 380 requests the server 400 to authenticate the server 400 using the decrypted authentication code and the license key. When the authentication acceptance message is received from the server 400, the controller 380 performs an NFC And detects the tag unique number. Then, the product information of the product is inputted from the manager.

The control unit 380 applies the tag unique number to the random number generation algorithm to generate an encryption key, and applies the generated encryption key to the encryption algorithm to encrypt the inputted product information. Then, the encrypted product information is written in the NFC tag 200, and the status value of the tag is set to read only, thereby preventing editing or forgery of the stored information.

The control unit 180 or 380 may be implemented in software and an application such as a service application implemented in software by the control unit 180 or 380 may be provided from an application source such as an Android market or an application store And the user downloads the app (app 180 (380)) in advance and installs it in the smart communication device 100, 300.

The terminals 100 and 300 according to the present invention can automatically execute the service app when the NFCD tag 200 is detected within a predetermined distance. In the case of the seller terminal 300, the user can access the server 400 through the service application and receive the genuine identification service provided by the server 400. [

As shown in FIG. 4, the server 200 according to the present invention generates an authentication code for each vendor and issues a license key for each authentication code to provide a genuine identification service using the NFC tag. (S110 to S120)

When the authentication code and the license key are issued, the seller terminal 300 executes the service application (first execution), and inputs the authentication code and the license key issued from the server 400. [ (S130 to S140), and transmits the input authentication code and license key to the server 400 and requests authentication of the service membership. (S150)

The server 400 receiving the authentication request through the service app returns to the authentication wait message once and waits for the seller terminal 300 to wait until the authentication acceptance of the server administrator drops. (S160)

The seller terminal 300 temporarily stores the status value (e.g., authentication wait message, authentication code, license key) in the memory once the authentication wait message is received from the server 400. [

When the manager accepts the authentication request from the seller side, the server 400 changes the authentication wait state to the authenticatable state and then transmits a push message to the seller terminal 300 ). (S180 to S190)

The seller terminal 300 receiving the push message transmits the temporary stored authentication code and the license key to the server 400 (automatically), and requests the service membership authentication again. (S200), the server 400 accepts the authentication request of the seller side (S220), and the seller side terminal 300 confirms the authentication acceptance of the server 400 and then prohibits the unauthorized copying of the service application Encrypts the authentication code and the license key with their own device number as a cipher key, and stores the encrypted code. (S230)

The present invention encrypts and stores the authentication code and the license key issued to the seller side using the device unique number of the seller terminal 300 as the encryption key when the server 400 accepts the service membership authentication request from the seller side, To prevent malicious unauthorized copying.

Then, when the storage of the authentication code and the license key is completed, the creation of the NFC tag to be attached to the commodity is started. (S240)

5 is a flowchart illustrating a procedure for preventing unauthorized copying of the service application.

As shown in FIG. 5, the seller terminal 300 first detects its own device number. (S232) Then, the detected unique number is applied to the random number generation algorithm to generate an encryption key, and the generated encryption key is applied to the encryption algorithm to encrypt the authentication code and the license key. (S234 to S236)

Then, the seller terminal 300 stores the encrypted authentication code and the license key in a memory.

6 is a flowchart illustrating an operation of the seller terminal according to the present invention.

As shown in FIG. 6, the seller terminal 300 according to the present invention first executes a service application (S310), detects its own device number, applies the detected unique number to a random number generation algorithm, . (S320)

Then, the encryption key is applied to the encryption algorithm to decrypt the encrypted authentication code and the license key stored in the memory. (S330)

When the server 400 receives the authentication acceptance message from the server 400 in step S350, the server 400 requests the authentication of the server 400 by using the decrypted authentication code and the license key Touch to detect the tag unique number. (S360) Then, as shown in FIG. 7A, the product information of the product is received from the manager. (S370) FIG. 7A is an exemplary view showing a product information input screen of the service app according to the present invention.

The seller terminal 300 generates the encryption key by applying the tag unique number to the random number generation algorithm, and encrypts the inputted product information by applying the generated encryption key to the encryption algorithm. (S380 to S390), the encrypted product information is written to the NFC tag 200, and the status value of the tag is set to read only to prevent editing or forgery of the stored information. (S400)

If the executed service application is maliciously copied illegally to a terminal of another person, an encryption key to which the device unique number of the other terminal is applied is generated in the above steps S320 to S330, and the authentication code and the license key are decrypted. The server 400 in the authentication requesting process (S340) recognizes that the decrypted authentication code and the license key are different from those issued, rejects the authentication acceptance, or returns an error message.
