Description

  The present invention relates to an information processing apparatus and an information processing method.

  In companies and the like, a plurality of personal computers (PCs) are connected to a local area network. In general, the local area network is connected to the external Internet via a firewall or the like. Also, a PC user such as a company employee uses a Web browser, which is software installed in advance on the PC, to connect to a Web server installed outside the company via the Internet. Then, the user browses a document or image stored in the HTML format or the like on the Web server using the Web browser.

  However, it has been pointed out that problems such as a decrease in business efficiency of employees by browsing documents and images that are not directly related to work during working hours and an increase in information system costs of companies due to private network use have been pointed out.

  Therefore, by keeping records regarding the browsing of documents and images by employees, etc., these actions of employees, etc. are suppressed, and for employees who have many of these actions, the system administrator, supervisor, etc. It is expected to be careful to stop the action. There is Patent Document 1 as a prior art for realizing such a thing.

  In the technique described in Patent Document 1, communication packets flowing on a network are collected, and a web access history is databased in real time without applying a load. A method for realizing this is to extract the URL and IP address from the acquired communication packet and store them in the access record database.

JP 2004-318718 A

  However, the conventional website browsing / recording apparatus such as Patent Document 1 has the following problems. In other words, for example, if an employee etc. abcdef. co. When a web page called jp is browsed, the file name of the image file specified in the HTML source of the web page and displayed on the page is also recorded and displayed as a browsing record. Therefore, when an administrator or the like browses a website browsing record, there is a problem that the display content is complicated. In addition, there is a problem that the storage capacity of the information processing apparatus is compressed in order to store such unnecessary information.

Such an example will be described more specifically with reference to FIGS.
FIG. 1 is a diagram illustrating an example of a Web page viewed by a user. FIG. 2 is a diagram illustrating a flow from when the user (or the user's PC 21) accesses the Web server 22 to display a Web page on the Web browser of the user's PC 21. FIG. 3 is a diagram illustrating an example of a recorded history.

  Reference numeral 11 in FIG. 1 denotes a screen (Web page) in which a page text in HTML (Hyper Text Markup Language) language is displayed by a Web browser. The employee or the like inputs, for example, the URL “www.abcdef.co.jp” from the Web browser of his / her PC 21 and transmits it to the Web server (WWW) 22 (S step 23 in FIG. 2).

  As a result, the Web server 22 transmits a file “www.abcdef.co.jp/index.html” to the Web browser of the PC 21 (step S24 in FIG. 2).

  When receiving the file, the Web browser of the PC 21 detects file information of two images (12 and 13 in FIG. 1) included in the HTML source. That is, the Web browser detects “www.abcdef.co.jp/top/Japanes.gif” and “www.abcdef.co.jp/top/english.gif”. That is, the web browser requests each image file from the web server 22 (step S25 in FIG. 2).

  In response to this request, the Web server 22 transmits each image file to the Web browser of the PC 21 (step S26 in FIG. 2), and the display of the Web page 11 shown in FIG. 1 is completed.

  In this case, an example of a history recorded and displayed in the website browsing / recording apparatus is shown in FIG. As shown in this example, the user inputs the character string to the Web browser with the intention of displaying “www.abcdef.co.jp”. In spite of this, three histories are recorded (or displayed) as shown in FIG. 3 for the screen display of FIG. Of these, only 31 is significant information as the user's browsing record, and the history 32 and 33 indicating that the image file is requested are not intentionally requested by the user. There is not much sex.

  FIG. 4 shows an example of an ideal history browsing screen recorded and displayed in the website browsing recording apparatus in this example. FIG. 4 is a diagram illustrating an example of an ideal history browsing screen. In FIG. 4, only significant information 41 is displayed. On the other hand, in FIG. 3, since 32 and 33 exist, three histories are recorded (or displayed) in one user access, which is very complicated when the system administrator or the like browses. There is a problem that it is difficult to see, and a problem that the storage capacity becomes larger than necessary.

  The present invention has been made in view of such problems, and an object of the present invention is to selectively create or record a history of operations on highly important files among file operations requested by an information browsing apparatus.

  Therefore, the present invention provides a storage unit for storing file attribute information and a request for a file operation transmitted from an information browsing apparatus communicable via a network to an information providing apparatus communicable via the network. According to the determination means in the acquisition means, the determination means for determining whether the request acquired in the acquisition means is a request for a file having an attribute related to the file attribute information, and the determination result in the determination means, Control means for controlling whether or not to generate history information related to the request.

  Further, the present invention obtains a request relating to a file operation transmitted from a storage means for storing ratio information and an information browsing apparatus communicable via a network to an information providing apparatus communicable via the network. A request number counting unit that counts the number of requests related to a file operation in response to the acquisition of the request in the acquisition unit, and a file for each file attribute information in accordance with the acquisition of the request in the acquisition unit. A request count counting unit for each attribute information that counts the number of requests related to the operation; a determination unit that determines whether a ratio of the request count and the request count for each attribute information exceeds a ratio of the ratio information; Control means for controlling whether or not history information related to the request is created according to a determination result in the determination means.

  The present invention may be an information processing method, a program, and a storage medium.

  According to the present invention, it is possible to selectively create or record a history of operations on highly important files among file operations requested by the information browsing apparatus.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 6 is a diagram illustrating an example of a system configuration and a functional configuration of the information processing apparatus 52 according to the first embodiment.
In FIG. 6, reference numeral 51 denotes an information browsing apparatus, for example, a general PC. It is assumed that a web browser is installed in the information browsing apparatus 51.

  The information processing device 52 records a history of the information browsing device 51 accessing a Web page provided by the information providing device 55. The user can browse the history using the information processing apparatus 52. The information providing apparatus 55 is, for example, a Web server installed on the Internet or an intranet. That is, the information providing device 55, the information browsing device 51, and the information processing device 52 are connected to be communicable via a network.

  The information processing apparatus 52 includes a history collection setting unit 521, an excluded file extension table 522, a flag value recording unit 523, a packet acquisition unit 524, a packet analysis unit 525, a history recording unit 526, a history browsing unit 527, and the like as functional configurations. Including.

  The history collection setting unit 521 performs settings related to history collection based on information selected (or input) via a history collection setting screen shown in, for example, FIG. The excluded file extension table 522 stores history excluded file extension information based on information from the history collection setting unit 521. The flag value recording unit 523 records a flag value indicating whether or not history collection is performed based on information from the history collection setting unit 521. The history exclusion file extension information, the flag value, and the like are recorded (or stored) in the HDD 107 or the like.

  The packet acquisition unit 524 acquires a communication packet that flows on the network. The packet analysis unit 525 analyzes the communication packet acquired by the packet acquisition unit 524. Further, the packet analysis unit 525 creates a history (history information) based on the analyzed result. The history recording unit 526 records the history created by the packet analysis unit 525 in the HDD 107 or the like. The history browsing unit 527 displays a history browsing screen shown in FIG. 12, which will be described later, on the display device 105, for example, so that the user can browse the history.

  The information browsing device 51 and the information processing device 52 are connected by a LAN. The information browsing device 51 is connected to the Internet 54 via the firewall 53, and requests access to the information providing device 55 that owns the Web page that the user wants to browse in response to the user's browsing request. Thus, the user of the information browsing apparatus 51 can browse the Web page that the user wants to browse.

FIG. 8 is a flowchart illustrating an example of the flow of history collection setting processing.
In step S71, the history collection setting unit 521 does not need to record as a file browsing history even when browsing specified in the excluded file extension setting part 62 of the history collection setting screen as shown in 61 of FIG. Get the file extension of a file. FIG. 7 is a diagram illustrating an example of a history collection screen according to the first embodiment.

  Subsequently, in step S72, the history collection setting unit 521 records the file extension acquired in step S71 as an excluded file extension in the excluded file extension table 522.

  An example of an excluded file extension recorded in the excluded file extension table 522 is shown in FIG. FIG. 9 is a diagram illustrating an example of the excluded file extension table 522.

  Returning to the description of FIG. 8 again, in step S73, the history collection setting unit 521 receives a setting for starting, continuing, or interrupting history collection set by the user via a screen or the like.

  Subsequently, in step S74, the history collection setting unit 521 determines whether to start, continue, or interrupt history collection based on the setting received in step S73. If the history collection setting unit 521 determines that the history collection is to be interrupted, the history collection setting unit 521 proceeds to step S75. If the history collection setting unit 521 determines to start or continue the history collection, the history collection setting unit 521 proceeds to step S76.

  In step S75, the history collection setting unit 521 stores the flag value FALSE in the flag value recording unit 523, and ends the process illustrated in FIG.

  On the other hand, in step S76, the history collection setting unit 521 refers to the flag value recording unit 523. Subsequently, in step S77, the history collection setting unit 521 determines whether the flag value is FALSE based on the result referred to in step S76. When the history collection setting unit 521 determines that the flag value is TRUE, the history collection setting unit 521 ends the process illustrated in FIG. 8. When the history collection setting unit 521 determines that the flag value is FALSE, the process proceeds to step S78.

  In step S78, the history collection setting unit 521 transmits a history collection start request to the packet acquisition unit 524. Subsequently, in step S79, the history collection setting unit 521 stores the flag value TRUE in the flag value recording unit 523, and ends the process illustrated in FIG.

  In the case of TRUE, the flag value indicates that history collection is being performed, and in the case of FALSE, history collection is not performed. The default flag value is FALSE.

FIG. 10 is a flowchart illustrating an example of a processing flow from acquiring a communication packet to recording a history according to the first exemplary embodiment.
In step S <b> 91, the packet acquisition unit 524 receives a history collection start request from the history collection setting unit 521. Then, the packet acquisition unit 524 starts collecting communication packets, and acquires communication packets flowing on the network in step S92.

  Subsequently, in step S93, the packet analysis unit 525 receives the communication packet acquired by the packet acquisition unit 524, and determines whether the communication protocol is HTTP or HTTPS.

  If it is determined that the communication protocol is HTTP or HTTPS, the packet analysis unit 525 proceeds to step S94 and refers to the excluded file extension table 522. In step S95, the packet analysis unit 525 determines whether or not the history exclusion file extension is included in the file request information included in the communication packet based on the reference result.

  When it is determined that the history exclusion file extension is not included in the file request information, the packet analysis unit 525 proceeds to step S96 and creates a file request history. Then, the packet analysis unit 525 records the created history in the history recording unit 526.

  Next, in step S97, the packet analysis unit 525 refers to the flag value recording unit 523. In step S98, the packet analysis unit 525 determines whether the flag value is FALSE based on the referred result.

  When it is determined that the flag value is FALSE, the packet analysis unit 525 interrupts the history collection in step S99 and ends the process illustrated in FIG. That is, as described in step S75 in FIG. 8, when the history collection setting unit 521 sets (or records) the flag value as FALSE, the history collection is interrupted. If it is determined that the flag value is TRUE, the packet analysis unit 525 returns the process to step S92.

If the packet analysis unit 525 determines in step S95 that the history request file extension is not included in the file request information, the process proceeds to step S97. Subsequent processing is the same as the processing described above.
That is, the packet analysis unit 525 controls whether to create (and store) a history based on the determination result in step S95.

  If the packet analysis unit 525 determines in step S93 that the communication protocol is not HTTP or HTTPS, the process proceeds to step S97. Subsequent processing is the same as the processing described above.

  When the history browsing unit 527 receives the browsing request, the history browsing unit 527 displays the history stored in the history recording unit 526. As an example, FIG. 11 shows an example of a history browsing screen displaying a history when a user of the information browsing apparatus 51 browses the top page of a homepage when the history exclusion file extension is not set. Show. FIG. 11 is a diagram illustrating an example of a history browsing screen when the history exclusion file extension is not set.

  On the other hand, as another example, an example of a history browsing screen displaying a history when the user of the information browsing device 51 browses the top page of a homepage when the history exclusion file extension is not set. Is shown in FIG. FIG. 12 is a diagram illustrating an example of a history browsing screen when a history exclusion file extension has been set.

  As can be seen from FIGS. 11 and 12, by setting the history exclusion file extension, no extra history is recorded, and the storage capacity of the information processing apparatus is reduced, and at the same time, the history contents on the history browsing screen are easy to see.

  As described above, according to the present embodiment, it is possible to selectively create or record an operation history for a highly important file by specifying a file extension that excludes creation and storage of the history.

<Embodiment 2>
Only differences from the first embodiment will be described below.
FIG. 13 is a diagram illustrating an example of a history collection screen according to the second embodiment.
In the history collection screen 1201 of this embodiment, as shown by 1202, a portion (or area) where the user can register an arbitrary history exclusion file extension is added. When the user inputs the file extension of the history exclusion desired by the user in the part, the history collection setting unit 521 sets the newly entered history exclusion file extension in the exclusion file extension table 522.

  As described above, according to the present embodiment, when the user specifies a history exclusion file extension desired by the user, when the file extension is included in the file request, the history related to the file request is not recorded. Can do.

<Embodiment 3>
Only differences from the first embodiment will be described below.
FIG. 14 is a diagram illustrating an example of a system configuration and a functional configuration of the information processing apparatus 52 according to the third embodiment.

  In the functional configuration of the information processing apparatus 52 according to the third embodiment, a ratio analysis unit 529 is newly added as a functional configuration. In the functional configuration of the information processing apparatus 52 of the third embodiment, the portion that was the excluded file extension table 522 in the first embodiment is replaced with the history exclusion ratio storage unit 528.

FIG. 15 is a diagram illustrating an example of a history collection screen according to the third embodiment.
The history collection screen 1401 of this embodiment includes a portion (area) in which the ratio of the file extension to the extension of all files can be specified, as indicated by 1402. When the user inputs a ratio in the part, the history collection setting unit 521 sets a ratio (ratio information) in the history exclusion ratio storage unit 528. The ratio stored (or set) in the history exclusion ratio storage unit 528 is stored in the HDD 107 or the like.

  FIG. 16 is a flowchart illustrating an example of a processing flow from acquisition of a communication packet to recording of a history according to the third embodiment. The difference between the flowchart shown in FIG. 16 and the flowchart shown in FIG. 10 of the first embodiment is the processing from step S1504 to step S1507.

  In step S1504, the packet analysis unit 525 determines whether or not the cumulative number of file requests exceeds a predetermined value (for example, 10,000) (step 1507).

  More specifically, when the packet analysis unit 525 receives a communication packet from the packet acquisition unit 524 and determines that the communication protocol is HTTP or HTTPS, the packet analysis unit 525 counts up the cumulative number of file requests (request count counting). In step S1504, the packet analysis unit 525 determines whether or not the cumulative number of file requests exceeds a predetermined value (for example, 10,000).

  If the packet analysis unit 525 determines that the cumulative number of file requests exceeds a predetermined value, the process proceeds to step S1505. If the packet analysis unit 525 determines that the cumulative number of file requests does not exceed the predetermined value, the packet analysis unit 525 proceeds to step S1508. move on.

  Note that the packet analysis unit 525 also counts up the cumulative number of file requests for each file extension (for each file attribute information) (request count for each attribute information).

  In step S1508, the packet analysis unit 525 creates a file request history. Then, the packet analysis unit 525 records the created history in the history recording unit 526.

  On the other hand, in step S1505, the ratio analysis unit 529 obtains the ratio between the total number of file requests for each file extension counted by the packet analysis unit 525 and the total number of all file requests.

  Subsequently, in step S1506, the ratio analysis unit 529 refers to the history exclusion ratio storage unit 528. In step S1507, the ratio analysis unit 529 determines whether the ratio obtained in step S1505 exceeds the history exclusion ratio recorded in the history exclusion ratio storage unit 528 based on the referred result.

  If the ratio analysis unit 529 determines that the ratio obtained in step S1505 exceeds the history exclusion ratio recorded in the history exclusion ratio storage unit 528, the process proceeds to step S1509. On the other hand, if the ratio analysis unit 529 determines that the ratio obtained in step S1505 does not exceed the history exclusion ratio recorded in the history exclusion ratio storage unit 528, the process proceeds to step S1508.

The subsequent processing is the same as in the first embodiment.
That is, the packet analysis unit 525 (or the ratio analysis unit 529) controls whether to create (and store) a history based on the determination result in step S1507.

  As described above, in the present embodiment, the information processing apparatus 52 accumulates the number of file extension requests included in the acquired file request for each type of file extension. The information processing apparatus 52 also accumulates the total number of acquired file requests. Then, when the total number of requests exceeds a predetermined value, the information processing apparatus 52 accumulates the total number of requests (count value) and the total number of requests (count value) for each file extension. To find the ratio.

  Then, the information processing apparatus 52 determines whether or not this ratio exceeds the history exclusion ratio set by the user, and if it exceeds, controls to not create or record a history.

  In the example described above, 10,000 is exemplified as the predetermined value. However, the numerical value may be anything, and may be a fixed period without being a fixed number. Further, the user may be able to specify an arbitrary numerical value or period.

<Embodiment 4>
