Description

SYSTEM, METHOD AND PROGRAM FOR DETECTING REPLICA BY CLIENT KEY BASED ON CLIENT KEY

The present invention relates to a fake product discovery system, method and program.

As fake or counterfeit goods are harmed both by consumers and producers (manufacturers), each local government has strongly cracked illegal distribution of counterfeit goods distributed in expensive luxury brand market. However, There is a limit in blocking the distribution of

Since the development of counterfeiting technology makes it difficult for consumers to identify counterfeit goods by the naked eye, recently, manufacturers have developed anti-counterfeiting devices or genuine goods identification devices that can discriminate the authenticity of products by combining various scientific technologies .

However, even if there is such an anti-counterfeiting system, there is a problem that a consumer who understands the anti-counterfeiting system does not easily understand how to identify a counterfeit article, or a separate apparatus or an expensive system is required for separate identification.

In addition, there are many cases where counterfeit goods (for example, overseas food products, cosmetics, etc.) are produced and distributed as well as high-priced luxury goods.

The present invention seeks to provide a system, method, and program for detecting a counterfeit product to inform a user of the possibility of counterfeit product when the same code as the counterfeit code is copied and attached to the counterfeit product.

It is another object of the present invention to provide a counterfeit product detection system, method, and program for preventing generation rules for an activation code from being generated, thereby preventing the same from being attached to a counterfeit product.

The problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems which are not mentioned can be clearly understood by those skilled in the art from the following description.

A method for discovering a counterfeit product based on a client key according to an embodiment of the present invention is a method for detecting a counterfeit product based on a client key when a first authentication code confirmation request is received from a first client, Issuing a reference client key, wherein the reference client key is assigned to a matching relationship between the first client and a reference activation code; When receiving an activation code confirmation request from a specific client, the authentication server receives a comparison target activation code and a comparison target client key from the specific client, and performs a comparison with the reference activation code and the reference client key Performing a comparison step; And guiding that the reference client key and the comparison target client key are already authenticated if the reference activation key and the comparison authentication code match and the reference client key and the comparison target client key do not coincide with each other, 1 < / RTI > client or a second client, wherein the second client is a client differentiated from the first client, and the reference activation code comprises: Wherein the comparison object activation code is an activation code received from the specific client, and the comparison object client key is a client key stored in the specific client.

In addition, the activation code confirmation request may be obtained by obtaining an identification mark attached to the article by the client, and transmitting the activation code extracted in the identification mark to the authentication server.

In addition, the identification mark may be a QR code provided in the article itself or the article package.

The comparison step may further include the steps of: comparing the reference activation code with the comparison target product activation code by the authentication server; And performing a comparison between the reference client key and the comparison target client key when the comparison between the reference activation code and the comparison authentication code is performed.

The method may further include the step of informing the authentication server of the counterfeit product to the specific client if the reference activation code and the comparison product authentication code do not match.

Receiving, by the authentication server, a request to confirm whether the article having the activation code is affixed from the specific client; And if the product requested by the specific client is a genuine product, the authentication server may notify the first client that the requested product is a counterfeit product for the first time.

Generating a new client key that matches the activation code assigned to the new article when the authentication server receives the activation code confirmation request for the new article from the first client; And requesting the authentication server to delete the existing client key and store the new client key in the first client.

In addition, when the activation request is received a plurality of times for the same client key, the authentication server may receive the location information data from the client that transmits the activation request for the same activation code.

In addition, the authentication server may generate a random key of a certain number of digits; Confirming whether the random key is already alive and matched to a particular article; If the random key corresponds to a newly generated key, matching the random key with a new product and assigning the random key to the activation code; And re-executing generation of the random key if the random key corresponds to the already generated key.

A client-key-based counterfeit product discovery program according to another embodiment of the present invention is combined with hardware to execute the above-mentioned client key-based counterfeit product discovery method, and is stored in a medium.

According to the present invention as described above, the following various effects are obtained.

First, even if the same activation code is copied and attached to the counterfeit product, the user can recognize the possibility of the counterfeit product based on whether or not the activation code is authenticated.

Second, counterfeit merchants can not identify the rules for creating activation codes, so counterfeit goods can be prevented from becoming genuine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a system, method, and program for detecting a fake product according to embodiments of the present invention will be described in detail.

1 is a configuration diagram of a fake product discovery system according to an embodiment of the present invention.

A fake product discovery system according to an embodiment of the present invention includes an authentication server 100, a first client 200, and a second client 300.

The authentication server 100 plays a role of giving a client key to each client. That is, the authentication server 100 issues a client key newly generated to a corresponding client in response to a client key issuance request from a specific client. The manner in which the authentication server 100 grants the client key to each client will be described in detail below.

The authentication server 100 determines information to be provided to each client based on the activation code and the client key, and a specific process for determining information to be provided will be described in detail below.

In addition, the authentication server 100 plays a role of generating an activation code. The activation code is a data value assigned to each article. In one embodiment, the authentication server 100 may generate and assign a different activation code to each article when N items corresponding to a specific article of a specific brand (i.e., a company) are shipped. The activation code assigned to each article can be made with a specific identification mark and affixed to each article or package. The identification mark may be attached to a surface of an article (e.g., a packaging surface of a cosmetic pack) produced by a barcode, a QR code, or the like, or a product included in a product transaction (e.g., a quality certificate) .

The first client 200 is a client provided with a specific article and requesting activation by first obtaining an identification mark corresponding to the activation code. That is, the first client 200 acquires a specific article and acquires an identification mark attached thereto (for example, captures an identification mark through a camera), thereby requesting the authentication server 100 to confirm whether the article is a genuine article to be. The first client 200 can extract the activation code included in the identification mark and transmit it to the authentication server 100. [

The second client 300 is a client that performs activation after the first identification mark is first obtained by the first client 200. The second client 300 may be another client device of the first user having the first client 200 or a client device held by a second user other than the first user. That is, the second client 300 transmits the activation code extracted from the identification mark to the authentication server 100, and transmits the activation code and the second client key (that is, And stores the received activation result in the display unit.

2 is a flowchart of a method of detecting a fake product according to an embodiment of the present invention.

Referring to FIG. 2, when a request to confirm a specific activation code is received from the first client 200 for the first time, the authentication server 100 transmits a first client key Generating and storing the first client key, and issuing the first client key to the first client 200 (S500); The authentication server 100 receives the activation code from the specific client and the client key stored in the client when receiving a confirmation request of the activation code from the specific client, Comparing the first client key with the first client key matched with the activation code (S600); If the client key stored in the terminal does not coincide with the one stored in the server, the step S700 of informing that the client key is an authentic genuine product. Hereinafter, a detailed description of each step will be described.

Counterfeit manufacturers can duplicate the activation code affixed to a particular article and distribute it to the counterfeit, which is the same item as the one with the activation code attached. For example, a manufacturer of a fake product that manufactures and distributes counterfeit goods for product A may obtain an activation code attached to one product corresponding to the product A (for example, purchase a genuine product for the manufacture of counterfeit goods Or a package of the genuine product that has been discarded after being used by another person, and obtains an activation code), and duplicate a plurality of copies. Thereafter, the manufacturer of the counterfeit product may distribute the copy of the product with a copy of the activation code.

In this case, the activation code attached to the counterfeit article (i.e., the activation code attached to the counterfeit) is the activation code stored on the authentication server 100, and the counterfeit article itself is also the same as the product having the actual activation code attached thereto , It is difficult for buyers to confirm that the goods are counterfeit goods. Therefore, there is a need for a method of preventing the counterfeit product from being circulated by reusing the already generated activation code. To this end, a client key may be utilized that represents the matching relationship between the article and the client (i.e., the terminal held by each user).

When authentication request of a specific activation code is received from the first client 200 for the first time, the authentication server 100 generates and stores the first client key, and issues the first client key to the first client 200 (S500). The authentication server (100) receives a specific activation code from the first client (200). As the first user acquires the identification mark attached to the purchased item using the first client 200, the first client 200 extracts the activation code from the identification mark. In one embodiment, when the identification mark is in the form of a QR code or a bar code, the first client 200 can photograph the identification mark with the camera by the operation of the first user to obtain the identification mark, Extract the authentication code. In another embodiment, when the identification mark is an NFC tag included in the article or the package of the article, the first client 200 may identify the genuine article included in the identification mark as tagged in the identification mark provided in the article by the first user The authentication code can be obtained. The first client 200 transmits the activation code to the authentication server 100 via wired / wireless communication.

Thereafter, the authentication server 100 first generates a client key that matches the corresponding activation code upon receipt of the activation code from the first client 200, and stores the generated client key in the authentication server 100. In other words, the client key is key data that is individually matched to each client device and the activation code.

Thereafter, the authentication server 100 transmits the generated client key to the first client 200, and the first client 200 internally stores the received client key. That is, when there is no client key generated by matching the activation code received from the first client 200, the authentication server 100 generates a client key corresponding to the activation code, and transmits the generated client key to the first client 200, .

When receiving a confirmation request for the activation code from a specific client, the authentication server 100 receives the activation code from the specific client and the client key stored in the client, and transmits a reference activation code (" 10) and the first client key matched with the reference activation code 10 (S600). That is, as a specific user recognizes the identification mark attached to the article using a specific client, the specific client can transmit a confirmation request of the extracted activation code to the authentication server 100. The specific client may be the first client 200 or the second client 300.

In one embodiment, the authentication server 100 receives the activation code (that is, the comparison object activation code) received from a specific client and one or more activation codes stored in the authentication server 100 ) And compares the client key received from the specific client (i.e., the comparison client key 40) with the reference activation code 10 stored in the authentication server 100 (i.e., Key 30). For example, the authentication server 100 may perform the comparison between the activation codes first, and may compare the activation codes of the comparison activation codes 10 and the comparison activation codes 20 if necessary (for example, And the comparison target product activation code 20 is included in the authentication code 10). If the comparison target product activation code 20 is not included in the one or more reference activation codes 10 stored in the authentication server 100, the product itself, which is requested to be validated by the specific client, is a counterfeit product, It is unnecessary to check whether or not the client device that has obtained the activation code matches.

If the activation key 100 matches the activation code (that is, the activation code corresponds to the code actually generated in the authentication server) and the client key stored in the terminal does not match the one stored in the server, (S700). That is, in the case of the first client 200 that first performed a confirmation request for a particular activation code, since the activation code and the client key match, the authentication server 100 determines that the activation code When a request for genuine confirmation is carried out again). On the other hand, if the activation key obtained from the specific client is stored in the server but the client key received from the specific client (that is, the comparison target client key 40) is a client key matched to the activation code (I.e., if the activation code attached to the article is present, but the activation is requested by the second client 300), the authentication server 100 first issues a validation request It can be determined that the client device is not the client device (i.e., the first client 200) performing the operation, and can be guided to be the " pre-authenticated activation code ".

In this case, when the validation is performed by the second client 300, which is another terminal of the same user as the first client 200 (that is, the first user), the user transmits the activation to the first client 200 It is possible to recognize what is displayed as the initial authentication. However, if the other user (i.e., the second user) is guided to the pre-authenticated code in the case of carrying out the validation on the counterfeit with the same activation code as the authentic product, the second user recognizes the possibility of the counterfeit . Generally, since the authentication process for the counterfeit product with the corresponding activation code is performed after the authentication process for the authentic product, it is possible to notify the users of the possibility of the counterfeit product through the different client key.

If a genuine validation request for a counterfeit product having the same activation code (that is, a counterfeit authentication code) as that of the genuine article is received first, it may be guided to the authenticated activation code for the user who actually purchased the genuine product. At this time, the authentication server 100 can receive a notification (for example, a request for confirming the authenticity) from the user who purchased the genuine product (i.e., the second user who has made the authentication code verification request with a subordination) The server 100 may determine that the article for which authentication was first performed (i.e., the article for which the first client requested the activation code verification by the first user) is a counterfeit article. At this time, the authentication server 100 can notify the first client 200 that the article that was activated by the first client 200 is a counterfeit article. That is, the authentication server 100 receives a request from the specific client to confirm whether or not the article having the activation code attached thereto is authentic; And guiding the authentication server 100 to the first client 200 that the first requested product is a counterfeit product when the product requested by the specific client is a genuine product, .

According to another embodiment of the present invention, when the first client 200 first requests the authentication code verification, the authentication server 100 notifies the first client 200 that the first client 200 is a counterfeit, Request the input of store information. Thus, the authentication server 100 can acquire the store information on the counterfeit goods from the purchaser who purchased the counterfeit goods.

3, if the comparison target product activation code 20 and the reference activation code 10 do not match, the authentication server 100 may further include a step S800 of informing the client that the product is a counterfeit product have. At this time, if the comparison target product activation code 20 and the reference activation code 10 do not match, the authentication server 100 compares the reference client key 30 and the comparison target client 30 matched to the reference activation code 10, Keys 40 may not be additionally performed. Since the activation code itself is not included in the authentication server 100, it is not necessary to determine whether the activation code is forgery code (that is, a code that has not been issued by the activation code). Therefore, the authentication server 100 is set to perform the comparison process between the reference client key 30 and the comparison target client key 40 only when the comparison object activation code 20 and the reference activation code 10 match .

In addition, in one embodiment, when it is determined that the authentication has been performed, the authentication server 100 calculates and stores the number of times the activation is performed. It is necessary for the authentication server 100 to know how many counterfeit goods are made and circulated with the activation code that has been affixed to the genuine article and circulated. Accordingly, the authentication server 100 can continuously calculate the number of clients for which the activation request is received for one activation code.

The authentication server 100 may provide the number of clients that made the activation request when receiving the activation request from each client. For example, when a user presents a gift, the gift provider can perform the activation process while purchasing the gift. When the gift acquirer performs the activation again after the activation by the gift provider is performed, if it is indicated that only the original is authenticated, it is indicated that it is displayed as the original authentication because it is authenticated by the gift provider, It is difficult to know whether or not it is. Accordingly, the authentication server 100 provides each client with the number of clients requesting activation of the corresponding activation code together with the 'basic authentication' fact information, and determines whether the activation is indicated by ' Can be predicted.

Also, in one embodiment, when receiving an activation request multiple times for the same activation code, the authentication server 100 receives the location information data from the client that transmits the activation request for the same activation code. Manufacturers / distributors of genuine products need to identify areas where counterfeit goods are distributed and take action. To this end, the authentication server 100 receives the current location information from the client requesting the activation of the previously authenticated activation code. The authentication server 100 accumulates location information received from a plurality of clients, and thus has an effect of detecting an area where a counterfeit product is distributed.

Also, when the authentication server 100 assigns the client key to the first client 200, the processing method in the first client 200 according to the situation may vary. If there is no client key stored in the first client 200, the first client 200 internally stores the new client key received from the authentication server 100.

On the other hand, when the first client 200 captures an activation code of a new article and requests a confirmation, the authentication server 100 generates a new client key corresponding to the new activation code and provides the new client key to the first client 200 can do. Since the client key is matched to the activation code and the specific client device, if the article for which activation is requested is changed, the activation code is changed and the client key also changes. That is, if a client key is already assigned to the first client 200 by acquiring the identification mark of another article in the first client 200, it should be determined for the processing of the previously stored client key.

In one embodiment, the first client 200 internally stores a client key matched to each activation code as it acquires an activation code attached to each article. Accordingly, when the first client 200 makes a request for activation of an article that has been requested for activation, the first client 200 can inform that the client key and the activation code are 'genuine' according to the matching of the client key and the activation code.

For this, the first client 200 can determine whether the client key is matched. For example, the authentication server 100 receives the activation code obtained by the first client 200, and transmits the reference client key 30 matched with the activation code to the first client key. The first client 200 checks whether the same key as the reference client key 30 is present. If the first client 200 includes a key corresponding to the reference client key 30 in the first client 200, the first client 200 can be informed that it is 'genuine'. If the matching key is not included in the first client 200, can do.

In another embodiment, the first client 200 deletes the existing client key and internally stores the new client key. That is, the first client 200 changes an existing client key to a new client key. Even if the client key of the first client 200 is changed, the activation code is identical when the activation code of the previously purchased article is photographed, so that it can be displayed as the first authenticated product on the first client 200 . Since the user of the first client 200 purchases the genuine product and performs the initial authentication, the user of the first client 200 recognizes that it is displayed as a pre-authenticated product, and may not judge that it is a problem.

In addition, the method for detecting a fake article according to an embodiment of the present invention further includes a step of generating the activation code 10 with a random key.

Generally, the code that is given to an item is created based on a specific production rule. Therefore, if the manufacturer of the counterfeit product knows the rule for generating the code, it is possible to generate the same code as the original in the counterfeit or to generate the following code according to the generation rule, and generate the code having the same generation rule as the original And the counterfeit goods attached to it can be distributed to the market.

For example, if it is confirmed that the product conforms to the rule for issuing the activation code 10 obtained by the client, the counterfeit manufacturer may hack the activation code 10 by issuing the activation code 10, If you continue to generate a satisfactory key, you will not be able to verify that it is a counterfeit by using the client key. Therefore, in order to prevent such a problem from occurring, a method of generating the activation code 10 having no generation rule or pattern is provided.

In one embodiment, as shown in FIG. 4, a method of detecting a counterfeit product according to an embodiment of the present invention includes: (S100) a step of generating a random key of a specific digit by the authentication server 100; Confirming whether the random key is already alive and matched to a specific article (S200); If the random key corresponds to a newly generated key, matching the random key with a new product and assigning the random key to the activation code (S300); And re-executing the random key generation if the random key corresponds to the already generated key (S400).

The authentication server 100 generates a random key having a specific number of digits (S100). The random key can have a certain number of digits, and various methods can be applied to the random key generation method. For example, if the rank key is an N-digit number, a random generator is applied to each digit, so that the digits of each digit can be applied separately at random key generation time. If a specific number of digits is generated based on a random generator program, a specific random generator program for each digit may be applied since a specific generation rule by the logic of the random generator can be found.

The authentication server 100 confirms whether the random key has already been generated and matched with a specific article (S200). That is, when the same random key is assigned to a plurality of articles, a genuine article can be judged to be a counterfeit article, so that the authentication server 100 generates a random key without a specific generation rule, It is necessary to judge whether or not it corresponds to "

If the authentication server 100 corresponds to the newly generated key, the random key is matched to the new product and given as the activation code (S300). The granted activation code may be implemented in the form of various identification tags that may be provided to the user. For example, a random key determined with an activation code corresponding to a particular article may be generated by a bar code, a QR code, etc. and provided on the surface of the article (e.g., on the packaging surface of a cosmetic pack) For example, a quality certificate).

When the authentication server 100 corresponds to the key in which the random key is already generated, the random key generation is re-executed (S400). That is, the authentication server 100 can repeatedly perform the random key generation to generate a random key that is not duplicated with the activation code already generated.

In this way, different activation codes can be assigned to each individual article even if they are the same article, so that it can be confirmed whether or not the individual article is a genuine article.

The authentication server 100 can perform the activation process by receiving data corresponding to a specific identification mark or identification mark (for example, numeric data of a specific digit generated by QR) from a user client (i.e., terminal) . That is, the authentication server 100 can match the activation code with a specific article and store it. When receiving the identification tag or the corresponding data from the client, the authentication server 100 can confirm whether or not the activation code is the activation code stored in the authentication server 100 have. The authentication server 100 can inform the user client that it is a genuine product if the value is generated and given as the activation code. If the value is not stored, the authentication server 100 can determine that it is a counterfeit product and guide the user client.

Further, the identification mark provided in the article may include a code corresponding to the article information and an activation code assigned to the article. Therefore, when the authentication server 100 receives the data on the identification mark from the user client, the authentication server 100 can extract the code corresponding to the product information (i.e., the product information code) and the activation code. Thereafter, the authentication server 100 can determine whether or not the product information code and the product activation code extracted from the identification mark match the product activation information of the specific product matched with the activation code stored in the authentication server 100 . Through this, the authentication server 100 can find a case where it is likely to be a counterfeit product because it does not match the product or the matching relation with the article, which corresponds to the code generated by the activation code.

In addition, the authentication server 100 can separately generate an activation code for each vendor or product. As a result, the business ID code or the goods information code can be included together in the identification mark.

Also, the authentication server 100 can determine the revocation period of a specific activation code based on the expiration date, the life cycle, etc. of a specific article. That is, if the expiration date has passed or the normal life cycle has elapsed, there may be a product that disposes of the product without using it. The activation code for such an item may be discarded after the expiration of the period and processed with a code that can be assigned to another new article.

As described above, the method for detecting a fake product based on a client key according to an embodiment of the present invention may be implemented as a program (or an application) to be executed in combination with a hardware computer and stored in a medium.

The above-described program may be stored in a computer-readable medium such as C, C ++, JAVA, machine language, or the like that can be read by the processor (CPU) of the computer through the device interface of the computer, And may include a code encoded in a computer language of the computer.
