Description

  The present invention relates to an information processing system, an information processing apparatus, and a program.

In recent years, online shopping and net banking services using the Internet and the like have become widespread. A website providing such a service sets a unique security policy, and a connection relationship between a management server on the website side and an information terminal device on the user side (for example, a personal computer, a mobile phone, etc.) , Called “session”) is managed. For example, an expiration date is set for the session, and when the expiration date has passed, the session is disconnected and the user is authenticated again to maintain security.
For example, Patent Document 1 discloses a network system capable of notifying a user of a timeout and extending the session expiration date before the session expiration date expires.

Note that the presence information stored in the storage unit 53 is preferably a database stored for a predetermined period (for example, 1 hour, 1 day, etc.). However, the means for storing presence information is not limited to this.

  The presence management DBMS 5 configured as described above stores, for example, presence information transmitted from the presence server device 3 and transmits desired presence information requested from the presence server device 3. As a result, the presence server 3 device can appropriately manage user presence information.

Next, an operation of processing executed by the information processing system according to the present embodiment will be described with reference to FIG. As described above, the presence input unit 14 of the client device 1 acquires presence information indicating the state of the user, and the communication unit 16 transmits the acquired presence information via the communication network 6 according to an instruction from the control unit 12. To the presence server device 3 sequentially.
In the present embodiment, the presence input unit 14 periodically acquires presence information acquired by a human sensor or a web camera at a predetermined time interval (for example, every second, every 10 seconds, etc.) The control unit 12 transmits the acquired presence information to the presence server device 3 through the communication unit 16.

(User authentication process)
The user accesses a predetermined website via the communication network 6 by operating a keyboard, a mouse, or the like included in the input unit 11 of the client device 1.
First, the control unit 12 of the client device 1 cooperates with the communication unit 16 to transmit a signal requesting user authentication, user identification information, and a password to the web server device 2 (step S101).

  When the control unit 21 of the web server device 2 receives the signal requesting user authentication, the user identification information, and the password received by the communication unit 22, the control unit 21 transmits a signal requesting the presence information of the user indicated by the user identification information to the presence server. It transmits to the apparatus 3 (step S102).

  The control unit 31 of the presence server device 3 transmits the user presence information indicated by the user identification information to the web server device 2 based on the presence information sequentially received from the client device 1 (step S103). The web server device 2 acquires the user's current presence information.

  The control unit 21 of the web server device 2 sets a default timeout value (for example, 5 minutes) (step S104).

  The control unit 21 of the web server device 2 performs user authentication, and transmits the authentication result to the client device 1 via the communication unit 22 (step S105). For example, the control unit 21 determines whether or not the combination of the received user identification information and the password is correct based on data in which the user identification information and the password stored in the storage unit 23 are associated with each other. I do.

  When the connection is permitted by the user authentication, the control unit 12 of the client device 1 transmits a signal requesting the website content to the web server device 2 via the communication unit 16 (step S106). If the connection is not permitted by the user authentication, the control unit 12 returns to step S101 and performs the process of requesting the user authentication again.

  The control unit 21 of the web server device 2 acquires the session management information 60 appropriate for the content from the session management DBMS 4 based on the content requested from the client device 1 and the presence information acquired in step S103 ( Step S107).

For example, FIG. 9 is a diagram illustrating an example of the session management information 60 stored in the session management DBMS 4. In addition, this figure is the session management information 60 supposing the case where online shopping using the internet etc. is performed. As shown in this figure, the session management information 60 stores session contents and management information in association with each other. The management information defines session timeouts when the user's presence is continued and when the user's presence is interrupted based on the presence information transmitted from the client device 1.
Here, the case where the presence is continued is, for example, “the user is sitting in front of the client device 1”, “the user keeps browsing the same page”, and the presence is interrupted. For example, “the user is no longer in front of the client device 1” or the like.

  The control unit 21 acquires and sets, for example, a timeout value in the case of continuation of presence from the session management information 60 as an initial value of the session timeout value of the content requested by the user (step S108). Then, the control unit 21 transmits the requested content to the client device 1 via the communication unit 22 (step S109).

(Session management processing)
Next, an operation of session management processing executed by the information processing system according to the present embodiment will be described.

First, based on the user status sensed by the presence input unit 14 of the client device 1, the control unit 12 detects that the presence of the user has changed (step S201).
For example, the presence change is detected by a human sensor (for example, a contact sensor, an optical sensor, or the like) or a web camera installed at a predetermined position when the user stops or stops using the client device 1. Is detected by

Next, the control unit 12 of the client device 1 controls the communication unit 16 to transmit a signal indicating that the presence of the user has changed and presence information to the presence server device 3 (step S202).
Alternatively, the control unit 12 may be configured to transmit presence information at a predetermined timing (for example, every minute) regardless of whether or not the user's presence has changed.

  The control unit 31 of the presence server device 3 stores the user's presence information in the storage unit 33, and transmits information indicating that the user's presence has been changed to the web server device 2 via the communication unit 32 (Step S31). S203).

  The control unit 21 of the web server device 2 determines which page the user is currently browsing (step S204). For example, the control unit 21 determines a browsing page or the like based on the content requested last from the client device 1.

  The control unit 21 of the web server device 2 acquires the session timeout value most appropriate for the session content currently being stretched from the session management information 60 stored in the session management DBMS 4 (step S205). Then, the control unit 21 sets the acquired session timeout value as an initial value of the session expiration date (step S206).

For example, it is assumed that the session management information 60 has the contents shown in FIG. When the management information corresponding to the session content exists in the session management information 60, the web server device 2 acquires the session timeout value of “in the case of continuation of presence” from the session management DBMS 4. The web server device 2 sets the acquired value as the initial value of the session expiration date. Note that if there is no management information corresponding to the session content, a predetermined default value (for example, 5 minutes) may be set.
When the same session content continues, the control unit 21 maintains the session timeout value as the initial value. Further, when moving to a different session content, the control unit 21 changes the session timeout value to a corresponding value.

For example, when the user requests content for “viewing a fashion catalog” and the user's presence continues, the web server device 2 responds based on the set expiration date (in this case, 30 minutes). To continue processing.
For example, when the presence of the user is interrupted, the web server device 2 acquires management information indicating the expiration date (in this case, 5 minutes) of the corresponding session and sets the session timeout value. At this time, it is desirable to adopt the smaller one of the remaining time of the expiration date set before and the expiration date in the case of presence interruption. When the user's presence is resumed, the web server device 2 may set the session expiration date to the initial value again.
Alternatively, for example, when the user browses a page corresponding to “settlement” and the user's presence is interrupted, the web server device 2 acquires management information indicating that the session is immediately disconnected from the session management DBMS 4. . The web server device 2 disconnects the currently established session and notifies the client device 1 that it is a session timeout. In this case, it is desirable that the web server device 2 performs the above-described user authentication process again, sets the session expiration date to an initial value after authentication, and re-establishes the session.

  However, the session management information 60 is not limited to that described above. That is, the session management information 60 only needs to be stored in association with the content provided to the user and the session expiration date. Further, the information stored in the session management information 60 can be variously improved, such as a logical expression expressed by a logical sum of predetermined events or a specific mathematical expression. Further, it may be realized as a program or the like provided with information corresponding to the session management information 60 in advance.

When the control unit 21 of the web server device 2 receives a content processing request from the client device 1 (step S207), the control unit 21 determines whether the session has expired (step S208). For example, the control unit 21 obtains the history information of the user who has requested the content processing from the storage unit 23 and obtains the elapsed time of the session. Then, the control unit 21 determines whether or not the session of the user who has requested the content processing is within the expiration date based on the elapsed time of the session and the management information acquired from the session management DBMS 4.
If it is within the session timeout value set in step S206 (step S208; YES), the requested content is processed and the content is transmitted (step S209). That is, the control unit 21 receives a request for processing related to content (for example, “fashion catalog browsing”, etc.) from the client device 1, and in the case of a predetermined process (for example, “fashion catalog browsing”), Search for and obtain relevant product information, etc.).
Alternatively, when the set session timeout value is exceeded (step S208; NO), the client device 1 is notified that the session timeout has occurred, and user authentication is performed as in step S105 (step S210). In this case, it is desirable that the control unit 21 performs the above-described user authentication process again and re-establishes a session.
The content processing request by the client device 1 (step S207) and the content processing by the web server device 2 (step S208) are repeatedly executed by the user while the session continues. When the session ends, the session management process ends.

  In this embodiment, the client device 1 notifies the presence server device 3 that the presence information has changed when the presence information has changed, but the present invention is not limited to this. . That is, the client device 1 may transmit the presence information at regular time intervals regardless of whether or not the presence information has changed.

  Thus, the information processing system performs session management processing. As described above, the process of transmitting presence information from the client apparatus 1 to the presence server apparatus 3 is performed as a process independent of the process of providing content from the client apparatus 1 by the web server apparatus 2. As a result, the user can receive the content without being aware that the session timeout value of the content is set based on the transmitted presence information.

  In addition, since the session timeout value is determined based on the presence information of the user, for example, when the user leaves the seat, it is possible to prevent an accident in which another person may operate without permission. And higher security can be ensured.

(Embodiment 2)
In the present embodiment, when the web server device 2 receives a content processing request from a user, the current presence information of the user is acquired and session management is performed. Note that the configurations of the client device 1, the web server device 2, and the presence server device 3 are the same as those in the above-described embodiment, and thus description thereof is omitted.
In the present embodiment, the presence input unit 14 of the client device 1 periodically acquires the presence information acquired by a human sensor or a web camera at a predetermined time interval (for example, every 1 second, every 10 seconds, etc.). Upon acquisition, the control unit 12 transmits the acquired presence information to the presence server device 3 via the communication unit 16.

FIG. 10 is a diagram illustrating session management processing executed by the information processing system according to this embodiment.
First, the control unit 21 of the web server device 2 accepts a content processing request from the client device 1 (step S301).

  The control unit 21 requests transmission of the current presence information of the user who has requested the content processing (step S302).

  The control unit 31 of the presence server device 3 transmits the current presence information (or presence information closest to the current time) of the corresponding user to the web server device 2 (step S303).

  As in the above-described embodiment, the control unit 21 determines which page the user is currently browsing (step S304).

  Based on the presence information acquired in step S303, the control unit 21 acquires from the session management DBMS 4 the session management information 60 that is most appropriate for the current session content (step S305).

  Based on the acquired session management information 60, the control unit 21 changes the session timeout value corresponding to the page that the user is browsing (step S306).

  The control unit 21 determines whether the validity period of the currently established session has expired (step S307).

If the session has not expired (step S307; YES), the control unit 21 processes the requested content and transmits the content (step S308).
On the other hand, if the session has expired (step S307; NO), the control unit 21 requests the client device 1 for user authentication (step S309). That is, when the user authentication process described above is performed and the user is authenticated as an authorized user, the control unit 21 transmits the content.

  As described above, according to the present embodiment, the latest presence information can be acquired for each content processing request, and the session can be managed using the optimum expiration value, thereby further improving security. .

The present invention is not limited to the above-described embodiments, and various modifications and applications are possible.
For example, the presence input unit 14 of the client device 1 can be configured to function by an input device such as a keyboard or a mouse provided in the input unit 11. In this case, for example, the control unit 12 determines whether or not an input device such as a keyboard or a mouse included in the input unit 11 is operated, and determines that it has not been operated for a predetermined time (for example, 10 minutes, 1 hour, etc.). In this case, presence information indicating that “the user is not in front of the client device 1” is transmitted to the web server device 2.

  For example, when a mobile terminal device (for example, a mobile phone, a PDA (Personal Digital Assistance) or the like) is adopted as the client device 1 and the control unit 12 opens the flip of the mobile terminal device, the “user is operating” Presence information indicating that “there is” is transmitted, and when the flip is closed, presence information indicating that “the user has finished the operation” may be transmitted.

  In addition, when position information acquisition means such as GPS (Global Positioning System) is installed and the client device 1 exists within a predetermined area, presence information indicating that “the user is operating” is transmitted, When the user is away from the vicinity, presence information indicating that “the user has finished the operation” may be transmitted.

  Alternatively, the presence input unit 14 may be configured by combining the above-described human sensor, web camera, input device, GPS, and the like.

In the present embodiment, the presence server device 3 and the presence management DBMS 5 are configured as separate devices. However, the presence server device 3 and the presence management DBMS 5 may be configured as one server device having these functions.
Similarly, the web server device 2 and the session management DBMS 4 are configured as separate devices, but may be configured as a single server device having these functions.
Furthermore, you may comprise as one server apparatus which has all the functions of the web server apparatus 2, session management DBMS4, presence server apparatus 3, and presence management DBMS5. However, in consideration of load distribution, it is desirable to separately configure a server that performs processing related to content provision and a server that performs processing for managing presence information.

  In the above embodiment, the program has been described as being prestored in the storage unit 15 or the like. However, a program for operating the web server device 2 or the like as all or part of the device or executing the above-described processing is stored in a memory card, a CD-ROM (Compact Disc Read-Only Memory), a DVD (Digital Versatile Disk (MO) or Magneto Optical Disk (MO) is stored and distributed on a computer-readable recording medium, which is installed on another computer and operated as the above-mentioned means, or the above-described steps are executed. Also good.

  Furthermore, the program may be stored in a disk device or the like included in a server device on the Internet, and may be downloaded onto a computer by being superimposed on a carrier wave, for example.
