Embodiments of the invention are described in detail below on the basis of exemplary drawings. It should be noted that, in assigning reference numerals to elements in each figure, as much as possible, identical elements have identical numerals, even if they appear on other drawings. In addition, in describing the embodiments of the present invention, if it is determined that a specific description of related known configurations or functions hinders the understanding of the embodiments of the present invention, the detailed description thereof will be omitted. .

FIG. 1 is a configuration diagram of a system for providing user-customized advertisements in a metaverse space using blockchain according to an embodiment of the present invention, and FIG. 2 is a configuration block diagram showing the operation of the system in FIG.

Referring to FIGS. 1 and 2, the user customized advertisement providing system in the Metaverse space using blockchain according to the preferred embodiment of the present invention includes a user terminal 110, a first communication network 120, a management server 130, a database (DB ) 140 , a metaverse server 150 , an advertisement server 160 , a second communication network 170 and an advertiser terminal 180 .

At this time, in the present embodiment, the user terminal 110, the management server 130, the metaverse server 150, and the advertisement server 160 can be configured to form the public consensus network 10, which is a public blockchain network, and the advertisement server 160 and the advertiser terminal 180 can be configured to form a private consensus network 20 of a private blockchain network.

The user terminal 110 can use the Metaverse space by connecting to the Metaverse server 150 through the first communication network 120, and can use various contents provided in the Metaverse space.

For example, the user can create his/her own avatar through the user terminal 110, set the avatar to act in the Metaverse space, and use the virtual reality content provided in the Metaverse space.

Accordingly, the user terminal 110 can receive commands from the user and display progress of the Metaverse space and various contents provided in the Metaverse space.

The user terminal 110 is a portable information communication device capable of changing and expanding functions through an application program, and typically includes a smart phone and a smart pad. be able to. Other examples include a personal computer (PC), a notebook computer, and the like.

The user terminal 110 is capable of wireless Internet connection using various web browsers, and can download and install application programs desired by the user.

When the user terminal 110 of this embodiment is a smart phone, it can also function as a mobile communication terminal, and various functions such as a camera and voice recognition can be added.

An application program for receiving advertisements in the Metaverse space can be installed on the user terminal 110 . Such application programs can be downloaded and installed from the Internet, an application store, or the management server 130, for example.

The user terminal 110 can generate a user block and record user information, including a user's unique identification (ID), in the user block. Such user blocks can be authenticated by the management server 130 and distributed and stored after agreement within the public consensus network 10 .

The user can connect to the management server 130 using the user terminal 110 to request and issue a transaction certificate and a registration certificate and store them in the electronic wallet. At this time, the management server 130 may be operated together with the metaverse server 150, or may be operated by a separate operator.

Metaverse servers 150 and ad servers 160 can be authenticated through management server 130 to participate in public consensus network 10 .

In addition, the user terminal 110 measures its position using the GPS module installed therein, and records its ID, time information and position information in the user block in real time or at preset intervals. be able to.

The first communication network 120 can handle wired and wireless communication between the user terminal 110, the management server 130, the database (DB) 140, the metaverse server 150, and the advertisement server 160, and the second communication network 170 can handle the advertisement server. Wired and wireless communications between 160 and advertiser terminal 180 can be handled. The first and second communication networks 120 and 170 may include wired/wireless communication networks such as 3G, 4G, 5G, and Ethernet, and local area networks such as WIFI, BLE, Zigbee, and NFC.

The management server 130 may analyze the time information and location information according to the movement pattern of the user terminal 110 using the information recorded in the user block to extract the user's field of interest.

At this time, the time information and the location information may include information about when and where the user has moved and how long the user has stayed.

The user's field of interest can be extracted based on the time information and location information of the user terminal 110 . Specifically, the time and location of movement of the user terminal 110 may be checked for a certain period of time to create statistical information on movement patterns. Such statistical information can be used to identify places that are frequently visited or stayed longer.

For example, as a result of grasping the movement pattern of the user for three months, if the user stays at the soccer field for five hours in the morning every Sunday, the management server 130 may determine the location based on the location information transmitted from the user terminal 110 . It can be confirmed that the location is a specific soccer field, and it is possible to extract that the user has a lot of interest in soccer based on the time information of staying at the soccer field. Such spatial information can include GPS coordinates.

In this way, the management server 130 sets a field corresponding to a specific position as a field of interest when the user terminal 110 remains at a specific position for a set time or longer based on the time information and position information of the user terminal 110 . can do.

Therefore, the management server 130 may determine that the user's field of interest is soccer in the above example, and may additionally record such user's field of interest in the user block. User blocks additionally recorded in this way can also be distributed and stored through consensus within the public consensus network 10 .

Advertisement server 160 may then provide advertisements corresponding to the user's areas of interest. For example, if you are the example user, you may be served advertisements related to the soccer field.

In another embodiment, the management server 130 may set, as a field of interest, a location that remains for a certain percentage of time or more within a set period based on the time information and location information of the user terminal 110 . . For example, soccer may be set as an area of interest if the user has spent more than 30 hours on the soccer field during a month.

Also, it is possible to subdivide the time spent and distinguish the grades of the fields of interest. In other words, if the staying time is longer than or equal to the first set time, the field of interest is set to be grade 1, and if the staying time is longer than or equal to the first set time and less than the first set time, the field of interest is set to be grade 2. can do.

For example, if you spent 50 hours at the soccer field and 30 hours at the golf course during a month, soccer is set as the highest interest area (1st grade), and golf is set as the next highest interest area (2nd grade). ) can be set as Such interest grading can affect advertising time in the future. A 1st grade can have relatively longer advertising time than a 2nd grade.

In another embodiment, the management server 130 may set the field corresponding to the specific position as the field of interest when the number of visits to the specific position during the set time is equal to or greater than a reference value. can. In other words, when the number of visits is large, it can be determined that there is a high degree of interest in the visited position, and the field corresponding to the visited position can be set as the field of interest.

For example, if the number of visits to mountains in a month is 10 or more, which is a predetermined reference value, mountaineering can be set as a new field of interest. This allows the user to receive user-customized advertisements for mountain climbing. Advertisements for mountaineering can be mountaineering clothing, shoes, accessories, and so on.

In addition, the management server 130 can generate the user's location information as spatial data using a Geographic Information System (GIS), and apply this spatial data to generate map data. In other words, this is for providing the user's time information and location information on the map data and specifying the location on the map data corresponding to the location information.

Management server 130 may store all internally processed information in database 140 .

A database (DB) 140 can classify and store information on the user terminal 110, user IDs, user information, time information, location information, map information, and user blocks for each user ID.

At this time, the database 140 may be located inside or outside the management server 130 . If it is located outside, it can be set to store data and information when it is received in conjunction with the management server 130 .

Metaverse server 150 can provide a virtual Metaverse space, and can provide various virtual reality content within the Metaverse space. This allows the user to connect to the Metaverse server 150 using his/her own user terminal 110 and use the Metaverse space and the content provided in the Metaverse space. At this time, advertisements in the Metaverse space can be provided in the form of particles.

User information is required when a user uses the Metaverse server 150, but the user information can be changed by checking the user block, so there is no need to separately manage the user information. At this time, when the user enters the Metaverse space through the user terminal 110, the Metaverse server 150 can check the blockchain to check the user information of the user.

User's avatar information and content usage information can also be stored in the user block, and the user block is distributed and stored in the user terminal 110, the management server 130, and the metaverse server 150, and cannot be forged or altered.

In this embodiment, the Metaverse server 150 can provide advertisements to specific areas in the Metaverse space when the user uses the Metaverse space through the user terminal 110 .

Such advertisements are user-customized advertisements and can be advertisements corresponding to user's interests. User-customized advertisements are described in detail below.

When the Metaverse space and the virtual reality content are executed, the Metaverse server 150 confirms that the user has logged in or entered the Metaverse space, requests an advertisement from the advertisement server 160, and displays the advertisement at a specific position in the Metaverse space. can be displayed.

The Metaverse server 150 can check the number of times the advertisement is clicked by the user terminal 110 and upgrade the level of the user's avatar. For example, it is possible to upgrade the clothes, shoes, etc. of the team leader avatar who participated in the virtual conference room as the team leader, or upgrade accessories such as glasses and watches.

At this time, the number of clicks on the advertisement can be stored in the user block, agreed within the public consensus network 10, and distributed and stored after being authenticated by the management server 130. FIG.

By clicking on the advertisement, the user can not only transform into an avatar through the user terminal 110, but also receive a discount coupon for the product advertised through mileage accrual. . At this time, since the number of clicks cannot be forged or altered, the reliability of the number of clicks can be improved.

The advertisement server 160 may receive an advertisement request from an advertiser terminal 180 of an advertiser and transmit the request to the Metaverse server 150 . At this time, the advertisement server 160 can transmit user-customized advertisements.

User-customized advertisements are described in detail below.

The management server 130 may analyze the time information and location information of the movement pattern of the user terminal 110 to understand the user's interest field. User interests can be recorded in user blocks.

When the Metaverse server 150 confirms that the user has entered the Metaverse space through the user terminal 110, the Metaverse server 150 can transmit a user-customized advertisement request to the advertisement server 160 together with the user ID.

Therefore, the advertisement server 160 searches the public consensus network 10 for an interest field corresponding to the user ID transmitted from the metaverse server 150, and selects the interest field of the user ID from a large number of pre-stored advertisements. customized advertisements can be extracted and transmitted to the metaverse server 150 .

Then, the Metaverse server 150 can display the interest field advertisement in a specific area in the Metaverse space used by the user. Accordingly, the user can view and check customized advertisements corresponding to his/her field of interest in the Metaverse space through the user terminal 110 .

The user can click on the advertisement on user terminal 110 . The Metaverse server 150 can check the number of ad clicks and store it in the user's block. Such user blocks can be agreed within the public consensus network 10 and distributed and stored after being authenticated by the management server 130 .

Advertisement server 160 may receive advertisement requests from advertiser terminal 180 and store them in an internal storage location (not shown) or in a separate database (not shown). At this time, the requested advertisements can be classified according to categories and stored. Such categories can correspond to areas of interest.

The ad server 160 can coordinate the public consensus network 10 and the private consensus network 20 . This is to combine an open network targeting a large number of user terminals 110 and a closed network targeting a relatively small number of advertiser terminals 180 into one, and blocks of different methods are used. Chain technology can be applied.

The user terminal 110 includes a corresponding user block, which may include the user's interests so that the advertisement server 160 can provide user-customized advertisements. This block can be confirmed by the ad server 160 with user consent within the public consensus network 10 .

In another embodiment of the present invention, the management server 130 analyzes the interest areas based on the time information and location information of the user terminal 110, and may give different weights to the interest areas according to the time information. In other words, a higher weight can be assigned to a longer time spent at a particular position. In particular, when a user has a plurality of interest fields, different weights can be assigned to each interest field according to time information.

For example, as a result of analyzing the movement pattern of the user terminal 110 in one month, the user terminal 110 spent 15 hours on the soccer field, 10 hours on the mountain, and 5 hours on the swimming pool. In this case, the areas of interest can be analyzed as soccer, mountaineering, and swimming, and since the time corresponding to each area of interest is different, the highest weight is given to soccer, which spends the most time, the middle weight is given to mountaineering, and swimming is given. can be given low weight.

Such weights can be related to advertising time. Weight information for each user's interest field can be recorded in the user block. Alternatively, the management server 130 may transmit weight information for each field of interest to the Metaverse server 150 together with the user's ID.

Therefore, when the Metaverse server 150 displays the advertisement corresponding to the user's ID in the Metaverse space, the soccer-related advertisement having a high weight can be displayed for a relatively long time and the swimming advertisement can be displayed for a relatively short time.

In this way, the advertisement exposure time can be set differently for each user according to the degree of interest. Accordingly, by displaying an advertisement with a high degree of interest for a relatively long time, it is possible to enhance the effectiveness of the advertisement.

Also, as described above, when the interest field is graded, the advertisement time can be set according to the grade. For example, high-grade interest area advertisements can be longer.

Higher-ranked interest areas may also be given higher weights for longer advertising times.

The advertisement server 160 can recruit multiple advertisers through contracts and form a private consensus network 20 with the advertiser terminals 180 of the advertisers. Ad server 160 can be a common node in public consensus network 10 and private consensus network 20 .

The public consensus network 10 is an open network in which any member of the metaverse server 150 participates, and the private consensus network 20 is a closed network in which only the advertiser terminal 180 permitted by the advertisement server 160 participates. It can be understood.

The contract between the advertiser terminal 180 and the advertisement server 160 can be the number of advertisement exposures, i.e., the number of advertisement confirmations, and the information on the number of clicks so that the actual number of advertisement exposures cannot be forged or altered. It can be distributed and stored in the private consensus network 20 .

FIG. 3 is a flow chart illustrating a method for providing user-customized advertisements in the Metaverse space using blockchain according to an embodiment of the present invention.

Referring to FIG. 3, the user terminal 110, the metaverse server 150, and the advertisement server 160 are authorized to use the public consensus network 10 through the authentication of the management server 130, and can generate a user block for the user terminal 110. (S101).

The user terminal 110 can measure its own position using an internal GPS module (not shown) and record user information including its own ID along with location information and time information accordingly in the user block. Yes (S103).

When a user logs into the management server 130 and the Metaverse server 150 through the user terminal 110 , the user information stored in the user block corresponding to the user terminal 110 can be used to log in.

The management server 130 may analyze the user's interest field based on the time information and location information of the user terminal 110 (S105). Specifically, when the user terminal 110 remains at a specific position for a set time or longer, the field corresponding to the specific position can be set as the field of interest.

For example, soccer can be set as a field of interest if the user stays at a soccer field for a certain amount of time or more during a month. Such areas of interest can be agreed upon in the public consensus network 10 and recorded in user blocks.

In another embodiment, the management server 130 may set the field corresponding to the specific position as the field of interest when the number of visits to the specific position during the set time is equal to or greater than a reference value. can. This is because the higher the interest, the more people visit during the set period.

The information that the user terminal 110 has logged into the management server 130 and/or the metaverse server 150 is transmitted to the advertisement server 160, and the advertisement server 160 confirms the user block corresponding to the logged-in user terminal 110, and if there is an agreement. For example, a customized advertisement corresponding to the field of interest of the user is transmitted to the Metaverse server 150 (S107).

In another embodiment, in step S107, the Metaverse server 150 checks the login information of the user terminal 110, requests the advertisement server 160 for user-customized advertisements corresponding to the user's field of interest, and the advertisement server 160 accesses the Metaverse. User customized advertisements can also be transmitted to server 150 .

The fact that the user terminal 110 is logged into the Metaverse server 150 may mean that the user has entered the Metaverse space provided by the Metaverse server 150 through the user terminal 110 .

The Metaverse server 150 may display the received customized advertisement in a region set within the Metaverse space (S109). Thereby, the user can use the user terminal 110 to view the advertisement displayed in the Metaverse space while using the Metaverse space (S111). Such viewing can also be viewed by clicking on an advertisement.

Information on the number of clicks on the advertisement is recorded in the user block and can be distributed and stored after agreement within the public consensus network 10 .

Here, a process of distributing user information, login information, advertisement click count, etc. of the user terminal 110 to the public consensus network 10 will be described.

The management server 130 provides the certificate in response to the request of the user terminal 110 . The certificate includes a transaction certificate, which is a one-time-only certificate used each time a transaction is generated to protect the privacy of the user terminal 110, and a registration certificate that certifies the identity of the user terminal 110. can be done.

The registration certificate can be issued by the user terminal 110 joining the metaverse server 150 as a member and providing the result to the management server 130, and can be used without renewal while the membership is maintained. can be set to

The transaction certificate can be issued by the management server 130 at the request of the user terminal 110 when processing items such as change of user information, login information to the Metaverse server 150, change of the number of advertisement clicks, etc. occur.

The transaction certificate issued in this way is stored in the electronic wallet of the user terminal 110, and is used to access the ledger of the public consensus network 10, which is a consensus network. The management server 130 verifies each ledger change and distributes and stores the results in a separate state.
