In the description of the embodiment, if it is determined that a detailed description of a related known technology may unnecessarily obscure the gist of the embodiment, the detailed description thereof will be omitted.

The embodiments may be implemented in various types of products, such as personal computers, laptop computers, tablet computers, smart phones, televisions, smart home appliances, intelligent cars, kiosks, wearable devices, and the like.

1 is a diagram schematically showing the configuration of a system according to an embodiment.

1, the system according to an embodiment includes a plurality of creator terminals (2), a buyer terminal (4), a seller terminal (3), and one or more management servers (1), a database server (6) and a file server ( 5), and may be connected to a pre-established Main Net.

The creator terminal (2), the buyer terminal (4), and the seller terminal (3) may mean smart devices, PCs, etc. owned by the creator, the buyer and the seller, respectively, and any one terminal is the creator terminal (2), the buyer terminal (4) and may perform one or more roles/functions of the seller terminal (3). For example, a creator uses his/her smart device as a creator terminal (2) to NFT his/her content, and later uses the smart device as a seller terminal (3) to sell his/her own NFT. It can also be used as the purchaser's terminal 4 to purchase other NFTs thereafter.

In one embodiment, the mainnet may correspond to an Ethereum network.

According to one embodiment, the management server (1) receiving a request for registration of the original file of the content from the creator terminal (2) (S100); may include.

The creator uploads the original file of a creation, such as an image or article, from an app installed on his/her creator terminal (2) or a web page/web app accessed from a web browser, and sends a registration request message to the management server (1) ) can be sent.

The registration request message may be transmitted/received by a GET method or a POST method in the HTTP/HTTPS protocol of the web-based application.

Assuming that the registration request has been successfully approved and processed, the following steps will be described. A case in which the registration request is rejected due to abnormality, such as that the content requested for registration is the same content that overlaps with the existing content, will be described separately later.

Contents such as text articles are basically small in capacity and can be stored in the database (database server) or directly in the management server 1, but since the content such as images or videos has a relatively large capacity, the database or management server ( If it is stored in 1), problems may occur in the maintenance/repair process.

In addition, if you want to store the original file in the block chain, a lot of time and cost (gas cost) is incurred for storage, so the file server (5), management server (1), and database server (6) are operated individually as described above. It is preferable to connect to the mainnet.

Therefore, according to the step (S200) of storing the original file of the content received by the management server 1 in the file server 5; ) is preferably stored in

The metadata for the original file of the content stored in the file server 5 and/or the path in the file server 5 may be used as a 'unique identifier of the content' to be described later.

generating, by the management server 1, a non-fungible token (NFT) in which the unique identifier of the content and the first unique information of the creator are recorded on the block chain using a smart contract (S300); By including the location of the original file of the content and the creator's unique information (the creator's first unique information; identification information such as the creator's name, email, unique code (ID), and electronic signature) in the non-fungible token, the content When it is used as an article and posted, it can prove who the producer of the content is.

Since the creator information for each content is recorded in the distributed ledger as described above and cannot be forged or altered, consumers who encounter content such as articles can trust the content.

Hereinafter, a method of trading non-fungible tokens registered in the manner described above will be described. The management server 1 may perform the non-fungible token registration steps as described above, and independently and simultaneously perform the non-fungible token sale steps to be described later.

Step (S400) of the management server 1 receiving a purchase request for some of a plurality of non-fungible tokens from the purchaser terminal 4; One or more selected by the purchaser terminal 4 in the non-fungible token content trading platform With respect to the content, it is transmitted from the purchaser terminal 4 to the management server 1 when the purchase request button is operated to purchase the non-fungible token corresponding to each content.

In the above description, 'some of a plurality of non-fungible tokens' means any one or more of a plurality of non-fungible tokens registered by a plurality of creators. Accordingly, the purchaser may request to purchase one or more non-fungible tokens one by one or at a time.

In accordance with the step (S500) of the management server 1 transmitting the purchase request to the seller terminal 3; .

It is confirmed that a predetermined push notification is generated in the seller terminal 3 and a purchase request message for the non-fungible token owned by the seller has been received.

The seller may check the bid price recorded in the purchase request message, and may approve or reject the purchase request based on this.

For non-fungible tokens that are newly created and not transacted (traded) to other users, the creator terminal 2 performs the function of the seller terminal 3 . After the creator sells non-fungible tokens to other users, the buyer of the non-fungible tokens acts as a seller to other users.

The step (S600) of the management server 1 receiving whether or not to approve the purchase request (including an approval decision and approval rejection) from the seller terminal 3; When the seller approves the purchase request, the corresponding It may include the process of determining whether a transaction is appropriate and processing the transaction.

When the approval decision is received in the management server (1), the step of transmitting (Transaction) the non-fungible token to the address of the purchaser (S700); and recording in the block chain the history of the non-fungible token being transmitted from the seller's address to the buyer's address (S800); in the 'address' may mean an electronic wallet address.

The above transaction process may be performed by the exchange while the non-fungible token is listed on the exchange server.

Hereinafter, a process in which content created or traded with non-fungible tokens is posted on a media platform or SNS will be described.

In the step (S900) of the management server 1 receiving a request for posting for the content from the publisher terminal, an owner who currently possesses a non-fungible token, such as a creator or a purchaser, or a non-owner who wants to publish the content owns his/her terminal This is performed when the register/publish button is operated by attaching a predetermined image or article (text, etc.) to register an article, post, image, etc. through .

In this case, in order for the non-owner to post other people's content, the owner must set the right to allow others to freely or with permission to post the content.

When the owner posts content, the revenue according to the number of views, etc. can be directly distributed to the owner. Accordingly, a portion of the revenue may also be distributed to non-owners who posted the content.

Verifying whether the second unique information of the content creator included in the posting request is the same as the first unique information of the creator recorded in the non-fungible token of the content (S1000); In order to improve the reliability of the content by proving who the creator (producer; creator) of the content is in the content of compared with the second unique information of

According to the step (S1100) of approving the posting request in which the creator's second unique information is the same as the creator's first unique information in the verification step (S1100); By allowing content to be published, you can ensure the reliability of the content.

A predetermined advertisement revenue identifier is assigned to the posted content, and information such as the number of views of the content, the number of clicks on advertisements placed around the content, and whether or not the advertiser's sales are generated according to the advertisement can be recorded for each advertisement revenue identifier. have.

According to the recorded advertisement revenue information, the advertisement revenue settlement step may be performed every predetermined period.

According to the advertising revenue settlement stage, a portion of the generated revenue is deducted from the media platform as a commission, and the remaining revenue is distributed to content owners and content publishers.

According to these revenue-sharing rules, production, reporting, and posting of highly ripple and reliable content can be promoted.

Also, the content may include one or more of: an image file and an article. It may be an article composed of text (posts, etc.) or an image (photo, video, etc.), or it may be an article that includes both text and images.

Receiving the posting request (S900) includes: If the content includes an article, checking whether an image is attached to the inside of the article (S910); Perform validation steps.

When the unique identifier of the image is attached to the inside of the article (S921), ① comparing the image and ② the image corresponding to the unique identifier of the image, verifying whether the two images are the same image (S922) ; to verify the validity of the image.

If an image is attached within the article, but the unique identifier of the image is different from the information recorded in the non-fungible token, it can be viewed as an attempt to produce fake news by manipulating the photos inside the article, so you can reject it and prevent registration/posting. can If such wrong attempts are repeated, after recording the log, the administrator can determine whether the attempt was an attempt to produce fake news and block the user from the media platform, etc.

When the two images are verified as the same image (when the validity of the image in the article is verified), authorizing the publication of the article (S923); may include.

And, the step of receiving the posting request (S900) is: when the unique identifier of the image is not attached to the inside of the article, the step of requesting registration of the image original file to the management server 1 (S931); If the image attached to the article has not been previously created as a non-fungible token through the can be included

At this time, the creator terminal 2 processes the non-fungible token generation process by designating the same device as the creator terminal 2 of the article.

When the non-replaceable token generation process of the image attached to the article is normally processed, parsing and returning a unique identifier for the image (S932); is performed.

Thereafter, a unique identifier for the returned image is automatically attached to the inside of the article, and the step of authorizing the publication of the article (S933); is performed.

In the process of generating/registering/posting an article with a number of images as non-fungible tokens, user convenience by automatically performing the process of generating non-fungible tokens and registering/posting content for images included in the article as described above can increase

In the case of articles containing images, it is possible to allow the ownership of the images and articles to be traded individually, but it is also possible to allow only the images and articles to be traded in bulk according to the policy of the media platform.

The step (S100) of the management server 1 receiving the registration request of the original file of the content from the creator terminal 2 is: When the content is an image file (hereinafter referred to as a 'first image file'): the calculating a first histogram of the first image file (S110); Receiving a second histogram of the image files stored in the database from the database server 6 (S120); comparing the first histogram with the second histogram and confirming whether there is an image file (hereinafter, referred to as a 'second image file') having a degree of similarity greater than or equal to a predetermined value in the database (S130); and rejecting the registration request of the first image file when there is an image file having a degree of similarity greater than or equal to a predetermined value in the database (S140).

Due to the processing load/processing speed, which is one of the limitations of the blockchain, it is difficult to check the overlap of images in the image non-replaceable tokenization system as in one embodiment in a general method.

Therefore, the histogram of non-fungible tokenized images is separately stored in the database server 6 every time a block is created, and when a non-fungible token generation request (registration request of the original file) is received for the image, it is newly registered as above. The same image can be detected by comparing the histogram of the desired image with the histograms in the database.

A predetermined artificial intelligence (artificial neural network) model and/or algorithm may be applied to the determination of similarity between images.

An artificial intelligence (AI) system is a computer system that implements human-level intelligence, and unlike the existing rule-based smart system, the machine learns and makes decisions on its own. The more the AI system is used, the better the recognition rate and the more accurate understanding of user preferences, and the existing rule-based smart systems are gradually being replaced by deep learning-based AI systems.

Artificial intelligence technology consists of machine learning and element technologies using machine learning. Machine learning is an algorithm technology that categorizes/learns characteristics of input data by itself, and element technology uses machine learning algorithms such as deep learning to simulate functions such as cognition and judgment of the human brain. It consists of technical fields such as understanding, reasoning/prediction, knowledge expression, and motion control.

The various fields where artificial intelligence technology is applied are as follows. Linguistic understanding is a technology for recognizing and applying/processing human language/text, and includes natural language processing, machine translation, dialogue system, question and answer, and speech recognition/synthesis. Visual understanding is a technology for recognizing and processing objects like human vision, and includes object recognition, object tracking, image search, human recognition, scene understanding, spatial understanding, image improvement, and the like. Inferential prediction is a technology for logically reasoning and predicting by judging information, and includes knowledge/probability-based reasoning, optimization prediction, preference-based planning, and recommendation. Knowledge expression is a technology that automatically processes human experience information into knowledge data, and includes knowledge construction (data generation/classification) and knowledge management (data utilization). Motion control is a technology for controlling autonomous driving of a vehicle and movement of a robot, and includes motion control (navigation, collision, driving), manipulation control (action control), and the like.

In general, in order to apply the machine learning algorithm to real life, learning is performed in the Trial and Error method due to the characteristics of the basic methodology of machine learning. In particular, deep learning requires hundreds of thousands of iterations. It is impossible to execute this in the actual physical external environment, so instead, the actual physical external environment is implemented on a computer and learning is performed through simulation.

In addition, receiving the operating system information of the firewall policy server and the network setting information of the firewall policy server from the firewall policy server connected to the management server (1) through an internal network; analyzing a network connection state of the firewall policy server based on the operating system information of the firewall policy server and network setting information of the firewall policy server; applying the analysis result of the network connection state of the firewall policy server to the artificial neural network in the management server 1, and selecting a firewall policy suitable for the firewall policy server based on the output of the artificial neural network; when a first policy is selected as a firewall policy suitable for the firewall policy server, checking whether the first policy is included in the firewall policy of the firewall policy server; if it is confirmed that the first policy is not included in the firewall policy of the firewall policy server, adding and registering the first policy to the firewall policy of the firewall policy server; and when the first policy is additionally registered in the firewall policy of the firewall policy server, a setting change command for the firewall policy of the firewall policy server is transmitted to the firewall policy server, so that the first policy is applied to the firewall policy server. and controlling to be set as a firewall policy, and after controlling so that the first policy is set as the firewall policy of the firewall policy server, the first policy and the second policy are registered in the firewall policy of the firewall policy server if it is, checking a first list that is a list of IP addresses allowed to connect through the first policy and a second list that is a list of IP addresses that are allowed to connect through the second policy; As a result of comparing the first list and the second list, if it is confirmed that the first list has a wider allowable range than the second list, the priority of the first policy is set as the first priority, and the second policy setting the priority of the to second priority; As a result of comparing the first list and the second list, if it is confirmed that the first list has a narrower allowable range than the second list, the priority of the first policy is set to the second priority, and the second policy setting the priority of As a result of comparing the first list and the second list, if it is confirmed that the allowable ranges of the first list and the second list are the same, the third list of IP addresses whose connection is blocked through the first policy checking the list and a fourth list that is a list of IP addresses whose connection is blocked through the second policy; As a result of comparing the third list and the fourth list, if it is confirmed that the third list has a narrower blocking range than the fourth list, the priority of the first policy is set as the first priority, and the second policy setting the priority of the to second priority; and when it is confirmed that the third list has a wider blocking range than the fourth list as a result of comparing the third list and the fourth list, the priority of the first policy is set to the second priority, and the second The step of setting the priority of the policy to the first priority; further comprising, the management server 1 can control the policy setting of the host firewall based on artificial intelligence.

Each of the management server 1, the firewall policy server, the database server 6 and the file server 5 can generate system data (CPU, memory, disk, disk input/output, and network traffic) and system log data. have.

In the server, an agent including a command in which a policy setting control method of an AI-based host firewall is implemented may be installed. Accordingly, the system may set the host firewall policy through the agent installed in the firewall policy server, or may set the host firewall policy through the agent installed in the management server 1 .

The firewall policy server is connected to the management server 1 through an internal network and can control the operation of each host as a main server connected to the outside via an external network. In this case, a host firewall is configured in a host connected through an internal network, and a network firewall is configured in a firewall policy server connected through an external network.

That is, the system may provide a guide so that the firewall policy can be configured in the management server 1 according to the type of network (TCP port, etc.). In this case, a template for setting the firewall policy may be automatically provided, and a default value for the firewall policy may be set.

In addition, the system can detect an attack presumed to be an attack based on deep learning of artificial intelligence, and recommend a blocking policy or provide a guide.
