3 is a flowchart illustrating a process of providing web site authentication information according to an exemplary embodiment of the present invention, and FIG. 4 is a flowchart illustrating a process of providing web site authentication information according to another exemplary embodiment of the present invention.

According to FIG. 3, in step 310, the terminal 10 requests the wireless communication network 30 to access a website. The terminal 10 accesses a website by using an SMS (using a URL associated with a received SMS), a method of recognizing and reading a barcode and using a URL embedded in the barcode, and using a specific server. By using the provided service (converted to the corresponding URL), a method using numbers, letters, symbols, codes, and the like may be used. In addition, all methods of connecting the terminal 10 to the web site 90 through the wireless communication network 30 may be applied in the same manner. Here, the web site access request transmitted from the terminal 10 includes information for identifying the web site 90 (or web page) to be accessed. Typically, a URL is used as identification information of a web site, and information such as numbers, codes, and letters may be used according to each access method described above, which is mapped from a specific server to a URL of the web site 90. And may be provided to the wireless communication network 30. In the following description, the terminal 10 requests a web site access using a URL as an example. In addition, text corresponding to a service (mapping to a corresponding URL) provided by a specific server according to the above-described access method will be described. Obviously, numbers, symbols, and codes can be used.

The wireless communication network 30 transmits the requested web site connection request from the terminal 10 to the gateway server 50, and the gateway server 50 receiving the received web site connection at step 320 receives the web site 90 corresponding to the website identification information. Request authentication information to the site authentication server 70. Here, the gateway server 50 should transmit the information about the web site 90 to the site authentication server 70 in order to request the authentication information of the web site 90. As the information used for this, information of the URL unit of the web site 90 in which the corresponding web page exists may be used, or information of the domain unit of the web site 90 may be used. In addition, a method using a unique key pre-assigned to the corresponding web site 90 according to another embodiment of the present invention may be used, which will be described in detail with reference to the accompanying drawings.

In the case of the information in units of URLs, the site authentication server 70 may provide authentication information in units of web pages according to the corresponding URLs, or may provide authentication information in units of websites that provide web pages of the corresponding URLs. have. In the case of providing authentication information in units of web pages, there is an advantage that higher reliability can be provided according to authentication information for each web page, but a plurality of web pages can be provided by one website 90. Therefore, since there is a disadvantage that a lot of authentication information is used and managed, it is desirable to provide authentication information on a domain basis, that is, on a web site basis. Therefore, hereinafter, it will be described as an example of providing authentication information in units of web sites, and it will be obvious that the authentication information is provided in units of URLs, that is, in units of web pages.

In step 330, the site authentication server 70 retrieves authentication information of the corresponding web site 90 using the information of the web site 90 received from the gateway server 50, and converts the authentication information retrieved in step 340 into the gateway. Send to server 50. Of course, if the authentication information is not retrieved, it can be sent to the gateway server 50 for this.

In steps 350 to 360, the gateway server 50 requests and receives a web page (response page) according to the URL received from the terminal 10 to the corresponding website 90. Here, the gateway server 50 deletes the web page received from the web site 90 if the authentication information of the web site 90 (or web page) is included. That is, by deleting the authentication information issued by the web site 90 itself rather than the trusted authentication information, it is possible to provide reliable authentication information. Accordingly, the gateway server 50 removes the authentication information header in the web page and provides the authentication information provided from the site authentication server 70 together with the web page.

Here, the steps 320 to 340 and the steps 350 to 360 may be reversed. In other words, the web page may be acquired first from the web site 90, and then the authentication information of the web site may be obtained from the site authentication server 70. Alternatively, the authentication information request and the web page request may be simultaneously performed.

The gateway server 50 adds the authentication information received from the site authentication server 70 to the web page received from the web site 90 in step 370 and provides it to the terminal 10 in step 380. Here, the authentication information may be provided before the web page is provided as a method of providing the authentication information, or the web page may be provided together with the authentication information. When providing a web page after providing authentication information, the web page may be provided or disconnected according to a separate input of the user who confirmed the authentication information. That is, a web page may be provided according to a selection of a user who has confirmed the authentication information.

In addition, when providing a web page with the authentication information, the authentication information may be included in a separate space of the web page, so that the authentication information is output in a separate space of the web page, that is, a separate space of the terminal 10. You may. An embodiment thereof will be described below with reference to the accompanying drawings.

In addition, when the gateway server 70 is informed from the site authentication server 70 that there is no authentication information in step 340 described above, only the web page received from the web site 90 is provided to the terminal 10. In another embodiment, the terminal 10 may provide the terminal 10 with information about the absence of authentication information, and may provide a corresponding web page according to the selection of the terminal. That is, when the gateway server 50 receives a request for canceling access to the web site 90 from the terminal 10 that has received the information about the absence of authentication information, steps 350 to 380 are not performed.

Hereinafter, referring to FIG. 4, when the gateway server 50 requests authentication information of the website 90 to the site authentication server 70, authentication information when the unique key is used as identification information of the website 90. The provision process will be described.

According to FIG. 4, in step 410, the site authentication server 70 receives a request for a service according to the provision of authentication information from the web site 90. That is, the web site 90 provides the site authentication server 70 with authentication information issued from an authentication information issuing authority such as a public organization for authentication of its own site. Of course, this can be done offline.

In operation 420, the site authentication server 70 issues a unique key to the web site 90, and stores the issued unique key to correspond to the authentication information received from the web site 90.

In step 430, the gateway server 50 that receives the web site access request from the terminal 10 requests the web page to the corresponding web site 90 in step 440.

In operation 450, the web site 90 extracts the web page and transmits the web page to the gateway server 50 together with the unique key previously issued. In operation 460, the gateway server 50 requests authentication information of the web site 90 from the site authentication server 70 using the unique key. Here, only the unique key may be used as the website identification information, but the unique key may be used as an auxiliary means. That is, the URL may be used as the first web site identification information and the unique key may be used as the second web site identification information to increase the reliability thereof. Therefore, the site authentication server 70 may extract authentication information of the corresponding web site by using the first and second web site identification information.

In operation 470, the site authentication server 70 retrieves and extracts authentication information corresponding to the unique key received from the gateway server 50, and transmits the authentication information to the gateway server 50 in operation 480. In operation 490, the gateway server 50 provides the corresponding web page and authentication information to the terminal 10. Therefore, a method of providing citation information that can maintain reliability even when an arbitrary server duplicates and uses a URL by using the unique key of the present embodiment as described above can be provided.

Here, in another embodiment different from the present embodiment, the gateway server 50 does not receive the unique key from the web site 90 to obtain authentication information, but the web site 90 directly controls the site authentication server 70. The site authentication server 70 may transmit the unique key to the gateway server 50. That is, as the gateway server 50 requests a web page to the web site 90, the gateway server 50 receives the web page from the web site 90, and authenticates the web site 90 from the site authentication server 70. Receive Therefore, the load on the server in acquiring the authentication information of each web site can be eliminated so as to correspond to the connection requests from the plurality of terminals 10.
