Description

Genuine watch appraisal service using QR code {SYSTEM FOR PROVIDING GENUINE WATCH EVALUATING SERVICE USING QR CODE}

The present invention relates to a system for providing genuine watch appraisal service using a QR code, a system for etching a QR code on the back of a watch, generating a watch registration book, mapping each user and watch information to a QR code, and storing and managing the information. to provide.

The technology to prevent forgery and alteration of public documents and currency has a great influence on the forgery and alteration of objects, so even with a large budget, efforts to prevent such forgery and alteration are actively progressing, and the technology is making great progress. Damages to producers and consumers due to the attachment of copied or forged trademarks are also continuously increasing, and the world is suffering. Therefore, the development of technologies and frameworks that can effectively detect counterfeit trademarks at low cost will increase sales by blocking the distribution of counterfeit products on the producer side, and enable producers and consumers to trust and purchase products on the consumer side. Economic benefits can be created through reliable products for everyone.

At this time, a method for authenticating authenticity or detecting forgery has been researched and developed. In this regard, prior art Korean Patent Publication No. 2014-0016121 (published on February 7, 2014) and Korean Patent Publication No. 2019-0023323 (Released on March 8, 2019), when receiving an authentication request from a store terminal, the server searches the database to check whether the product is genuine, registers the product for which certification has been requested, and sends the confirmation of genuine product and the newly registered authentication request to the web link. After encoding, a QR code is generated and transmitted to the store terminal, and the store terminal prints the QR code and attaches it to the activation card, and to detect forgery of the QR code, A configuration for extracting a genuine product certification history through genuine product certification information and comparing it with a pre-stored product product certification history to check whether a QR code has been forged or altered is disclosed.

However, in the former case, when a store requests authentication, a QR code is generated, received at the store, and printed with a printer. Therefore, if each store uses a different printer or uses different label paper, the counterfeiter can use the same QR code. Even if you print it, there is no way to determine it. Even in the latter case, it is said that the activation history stored in the server and the activation history of the QR code are compared, but if the QR code itself is counterfeit, it is not possible to know whether it is a genuine authentication history or a counterfeit product certification history. Since the QR code of is stored in the server as it is even when authentication is requested, there may be a case where only the distribution route of the counterfeit product is stored. Therefore, research and development of a system for accurately checking whether a product is genuine while using a QR code is required.

One embodiment of the present invention, the QR code is etched on the back of the product, and the user terminal can inquire whether the product is genuine through an application, and the user who sold and purchased the product can check whether the product is owned by the vehicle registration By managing them together, it is possible to provide a genuine certification framework that can effectively detect counterfeit products while minimizing the cost added to product production. In particular, QR A genuine watch appraisal service providing system using a code may be provided.

2 is a block diagram for explaining the appraisal service providing server included in the system of FIG. 1, and FIGS. 3 and 4 are an embodiment in which a genuine watch appraisal service using a QR code is implemented according to an embodiment of the present invention. It is a drawing for explaining an example.

Referring to FIG. 2, the evaluation service providing server 300 includes a registration unit 310, a genuineness assessment unit 320, a result transmission unit 330, a registration register generation unit 340, an ownership transfer recording unit 350, and specifications. It may include a storage unit 360, a forgery confirmation unit 370, a counterfeit prevention unit 380, a counterfeit product annihilation unit 390, a counterfeit product tracking unit 391, and a document confirmation unit 393.

An emotion service providing server 300 according to an embodiment of the present invention or another server (not shown) operating in conjunction with at least one user terminal 100 and at least one manufacturer server 400 is a watch using a QR code. When a genuine appraisal service application, program, app page, web page, etc. is transmitted, at least one user terminal 100 and at least one manufacturer server 400 use a QR code to watch genuine appraisal service applications, programs, and apps. It can install or open pages, web pages, etc. In addition, the service program may be driven in at least one user terminal 100 and at least one manufacturer server 400 by using a script executed in a web browser.

For example, Netscape , Explorer, Chrome, and the like. In addition, an application means an application on a terminal, and includes, for example, an app running on a mobile terminal (smart phone).

Referring to FIG. 2 , the registration unit 310 may receive and register a QR code etched on the back of the watch from the manufacturer server 400 . The manufacturer server 400 may upload the QR code after etching the QR code on the back of the watch. At this time, a laser may be used for etching, and different methods may be applied depending on the material of the watch. Laser marking is a method of printing logos, product names, serial numbers, and model numbers through surface melting, burning, peeling, oxidation, cutting, and discoloration by irradiating laser light to a target object. It is largely divided into two types: mask type and scan type. . At this time, color development is largely divided into foaming, condensation, carbonization, and chemical change, and CO2 laser, YVO4 laser, YAG laser, etc. can be selected according to the material and processing method of the target object. Depending on the back material of the watch, a suitable processing method can be used and various laser marking machines can be used.

At this time, when a bullet is fired from a gun, a unique steel wire is left on the bullet, which serves as a fingerprint of the gun and is used to identify the owner of the gun. Similarly, a printer such as a printer has a method for specifying a printer according to which type of paper is used and which type of printer is used. Similarly, laser marking is a high-speed, non-contact technology that applies a permanent mark on a metal or plastic surface, and uses a focused wavelength of light known as laser light to permanently change the contrast of a specific area on the surface and mark it. (or substrate), marking type, speed, pulse frequency, laser settings such as power, etc., there are variables that change the QR code formed by laser marking. Manufacturers combine and select laser type, material type, mark type, laser setting, etc. Using this variable, it can be used as information to determine whether it is genuine when a counterfeit product with the QR code etched is found later. there is.

<Security QR Code>

The security QR code functions to search for information by recognizing the QR code with a general smartphone camera and prevent its use for other purposes. The original QR code information is first transformed using the AES symmetric key encryption algorithm. After that, the transformed data is secondarily encrypted using the private key of the RSA public key encryption algorithm to finally generate a QR code composed of binary values. The application of the user terminal 100 may recognize the binary QR code, perform decryption using the public key of the RSA public key algorithm loaded in the application, and then request authentication from the emotion service providing server 300. Circular QR code information may be obtained by using the modified QR code data requested from the appraisal service providing server 300 using an AES symmetric key. Security QR code generation uses RSA public key encryption algorithm to distinguish genuine applications from counterfeit applications that do not have public keys. Even if the key is exposed or the value decrypted with the public key is found, the original value of the QR code cannot be known because it is a modified QR code value. Therefore, even if a genuine product or a counterfeit product is arbitrarily manipulated, the manager can quickly compare it to determine whether it is a genuine product or a counterfeit product.

<Activation application>

The activation application provides both security authentication service and management service, and has a QR code scanning function and administrator mode. The secure QR code can be decrypted using the public key of the RSA public key algorithm only through the camera function installed in the activation application. In addition, a page displayed when a genuine QR code is recognized through a genuine product certification application may be provided, and the number of times the genuine product certification of the corresponding QR code has been performed may be displayed in numbers. The manager mode may have a QR code generation function, a search function according to QR code number and product name, a detailed view function, and a function of displaying a place where QR code authentication is requested on a map.

When a QR code is created, it is stored in the database in the form of a string and automatically updated in the manager mode list. Administrators can delete QR codes for products that are suspected of duplicating QR codes or that are no longer handled. The user's location information collected in the authentication process is also displayed, and it is possible to easily recognize the QR code that exceeds the set threshold by categorizing it by color according to the number of inquiries. QR code duplication detection is a method in which administrators and users are notified when the same QR code is authenticated at a similar time in a distant location and when the same QR code is authenticated with different smartphones using a single-use QR code. can be used.

<Activation Distribution Tracking>

The program for activation using a QR code uses AWS's cloud server, EC2, and the database can use MySQL. It can be designed to be equipped with AES symmetric key algorithm and RSA public key algorithm and database used for QR code security. The data transmission method between the server and the client can be transmitted and received in a POST method without exposing data and having no limit on the transmission length. After comparing the received data with the data in the database, the activation page can be printed.

When a QR code is photographed or scanned by the user terminal 100, the authenticity appraisal unit 320 may check whether the photographed or scanned QR code and the QR code registered in the manufacturer server 400 match. The user terminal 100 may photograph or scan the QR code on the back of the watch to receive and output a result of appraisal whether the watch is genuine or not.

The result transmission unit 330 may transmit the authenticity confirmation result to the user terminal 100 when the QR code registered in the manufacturer server 400 and the photographed or scanned QR code match.

When a purchase is made in the user terminal 100, the registration book generating unit 340 includes the user name of the user terminal 100, the user address, the user contact information, the issuing manufacturer name, the first registration date of the watch, the unique identification number of the watch, and the watch. A watch registration book including a model name, year, QR code, at least one part name of the watch, size of the watch, total weight of the watch, factory price of the watch, purchase route, and receipt may be generated. Just as there is a vehicle registration book in each car, in one embodiment of the present invention, a clock registration book is created based on the user who registers for the first time, and in the case of ownership transfer, the owner is continuously described in a format similar to real estate registration. can be created At this time, if A/S (After Service) or repair details exist, they can be included and stored in the generated watch registration book. The transaction data (contents of the ownership transfer contract) of the watch register created in this way can be created and stored for each owner in each block of the blockchain.

The reason why transaction data, rather than the watch register itself, is put into each block and linked is to catch two buyers trying to authenticate at the same time or time difference, such as a double sale of real estate, using forged QR codes. When two buyers authenticate, two buyers arise from one seller (user), and the blocks that were connected in series suddenly branch into two. This is to prevent the occurrence of divergence itself by monitoring and capturing the occurrence of divergence into two, and to prevent the generation and distribution of two or more different watch registers in one watch. This is because if the reliability of the watch registration book itself is broken, the QR code of the present invention also has no meaning in authenticating genuine products. Of course, the appraisal service providing server 300 and the manufacturer server 400 of the present invention can also manage the watch registration book to check who the real buyer is, but two buyers, that is, a real buyer and a non-true buyer, either at the same time or with a time difference. In the case of claiming that it is a genuine watch register, two watch registers, that is, watch registers of different double sales by the buyer, are circulated, and a bona fide third party who believes in them reports only the watch register, which is a counterfeit watch, until it is disclosed. This is because there is a possibility of being damaged by giving and buying at the genuine price.

When the user terminal 100 registers the watch for the first time after authenticating the watch, the ownership transfer recorder 350 creates a watch registration book based on the user of the user terminal 100, and takes ownership from the user terminal 100 to the purchase terminal. When this is transferred, a transaction between the user terminal 100 and the purchasing terminal may be recorded by creating and connecting a new block to the blockchain.

When a QR code is uploaded from the manufacturer server 400, the specification storage unit 360 includes etching data including the size of the QR code, etch width, etch length, and etch depth, and specifications including photo data of the QR code. Data can be uploaded and stored.

When the QR code is captured by the user terminal 100, the forgery check unit 370 detects and compares the characteristics of the image to analyze the identity between the image of the QR code and the image in the specification data, and then determines whether or not the QR code is the same. You can check. At this time, it is assumed that the counterfeit QR code is copied from the genuine QR code using a high-quality scanner. Here, it is premised that color information designed as an RGB color model through a scanner is designed based on the RGB color model on a PC, and distortion may occur because it must be converted into a vector file for laser etching in the process of actual printing.

<QR code image pre-processing>

For image pre-processing, after receiving the image including the QR code taken by the user terminal 100 using the application in the forgery confirmation unit 370, first converting it into a luminance signal (GrayScale), and then extracting black and white information Recognize the QR code. At this time, if the QR code is not recognized or accurate shooting is not performed, the forgery confirmation unit 370 may request re-capturing to the user terminal 100 . When the QR code is recognized, image cropping is performed for the QR code part based on the center point of the finder pattern existing in the QR code. The image of the cropped QR code part is warped into an M×M size image. Using the color image processed in the pre-processing block, it is possible to determine whether the product is genuine or fake (counterfeit) based on a convolutional neural network algorithm for authentication.

First, since the illuminance value of the image is all different depending on the place where the user is located, the time, and the performance of the smartphone, histogram matching and spatial matching are performed with the genuine QR code stored in the forgery checking unit 370. VGGNet is learning various types of genuine QR codes and counterfeit QR codes in advance. A genuine QR code or a fake QR code can be determined by using a learned neural network using a typical VGGNet structure among convolutional neural networks. At this time, after adjusting the size of the input image to 224 × 224, VGGNet can be composed of a total of 16 layers with 13 layers of convolution and 3 layers of full connection. can judge If the product is determined to be a fake product based on VGGNet, the result of the fake product is transmitted to the user terminal 100 . On the other hand, if it is determined to be genuine, inserted information is extracted.

<Extract Insertion Information>

Information inserted into the genuine QR code can be extracted and provided to the user, and the QR code determined to be genuine is separated into C, M, Y, and K bit planes. For each bit plane, adaptive binarization is independently performed through the Otsu algorithm, and spatial domain noise is removed by applying a morphology technique. An optimal spatial matching position is found by performing a global search with each bit plane information stored in the forgery checking unit 370 for the binary image of size M×M. If the measured value at the position (i, j) is expressed as an equation, it can be organized as Equation 1 and Equation 2 below.

Here, C(k,l) is a design bit-plane stored in the counterfeit checker 370, and R(k,l) represents a corresponding bit-plane received by the counterfeit checker 370. In this process, the global spatial matching is the optimal spatial coordinate, that is, the coordinate at which the sum of the absolute difference between BestSpatialMatch is the minimum. At these coordinates, each pattern information having the maximum correlation is extracted through a block-by-block comparison between each pattern information of the design QR code image stored in the forgery checking unit 370 and the currently input QR code image. Equations for this are as follows Equation 3 and Equation 4.

Here, Pi(k,l) means the pixel value of the ith pattern at the (k,l) position in the b×b block, and (bar)Pi represents the average pixel value of the 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 bit plane, and (bar)Rm is the average pixel of the block Rm(k,l) show value A pattern for the m-th block is obtained by finding a pattern in which the correlation measured by Equation 3 is maximized. In this way, for each bit plane of CMYK, the code with the highest correlation among each pattern is selected, and information inserted into the QR code is extracted using 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 is converted into bit information. In addition, RS (Reed-Solomon) codes are combined as codes 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. At this time, the basic block representing the CMYK color and pattern information has the form of a pixel block of size N×N. As the block size increases, stable decoding is predicted, but the amount of embedded information decreases.

The anti-counterfeiting unit 380 may map and store the anti-counterfeiting pattern data to the QR code when etching the QR code on the back of the watch in the manufacturer server 400 using the anti-counterfeiting pattern generator. Recently, the Korea Institute of Machinery and Materials developed an anti-counterfeiting pattern generator. When using Korean Patent Registration No. 10-1688613 (published on January 02, 2017), an anti-counterfeiting pattern can be engraved on the back of the watch, and the anti-counterfeiting pattern can be If you use Korea Patent Registration No. 10-1597754 (published on February 25, 2016), which is a detection method, you can also detect anti-counterfeiting patterns. In this way, genuine authentication is performed only for watches with anti-counterfeiting patterns, and counterfeit products can be processed if they do not.

After the watch is initially registered in the user terminal 100, the fake product annihilator 390 creates a block in the blockchain and stores it in a transaction, and after a new block is connected based on the block of the user terminal 100, the block is multiplied. When a diverging attempt is detected, the QR code to which the anti-counterfeiting pattern data is mapped is photographed with a CCD (Charge-Coupled Device) camera to determine whether the watch is genuine, and the transaction for the block of the watch judged to be non-genuine is processed. You can eliminate branching of blocks you want to save. For example, in the case of owner A-B-C, etc., each block constituting the block chain that stores the contents of the transaction is connected in series. At this time, the trunk line passing from C to D branches into two branches, that is, when the owner of the counterfeit product tries to authenticate with a watch engraved with the same QR code to create a watch registration book, it detects this and branches one of the two is to annihilate This is because one watch cannot be owned by two owners at the same time, and two watch registers cannot be created for one watch. At this time, in order to detect the anti-counterfeiting pattern, a CCD camera or the like is required, and for details thereof, reference is made to the above-mentioned Korean registered patent, and a detailed description thereof will be omitted redundantly.

If the watch is a smart watch, the counterfeit tracking unit 391 stores the user's biological signal of the user terminal 100 sensed by the smart watch, and the user's biological signal is preset until the ownership transfer event of the watch registration book occurs. If an outlier beyond the pattern occurs, whether or not the watch is lost is checked with the user terminal 100, and if it is not lost, information on the smart watch where the outlier has occurred can be extracted and registered as a counterfeit.

The document confirmation unit 393 uploads a seal certificate for ownership transfer from the user terminal 100 and the purchase terminal, respectively, when the ownership transfer occurs after the watch registration register is created by the initial registration of the user terminal 100 After receiving and verifying the authenticity of the uploaded seal certificate, the user terminal 100 and the purchase terminal guide information on whether or not the authenticity of the seal certificate is verified, and the user terminal 100 and the purchase terminal seal certificates are original. A record for the transfer of ownership may be accepted in the Watch Registry. The QR code on the back of the watch may be a code etched through at least one laser irradiator. At this time, the seal certificate is not transmitted to each user and purchaser, but only the confirmation result, that is, whether authenticity is confirmed, is confirmed to each user and purchaser. By confirming the parties to the ownership transfer contract, which is proved by documents, the possibility of the owner of a counterfeit product being recorded in the watch registration book or creating a watch registration book can be fundamentally blocked.

Hereinafter, an operation process according to the configuration of the above-described emotion service providing server of FIG. 2 will be described in detail with reference to FIGS. 3 and 4 as examples. However, it will be apparent that the embodiment is only any one of various embodiments of the present invention, and is not limited thereto.

Referring to FIG. 3 , (a) the appraisal service providing server 300 receives watch data, laser marker information and etching data, and QR code data from the manufacturer server 400 to build a database of QR codes. (b) When authenticating a watch after purchasing a watch from the user terminal 100, the appraisal service providing server 300 creates a watch registration book, registers the user of the user terminal 100, and watches data and QR code data. Enter for each item. At this time, the user is recorded in the right column as the first owner, and the address, name, and the like may be recorded.

As shown in (b) of FIG. 4, if the first owner is A, the transaction when the watch register is created, that is, the transaction of [Store-Owner A], is created as a block based on owner A and linked in the blockchain. . Then, if owner A sells to owner B through used platforms such as Used Nara or Carrot Market, a block is created based on owner B, and the owner whose transaction of [Owner A-Owner B] is stored next to Owner A's block The blocks of B are connected. While the clock is being resold and the owner continues to change, if a block of owner C is created and a branch is about to branch off from owner B, after checking whether it has been lost or transferred to owner C, if not, a branch from owner B Block branches and destroy them. As described above, in order for a transaction to be stored, an ownership transfer contract can be concluded after each person receives a seal certificate and authenticity is confirmed by the appraisal service providing server 300 of the present invention, and based on this, a block containing transaction data can be created Since there is, it can be assumed that blocks that have already been created are truly buyer's blocks. Therefore, branches after blocks have already been created can be automatically destroyed.

(b) The appraisal service providing server 300 can track and manage distribution channels in this way, and can check who owns a counterfeit product by using an anti-counterfeiting pattern as in (c). As in (d), the integrity of the blockchain block and the impossibility of counterfeiting are maintained because the previous document, for example, the seal certificate is checked and whether the seal certificate is original or not, and the contract is proceeded. An attempt to manipulate the watch registration book of the appraisal service providing server 300 by generating a watch registration book or authenticating the watch registration book with a counterfeit QR code can also be fundamentally excluded.
