However, with the recent emphasis on security and privacy protection, it has become difficult to collect information directly from users.

In this regard, a method of collecting information without a direct member registration process has been attempted. As a representative method, information on a user's web use behavior (for example, access site information, etc.) performed on the web through a browser is collected, and cookies are used. The web usages collected by using (Cookie) are classified by user, and the method of extracting user's disposition or interest through analysis of the divided web usages is used.

Here, the cookie is a small record information file installed in the terminal of the user through the server used by the site when the user visits a website, and is also called an HTTP cookie, a web cookie, or a browser cookie. The information contained in this cookie is read each time a user visits the same website and is changed from time to time. It may be used to distinguish different users, but it is not information that can accurately identify a user or device. It is often used for collecting user information as a non-identifying device ID or non-identifying personal information.

These cookies are stored for each domain and may be classified into first party cookies and third party cookies according to their storage and accessibility. First-party cookies are cookies that originate from the same domain as the website you are intentionally accessing. You can write your information in your own domain. Third-party cookies are cookies that are different from the domain you have intentionally accessed. A cookie generated by a domain (third party domain). It is a cookie that can write information to a domain other than its own domain (ie, 1'st party domain).

The advertisement service provider may use the third party cookie to synchronize first party cookies issued by a website operated by one or more other service providers for the same user, and continuously collect user-specific web usage information based on the third party cookie. Can be.

However, these third party cookies are not controlled by the website's privacy policy, and for users who do not trust them, the third party cookie is added to block the use of third party cookies, so third party cookies cannot be used. In addition, it has become impossible to continuously collect user web usage information by synchronizing first party cookies issued by websites operated by one or more other service providers for the same user.

Therefore, even in an environment where third party cookies are not available, a technique for matching cookies issued from a plurality of different web sites for the same user is required in order to continuously collect the web usage information of the user.

Next, the data management server 40 collects web usage information according to the connection of the terminal 20 to the web site provided by the one or more service providing servers 30, and collects the collected web usage information on the web site. Based on the cookies provided, they are analyzed by user.

Finally, the ID matching server 50 is a device for matching the cookies provided by the one or more service providing server 30 and the data management server 40 for the same terminal 30, the non-identification according to the present invention According to the personal information matching method, a first party cookie value generated and provided to a user of the terminal 20 from a web site accessed by the terminal 20 according to a user's intention, and the data management server 40 is connected to the terminal ( The third party cookie value generated for the terminal 20 is matched to collect the web usage information of the web site accessed by 20). The matching result of the ID matching server 50 is provided to the data management server 40 so that the data management server 40 uses the first party cookie value and the third party cookie value matched with the web user information. To accumulate and analyze the user's behavior.

Next, FIGS. 2 and 3 are flowcharts illustrating a method of matching non-identifiable personal information according to the present invention. In the above-described data management system, the non-identifiable personal information matching method shown in FIGS. 2 and 3 is performed through the interworking of the data management server 40 and the ID matching server 50.

Referring to FIG. 2, in order to match non-identified personal information, first, a first image tag calling a first party side in which the user intentionally connects, and a third party side not connected to the intention of the user are called. A second image tag to be set is set (S205 and S215). Here, an image tag is an object that is embedded in a web page that is combined with a cookie to monitor the user's behavior such as using a website or sending an email. Is added via image. These image tags are called various names: Web bugs, web beacons, pixel tags, clear GIFs, and e-mail tracking. With these image tags, a web site operator typically tells users when and how long they are connected, how long they use, what type of browser they use, how to set cookie values, and what their IP address is. Information can be tracked. The present invention is intended to match non-identifiable personal information using such an image tag, and is driven simultaneously when browsing an inserted web page, and the first and second image tags respectively calling first and third parties respectively. To set it. Here, the first party side is a web site corresponding to the domain of the web page called by the user. In the data management system of FIG. 1, the first party side may be any one or more service providing servers 30. As the domain is not intentionally called, in the present invention, the data management server 40 to collect the user's web usage information.

In addition, the first and second image tags are applied to be simultaneously driven to the corresponding web page of the web site to be tracked (S220). Application of the first and second image tags may be made through a service providing server 40 operating a corresponding web site.

Therefore, when the user calls the web site, the first and second image tags inserted into the web page are simultaneously driven to access the service providing server 30 and the data management server 40. In the service providing server 30 and the data management server 40, a web access history of the user is recorded in a log.

Accordingly, the ID matching server 50 logs information for a predetermined period of time after the application of the first and second image tags from one or more service providing servers 30 corresponding to the first party (hereinafter, referred to as first log information). And collect log information (hereinafter referred to as second log information) for a predetermined period after the application of the first and second image tags from the data management server 40 corresponding to the third party side (S230 and S235). ). The first and second log information are log information recorded by each server, and include a connection time for the server, user agent information connected, and an IP address of a client connected. The user agent information includes the environment information of the terminal 20 used by the connected user, such as the type and version information of the web browser used by the connected user, OS information installed in the terminal of the user. Here, when the amount of log information recorded by the server is large, it may be limited to the access log and collected.

The ID matching server 50 compares the collected first log information with the second log information, and extracts log information made by the same user in the same time zone (S240). Then, the first party cookie value and the third party cookie value of the first log information and the second log information of the same time zone are matched with the cookie values of the same user (S245).

3 is a diagram illustrating steps S240 and S245 in more detail in the method of matching non-identifiable personal information according to the present invention. First and second party cookie values and third parties of the same user are compared by referring to the first and second log information with reference thereto. The process of extracting and matching cookie values will be described in more detail.

As in the present invention, when it is desired to collect web usage information of a user accessing a specific web site through the data management server 40, another web of the same user matching the DMP cookie generated by the data management server 40 Find your site's cookie information.

Therefore, the present invention, as shown in Figure 3, is recorded in the same time zone as the access time recorded in the second log information on the basis of the second log information of the data management server 40, that is, DMP site The first log information is extracted (S305). In this case, the range of the same time zone may be within ±± αα based on the access time of the first log information in consideration of the difference in the transmission delay time on the communication network and the difference in the processing delay time according to the server performance.

When the first log information at the same time zone as the second log information is extracted, the user agent information recorded in the first and second log information is checked (S310). Here, the user agent information is environment information of the user side agent connected to the server, and as described above, the OS agent information includes OS type and version information, web browser type and version information, and device information.

In addition, the IP information of the user is checked from the first and second log information of the same time zone (S315).

If one or more of the checked user agent information and the user IP information match, the user who accesses the first party site and the third party, that is, the user who accesses the DMP site are determined to be the same user (S320). The first party cookie value of the first log information extracted in the time zone and the third part cookie value of the second log information, that is, the DMP cookie value are matched (S325).

4 is a message flow diagram illustrating an interlocking operation of a data management system by applying a non-identifying personal information matching technology according to the present invention.

Referring to FIG. 4, the operation of the data management system to which the non-identifying personal information matching method according to the present invention is applied will be described.

In the following embodiment, the user of the terminal 20 continuously uses the web sites provided by two service providing servers, that is, the first and second service providing servers 31 and 32, and manages data according to the present invention. It is assumed that the server 40 collects web usage information about web sites provided by the first and second service providing servers 31 and 32. In addition, for convenience of description, the website provided by the first service providing server 31 is referred to as site A, and the website provided by the second service providing server 32 is referred to as site B. FIG.

The present invention provides a web page of a site A provided by a first service providing server 31 and a second service providing server 32 to a target web site to which web usage information is to be collected for non-identifying personal information matching. The first and second image tags are applied to the web pages of the site B provided by the step S405. The step S405 may be performed through the first and second service providing servers 31 and 32. As described above, the first image tag is set to connect to the first party side to which the user intentionally connects, that is, the first and second service providing servers 31 and 32, and the second image tag is connected to the user's intention. It is set to connect to the third party side, that is, the data management server 40, rather than the other.

For example, the first image tag applied to the site A may be set to <img src = "http://SiteA.com/pixel?nid=2&uid=1234/>.

In this case, the second image tag may be set to <img src = "http://dmp.com/pixel?nid=2&uid=1234&url=http:\\Site_B.com\oixel\recopickuid=1234" />). . Where nid represents the ID of site A and id represents the cookie value of the corresponding nid.

On the other hand, when any user wants to access any web site and use information and / or services, the terminal 20 connected to the communication network 10 first drives a web browser (S410). When the domain name of the desired web site, for example, the domain name of the site A is input and called through the driven web browser, the terminal 20 provides the first service providing server 31 corresponding to the domain name. In step S415, the access request message is transmitted.

Accordingly, the first service providing server 31 transmits a predetermined web page corresponding to the request to the terminal 20 through the response message (S420). In this case, the web page includes first and second image tags. In addition, the first service providing server 31 transmits the cookie value set in relation to the user of the terminal 20 (S420).

The terminal 20 renders and displays the received web page through a web browser, and records the cookie value in a first site domain, that is, a site A domain.

In addition, the terminal 20 calls the first and second image tags inserted into the web page in the process of processing the web page, thereby making a call to the first service providing server 31 and the data management server 40. (S430, S435). In response to the connection, the first service providing server 31 and the data management server 40 record access logs of the terminal 20, respectively (S440 and S445). The first service providing server 31 and the data management server 40 may be connected at about the same time.

Subsequently, when the user of the terminal 20 instructs to move to the site B, the terminal 20 transmits a connection request message from the terminal 20 to the second service providing server 32 corresponding to the site B (S450). The second service providing server 32 transmits the specific web page of the site B and the cookie value set for the user in the site B to the terminal 20.

The terminal 20 processes and displays the received web page of the site B, and also records the cookie value of the site B in the first party domain (S460).

At this time, the first and second image tags inserted into the web page of the site B are called at about the same time, so that the terminal 20 connects to the second service providing server 32 and the data management server 40, respectively (S465, S470), the access log record is left in the second service providing server 32 and the data management server 40 (S475, S480).

Repeatedly performed according to the user's request of S420 to S480, when the terminal 20 accesses an arbitrary web page, the access log is simultaneously recorded in the first party server and the data management server 40. FIG.

In this state, the ID matching server 50 logs each of the web usage information to be collected, that is, the first and second service providing servers 31 and 32 and the data management server 40 which collects the web usage information, respectively. Collect information (S485, S495).

The log information may be collected in real time or at regular intervals.

In addition, the ID matching server 50 compares and analyzes the collected log information, extracts log information connected to the same access environment in the same time zone, and matches the first party cookie value with the third party cookie value (S490, S500).

Here, the log information of the site A and the site B becomes the first log information, and the log information of the DMP site becomes the second log information. Therefore, according to the method of FIG. 3, the log information of the site A log information / site B is compared based on the log information of the DMP site, and the access log almost identical to the access log of the DMP site is extracted, and the cookie value of the corresponding access log is extracted. To match each other. Here, the cookie value of the site A and the cookie value of the site B become the first party cookie value, and the cookie value of the DMP site becomes the third party cookie value.

The ID matching server 50 provides the matched cookie value to the data management server 40. Accordingly, the data management server 40 determines that the cookie value of Site A and the cookie value of Site B matched with the cookie value of the same DMP site as that of the same user, and thus the web usage information and site of Site A corresponding to the cookie value. The web usage information of B can be classified into web usage information of the same user, and user's continuous web usage information can be collected.

Therefore, even if the user's web browser is blocked from using the third party cookie value, the cookie value of the same user can be matched through the above-described non-identifying personal information matching process.
