The present invention relates to a method for providing user-specific information at the Internet service provider and a computer-readable recording medium recording a program for realizing the same. More specifically, the present invention analyzes a request for providing HTTP information from a user terminal to an information providing server. A method for providing user-specific information on the Internet service provider that adds user-specific information to the Internet service provider that provides wired and wireless Internet access service between the user terminal and the information providing server without changing the configuration of the terminal or the information providing server, and realizes the same. The present invention relates to a computer-readable recording medium having a program recorded thereon.

Information transmission between the user terminal and the information providing server on the Internet, in particular, the advertisement information is mainly composed of a banner advertisement added to a web page provided in a portal site or a keyword advertisement provided through a search engine. Alternatively, after downloading and installing a dedicated program for displaying information desired by a user including advertisement information on the user terminal side, the desired information is periodically downloaded from the information providing server and displayed on the user terminal.

1 is a diagram illustrating information provision using a wired and wireless network according to the prior art.

As shown, wired / wireless communication is performed between the user terminal 100 and the information providing server 200 to transmit and receive information, and an Internet service provider (ISP) 300 may use the user terminal 100 and the information providing server ( Perform wired and wireless internet access between 200).

The user terminal 100 is, for example, a device such as a PC or a notebook or a PDA or a mobile communication terminal. For example, the user terminal 100 transmits an information providing request such as an HTTP information providing request to the information providing server 200 to transmit the HTTP information from the information providing server 200. Receives information corresponding to the request for provision and provides it to the user.

The information providing server 200 stores various information and extracts information corresponding to the information providing request from the user terminal 100 and transmits the information to the user terminal 100. The information provided to the user terminal 100 may be formed of, for example, an HTML page generated in response to a request for providing HTTP information. Or other media files, but also preferably HTML pages.

In particular, in the case of providing advertisement information, the information providing server 200 may be, for example, a portal site or a keyword advertisement search site. Keyword ad search sites and portal sites, for example, provide search results and a list of advertiser sites corresponding to those keywords in response to a keyword that an individual has requested. When a user clicks on one of the advertiser's site lists, Provide keyword advertising that charges.

In addition, the portal site may post banner advertisements on a specific location of its start page or main page, or a page requested by an advertiser. In the case of a portal site, a user-specific advertisement, that is, a target advertisement, may be performed based on the user's profile and behavior in the site. For example, it analyzes the contents of the blog site created by the user, extracts the advertisement suitable for the content, and posts it on the user's blog site.

The ISP 300 is a device for mediating communication between the user terminal 100 and the information providing server 200. For example, a switch, a hub, a router, or a subscriber management system for performing such mediation, the packet analysis is performed. System, and the like. ISP 300 may, for example, mediate a wired Internet connection or a wireless Internet connection. However, the ISP 300 merely plays a role of mediating communication, and the ISP 300 does not provide the user-specific information to the user terminal 100. Therefore, the revenue for the provision of advertisement information or other user-specific information is attributed to the information providing server 200. Alternatively, if the ISP 300 has installed a dedicated program in the user terminal 100, the information may be provided to the user terminal 100 by using the dedicated program, but such matters may include installing the program in the user terminal 100. The disadvantage is that it is not efficient because of the cumbersome work.

Therefore, the ISP 300 can provide the user with specialized information without installing a separate program or changing the configuration of the user terminal 100, thereby generating additional profits and at the same time, the information for the public interest on the ISP 300 side. There is a growing need to provide a passage through which the user terminal 100 can be transmitted.

Hereinafter, a method for providing user-specific information of the present invention and a computer-readable recording medium recording a program for realizing the same will be described in more detail with reference to the accompanying drawings.

2 is an exemplary flowchart of a method for providing user-specific information at the Internet service provider side according to the present invention.

The present invention provides a method for providing user-specific information at an Internet Service Provider (ISP) that provides a wired / wireless Internet access service between a user terminal and an information providing server. The user-specific information is provided in a separate frame form based on subscriber information held by an ISP. How to provide.

First, the ISP side generates in advance a list of sites which are not suitable for providing user-specific information on the Internet service provider side according to the present invention (S110). That is, the present invention is characterized in that it provides information specialized to the user in the form of a frame on a web browser of the user terminal. However, some sites are not suitable for providing user-specific information in the form of frames. Therefore, the list is generated in advance for these sites, and then it is determined to determine whether the connection request from the user terminal corresponds to these sites.

The generation of such a list is performed by referring to the following cases.

For example, a specific site may provide information using a top frame of a web browser of a user terminal.

In the method of providing user-specific information on the Internet service provider side according to the present invention, it may be configured to use the highest frame of the web browser. In this case, if the same top-level frame is also used at a specific site, the possibility of an error in frame division, etc. increases. Therefore, it is preferable that a site using the highest frame does not apply the method for providing user-specific information on the Internet service provider side according to the present invention, and therefore, these sites are suitable for providing user-specific information on the Internet service provider side according to the present invention. It is classified as a site that you do not have and is registered in the list.

In addition, even if a specific site is a server that performs banking transactions, financial transactions such as securities transactions or insurance, it is classified as a site that is not suitable for providing user-specific information on the Internet service provider side according to the present invention and registered in the list.

That is, such financial transaction sites require a high level of security, and therefore, security problems may occur when an Internet service provider provides user-specific information. Therefore, these sites also provide user-specific information on an Internet service provider side according to the present invention. It is classified as a site that is not suitable for and is registered in the list.

In addition, when a specific site is a server that provides information using an encryption standard, such sites are not suitable for providing user-specific information on the Internet service provider side according to the present invention because there is a high possibility of an error in the division of a web browser on a user terminal. It is classified as a site and registered in the list.

In addition, even a site once registered in the list may be changed to be suitable for providing user-specific information on the Internet service provider side according to a change in the provided information or a change in the provided format.

Therefore, even if a site is registered on the list, it is possible to periodically check whether a frame suitable for providing user-specific information can be provided at the Internet service provider side according to the present invention at intervals of one day, one week, or one month. If possible, it can be configured to delete from the list generated in step S110.

Such periodic confirmation can be implemented, for example, by performing communication between a server on the Internet service provider side and a site registered on the list automatically in the form of a robot.

In addition, even if the site is not registered in the list, it may be changed so that it is not suitable for providing user-specific information on the Internet service provider side according to the change of the provided information or the change of the provided format.

Therefore, even if the site is not registered on the list, it is possible to check whether it is possible to generate a frame suitable for providing user-specific information at the Internet service provider side according to the present invention periodically, for example, at 1 day, 1 week, or 1 month interval. If this generation is impossible, it can be configured to register in the list generated in step S110.

Such periodic confirmation can be implemented, for example, by performing communication between a server on the Internet service provider side and a site registered on the list automatically in the form of a robot.

Thereafter, an HTTP information provision request is received from the user terminal to the information provision server (S120).

Thereafter, it is determined whether the information providing server extracted from the HTTP information providing request in step S120 corresponds to the list generated in step S110 (S130).

Step S120 or step S130 may be implemented in the following format.

The request for providing HTTP information is a request transmitted from a conventional user terminal to an information providing server, and the Internet service provider merely performs a relay between the user terminal and the information providing server.

For example, an HTTP information request can be sent by a user directly from a web browser in the user's terminal, directly through the URL of the information providing server, selected through a bookmark provided by the web browser, or sent to another website from among the contents of the currently displayed website. It is generated in response to a request for a visit to another website through a method of selecting (clicking) a moving link. That is, at the physical level, the request is transmitted from the user terminal to the information providing server in the form of an HTTP information providing request packet.

The HTTP information provision request packet includes a header and a payload, cookie information corresponding to a web site or a corresponding resource, cookie information corresponding to a web site, referrer information, an IP address of a user terminal, an IP address of an information providing server, and the like. It includes. In this case, it may include not only an HTML page but also a request for providing an image resource or an audio / video resource for displaying the HTML page. Most requests for image resources and other resources occur in the process of re-requesting other resources needed to complete the page within the HTML document.

In the method for providing user-specific information at the Internet service provider according to the present invention, the request for providing HTTP information may be analyzed and provided in the form of user-specific information in various forms.

In particular, after the HTTP information providing request is copied in a mirroring manner, the HTTP information providing request can be analyzed.

The mirroring is described in more detail as follows.

Early network equipment used dummy hubs to deliver information in a manner that broadcasts all packets. That is, for example, when the network card of the PC terminal is described, if the packet corresponding to its own address among the packets broadcast from the dummy hub is received, the non-corresponding packet passes through the communication.

In this case, when the network card is set to promiscuous mode, all packets are accepted, and when these packets are analyzed, various statistical information about the traffic being transmitted on the network can be checked.

However, as the dummy hub increases the packet traffic, the network is overloaded, so it is not used unless it is a special case, and thus the switch is popularized.

In other words, the switch has the advantage of transmitting the packet accurately to the destination port. However, since there is no way to see all the network packets in terms of analyzing packet information transmitted and received through the network, most switches use a mirroring method. to provide.

When the mirroring mode of the switch is set, all packets are copied and delivered to the mirroring port one by one. Unlike the firewall or the proxy, the packet mirroring method does not adopt a gateway method, and thus, does not cause a network failure or a one-stop failure, and has a large capacity.

If the mirroring mode of the switch is selected in this way, the load of the switch may be generated, and thus the same effect as setting the mirroring mode may be obtained by arranging tap equipment dedicated to copying packets in the middle of the switch.

In the present invention, by copying the request for providing HTTP information from the user terminal to the information providing server by using the above-described mirroring method and analyzing the same, the HTTP information providing request can be implemented while reducing the load on the network.

That is, in step S120, upon receiving the request for providing the HTTP information, it is copied in a mirroring manner.

Subsequently, in step S130, the information about the information providing server is extracted from the HTTP information providing request copied in the mirroring method in step S120, and it is determined whether this corresponds to the list generated in step S110.

Subsequently, when the determination result information providing server of step S130 does not correspond to the list, it analyzes the HTTP information providing request received in step S120 and configures user-specific information to be transmitted to the user terminal (S140).

That is, the user-specific information is configured by analyzing the above-described HTTP information provision request packet. The step S140 will be described in more detail as follows.

First, the analysis of the HTTP information provision request may analyze the HTTP information provision request only when the user of the user terminal is identified as a predetermined user as being provided with the user-specific information. In other words, the user-specific information can be provided only to the user who has contracted with the Internet service provider, rather than being performed for all users, and this can be configured to provide the user terminal information or the user ID. It is possible to check on the basis of identification information.

In the analysis of the request for providing HTTP information, first determine whether there is a request for providing HTTP information for the same HTML page from the user terminal within a predetermined time for the HTML page corresponding to the request for providing the HTTP information, and then It can also be configured to resolve HTTP information provision requests only if no HTTP information provision requests have been made.

That is, when the user-specific information is provided for all the HTTP information provision requests of the user, the user-specific information may be provided after the predetermined time elapses or the predetermined number of times since the user-specific information may be repeatedly provided.

In particular, in this case, whether the request for providing HTTP information for the same HTML page has been made may be based on referrer information in the request for providing HTTP information, or after storing the request for providing HTTP information from the user's terminal in advance, You can also determine if there was a request to provide HTTP information for the same HTML page within the time.

Determination of whether there has been a request for providing HTTP information on the same HTML page based on the reference information will be described later.

User-specific information is for public purposes, such as finding a lost child, finding an elderly dementia, or obtaining rare blood, or promptly delivering the information to a user due to a flood, fire, dust, pollution, terrorism, war, or natural disaster. It may be emergency information that should be performed, or may be information such as advertisement information based on information of a user or advertisement information based on a region where a user terminal is located.

The configuration of user-specific information can use the following method.

First, the user specific information may be configured based on the network address of the user terminal or the user specific information may be configured based on the user information of the user terminal.

That is, the Internet service provider (ISP) generally performs terminal authentication or user authentication and then performs an Internet access service of the user terminal.

Such terminal authentication may be performed by confirming the MAC address of a component used for network connection of a user card, such as a network card, also referred to as MAC authentication. Such terminal authentication is preferably a personal computer or may be performed in the case of a PDA, a mobile terminal or even a software robot. The ISP may configure user-specific information based on a network address identified through terminal authentication. In other words, the ISP constructs and uses a database linking the terminal's IP address history with the region. When interworking with such a data base, the ISP knows which region the user terminal sends the request for providing HTTP information. It is possible to organize information specialized for.

User authentication is generally performed through a user ID and password, but may be performed through other authentication means. Since the ISP stores information on the subscribed user, the user-specific information can be configured based on the user's information identified through user authentication. For example, the user-specific information may be configured based on the user's age, gender, and preference information.

Alternatively, the user specific information may be configured based on the product information related to the user terminal. For example, when receiving information on the web browser of the user terminal, the user-specific information may be converted into a form suitable for the web browser of the user terminal and configured.

Alternatively, the user specific information may be configured according to a predetermined user specific information configuration condition.

In this case, the user-specific information configuration condition may configure the user-specific information according to, for example, the user-specific information according to the number of times of receiving the HTTP information provision request from the ISP side or the time of receiving the HTTP information provision request. In other words, instead of providing user-specific information for every connection, if the user sets the conditions for providing user-specific information in advance such as once every five times or once every predetermined time, the user-specific information is configured accordingly.

Subsequently, in response to the HTTP information provision request, a response including the HTTP information provision request and the user-specific information to be displayed in a frame form on the web browser of the user terminal is transmitted to the user terminal (S150).

In this case, after generating the user-specific information additional information including the display type of the user-specific information configured in step S140 or the update period of the user-specific information, the user-specific information additional information may be transmitted together with the response.

In addition, a fake packet having a FIN flag set may be transmitted to a user terminal for a request for providing HTTP information.

In this case, the information providing server may transmit a pseudo packet in which the RESET or FIN flag is set to the information providing server. Such RESET or FIN flag imitation packet transmission to the information providing server may be used to specifically prevent a session connection between the user terminal and the information providing server in response to the HTTP information providing request transmitted to the information providing server at step S120. have.

The transmission of the RESET or FIN flag will be described in more detail as follows.

A TCP session may be established between the user terminal and the information provision server in response to the HTTP information provision request. Although the ISP sends a response to the user terminal in response to the HTTP information provision request received in step S120 through step S150, the session connection between the user terminal and the information provision server is meaningless, in order to reliably block such session connection. The following configuration can be taken.

In other words, fake packets are used to block TCP sessions.

A pseudo packet is a packet whose IP header, FIN or RESET flag is set in the packet header part sent to the user terminal or the packet header part sent to the information providing server. By constructing and transmitting the content, it blocks or bypasses the session connection between the user terminal and the information providing server intended for the original session connection.

In this case, when the web browser of the user terminal receives the dummy packet having the FIN flag set, the HTTP information provision request transmitted in step S120 is regarded as the end of the data transmission normally, and the contents in the payload portion of the dummy packet are received. Configure pages to display.

In addition, the information providing server terminates the session for the HTTP information providing request when receiving the dummy packet with the FIN or RESET flag set.

In addition, the response may be configured to display information on the display of the information corresponding to the HTTP information provision request and the display of the user-specific information, such as frame information, in the user terminal.

That is, in the method for providing user-specific information at the Internet service provider according to the present invention, the user-specific information and the information provided in the form of a web page from the information providing server can be simultaneously displayed on the user terminal through a frame structure.

"Frames" are the partitioning of a web page into sections, and generally do not use many frames.

Such a frame may be arranged at the top, bottom, left and right sides of the web browser screen, and may be configured such that the frame division is clearly displayed or transparent so as not to be distinguished in appearance.

Using this frame structure, a number of HTML documents can be displayed in a web browser, and can be displayed in a separate window or subwindows. The windows of such a frame may include a configuration such as scrolling. For example, in the same window, one frame may be configured as a fixed advertising banner, the second frame may display a navigation menu, and the third frame may display main information in a scroll form or display information according to the navigation menu. can do.

In the method of providing user-specific information at the Internet service provider side according to the present invention, the user-specific information provided by the ISP side at the same time as the information provided from the information providing server through the HTTP information provision request from the user terminal using such a frame structure is inconvenient for the user. It can be configured to be displayed through the frame without, in this case, it may be configured so that the user does not feel that the frame is set, preferably using a transparent structure frame.

In this case, the response transmitted to the user terminal is based on logic for checking whether a web browser frame generated corresponding to the user-specific information of step S140 already exists in the web browser processing the HTTP information provision request from the user terminal, and the user-specific information. If there is no corresponding web browser frame generated, logic for dividing the frame of the web browser into two, one of the divided frames displays user-specific information, and the other frame provides information on the HTTP information provision request of step S120. It can include logic to request an HTTP resource from a provisioning server.

In addition, the response may further include logic to indicate that the request for the second HTTP request for the same HTTP resource from the user terminal to the information providing server when the HTTP resource request. This second outgoing request may be included in the HTTP referrer, for example.

Subsequently, in response to the response transmitted through step S150, the HTTP information providing request retransmitted from the user terminal to the information providing server is relayed to the information providing server (S160).

That is, in this step, although the HTTP information provision request in step S120 is bypassed through the response transmission in step S150 to provide additional user-specific information, the user needs to display the desired information so that the HTTP information provision request can be transmitted again. To construct.

Thereafter, in response to the HTTP information providing request retransmitted through step S160, the information provided from the information providing server is relayed to the user terminal (S170).

In this case, the ISP transmits the information to the user terminal without including any additional information. In other words, since the user-specific information transmitted from the ISP is already transmitted to the user terminal, it is not necessary to retransmit the user-specific information again. If it is transmitted again, excessive user-specific information is displayed on the user terminal side, and the request for providing HTTP information is again performed. This is because a lot of time delay occurs until the user displays the desired information.

The present invention also provides a computer-readable recording medium having recorded thereon a program for realizing each step of the method for providing user-specific information at the Internet service provider side according to the present invention.

However, since the description of the recording medium according to the present invention overlaps with the description of the method for providing user-specific information at the Internet service provider side according to the present invention with reference to FIG. 2, a detailed description thereof will be omitted.

Although the configuration of the present invention has been described in detail, it is only for illustrating the present invention. For example, the list generated in step S110 includes information of sites that are not suitable for providing user-specific information, but may be modified to include information of sites suitable for providing user-specific information. That is, a list capable of providing user-specific information by an explicit contract between a specific site and an Internet service provider may be generated, and the following steps may be performed based on the list.

Therefore, the protection scope of the present invention is not limited by the above-described embodiments, the protection scope of the present invention is defined through the description of the claims to be described later.

As described above, according to the present invention, the Internet provides a wired / wireless internet access service between the user terminal and the information providing server without changing the configuration of the user terminal or the information providing server by analyzing the HTTP information providing request from the user terminal to the information providing server. The service provider may add and provide information specialized for the user.
