Description

  The present invention relates to a system and method for managing data to be displayed on a client terminal including a server to which a client terminal is connected via a communication network.

  The Internet is composed of a huge network with a huge number of WEB sites connected by hyperlinks. On the Internet, a user can select a character or icon displayed on a WEB site and set with a hyperlink with a mouse or the like to enter a desired WEB site without entering a URL or using a search engine. You can jump directly.

  On the other hand, the number of WEB sites continues to increase, and there are many WEB sites with confusing domain names (URLs) and titles. Further, a person who establishes and operates a WEB site has devised a technique such as embedding a large number of keywords that are highly likely to be searched by a search engine in order to increase the number of accesses. Therefore, in many cases, the user cannot determine whether or not the WEB site searched using the search engine is really desired without actually displaying the page. As a result, the user cannot reach the desired WEB site unless the user repeatedly opens, confirms and closes many WEB sites.

  In addition, by exploiting the fact that a WEB site can be easily browsed simply by clicking on a character or the like with a hyperlink, a usage fee is charged just by clicking on a specific character or the like to display the WEB site. Internet crimes such as “one-click scams” and “phishing scams” that steal important personal information such as credit card numbers using WEB sites that are very similar to well-known WEB sites and WEB sites such as financial institutions are social issues It has become to.

  In order to solve such a problem, for example, it is conceivable to capture and save a capture of a WEB page and display a capture of the corresponding WEB page when an instruction is given from a user (client terminal).

  However, the latest WEB site updated daily cannot be displayed only by displaying the capture of the WEB site acquired in advance and stored in the database or the like.

  In addition, since there are an infinite number of WEB sites, it is unrealistic to acquire and store captures in advance, resulting in a huge amount of data and excessive pressure on storage areas such as a WEB server. .

  The present invention has been made to solve such a problem, and provides a system and method capable of displaying the latest WEB site in real time on the client terminal without accessing the WEB page on the client terminal. The purpose is to do.

  In order to achieve the above object, the present invention is a system that includes a server to which a client terminal is connected via a communication network, and manages data to be displayed on the client terminal, the first being displayed on the client terminal. Characterized in that it comprises means for acquiring a part or all of a captured image of a second WEB page in which a hyperlink is set on the WEB page, and means for outputting the acquired captured image to a client terminal. To do.

  According to the present invention, by setting CGI and a script program such as Java (registered trademark) on a server provided on the network, the character string of the first WEB page displayed on the client terminal is set. The contents of the page of the second WEB site to which the link is set are acquired as a captured image. Therefore, the content of the page can be displayed as a thumbnail image in real time on the client terminal without jumping to the linked page. Thus, the user can check the linked web page without jumping to the hyperlink destination, which is useful as a security measure such as one-click fraud and phishing.

  Specifically, when the user moves the mouse pointer to a character or the like displayed on the WEB page and set with a hyperlink, a screen shot of the hyperlink destination WEB page is acquired and displayed on the user's communication terminal. I made it.

  Further, when a command from the user is received, the server acquires a screen shot of the linked second WEB page in real time, and the information on the WEB page is stored as a cache on the server. By transferring the URL of the second WEB page to the client terminal and displaying it on the browser, the latest WEB page can be displayed in real time. Further, it is possible to display the contents of the WEB page in a shorter time than when the browser of the client terminal receives the HTML file or the like and displays the WEB page.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an overall configuration according to an embodiment of the present invention. The data management system denoted by reference numeral 1 in this figure includes a relay server 3 and a first WEB server 5 to which a client PC (terminal) 2 is connected via a public line network such as the Internet. The relay server 3 includes a cache folder 6 that stores thumbnail images of the second WEB page. The first WEB server 5 includes a WEB browser for connecting to the second WEB server. Note that the relay server 3 and the first WEB server 5 are merely functionally classified and expressed, and may be configured by a single computer system having these functions.

  In the cache folder 6, image acquisition means (program written in a script language in an HTML file: script program such as Java (registered trademark) Script) calls a CGI (Common Gateway Interface) set in the relay server 3. The acquired thumbnail image of the second WEB page is stored together with the URL. Here, the images stored in the cache folder 6 are preferably thumbnail images in which web pages are displayed as a list in a small size. The thumbnails can be generated using functions that have been put into practical use by general-purpose image editing software or the like.

Hereinafter, the processing steps of this embodiment will be described with reference to FIG.
First, when the user operates the client PC 2 and moves the mouse cursor to a specific character string or image set with a hyperlink on the first WEB page displayed by the browser (S1), the mouse cursor The Java (registered trademark) Script set for the link that monitors the operation of the server calls the CGI of the relay server 3 (S2).

  The called CGI searches the cache folder 6 based on the URL of the second WEB page that is the link destination, and checks whether the captured image of this WEB page is stored (S3). If the image is stored, the URL of the image is transferred to the client terminal 2 (S4). The browser of the client terminal 2 displays the captured image as a thumbnail based on the received URL (S5). Thus, the user can check the linked WEB page without jumping to the hyperlink destination.

  On the other hand, if it is confirmed in S3 that no image is stored in the cache folder 6, the CGI activates the browser of the first WEB server 5 and the WEB page of the second WEB server that is the link destination. The page is opened according to the URL (step S6). Further, the browser of the WEB server 5 acquires a screen shot of the second WEB page (S7), and stores the image together with the URL in the cache folder 6 (S8).

  Then, the first WEB server 5 transfers the URL of the thumbnail image stored in the cache folder 6 to the browser of the client PC 2 (S9). The browser of the client PC 2 displays a thumbnail image based on the acquired URL. Thereby, the latest WEB page can be displayed in real time.

  In addition, this invention is not limited to said embodiment, A various deformation | transformation is possible in the range which does not change the summary of invention.

FIG. 1 is a diagram showing an overall configuration according to an embodiment of the present invention.
