Referring to FIG. 1, the customized product providing system may include a client 100, a decryption server 110, a communication terminal 120, a meta information processing server 130, and a service processing server 140. However, since the customized product providing system of FIG. 1 is only an embodiment of the present invention, the present invention is not limitedly interpreted through FIG. 1 and may be configured differently from FIG. 1 according to various embodiments of the present invention. .

In general, each component of the customized product providing system of FIG. 1 is connected via a network 170. The network refers to a connection structure capable of exchanging information between respective nodes such as terminals and servers. Examples of such a network include 3G, 4G, 5G, 3rd Generation Partnership Project (3GPP), and LTE (Long). Term Evolution, World Interoperability for Microwave Access (WIMAX), and Wi-Fi.

The secured QR code 150 may be provided inside or outside the store 160, and may be processed such that the QR code 150 may be decrypted only at the store 160. In another embodiment, the secured QR code 150 may be printed on the physical product sold in the store 160. Details thereof will be described later.

The client 100 may first decrypt the secured QR code 150 provided in the store 160 to generate or extract an encrypted server side message and a Uniform Resource Locator (URL) of the decryption server 110. .

The secured QR code 150 may be a primary code that can be firstly decrypted through a specific application installed in the client 100, and may be a security code that is binarized and encrypted in a form capable of secondary decryption through the decryption server 110. . For example, the secured QR code 150 may obtain a unique decryption key through a specific application installed in the client 100, and may be decrypted only through the obtained unique decryption key. The encrypted server side message generated by first decrypting the secured QR code 150 may be configured to be decrypted only through a unique key of the decryption server 110. When the client 100 photographs the secured QR code 150 through an application other than a specific application, a customized product providing service may not be provided. Unlike the conventional QR code that provides only a function corresponding to the code by reading only the code corresponding to the QR code, the present invention allows decoding only through a specific application installed on the client 100, so that the code can be read through one QR code. In addition to the corresponding functions, more diverse and more secure functions can be provided.

In addition, by performing the primary decryption through a specific application installed in the client 100, and performing the secondary decryption through the decryption server 110, it is possible to further enhance the security. The secured QR code 150 may be configured to provide, for example, a customized product (eg, product information, promotion information, discount information, etc.) in a predetermined form for each sales purpose for each store. For example, a secured QR code at store A and a secured QR code at store B may provide different kinds of merchandise. For example, the secured QR code 150 may be a QR code 150 corresponding to a game item for selling a game item provided in a random form in a PC cafe. For example, the secured QR code 150 may be set to provide a service related to a game item only during a specific service providing time range. The type of the service, the type of the customized product, and the set condition may be set and changed through the action key value of the server side message, which will be described later.

Even if the secured QR code 150 is stolen in an arbitrary place due to illegal shooting or the like, the customized product service may be limited based on the location of the client 100.

The client 100 may transmit a service request including an encrypted server side message and identification information of the client 100 to the decryption server 110 through the URL of the decryption server 110.

The client 100 may transmit the location information of the store 160 obtained from the communication terminal 120 installed in the store 160 to the decryption server 110. The communication terminal 120 may be, for example, a terminal equipped with a Global Positioning System (GPS) module that calculates a location of the communication terminal 120, and transmits a beacon signal to the client 100 entering the beacon area. It may be a beacon (Beacon) device for transmitting and receiving, and may be an AP (Access Point) device for providing a wireless network access to the client 100 located in the store 160. The communication terminal 120 may be used to identify the location of the store 160 and may be used to block illegal use at any place by photographing the secured QR code 150 or the like. For example, it may be understood that the client 100 enters the store 160 through the communication terminal 120.

For example, the location information of the store 160 may be identified through the beacon ID received by the decryption server 110 from the client 100. In addition, it may be identified using a fixed IP received through an access point (AP) device and the location coordinates of the store 160 through the GPS module.

The client 100 may include a mobile terminal capable of wireless communication, and according to various embodiments of the present disclosure, the client 100 may be various types of devices. For example, the client 100 may be a portable terminal capable of connecting to a remote server through a network. Here, an example of a portable terminal is a wireless communication device that ensures portability and mobility, and includes a smartphone, a tablet PC, a personal communication system (PCS), a global system for mobile communications (GSM), and a personal digital cellular (PDC). , Personal Handyphone System (PHS), Personal Digital Assistant (PDA), International Mobile Telecommunication (IMT) -2000, Code Division Multiple Access (CDMA) -2000, W-Code Division Multiple Access (W-CDMA), Wireless Broadband All types of handheld based wireless communication devices such as Internet terminals may be included. However, the client 100 is not limited to the form illustrated in FIG. 1 or those illustrated above.

The decryption server 110 may secondly decrypt the server side message included in the service request to extract service information. Here, the service information may include, for example, operation information indicating the type of service, coupon information on the service, store information, and the like.

The decryption server 110 determines whether the client 100 satisfies a preset condition for the secured QR code 150 based on at least one of the service information extracted from the server side message and the location information of the store 160. You can judge. Such a condition may be included in operation information of the secured QR code 150.

The decryption server 110 may determine whether the client 100 satisfies a preset condition for the secured QR code 150 through the meta information processing server 130.

For example, the decryption server 110 determines whether the time for the service request of the client 100 corresponds to the service providing time range preset in the secured QR code 150, and then user meta information and real time meta information. You can request For example, the decryption server 110 may transmit service information, location information, and identification information of the client 100 to the meta information processing server 130, and may request user meta information and real time meta information. The user meta information may include, for example, one or more of a user's purchase history, a purchase pattern, and a purchase preference, and the real time meta information may include, for example, one or more of store information, period information, region information, and promotion information. Can be.

The decryption server 110 receives the server side message generated by the client 100 when the secured QR code 150 stored in the store 160 is first decrypted by the client 100. After the second decoding, the client 100 may check whether the client 100 satisfies the preset condition, and provide the customized product to the client 100 when the client 100 satisfies the preset condition. For example, when the client 100 satisfies a predetermined condition, the decryption server 110 may customize a product (eg, a selected brand name and price information) to the client 100 based on user meta information and real time meta information. Can be provided.

The decryption server 110 may change the configuration of the customized product for each store 160 based on at least one of store information, period information, region information, and promotion information. For example, if the store 160 for the service request is a new store, the decryption server 110 may increase the probability of the top ranked high order product in the random set product, or may provide a special service provided only at the store 160. Can provide goods. As another example, when the store 160 for the service request belongs to a specific region, the decryption server 110 slightly increases or increases the probability of the top ranked product in the random set product or provides only in the store 160. Can provide special products.

In addition, the decryption server 110 may store additional event products (eg, discount coupons, merchandise vouchers, points, etc.) provided by the store 160 based on at least one of store information, period information, region information, and promotion information. The search may be provided to the client 100.

In another embodiment, the decryption server 110 may be configured to client-side a server-side message generated by the client 100 having the secured QR code 150 included in the real product sold in the store 160 being first decrypted by the client 100. If received from the 100, after the second decoding of the server-side message, it is determined whether the client 100 satisfies the predetermined condition, and if the client 100 satisfies the predetermined condition, the client 100 sends a QR to the client 100. The predetermined product corresponding to the coupon information about the service included in the code 150 may be provided. Here, the procedure of determining whether the client 100 satisfies a predetermined condition may be omitted according to the physical product sold in the store 160.

As such, unlike the conventional QR code that merely provides a function corresponding to the code, the secured QR code 150 of the present invention is store-specific based on service information, location information, and identification information of the client 100. For example, it is possible to easily change the service provided by region or time to enable more effective marketing.

The meta information processing server 130 receives the location information of the store 160, the service information, and the identification information of the client 100 from the decryption server 110, and the client 100 transmits to the secured QR code 150. The determination result may be transmitted to the decryption server 110 by determining whether the predetermined condition (the purchase list of the client 100, the location of the store, etc.) is satisfied.

The meta information processing server 130 may be divided into a user meta information processing server (not shown) and a real time meta information processing server (not shown).

The meta-information processing server 130 is based on the service information and the identification information of the client 100, the behavior condition (for example, the purchase of a specific game item, etc.) preset in the QR code 150 secured by the client 100. ) May be determined to transmit the determination result to the decryption server 110.

The meta information processing server 130 extracts a user's purchase history (purchase product information, purchase time information, etc.), a visit history of the store 160, and the like based on the service information and the identification information of the client 100, and the decryption server. May transmit to 110.

The meta information processing server 130 may determine whether the client 100 is located in the store 160 based on the location information of the store 160, and transmit the determination result to the decryption server 110.

In another embodiment, the meta information processing server 130 may request information of a store 160 (store name, a store location, etc.) and a service request of the client 100 that the client 100 recognizes the secured QR code 150. Extract the time for and transfer it to the decryption server 110.

As such, by determining whether the client 100 is located in the corresponding store 160, the user of the client 100 may directly visit the corresponding store 160 to use the service provided by the store 160. can do. In addition, when a temporary promotion is carried out only in a specific store 160 or a specific region, the secured QR code 150 stored in the corresponding store 160 or a store located in a specific region is leaked to the Internet and used without permission. Can be prevented.

In addition, various promotions may be planned and provided through service request time and action conditions, and the user of the client 100 may induce interest in the corresponding service through such promotion.

The service processing server 140 may transmit the information on the customized product to the decryption server 110 based on the user meta information and the real time meta information received from the decryption server 110 or the meta information processing server 130. For example, the service processing server 140 may include a service (eg, a game service) preferred by the client 100, a purchase pattern of the user (eg, a low-priced game item purchase), a kind of purchased product (eg, a weapon item). A random product set suitable for the client 100 and the store 160 among a random product set configured by a preset internal algorithm based on at least one of a location and a store name of the store 160 and a service request time of the client 100. Select to transmit the brand name and price information to the decryption server (110).

For example, suppose that a game store sells game content to a client 100 that satisfies a condition set in a QR code secured at a first store. At this time, the predetermined condition is included in the operation information of the secured QR code, and may be configured differently for each store. For example, the operation information of the secured QR code includes a customer requesting a service within a preset service providing time range (for example, 18:00 to 22:00) among customers who visited the first store, and a predetermined behavior condition (for example, , A customer who purchased a game item A), and a customer located in the first store.

The client 100 may first visit the first store and decrypt the secured QR code provided in the first store through a specific application installed in the client 100.

The client 100 may transmit a service request including the encrypted server side message generated by primary decryption or extraction and identification information of the client 100 to the decryption server 110. In addition, the client 100 may transmit location information obtained from the communication terminal installed in the first store and ID information of the communication terminal to the decryption server 110. Alternatively, the communication terminal installed in the first store may directly transmit location information to the decryption server 110.

The decryption server 110 second decrypts the encrypted server side message included in the service request, the type of service (service provided by the first store) included in the service information from the server side message, and operation information (for the service). Sales method), and the ID of the secured QR code can be extracted.

The decryption server 110 checks whether the time at which the service request of the client 100 is received is within a preset service providing time range (determining a time condition) and then informs the meta information processing server 130 of the user's meta information and real-time meta. You can request information.

The meta-information processing server 130 may determine whether the user of the client 100 has previously purchased the A product (acting condition determination) based on the meta information of the user. In addition, the meta information processing server 130 may determine whether the client 100 is located at the first store (location condition determination) based on the location information.

The decryption server 110 may request a customized product to the service processing server 140 when the client 100 satisfies a condition set in the secured QR code. In contrast, when the client 100 does not satisfy the predetermined condition of the secured QR code, the provision of the customized product to the client 100 is limited.

Since various preset conditions (operational information of service information) are set in the secured QR code 150 according to the merchandise sales purpose of each store, it may cause user's attention and for a specific store selling a specific product. Can induce visits from users.

Hereinafter, the operation of each component of the customized product providing system of FIG. 1 will be described in more detail.

2 is a block diagram of the decryption server 110 shown in FIG. 1 according to an embodiment of the present invention.

Referring to FIG. 2, the decryption server 110 may include a service request receiver 200, a location information receiver 210, a decoder 220, a condition determiner 230, a customized product provider 240, and a DB 250. ) May be included. Here, the condition determiner 230 may include a time determiner 232, an action determiner 234, and a position determiner 236. The customized product providing unit 240 may include a meta information requesting unit 242. However, the decryption server 110 illustrated in FIG. 2 is only one implementation example of the present invention, and various modifications are possible based on the components illustrated in FIG. 2.

The service request receiving unit 200 may receive a request from the client 100 for a service provided through the secured QR code 150 provided in the store 160 or the secured QR code 150 printed on the real product. have.

In detail, the service request receiving unit 200 includes a service request including an encrypted server side message generated by the secure QR code 150 having been subjected to the first decryption by the client 100 and identification information of the client 100. May be received from the client 100. In this case, the secured QR code 150 may be configured to be decrypted only through a unique key of a specific application installed in the client 100. The encrypted server side message may be configured to be decryptable only through the unique key of the decryption server 110.

The decryption unit 220 may secondly decrypt the encrypted server side message to extract service information of the store 160. Here, the service information may include operation information indicating the type of service provided by the store 160 provided with the secured QR code 150, coupon information about the service, and store information.

Referring to FIG. 3, an encrypted server side message generated or extracted by the secured QR code 150 and the client 100 will be described.

Referring to FIG. 3, the secured QR code 150 includes a character 301 that is output when the secured QR code 150 is read through an application other than a specific application, and the client to be decrypted by the client 100. The side message 303 and a check code 305 to check for forgery may be included. Here, the client side message 303 may be, for example, a message encrypted using AES128 encryption / decryption technique, which is a standard symmetric key encryption scheme, and the check code 305 may be a checksum (generated through a modular operation).

The client side message 303 generated or extracted by the client 100 may include an encrypted server side message 307 and a uniform resource locator (URL) 309 of the decryption server 110. Here, the encrypted server side message 307 is a message that the client side message 303 is decrypted and decrypted, and is encrypted with a unique key of the decryption server 110.

Since the QR code 150 secured as described above is decrypted by a specific application of the client 100 and the decryption server 110 as a binary encryption security code, the random QR code 150 is randomly generated due to illegal shooting or the like. It can be used to prevent illegal use at the site.

The server side message decoded by the decryption server 110 may include service information including operation information 311 indicating the type of service, coupon information 313 for the service, and store information 315. Here, the operation information 311 is an action key value for, for example, sales information, event information, discount information, security information, etc. of a service provided by the store 160 provided with the secured QR code 150. Can be configured. Here, the sales information of the service may include a sales method (general sale, random sale) and a use condition (visual condition, behavior condition, location condition) of the customized product providing service.

The operation information 311 may be changed in real time according to the operating method of the store 160. For example, the secured QR code generation server (not shown) may change the operation information 311 and retransmit the decryption server 110. Alternatively, the decryption server 110 or the service processing server 140 may change the operation information 311. For example, the operation information 311 may be temporarily changed such that the event product is provided only at a specific time period or the probability of the higher ranked products of the random product set is slightly increased. In this case, after the corresponding time period, the operation information 311 may be changed again as before.

As described above, in the case of the conventional QR code, in order to change its function, a new QR code needs to be generated and distributed, but according to the present invention, by changing only the action key value of the secured QR code, You can easily change the function of the processed QR code. Accordingly, it is possible to flexibly change the type of service, the format of the service, the promotion, and the like provided through the secured QR code.

The coupon information 313 for the service may include, for example, a coupon key value of content to be sold and may include personal identification information. The store information 315 may include, for example, identifier information and location information of the store 160.

Referring back to FIG. 2, the location information receiver 210 may receive location information of the store 160 from the client 100 from the client 100 or the communication terminal 120 installed in the store 160.

The condition determiner 230 may determine whether the client 100 satisfies a condition set in the secured QR code 150 based on the service information and the location information of the store 160.

The time determining unit 232 may determine whether the time for the service request received from the client 100 corresponds to the service providing time range set in the secured QR code 150. For example, when the service providing time preset in the secured QR code 150 is set from the first time to the second time, the time determining unit 232 may provide a service of the client 100 who purchased the specific game item. It can be confirmed whether the request time falls within the range from the first time to the second time.

The behavior determination unit 234 may determine whether the client 100 satisfies a predetermined behavior condition in the secured QR code 150 through a user meta information processing server (not shown). For example, the behavior determination unit 234 may determine whether the client 100 has purchased the first game item from the service information of the store 160 and the identification information of the client 100. In addition, the behavior determination unit 234 may extract the game item purchase history in the PC cafe using the identification information of the client 100, and grasp the purchase pattern of the client 100 from the product purchase history.
