SYSTEM AND METHOD FOR MANAGEMENT OF ELECTRONIC FINGERPRINT FOR PREVENTING FORGERY OR ALTERATION OF ART PIECES, METHOD FOR DETECTING FORGERY OR ALTERATION OF ART PIECES AND COMPUTER PROGRAM FOR THE SAME}

Embodiments relate to an electronic fingerprint management system and method for preventing forgery of a work of art, a forgery determination method of a work of art, and a computer program therefor. More specifically, the embodiments relate to a technique for converting a microstructure of a material used or intended to be used in a work of art into an electronic fingerprint and using the electronic fingerprint to prevent or determine forgery of the artwork.

Works of art that have artistic and aesthetic elements such as paintings, calligraphy, sculptures, crafts, sculptures, and musical instruments often vary in their economic and conservative values, depending on the creator of the art. Art works produced by prominent or individualized creators have high economic value due to their workability and rarity, so imitations that mimic such works are hard to distinguish from genuine ones.

In order to identify such counterfeit products and screen out the originals, experts in the field have to go through verification for authenticity identification for a long time. However, in spite of these verifications, not only does the verification result be consistent for each expert, but even if the result is genuinely identified by the expert, the result may be inaccurate. There is this.

In order to make up for this drawback, recently, a technique for acquiring a certain attribute from a work of art using a photographing equipment and the like and using the same to judge the authenticity of a target work of art has emerged. However, the authenticity evaluation method using the equipment developed to date has a problem that it is not difficult to produce counterfeit goods that can bypass the information because the form of the information for determining authenticity or the determination process is not technically advanced. The management of Korean art is done separately from the distribution of the material of art, so there is a problem that information related to art is not managed collectively and comprehensively.

For example, Korean Patent Publication No. 10-2009-0032637 discloses a technique of capturing fingerprint image data from a work of art and using the same to judge the authenticity of the work of art. However, the fingerprint image data of Korean Patent Laid-Open Publication No. 10-2009-0032637 refers to a fingerprint of an artist or a connoisseur of emotion, and there is a possibility of fingerprint forgery, even if the connoisseur's fingerprint is not forged. It's hard to guarantee. In addition, since the artist or the connoisseur has to leave fingerprints for each individual art, it is cumbersome to manage and it is impossible to collectively and comprehensively manage the works of various artists.

That is, the electronic fingerprint management system 3 and the user devices 1, 4, and each unit included therein are hardware for processing and / or transmitting and receiving data of a specific format and content and / or in an electronic communication method. The related software can be referred to collectively.

For example, the hardware may be a data processing device including a CPU or other processor. In addition, software driven by hardware may refer to a running process, an object, an executable, a thread of execution, a program, or the like.

The user device 1 is a device for use by a user who wants to register an electronic fingerprint of the material 100 used or to be used in a work of art. For example, the user of the user device 1 may be a writer who authors an artwork using the material 100, may be a sales company of the material 100, or a business agent who only registers an electronic fingerprint. It may be. In addition, the user device 4 may be used by a user who wants to check the authenticity of the target artwork 200 using information read from a Near Field Communication (NFC) tag of the target artwork 200.

However, as an example, the user devices 1 and 4 may be any other computing device such as another mobile communication terminal, a notebook computer, a personal digital assistant, a tablet computer, or the like.

Each element constituting the electronic fingerprint management system 3 is not intended to necessarily refer to separate devices that are physically separated from each other. That is, the units 31 to 36 shown in FIG. 1 merely functionally classify the hardware constituting the electronic fingerprint management system 3 according to an operation performed by the hardware, and each unit must be independent of each other. It does not have to be provided. Of course, according to the exemplary embodiment, one or more of the parts 31 to 36 illustrated in FIG. 1 may be implemented as separate devices that are physically separated from each other.

Specific operations of the units 31-36 and the user apparatuses 1 and 2 associated with the electronic fingerprint management system 3 will be described in detail below with reference to FIG. 2.

2 is a flowchart illustrating each step of the electronic fingerprint management method for preventing forgery of the artwork according to an embodiment.

1 and 2, the electronic fingerprint management system 3 according to an embodiment of the present invention intends to register an electronic fingerprint using a material 100 that has not yet been registered, the photographing unit 31, And a fingerprint extractor 32 and a fingerprint register 34.

In the present specification, the material refers to a material for authoring a work of art, for example, in the case of a painting, a canvas corresponds to the material. The canvas is made of ore or cloth as the main material and is optionally dried on top of it with Gesso or other paints. Mines and fabrics are made of a combination of weft and warp yarns, and due to the twisting of each thread, the connection part of the broken thread, and the scattering of the thread, the microstructure of each canvas is different from each other like a human fingerprint. There is nothing. The present invention focuses on this point and proposes a technique to electronically codify the microstructure of the material used or to be used in the art work, thereby preventing forgery and alteration.

In the present specification, the material is described based on the canvas, but the material may be any article capable of electronic paper culture because it has a unique microstructure for each product, and is not limited to the canvas. For example, in the case of calligraphy works, paper such as cloth or Korean paper may correspond to the material, and in the case of ceramic works, clay or soil may correspond to the material.

In order to register the electronic fingerprint, first, the photographing unit 31 photographs the microstructure of a part of the material 100 (S11). In this case, the material 100 may be a canvas in which a picture is already drawn, or may be a blank canvas in a state before drawing. In the case of a blank canvas, a high-resolution camera can be used to shoot a strong light from the back of the canvas, and the fiber tissue of the canvas. On the other hand, in the case of a canvas on which a picture is drawn, the simple drawing allows the paint to be drawn on top of the canvas rather than the microstructure of the canvas. Thus, as a non-destructive method for acquiring the microstructure, X-rays or ultrasonic waves are set to a predetermined depth from the surface of the canvas. The microstructure can be photographed by converging X-rays or ultrasonic waves to the fiber tissue of the canvas itself, not through paint.

Alternatively, depending on the material of the canvas, the microstructure of the canvas fiber may be photographed by brightening the brightness of the light above a predetermined value without using X-rays or ultrasonic waves. In this case, light refers to visible light. For example, a fibrous tissue of the canvas may be photographed by illuminating a strong light of 10,000 lux or more, which is about the brightness of daylight. However, the brightness of the light for photographing the microstructure is not limited thereto.

The principles described above can be similarly applied to the materials of other works of art, such as Korean paper and earth, in addition to canvas.

The fingerprint extracting unit 32 performs digital conversion of the microstructure in order to electronically culture the microstructure photographed by the photographing unit 31 (S12). 3A and 3B are images illustrating a process of digitally converting a microstructure of a material according to an electronic fingerprint management method for preventing forgery of a work of art, according to an embodiment. The digital conversion step S12 is further described with reference to FIGS. 3A and 3B. It explains in detail.

Referring to FIG. 3A, the mineral wood or fabric constituting the canvas includes a plurality of wefts 401 and a plurality of warp yarns 402 that cross each other. At this time, the combination of the weft yarn 401 and the warp yarn 402 has a unique shape for each part due to the twisting or disconnection of the broken thread, the scattering or loosening of the thread, or the foreign matter. In this case, referring to FIG. 3B, the fingerprint extracting unit 32 has a grid 300 having a plurality of unit units 301 corresponding to the shapes of the weft 401 and the warp 402 that cross each other. By digitizing the fine structure of the canvas. Each unit unit 301 of the grid 300 has a specific brightness value. That is, the grid 300 has a structure similar to a bitmap image in which the unit unit 301 is one unit pixel.

Due to the irregular shapes of the weft 401 and the warp 402 that cross each other, the brightness of each unit unit 301 of the grid 300 is different from each other. For example, when the microstructure is photographed from the front of the canvas while shining a strong light from the back of the canvas, if the weft yarn 401 or warp yarn 402 spans a relatively large area within the unit unit 301, the unit The unit 301 will appear to be relatively dark as the light is obscured by the weft 401 or warp 402. On the contrary, in the case of the unit unit 301 in which the weft yarn 401 or the warp yarn 402 passes through the unit unit 301 relatively little, since the light on the rear surface of the canvas passes through the front of the unit unit 301 relatively, This will appear relatively bright.

Accordingly, by calculating brightness values of regions corresponding to each unit unit 301 of the grid 300 in the photographed microstructure, irregular shapes of the weft 401 and the warp 402 that cross each other may be converted into digital information. Can be. In other words, the digital conversion information herein means an inherent brightness pattern obtained by irregular shapes of the weft 401 and the warp 402 that cross each other. Since the photographed microstructure may be in the form of an image having a plurality of pixels, the brightness value of each unit unit 301 of the grid 300 is the total sum of the brightness values of pixels located in the area corresponding to the unit unit 301. Alternatively, the brightness value may be an average value of the pixels.

For example, when the grid 300 is in the form of an array of unit units 301 including five rows each horizontally and vertically, the digital conversion information of the microstructure may be configured as shown in Table 1 below.

51 49 46 48 46 50 52 53 41 50 40 59 66 41 39 53 55 62 38 55 52 50 63 52 50

In one embodiment, in order to increase the reliability of the electronic fingerprint check in the forgery determination process to be performed later and to simplify the calculation, the brightness value of each unit unit 301 of the grid 300 is compared with a preset reference value and the corresponding brightness value The brightness value of each unit unit 301 may be converted into a binary value depending on whether the reference value is greater than or less than the reference value. For example, if the brightness value of the unit unit 301 is greater than or equal to the reference value, the brightness value may be converted to 1, and if the brightness value of the unit unit 301 is less than the reference value, the brightness value may be converted to 0. The reference value for the binary conversion of the digital conversion information may be a fixed specific brightness value, or may be determined using the brightness values of the pixels belonging to the grid 300. For example, the reference value may be an average value of brightness values of all unit units 301 belonging to the grid 300.

In the digital conversion information of the microstructure shown in Table 1, assuming that the reference value for binary conversion is 50, the digital conversion information of Table 1 may be simplified into a binary pattern as shown in Table 2 below.

One 0 0 0 0 One One One 0 One 0 One One 0 0 One One One 0 One One One One One One

Although the grid 300 having a simple structure of 5 × 5 has been described above for the sake of simplicity, it will be easily understood that the actual grid 300 is not limited thereto. By setting the size of the microstructure sufficient to obtain the electronic fingerprint and the size of each unit unit 301 to be included in the grid 300 corresponding to the microstructure sufficiently, the weft 401 and the warp that cross each other By the irregular shape of 402, the unique shape formed on each part of the canvas can be converted into unique digital information. In other words, regions having different microstructures in the material have different digital conversion information. To this end, in an embodiment, the horizontal length L _x and / or the vertical length of each unit unit 301 of the grid 300 may be well reflected by referring to the photographed microstructures. Determine (L _y ). As described above, the portion where the weft yarn 401 and the warp yarn 402 are located in the microstructure is relatively dark due to the light irradiated from the back of the canvas. Therefore, the weft yarn 401 and the warp yarn 402 may be detected by detecting a portion in which the brightness of the pixel changes rapidly in the photographed microstructure. This detection process can be easily understood by those skilled in the art from known image processing techniques, and thus a detailed description thereof will be omitted.

At this time, the fingerprint extracting unit 32 detects a plurality of wefts 401 located in the photographed microstructure, and considers the distance between the adjacent wefts 401 and the thickness of each weft 401, the grid 300 The horizontal length L _x of each unit unit 301 may be determined. For example, the horizontal length L _x of each unit unit 301 of the grid 300 may be a value obtained by adding the average value of the thicknesses of the respective wefts 401 to the average of the intervals between the adjacent wefts 401. have. Similarly, the fingerprint extractor 32 detects a plurality of warp yarns 402 located in the photographed microstructure, and considers the spacing between the warp yarns 402 adjacent to each other and the thickness of each warp yarn 402. The vertical length L _y of each unit unit 301 may be determined. For example, the vertical length L _y of each unit unit 301 of the grid 300 may be a value obtained by adding an average value of the thicknesses of the warp yarns 402 to the average of the intervals between the warp yarns 402 adjacent to each other. have.

According to the present embodiment, the grid 300 and the unit unit 301 are set to reflect the characteristics of the microstructure through image processing of the photographed microstructure. For example, the grid 300 may be generated such that one cell of the lattice formed by the weft 401 and the warp 402 intersects approximately one unit unit 301. The generated grid 300 reflects the overall characteristics of the fine structure of the canvas and at the same time reflects the unique shape of the fine structure in the form of the brightness value of each unit unit 301 of the grid 300. Therefore, the unique microstructure of the canvas can be converted into unique digital information.

However, this is merely an example, and in another embodiment, digital conversion information may be obtained by applying a grid having a fixed size unit unit without a separate image processing process for the microstructure. In another embodiment, digital conversion information may be obtained by randomly setting the total size of the grid and / or the size of each unit of the grid.

In addition, in one embodiment, the image processing to give a posterize (posterize) effect before the digital information conversion on the image photographed microstructure, and the digital conversion process of Figures 3a and 3b for the posterized image Electronic fingerprints can also be obtained by performing. The posterize process refers to a process of increasing the contrast value between each pixel of the image to facilitate digital conversion of the image, and this effect is well known as a function of known image processing programs.

4A to 4E are images illustrating each step of processing an image photographing a microstructure of a material according to an electronic fingerprint management method for preventing forgery of a work of art, according to an exemplary embodiment.

4A shows an original image photographing a microstructure, and FIGS. 4B to 4E show an image obtained by performing posterization processes of steps 1, 2, 3, and 4, respectively. As shown in the figure, the nonuniformity of the contrast of the fine structure of the image is gradually emphasized each time the posterize effect is applied, thereby obtaining an electronic fingerprint well reflecting the characteristics of the fine structure by performing digital conversion using the posterized image. There is an advantage to this. However, this does not limit the scope of the present invention, and depending on embodiments, it is also possible to obtain an electronic fingerprint by digitally converting the original image of the microstructure without a posterize process.

In FIGS. 3A to 4E, the process of digitally converting the microstructure of the material is described using a canvas composed of weft 401 and warp yarn 402 intersecting with each other. However, the same principle applies to other materials having different tissue structures. It will be readily understood by those skilled in the art that they can be applied.

That is, in the microstructure of the canvas, the weft yarn 401 and the warp yarn 402 correspond to the factors causing the change in the brightness value. In the above-described embodiment, the grid 300 corresponding to the microstructure is set using the unit and the unit is used. The brightness pattern of 301 was obtained as digital conversion information. However, in another embodiment, any other element that causes a change in brightness value in the material, such as the grain of the table, the state of the paper (lamination) of the paper, the agglomeration of soil or clay, and the like, the weft 401 and the warp 402 of the above-described embodiment. ) Can be used in the same way to set the grid and unit units corresponding to the microstructure. Therefore, the shape of the grid 300 is also not limited to the lattice form shown in FIG. 3, and different types of grids may be set according to the structure of the material.

In addition, the element which causes a change in the brightness value in the material is not limited to the visible light region. In the case of a material that is difficult to transmit visible light such as a canvas, or a table or ceramics already painted, X-rays or ultrasonic waves are transmitted to a certain depth on the surface of the material to photograph the microstructure of the material. In this case, the element causing the change in the brightness value in the material may refer to any tissue structure causing a difference in absorbance of X-rays or ultrasound.

Referring back to FIGS. 1 and 2, the fingerprint extractor 32 generates an electronic fingerprint including digital conversion information of a microstructure (S13). In addition, the fingerprint extraction unit 32 generates a unique number corresponding to the generated electronic fingerprint (S14). The unique number is an arbitrary number and / or string given to the material 100 that generated the electronic fingerprint. The unique number is used to manage the distribution of the material 100 and the authoring activity or sales of the artwork using the same. can do.

Next, the fingerprint registration unit 34 registers the electronic fingerprint and the unique number obtained by the fingerprint extraction unit 32 in the database 340 of the fingerprint registration unit 34 (S16). For example, when the blank canvas is shipped, the fingerprint registration unit 34 may register an electronic fingerprint, a unique number, a classification, a sale date, a standard, and the like corresponding to the canvas in the database 340. The electronic fingerprint registered in the database 340 may correspond to only one area of the material 100, or the material 100 is divided into a plurality of areas, and all the electronic fingerprints of each divided area are stored in the database 340. By registering, the electronic fingerprint of the entire area of the material 100 can be registered.

In one embodiment, the database 340 of the fingerprint registration unit 34 includes a location and size of photographing the microstructure from the material 100 to obtain an electronic fingerprint, the size of the grid 300, and / or the grid 300. Additional information such as the size of each unit unit 301 included is further stored. Such additional information is encrypted by a predetermined encryption protocol so that it can be decrypted only by the electronic fingerprint management system 3, thereby eliminating the possibility of imitation by a third party who has no authority to the electronic fingerprint.

For example, the photographing unit 31 photographs a microstructure of a specific size from a specific position of the material 100. For example, the microstructure may be photographed from a square having a width of 5 cm from the upper left corner of the raw material 100 to the right and 5 cm below the upper left corner. At this time, the fingerprint registration unit 34 may store the location where the microstructure is photographed and the size of the microstructure by encrypting it. Therefore, even if a third party deodorizes the electronic fingerprint, it is impossible to forge the microstructure of the genuine article without knowing where the microstructure is obtained and at what size. For example, if you change the shooting position and size of the microstructure randomly every time you obtain an electronic fingerprint, a third party will not be able to know what size and where the electronic fingerprint is located even if you seize the electronic fingerprint. It becomes impossible.

The same principle may be equally applied to the overall size of the grid 300 generated corresponding to the microstructure and the size of each unit unit 301 included in the grid 300. That is, the total size of the grid 300 and the size of each unit unit 301 included in the grid 300 may also be encrypted as additional information for the electronic fingerprint and stored in the database 340.

In one embodiment, the information itself registered in the database 340 of the fingerprint register 34 may also be encrypted. In addition, the database 340 of the fingerprint registration unit 34 may be implemented as a single server that cannot be accessed online by an external device or may be connected to a primary server and an external device that may be accessed online by an external device. It is implemented by dividing this impossible secondary server, and is configured to protect the electronic fingerprint information from security threats such as hacking. For example, the database 340 of the fingerprint registration unit 34 may be configured to register or modify information using only information received from a medium connected through a direct connection interface such as USB, thereby fundamentally preventing the possibility of hacking through the network. Can be excluded. Furthermore, the database 340 of the fingerprint register 34 automatically executes a virus or malware check on the medium even when the medium is connected through the direct connection interface to block the possibility of malicious database manipulation. It can be further configured.

On the other hand, not only the electronic fingerprint and the unique number are registered in the database 340 of the fingerprint register 34, but also the microstructured image itself as shown in Figs. 4A to 4E is also stored in the database 340 of the fingerprint register 34. You can also save. In this case, forgery forgery determination may be performed using an image of a microstructure if forgery determination by a unique number and / or an electronic fingerprint is not easy or a satisfactory result may not be obtained. The forgery determination process using the stored image may be performed by a known image processing method, and for this purpose, the image to be stored in the database 340 may be an image to which a posterize effect is applied as shown in FIG. 4E. It is not limited to this.

In one embodiment, the electronic fingerprint management system 3 further includes a communication unit 33. The communication unit 33 may receive, from the user device 1, the work information on the art work in which the material 100, which photographed the microstructure, is used (S15). The electronic fingerprint and the unique number of the material 100 may be stored in the database 340 of the fingerprint registration unit 34. The work information may include, but is not limited to, an artist's name, work date, description, title, material, classification, sale date, specification, short description, and a description of an artwork.

However, if the material 100 for photographing the microstructure is a blank canvas that has not been painted yet, only the electronic fingerprint and the unique number of the canvas are first registered in the database 340, and the work information registered using the canvas is registered. The process may be performed later. In this case, the canvas is released as a product in a blank state after registering its electronic fingerprint and a unique number in the database 340, the artist purchases the canvas to draw a picture at any time, such as during the authoring or completion of the work The work information may be input to the electronic fingerprint management system 3 directly or through an agency. For example, in this case, the work information may further include a writing intention or a later input of the artist about the work. Through the above process, it is possible to manage the work history through the electronic fingerprint management system (3) from the material distribution stage before the artwork.

In one embodiment, the electronic fingerprint management system 3 further includes a tag output unit 35. The tag output unit 35 outputs an NFC tag in which information corresponding to the electronic fingerprint is recorded (S17). In the present specification, the output of the NFC tag may refer to actually printing the NFC tag on paper such as a film, or to be recorded on the NFC tag to print the NFC tag using the user device 1 or another device. It may also refer to generating and transmitting only information.

A user who registers the electronic fingerprint of the material 100 may fix the NFC tag on which the information corresponding to the electronic fingerprint is recorded on the material 100. For example, a user may partially scrape the inside of a wooden frame or the like that does not damage the work on the canvas and seal the NFC tag therein, or attach the NFC tag on the surface of the canvas. In addition, the unique number of the electronic fingerprint or the seal mark may be imprinted at the position where the NFC tag is sealed. In addition to the canvas, NFC tags can be fixed in a similar way to other works of art such as tableware, Korean paper, and ceramics. The NFC tag fixed as described above is used when an artist who purchases a blank canvas and authors a work to register the work information in the electronic fingerprint management system 3, or reads the NFC tag from the target artwork 200. This can be used when determining the authenticity.

The information recorded in the NFC tag may be all or part of information registered in the database 340 in relation to the material 100 that photographed the microstructure. For example, all the electronic fingerprints of the entire area of the material 100 are registered in the database 340 of the electronic fingerprint management system 3, but only the electronic fingerprint corresponding to a specific part of the material 100 is recorded in the NFC tag. You may. Therefore, even if a third party succeeds in obtaining an electronic fingerprint by decrypting the information recorded in the NFC tag and manufactured the imitation article, the electronic fingerprint is obtained from the entire area of the imitation article and is pre-registered in the database 340. Comparing with the electronic fingerprint of the area, it can be determined that the forgery. In addition, the information recorded on the NFC tag may include an image of a microstructure converted into an electronic fingerprint as described above with reference to FIGS. 4A to 4E.

In addition, the information recorded on the NFC tag may include information on the work such as the artist's name, working day, history, title, material, classification, sale date, specification, brief description, entry details related to the work. When the work information is recorded in the NFC tag, not only forgery determination can be performed using the information of the NFC tag, but also during the exhibition, visitors can tag the NFC tag by using a device such as their smartphone. There is an additional advantage, such as to be able to confirm the work information.

Furthermore, the information recorded in the NFC tag may include the location and size of photographing the microstructure from the material 100, the size of the grid 300, and / or the size of each unit unit 301 included in the grid 300. It may also include additional information.

In one embodiment, the unique number for the electronic fingerprint of the material 100 is recorded in the material 100 itself. The unique number is recorded in a position that is not separable among the material 100, so that the unique number can always be found at the time of distribution of the work of art using the material 100. For example, in the case of a canvas, a unique number may be imprinted at a specific position in the wooden frame of the canvas rather than the part of the mineral. Alternatively, the artist or another person may write the unique number on the ore portion of the canvas as a paint or the like. For example, the artist may write a work on the front of the canvas, and a unique number may be written on the back of the canvas.

In addition, a plurality of locations for stamping or recording the unique number on the material 100 may be used so that the unique number can be grasped from another location even if the unique number at any one location is compromised. In addition, if all of the unique numbers in a plurality of locations are damaged, even if you do not perform a forgery identification process using the unique number unique number in that you can fully suspect that the unique number is damaged by the malicious purpose of someone It is advantageous to stamp or record in multiple locations.

According to the present embodiment, even if the NFC tag sealed on the material 100 is lost or removed for malicious purposes in the process of distributing the artwork using the material 100, the material 100 itself may be removed. By checking the information of the database 340 using the carved or written unique number can determine whether the forgery. A detailed forgery determination process will be described below.

Can be transmitted from the user device to the communication unit 33 of the electronic fingerprint management system 3 (S22). For example, the read information may be a user's identification number that is imprinted on the subject matter of the target artwork 200 and entered into a user device for transmission to the communication unit 33 after the user confirms it, or the subject artwork 200 ) May be information obtained by reading an NFC tag fixed to).

In the case of reading the NFC tag, the user may read information from the NFC tag using the user device 4 and transmit the read information from the user device 4 to the communication unit 33. However, this is merely an example, and the process of reading the NFC tag may be performed using a reading device (not shown) provided in the electronic fingerprint management system 3, in which case the communication unit 33 reads from the NFC tag. Information may be received from the reading device. Therefore, in this case, the steps S21 and S22 can be omitted.

The forgery determination unit 36 compares the information read from the NFC tag fixed to the material or the material of the art work 200 with the information registered in the database 340 of the fingerprint registration unit 34 (S23). The emotion for forgery determination may be made for each of a plurality of orders according to the type of information to be compared.

As the primary emotion, the forgery determination unit 36 may compare the unique number read from the NFC tag fixed to the material or the material of the art work 200 with the unique number registered in the database 340. For example, if the unique number read from the material or the NFC tag fixed to the material of the target artwork 200 is not registered in the database 340 of the electronic fingerprint management system 3, the target artwork 200 is It can be determined that it is likely to correspond to a forgery.

In the primary emotion, if the work information is recorded in the NFC tag and database 340 may be further utilized. For example, by comparing the unique number and the work information read from the NFC tag of the target art work 200 with the corresponding information of the database 340, the unique number read from the NFC tag is registered in the database 340, In this regard, when the work information registered in the database 340 is different from the information read from the NFC tag, or the work information read from the NFC tag is registered in the database 340, but is registered in the database 340 in relation thereto. If the unique number is different from the unique number read from the NFC tag, it can be determined that the target artwork 200 is likely to correspond to the forgery.

As the secondary emotion, the forgery determination unit 36 may compare the electronic fingerprint read from the NFC tag with the electronic fingerprint registered in the database 340. The process of comparing the electronic fingerprint is a process of decrypting the photographing position and size of the microstructure, which is encrypted and stored in the database 340, the size of the grid, the size of each unit unit of the grid, and comparing the electronic fingerprint using the same. Include. If the digital transformation information of the microstructure read out from the NFC tag of the target artwork 200 is different from the electronic fingerprint registered in the database 340, it may be determined that the target artwork 200 is likely to correspond to a fake. have.

In one embodiment, when there are a plurality of electronic fingerprints read from the NFC tag each obtained from a different area of the material, the plurality of electronic fingerprints read from the NFC tag is compared with the electronic fingerprint of the same area registered in the database 340, respectively For example, when any one of the plurality of electronic fingerprints read from the NFC tag is different from the electronic fingerprint in the same area registered in the database 340, the target artwork 200 may be determined to have a high probability. .

Next, the forgery determination unit 36 transmits the result of the above-described comparison to the user device 4 as information on whether the target art work 200 is forged or not (S24). Therefore, the user of the user device 4 can easily check whether the object art 200 forgery through the above process.

As part of the second emotional process, when the microstructured image as shown in FIGS. 4A to 4E is registered in the NFC tag and the database 340, the forgery discrimination unit 36 reads the microstructured image from the NFC tag. And by checking whether the microstructure image registered in the database 340 matches or not the forgery of the target artwork 200. The image matching process may be performed by image processing through a computer, and the microstructure image registered in the NFC tag and the database 340 may be a posterized image to easily perform the process. .

On the other hand, for additional emotions that do not depend on the electronic fingerprint of the NFC tag as the third emotion, in one embodiment the electronic fingerprint management system 3 further includes a photographing unit 31. The photographing unit 31 photographs the fine structure of the target artwork 200 (S25). The process of photographing the microstructure may be the same as the microstructure photographing step S11 of the embodiment shown in FIG. 2, and thus, detailed description thereof will be omitted.

Next, the forgery determination unit 36 may compare the microstructure photographed by the photographing unit 31 with an electronic fingerprint registered in the database 340 (S26). The comparison process may include converting the microstructure photographed by the photographing unit 31 into an electronic fingerprint and comparing the converted electronic fingerprint with the electronic fingerprint registered in the database 340. The third emotion is preferably performed by obtaining a plurality of electronic fingerprints for the entire area of the material used in the target artwork 200, but is not limited thereto.
