Abstract

The present invention relates to an internet advertising billing system that handles reasonable billing through the issuance of cookies even for the occurrence of fraudulent clicks on advertisements posted on a website. The Internet advertisement billing system of the present invention issues a first cookie to the terminal of the Internet user, in which an identifier and an issuance time are recorded for the Internet user's access to the website where the advertisement is displayed, and the advertisement click information is received. 1 If it is determined that the issuance time has not passed a predetermined time from the cookie, it is set not to process billing. If it is determined that the publication time has elapsed from the published first cookie, a second cookie, which is set to be charged only once for duplicate clicks, is issued to the Internet user terminal within the session time, and the click on the advertisement displayed within the session time is executed. If this occurs, it is set not to handle billing. Accordingly, the billing is determined after a certain time elapses after the first time the Internet user accesses the site. Therefore, the billing process is not only reasonable for intentional duplicate clicks by deleting or editing cookies, but is also charged only once even for duplicate clicks within the set session time. Helps prevent advertising spend.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internet advertising billing method and system, and more particularly, to an internet advertising billing method and system for billing an advertiser using a cookie issued to an internet user terminal.

With the development of the Internet, various websites are appearing exponentially around the world. In other words, various websites are being opened for other reasons such as public relations, community means of hobbyists, and individuals voluntary network participation in companies or organizations. With the emergence of so many websites, website operators have become aware of the need to advertise their websites to the public, and ordinary Internet users (where ordinary Internet users are people who use the Internet for simple reasons such as searching for information, In the following, they are called Internet users, and they have come to demand ways to access their desired websites more quickly among countless websites. As a result, a number of Internet sites are categorized and displayed in various fields, and a search box is provided, and a search service is provided to make it easier to visit a desired website by providing a list of keywords related sites based on keyword input by Internet users. Sites have emerged. These search sites are also called portal sites because they serve as a gateway to Internet users on the Internet.

As portal sites grow exponentially, they are attracted by more Internet users, which opens up new business opportunities. In other words, it is possible to make money by exposing advertisements of advertisers who want to promote their website to Internet users who visit the portal site.

In the early days of Internet advertising, banner exposure linked to advertiser's website was mainstream. However, with the evolution of the Internet, various internet advertising models were developed to increase the effectiveness of advertisement.

The conventional technology of the newly appeared Internet advertising model is applied to the 'computer communication network search engine' filed by Overture Services Inc. (hereinafter referred to as 'Overture Inc.') (Korean Patent Application No. 10-2002-0045944). Location and price protection of the list of search results generated by the system and method. Overture's system provides a keyword search tool and a bidding tool to set usage rights for search keywords of Internet users so that advertisers can search and register keywords related to their website. The system provides a list of related keywords as a result of the search through the keyword search tool, allowing the advertiser to select related keywords and bidding desired search keywords through the keyword bidding tool. The system is set such that a list of websites is placed in a predetermined position as a keyword search result of an Internet user according to the advertiser's search keyword bid amount / request ranking for the keywords bid from the advertisers. In addition, the system calculates an advertisement cost according to a click of a hypertext, which means a visit of an Internet user, from the list of websites displayed according to the bid amount (Cost per Click).

However, the CPC method as described above has a fatal problem of 'negative click' which can cause unnecessary expenses for advertisers. In other words, the CPC method is charged according to the advertising effect, so unlike the existing impression-based billing method, advertisers are currently using it as their most preferred billing method. However, by intentionally repeating the click, the advertising effect can be promoted. there is a problem. This fraudulent click is a deadly risk that can undermine the CPC billing system, so many companies are building a system to prevent it, but it is difficult to prevent 100%. In addition, the CPC method requires an intermediate server for counting clicks at the moment when a user clicks a search link because it is difficult to count clicks in web analytics. At this time, the intermediate server records each time one signal comes in, and counts the number of clicks through the aggregation. In this process, a separate platform is required to prevent fraudulent clicks, which adds to the cost of building the system. In addition, advertisers are required to pay a large number of unintended clicks or malicious clicks by the same user. There is a problem that must be taken inefficient.

Recently, in order to prevent intentional fraudulent clicks, a method of processing Cost per Cookie has been proposed. A cookie is string information that is previously transmitted and stored in a web browser in order to request specific information from a web server. In this case, the billing method per cookie should not be issued twice within a certain time period. Therefore, only one cookie will be charged for one cookie even if the user clicks through the same terminal several times. It is called as Cost per Visitor (hereinafter referred to as CPV).

As a conventional technology of CPV, a method and apparatus for detecting invalid clicks in an Internet search engine filed by NHN Co., Ltd. (hereinafter referred to as NHN Corporation) (Korean Patent Application No. 10-2003-0017233) You can find it at NHN's invalid click detection method provides a search result page in response to a searcher's request through a search engine, and when a searcher clicks a search item on the search result page, the site identification information corresponding to the search item and the searcher's web It is determined that invalid clicks within a predetermined time are invalid from cookie information stored in the browser. In addition, the content of the NHN patent application includes the content to obtain the site identification information corresponding to the IP address and the search item of the client and to determine that the invalid click occurrence within a predetermined time from the obtained information is invalid. In this case, each search item displayed on the search result page becomes an advertisement exposed at a position set according to the purchase amount of the advertiser.

 However, the NHN company's invalid click detection method has a problem in that when a user deletes a cookie for malicious purposes or attempts to click illegally by changing an IP address, similarly, inefficient charging may be generated. In addition, there is a fear that fraudulent clicks may be generated through an editing operation for manipulating the time of the cookie or the like.

An object of the present invention is to delete or edit cookies for advertisements placed on the Internet by avoiding charges within a set time when an Internet user accesses an advertisement posted on a website in order to solve the above problems. The present invention provides an internet advertising billing system and method for more efficiently executing billing even when a fraudulent click occurs.

Internet advertising billing method according to the present invention for achieving the above object is the step of issuing a first cookie to the terminal of the Internet user recorded the identifier and issuing time for the access of the Internet user to the website where the advertisement is posted Determining whether or not a predetermined time elapses from the first cookie when the advertisement click information displayed on the website is received, and if the predetermined time elapses from the first cookie issuance time. Determining whether or not to charge. In this case, the first cookie is encrypted and issued to prevent editing of an intentional fraud clicker.

The determining whether to charge for the advertisement click comprises setting a second cookie having a predetermined session time so as not to be issued within the session time, and issuing the first cookie for the advertisement click. Issuing the second cookie to the terminal of the Internet user if it is determined that the period of time has elapsed; and the second issue issued to the terminal of the Internet user when the advertisement click information is received from the terminal of the Internet user. Determining whether to charge according to the record information of the cookie.

The issuing of the second cookie may include determining whether a second cookie previously issued in the terminal of the Internet user exists before issuing the second cookie, and issuing the second cookie in the terminal of the Internet user. If the second cookie is present, determining whether the session time of the issued second cookie has elapsed, and determining whether the session time of the issued second cookie has elapsed. And deleting the issued second cookie and issuing a second cookie.

Determining whether or not the billing step is to determine whether the cookie of the same advertisement as the clicked advertisement exists in the second cookie, if it is determined that the session time of the second cookie is not elapsed, and the second If the cookie of the same advertisement as the clicked advertisement does not exist in the cookie, the step of charging once.

Internet advertising billing system according to the present invention for achieving the above object is issued to the terminal of the Internet user, the first cookie recorded the identifier and the time of publication for the access of the Internet user to the website where the advertisement is posted, A web server for determining whether a predetermined time has elapsed from the first cookie when the click information is received from the internet user terminal for the advertisement displayed on the website, and managing a database constructed according to the advertisement related information. And a billing processing server configured to determine whether to charge according to the click on the advertisement according to whether or not the predetermined time of the first cookie issuance time has passed through the web server.

If it is determined that the issuing period of the first cookie has passed a predetermined time for the click on the advertisement, the web server recalls a second cookie having a predetermined session time which is not set to be issued repeatedly within the session time. Is issued to the terminal of the Internet user, the billing processing server determines whether or not to charge according to the information of the second cookie issued to the terminal of the Internet user when the advertisement click information is received from the terminal of the Internet user.

Here, when there is a second cookie previously issued in the terminal of the Internet user, the web server deletes the second issued cookie if the session time of the second issued cookie has elapsed, and the new second cookie. Issue a.

If the web server determines that the session time of the second issued cookie has not elapsed, the web server determines whether a cookie of the same advertisement as the clicked advertisement exists in the second cookie, and the billing processing server determines the second cookie. If the cookie of the same advertisement as the clicked advertisement does not exist at is set to be charged once.

Internet billing method and system as described above, even if the cookie is intentionally deleted and clicked on the advertisement, the billing is not made for a predetermined time of the first cookie first issued, thereby eliminating the concern of paying unnecessary costs due to the fraudulent click of the advertiser. have.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

1 is a network configuration to which the Internet advertising billing system according to the present invention is applied. In the network, the Internet user / advertiser terminals 110, 120, 130, the Internet advertisement service system 300, and the Internet advertisement billing system 200 are organically connected through the Internet 150.

The Internet user / advertiser terminals 110, 120, and 130 are provided by the Internet advertisement service system 300 through various Internet connection tools such as the desktop computer 110, the personal digital assistant (PDA) 120, the notebook 130, and the like. You can access a website that you do. The Internet advertisement service system 300 includes a search engine web server and provides a list of websites of advertisers who have purchased search keywords in order to advertise their websites for keyword searches of Internet users. Each website list contains summary information about the website. The Internet advertising billing system 200 is a type of advertising billing that charges for hypertext clicks that mean advertisers visit a website in a search result list presented by an Internet user in the form of a hyperlink. The Internet advertising billing system 200 is preferably operated in conjunction with the Internet advertising service system 300, but can be operated as a separate independent system. Internet advertising billing system 200 should be designed to share communication information with the Internet user terminal from the Internet advertising service system 300 to operate as a separate independent system.

2 is a block diagram of an Internet advertising billing system according to an embodiment of the present invention. The system includes a search engine web server 210, a billing processing server 220, and a database server 230.

The search engine web server 210 issues a first cookie encrypted with an identifier and issuing time to the terminal of the Internet user to access the Internet user's access to the website where the advertisement is displayed, and clicks on the advertisement displayed on the website. When the information is received, it is determined whether a predetermined time has elapsed from the first cookie issued to the terminal of the Internet user. In addition, the web server 210 may transmit a second cookie having a predetermined session time set such that the first cookie is not repeatedly issued within the session time if the first cookie is issued for a click of an advertisement. Issued to the terminal. At this time, if there is a second cookie previously issued in the terminal of the Internet user, if the session time of the second issued cookie has elapsed, the second issued cookie is deleted and a new second cookie is issued. If the session time of the second issued cookie has not passed, it is determined whether a cookie of the same advertisement as the click advertisement of the Internet user exists in the second issued cookie.

The billing processing server 220 determines whether or not the billing is based on the advertisement click according to whether a predetermined time elapses from the first cookie issuing time through the search engine web server 210. In addition, when the advertisement click information is received from the terminal of the Internet user, the billing processing server 220 determines whether to charge according to the second cookie issued to the terminal of the Internet user. That is, if the advertisement click information of the Internet user is received within the session time of the second cookie, if the cookie of the same advertisement as the clicked advertisement does not exist in the second cookie, it is charged once.

The database server 230 registers and manages advertisement related information, cookie issuing information, and billing information according to an advertisement click of an Internet user in a database, and registers and manages information derived from each registered information. Here, the advertisement related information includes various information for advertisement such as advertiser information, advertisement amount information, IP address information of advertiser site, advertisement summary information of advertiser, and the like. In addition, the billing information includes a variety of information for billing, such as the number of clicks on the advertisement of the Internet user, the account information of the advertiser, the amount information of the advertiser, the balance information. In addition, the cookie issuance information includes general information regarding issuance of cookies such as issuance information of the first and second cookies and identification information of the first and second cookies.

The Internet advertising billing system 200 calculates a cost per visitor (CPV) by issuing a cookie. However, as mentioned in the related art, the conventional CPV charging method may expose a risk of malicious fraud clicks such as deleting or editing a cookie, so that the system 200 may use the first cookie as an element of the identifier and the issue time. It is operated in such a way that it is identified and does not charge for a certain time from the first cookie issue time. In addition, the system 200 operates to process only one charge for duplicate clicks within the session time of the same advertisement using a second cookie after a predetermined time elapses after issuing the first cookie. That is, since the billing is determined after a predetermined time elapses through the issuance of the first cookie, the system 200 can perform a reasonable billing process even if an intentional fraud click through deleting or editing the cookie occurs.

3 is a flow chart illustrating in more detail the charging process of the advertising billing system according to an embodiment of the present invention. When the Internet user first accesses a website for searching (S310), the system 200 issues a first cookie (S320) in which an encrypted unique number and an issuing time are recorded in the terminal of the Internet user. Subsequently, when the Internet user clicks on the advertisement displayed on the search result page (S330), the user obtains the publication time information from the first cookie issued to the user's terminal and determines whether a predetermined time T1 of the publication period has elapsed (S340). . Then, it is determined whether or not the billing is based on the result of the determination (S340) (S350).

According to the result of the determination (S340), the step of determining whether to charge (S350) is determined not to charge for the click on the advertisement of the Internet user when the predetermined time T1 has not elapsed as a result of the determination (S340) (S359). As a result of the determination (S340), if a predetermined time T1 has elapsed, it is determined whether a second cookie having a predetermined session time T2 exists in the user's terminal exists (352). In this case, if the second cookie does not exist in the user terminal, the second cookie is issued to the user terminal (S353), and the user charges once for the user's click on the advertisement (S358). However, if the second cookie exists in the terminal of the user, it is determined whether the session time of the previously issued second cookie has elapsed (S354). If the session time T2 of the previously issued second cookie has elapsed, the second cookie is deleted (S355), and a new second cookie is issued (S353) to newly apply the session time T2. If the session time T2 of the previously issued second cookie has not elapsed, it is determined whether a cookie of the same advertisement as the currently clicked advertisement exists in the second cookie (S356). At this time, if there is a cookie of the same advertisement as the clicked advertisement in the second cookie, the charging is not performed (S359). If not, the charging process is performed (S358).

In the charging process as described above, the time T1 and T2 set in the first and second cookies may be set according to a decision of the system operator, and it is preferable that T1 has a relatively long time compared to T2.

The process of the above Internet advertising billing system assumes that the initial click time (T1) is 30 minutes, for example. After 31 minutes, you will be able to click, click, and delete the cookie. When the cookie is issued again, the existing first cookie is deleted, so the system recognizes it as the 'first cookie' and again charges the click only after 30 minutes have elapsed.

Therefore, if the cookie is intentionally deleted, only two clicks occur in an hour, and even if a fraudulent click is attempted for 24 hours, only 48 clicks can be generated, which can effectively prevent abusing through cookie deletion. In addition, fraudulent clicks due to cookie editing are virtually impossible since cookies are issued encrypted.

 4 is a diagram illustrating a billing process for an advertisement click that occurs after a predetermined time elapses when a first cookie is issued. If the session time of the second cookie is set to 3 minutes, the system 200 determines that when users A, B, and C each click on the advertisement A of the advertiser b, 1) the user first before the web server issues a cookie. The client 100 checks if there is a cookie older than 3 minutes. If there are cookies older than 3 minutes, delete them. 2) If the cookie is within 3 minutes, check whether there is a cookie of the same advertisement A. 3) If there is a cookie of the same advertisement A (because it occurred by clicking within 3 minutes), it is charged and only the cookie last time is updated. Charges if Ad A's cookie is missing. Even if the user A generates several clicks within three minutes from his or her notebook 100, the system 200 issues only one cookie and only counts the cookie so that only one charge is generated. How long the session takes is a matter of advertising platform operation.

As another example, even if user B clicks on user A's notebook 100 while the user A makes several clicks within three minutes of the user's notebook 100, only one charge is made since the cookie is already issued. Similarly, in the case of user C, when the user clicks on the advertisement using the user A's terminal, the charge is not duplicated. However, in the previous two examples, if a click occurs after the session time, a cookie is generated once again and billing is performed. This not only solves the problem of click fraud, but also prevents unnecessary clicks from the advertiser.

Meanwhile, in FIG. 4, the charging method for a plurality of clicks for one advertisement generated within a specific time in one client (computer terminal) has been described. As another example, a plurality of different advertisements are clicked on one client. The following is a description of the charging method.

Internet users' browsers limit cookie storage to 255 bytes per DNS. Therefore, when the user clicks on the number of advertisements exceeding the cookie storage capacity within 3 minutes, the browser may continuously update the cookie information, thereby charging the same advertisement. For example, if a user clicks on advertisement A, a cookie is issued, then clicks on dozens of advertisements other than advertisement A within three minutes, removes advertisement A from the user's cookie storage, and then the cookie is issued and billed again. In this case, by checking the time with the session ID, clicks within 3 minutes can be again classified, and whether or not to charge or not charged.

As described above, the billing method primarily determines cookies in the web server, and is much faster and cheaper than the case of going to the DB server to determine the cookies. In addition, abusing clicks can be prevented by identifying the second session with the secondary session ID.

In the above Internet advertising billing system, billing is determined after a certain time has elapsed since the first time an Internet user accesses the site. Therefore, even if an intentional fraudulent click through deleting or editing a cookie occurs, the billing process is not only reasonable but also duplicated within a set session time. Even if a click occurs, it is charged only once, thereby preventing an advertiser from spending unfairly on advertising.

In addition, since fraudulent clicks are substantially prevented, a mistake visitor is visited to the advertiser's website, so that the advertiser can obtain more efficient advertisement effect, and the system operation side can reduce unnecessary traffic generation, thereby obtaining system stability.
