ADVANTAGEOUS EFFECTS OF INVENTION

According to the embodiment of the present invention, since the genuine product authentication code is inserted in the genuine product authentication tag in the watermark form (i.e., invisibly), even if the genuine product authentication tag is copied by a third party, the genuine product authentication code having the watermark form cannot be easily extracted, and thus, it is possible to prevent a malicious third party from performing genuine product registration with respect to a target product.

Further, by forming a scratch layer in a partial area of the watermark content in the genuine product authentication label, it is possible to allow a user who actually purchases only the target product to perform genuine product registration for the target product. Further, since it is necessary to separately input an authentication key at the time of genuine product registration, authentication according to the genuine product registration program can be strengthened.

Further, by forming the scratch layer on the genuine product authentication label so as to cover the authentication key printed in the area other than the printed area of the watermark content, it is possible for the user to confirm in advance whether or not the genuine product registration is performed for the corresponding product before purchasing the product. Furthermore, the input of the authentication key is divided into a plurality of times, so that the act of inputting other authentication keys for Cracking (hacking) in order to arbitrarily perform the counterfeit processing on the target product can be prevented.

In the present specification, the phrase "at least two data or information are related to" means that if one data (or information) is obtained, at least a part of the other data (or information) can be obtained based on the obtained data (or information).

In addition, it will be understood that although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention.

Referring to fig. 1, a genuine product authentication system 100 includes a genuine product authentication tag 102, a user terminal 104, and an authentication server 106. Here, the user terminal 104 is communicably connected to the authentication server 106 through the communication network 150. In some embodiments, the communication network 150 may include the internet, at least one local area network (local area networks), wide area networks (wire area networks), cellular networks, mobile networks, other different types of networks, or combinations thereof.

The genuine authentication label 102 may be attached to the target product 10. The target product 10 is a product used as a genuine product authentication object, and examples thereof may include various products such as cosmetics, bags, documents, purses, watches, wines, jewelry, home appliances, communication devices, bicycles, shoes, computer programs, and the like. The genuine article authentication label 102 may be formed to have a sticker form detachable from the target product 10. The genuine product authentication label 102 may be attached to the target product 10 itself or may be attached to a package for packaging the target product 10. The genuine authentication label 102 may be inserted with a genuine authentication code in the form of a watermark. The genuine authentication code may be generated in correspondence with a product identification code (e.g., a product serial number, etc.) of the target product 10.

Fig. 2 is a diagram showing a first embodiment of the genuine product authentication label 102 according to the present invention. Part (a) of fig. 2 is a drawing showing the genuine product authentication label 102 before the scratch layer 125 is peeled off, and part (b) of fig. 2 is a drawing showing the genuine product authentication label 102 after the scratch layer 125 is peeled off.

Referring to fig. 2, the genuine authentication label 102 may include a base member 121, watermark content 123, and a scratch layer 125.

The base member 121 can be used to support the genuine article authentication label 102. Various printable materials such as paper or plastic (vinyl, film, etc.) can be used for the base member 121. A release film may be adhered to the lower surface of the base member 121. After the release film is removed, the genuine authentication label 102 may be attached to the target product 10.

The watermark content 123 may be printed on top of the base part 121. The watermark content 123 may be formed by invisibly inserting a watermark signal generated based on a genuine authentication code to predetermined content. Here, the content may be text or an image (e.g., a still image) or a combination of text and an image. In an exemplary embodiment, the content may use a logo or trademark of a manufacturing company or a selling company of the target product 10.

The watermark content 123 may include a plurality of correction patterns 123 a. The correction patterns 123a may be formed at each corner portion of the watermark content 123. The correction pattern 123a may include two types of correction patterns 123a-1 and 123a-2 having different patterns. In an exemplary embodiment, the correction pattern 123a may include three first correction patterns 123a-1 and one second correction pattern 123 a-2. Three first correction patterns 123a-1 and one second correction pattern 123a-2 may be formed at four corners of the watermark content 123, respectively.

The correction pattern 123a may be used to modify a distorted image of the genuine article authentication label 102, which is obtained when the genuine article authentication label 102 is scanned or photographed by the user terminal 104, due to the posture and angle of the user terminal 104 at the time of scanning or photographing, the degree of bending of the target product 10 to which the genuine article authentication label 102 is attached, and the like, into an original state.

The scratch layer 125 may be formed on a portion of the watermark content 123. In the exemplary embodiment, the scratch layer 125 is formed on at least one of the correction patterns 123a such that the corresponding correction pattern 123a is not visually seen. The scratch layer 125 may be formed to cover the authentication key K printed on the genuine product authentication label 102 (i.e., to make the authentication key K invisible visually). For the purpose of genuine authentication of the target product 10, the authentication key K may be formed in correspondence with the genuine authentication code.

As described above, the genuine product authentication label 102 may have a form in which the genuine product authentication code can be extracted from the watermark content 123 only by peeling the scratch layer 125 by forming the scratch layer 125 in a partial area of the watermark content 123. Thus, only the user who actually purchases the target product 10 can perform genuine registration for the target product 10.

Referring again to fig. 1, the user terminal 104 can obtain an image of the genuine product authentication tag 102 by scanning or photographing the genuine product authentication tag 102 attached to the target product 10. At this time, after the scratch layer 125 is peeled off from the genuine article authentication label 102, the user can scan or photograph the genuine article authentication label 102. When the scratch layer 125 is peeled off, the correction pattern 123a and the authentication key K masked by the scratch layer 125 become visible. As described above, the image of the genuine product authentication tag 102 obtained due to the posture and angle of the user terminal 104 at the time of scanning or photographing, the degree of bending of the target product 10 to which the genuine product authentication tag 102 is attached, and the like is distorted.

The user terminal 104 may modify the image of the genuine product authentication tag 102 into an original state based on the plurality of correction patterns 123a included in the image of the genuine product authentication tag 102. That is, the user terminal 104 may modify the image of the genuine product authentication tag 102 to the original state by extracting three first correction patterns 123a-1 and one second correction pattern 123a-2 from the image of the genuine product authentication tag 102 and then using the positional relationship, distance, angle, and the like between the three first correction patterns 123a-1 and the one second correction pattern 123 a-2. As described above, only by modifying the image of the genuine authentication tag 102 to the original, the watermark signal can be correctly detected from the image of the genuine authentication tag 102.

After detecting the watermark signal from the watermark content 123 in the image of the genuine authentication tag 102, the user terminal 104 may also extract the genuine authentication code from the detected watermark signal. The user terminal 104 may send an authentic authentication request including an authentic authentication code to the authentication server 106. The user terminal 104 may include the location information of the user terminal 104 in the genuine authentication request. The user terminal 104 may receive a result according to the genuine authentication request (hereinafter, may be referred to as a genuine authentication result) from the authentication server 106.

The user terminal 104 may send the authentication key K to the authentication server 106 according to an authentication key request of the authentication server 106. At this time, the user terminal 104 may receive the authentication key K from the user and transmit the authentication key K to the authentication server 106, or may recognize the authentication key K on the image of the genuine authentication tag 102 and transmit the authentication key K to the authentication server 106. However, the present invention is not limited to this, and the user terminal 104 may transmit the authentication key K included in the genuine authentication request.

The user terminal 104 may be loaded with an application (hereinafter, may be referred to as a genuine product authentication application) that performs various functions for genuine product authentication of the target product 10, such as scanning or photographing the genuine product authentication tag 102, modifying the image of the genuine product authentication tag 102, extracting a genuine product authentication code from the image of the genuine product authentication tag 102, and transmitting a genuine product authentication request to the authentication server 106. The genuine authentication application may be stored on a computer-readable storage medium provided in the user terminal 104. The genuine authentication application comprises a set of instructions executable by a processor of the user terminal 104. The instructions may cause a processor of user terminal 104 to perform actions according to the illustrative embodiments. The computer-readable storage media includes components of an operating system for executing a set of instructions, such as a genuine authentication application, on the user terminal 104. For example, the operating system may be iOS from Apple (Apple) or Android from Google (Google).

The authentication server 106 receives a genuine authentication request from the user terminal 104. The authentication server 106 can confirm whether or not the genuine registration is performed for the corresponding target product 10 based on the genuine authentication code included in the genuine authentication request. If the genuine registration has been performed for the comparable target product 10, the authentication server 106 may transmit a genuine authentication result regarding the contents for which the genuine registration has been performed for the comparable target product 10 to the user terminal 104. The authentication server 106 may send an authentication key request to the user terminal 104 if genuine registration is not performed. When the authentication key K received from the user terminal 104 is an authentication key matching the genuine authentication code, the authentication server 106 may perform genuine registration for the target product 10 (i.e., for the product identification code corresponding to the genuine authentication code), and transmit the result to the user terminal 104.

When the authentication key K received from the user terminal 104 is not an authentication key matching the genuine authentication code, the authentication server 106 may retransmit the authentication key request to the user terminal 104. When the number of authentication key requests to the corresponding user terminal 104 exceeds a predetermined number, the authentication server 106 may perform a counterfeit process for the corresponding target product 10 and transmit the result to the user terminal 104.

According to the embodiment of the present invention, since the genuine product authentication code is inserted in the genuine product authentication tag 102 in the form of the watermark (i.e., invisibly), even if the third party copies the genuine product authentication tag 102, the genuine product authentication code having the watermark form cannot be easily extracted, and thus, it is possible to prevent the genuine product registration of the target product 10 by a malicious third party.

Further, by forming the scratch layer 125 in a partial area of the watermark content 123 in the genuine product authentication label 102, it is possible to allow only the user who actually purchases the target product 10 to perform genuine product registration for the target product 10. Further, since it is necessary to separately input an authentication key at the time of genuine product registration, authentication according to the genuine product registration program can be strengthened.

Fig. 3 is a diagram showing a second embodiment of the genuine product authentication label 102 according to the present invention. Part (a) of fig. 3 is a drawing showing the genuine product authentication label 102 before the scratch layer 125 is peeled off, and part (b) of fig. 3 is a drawing showing the genuine product authentication label 102 after the scratch layer 125 is peeled off. Here, description will be made mainly on a portion different from the genuine product authentication tag 102 shown in fig. 2.

Referring to fig. 3, in the genuine authentication label 102, the scratch layer 125 may be formed in a print area of the authentication key K. Specifically, the scratch layer 125 may be formed to cover the authentication key K printed in an area other than the printed area of the watermark content 123 in the genuine authentication label 102. In this case, since the entire watermark content 123 is completely exposed, the genuine authentication code can be extracted by scanning or photographing the genuine authentication label 102 without peeling the scratch layer 125. However, unless the scratch layer 125 is peeled off, the authentication key K cannot be obtained, and thus genuine registration cannot be performed.

Specifically, the user terminal 104 can scan or photograph the genuine article authentication tag 102, extract a genuine article authentication code from an image of the genuine article authentication tag 102, and transmit a genuine article authentication request to the authentication server 106. The authentication server 106 confirms whether or not genuine registration has been performed for the corresponding object product 10 based on the genuine authentication code included in the genuine authentication request, and if genuine registration has been performed, may transmit a result that genuine registration has been performed for the corresponding object product 10 to the user terminal 104.

As described above, the user can confirm whether or not the target product 10 is a product that has been subjected to genuine registration by scanning or photographing the genuine product authentication label 102 before purchasing the target product 10. If the target product 10 is a product that has been registered as a genuine product, the product to be purchased by the user is likely to be a counterfeit, and thus the purchase of the counterfeit can be prevented in advance.

In contrast, if genuine registration is not performed, the authentication server 106 may transmit an authentication key request to the user terminal 104. The user terminal 104 may obtain the authentication key K and transmit the obtained authentication key K to the authentication server 106. That is, when the authentication server 106 transmits the authentication key request, the user determines that the genuine registration is not performed for the corresponding object product 10, and can remove the scratch layer 125 from the genuine authentication label 102 and input the authentication key K to the user terminal 104.

Specifically, if no genuine registration is performed, the authentication server 106 may transmit a first authentication key request to the user terminal 104. The user terminal 104 may send a portion of the authentication key K (e.g., the authentication key K consists of four digits, the first two digits) to the authentication server 106. The authentication server 106 confirms whether or not a part of the authentication key K received from the user terminal 104 and a part of the authentication key matching the genuine authentication code coincide with each other, and if so, may transmit a second authentication key request to the user terminal 104. If a portion of the authentication key K received from the user terminal 104 does not match a portion of the authentication key matching the genuine authentication code, the authentication server 106 may re-transmit the first authentication key request until a portion of the authentication key K received from the user terminal 104 matches a portion of the authentication key matching the genuine authentication code, the number of transmissions being unlimited.

Upon receiving the authentication key request for the second time from the authentication server 106, the user terminal 104 may send the remaining portion of the authentication key K (e.g., the authentication key K is composed of four digits followed by two digits) to the authentication server 106. When the remaining part of the authentication key K received from the user terminal 104 matches the remaining part of the authentication key matching the genuine authentication code, the authentication server 106 may perform genuine registration for the corresponding target product 10 and transmit the result to the user terminal 104.

When the remainder of the authentication key K received from the user terminal 104 does not match the remainder of the authentication key matching the genuine authentication code, the authentication server 106 may resend the second authentication key request to the user terminal 104. When the number of second authentication key requests to the corresponding user terminal 104 exceeds the preset number, the authentication server 106 may perform a counterfeit process for the corresponding target product 10 and transmit the result to the user terminal 104.

According to the embodiment of the present invention, by forming the scratch layer 125 on the genuine article authentication label 102 to cover the authentication key K printed in the area other than the printed area of the watermark content 123, it is possible for the user to confirm in advance whether or not genuine article registration is performed for a corresponding product before purchasing the product. Further, by dividing the input of the authentication key K into a plurality of times, it is possible to prevent the third party from inputting another authentication key for hacking (hacking) in order to arbitrarily perform the counterfeit processing with respect to the target product 10.

Fig. 4 is a flowchart for explaining a genuine authentication method according to the first embodiment of the present invention. For example, the method shown in fig. 4 may be performed by the user terminal 104 and the authentication server 106 described above. The flow chart in the figure shows that the method is divided into a plurality of steps, but at least a part of the steps can be carried out in reverse order, or combined with other steps, or omitted, or divided into detailed steps, or carried out by adding at least one step which is not shown in the figure.

Referring to fig. 4, the user terminal 104 obtains an image of the genuine product authentication tag 102 by scanning or photographing the genuine product authentication tag 102 attached to the target product 10 (S102). After peeling the scratch layer 125 from the genuine article authentication label 102, the user can scan or photograph the genuine article authentication label 102. Here, the scratch layer 125 may be formed in a partial area of the watermark content 123 in the genuine article authentication label 102 so as to cover the authentication key K.

Next, the user terminal 104 modifies the image of the genuine product authentication tag 102 into the original state based on the plurality of correction patterns 123a included in the image of the genuine product authentication tag 102 (S104).

Next, the user terminal 104 extracts a genuine authentication code from the image of the genuine authentication tag 102 (S106). After detecting the watermark signal from the watermark content 123 in the image of the genuine authentication tag 102, the user terminal 104 may also extract the genuine authentication code from the detected watermark signal.

Next, the user terminal 104 transmits a genuine authentication request including a genuine authentication code to the authentication server 106 (S108).

Thereafter, the authentication server 106 confirms whether or not genuine registration is performed for the corresponding target product 10 based on the genuine authentication code included in the genuine authentication request (S110). The authentication server 106 may extract product identification information matching the genuine product authentication code and confirm whether or not the genuine product registration is performed on the extracted product identification information.

As a result of the confirmation at step S110, if the genuine registration has been performed, the authentication server 106 transmits a genuine authentication result on the content for which the genuine registration has been performed with respect to the counterpart target product 10 to the user terminal 104 (S112).

As a result of the confirmation at step S110, if the genuine registration is not performed, the authentication server 106 transmits an authentication key request to the user terminal 104 (S114).

Next, the user terminal 104 obtains the authentication key K printed on the genuine authentication label 102, and transmits the obtained authentication key K to the authentication server 106 (S116).

Then, the authentication server 106 confirms whether or not the authentication key K received from the user terminal 104 matches the authentication key matching the genuine authentication code (S118). The authentication server 106 may extract an authentication key matching the genuine authentication code and confirm whether or not the extracted authentication key matches the authentication key K received from the user terminal 104.

As a result of the confirmation at step S118, if the authentication key K received from the user terminal 104 is identical to the authentication key matching the genuine authentication code, the authentication server 106 performs genuine registration for the corresponding target product 10 and transmits the result thereof to the user terminal 104 (S120).

As a result of the confirmation at step S118, if the authentication key K received from the user terminal 104 does not coincide with the authentication key matching the genuine authentication code, the authentication server 106 retransmits an authentication key request to the user terminal 104 (S122).

Next, the authentication server 106 confirms whether or not the number of authentication key requests exceeds a preset number (S124). As a result of the confirmation in step S124, if the number of times exceeds the predetermined number of times, the authentication server 106 performs the counterfeit processing for the corresponding target product 10 and transmits the result to the user terminal 104 (S126). As a result of the confirmation in step S124, if the number of times exceeds the preset number of times, the authentication server 106 returns to the process in step S118 and repeats the subsequent processes.

Fig. 5 is a flowchart for explaining a genuine authentication method according to the second embodiment of the present invention. For example, the method shown in fig. 5 may be performed by the user terminal 104 and the authentication server 106 described above. The flow chart in the figure shows that the method is divided into a plurality of steps, but at least a part of the steps can be carried out in reverse order, or combined with other steps, or omitted, or divided into detailed steps, or carried out by adding at least one step which is not shown in the figure.

Referring to fig. 5, the user terminal 104 obtains an image of the genuine product authentication tag 102 by scanning or photographing the genuine product authentication tag 102 attached to the target product 10 (S202). Here, the genuine product authentication label 102 may be formed by forming the scratch layer 125 so as to cover the authentication key K printed in an area other than the printed area of the watermark content 123. In this case, the user terminal 104 can obtain an image of the genuine authentication label 102 in which the entire watermark content 123 is completely exposed without peeling the scratch layer 125.

Next, the user terminal 104 modifies the image of the genuine product authentication tag 102 into the original state based on the plurality of correction patterns 123a included in the image of the genuine product authentication tag 102 (S204).

Then, the user terminal 104 extracts the genuine authentication code from the image of the genuine authentication tag 102 (S206), and transmits a genuine authentication request including the extracted genuine authentication code to the authentication server 106 (S208).

Next, the authentication server 106 confirms whether or not genuine registration is performed for the corresponding target product 10 based on the genuine authentication code included in the genuine authentication request (S210).

As a result of the confirmation at step S210, if the genuine registration has been performed, the authentication server 106 transmits a genuine authentication result on the content for which the genuine registration has been performed on the counterpart target product 10 to the user terminal 104 (S212).

As a result of the confirmation at step S210, if the genuine registration is not performed, the authentication server 106 transmits a first authentication key request to the user terminal 104 (S214).

Then, the user terminal 104 transmits a part of the authentication key K printed on the genuine authentication label 102 to the authentication server 106 (S216). For example, when the authentication server 106 transmits a first authentication key request, the user may expose the authentication key K by peeling the scratch layer 125 from the genuine authentication label 102, and input a part of the authentication key K to the user terminal 104. Thus, the user terminal 104 can transmit a part of the input authentication key K to the authentication server 106.

Next, the authentication server 106 confirms whether or not a part of the authentication key K received from the user terminal 104 matches a part of the authentication key matching the genuine authentication code (S218).

As a result of the confirmation in step S218, if a part of the authentication key K received from the user terminal 104 does not coincide with a part of the authentication key matching the genuine authentication code, the first authentication key request may be transmitted again until a part of the authentication key K received from the user terminal 104 coincides with a part of the authentication key matching the genuine authentication code.

As a result of the confirmation in step S218, if a part of the authentication key K received from the user terminal 104 coincides with a part of the authentication key matching the genuine authentication code, the authentication server 106 transmits a second authentication key request to the user terminal 104 (S220).

Next, the user terminal 104 transmits the remaining part of the authentication key K to the authentication server 106 (S222). For example, when the authentication server 106 sends a second authentication key request, the user may enter the remainder of the authentication key K into the user terminal 104. Thus, the user terminal 104 can transmit the remaining part of the input authentication key K to the authentication server 106.

Then, the authentication server 106 confirms whether or not the remaining part of the authentication key K received from the user terminal 104 matches the remaining part of the authentication key matching the genuine authentication code (S224).

As a result of the confirmation in step S224, if the remaining part of the authentication key K received from the user terminal 104 and the remaining part of the authentication key matching the genuine authentication code coincide, the authentication server 106 performs genuine registration for the corresponding target product 10 and transmits the result thereof to the user terminal 104 (S226).

As a result of the confirmation at step S224, if the remaining part of the authentication key K received from the user terminal 104 does not coincide with the remaining part of the authentication key matching the genuine authentication code, the authentication server 106 retransmits a second authentication key request to the user terminal 104 (S228).

Next, the authentication server 106 checks whether the number of second authentication key requests exceeds a preset number (S230). As a result of the confirmation in step S230, if the number of times exceeds the predetermined number of times, the authentication server 106 performs the counterfeit processing for the corresponding target product 10 and transmits the result to the user terminal 104 (S232). As a result of the confirmation in step S230, if the number of times exceeds the preset number of times, the authentication server 106 returns to the process in step S224, and repeats the subsequent processes.

Referring to fig. 6, a genuine article authentication label manufacturing system 200 may include a registration server 202 and a label manufacturing apparatus 204. Here, the registration server 202 is communicably connected to the label producing apparatus 204 via the communication network 250. In some embodiments, communication network 250 may include the Internet, at least one local area network (local area networks), wide area networks (wire area networks), cellular networks, mobile networks, other different types of networks, or combinations thereof.

The registration server 202 may generate watermarked content according to the respective target product 10 (i.e. according to the respective product identification code). The registration server 202 may send the generated individual watermark content to the label producing device 204. The registration server 202 may include an authentication-related information generation module 211, a watermark content generation module 213, and a storage module 215.

The authentication-related information generation module 211 may assign a genuine authentication code based on the product-related information. Here, the product-related information may include a type of the product, the number of the products, a product identification code of each product, and the like. For example, the authentication-related information generation module 211 may generate different genuine authentication codes according to the number of products, and match the unique genuine authentication code with each product identification code. That is, in the present invention, each target product 10 is given a unique genuine product authentication code, so that a genuine product or a counterfeit product can be confirmed from each target product 10. The authentication-related information generation module 211 may generate different authentication keys according to the respective genuine authentication codes, and match the unique authentication key with the respective genuine authentication codes.

The watermark content generation module 213 may generate watermark content by inserting individual genuine authentication codes into the content. Specifically, the watermark content generation module 213 may receive the genuine authentication code from the authentication-related information generation module 211 and generate the watermark signal based on the received genuine authentication code. For example, after Message Encoding (Message Encoding) the received genuine authentication code, the watermark content generating module 213 may generate an autocorrelation Sequence (Auto Correlation Sequence) by using the Message-encoded genuine authentication code as a Seed (Seed) value and randomize the autocorrelation Sequence, and then expand the randomized autocorrelation Sequence to the same size as the content to generate a watermark signal.

The watermark content generating module 213 may generate watermark content by inserting the generated watermark signal to content (e.g., a logo image of a manufacturing company of the target product 10) at a preset insertion strength. The watermark content generation module 213 may generate a correction pattern (for example, the correction pattern 123a shown in fig. 2) and insert the generated correction pattern into the watermark content.

The storage module 215 may match and store each product identification code with its corresponding genuine authentication code. The storage module 215 may match and store each genuine authentication code with an authentication key corresponding thereto. That is, the storage module 215 may match and store each product identification code and the genuine authentication code and the authentication key corresponding thereto with each other. The storage module 215 may match and store each product identification code with its corresponding watermark content. The storage module 215 may share matching information between the product identification code, the genuine authentication code, and the authentication key with the authentication server 106. The registration server 202 and the authentication server 106 may be implemented as separate devices, but are not limited thereto, and may be implemented as an integrated device.

The registration server 202 may send the generated watermark content to the label producing device 204. The registration server 202 may transmit an authentication key matching the genuine authentication code inserted into the corresponding watermark content to the label producing apparatus 204.

The tag manufacturing apparatus 204 can manufacture a genuine authentication tag (for example, the genuine authentication tag 102 shown in fig. 2) based on the watermark content and the authentication key received from the registration server 202. Referring to fig. 2, the label maker 204 may print the watermark content 123 on one side of the base member 121. The label producing apparatus 204 may form the scratch layer 125 in a part of the area of the watermark content 123 (for example, at least one area in the area where the correction pattern 123a is formed). In this case, the label producing apparatus 204 can conceal the authentication key and the at least one correction pattern 123a, which are matched with the genuine authentication code inserted into the corresponding watermark content, simultaneously with the scratch layer 125. The authentication key may be printed in an area other than the area where the watermark content 123 is formed in one surface of the base part 121.

However, the present invention is not limited to this, and the label producing apparatus 204 may print the authentication key on an area other than the area where the watermark content 123 is formed on the one surface of the base member 121, and form the scratch layer 125 only on the authentication key portion.

In addition, it is described herein that the tag manufacturing apparatus 204 receives the watermark content from the registration server 202, but the present invention is not limited thereto, and the watermark content may be generated by the tag manufacturing apparatus 204. That is, the watermark content generating module 213 may be included in the label producing apparatus 204.

Referring to fig. 7, the watermark content generating module 213 may include a watermark signal generating unit 221, a video normalizing unit 223, an insertion strength determining unit 225, a watermark signal inserting unit 227, and a correction pattern generating unit 229.

The watermark signal generating unit 221 may generate a watermark signal to be inserted into the content by receiving the genuine authentication code. Specifically, after generating an Error correction Code (Error Correct Code) for the genuine authentication Code, the watermark signal generation unit 221 may generate a Regular Code (Regular Code) by randomizing the genuine authentication Code and the Error correction Code.

As described above, the reason why the regular code is generated by randomizing the additional information and the Error correction code is to increase the detection rate when detecting the genuine authentication code inserted to the watermark content by replacing a Burst Error (Random Error) that may be generated when the user terminal 104 obtains the watermark content using a camera with a Random Error (Random Error). That is, by dispersing the genuine authentication code and the error correction code at random to prevent the error from concentrating on one part, the detection rate of the genuine authentication code can be improved in the process of detecting the genuine authentication code inserted into the watermark content. In other words, the user terminal 104 that detects the watermark signal is more robust against random errors among burst errors and random errors, and therefore, the detection rate of the genuine authentication code is higher in the case of not burst errors but random errors. Thus, by generating the normal code by randomizing the genuine authentication code and the error correction code, the burst error is replaced with the random error, so that the detection rate of the genuine authentication code can be improved in the user terminal 104.

The watermark signal generation unit 221 may generate an autocorrelation sequence by using a regular code as a Seed (Seed) value. Here, the autocorrelation sequence refers to a signal in which the coefficient values are randomly arranged according to the seed value 1 or-1, and the total composition of the entire coefficients becomes 0. The watermark signal generation unit 221 may generate an autocorrelation sequence in which the degree of similarity between sequences generated with the same seed is 1 and the degree of similarity between sequences generated with different seeds is 0.

The watermark signal generation unit 221 may generate a watermark signal by randomizing the position in the content where the autocorrelation sequence is to be inserted two-dimensionally (2D), and expanding the size of the autocorrelation sequence two-dimensionally (2D) to the same size as the normalized size of the content. The watermark signal generation unit 221 randomizes the position in the content where the autocorrelation sequence is to be inserted, thereby being able to minimize the Burst Error (Burst Error) described above. That is, in the embodiment of the present invention, it is possible to minimize burst errors that may occur when the user terminal 104 obtains watermark content using a camera by randomizing a genuine authentication code and an error correction code to generate a regular code and randomizing a position in the content where an autocorrelation sequence is to be inserted.

The watermark signal generation unit 221 may two-dimensionally expand the randomized autocorrelation sequence by n × n times. For example, if the normalized size of the content is 320 × 320 (horizontal × vertical) (the unit may be pixels), and the size of the randomized autocorrelation sequence is 160 × 160, the watermark signal generation unit 221 may make the randomized autocorrelation sequence have a size of 320 × 320 by expanding it two-dimensionally by 2 × 2. As described above, the reason why the watermark signal is generated by expanding the randomized autocorrelation sequence by n × n times is to easily obtain the watermark content regardless of the resolution of the camera and the distance between the camera and the watermark content when the user terminal 104 obtains the watermark content using the camera or the like.

If the input content is video content (for example, if the content is a logo image of a manufacturing company or a sales company of the target product 10), the video normalization unit 223 may normalize the video content to a preset size (M × N). Here, the reason why the video content is normalized to the predetermined size is to synchronize the obtained watermark content when the watermark content is obtained by a camera or the like at the user terminal 104, thereby correctly detecting a genuine authentication code from the obtained watermark content. The video normalization unit 223 may normalize the video content to a square (M × M).

After confirming the aspect ratio of the video content, the video normalization unit 223 may perform normalization by scaling the video content in the direction in which the relative proportion is large, as a criterion. For example, in the case of normalizing 160 × 120 (vertical × horizontal) sized video content to 320 × 320, since the relative proportion of the video content in the horizontal direction is large, the video normalization unit 223 performs normalization by scaling the video content with the horizontal direction as a criterion. In this case, the video normalizing unit 223 adjusts the size of the width of the video content to 320 by expanding the video content to 2 × 2 times. Accordingly, the size of the video content becomes 320 × 240, and at this time, a Padding (Padding) method is applied to the vertical direction to generate an image of a portion corresponding to the remainder 80. That is, the vertical direction having a small relative proportion is formed by filling at a boundary value of 320 × 320. At this time, the video normalizing unit 223 may normalize in a state in which the aspect ratio of the input video content is kept unchanged, so that the normalized video content is not distorted compared with the original video content.

The insertion strength decision unit 225 may decide the insertion strength when inserting the watermark signal to the normalized video content.

The watermark signal insertion unit 227 may insert a watermark signal into the normalized video content in accordance with the determined insertion strength.

After generating the correction pattern, correction pattern generation section 229 may insert the generated correction pattern into the video content into which the watermark signal is inserted (i.e., watermark content). At this time, the correction pattern generation unit 229 may generate correction patterns having different patterns (refer to fig. 2, the first correction pattern 123a-1 and the second correction pattern 123 a-2). For example, the correction pattern generation unit 229 may generate three first correction patterns 123a-1 and one second correction pattern 123 a-2. The correction pattern generation unit 229 may insert three first correction patterns 123a-1 and one second correction pattern 123a-2 into each corner (Edge) of the watermark content. Thus, when the user terminal 104 obtains the watermark content by scanning or shooting, the watermark content can be modified to the original state by extracting the correction pattern from the obtained watermark content.

Fig. 8 is a drawing showing a first correction pattern and a second correction pattern according to an embodiment of the present invention. Referring to fig. 8 (a), the first correction pattern 123a-1 includes a 1 st-1 st black pattern 151, a first white pattern 154 formed inside the 1 st-1 st black pattern 151, and a 1 st-2 nd black pattern 157 formed inside the first white pattern 154. The 1 st-1 st black pattern 151, the first white pattern 154, and the 1 st-2 nd black pattern 157 may be formed in a circular shape. In this case, for example, the 1 st-1 st black pattern 151, the first white pattern 154, and the 1 st-2 nd black pattern 157 may have a diameter ratio of 7:5: 3. In this case, the ratio of the black pattern to the white pattern displayed in the center of the first correction pattern 123a-1 in the longitudinal or lateral direction is 1 (black): 1 (white): 3 (black): 1 (white): 1 (black).

Referring to part (b) of fig. 8, the second correction pattern 123a-2 includes a 2 nd-1 st black pattern 161, a second white pattern 164 formed inside the 2 nd-1 st black pattern 161, and a 2 nd-2 nd black pattern 167 formed inside the second white pattern 164. The 2-1 th black pattern 161, the second white pattern 164, and the 2-2 nd black pattern 167 may be formed in a circular shape. In this case, for example, the 2 nd-1 st black pattern 161, the second white pattern 164, and the 2 nd-2 nd black pattern 167 may have a diameter ratio of 7:5: 1. In this case, the ratio of the black pattern to the white pattern displayed in the center of the second correction pattern 123a-2 in the longitudinal or lateral direction is 1 (black): 2 (white): 1 (black). As described above, in the second correction pattern 123a-2, the size of the 2 nd-1 st black pattern 161 may be the same as the size of the 1 st-1 st black pattern 151, and two different correction patterns 123a-1, 123a-2 may be formed by making the sizes of the second white pattern 164 and the 2 nd-2 nd black pattern 167 different from the sizes of the first white pattern 154 and the 1 st-2 nd black pattern 167, respectively. Here, by forming the first correction pattern 123a-1 and the second correction pattern 123a-2 in a circular shape, even if the genuine product authentication label 102 on which the watermark content is printed is attached to any object, it is possible to minimize distortion of the watermark content obtained by a camera or the like at the user terminal 104 and stably detect the first correction pattern 123a-1 and the second correction pattern 123 a-2.

Further, by alternately displaying the black pattern and the white pattern in the first correction pattern 123a-1 and the second correction pattern 123a-2, the difference in brightness can be generated to the maximum, and the first correction pattern 123a-1 and the second correction pattern 123a-2 can be easily detected in the user terminal 104.

The genuine product authentication label 102 may be a label printed with a multidimensional hologram. Here, the watermark content may be printed on the hologram layer of the genuine authentication label 102. Fig. 9 is a drawing schematically showing a label for genuine article authentication according to another embodiment of the present invention. Referring to fig. 9, a hologram layer may be printed on the base member, and watermark content may be printed on the hologram layer. In this case, if an attempt is made to copy the genuine authentication label 102 by an optical device such as a scanner or a copying machine, diffused reflection occurs in the hologram layer of the genuine authentication label 102, so that an image is obtained in a state where the content of the watermark on the hologram layer is deteriorated or damaged, and thus the copying of the genuine authentication label 102 can be prevented. That is, since the hologram layer is pressed with the fine concave-convex pattern, if light emitted from a scanner, a copier, or the like enters the hologram layer, strong diffuse reflection occurs in the hologram layer, and as shown in fig. 10, an image is obtained in a state where watermark content on the hologram layer is deteriorated or damaged, and thus a genuine authentication code cannot be extracted from the watermark content. Therefore, it is possible to prevent a malicious third party from copying the genuine authentication tag 102.

Here, an optical device such as a copying machine or a scanner emits light at its own unique set angle in order to obtain an image. As described above, in view of the fact that the respective optical devices have different light emission angles, the hologram is generated as a multi-shot method (or a multi-dimensional hologram), and then the copy can be prevented by attempting the copy through any other optical device.

The pattern of the predetermined pattern on the genuine product authentication label 102 may be formed in a dot shape. That is, each printer has a predetermined specific pattern at the time of printing output. Here, when printing the genuine product authentication label 102, if a predetermined specific pattern is dot-printed, even if the genuine product authentication label 102 is copied, whether or not the copy is made can be detected by checking the enlarged portion where the specific pattern is formed.

That is, since the printing dot of the printing apparatus (for example, the label manufacturing apparatus 204) that prints the genuine product authentication label 102 is different from the printing dot of the printing apparatus that copies the genuine product authentication label 102, whether or not the genuine product authentication label 102 is copied can be confirmed by comparing the printing dots with each other.

In addition, in the manufacturing process of the genuine product authentication label 102, when the watermark content is printed on the base member, a fine pattern which is not recognizable by a scanner, a copier, or the like may be formed at a specific position matching each genuine product authentication code included in the watermark content. That is, when a malicious third party scans or copies the genuine product authentication label 102, the fine pattern can be prevented from being copied. The coordinate values of the fine pattern may be set to be different for each genuine product authentication code.

The authentication server 106 can discriminate between a genuine product and a counterfeit product by monitoring detection of a plurality of genuine product authentication codes in a specific area or detection of the same genuine product authentication code at the same or similar time in different areas based on the position (i.e., the position of the user terminal 104 that transmitted the genuine product authentication code) at which the genuine product authentication code was detected, the time, and the like. When the genuine product authentication code is collectively detected in the specific area, the authentication server 106 can determine that a duplicate of the genuine product authentication tag 102 is manufactured in the corresponding area. The authentication server 106 can analyze the counterfeit suspicious region (counterfeit manufacturing region) by analyzing the number of times of detection, detection time, and the like of the genuine authentication code from each region.

When the genuine authentication code is obtained from the user terminal 104, the authentication server 106 may extract an additional code that matches the corresponding genuine authentication code and is stored. The additional code may be formed to be mapped to the genuine authentication code by an arbitrary numerical expression. When the additional code is mapped to the genuine authentication code, the authentication server 106 may perform a procedure for genuine registration, and when the additional code is not mapped to the genuine authentication code, the authentication server 106 may perform a procedure for counterfeit processing.

Further, if the genuine product registration is performed for the corresponding target product, the authentication server 106 may transmit distribution-related information (distribution route, distribution time, etc.) of the corresponding target product to the user terminal 104.
