JP5809097B2 - Web browsing history acquisition system - Google Patents

Description

  The present invention relates to a web browsing history acquisition system that acquires a browsing history related to a web page browsed by a user with a web browser.

Techniques for acquiring and storing an operation history on a user terminal as well as a web page browsing history have been proposed (see, for example, Patent Document 1 and Non-Patent Document 1).

  Further, as a method of acquiring history information browsed by a user with a web browser, there is a method of acquiring information regarding all web pages browsed by the user.

  For example, in “History”, which is a function of Internet Explorer (registered trademark) provided by Microsoft, which is a typical web browser, the last display date, URL, title, Get and save etc.

  On the other hand, there is a method using a proxy server as a method of acquiring history information of a web page browsed by a web browser (see, for example, Patent Document 2). The proxy server is a relay device used when a web browser acquires a web page on the network, and can record the accessed browser type, the accessed user, the URL of the viewed web page, the access date and time, etc. in the proxy server. .

  Saving a browsing history of a web page browsed by a user is useful for various purposes, such as being able to use a past browsing history as a tool for supporting memories.

  However, if all the information that can be acquired is stored in order to make it easier to remember, not only the amount of stored data becomes enormous, but also the processing amount for acquiring and storing the information increases.

  In the tool described in Non-Patent Document 1, not only the browsing date, URL, and title acquired by the history function of a general web browser, but also the operation history of the mouse and keyboard on the web page and the HTML source code of the page Detailed history information such as a captured image of the browsing screen can be saved.

  Saving this information means that each time a user browses a web page, the save process is performed, so the web browser being viewed becomes heavier and saved every time the web page to be browsed changes. Data will continue to increase, which will put pressure on storage memory such as the hard disk of the terminal.

  In particular, recent portable devices such as smart phones have low specifications such as computing power and storage capacity compared to personal computers, and it has been difficult to acquire detailed history information.

  On the other hand, if various information of the browsing history stored in the user terminal is stored in the proxy server using the proxy server, the processing load on the user terminal can be reduced.

  However, the proxy server may not be able to save the browsing history depending on the web page to be browsed. For example, when browsing an encrypted web page such as SSL (Secure Socket Layer) communication, the proxy server can obtain the URL of the accessed web page, but the web page title and HTML source code can be obtained. The content of the web page such as the captured image of the browsing screen cannot be acquired.

  In addition, when accessing the web page held in the user terminal as the browsing history information of the web browser, the user accesses the “cache”, and even if the user browses the web page on the user terminal, Since the proxy server is not routed, the browsing history cannot be saved on the proxy server.

  In addition, if you launch multiple web browsers and browse multiple web pages in parallel, or browse multiple tabs in parallel using the tab function of the web browser, the proxy server will display those windows. There is a problem that it is impossible to reconstruct the browsing web page in chronological order because it cannot know the switching of tabs.

  The present invention has been made in view of the above circumstances, and even when the user terminal is low-spec, the browsing history is shown more than the conventional method so that the browsing history regarding the web page can be smoothly acquired at the user terminal. An object of the present invention is to provide a web browsing history acquisition system capable of reducing the processing amount for storing browsing data and reducing the storage data amount.

To achieve the above object, the web browsing history acquisition system of the present invention is configured to determine whether or not a web page is accessed via a proxy server when the web page is displayed by a web browser , and the proxy server. Communication determining means for determining whether or not browsing data indicating a browsing history related to the web page can be acquired by the proxy server based on at least one of communication protocols when accessing the web page via the network; and the communication When it is determined by the determination means that the browsing data cannot be acquired by the proxy server, the terminal / browsing data acquisition means for acquiring the browsing data and the browsing data acquired by the terminal / browsing data acquisition means A data transmission means for transmitting to the proxy server at a predetermined timing, Including storage control means for obtaining the browsing data related to the web page displayed on the web browser via its own device and the browsing data transmitted from the data transmission means, and controlling to acquire and store the browsing data in the storage means And the proxy server.

According to the web browsing history acquisition system of the present invention, in the user terminal, when the communication determination means is displaying the web page with the web browser, whether or not the web page is accessed via the proxy server , Based on at least one of the communication protocols when accessing the web page via the proxy server, it is determined whether or not the proxy server can acquire the browsing data indicating the browsing history related to the web page. When the terminal / browsing data acquisition unit determines that the browsing data cannot be acquired by the proxy server by the communication determination unit, the browsing data is acquired, and the data transmission unit is acquired by the terminal / browsing data acquisition unit. The browse data is transmitted to the proxy server at a predetermined timing. On the other hand, in the proxy server, the storage control unit is controlled to acquire the browsing data related to the web page displayed on the web browser via its own device and the browsing data transmitted from the data transmission unit, and store them in the storage unit. To do.

  In this way, when the browsing data cannot be acquired by the proxy server, the browsing data is acquired by the user terminal and transmitted to the proxy server. Therefore, even when the user terminal is low-spec, In order to smoothly acquire the browsing history related to the web page, it is possible to reduce the processing amount for storing browsing data indicating the browsing history, and to reduce the storage data amount, as compared with the conventional method.

  In addition, the communication determination unit can determine that the browsing data cannot be acquired by the proxy server when communication with the proxy server is encrypted communication.

  Further, the communication determination means can determine that the browsing data cannot be acquired by the proxy server when the web page is displayed using a cache without communicating with the proxy server. .

  In the web browsing history acquisition device of the present invention, the user terminal device acquires the browsing data related to the terminal stored in the storage unit of the proxy server and displays the browsing information indicated by the browsing data. Management means for receiving the operation related to the obtained browsing data as well as displaying on the means can be configured.

  As described above, according to the web browsing history acquisition system of the present invention, when browsing data cannot be acquired by the proxy server, the browsing data is acquired by the user terminal and transmitted to the proxy server. Even if the user terminal is low-spec, the processing amount for saving the browsing data indicating the browsing history is reduced compared to the conventional method so that the browsing history regarding the web page can be smoothly acquired in the user terminal, and the stored data The effect that the amount can be reduced is obtained.

The server / browsing data acquisition unit 21 and the data reception unit 22 are examples of the storage control unit of the present invention.

  The authentication unit 13 performs a procedure for performing authentication when accessing the proxy server 12 from the user terminal 11. For example, a user ID and password are registered in advance in the proxy server 12, and when accessing the proxy server 12, the user ID and password input by the user are received and transmitted to the proxy server 12.

  The communication determination unit 14 determines whether or not browsing data can be acquired by the proxy server 12. Specifically, it monitors the communication status on the network when the web page displayed on the web browser becomes active, determines whether the communication protocol is SSL, and browses the web page Whether or not is a cache. If the web page being browsed is an SSL page or is a cache, it is determined that browsing data cannot be acquired by the proxy server 12.

  When the communication determining unit 14 determines that the browsing data cannot be acquired by the communication determining unit 14, the terminal / browsing data acquiring unit 15 is information about the web page being browsed by the web browser, for example, the browsing date and time, the URL of the web page And a title are acquired as browsing data indicating a browsing history. The acquired browsing data is stored in the terminal / browsing data storage unit 18.

  The data transmission unit 16 transmits the browsing data stored in the terminal / browsing data storage unit 18 to the proxy server 12 at a predetermined timing.

  The browsing history viewer unit 17 acquires the browsing data in the user terminal 11 held in the proxy server 12, and displays the browsing history indicated by the acquired browsing data on the web browser. Further, with respect to the acquired browsing data, an operation by the user such as deleting unnecessary browsing data is received, and operation information regarding the received browsing data is transmitted to the proxy server 12.

  The user management unit 20 performs user authentication when accessing from the user terminal 11. For example, a user ID and password pair is registered in the user information storage unit 24 in advance, and user authentication is performed by checking the user ID and password transmitted from the user terminal 11.

  The server / browsing data acquisition unit 21 acquires browsing data indicating a browsing history related to the web page being browsed via the proxy server 12 from the user terminal 11 and stores the browsing data in the server / browsing data storage unit 25.

  The data receiving unit 22 receives the browsing data transmitted from the user terminal 11 and stores it in the server / browsing data storage unit 25. Accordingly, the server / browsing data storage unit 25 stores the browsing data acquired from the proxy server 12 and the browsing data transmitted from the user terminal 11, that is, the browsing data that could not be acquired by the proxy server 12. Is done.

  In response to the inquiry from the browsing history viewer unit 17, the data management unit 23 transmits the browsing data stored in the server / browsing data storage unit 25 to the user terminal 11. Further, the operation information transmitted from the browsing history viewer unit 17 is received, and the browsing data stored in the server / browsing data storage unit 25 is updated.

  Next, the operation of the web browsing history acquisition system 10 of this embodiment will be described. When the web browser is activated in the user terminal 11, the terminal / browsing data acquisition process shown in FIG. 2 is executed in the user terminal 11, and the server / browsing data acquisition process shown in FIG. 3 is executed in the proxy server 12. Is done. When the browsing data viewer is activated in the user terminal 11, the terminal / browsing history viewer process shown in FIG. 4 is executed in the user terminal 11, and the server A browsing history viewer process is executed. Hereinafter, each process is explained in full detail.

  The terminal / browsing data acquisition process (FIG. 2) starts from the start of the web browser on the user terminal 11.

  In step 100, the authentication unit 13 transmits the user ID and password to the proxy server 12 designated in advance. If the user authentication is permitted by the proxy server 12, the process proceeds to step 102. If the user authentication fails, the terminal / browsing data acquisition process is terminated.

  In step 102, the communication determination unit 14 monitors the communication state on the network when the web page displayed on the web browser becomes active, and determines whether there is network communication. If the web browser is accessing the web page via the proxy server 12, it is determined that there is network communication, and the routine proceeds to step 104. On the other hand, when the web page browsed by the web browser is a cache, it is determined that there is no network communication, and the process proceeds to step 106.

  When it is determined that there is network communication and the process proceeds to step 104, the communication determination unit 14 determines whether or not the communication protocol is http communication. In the case of http communication, the process proceeds to step 108. In the case of not http communication, that is, in the case of https communication, it is determined that the web page being browsed is a web page encrypted by SSL, and the process proceeds to step 106. Transition.

  If the determination in step 102 or step 104 is negative, it means that the browsing data cannot be acquired in the proxy server 12, and the terminal / browsing data acquisition unit 15 is browsing with a web browser in step 106. Information relating to the web page, such as browsing date and time, URL and title of the web page, is acquired as browsing data indicating the browsing history and stored in the terminal / browsing data storage unit 18.

  If affirmative determination is made in step 102 and step 104, it is a case where browsing data can be acquired in the proxy server 12, so the user terminal 11 proceeds to step 108 without acquiring browsing data.

  In step 108, the data transmission unit 16 determines whether or not the web browser is terminated. If the web browser has not ended, the process returns to step 102, and the processes of steps 102 to 108 are repeated as long as there is a page transition. On the other hand, when the web browser is terminated, the process proceeds to step 110, where the data transmission unit 16 transmits the browsing data stored in the terminal / browsing data storage unit 18 to the proxy server 12 to acquire the terminal / browsing data. End the process.

  Next, the server / browsing data acquisition process (FIG. 3) starts with the access from the user terminal 11 as a starting point.

  In step 120, the user management unit 20 performs user authentication by comparing the user ID and password registered in the user information storage unit 24 with the user ID and password transmitted from the user terminal 11. When the user authentication is permitted, the process proceeds to step 122. When the user authentication is rejected, the fact is transmitted to the user terminal 11, and the server / browsing data acquisition process is terminated.

  In step 122, the server / browsing data acquisition unit 21 acquires browsing data indicating browsing history related to the web page browsed via the proxy server 12 from the user terminal 11, and associates the server / browsing data with the user ID. Save in the storage unit 25.

  Next, in step 124, the data receiving unit 22 determines whether or not the browsing data transmitted from the user terminal 11 has been received. If it has not been received, the process returns to step 122. Proceeds to step 126.

  In step 126, the data receiving unit 22 stores the browsing data received in step 124 in the server / browsing data storage unit 25 in association with the user ID, and ends the server / browsing data acquisition process.

  Next, the terminal / browsing viewer process (FIG. 4) starts with the browsing history viewer function being activated on the user terminal 11 as a starting point.

  In step 130, the browsing history viewer unit 17 requests the proxy server 12 to transmit the browsing data stored in the server / browsing data storage unit 25, acquires the browsing data transmitted in response to the request, The browsing history indicated by the acquired browsing data is displayed.

  Next, in step 132, the browsing history viewer unit 17 determines whether or not there has been an operation by the user such as deleting unnecessary browsing data for the acquired browsing data. In addition, as deletion of browsing data, you may delete all the browsing data acquired by the said step 130, and may delete only one part. For example, when browsing data includes the URL and browsing time of the browsing page, the thumbnail image of the browsing page, and the html file constituting the browsing page, the html file and thumbnail image are deleted, but the URL and browsing time are It may be partially deleted that it is retained without being deleted.

  If there is an operation on the browsing data, the process proceeds to step 134, the operation information is transmitted to the proxy server 12, and the process proceeds to step 136. If there is no operation on the browsing data, the process proceeds to step 136 as it is.

  In step 136, the browsing history viewer unit 17 determines whether or not the browsing history viewer function has ended. If the browsing history viewer unit 17 has not ended, the process returns to step 130 and repeats the processing in steps 130 to 136, thereby browsing the browsing history. When the viewer function is terminated, the process proceeds to step 138, the proxy server 12 is notified that the browsing history viewer function is terminated, and the terminal / viewing viewer process is terminated.

  Next, the server / browsing viewer process (FIG. 5) starts from the reception of a request for browsing data by the browsing history viewer function from the user terminal 11.

  In step 140, the data management unit 23 reads the browsing data corresponding to the user ID of the user terminal 11 in communication from the server / browsing data storage unit 25 and transmits it to the user terminal 11.

  Next, in step 142, the data management unit 23 determines whether or not the operation information transmitted from the user terminal 11 has been received. When the operation information is received, the process proceeds to step 144, and the data management unit 23 updates the browsing data stored in the server / browsing data storage unit 25 by deleting the browsing data based on the received operation information. Then, the process proceeds to step 146. If the operation information has not been received, the process proceeds to step 146 as it is.

  In step 146, it is determined whether or not the browsing history viewer function has ended by determining whether or not the browsing history viewer function 17 of the user terminal 11 has notified the end of the browsing history viewer function. If the browsing history viewer function has not ended, the process returns to step 140, and the processing of steps 140 to 146 is repeated. If the browsing history viewer function ends, the server / viewing viewer process ends.

  As described above, according to the web browsing history acquisition system of the present embodiment, when browsing data can be acquired by the proxy server, the browsing data is not acquired by the user terminal without acquiring the browsing data. If the browsing data cannot be acquired by the proxy server, the browsing history data is temporarily saved at the user terminal and sent to the proxy server at a predetermined timing. By managing it together with the acquired browsing data, even if the user terminal is low-spec, the processing amount for storing browsing data can be reduced so that the browsing history of web pages can be acquired smoothly on the user terminal This reduces the amount of browsing data saved.

  In the above embodiment, the case where the browsing data stored up to that time is transmitted to the proxy server at the end of the web browser has been described. However, the timing for transmitting the browsing data to the proxy server is limited to this. Not. It may be transmitted at predetermined time intervals while the web browser is activated, or may be transmitted at a timing when the browsing data stored in the terminal / browsing data storage unit exceeds a predetermined amount. An appropriate transmission timing may be set according to the processing amount for browsing data transmission and the storage capacity of the terminal / browsing data storage unit.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible without departing from the gist of the present invention.

  In addition, the above-mentioned web browsing history acquisition system has a computer system inside, but the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used. Shall be.

  In the present specification, the embodiment has been described in which the program is installed in advance. However, the program can be provided by being stored in a computer-readable recording medium.
