3 is a conceptual diagram illustrating a signal flow between respective components in an advertisement providing system.

Referring to FIG. 3 , the advertisement providing system may include a client 310, a CDN 320, a proxy 330, a web server 340, and an advertisement server 350. However, some components of the advertisement providing system may be omitted.

Referring to FIG. 3 , in ①, the client 310 may request HTTP content from the web server 340 . A request for HTTP content can be made by invoking a specific link or starting an arbitrary application that loads the content. The HTTP content request may be sent in the form of an HTTP GET request, typically along with an address such as web server 340 and a URL identifying the content. HTTP content requests may be forwarded to web server 340 via CDN 320 and/or proxy 330 .

In ②, the web server 340 may transmit an HTTP response corresponding to the HTTP content request to the proxy 330. Here, the HTTP response may include HTTP content and advertising information for calling an advertisement. The advertisement information may include an address of the advertisement server 350 and an HTML attribute for designating an advertisement.

The proxy 330 may modify at least a part of the HTTP response received from the web server 340 . For example, the proxy 330 may modify content, advertisement information, and the like included in the HTTP response. According to an embodiment, the proxy 330 may perform operations such as encrypting and/or obfuscating content and/or advertisement information. Specifically, the proxy 330 may obfuscate at least a portion of the HTTP response by generating a plurality of layer tags and attribute values of each of the tags and adding them to a region including advertisement information in the HTTP response.

Alternatively, the proxy 330 may add a command such as a script to the HTTP response. And in ③, the proxy 330 may transmit the modified HTTP response to the client 310. The modified HTTP response may be forwarded to the client 310 through the CDN 320, but may also be transmitted directly without going through the CDN 320.

The client 310 requesting the HTTP content may receive an HTTP response including the HTTP content from the proxy 330 and/or the CDN 320 . An advertisement blocking function executed by the client 310 may block an advertisement call based on advertisement information included in an HTTP response. According to one embodiment, the ad blocker may block rendering of an advertisement area and/or advertisement information using a CSS rule.

However, since the area including advertisement information in the modified HTTP response is obfuscated, the advertisement blocker may not be able to specify the area including advertisement information in the HTTP response. Therefore, ad blockers may not be able to block ad areas using algorithms such as CSS rules. That is, at least some of the obfuscated areas of the HTTP response can avoid ad blockers.

In ④, if the advertisement information included in the HTTP response is not blocked despite the advertisement blocking function by the client 310, the client 310 sends the advertisement server 350 based on the advertisement information included in the HTTP response. Ads may be requested.

In ⑤, the client 310 may receive an advertisement response from the advertisement server 350 and output an advertisement based on the received advertisement response. Thus, the client 310 can successfully invoke advertisements.

Operations of devices due to the flow of signals exchanged between devices of the advertisement providing system may be as described below.

4 is a flowchart illustrating the operation of each component in the advertisement providing system.

Referring to FIG. 4 , the advertisement providing system may include a client, a CDN, a proxy, a web server, and an advertisement server. However, some components of the advertisement providing system may be omitted.

In step S401, the client may transmit an HTTP request to the web server. Here, the HTTP request may be forwarded to the web server via a CDN and/or proxy.

In step S403, the web server may transmit an HTTP response corresponding to the HTTP request to the proxy.

In step S405, the proxy may obfuscate at least a portion of the HTTP response. Here, at least some areas of the HTTP response may be areas including advertisement information. In addition, at least some of the obfuscated regions may further include tags and attribute values irrelevant to calling of advertisement information.

In step S407, the proxy may modify the HTTP response. For example, the proxy may modify the HTTP response by obfuscating at least a portion of the HTTP response. Alternatively, the proxy may add a recovery script to the HTTP response.

In step S409, the proxy may transmit the modified HTTP response to the client. Here, the modified HTTP response may be forwarded to the client through the CDN.

In step S411, the client may execute an advertisement blocking function. Due to the obfuscated area of at least a part of the HTTP response, the ad blocker may not be able to specify the area including advertisement information in the HTTP response. As a result, at least some areas of the obfuscated HTTP response can avoid ad blockers.

When the advertisement information included in the HTTP response is not blocked by the client's advertisement blocking function, in step S413, the client may request the advertisement information included in the HTTP response.

In step S415, the client may receive a response to the advertisement information request from the advertisement server. Accordingly, the client may render advertisement information acquired from the advertisement server.

A specific operation of the proxy of the advertisement providing system may be as follows.

5 is a flowchart illustrating the operation of the proxy of the advertisement providing system.

In step S601, the proxy may receive an HTTP request from the client.

In step S603, the proxy may request content corresponding to the HTTP request from the external server and obtain an HTTP response corresponding to the HTTP request from the external server. Here, the HTTP response may include information about the first advertisement. Information about the first advertisement may include information and/or script for invoking the first advertisement. For example, the information for calling the first advertisement may be an address such as a URL or URI for requesting an advertisement from an advertisement server.

In step S605, the proxy may modify the HTTP response received from the external server. Specifically, the proxy may insert at least one script and/or command into the HTTP response to circumvent the client's ad blocker. The proxy's operation of modifying the HTTP response may be as described below.

6 is a flowchart illustrating an operation of modifying an HTTP response of a proxy of an advertisement providing system.

In step S701, the proxy may generate a plurality of layer tags and an attribute value of each of the tags. Here, the plurality of layer tags and attribute values may be layer tags and attribute values unrelated to the output operation of the HTTP response. In addition, a plurality of layer tags and attribute values may be arbitrarily generated for each HTTP request. A layer tag irrelevant to the output of an HTTP response including advertisement information may be referred to as a dummy tag.

In step S703, the proxy may obfuscate at least a part of the HTTP response by adding the generated dummy tag to the HTTP response. Here, at least a partial area may be an area including a script related to the first advertisement information included in the HTTP response received from the external server. Also, at least some area may include at least one command and/or script for calling a second advertisement from its own advertisement server.

That is, the proxy may obfuscate a region including a script for the first advertisement information and/or a command for calling the second advertisement by adding a dummy tag to the HTTP response. Here, the dummy tag may be information unrelated to an operation for outputting the first advertisement information executed by the client. Here, at least a part of the area may be referred to as an advertisement call area including a dummy tag and information about the first advertisement and/or the second advertisement.

In step S705, the proxy may generate a recovery script for utilizing at least some areas of the HTTP response. The recovery script may include at least one command for utilizing at least a partial area of the HTTP response. Here, at least a partial area may be an area including a script related to the first advertisement information included in the HTTP response received from the external server. At least one command of the repair script may be executed by the client.

The recovery script may include commands executed by the client to determine whether an ad blocking function is executed. In addition, the recovery script may include commands executed to encrypt information for requesting a separate advertisement and transmit encrypted advertisement request information when the call of the first advertisement included in the HTTP response is blocked by the client. . In order to determine whether the advertisement blocking function is executed, a method of adding an area including advertisement information that can be commonly blocked in the modified HTTP response can be used. It is sufficient to determine whether the ad blocking function is executed or not by giving a clue that the ad blocking function can be blocked by the known functions of the ad blocker.

In step S707, the proxy may add a recovery script to the HTTP response. Accordingly, the HTTP response modified by the proxy may include dummy tags for obfuscating at least a portion of the area including the script for the first advertisement information and a recovery script for utilizing the at least partial area. However, it is obvious that the modified HTTP response may not include a dummy tag and/or a recovery script, and may further include an additional configuration for securing utilization of at least some areas.

Referring back to FIG. 5 , in step S607, the proxy may transmit a modified HTTP response. According to an embodiment, the modified HTTP response may include a region related to the obfuscated first advertisement information. According to another embodiment, the modified HTTP response may include a recovery script for utilizing at least a part of the area, such as the area related to the first advertisement information.

The client may receive a modified HTTP response from the proxy. The operation of the client receiving the modified HTTP response may be as described below.

7 is a flowchart illustrating an operation of a client of an advertisement providing system that has received a modified HTTP response.

In step S801, the client may receive a modified HTTP response from the proxy.

Upon receiving the modified HTTP response, the client's ad blocker may execute an ad blocking function. However, due to the obfuscated area of the modified HTTP response, the ad blocker of the client may not be able to specify the advertisement area in the HTTP response. Thus, ad blockers may not be able to block ads in HTTP responses.

In step S803, the client may determine whether to block the first advertisement information included in the modified HTTP response due to the execution of the advertisement blocking function.

If the first advertisement information included in the modified HTTP response is not blocked, in step S805-1, the client may transmit a first advertisement request to the advertisement server based on the first advertisement request information.

On the other hand, if the first advertisement information included in the modified HTTP response is blocked, in step S805-2, the client may execute at least one command of the recovery script. That is, the client may execute at least one command of the repair script in order to replace the first advertisement information included in the modified HTTP response and utilize a partial area of the HTTP response related to the advertisement information.

In step S807, the client may receive advertisement information corresponding to the advertisement request from the advertisement server. When the client does not block the first advertisement information included in the modified HTTP response, the client may receive the first advertisement from the advertisement server. When the client blocks the first advertisement information included in the modified HTTP response, the client may receive a second advertisement provided by its own advertisement server from the proxy.

Here, the second advertisement received from the proxy may be encrypted information. The client receiving the encrypted second advertisement may decrypt the second advertisement by executing at least one command of the recovery script.

In step S809, the client can output the received advertisement. Accordingly, the client may output the first advertisement or the second advertisement regardless of whether the advertisement blocking function is executed or not.

Here, a signal flow between a client executing at least one command of the recovery script in the advertisement providing system and components of the advertisement providing system may be as follows.

8 is a conceptual diagram illustrating a signal flow between components in an advertisement providing system.

Referring to FIG. 8 , the advertisement providing system may include a client 310, a CDN 320, a proxy 330, a web server 340, and an advertisement server 360. However, some components of the advertisement providing system may be omitted. Also, the signal flow of FIG. 8 may be a signal flow subsequent to the signal flow of FIG. 3 .

Referring to FIG. 8 , in ⑥, the client 310 may request an additional advertisement from the proxy 330 server. The additional advertisement request may include the address of the advertisement server 360 providing the additional advertisement and HTML attributes for specifying the additional advertisement. According to one embodiment, the client 310 may encrypt the additional ad request and transmit the encrypted additional ad request to the proxy 330 in order to avoid blocking the ad call. Additional ad requests may be forwarded to proxy 330 via CDN 320 .

In ⑦, the proxy 330 may request advertisement information from the advertisement server 360 corresponding to the received advertisement request. In ⑧, the proxy 330 may receive advertisement information from the advertisement server 360 . Here, the advertisement server 360 of FIG. 8 is a server managed by the operator of the advertisement providing service according to the present disclosure, and may be a separate server from the advertisement server 350 of FIG. 3 . Hereinafter, the advertisement server 360 of FIG. 8 may be referred to as its own advertisement server 360 .

And in ⑨, the proxy 330 may transmit advertisement information received from its own advertisement server 360 to the client 310 . Here, the advertisement information may be encrypted by the proxy 330 and transmitted to the client 310 .

In ⑨, the client 310 may receive additional advertisement information from the proxy 330 and/or the CDN 320. And the client 310 may output the received advertisement. Here, if the advertisement information is encrypted, the client 310 may decrypt and output the received advertisement.

That is, referring to FIG. 4 , the client 310 exchanges an advertisement request and an advertisement response with its own advertisement server 360, and may not exchange a separate signal with the web server 340 to obtain additional advertisements. there is.

Here, operations of devices due to the flow of signals exchanged between the client 310 executing at least one command of the recovery script in the advertisement providing system and components of the advertisement providing system may be as described below.

9 is a flowchart illustrating the operation of each component in the advertisement providing system.

Referring to FIG. 9 , the advertisement providing system may include a client, a CDN, a proxy, a web server, and an advertisement server. However, some components of the advertisement providing system may be omitted.

In step S511, the client may execute an advertisement blocking function. When the advertisement included in the TTP response is blocked by the advertisement blocking function of the client, the client may execute at least one command included in the recovery script of the modified HTTP response.

In step S513, the client may generate an advertisement request for requesting a separate advertisement, and may encrypt the generated advertisement request.

In step S515, the client may transmit an encrypted advertisement request to the proxy. Here, the encrypted advertisement request may be forwarded to the proxy through the CDN.

In step S517, the proxy may decrypt the encrypted advertisement request received from the client.

In step S519, the proxy may request an advertisement from its own advertisement server corresponding to the decrypted advertisement request.

In step S521, the external advertisement server may transmit advertisement information corresponding to the advertisement request to the proxy. Advertisement information transmitted by its own advertisement server may be advertisement content itself. That is, the self-advertising server may be an object to be displayed on the client, such as an image, text, or sound of advertisement content.

In step S523, the proxy may encrypt advertisement information obtained from an external advertisement server.

In step S525, the proxy may transmit encrypted advertisement information to the client. Here, the encrypted advertisement information may be forwarded to the client through the CDN.

As a result, the client can receive encrypted advertisement information. The modified HTTP response and/or repair script may include an area directed to display encrypted advertising content. The client may decrypt the encrypted advertisement information by executing at least one command of the recovery script.

Accordingly, the client can output the decrypted advertisement information.

Here, each operation of components of the advertisement providing system including a client executing at least one command of the recovery script may be as described below.

10 is a flowchart illustrating a recovery script execution operation of a client of the advertisement providing system.

In step S901, the client that has blocked the first advertisement information may generate a request for second advertisement information. Here, the second advertisement information may be a separate advertisement from the first advertisement information. Also, the advertisement server managing the second advertisement is a self-advertising server managed by the operator of the advertisement providing service, and may be a separate server from the advertisement server managing the first advertisement.

In step S903, the client may encrypt the generated second advertisement information request. The client may encrypt the second advertisement request and modify at least one information of a domain of the advertisement request, a request method, and a request address. For example, the client may modify the domain of the second advertisement request to the domain of the server that sent the HTTP response. Accordingly, the domain of the second advertisement request may be the same as the domain of the server transmitting the HTTP response.

In step S905, the client may transmit an encrypted second advertisement information request to the proxy. When a client executing the advertisement blocking function requests advertisement information from an external advertisement server, the advertisement information request may be blocked by the advertisement blocking function of the client. On the other hand, encrypted ad requests may circumvent the client's ad blocking capabilities. As a result, encrypted advertisement requests can be sent to external servers such as proxies.

11 is a flowchart illustrating the operation of a proxy of an advertisement providing system that has received an encrypted advertisement request.

In step S1001, the proxy may receive an advertisement request from a client. Here, the advertisement request may be an advertisement request encrypted by the client.
