Description

Blockchain-based image management device and driving method of the device {Blockchain-based apparatus for Image Management and Driving Method Thereof}

The present invention relates to a blockchain-based image management device and a method of operating the device. More specifically, the present invention relates to a blockchain-based image management device and a method of operating the device. More specifically, when providing platform services based on occupations, hobbies, interests, sales, marketing, etc., photographic images of copyright holders are protected without permission. It relates to a blockchain-based image management device and a method of operating the device to prevent theft.

Recently, various platforms are being operated for jobs, hobbies, interests, sales, and marketing, and there are many cases where photo images are uploaded within those platforms for the community among members. However, when a specific member uploads a photo image to the platform, others may download the photo image or use it for personal purposes using screen capture methods.

For example, in the beauty industry such as hair, there are cases where a hair shop or hair designer styles a specific customer, takes photos for a portfolio, and uploads the photo images to the platform. These uploaded photo images are then shared with other hair salons. Not only do hair designers use it without permission, but there are also cases where someone else's styling is used for marketing purposes as if it were done for their own shop or by themselves.

Accordingly, there is an urgent need for a method to prevent unauthorized theft and use of existing technologies by others.

Meanwhile, blockchain is a data tamper-proofing technology that distributes and stores managed data in the form of a chain created based on the P2P (Peer to Peer) format instead of a centralized system. Since multiple blocks are stored in a chain format, it is called a blockchain and is connected sequentially over time. Blockchain is a distributed ledger structure, so everyone participating in the blockchain network owns the ledger for transactions, so when checking transaction details, the ledgers held by all users must be compared and confirmed. Even when attempting to add a block by making an additional transaction, the validity of the transaction must be verified by everyone participating in the blockchain network, thereby preventing fraudulent transactions.

In addition, existing centralized systems have a risk of hacking, but since blockchain stores data for all users, all users' transaction data must be attacked in order to perform forgery. Therefore, hacking is virtually impossible and transparency of transactions can be recognized. In addition, it is known to have the advantage of eliminating the cost of managing a central server because it does not require a central system.

Korean Patent Publication No. 10-2020-0018159 (2020.02.19) Korean Patent Publication No. 10-2021-0068929 (2021.06.10) Korean Patent Publication No. 10-2280736 (2021.07.16)

An embodiment of the present invention is a blockchain-based image management device and operation of the device to prevent unauthorized use of photo images of copyright holders when providing platform services with themes such as occupation, hobby, interest, sales, marketing, etc. The purpose is to provide a method.

A blockchain-based image management device according to an embodiment of the present invention includes a communication interface unit that receives data about a photographic image as a copyrighted work provided by a first user terminal device of the copyright holder, and a communication interface unit that receives data about the photographic image in a plurality of areas. After dividing, the divided images are distributed and stored by applying blockchain technology, and when preset conditions are met, the distributed and stored divided images are synthesized to create an original photo image and sent to the user's second user terminal. It includes a control unit that controls the communication interface unit to provide information to the device.

When displaying the pre-stored photo image on the screen of the first user terminal device or the second user terminal device, the control unit may display a lower-resolution image on the screen than the original photo image.

The control unit may automatically generate the same watermark on the divided images and store them in a distributed manner.

The control unit may notify the user to obtain approval from the copyright holder when the original photo image displayed on the screen of the second user terminal device is downloaded or screen captured.

The control unit may determine whether the copyright holder approves based on the preset conditions.

When the first user terminal device uploads a photo image to the storage unit, the control unit applies deep learning of artificial intelligence (AI) to analyze whether the photo image is identical to the photo image previously stored in the storage unit and reports the analysis result to the above. Notification may be made to the first user terminal device.

The control unit matches a keyword to the received photo image and stores it in the storage unit, and when a search is performed using a keyword in the first user terminal device, a plurality of images displayed on the screen as a search result are plagiarized. Alternatively, theft can be analyzed through deep learning.

In addition, a method of driving a blockchain-based image management device according to an embodiment of the present invention includes the steps of a communication interface unit receiving data about a photographic image as a copyrighted work provided by a first user terminal device of the copyright holder, and a control unit After dividing the received photographic image into a plurality of areas, the divided images are distributed and stored using blockchain technology, and when preset conditions are met, the distributed and stored divided images are synthesized to create an original photographic image. and controlling the communication interface unit to provide information to the user's second user terminal device.

According to an embodiment of the present invention, search efficiency can be further increased by searching for images stolen without permission through the unique pixel information of the divided image, and search is also possible even when the image is damaged and used by an unauthorized person using the image. can do.

Figure 3 is a block diagram illustrating the detailed structure of the blockchain-based image management device of Figure 1, and
FIG. 4 is a flowchart showing the operation process of the blockchain-based image management device of FIG. 1.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram illustrating an image management system according to an embodiment of the present invention, and FIG. 2 is a diagram illustrating a process of dividing a photographic image into tiles.

As shown in FIG. 1, the image management system 90 according to an embodiment of the present invention includes an author terminal device 100, a user terminal device 110, a communication network 120, and a blockchain-based image management device 130. ) and some or all of the third-party device 140.

Here, “including part or all” means that the image management system 90 is configured by omitting some components, such as the third-party device 140, or the image management system 90 is configured to form the blockchain-based image management device 130. It means that some or all of the elements can be integrated and configured into a network device (e.g., wireless exchange device, etc.) constituting the communication network 120, and it is explained as including all to facilitate a sufficient understanding of the invention. .

The author terminal device 100 includes a terminal device that connects to the service of the blockchain-based image management device 130 via the communication network 120 of FIG. 1 and uploads copyrighted works such as photo images. The author terminal device 100 includes various types of devices that can use a wired or wireless Internet environment, such as PC-based desktop computers and laptop computers, as well as mobile-based tablet PCs, smartphones, and wearable devices worn on the user's wrist. do. The author terminal device 100 is active in various fields such as occupations, hobbies, interests, sales and marketing, and uploads images or photos taken by the author online to a specific platform service. For example, recently, many platforms have been introduced where people can showcase their talents to consumers and receive compensation for it. Through these services, when using an image you have created yourself for promotional purposes, you can access the blockchain-based image management device 130 and provide copyrighted work of the photo or image.

Of course, the author terminal device 100 is, for example, in the case of a hair shop, a hair shop manager or designer takes a photo of the hair work that he or she directly presented to the customer, and the photo image is stored in the blockchain-based image management device 130. It can be sent to . These services may be provided in the form of a metaverse. Here, a photographic image is created by taking a photograph, but in the case of a graphic designer, an image can be created through an image creation operation without a separate photographing operation such as taking a photograph, so there will be no particular limitation to the terms photograph or image. However, since photographs can also be called images, they will be collectively referred to as images.

The user terminal device 110 is not significantly different from the author terminal device 100 in terms of device type. However, if the author terminal device 100 is intended to mean the terminal device of the copyright holder for an image work, the user terminal device 110 accesses the service of the blockchain-based image management device 130 of FIG. 1 to store the copyright holder's image. It refers to the terminal device of general users who view or view copyrighted works. The user terminal device 110 may also include various devices such as a PC-based terminal device or a mobile-based terminal device.

Above all, when the user terminal device 110 uses the service by registering as a member of a specific platform, unauthorized use of images provided on the service screen is not possible. In other words, if you want to download an image and there is approval from the author's terminal device 100 or if cost processing is required first, the image may be downloadable after cost processing. Above all, when performing an action such as screen capturing an image on the screen, the blockchain-based image management device 130 detects the user's action and then informs the user that unauthorized copying is not possible for protection of copyright, etc. Notification can be made to the terminal device 110. That is, it is displayed on the screen. For example, the blockchain-based image management device 130 requests service for a specific screen from the user terminal device 110 and then monitors whether the screen capture program is executed or the screen capture button on the keyboard is selected. Therefore, a guidance message can be notified based on this.

In addition, when the user terminal device 110 accesses the blockchain-based image management device 130 and uses the service, it provides a lower resolution image on the screen compared to the original image provided by the actual author terminal device 100. High resolution means that there are a large number of pixels in the specified image size, and low resolution means that there are fewer pixels in the same image size as above, or that the gray level of the pixel value of the pixel is lowered. In other words, in the case of color, colors can be expressed in 256 gradations, which means this. In embodiments of the present invention, the latter case is preferable.

The communication network 120 includes both wired and wireless communication networks. For example, a wired or wireless Internet network may be used or linked as the communication network 120. Here, the wired network includes an Internet network such as a cable network or public switched telephone network (PSTN), and the wireless communication network includes CDMA, WCDMA, GSM, Evolved Packet Core (EPC), Long Term Evolution (LTE), and Wibro networks. It is meant to include. Of course, the communication network 120 according to an embodiment of the present invention is not limited to this, and can be used in, for example, a cloud computing network in a cloud computing environment, a 5G network, etc. For example, if the communication network 120 is a wired communication network, the access point within the communication network 120 can connect to the telephone company's exchange office, etc., but in the case of a wireless communication network, it can connect to the SGSN or GGSN (Gateway GPRS Support Node) operated by the communication company to receive data. Data can be processed by connecting to various repeaters such as BTS (Base Transsive Station), NodeB, and e-NodeB.

Communication network 120 may include an access point. The access point here includes small base stations such as femto or pico base stations that are often installed in buildings. Femto or pico base stations are classified according to the maximum number of author terminal devices 100 or user terminal devices 110 that can be connected in the classification of small base stations. Of course, the access point may include a short-distance communication module for performing short-distance communication such as Zigbee and Wi-Fi with the author terminal device 100 or the user terminal device 110. Access points can use TCP/IP or RTSP (Real-Time Streaming Protocol) for wireless communication. Here, in addition to Wi-Fi, short-range communication can be performed using various standards such as Bluetooth, Zigbee, infrared, radio frequency (RF) such as Ultra High Frequency (UHF) and Very High Frequency (VHF), and ultra-wideband communication (UWB). Accordingly, the access point extracts the location of the data packet, specifies the best communication path for the extracted location, and forwards the data packet along the designated communication path to the next device, such as the blockchain-based image management device 130. You can. Access points can share multiple lines in a typical network environment and include, for example, routers, repeaters, and repeaters.

The blockchain-based image management device 130 provides various types of platform services related to occupation, hobbies, interests, sales, marketing, etc. Within the platform, photo images can be uploaded for the community among members. Of course, only the copyright holder is allowed to upload the image. In order to determine whether the copyright holder exists, the blockchain-based image management device 130 can check the copyright number provided by the Copyright Committee when uploading a work from the author terminal device 100, but it is stored in the DB 130a. You can also check for copying or plagiarism by comparing image pixel values with existing works. Of course, for this operation, the blockchain-based image management device 130 can run a deep learning program of artificial intelligence (AI), and share the DB in partnership with a server operated by the Copyright Commission, etc. to secure image data through this. It is possible to determine whether there is copying or plagiarism.

The blockchain-based image management device 130 according to an embodiment of the present invention executes a program for image capture on the user terminal device 110 to prevent unauthorized use of the author's photos or directly created graphic images, etc. , or whether the screen capture button is selected on the keyboard. In addition to these operations, the blockchain-based image management device 130 first divides the image into tiles when uploading an image to the same platform as the blockchain-based image management device 130 of FIG. The divided images are distributed and stored using blockchain technology so that the original photo can be downloaded only under certain conditions. As mentioned earlier, the resolution of the image displayed on the actual platform is displayed at a lower level and a watermark is automatically created. After doing so, it is exposed on the platform to prevent unauthorized theft and use by others.

In addition, the blockchain-based image management device 130 not only minimizes post-dispute disputes by specifying the portrait rights holder's permission and the copyright holder (e.g., joint/single) for photo images uploaded to the platform, but also ensures that photo images uploaded to the platform are uploaded to the platform. If the city approves commercial use, the third party ensures that a certain fee is paid to the portrait and copyright holder of the photo. Furthermore, the blockchain-based image management device 130 automatically searches for images uploaded by members on the platform for identical images within the server using deep learning, and notifies the member who uploaded the image when the same image is searched. , In cases other than the platform, when a member requests a keyword, the image exposed on the web page searched through the keyword is searched for image theft using deep learning.

To summarize, the blockchain-based image management device 130 uses blockchain technology by registering as a member, uploading management images (e.g., selecting permission for paid/free use by a third party), and dividing the original image that can be used by a third party. Apply distributed storage, lower the resolution of images for exposure and display a watermark (e.g., copyright holder and model rights holder), respond to a third party's request to use the original image, and use deep learning to detect unauthorized use of the original image within the platform in real time. It performs actions such as image search, combining original images using blockchain technology, notifying members when searching for the same image, approving/downloading transactions, stopping exposure of the image when a member requests sanctions, and paying platform points to the original author. Here, “synthesizing original images using blockchain technology” may mean loading and compositing split images distributed and stored using blockchain technology.

The blockchain-based image management device 130 according to an embodiment of the present invention verifies whether the image provided by the author terminal device 100 is the original author. To this end, the copyright number assigned by the Copyright Committee is confirmed, or a verification operation is performed using images previously stored in the DB 130a. For example, when the result of comparing the pixel value of the image appears to be higher than the standard value, the author can inform the terminal device 100 and inquire about copying or plagiarism and receive a response.

If verification of the original author of the image is completed through this process, the blockchain-based image management device 130 performs operations to prevent copying or unauthorized use. As shown in FIG. 2, the image of the first captured or produced unit frame can be restored by decoding the encoded and transmitted image. When restored in this way, the blockchain-based image management device 130 can generate a low-resolution converted image for the corresponding image. Low-resolution images are used when providing a service screen to the user terminal device 110. Additionally, in the case of the original image, it is divided and stored in tile form. Here, tile-type division is different from division in macroblock units when encoding. As can be seen in (b) of FIG. 2, the sizes of tiles may vary. In other words, macroblocks are standardized and the size of the division must be constant, but our tile-type division does not have a specified size like a macroblock, as the division is based on the feature points of the original image. In other words, it can be changed as much as desired depending on the intention of the system designer. In addition, in segmentation, pixel analysis can be performed by dividing the image in a square shape, but it is also possible to extract pixels in a specific area based on the boundary line from a unit video frame and analyze them, so there are special restrictions on the shape of segmentation. I won't do it. Figure 2 can be viewed as a tile-type division by extracting pixels from a specific area. However, embodiments of the present invention will not be particularly limited to such forms.

The blockchain-based image management device 130 can assign a watermark to an original image divided on a tile basis and can assign the same watermark to a plurality of tile images. Although the watermark is already a known matter, there may be a difference in that the watermark may be given in the form of a code such as a tile image. Additionally, tile images are distributed and stored based on blockchain. The key to blockchain technology is to store data by decentralizing it, as centralized servers are vulnerable to attacks such as hacking. In addition, the main content of the technology is to ensure that when there is a modification of distributedly stored data, that is, when there is a transaction, the previously stored ledger, that is, image data, is modified when approved by each distributed device. In the embodiment of the present invention, since segmented image data is stored from each device, an approval procedure may be used when loading for compositing. At this time, the approval process can be performed by providing encrypted encryption information or watermark information.

Of course, blockchain encryption technology deviates from the existing method of creating a single piece of data and storing it on a central server to prevent hacking through a security program, restoring one piece of data and storing the same data on multiple servers in the form of a block to compare it with the original. It is a technology that maintains security in the form of contrast. The creation and security of data is accomplished quickly, and encrypted currency (e.g. virtual assets) is created based on this. When encrypted data is converted into monetary value, the movement of data becomes the same as the monetary flow. In the case of quantity or amount, it is determined by combining data in block form, and the initial creation value of the encrypted data and the result when holding it are calculated using an operator called a hash function. is compared through. Blockchain encryption data is divided into blocks related to encryption and nodes that preserve data. A node can simply be said to be the participant's server. If you want to hack a blockchain cryptocurrency, you must hack all of the participants' computers or servers, but even if you hack it, it cannot be used if the original blockchain form (e.g. Genesis block) cannot be restored. As mentioned above, the embodiment of the present invention can be viewed as an application of the existing blockchain form.

In this way, the blockchain-based image management device 130 divides original images that can be used by third parties and stores them distributedly using blockchain technology. Of course, distributed storage can be done with a third-party device 140, etc., and distributed storage and blockchain technology can be implemented by linking with the author's terminal device 100 or a server operated by the Copyright Commission. The original image is segmented, and a unique pixel encryption operation is performed for each segmented image. For example, images that are divided into four have different pixel values. Therefore, encryption and decryption can be performed using the same encryption key and the same decryption key. Encrypted tiles, or split images, are distributed and stored in a blockchain format. Additionally, upon user request, split images are synthesized and provided to users with permission to use them. A typical example is when there is a request to download the original image. In this case, the distributedly stored split images can be decoded and synthesized. When compositing the original image, it includes unique pixel information of the divided image. Here, unique pixel information may be color information or grayscale information. Alternatively, it may be information in the form of segmented feature point information or shape. In addition, the blockchain-based image management device 130 allows searches to be made using unique pixel information when searching for unauthorized images. Encryption and decryption involve converting and encrypting by applying a specific function value and then inverting the encrypted value to find the original pixel value. This is obvious to those skilled in the art, so further explanation will be omitted.

In this way, search efficiency can be increased by searching for images that have been stolen without permission through the unique pixel information of the divided image, and search may also be possible when an image is damaged and used by someone who uses it without permission.

The third-party device 140 is the computer of the operator who operates the blockchain-based image management device 130, and the computer or server of the developer who produces and provides the service program for the blockchain-based image management device 130. Includes devices. Alternatively, it may include devices such as a copyrighted work server or DB operated by the Copyright Committee. For example, in the case of an administrator device that manages a service, it is possible to check the corresponding notices on the user terminal device 110, etc. by accessing the administrator web address and registering notices provided on the service screen.

Figure 3 is a block diagram illustrating the detailed structure of the blockchain-based image management device of Figure 1.

As shown in FIG. 3, the blockchain-based image management device 130 according to an embodiment of the present invention includes a communication interface unit 300, a control unit 310, an image management unit 320, and a storage unit 330. Includes some or all of it.

Here, “including part or all” means that the blockchain-based image management device 130 is configured by omitting some components, such as the storage unit 330, or that some components, such as the image management unit 320, are omitted. This means that it can be configured by being integrated with other components such as the control unit 310, and is described as all-inclusive to facilitate a sufficient understanding of the invention.

The communication interface unit 300 communicates with the author terminal device 100, the user terminal device 110, and the third-party device 140 respectively via the communication network 120 of FIG. 1, and in the process of performing communication, It performs operations such as modulation/demodulation, muxing/demuxing, encoding/decoding, and resolution conversion. Since this is obvious to those skilled in the art, further explanation is omitted.

However, the encoding/decoding here is different from dividing and encrypting the image restored in tile form according to the embodiment of the present invention, and decoding and compositing it at the request of a third party, and converting the original image to low resolution to display the service screen. It is also distinguished from what is provided. Additionally, the above resolution conversion means reprocessing pixel values according to the size of the 7-inch or 10-inch screen of the user terminal device 110. For example, if 8-bit data is processed to represent a pixel, it is typically processed as 6-bit data. On the other hand, converting the resolution of an original image, which is a copyrighted work according to an embodiment of the present invention, can be understood as converting the grayscale level of a pixel.

When the author terminal device 100 accesses the service of the blockchain-based image management device 130 and uploads an image such as a photo, the communication interface unit 300 can receive the image and transmit it to the control unit 310. . In addition, when a service request is made from the user terminal device 110, a service screen can be provided under the control of the control unit 310. For example, in the case of a platform that showcases talent, images related to the activities of donors who donate talent are displayed. The service screen is provided as a low-resolution image.

In addition, the communication interface unit 300 determines whether approval from the author terminal device 100 of the original author is requested when accessing the service from a third party's user terminal device 110 and requesting a download of a specific image on the screen. The original image is provided based on the confirmation result of the user's payment.

The control unit 310 is responsible for the overall control operation of the communication interface unit 300, image management unit 320, and storage unit 330 of FIG. 3. The control unit 310 can typically temporarily store the image provided by the author terminal device 100 of FIG. 1 in the storage unit 330 through the communication interface unit 300, retrieve it, and provide it to the image management unit 320. there is. Additionally, the control unit 310 controls the communication interface unit 300 to receive the image processing results of the image management unit 320 and systematically classify and store them in the DB 130a of FIG. 1 . Here, the image processing results are used, for example, to create a segmented image by dividing the original image into tiles for distributed storage by applying blockchain technology, or to encrypt the segmented image, and to provide a service screen as a low-resolution image. This means creating a low-resolution image by lowering the gradation of the pixel values of the original image.

When the user terminal device 110 requests the download of a specific image on the service screen, for example, a photo image worked by a hair designer at a hair shop, the control unit 310 performs a compositing operation of images divided into tiles to provide the original image. Perform. Since the information of the distributed storage device is pre-stored, each segmented image is received from the device and restored through decryption through the image management unit 320. Then, the communication interface unit 300 is controlled to synthesize the plurality of restored split images and provide them to the user terminal device 110. For example, the split image may have matching sequential numbers such as 1, 2, 3, 4, etc., and the watermark information can be checked to confirm whether it is a split image of the original original image. Through this, the synthesized image can be converted into data packets and provided to the user terminal device 110.

The image management unit 320 performs operations to prevent images provided as service screens in the platform service from being copied or stolen without permission. As mentioned above, the image management unit 320 can convert the image to black by detecting whether a screen capture program is running, and can also detect whether the screen capture button is selected on the keyboard to convert the image to be captured into black, etc. By processing it, you can fundamentally prevent theft. In this way, the image management unit 320 can monitor illegal activities of users.

In addition, the image management unit 320 can apply blockchain technology to distribute and store images to prevent hacking of copyrighted images, etc., and in the process, divide the original image into a plurality of areas. As mentioned earlier, the tile-based segmentation here is distinct from the macroblock for encoding. Hacking can also be fundamentally prevented by periodically changing the tile-based division method. For example, when dividing the original image into four, the image management unit 320 encrypts the split image, that is, encrypts the pixel values of the split image by applying an encryption code, and stores them distributedly in the form of inserting a watermark code. You can. Of course, in this process, it can also be processed by assigning sequential numbers to the divided images.

In this state, when a download request for a specific image is made from a third party's user terminal device 110 through a legal route (e.g., approval of the copyright holder or cost processing, etc.), distribution is made based on pre-stored device identification information, etc. The stored segmented images can be retrieved and decoded, and the decoded segmented images can be synthesized sequentially, processed into data packets, and then provided to the user terminal device 110. In this process, the image management unit 320 can check the watermark code to determine whether it has been divided from the same original image. Of course, the watermark is provided along with the download image while providing the platform service to prevent copying, but in the embodiment of the present invention, it will not be particularly limited to any one form. For example, in an embodiment of the present invention, a watermark can be used as an approval means for consensus in a blockchain.

In addition, when an image upload request is made from the author's terminal device 100, etc., the image management unit 320 can search for the same image to check whether the image has been copied or plagiarized, and for this purpose, pixel values are compared. A search operation may be performed in the form of a search operation, or a search operation may be performed in the form of comparing feature points. Additionally, in order to increase the accuracy of comparison, search operations can be performed through learning by applying an artificial intelligence deep learning program. For example, when a user enters a search term, images can be exposed on the website based on the search term, and the exposed images can be compared and the results can be notified to the author terminal device 100. Through this, the user of the author's terminal device 100, that is, the author, may be able to make a final determination as to whether or not the image has been stolen.

The storage unit 330 temporarily stores various types of data or information under the control of the control unit 310 and then outputs them. Data may refer to pixel data of an image, and information may refer to simple control commands. However, since they are often used interchangeably in the industry, there will be no particular limitation on the concept of the terms. For example, when a photo image, i.e., pixel data of the image, is provided, the control unit 310 may temporarily store it in the storage unit 330, retrieve it, and provide it to the image management unit 320.

In addition to the above, the communication interface unit 300, control unit 310, image management unit 320, and storage unit 330 of FIG. 3 can perform various operations, and other details have been sufficiently explained previously. I would like to replace it with .

The communication interface unit 300, control unit 310, image management unit 320, and storage unit 330 of FIG. 3 according to an embodiment of the present invention are composed of hardware modules that are physically separated from each other, but each module has an internal Software for performing the above operations may be stored and executed. However, the software is a set of software modules, and each module can be formed of hardware, so there will be no particular limitation on the configuration of software or hardware. For example, the storage unit 330 may be hardware, such as storage or memory. However, since it is possible to store information through software (repository), the above content will not be specifically limited.

Meanwhile, as another embodiment of the present invention, the control unit 310 may include a CPU and memory, and may be formed as a single chip. The CPU includes a control circuit, an arithmetic unit (ALU), an instruction interpretation unit, and a registry, and the memory may include RAM. The control circuit performs control operations, the operation unit performs operations on binary bit information, and the command interpretation unit includes an interpreter or compiler, which can convert high-level language into machine language and machine language into high-level language. , the registry may be involved in software data storage. According to the above configuration, for example, at the beginning of the operation of the blockchain-based image management device 130, the program stored in the image management unit 320 is copied, loaded into memory, that is, RAM, and then executed to process data operations. Speed can be increased quickly.

FIG. 4 is a flowchart showing the operation process of the blockchain-based image management device of FIG. 1.

Referring to FIG. 4 together with FIG. 1 for convenience of explanation, the blockchain-based image management device 130 according to an embodiment of the present invention receives data of a photo image as a copyrighted work provided by the first user terminal device of the copyright holder. (S400). Here, the photographic image may also include an image produced by a designer, etc. using a graphic program rather than a photo shoot.
