Description

FIELD OF TECHNOLOGY

[0001] The present invention relates to systems for presenting advertising information to Internet users and improves the distribution efficiency of advertising and information materials on the Internet by counteracting the means of blocking advertising on Internet resources (websites).

BACKGROUND

[0002] The demonstration of advertising to subscribers (users) of a communication network is one of the significant sources of income for the operator and / or owner of an Internet resource (website). The use by subscribers of the network of various ways to prevent the demonstration of advertising messages (ad blocking) reduces the number of ad impressions to subscribers, which in turn leads to a significant decrease in the income of both operators (owners of communication networks) and owners of websites on whose pages advertising is displayed. Ad blocking can also lead to a violation of the terms of contracts between the operator / owner of the site and the advertiser, as one of the essential conditions of such contracts is the achievement of the number of demonstrations of advertising messages agreed upon by the parties for a certain period of time, and, consequently, to the material damage of the site operator / owner.

[0003] Thus, the problem of ad blocking is relevant around the world - a study conducted by PageFair and Adobe Systems Inc. In the summer of 2015, it showed that about 45 million users in the United States used various means of ad blocking, which is almost 50 percent more than the year before. According to experts, the use of ad blocking has led website owners to receive less than $ 22 billion in advertising revenue.

[0004] Known systems and methods for counteracting ad blocking on the Internet, based on identifying the means of ad blocking installed by the user and forcing the user to either disable them or add this site to the so-called “white list” (t. e. a list of addresses of sites whose advertising will not be blocked by appropriate means of blocking), or log in through existing user accounts on social networks, etc. resources. Such methods are implemented both by special software (for example, AdGuard, Adblock Browser, etc.), and various add-ons / plug-ins and browser extensions (for example, Adblock Plus, uBlock, Ghostery, etc.).

[0005] An option of this method is to acquire the right to display advertising from developers of advertising blocking means (as a result of payment, the owner of the blocker program includes the resource in their lists, and thus the blocking means of advertising does not perform actions to block advertising in relation to this resource / website )

[0006] The disadvantages of this method of countering ad blocking are:

a) low level of effectiveness in counteracting advertising blocking means: as a rule, one or several ways to implement blocking can successfully block advertising even when using these means;

b) reducing the speed of user access to the website and receiving the requested information;

c) forcing the user to take additional actions to go to the website of interest to him, which may lead to the user refusing to visit the website as a whole and, consequently, to the absence of advertising to this user on this website.

[0007] Also known are systems and methods of counteracting ad blocking based on masking requests under a CDN network (Content Delivery Network). However, their application has limitations associated with user identification (user definitions on the side of the advertising provider), since in this case the ability to identify users by conventional identifiers (from cookies) is lost, which requires refinement of the solution on the side of the advertising provider. User identification is a prerequisite for targeting advertising and informational messages, which, in turn, is one of the most essential requirements of advertisers and advertising services.

[0008] In addition, methods are known for preventing blocking of advertising content based on DNS spoofing. One of them, for example, is disclosed in the document US 20160239880. The main disadvantage of this method is its low efficiency when used with the purpose of anti-blocking advertising, since modern means of blocking advertising can circumvent this decision and ensure that advertising is not displayed.

[0009] Also, in order to guarantee the display of advertising, a static advertising method is applied that does not require interaction with the advertising service - HTML tags of such advertising are not determined by blocking means as advertising and, accordingly, blocking is not applied to them. The main disadvantage of this method is the inability to interact with advertising services, which has the consequence of significant restrictions for the owner of the website in the field of interaction with advertisers and the placement of advertising on their website. This method also does not allow the targeting of advertising and informational messages, which from the point of view of advertisers and advertising services is a significant drawback of the Internet resource in modern conditions.

[00010] Document US20160253718 A1 discloses a package for preventing blocking of advertising content on a network user terminal, comprising an obfuscation unit placed on a requested resource, downloaded together with the content of the requested page and configured to verify the use of advertising blocking means on the user terminal in the case of detecting such means - identifying a request code for advertising content in the code of the requested page, obfuscating the specified code, transmitting data about the obfus cations to the block for processing advertising requests. The advertising request processing unit disclosed in US20160253718 A1 is located on a remote server and is configured to process obfuscated advertising content requests by decrypting, executing, and transmitting the advertising content code to the obfuscation unit. At the same time, from the means for preserving the targeting of advertising content in document US20160253718, only the possibility of storing a cookie with information received by the processing unit of advertising requests from the advertising service is mentioned on the user terminal.

[00011] However, the complex and the corresponding method for preventing the blocking of advertising content disclosed in US20160253718 slow down the loading of content in the user's browser, take up the resources of the user’s terminal, and the effectiveness of the proposed targeting tools can be nullified if third parties do not record cookies.

[00012] Thus, there is a need for means to prevent blocking of advertising content embedded in the requested page by means of a request code for advertising content from a server with the domain name of the advertising service, which are invisible to the user, provide quick loading of the requested content in the user's browser, stably preventing the blocking of advertising content, provide targeted advertising content. The proposed technical solution is aimed at solving these problems, overcoming at least some of the disadvantages of the known means of preventing blocking of advertising content and improving their characteristics, which will be clear from the following description.

SUMMARY OF THE INVENTION

[00013] The essence of the proposed technical solution is to create a complex and method for preventing blocking at least one terminal of a user of advertising content that is embedded in a page requested by a user by means of a code for requesting advertising content from a server with the domain name of the advertising service.

[00014] The proposed technical solution provides a technical result in the form of preventing blocking of advertising content that does not affect the performance of the user terminal and practically does not affect the regular operation of the browser, together with targeting the advertising content received on the side of the telecommunications operator for the specified user of communication services . The proposed technical solution is characterized by high efficiency of preventing blocking of advertising content, regardless of the means and methods of blocking advertising used on the user's device, that is, it is universal in terms of means and methods of blocking advertising, since the advertising content as a result of applying the proposed technical solution is disguised as the content of the requested page .

[00015] According to a first aspect of the present invention, there is provided a complex for preventing at least one user terminal from blocking advertising content that is embedded in a requested page by means of a code for requesting advertising content from a server with an advertising service domain name. The proposed complex is configured to exchange data with a user terminal, the Internet and contains a block for collecting and analyzing cookies, a block for obfuscating requests for advertising content and a block for proxying requests for advertising content. The cookie collection and analysis unit is configured to: collect cookies related to at least one domain of an advertising service at least once for each browser on a user terminal; receive from the network authorization system the MAC address of the user terminal based on the IP address of the user terminal; save the collected cookies in the cookie database in conjunction with the domain of the corresponding advertising service and data providing user identification and including at least the MAC address of the user terminal for its identification; match cookie database records with retrieved user authentication data to determine the most relevant record; retrieving a cookie from the indicated most relevant record as a domain-specific cookie cookie of the browser.

[00016] The obfuscation unit for requests for advertising content is configured to: retrieve data providing user identification from a request received from a user terminal; receiving the code of the requested page, checking for the presence of the code for requesting advertising content in it. When an advertising content request code is detected, the obfuscation unit sends the specified advertising content request to the proxy block of the advertising content requests together with the domain information of the requested page and data providing user identification; receives from the block of proxying requests for advertising content a code for displaying advertising content containing at least one link to an advertising service domain; obfuscates this code and generates the landing page code by replacing the request code for the advertising content with the obfuscated code for displaying the advertising content.

[00017] The block for proxying requests for advertising content is configured to fulfill requests for advertising content received from the obfuscation block and transmit to the obfuscation block the code for displaying advertising content received in response to them.

[00018] In this case, the block for proxying requests for advertising content is configured to, when executing a request for advertising content received from the obfuscation block, use a browser cookie related to the domain of the advertising service, and the obfuscation block is configured to obfuscate the indicated code for displaying advertising content by replacing at least one link to the domain of the advertising service to the link containing the obfuscation tag on the domain of the requested page, as well as with the ability to save data about the correspondence of the indicated links and the transfer to the user of the landing page code

[00019] According to a second aspect of the present invention, there is provided a method for preventing at least one user terminal from blocking advertising content that is embedded in a requested page using an advertising content request code from a server with an advertising service domain name. Moreover, according to the method: collect cookies relating to at least one domain of the advertising service, at least once for each browser used on the user terminal; determine the MAC address of the user terminal or its IP address based on its IP address or MAC address, respectively, and store the collected cookies in the cookie database in conjunction with the domain of the corresponding advertising service and data (UID) that provide user identification and including at least the MAC address of the user terminal; receive a request from the browser to the domain of the requested page; receive the content code of the requested page and identify the code for requesting advertising content in it; extracting the IP address of the user terminal from the request received from the user's browser; retrieving a cookie of this browser related to the domain of the corresponding advertising service from the cookie database on the basis of data (UIDs) that provide user identification; requesting advertising content using the extracted browser cookie to obtain a code for displaying advertising content containing at least one link to an advertising service domain; perform obfuscation of the code for displaying advertising content by replacing therein the indicated at least one link to the domain of the advertising service with a link to the domain of the requested page containing the obfuscation mark; save in the obfuscation table data on the correspondence of the indicated links; generating a landing page code based on the code of the requested page by replacing the code for requesting advertising content in it with an obfuscated code for displaying advertising content; and pass the landing page code to the user's browser.

[00020] The proposed complex and method not only provides the replacement of a domain name in an advertising request, but also retains the targeting of advertising content by providing the necessary communication service cookies for the advertising server when performing requests to the advertising service. At the same time, by masking links to the domain of the advertising service as links to the content of the requested resource, the proposed technical solution significantly increases the likelihood of preventing blocking of advertising content, since the user's browser is not able to determine the obfuscation mark and, therefore, does not distinguish advertising content from the content of the requested page.

[00021] In view of the means used in the proposed technical solution and taking into account the features of currently known means of blocking advertising content, the application of the invention provides a demonstration of advertising content to a user regardless of the means and methods of blocking advertising used by him, including as special software ( for example, AdGuard, Adblock Browser, etc.), as well as various add-ons / plug-ins and browser extensions (for example, Adblock Plus, uBlock, Ghostery, etc.).

[00022] The embodiments of the proposed technical solution disclosed in this description are provided for a better understanding of its features and advantages and do not limit its scope as defined by the independent claims.

DETAILED DESCRIPTION OF THE INVENTION

[00035] The invention relates to anti-ad blocking means for telecom operators having the ability to use WebAuth authentication in their networks. The proposed complex and method are fully implemented provided that users are identified through cookies and the HTTP protocol is used for advertising requests.

[00036] Used in the present description, the terms "carrier", "provider", "network owner" means a communication service provider that implements access to the Internet. The complex proposed in accordance with one aspect of the present invention relates to the software and hardware of a communications service operator, and can also be partially implemented on the side of the resources requested by the user (various web servers). The terms “cookies” and “cookies” as used below mean a cookie or cookies, respectively.

[00037] The terms “subscriber device”, “user terminal”, “network user device” mean a device with which the user connects to the provider's network and accesses the Internet.

[00038] The terms "user identification" refers to the identification of a particular device and, in some cases, browser, through which requests are sent from a user terminal of a communication service.

[00039] The terms "advertising platform", "advertising service" mean elements of a system of methods and tools, including hardware and software, providing the distribution and demonstration of advertising information messages and other advertising content on the Internet.

[00040] The proposed technical solution can be successfully applied to interact with advertising services operating according to the following standard algorithm:

- in the HTML code of the page generated for the user on the website, the owner of which has entered into an agreement to display advertising with at least one advertising service, at least one request to a specialized server (“advertising service”) providing advertising is embedded, eg:

<script type = 'text / javascript'> googletag.cmd.push (function () {

var slot_billboard = googletag.defineSlot ('/ 52237517 / RBCMain_Billboard', [1160, 250], 'div-gpt-ad-1432742391349-0'). addService (googletag.pubads ()); rbc_dfp.addSlot (slot_billboard, false);

- to receive the specified advertising content, the user's browser sends a request to the advertising service, including user information (cookies), in accordance with this code;

- the advertising service returns to the browser the code of the advertising content in response to the specified request;

- The browser displays the advertising content to the user in accordance with the rules determined by the advertising service.

[00041] Implemented according to the proposed method for preventing blocking of advertising content, the principle is as follows. In the network of the communication services operator, a complex is implemented to prevent blocking of advertising content, which processes all requests of the terminals of users of communication services and is configured to identify user terminals at least once for each browser used on the terminal of a network user, collect cookies and their saving in a special database in conjunction with data (UID) that provide user identification, then use this data to obtain an ad display code th content for that user from the advertising service, obfuscate the code display advertising content and advertising content to replace the code in the code query the content of the requested user page on the obfuscated code display advertising content. At the same time, the code for displaying advertising content is obfuscated by “masking” it as the content of the requested web page with entering into the obfuscation table the correspondence of the obfuscated and source codes so that the complex, when processing a request for such content, is able to recognize the obfuscated code and fulfill the corresponding request for displaying advertising content . Thus, the request for advertising content is “disguised” as a request for the content of the web page requested from the user's browser, that is, it is obfuscated so that it cannot be recognized by means of blocking ads that are focused on blocking requests to the domains of advertising services. In addition, the proposed complex is also configured to process the indicated obfuscated requests for advertising content while retaining the targeting functions by fulfilling the request for advertising content from the advertising service in conjunction with sending cookies that correspond to cookies of the specified user's browser for the domain of the specified advertising service.

[00042] According to the invention, when a user enters a link of a requested web page in a browser, and a browser of a user terminal connected to the network of a communication service provider sends a request to the domain of the requested resource, the ad blocking prevention complex intercepts the user's browser request and executes it and forms a landing page in which the code for displaying advertising content is obfuscated and to which the request of the user's browser is redirected. This landing page is formed by a complex to prevent blocking of advertising content by replacing the code for requesting advertising content from the advertising service in the code of the requested page with an obfuscated code for displaying advertising content. For the user's browser, the landing page transmitted to him does not differ from the requested web page, except for the way of marking (coding) advertising content.

[00043] The operation of advertising services (PC) is based on marking users with various special identifiers in cookies associated with the domain name of the advertising service. When the user first accesses the PC (with a request to a domain, for example, adfox.ru), the response to his request will contain special headers (setcookie), which the browser on the user's terminal interprets as a request to save certain information in the browser cookies database. Usually, a unique user identifier for the domain and the date of the last access are stored as such data. The next time the user terminal accesses the PC domain from the same browser, the browser will automatically substitute in the request headers what was stored in the cookie at the previous stage. This is the basic functionality of conducting a network user session, which is provided by the settings of the PC.

[00044] So that the advertising service can return the correct targeted advertising message (aimed at the network user in question), the header of the request for advertising content sent to the domain of the advertising service must contain the user's browser cookies corresponding to the domain used by the advertising service ( for the purpose of identifying the user and determining his parameters).

[00045] As a standard, in the HTML-code of the resource page included by any PC in the advertising display system, there are requests with the domain name of this PC, for example, “adfox.ru/advertising.ru”, by which the blocking means can recognize this request as advertising. Typically, a request for advertising content is sent directly from the user's browser by directly accessing the advertising services. This method allows the means of ad blocking available on the user's terminal to determine the request as advertising and block it.

[00046] In order to avoid recognition of such a request as advertising, it is possible to encrypt only the link, but leave the domain, then it will look in the same code as “adfox.ru/123abcd”, that is, only the path on the domain of the advertising service is encrypted. But in this case, the request can be easily recognized as advertising by the presence of the domain name of the advertising service.

[00047] For more reliable obfuscation, it is preferable to change the DNS records and send advertising requests to the proxy server (for example, if by default the domain adfox.ru corresponds to 1.2.3.4, then the proxy server can send a request to this domain to 10.0.0.1) . But the cookies needed by the PC to target advertising content are associated with the domain to which advertising requests are sent (in this case, adfox.ru), therefore, if the ad anti-blocking system replaces the domain name during the processing of the advertising request, then the automatic substitution function of the saved data is not implemented and, therefore, the PC cannot understand who exactly is applying for advertising, when the user last applied (frequency targeting), etc. In the proposed technical solution, a certain user profile associated with its identifier is formed on the side of the communication service provider, and this profile is used to target advertising for this user. To solve this problem, the proposed technical solution provides for the collection of user cookies for predefined domains of advertising services, storing them in a cookie database and matching cookies and domain names, which is of fundamental importance for the anti-blocking system. Without such functionality, the obfuscation unit and the proxy module do not fulfill their tasks and it is not possible to simply change the domain name in the request for advertising content and preserve the entire functionality of the advertising service without taking into account these aspects of the means of counteracting ad blocking.

[00048] To prevent blocking of advertising content, according to the proposed technical solution, when a network user accesses a domain page, for example, abcd.com, on which a request for advertising content from the PC is embedded, containing a link, for example, “adfox.ru/123abcd”, this link is replaced, for example, with "abcd.com/123abcd". At the same time, the request generates cookies associated with the requested domain abcd.com, but since the anti-blocking system includes a cookie database, which can be used to establish the conformity of cookies and domain names, the proposed complex provides a definition of which cookies of the PC domain ( for example, adfox.ru) are associated with cookies of the abcd.com domain (the required cookies of the PC domain can be obtained on the basis of any possible identifier - for example, the MAC address of the user terminal, IP address, other cookies) and replacing the domain name in the ad display code a lot of content in a way that ad-blocking tools do not recognize the request as "advertising".

[00049] The proposed technical solution (see Fig. 1) involves requesting advertising messages from the server (4) of the advertising service via an HTTP GET request from the module (9) of proxying advertising requests that is part of the proposed complex (2) to prevent blocking of advertising content. According to the invention, in order to comply with the targeting conditions for advertising content, network users are identified in advertising services by matching (“matching”) various data (UIDs) that provide network user identification (for example, but not limited to, unique user identifiers for a domain, cookies , MAC addresses of the network user terminal and other available data providing user authentication) and settings of the advertising service (advertising demonstration system -Information messages being external to the hardware and software services provider).

[00050] The complex (2) (see Fig. 1) for preventing blocking at least one terminal (1) of a user of a network of advertising content is organized on the side of the telecom operator or, in some embodiments, on the telecom operator’s side and partially on the side the requested resource (3) and, according to the invention, all requests for content from the terminal (1) of the user of communication services pass through the complex. When a user at terminal (1) requests a web page located on any requested resource (3) and containing advertising content embedded in the form of a code for requesting advertising content from the server (4) of an advertising service, such a request is processed through a complex (2 ) The complex (2) for preventing the blocking of advertising content contains: a block for the collection and analysis of cookies containing a proxy server (5), a module (6) for collecting cookies and a module (7) for analyzing cookies; block (8) for obfuscating advertising requests and block (9) for proxying advertising requests.

[00051] In the framework of the implementation of the proposed technical solution, the first task is to identify network users. When a user (subscriber) connects to the network of a telecom operator from any device (phone, tablet, laptop, etc.), this device (terminal (1)) automatically receives an IP address issued dynamically or statically - this is an obligatory function of the network working over TCP / IP. In the case of a static network, user authentication occurs by IP address. In the case of a dynamic network, including Wi-Fi networks, IP addresses are assigned dynamically by the DHCP server (11) (see Fig. 2), therefore, to identify the user, you must additionally use the MAC address that the system receives from the IP address through the IP-MAC database (12) created by the DHCP server on the network and which determines the correspondence between the IP address and the MAC address of the user terminal. In this case, the MAC address serves as an identifier that allows you to separate requests from different user terminals. Thus, for the correct formation of the landing page, complex (2) interacts with the IP-MAC data base (12) to obtain a bundle of IP addresses with a MAC address that provides identification of the user terminal.

[00052] In the General case, to solve the problem of user identification in the proposed complex provides a call to the DHCP service to obtain the correspondence of the MAC address of the user terminal and its IP address.

[00053] It should be noted that the blocks and modules appearing in the present description are allocated according to the principle of their main functional tasks, while physically they can be implemented in various ways - both together on one hardware-software device, and on different devices located in various locations, for example (but not limited to this), on the side of the telecom operator or on the side of the telecom operator and partially on the side of the requested resource (3). The different physical embodiment of the described functional blocks and modules can bring different advantages to the proposed technical solution, but does not affect the achievement of the claimed technical result and is limited by the set of essential features of the invention based on the functional features of the proposed complex. In general, the IP information and / or MAC address stored in a cookie for the domain of the requested Internet resource (page), as well as the cookie itself, can serve as the data (UID) that provide user identification. In special cases, it is possible to use other data (UID) that provide user identification.

[00054] The user’s request received by the complex (2) is processed by the obfuscation unit (8): the obfuscation unit (8) executes the request, receives the content code from the requested web page from the requested resource (3) and detects the presence of advertising content in it, an advertising content embedded in the form of a request code for a server (4) of an advertising service. After identifying such an advertising content request code, the obfuscation unit (8) sends it together with the domain information of the requested resource and the corresponding cookie to the advertising request proxying unit (9). Having received the address / domain of the page requested by the user, as well as determining, based on the available data, the user identifier (UID) (data (UID) providing user identification), the advertising proxy block (9) requests the cookie analysis module (7) to receive cookies advertising service domain for this user based on available data.

[00055] The request for advertising content and cookie received from the obfuscation unit (8) contains data (UID) that provide user identification (IP or MAC address and / or cookie itself or other data contained in the request). In order to ensure the targeting of advertising content and, accordingly, to ensure the possibility of receiving cookies for this user for the PC domain, a set of tools is used from the proxy server (5), the module for collecting cookies and the module (7) for analyzing cookies (shown for convenience in Fig. 2). While the module (7) for analyzing cookies is activated every time that requests for advertising content are processed, the proxy server (5) and the module (6) for collecting cookies are not necessarily used every time the browser (1) of the user sends a request. Nevertheless, to create an entry in the cookie database at least once for each browser communication service used on the user terminal, the proxy server (5) redirects the request received from the user terminal to the cookie collection module (6). According to various embodiments of the invention, the collection of cookies for domains of advertising services is carried out when the user connects to the network or enters a browser, and can also be carried out in accordance with certain frequency settings. According to one implementation option, as soon as a user logs into a browser to open a page on the Internet, the user terminal (1) sends an HTTP GET request to the network of the telecom operator, while the proxy server (5) (which can be implemented as a firewall with corresponding function) intercepts this request and sends it to the cookie collection module (6). The module (6) for collecting cookies is a special static page containing an initialization code for asynchronous requests to at least one specified server (4) of the advertising service domain. According to a preferred embodiment of the proposed technical solution, the specified static page contains the code of asynchronous requests to those domains of advertising services whose cookies must be received. The indicated asynchronous requests contain a special identifier that is obviously absent in normal advertising requests, due to which they can be recognized and intercepted for further processing by cookies analysis module (7). According to some implementation options of the proposed technical solution, the proxy server (5) can be activated when the user’s terminal (1) first connects to the network: the browser request is redirected to the cookie collection module (6), which leads the browser to the page with initialization code for asynchronous requests to specified PC domains. After these requests are completed by the user's browser and without waiting for a response to them, the browser is redirected to the authorization page, and the indicated asynchronous requests, due to the presence of intermediate request labels in them, are intercepted by the cookie analysis module (7).

[00056] The cookie analysis module (7) comprises a cookie analyzer and a cookie database. The cookie analyzer parses the intercepted requests to retrieve a data bundle from them, which it then stores in the cookie database. This data includes the MAC address of the user terminal, the PC domain, the corresponding cookies, and in some embodiments may also include other data (UIDs) that provide user identification. At the same time, the received cookies for the PC domains are stored in the cookie database in such a way that the cookie database records contain at least “MAC address + PC domain + associated cookies” in the “key-value” format, so that from the aggregate of intercepted intermediate requests the browser of the network user, a comparison is formed between the cookies of various domains of the PC and the MAC address of the request source device (user terminal (1)). In this way, the cookie collection process, which is schematically shown in FIG. 2. According to some implementation options, intermediate requests are intercepted by the proxying module (9), which identifies the user through the IP-MAC database (12) and sends these requests to the cookie analysis module (7), preliminarily supplementing them with other data (if necessary) ( UID) that provide user authentication.

[00057] When there are already records in the cookie database containing the user's cookies for the necessary domain of the advertising service, it is possible to ensure the correct targeting of the advertising content for this user, which is conveniently explained with reference to FIG. one.

[00058] To ensure the advertising content is targeted, the request for advertising content from the server (4) of the advertising service must be performed using the collected user cookies for the domain of this advertising service. The advertising request proxying unit (9), having received the advertising content request, the user's cookie for the requested resource, and the information about the advertising service domain from the obfuscation unit (8), turns to the cookie analysis module (7) in order to obtain cookies from this user for the desired advertising service domain . After the collection of cookies for the user in question is carried out, the cookie database records contain cookies of this user for the domains of advertising services to which asynchronous requests were sent. The cookie analyzer “matches” (compares) the data received from the proxying module (9) with the records of the cookies database and determines the most relevant record. From the indicated most relevant record, the cookie analyzer extracts the cookie for the desired domain of the advertising service and sends it to the proxying module (9).

[00059] Having received the necessary user cookie for the advertising service domain, the advertising request proxying module (9) executes the specified advertising content request from the advertising service server (4) using this cookie. In response to the specified request for advertising content, the proxy module (9) receives from the server (4) of the advertising service an advertising content display code containing at least one link to the domain of the advertising service, and passes it to the obfuscation unit (8). The obfuscation unit (8) obfuscates the code for displaying advertising content by replacing the specified at least one link to the PC domain (for example, adfox.ru) with a link to the domain of the page requested by the user (for example, abcd.com) containing the obfuscation tag, and stores it in obfuscation table correspondence of the indicated links. Then, the obfuscation module (8) generates the content code of the landing page by replacing the request code of the advertising content with the obfuscated display code of the advertising content and transmits the code of the landing page to the user's browser. The specified obfuscated code for displaying advertising content on the user terminal cannot be recognized as advertising, since it actually turns out to be disguised as the main content code of the page requested by the user.

[00060] When processing the landing page code in the user's browser on the terminal, the browser (1) will execute an obfuscated code for displaying advertising content, as a result of which the obfuscation unit (8) of the complex (2) will turn to the obfuscation table to obtain an unfocused code for displaying advertising content, will execute the specified request (in this stage, the server (4) of the advertising service in this case will be used as the usual requested resource, from which the obfuscation unit (8) will receive the advertising content code) and send the advertising content code to the user but.

[00061] Thus, the complex (2) is configured to process browser advertising requests in accordance with the settings of the advertising services due to the fact that it sends the necessary requests (HTTP GET) and cookies received from the cookie analysis module (7) for this user for the domain of the advertising service to the server (4) of the advertising service. In response to these requests, complex (2) receives the necessary advertising and informational messages for this user in accordance with his request and profile, obfuscates them and substitutes the obfuscated code for showing the corresponding advertising-informational message in the code of the target web page requested by the user, instead of the code request advertising content. The code for displaying an advertising information message received from the PC is a combination of HTML markup and JavaScript code, the function of which is to exchange data with the advertising service, download the necessary scripts and ensure that the user displays a specific advertising information message. The complex (2) to prevent blocking of advertising content generates a page code in such a way that the means / methods of counteracting the advertising used on the user's device do not allow identifying this code as advertising.

[00062] Since most advertising services have a system to counter artificial requests, based on filtering requests by the IP address of the advertising source (the address from where the advertisement is requested), to counter such a system, in some embodiments of the proposed technical solution, an additional proxy server module is provided - a block of rotation of IP addresses (which, according to the embodiment shown in Fig. 1, is implemented in conjunction with a module for proxying advertising requests). The function of this module is that every specified period of time it updates the table of NAT translations of the server segment (which contains the proxy server for processing advertising requests) on the border router of the operator’s network, which leads to the proxy server being processed requests for advertising begins to access the server of the advertising service from the new IP addresses from a common user set, thus circumventing the limitations of advertising services.

[00063] According to one embodiment of the proposed technical solution for reducing the load on the elements of the complex (proxy server for processing requests for advertising content), an obfuscation unit (8), which according to some implementation options can be performed on the basis of a web server, configured to add an ad detection script to the code of the requested page. In this embodiment, user requests are processed by default by the web server without the function of counteracting the means of blocking advertising, and when the actions of the means of blocking advertising are detected, this script provides processing of advertising requests to mask the request for the usual content of the requested page. At the same time, at the stage of collecting cookies after sending asynchronous requests to the specified domains of the advertising services, the user's browser request is redirected to the landing page, which, if the user hasn’t found any means of blocking ads, will not contain any obfuscation of requests for advertising content will be the page requested by the user.

[00064] It should be understood that in the present description, in some cases, for simplicity, such terms as a domain / server of an advertising service, a request, a request code are indicated in the singular, but in the wide application of the invention, these concepts are often not unique, that is on the requested page, there may be many codes for requesting advertising content, the cookie collection module may contain a code for asynchronous requests to many specified domains of advertising services, etc. These generalizations, as well as other modifications of the embodiments presented here, are not a departure from the essence of the present invention and provide, to one degree or another, corresponding advantages.
