In addition, when the illuminance of the second display unit 120 falls within the second range, the processor 130 may recognize that at least one advertisement being displayed on the second display unit 120 is being exposed.

On the other hand, the processor 130 of the first user terminal 100a when the slope does not belong to the first range while one advertisement is being displayed on the second display unit 120 (S220, No), at least one advertisement can be recognized as not being exposed.

For example, when the inclination of the second display unit 120 with the ground is 0°, the processor 130 may recognize that the inclination does not belong to the first range. Accordingly, the processor 130 may recognize that at least one advertisement being displayed on the second display unit 120 is not being exposed. However, the present invention is not limited thereto.

On the other hand, when the illuminance of the light input to the second display unit 120 does not belong to the second range (S340, No), the processor 130 of the first user terminal 100a is not exposed to at least one advertisement. can be recognized as not

It is possible to recognize whether at least one advertisement being displayed is being exposed to the outside. Through this, the processor 100a may recognize a case where the inclination of the second display unit 120 with the ground is sufficient to expose at least one advertisement to the outside, but is obscured by a wall or a user's hand. Accordingly, when the advertisement being displayed in the first user terminal 100a is not exposed to the outside, the generation of revenue can be further prevented.

Meanwhile, according to some embodiments of the present disclosure, when at least one advertisement is exposed to the outside, it may be reduced or a displayed area may be changed so as not to be covered by a user's hand. Hereinafter, a method for the processor to determine an area in which at least one advertisement is displayed will be described with reference to FIG. 7 .

7 is a diagram for describing an example of a method for a processor to determine an area in which at least one advertisement is displayed, according to some embodiments of the present disclosure.

Referring to FIG. 7A , the processor 130 of the first user terminal 100a may display at least one advertisement on the second display unit 120 .

Also, when at least one advertisement is being displayed on the second display unit 120 , the processor 130 may recognize the first area R1 in which the at least one advertisement is displayed.

For example, when at least one advertisement is being displayed on the entire screen of the second display unit 120 , the processor 130 may recognize the entire screen of the second display unit 120 as the first region R1 . can

Meanwhile, at least one advertisement being displayed on the second display unit 120 may be partially covered by the user's hand or the like.

Specifically, referring to FIG. 7B , the user may hold the first user terminal 100a as shown in the drawing when using the first user terminal 100a.

In this case, the processor 130 of the first user terminal 100a may recognize whether a touch input is detected in the first area R1 of the second display unit 120 .

On the other hand, when the processor 130 of the first user terminal 100a recognizes that a touch input is detected in the first area R1, the processor 130 of the second display unit 120 having a smaller size than the first area R1 is displayed. At least one advertisement may be displayed in the second area R2. Here, the second region R2 may be a region in which a touch input is not sensed.

Specifically, the processor 130 may recognize the third region R3 in which the touch input is sensed within the first region R1 . Also, when the third region R3 is recognized, the processor 130 may determine the second region R2 using the first region R1 and the third region R3 .

For example, the second region R2 may be a region in the first region R1 excluding the third region R3 . However, the present invention is not limited thereto. In addition, the processor 130 may display at least one advertisement in the determined second area R2 .

Meanwhile, according to some embodiments of the present disclosure, the processor 130 of the first user terminal 100a may change the size of at least one advertisement.

Specifically, when the processor 130 determines the second area R2 by detecting a touch input in the first area R1 of the second display unit 120 in which at least one advertisement is displayed, the second area ( The size of at least one advertisement may be changed based on the size of R2).

For example, the processor 130 may reduce the size of the at least one advertisement so that the at least one advertisement can be displayed in the second area R2 . However, the present invention is not limited thereto.

Meanwhile, according to some embodiments of the present disclosure, the processor 130 of the first user terminal 100a may change at least one advertisement being displayed on the second display unit 120 .

Specifically, when the processor 130 determines the second area R2 by detecting a touch input in the first area R1 of the second display unit 120 in which at least one advertisement is displayed, the second area ( At least one advertisement smaller than the size of R2) may be recognized. In addition, the processor 130 may display at least one advertisement smaller than the recognized size of the second area R2 in the second area R2 . However, the present invention is not limited thereto.

Meanwhile, according to some embodiments of the present disclosure, the processor 130 of the first user terminal 100a may enlarge the size of an area in which at least one advertisement is displayed.

Specifically, the processor 130 may recognize whether the touch input has been removed from the third region R3 of the second display unit 120 where at least one advertisement is displayed.

On the other hand, when the touch input is removed by the user releasing his/her hand from the third region R3 , the processor 130 displays at least one advertisement in the first region R1 of the second display unit 120 . may control the second display unit 120 to be displayed again.

For example, the processor 130 displays at least one advertisement in the entire area of the second display unit 120 when the touch input is removed by the user releasing the hand from the third area R3. The second display unit 120 may be controlled so as to be possible.

In this case, the processor 130 may also enlarge the size of at least one advertisement being displayed in the second area R2 . That is, the processor 130 may enlarge the size of at least one advertisement being displayed in the second area R2 as shown in FIG. 7(b) to be displayed in the first area R1 as shown in FIG. 7(a). . However, the present invention is not limited thereto.

Meanwhile, according to some embodiments of the present disclosure, the size of at least one advertisement may be changed according to a user input.

Specifically, when at least one content is displayed on the first display unit 110 , the processor 130 of the first user terminal 100a selects or selects at least one advertisement to be displayed on the second display unit 120 . An editing command may be received from the user. Here, the command may be received through a pop-up window through which a user can input. However, the present invention is not limited thereto. Upon receiving the command, the processor 130 of the first user terminal 100a may select or edit at least one advertisement displayed on the second display unit 120 based on the command.

For example, the processor 130 may receive an input for reducing the size of at least one advertisement displayed on the second display unit 120 from the user of the first user terminal 100a. As another example, the processor 130 may receive an input for displaying a specific advertisement among at least one advertisement displayed on the second display unit 120 from the user of the first user terminal 100a. In addition, the processor 130 may display at least one advertisement based on the user's input. However, the present invention is not limited thereto.

As described above, when at least one advertisement being exposed on the second display unit 120 is partially covered by the user (ie, at least a portion is not exposed), the processor 130 of the first user terminal 100a If not), at least one advertisement may be moved to a position not covered by the user. Accordingly, even if the user uses the first user terminal 100a while the advertisement is displayed on the second display unit 120 , the user can expect a profit through the advertisement exposure.

8 is a flowchart illustrating an example of a method in which a server generates a reward for a first user terminal based on time information related to the first user terminal according to some embodiments of the present disclosure.

Referring to FIG. 8 , the processor 210 of the server 200 provides time information on the time when the first user terminal 100a exposed at least one advertisement from at least one node included in the block chain network 300 . Alternatively, the first transaction including time information may be inquired (S410).

Specifically, the processor 210 transmits to the block chain network 300 a query that can be used to inquire time information related to the first user terminal 100a or a first transaction containing time information to the block chain network 300 ( 220) can be controlled. Then, the block chain network 300 receiving the query may cause the processor 210 to inquire the time information or the first transaction related to the first user terminal 100a.

Meanwhile, the processor 210 may inquire the time information or the first transaction related to the first user terminal 100a at a preset time interval. Here, the preset time may be pre-stored in the storage unit 230 . However, the present invention is not limited thereto, and the processor 210 may aperiodically inquire the time information or the first transaction.

When the time information or the first transaction is inquired, the processor 210 of the server 200 may determine a reward related to the first user terminal 100a based on the time information (S420).

Here, the reward may include quantitative information on the amount of coins generated as the first user terminal 100a exposes at least one advertisement.

A coin may mean any type of cryptocurrency that can be operated on the blockchain network 300 .

Specifically, at least one content executable in the first user terminal 100a may be stipulated to pay a cost necessary for execution when purchasing an item, downloading content, or playing a video. At this time, the coin may be any form of medium that can be transacted within the blockchain network 300 to be paid as an execution cost. However, the present invention is not limited thereto.

Meanwhile, when the reward is determined, the processor 210 of the server 200 may generate a transfer transaction for transferring the amount of coins corresponding to the reward to the account related to the first user terminal 100a ( S340 ).

Here, the account related to the first user terminal 100a may mean a wallet address related to the first user terminal 100a managed by the block chain network 300 . For example, the block chain network 300 may store quantitative information about the amount of coins stored in the wallet of the first user terminal 100a.

In this case, the server 200 may generate a transfer transaction capable of modifying, changing, and updating information on the amount of coins currently stored in the wallet of the first user terminal 100a. However, the present invention is not limited thereto.

On the other hand, the processor 210 of the server 200 controls the communication unit 220 to transmit the transfer transaction to at least one node included in the block chain network 300, so that a plurality of nodes performs the transfer transaction through a consensus algorithm. It may cause to write to a block (S440).

Specifically, when a transfer transaction is received from the server 200 to at least one node in the blockchain network 300 , a plurality of nodes may verify the transfer transaction through a consensus algorithm. In addition, each of the plurality of nodes may generate a block to record a transfer transaction in the generated block.

On the other hand, when a transfer transaction is recorded in the blockchain network 300, it is virtually impossible for the transfer transaction to be forged or tampered with. Accordingly, the transfer transaction paid as the first user terminal 100a exposes an advertisement may be prevented from being modified by a third party, and the transfer transaction may be guaranteed in a state in which integrity can be guaranteed.

According to the above configuration, the server 200 may determine a reward based on the reliable time information generated by the first user terminal 100a. In addition, since the server 200 also causes the generated reward to be recorded in the blockchain network 300 , the user of the first user terminal 100a can be transparently compensated for the revenue according to the exposure of at least one advertisement.

Meanwhile, according to some embodiments of the present disclosure, the reward may be determined based on at least one action occurring in the external terminal. Hereinafter, a method in which the server 200 determines a reward based on at least one action will be described with reference to FIG. 9 .

At least one related advertisement may be displayed. In addition, the processor 210 of the server 200 may determine a reward based on the time when at least one advertisement is exposed on the second display unit 120 of the first user terminal 100a. In this case, the processor 210 of the server 200 may recognize whether at least one action has occurred from the external terminal, and determine a reward based on the number of times the at least one action has occurred.

Referring to FIG. 9 , when the at least one second user terminal 100b performs the first action (S510, Yes), the processor 210 of the server 200 performs the at least one second user terminal 100b. A first time point at which this first action is performed may be recognized (S520). Here, the first action is at least one of accessing a homepage related to at least one advertisement being exposed in the first user terminal 100a, downloading at least one content related to at least one advertisement, or installing an application related to at least one advertisement. may contain one.

Specifically, the processor 210 may recognize whether the at least one second user terminal 100b has performed the first action. In this case, the processor 210 may recognize a first time point at which the at least one second user terminal 100b performs the first action.

As an example, the processor 210 may use log data in which information indicating that the second user terminal 100b has accessed a homepage related to at least one advertisement being exposed in the first user terminal 100a is recorded, such as through log data, etc. 2 It may be recognized that the user terminal 100b has performed the first action. In addition, the processor 210 may recognize a first time point, which is a time point of visiting the homepage of the second user terminal 100b.

As another example, the processor 210 records information that the second user terminal 100b has downloaded at least one content related to at least one advertisement being exposed in the first user terminal 100a, log data, etc. Through this, it can be recognized that the second user terminal 100b has performed the first action. In addition, the processor 210 may recognize a first time point that is a download time point of at least one content of the second user terminal 100b.

As another example, the processor 210 may record information indicating that the second user terminal 100b has installed at least one advertisement-related application being exposed in the first user terminal 100a through log data, etc. , at least one second user terminal 100b may be recognized. In addition, the processor 210 may recognize the first time point at which the second user terminal 100b installed the application. However, the present invention is not limited thereto.

Meanwhile, the processor 210 of the server 200 determines the first position of the first user terminal 100a at the first time point when the first time point is included within the time when at least one advertisement is exposed (S530, Yes). and a second location of the at least one second user terminal 100b (S540).

Specifically, the processor 210 may recognize a first time point at which the at least one second user terminal 100b performs the first action. Then, the processor 210 determines that the first user terminal 100a in which the first time point is recorded in the time information based on the time information recorded in the block chain network 300 or the first transaction including the time information is at least one It is possible to recognize whether the advertisement is included in the exposure time. When the processor 210 recognizes that the first time point is included in the time at which the at least one advertisement included in the time information is exposed, the first location of the first user terminal 100a at the first time point and the at least one second 2 The second location of the user terminal 100b may be recognized. Here, the first location of the first user terminal 100a may be recognized through a GPS sensor provided in the first user terminal 100a. Also, the second location of the at least one second user terminal 100b may be recognized through a GPS sensor provided in the at least one second user terminal 100b. However, the present invention is not limited thereto.

Meanwhile, the processor 210 of the server 200 may recognize the number of times the first action has occurred when the distance between the first location and the second location at the first time point is less than or equal to a preset distance (S550, Yes) ( S560). Here, the preset distance is a distance that can be recognized that the user of the second user terminal 100b is in the same location as the user of the first user terminal 100a, and is pre-stored in the storage unit 230 of the server 200. can However, the present invention is not limited thereto.

Specifically, when the distance between the first location and the second location is less than or equal to a preset distance at the first time point, the processor 210 may recognize that the distance between the first location and the second location is less than or equal to the preset distance. In addition, the processor 210 may recognize the number of times the first action has occurred in the at least one second user terminal 100a. For example, the processor 210 may recognize that at least one second user terminal 100a has accessed a homepage related to at least one advertisement being exposed in the first user terminal 100a once. Also, the processor 210 may recognize that the at least one second user terminal 100a has downloaded at least one content related to at least one advertisement being exposed in the first user terminal 100a once. In this case, the processor 210 may recognize that the number of times the first action has occurred is twice. However, the present invention is not limited thereto.

Meanwhile, when the first action occurs, the processor 210 of the server 200 may determine a reward based on time information and the number of times the first action occurs ( S570 ).

Specifically, the processor 210 may determine the reward by using the time the at least one advertisement was exposed in the first user terminal 100a and the number of times the first action occurred during the time at which the at least one advertisement was exposed. Here, when the reward is determined by using the number of times the first action is generated together with the time when the at least one advertisement is exposed, the reward may be determined to be larger than when the reward is determined using only the time when the advertisement is exposed.

More specifically, the processor 210 of the server 200 may recognize the first weight value set in the first action when determining the reward using the number of times the first action is generated. Here, the first weight value may be a weight that may be weighted in determining a reward. In addition, the processor 210 may determine the first sub-reward based on time information about the time the advertisement was exposed in the first user terminal 100a. Also, the processor 210 may determine the second sub-reward by multiplying the number of times the first action has occurred and a first weight value set for the first action. Then, the processor 210 may determine a reward by adding the first sub-reward and the second sub-reward. However, the present invention is not limited thereto.

According to the above-described configuration, the user of the first user terminal 100a can expect more revenue through the first action generated according to the exposure of at least one advertisement displayed on the second display unit 120 . Accordingly, the user may act so that the at least one advertisement may be more exposed, and this may also make the advertiser or publisher related to the at least one advertisement generate greater revenue.

Meanwhile, the reward may be determined based on a second action that may be generated from the at least one third user terminal 100b. Hereinafter, a method of determining a reward based on the number of times the second action occurs will be described with reference to FIG. 10 .

10 is a flowchart illustrating an example of a method in which a server determines a reward based on time information, the number of times a first action occurs, and a number of times a second action occurs, according to some embodiments of the present disclosure.

Referring to FIG. 10 , when the at least one third user terminal 100c performs the second action (S610, Yes), the processor 210 of the server 200 performs the at least one third user terminal 100c. It is possible to recognize the number of times the second action has occurred (S620). Here, the second action includes accessing the homepage through the first address generated by the first user terminal 100a, downloading at least one content through the first address, and installing at least one application through the first address. may include at least one of Also, the first address may include identification information of the first user terminal 100a.

Specifically, when the processor 130 of the first user terminal 100a displays at least one advertisement on the second display unit 120 , the first information may be broadcast to an unspecified number of user terminals. Here, the first information includes a first address for accessing a homepage related to at least one advertisement including identification information of the first user terminal 100a and at least one information including identification information of the first user terminal 100a. It may include at least one of the first address for downloading at least one application related to the advertisement. However, the present invention is not limited thereto.

When the first user terminal 100a broadcasts the first signal, at least one third user terminal 100c receives the first signal and receives the second signal through the first address included in the received first signal. action can be performed.

For example, the at least one third user terminal 100c may perform a second action of accessing a homepage related to at least one advertisement being exposed in the first user terminal 100a through the first address. Alternatively, the at least one third user terminal 100c downloads at least one application related to at least one advertisement being exposed in the first user terminal 100a through the first address included in the first information. can also be performed. In addition, the processor 210 of the server 200 may recognize the number of times the second action is generated in the at least one third user terminal 100c.

For example, in the processor 210, the at least one third user terminal 100a accesses the homepage once through the first address, and the at least one third user terminal 100a connects to the at least one website through the first address. It can be recognized that the content has been downloaded once. In this case, the processor 210 may recognize that the second action occurs twice. However, the present invention is not limited thereto.

On the other hand, when the processor 210 of the server 200 recognizes the number of times the second action occurs, the reward may be determined based on time information, the number of times the first action occurs, and the number of times the second action occurs (S630). ).

Specifically, the processor 210 determines the time at which the at least one advertisement was exposed in the first user terminal 100a, the number of times the first action occurred during the time at which the at least one advertisement was exposed, and the time at which the at least one advertisement was exposed. The reward may be determined using the number of times the second action is generated during the period. Here, when determining the reward using the number of times the second action occurs together with the time at least one advertisement is exposed, it is a reward rather than determining the reward using the time at which the advertisement was exposed and the number of times the first action occurred. can be largely determined.

More specifically, the processor 210 of the server 200 may recognize the second weight value set in the second action when determining the reward using the number of times the second action is generated. Here, the second weight value may be a weight that may be weighted in determining a reward. Also, the second weight value may be greater than the first weight value. In addition, the processor 210 may determine the first sub-reward based on time information about the time the advertisement was exposed in the first user terminal 100a. Also, the processor 210 may determine the second sub-reward by multiplying the number of times the first action has occurred and a first weight value set for the first action. Also, the processor 210 may determine the second sub-reward by multiplying the number of times the second action has occurred and a second weight value set in the second action. In addition, the processor 210 may determine a reward by summing the first sub-reward, the second sub-reward, and the third sub-reward. However, the present invention is not limited thereto.

According to the above configuration, the user of the first user terminal 100a can expect more revenue through the second action generated according to the exposure of at least one advertisement displayed on the second display unit 120 . Accordingly, the user may broadcast at least one advertisement more frequently in anticipation of greater revenue. This may also make it possible to generate greater revenue for advertisers or publishers related to at least one advertisement.

Specifically, when receiving an input from the user of the first user terminal 100a to execute at least one content, the processor 130 may display the at least one content on the first display unit 110 .

For example, when receiving an input to execute a game from the user, the processor 130 may display an execution screen of at least one game on the first display unit 110 after executing the game.

When at least one content is displayed on the first display unit 110 , the user terminal 100 may determine whether to display at least one advertisement related to the at least one content on the second display unit 120 ( S720).

Specifically, when an input to display at least one advertisement is received from the user of the first user terminal 100a , the processor 130 may display the at least one advertisement on the second display unit 120 .

For example, when receiving an input to display an advertisement from the user, the processor 130 may control the second display unit 120 to display at least one advertisement on the second display unit 120 .

Meanwhile, the user terminal 100 may recognize whether at least one advertisement is being displayed while at least one advertisement is being displayed on the second display unit 120 ( S730 ).

Specifically, the processor 130 may recognize the tilt and illuminance of the second display unit 120 through the sensor unit 140 while at least one advertisement is being displayed on the second display unit 120 . In addition, the user terminal 100 may recognize whether at least one advertisement is being exposed based on the measured inclination or illuminance.

For example, in the user terminal 100 , the inclination of the second display unit 120 measured through the acceleration sensor of the sensor unit 140 falls within the first range, and the inclination of the second display unit 120 measured through the second illuminance sensor 142 is When the illuminance falls within the second range, it may be recognized that at least one advertisement is being exposed. However, the present invention is not limited thereto.

Meanwhile, when the user terminal 100 recognizes that at least one advertisement is being exposed, the user terminal 100 may generate time information about the time at which the at least one advertisement was exposed ( S740 ).

For example, the user terminal 100 may generate time information based on a time from when it is recognized that at least one advertisement is being exposed to a time when at least one advertisement is not exposed. However, the present invention is not limited thereto.
