Description

The invention relates to a system for providing services for authenticity evaluation of watches using the QR code, and provides a system that stores and manages information of each user and each watch by associating it with a QR code, by etching a QR code on the back of the watch and creating a watch register.

The impact of counterfeiting of official documents and currencies is significant, so efforts such as technology development to prevent this even with a large budget are actively progressing, and technology is making great progress, but as printing technology advances, the damage to manufacturers and consumers from affixing fake or counterfeit trademarks is also continuously increasing worldwide. Therefore, developing technologies and frameworks that can effectively and cost-effectively detect counterfeit trademarks can lead to increased revenue for manufacturers by removing counterfeit goods from circulation, and for consumers by ensuring that they can purchase goods with confidence, creating economic benefits for both manufacturers and consumers through trustworthy goods.

Methods for authenticity authentication and forgery detection were researched and developed, in this context the prior art, Korean Public Patent No. 2014-0016121 (published on February 7, 2014) and Korean Public Patent No. 2019-0023323 (published on March 8, 2019) each discloses that when the server receives an authentication request from a business terminal, it searches the database to verify authenticity, re-registers the requested commodity, generates a QR code after encoding the authenticity verification and the newly registered authentication request with the web link and sends it to the business terminal, prints the QR code on the business terminal and attaches it to the authentication card, and checks whether the QR code is fake or not by extracting the authenticity authentication history from the QR code based on the authenticity authentication information of the QR code requested for authenticity authentication to detect fakeness and comparing it with the pre-stored authenticity authentication history.

However, in the former case, when the store requests the certification, the QR code is generated, and the store receives it and prints it on a printer, so if each store uses a different printer or different label paper, there is no way to distinguish it even if a counterfeiter prints the same QR code. Even in the latter case, although the certification history stored on the server and the certification history of the QR code are compared, if the QR code itself is counterfeit, it is impossible to know whether it is an authenticity authentication history or an authentication history of counterfeit products. Since the QR code of the counterfeit products is still stored on the server even when it requests authentication, it may be possible to store only the distribution route of the counterfeit products. Therefore, research and development of a system for accurately verifying the authenticity of products using the QR code is necessary.

An embodiment of the present invention provides a basic framework for authenticity authentication that enables effective detection of counterfeits while minimizing the additional cost of manufacturing the product by etching a QR code on the back of a product, allowing the authenticity of the product to be checked on a user terminal through an application, and allowing users who have sold or purchased products to manage whether they own the products or not, such as a vehicle registrar, and in particular, provides a system for providing services for authenticity assessment of the watches using the QR code, which is capable of authenticity assessment without hiring a specialist for authenticity assessment of the watches. However, the technical objects of the present embodiments are not limited to those described above, and other technical objects may also exist.

As a technical means for solving the above-described technical problem, an embodiment of the present invention is a manufacturer server that uploads the QR code after etching the QR code on the back of the watch, a user terminal that receives and thus prints out the result of authenticity evaluation by picking up or scanning the QR code on the back of the watch, and an authenticity evaluation service provider server that includes a registration unit that receives and registers the QR code etched on the back of the watch from the manufacturer server, an authenticity evaluation unit that checks whether the QR code registered on the manufacturer server matches the picked up or scanned QR code when the QR code is captured or scanned on a user terminal, and a result transmission unit that transmits the result of the authenticity verification to the user terminal when the QR code registered on the manufacturer server matches the captured or scanned QR code.

2 is a block diagram illustrating the 1 included service provider server for authenticity assessment, and 3 and 4 are diagrams for explaining an embodiment in which the watch authenticity evaluation services are implemented using a QR code according to an embodiment of the present invention.

With reference to 2 the authenticity evaluation service provider server 300 may include a registration unit 310, an authenticity evaluation unit 320, a result transmission unit 330, a register creation unit 340, an ownership transfer recording unit 350, a specification storage unit 360, a forgery checking unit 370, an anti-forgery unit 380, a forgery destruction unit 390, a forgery tracking unit 391, and a document checking unit 393.

In addition, the service program may be operated on the at least one user terminal 100 and the at least one manufacturer server 400 using a script executed on a web browser. Here, a web browser is a program that enables the use of web service (WWW: World Wide Web), means a program that accepts and displays hypertexts described in HTML (Hyper Text Markup Language) and includes, for example, Netscape, Explorer and Chrome, etc. In addition, an application means an application program on a terminal device and includes, for example, an app that runs on a mobile device (smartphone).

With reference to 2 the registration unit 310 can receive and register a QR code etched on the back of the watch from the manufacturer server 400. The manufacturer server 400 can upload the QR code after etching the QR code on the back of the watch. In this case, a laser can be used for etching, and different methods can be adopted depending on the material of the watch. Laser marking is a method of printing a logo, product name, serial number, model number, and the like by melting, burning, peeling, oxidizing, cutting, and discoloring the surface by irradiating laser light on a target object, and is roughly divided into two types: mask type and scanning type. In this case, color development is largely divided into foaming, condensation, carbonization, and chemical change, and CO2 laser, YVO4 laser, YAG laser, and the like can be selected according to the material and processing method of the target object. Processing methods suitable for the material of the back of the watch can be used, and various laser marking machines are available. [Table 1] editing material melt resin burn Paper . Resin peel plated metal -printed paper oxidize metal cut Glass - Metal - Resin decolorize resin

When the bullet is fired from the gun, it leaves a unique spin on the bullet which acts as a fingerprint for the gun and is used to identify the gun owner. In the case of a printing machine, such as a printer, there is a method of specifying a printing machine depending on what type of paper is used and what type of printer is used. Also, laser marking is a high speed, non-contact technology that creates a permanent mark on a metal or plastic surface, where the marking is done by permanently changing the contrast of a specific area of a surface using a focused wavelength of light known as laser light, and where there are a number of variables such as laser settings e.g. wavelength, material (or substrate), marking type, speed, pulse frequency, power, etc., and depending on this, the QR code generated by laser marking varies. The manufacturer combines and selects the laser type, material type, marking type, laser setting, and the like. This variable can be used as information to determine authenticity if a counterfeit with the etched QR code is later found using this variable.

<Security QR Code->

The security QR code functions by recognizing the QR code with a regular smartphone camera to retrieve information and to prevent its use for other purposes, wherein in the authenticity evaluation service provider server 300 according to an embodiment of the present invention, the circular QR code information generated by random numbers is first converted using the symmetric AES crypto algorithm. Thereafter, the converted data may be secondarily encrypted using the private key of the RSA public key encryption algorithm, and finally a QR code composed of binary values may be generated. In the application of the user terminal 100, after recognizing the binary QR code, decryption may be performed using the public key of the RSA public key algorithm loaded in the application, and then an authentication request may be made to the authenticity evaluation service provider server 300. From the converted QR code data requested to the authenticity evaluation service provider server 300, the circular QR code information can be obtained using the AES symmetric key. When generating a security QR code, it is possible to distinguish between a genuine application and a fake application without public keys using the RSA public key encryption algorithm, the printed binary QR code does not have the circular QR code information exposed by a general camera, and even if the public key of the application is exposed or the value decrypted with the public key is found, the circular value of the QR code cannot be recognized because it is a modified QR code value. In this way, administrators can quickly check and determine whether a product is genuine or fake by comparison even if it has been tampered with.

< Authentication Application>

The authenticity authentication application provides both security authentication services and management services, and has a QR code scanning function and an administrator mode. The protected QR code can be decrypted with the public key of the RSA public key algorithm only through the camera function installed in the activation application. In addition, a page can be displayed when a genuine QR code is recognized by the authenticity authentication application, and the number of authenticity authentications of the corresponding QR code performed can be displayed in numbers. The administrator mode can include a QR code generation function, a search function by QR code number and product name, a detailed view, and a function for displaying the location where QR code authentication is requested on a map.

When a QR code is generated, it is stored in the database in the form of a character string and automatically updated in the administrator mode list. Administrator can delete QR codes for products suspected of duplicate QR codes or that are no longer handled. User's location information collected during authentication is also displayed, and by categorizing colors according to the number of queries, QR codes that have exceeded the predetermined threshold can be easily detected. QR code duplicate detection is performed when the same QR code is authenticated at a similar time in a remote location, and when the same QR code is authenticated with different smartphones using a disposable QR code, a method for notifying administrators and users can be used.

< Authentication/Distribution Tracking>

The QR code authentication program can use the AWS cloud server EC2 and use the MySQL database.

It can be equipped with the symmetric key algorithm AES and the public key algorithm RSA, as well as a database used for the security of QR codes. The data transmission method between the server and the client can be sent and received in a POST method without exposing data and without limiting the transmission length. After comparing the transmitted data with the data in the database, the authenticity authentication page can be issued.

When a QR code is picked up or scanned by the user terminal 100, the authenticity evaluation unit 320 may check whether the picked up or scanned QR code and the QR code registered on the manufacturer server 400 match. The user terminal 100 may receive and output the result of authenticity evaluation by picking up or scanning the QR code on the back of the watches.

The result transmission unit 330 may transmit an authenticity verification result to the user terminal 100 when the QR code registered on the manufacturer server 400 and the captured or scanned QR code match.

When a purchase is made on the user terminal 100, the register creation unit 340 may create a watch register that includes the user name of the user terminal 100, the user address, the name of the issuing manufacturer, the first registration date of the watch, the unique identification number of the watch, the model name of the watch, the usage period, the QR code, the name of at least one component of the watch, the size of the watch, the gross weight of the watch, the ex-factory price of the watch, the purchase route, and the receipt. Just as there is a vehicle settings register in every car, in an embodiment of the present invention, a watch register is created based on the first registered user, and in the event of a transfer of ownership, it may be created in a format similar to the real estate registers so that the owner is still described. The transaction data (content of the transfer of ownership contract) of the watch register thus created can be created and stored for each owner in each block of the blockchain.

The reason for chaining the transaction data in each block, rather than the watch register itself, is to catch two buyers authenticating with a fake QR code at the same time or at different times, such as in a double sale of a property. When two buyers authenticate, one seller (user) becomes two buyers, and the blocks connected in series suddenly branch into two. This is to prevent two or more different watch registers from being created and circulated for a single watch. This is to prevent the occurrence of branching itself by monitoring and detecting the occurrence of branching into two, and to prevent two or more different watch registers from being created and circulated in one watch. Because if the reliability of the watch register itself is no longer guaranteed, the QR code of the present invention will also have no meaning for authenticating products. Of course, the authenticity evaluation service provider server 300 and the manufacturer server 400 of the present invention may also manage the watch register to identify the true buyer, but if two buyers, i.e., a true buyer and a fraudulent buyer, claim to be the true buyer at the same time or at different times, there is a possibility that two watch registers, i.e., watch registers with different buyers, are in circulation, and a well-meaning third party who believes them will suffer a loss such as purchasing a fake watch at a genuine price based on the watch register alone.

The ownership transfer recording unit 350 creates a watch register based on the user of the user terminal 100 when the user terminal 100 registers the watch for the first time after authenticating the watch, and can record a transaction between the user terminal 100 and the purchasing terminal by creating and linking a new block in the blockchain when the ownership is transferred from the user terminal 100 to the purchasing terminal.

When a QR code is uploaded to the manufacturer server 400, the specification storage unit 360 can receive and store the specification data including etching data, specific data including photo data of the QR code, and etching data including QR code size, etching width, etching length, and etching depth.

When the QR code is picked up by the user terminal 100, the counterfeit checking unit 370 can recognize the features of the image and then compare them to analyze the identity between the image of the QR code and the image in the specification data, and determine whether it is the same QR code or not. Here, it is assumed that the counterfeit QR code replicates the genuine QR code using a high-quality scanner. It is assumed that the color information designed with the RGB color model via the scanner is based on the RGB color model on designed on the PC and then converted into a vector file for laser etching during the actual printing process, which can lead to distortions.

< Preprocessing of QR code images >

For image preprocessing, the anti-counterfeiting unit 370 receives the image including the QR code captured by the user terminal 100 using the application, and first converts it into a luminance signal (GrayScale), and then extracts the black and white information to detect the QR code. After receiving the image including the QR code captured by the user terminal 100 using the application, the anti-counterfeiting unit 370 first converts it into a luminance signal (GrayScale), and then extracts black and white information to detect the QR code. In the process, if the QR code is not detected or the image is not captured accurately, the anti-counterfeiting unit 370 may request the user terminal 100 to capture the image again. If the QR code is detected, image cropping for the QR code part is performed based on the center point of the Finder Pattern present in the QR code. The image of the cut-off QR code part is distorted into an image of size M×M. Based on the color image processed in the preprocessing block, it can be determined whether the product is genuine or fake based on a convolutional neural network algorithm for authentication.

Since the illuminance of the image varies depending on the location, the user's location, the time, and the performance of the smartphone, the histogram matching, the spatial matching with the genuine QR code stored in the anti-counterfeiting unit 370 are first performed.

VGGNet learns different types of real QR codes and fake QR codes in advance. A real QR code or a fake QR code can be determined by using a learned convolutional neural network, which uses a typical VGGNet structure among the convolutional neural networks.

Here, after adjusting the size of the input image to 224×224, VGGNet can be composed of a total of 16 layers with 13 convolutional layers and 3 fully connected ones, and after constructing the same neural network in the VGGNet structure, authenticity and counterfeiting can be determined. On the other hand, if it is determined to be a genuine product, the inserted information is extracted. If it is determined to be a counterfeit using the VGGNet, the counterfeit result is sent to the user terminal 100. On the other hand, if it is determined to be authentic, the inserted information is extracted.

$$BestSpatialMatch=\text{min}\left(SAD\left(i,j\right)\right)$$

wobei C(k,l) eine in der Fälschungs-prüfeinheit 370 gespeicherte Design- Bitebene, und R(k,l) stellt eine entsprechende Bitebene dar, die an der Fälschungs-prüfeinheit 370 empfangen wird. Die globale räumliche Übereinstimmung sind dabei die optimale räumliche Koordinate, d. h. die Koordinate, bei denen die Summe der BestSpatialMatch-Absolutwertdifferenzen minimal ist. An diesen Koordinaten wird jede Musterinformation mit der maximalen Korrelation durch einen blockweisen Vergleich zwischen jeder Musterinformation des in der Fälschungs-Prüfeinheit 370 gespeicherten Design-QR-Code-Bildes und dem aktuell eingegebenen QR-Code-Bild extrahiert. Die Gleichungen hierfür sind wie folgt Gleichung 3 und Gleichung 4: $$cor\left(P^i,R_m\right)=\frac{{\displaystyle \sum _{k=1}^b{\displaystyle \sum _{l=1}^b\left(P^i\left(k,l\right)-\overline{P^i}\right)\left(R_m\left(k,l\right)-\overline{R_m}\right)}}}{\sqrt{{\displaystyle \sum _{k=1}^b{\displaystyle \sum _{l=1}^b{\left(P^i\left(k,l\right)-\overline{P^i}\right)}^2}}}\sqrt{{\displaystyle \sum _{k=1}^b{\displaystyle \sum _{l=1}^b{\left(R_m\left(k,l\right)-\overline{R_m}\right)}^2}}}}$$

$$cod{e}_m=\underset{i}{\text{arg}max}cor\left(P^i,R_m\right)$$

The information inserted in the genuine QR code can be extracted and provided to the user, and the QR code recognized as genuine is divided into C, M, Y and K bit planes. For each bit plane, adaptive binarization is performed independently by the Otsu algorithm, and noise in the spatial domain is removed by applying a morphology technique. For a binarized image of size M×M, a global search is performed with each bit plane information stored in the counterfeit checking unit 370 to find the optimal spatial matching position. This can be mathematically expressed as a measurement value at location (i,j) as shown in Equation 1 and Equation 2 below: $$SAD\left(i,j\right)={\displaystyle \sum _{k=1}^N{\displaystyle \sum _{l=1}^N\left|C\left(k,l\right)-R\left(i+k,j+l\right)\right|}}$$

$$BestSpatialMatcH=\text{min}\left(SAD\left(i,j\right)\right)$$

where C(k,l) represents a design bit plane stored in the anti-counterfeiting unit 370, and R(k,l) represents a corresponding bit plane received at the anti-counterfeiting unit 370. The global spatial match is the optimal spatial coordinate, i.e., the coordinate at which the sum of the BestSpatialMatch absolute value differences is minimal. At these coordinates, each pattern information with the maximum correlation is extracted by a block-by-block comparison between each pattern information of the design QR code image stored in the anti-counterfeiting unit 370 and the currently input QR code image. The equations for this are as follows Equation 3 and Equation 4: $$cOr\left(P^i,R_m\right)=\frac{{\displaystyle \sum _{k=1}^b{\displaystyle \sum _{l=1}^b\left(P^i\left(k,l\right)-\overline{P^i}\right)\left(R_m\left(k,l\right)-\overline{R_m}\right)}}}{\sqrt{{\displaystyle \sum _{k=1}^b{\displaystyle \sum _{l=1}^b{\left(P^i\left(k,l\right)-\overline{P^i}\right)}^2}}}\sqrt{{\displaystyle \sum _{k=1}^b{\displaystyle \sum _{l=1}^b{\left(R_m\left(k,l\right)-\overline{R_m}\right)}^2}}}}$$

$$cOd{e}_m=\underset{i}{\text{arg}max}cOr\left(P^i,R_m\right)$$

Here, Pi(k,l) means the pixel value of the i-th pattern at the (k,l) position in the b×b block, and (bar)Pi represents the average pixel value of the corresponding pattern. The m-th block Rm(k,l) means the pixel value at the (k,l) position for the m-th block of the currently input corresponding bit plane, and (bar)Rm is the average pixel value of the block Rm(k,l).

A pattern for the m-th block is obtained by finding a pattern where the correlation measured by Equation 3 is maximum. In this way, for each CMYK bit level, the code with the highest correlation among each individual pattern is selected, and the information inserted into the QR code is extracted based on the decoded code information.

When generating a QR code using the CMYK color and pattern information of the QR code, information such as product manufacturer, year, and month are converted into bit information. In addition, RS (Reed-Solomon) codes are combined as characters for error correction to flexibly respond to errors in inserted information. A QR code is generated using CMYK color and pattern information for a series of combined information sequences. Here, the basic block representing the CMYK color and pattern information is in the form of a pixel block of size N×N, where the larger this block is, the more reliably the decryption is predicted, but the less information is inserted.

The anti-counterfeiting unit 380 can store the QR code imaged with anti-counterfeiting pattern data when the QR code is etched on the back of the watch by the manufacturer server 400 using the anti-counterfeiting pattern generator. Recently, the Korea Institute of Machinery and Materials has developed an anti-counterfeiting pattern generator using Korean Patent Application No. 10-1688613 (published on January 2, 2017), an anti-counterfeiting pattern can be engraved on the back of the watch, and it is also possible to engrave an anti-counterfeiting pattern using Korean Registered Patent No. 10-1597754 (published on February 25, 2016), which is a method for detecting the anti-counterfeiting patterns. In this way, only watches with anti-counterfeiting patterns are checked for authenticity, and otherwise they can be treated as counterfeits.

When a block is generated after the watch is initially registered on the user terminal 100 in the blockchain, stored in a transaction, a new block is linked with respect to the block of the user terminal 100, and then an attempt to branch the block into a plurality is detected, an anti-counterfeiting destruction unit 390 determines whether or not it is genuine based on the result of the QR code imaged with anti-counterfeiting pattern data taken by a CCD (Charge-Coupled Device) camera, and destroys the branch of a block intended to store a transaction for a block of the watch that has been determined to be fake. For example, when the owners are connected in the order of A-B-C, etc., each block that forms the blockchain and stores the contents of the transaction is connected in series. When the trunk line running from C to D branches into two branches, that is, the branch of the block that is intended to store a transaction for a block of the watch that has been determined to be fake, the branch of the block that is intended to store a transaction for a block of the watch that has been determined to be fake is connected in series. that is, if the owner of the counterfeit product tries to authenticate with a watch engraved with the same QR code to create a watch register, it will be detected and one of the two branches will be destroyed. This is because a watch cannot be owned by two owners at the same time and two watch registers cannot be created for a watch. Then a CCD camera or the like is required to detect the anti-counterfeiting patterns, but for details, please refer to the Korean patent mentioned above, and a detailed description is superfluously omitted.

The counterfeit tracking unit 391 may store the user's biosignal acquired by the smart watch from the user terminal 100 if the watch is a smart watch, and may check for loss with the user terminal 100 when an outlier occurs in which the user's biosignal exceeds the preset pattern before the ownership transfer event of the watch register occurs, and if not, extract information from the smartwatch where the outlier occurred and register it as a fake.

The document checking unit 393 may, when a transfer of ownership occurs after the watch register is created by the initial registration of the user terminal 100, receive the uploaded certificate of the seal for transfer of ownership from the user terminal 100 and the purchasing terminal respectively, and after checking the authenticity of the uploaded certificate of the seal, provide information on checking the authenticity of the uploaded certificate by the user terminal 100 and the purchasing terminal, and only when the certificates of the seal of the user terminal 100 and the purchasing terminal are original, allow the entries for transfer of ownership in the watch register.

The QR code on the back of the watch can be a code etched by at least one laser irradiator. In this case, the certification of the seal is not transmitted to each user and buyer, but only the verification result, that is, the authenticity verification, is confirmed to each user and buyer. Through the verification of the parties to the ownership transfer contract, which is proven by documents, the possibility of the owner of a counterfeit product being registered in the watch register or creating a watch register can be completely eliminated.

The following describes an operation procedure according to the configuration of the service provider server described above for authenticity assessment of 2 in detail as examples of 3 and 4 described. However, it will be understood that the embodiment is only one of various embodiments of the present invention and is not limited thereto. However, it will be understood that the embodiment is only one of various embodiments of the present invention and is not limited thereto.

With reference to 3 (a) the authenticity evaluation service provider server 300 receives watch data, laser marking information and etching data, and QR code data, etc. from the manufacturer server 400 to construct a database of QR codes. (b) In the case of authenticity authentication of a watch after purchasing a watch on the user terminal 100, the authenticity evaluation service provider server 300 creates a watch register, registers the user of the user terminal 100, and inputs watch data and QR code data for each item. At this time, the user is registered in the "rights" field as the first owner, and the address, name, and the like can be registered.

As in (b) of 4 As shown, if the first owner is A, the transaction when the watch register is created, that is, the transaction of [store-owner A], will be created as a block based on owner A and linked in the blockchain. Then, when owner A sells to owner B through a second-hand platform, a block based on owner B will be created, and owner B's block storing the transaction of [owner A-owner B] will be linked next to owner A's block. If a block is created by owner C while the watch is being resold and the owner is constantly changing, and a branch of owner B is pending, after checking with owner C whether it is lost or transferred, if not, owner B's branch will be blocked and destroyed. As described above, in order to store a transaction, a certificate of the seal must be issued to each person and authenticated by the authenticity evaluation service provider server 300 of the present invention, after which an ownership transfer contract can be concluded and a block of transaction data can be created based on this contract, so that the block already created can be assumed to be the block of the real buyer. This allows branches after a block already created to be automatically destroyed.

(b) The authenticity assessment service provider server 300 can thus track and manage distribution channels and verify who owns a counterfeit product using an anti-counterfeiting pattern as in (c). As in (d), the handover document, e.g. the seal certification, is checked, the contract is only continued after checking whether the seal certification is original or not, and the integrity and unforgeability of the blockchain block are also maintained, so that attempts to create a watch register with a counterfeit product rather than a genuine product and to manipulate the watch register of the authenticity assessment service provider server 300 by obtaining authenticity authentication with a fake QR code can be fundamentally ruled out.

Since the data entered into the procedure for providing services for the authenticity assessment of watches using the QR code in the 2 to 4 details not described are the same like the in in 1 for methods for providing services for authenticating watches using the QR code, or can be easily derived from these facts, the following description is omitted.

5 is a flowchart showing a process of sending and receiving data between the components of the system for providing services for the authenticity assessment of watches using the QR code from 1 according to an embodiment of the present invention. In the following, an example of a process in which data is sent and received between each component is illustrated by 5 described, but the present application is not limited to such an embodiment and is interpreted, and it is obvious to the person skilled in the art that the process of sending and receiving the 5 shown data can be changed according to various embodiments described above.

With reference to 5 the authenticity evaluation service provider server receives and registers the QR code etched on the back of the watch from the manufacturer server (S5100), and when the user terminal picks up or scans the QR code, it checks whether the picked up or scanned QR code and the QR code registered on the manufacturer server match (S5200).

In addition, the authenticity evaluation service provider server transmits the authenticity verification result to the user terminal when the QR code registered on the manufacturer server and the captured or scanned QR code match (S5300).

The order between the steps described above (S5100 to S5300) is only an example and is not limited to this. That is, the order of the steps described above (S5100 to S5300) can be changed mutually, and some of the steps can be executed simultaneously or deleted.

Since the data entered into the procedure for providing services for the authenticity assessment of watches using the QR code in the 5 details not described are the same as those in 1 until 4 for methods for providing services for authenticating watches using the QR code, or can be easily derived from these facts, the following description is omitted.

The method for providing services for the authenticity assessment of watches using a QR code in accordance with a 5 The embodiment described may also be implemented in the form of a recording medium containing instructions executable by a computer, such as an application or program module executed by a computer.

A computer-readable medium can be any available medium that can be accessed by a computer, and includes both volatile and non-volatile media, as well as removable and non-removable media. In addition, the computer-readable medium can be any computer storage medium. A computer storage medium includes both volatile and non-volatile, removable and non-removable media implemented using any method or technology for storing information, such as computer-readable instructions, data structures, program modules, or other data.

The above-described method of providing services for authenticity evaluation of watches using a QR code according to an embodiment of the present invention can be executed by an application basically installed in a terminal (this may include a program included in a platform or an operating system basically installed in the terminal) and by an application (i.e., a program) directly installed by a user on a main terminal via an application providing server such as an app store server or a web server connected to the application or corresponding service. In this sense, the above-described method of providing services for authenticity evaluation of watches using a QR code according to an embodiment of the present invention is implemented as an application (i.e., a program) basically installed in a terminal or directly installed by a user, and can be recorded on a computer-readable recording medium.

The foregoing description of the present invention is for illustrative purposes, and those skilled in the art to which the present invention relates will understand that it can be easily modified into other specific forms without changing the technical spirit or essential characteristics of the present invention.
