I will provide a. Hereinafter, these functions are referred to as a web filtering function and an application filtering function.

  What kind of web page or application is considered “undesirable” can be left to the management server 10 or can be designated by the management user operating the management terminal 30. The administrative user may be a person different from the user of the mobile terminal 20 or the same person. For example, when the youth uses the mobile terminal 20, the guardian becomes a management user, the web page or application that the guardian thinks is not desirable for the youth is designated from the management terminal 30, and browsing of the web page or use of the application is performed. Can be limited.

  5 and 6 are diagrams showing examples of tables stored in the database 15.

  The web classification table 61 shown in FIG. 5A is a table that associates the URL matching pattern 61a with the URL category group 61b of the web page specified by the matching pattern. When the URL of a specific web page matches the URL matching pattern 61a stored in the web classification table 61, the management server 10 represents the web page by the corresponding URL category group 61b. Classify into each URL category. That is, one web page may belong to a plurality of URL categories. Note that the collation method between the URL and the URL collation pattern 61a does not have to be forward coincidence. For example, pattern matching using a regular expression or the like may be performed.

  The application classification table 62 shown in FIG. 5B is a table that associates the application identification ID 62a with the application category group 62b of the application specified by the application identification ID. When the application identification ID of a specific application matches one of the application identification IDs 62a stored in the application classification table 62, the management server 10 designates the application as each application represented by the corresponding application category group 62b. Classify into categories. That is, one application may belong to a plurality of application categories.

  The URL category and the application category may be the same or different. For example, there may be a category that exists in the application category but does not exist in the URL category.

  The system application determination table 63 shown in FIG. 5C is a table that associates a terminal model ID 63a that is a unique identifier for each model (model) of the mobile terminal 20 with the application identification ID 63b of the system application in the model. . When the terminal model ID of a specific mobile terminal 20 matches one of the terminal model IDs 63a stored in the system application determination table 63, the management server 10 The application represented by the corresponding application identification ID 63b is determined to be a system application.

  The web automatic filtering table 64 illustrated in FIG. 6A is a table that associates a terminal identification ID 64a that is a unique identifier for each mobile terminal 20, the URL category 64b, and the browsing availability 64c of the URL category. The browsing permission / inhibition 64c is one of “permitted” and “prohibited”.

  The application automatic filtering table 65 illustrated in FIG. 6B is a table that associates the terminal identification ID 65a, the application category 65b, and the availability 65c of the application category. The availability 65c is a value of either “permitted” or “prohibited”.

  The application filtering setting table 66 illustrated in FIG. 6C is a table that associates the terminal identification ID 66a, the application identification ID 66b, the new flag 66c, and the availability setting 66d. The availability setting 66d is any one of “permitted”, “prohibited”, and “automatic”.

  In addition, although terminal identification ID demonstrated that it was unique for every portable terminal 20, it should just be unique among portable terminals 20 using the filtering system 1, and does not need to be unique among all portable terminals 20. FIG. The terminal identification ID may be, for example, an identifier written in the ROM 23 of the mobile terminal 20 when the mobile terminal 20 is manufactured, or may be a telephone number assigned to the mobile terminal 20. Or the identifier produced | generated at the time of the first time use of the filtering system 1 in the management server 10 or the portable terminal 20 may be sufficient.

  Next, a method for providing a web filtering function using each table described above and a method for providing an application filtering function will be described in order.

  FIG. 7 is a flowchart of the web filtering process. The web filtering process (steps S10 to S80) executed by the CPU 21 of the mobile terminal 20 is performed on the left side of FIG. 7 and the web filtering process (steps S110 to S160) performed by the CPU 11 of the management server 10 is performed on the right side of FIG. Are shown respectively.

  First, the web filtering process which CPU21 of the portable terminal 20 performs is demonstrated. In step S <b> 10, the CPU 21 accepts a URL input from the operation unit 26. In step S <b> 20, the CPU 21 transmits the URL received in step S <b> 10 and the terminal identification ID of the mobile terminal 20 to the management server 10 via the communication unit 24. In step S <b> 30, the CPU 21 receives browsing permission data from the management server 10 via the communication unit 24. The browsing availability data is a value of either “permitted” or “prohibited”.

  In step S40, the CPU 21 determines whether or not the viewability data received in step S30 is “permitted”. If the received browsing permission data is “permitted”, the CPU 21 advances the process to step S50. In step S50, the CPU 21 transmits request data for requesting data represented by the URL to the web server 40 corresponding to the URL received in step S10 via the communication unit 24. In step S <b> 60, the CPU 21 receives response data corresponding to the request data transmitted in step S <b> 50 from the web server 40 via the communication unit 24. In step S70, the CPU 21 displays the contents of the web page on the display unit 25 based on the response data received in step S60.

  On the other hand, when the browseability data received in step S30 is “prohibited”, the CPU 21 advances the process to step S80. In step S80, the CPU 21 displays a non-permission page including a message indicating that browsing is not permitted on the display unit 25 instead of the web page represented by the URL received in step S10.

  Next, web filtering processing executed by the CPU 11 of the management server 10 will be described. In step S <b> 110, the CPU 11 receives the URL and the terminal identification ID from the portable terminal 20 via the communication unit 14. In step S120, the CPU 11 inquires the web classification table 61 in the database 15 by the received URL, and determines whether or not the received URL matches any URL matching pattern 61a.

  If it matches any of the URL matching patterns 61a, the CPU 11 advances the process to step S130. In step S130, the CPU 11 extracts the URL category group 61b corresponding to the matched URL matching pattern 61a from the web classification table 61, and specifies the URL category (one or more) to which the received URL belongs. In step S140, the CPU 11 searches for the terminal identification ID received from the web automatic filtering table 64 in the database 15, and specifies whether or not the URL category specified in step S130 is viewable 64c. That is, the web automatic filtering table 64 is searched for a line in which the terminal identification ID 64a is the received terminal identification ID and the URL category 64b is the URL category specified in step S130, and the browsing availability 64c in the line is retrieved. The CPU 11 determines whether or not the URL received in step S110 is viewable based on the viewability 64c specified here.

  If one URL belongs to a plurality of URL categories, a plurality of browsing proprieties 64c are extracted in step S140. If any one of the plurality of browsing availability 64c is “prohibited”, the CPU 11 prohibits browsing the URL. Then, in step S <b> 160, the CPU 11 transmits browsing propriety data indicating the browsing propriety determined in step S <b> 140 to the mobile terminal 20.

  On the other hand, if the received URL does not match the URL matching pattern 61a of the web classification table 61 in step S120, the CPU 11 advances the process to step S150. In step S150, the CPU 11 determines browsing permission, and transmits browsing permission data indicating “permission” to the portable terminal 20 in step S160.

  FIG. 8 is a flowchart of the application filtering process. The application filtering process (step S210) executed by the CPU 21 of the mobile terminal 20 is performed on the left side of FIG. 8 and the application filtering process (steps S310 to S420) executed by the CPU 11 of the management server 10 is performed on the right side of FIG. Each is illustrated.

  First, application filtering processing executed by the CPU 21 of the mobile terminal 20 will be described. The CPU 21 executes the processing shown on the left side of FIG. 8 at a predetermined timing (for example, every time a new application is installed, when requested by the management server 10). First, in step S <b> 210, the CPU 21 transmits a terminal identification ID of the mobile terminal 20, a terminal model name, and a list of application identification IDs of installed applications to the management server 10 via the communication unit 24. In step S <b> 220, the CPU 21 receives availability data for each installed application and stores it in the ROM 23. Each availability data is either “permitted” or “prohibited”.

  Thereafter, the CPU 21 refers to the availability data stored in the ROM 23 every time the user tries to activate the application. If the availability data of the application for which activation has been attempted is “prohibited”, activation of the application is prohibited, and the display unit 25 displays that the application is prohibited.

  Next, application filtering processing executed by the CPU 11 of the management server 10 will be described. First, in step S <b> 310, the CPU 11 receives a terminal identification ID of the mobile terminal 20, a terminal model name, and a list of installed application identification IDs from the mobile terminal 20 via the communication unit 14.

  In step S320, the CPU 11 updates the application filtering setting table 66 in the database 15 with each data received in step S310. Specifically, if a row corresponding to the combination of the received terminal identification ID and application identification ID does not exist in the application filtering setting table 66, that is, if a new application is installed in the mobile terminal 20, a new Are added to the application filtering setting table 66. At this time, the terminal identification ID 66a and the application identification ID 66b are set to the received values, the new flag 66c is set to the flagged state, and the availability setting 66d is set to “automatic”. Further, for the other rows corresponding to the received terminal identification ID, the new flag 66c is set in a state where the flag is cleared. That is, the new flag 66c is information indicating whether or not the application is newly added since the previous acquisition of the application list.

  In the application filtering setting table 66, when there is a line corresponding to the application identification ID 66b that is not included in the list of received application identification IDs among the lines corresponding to the received terminal identification ID, that is, from the mobile terminal 20 to the application May be deleted from the application filtering setting table 66 in step S320.

  In step S330, the CPU 11 selects one of the application identification IDs received in step S310. In step S340, the CPU 11 determines whether or not the application specified by the selected application identification ID is a system application. The CPU 11 determines whether or not the application is a system application by searching the system application determination table 63 with the terminal model name received in step S310 and the selected application identification ID. If the app is a system app, the CPU 11 advances the process to step S350 to determine permission to use the app.

  On the other hand, if the app is not a system app, the CPU 11 advances the process to step S360. In step S360, the CPU 11 searches the application filtering table for a line corresponding to the received terminal identification ID and the selected application identification ID, and retrieves the availability setting 66d of the line. If the extracted use permission / inhibition setting 66d is “permitted”, the CPU 11 advances the process to step S350, and determines permission to use the application. On the other hand, when the extracted use permission / inhibition setting 66d is “prohibited”, the CPU 11 advances the process to step S400 and determines the use prohibition of the application. On the other hand, if the extracted availability setting 66d is “automatic”, the CPU 11 advances the process to step S370.

  In step S <b> 370, the CPU 11 determines whether a row corresponding to the selected application identification ID exists in the application classification table 62. When the line corresponding to the selected application identification ID exists in the application classification table 62, the CPU 11 advances the process to step S380. In step S380, the CPU 11 extracts the application category group 62b corresponding to the selected application identification ID from the application classification table 62, and identifies the application category (one or more) to which the application belongs. In step S390, the CPU 11 searches the application automatic filtering table 65 for a line corresponding to the received terminal identification ID and the application category specified in step S380, and extracts the availability 65c. If at least one “prohibited” is included in the extracted one or more use availability 65c, the CPU 11 determines use prohibition of the application. On the other hand, if all of the extracted one or more use availability 65c are “permitted”, the CPU 11 determines the use permission of the application.

  If the line corresponding to the application identification ID selected in step S370 does not exist in the application classification table 62, that is, if the application category of the application is unknown, the CPU 11 advances the process to step S400. In step S400, the CPU 11 determines prohibition of use of the application.

  In step S410, the CPU 11 determines whether or not all applications have been selected, that is, whether or not the processes from steps S330 to S400 have been executed for all applications. If an unselected application remains, the CPU 11 returns the process to step S330. On the other hand, when the process has been completed for all applications, the CPU 11 advances the process to step S420. In step S <b> 420, the CPU 11 transmits availability data of each application to the mobile terminal 20 via the communication unit 14.

  Next, the management screen of the portable terminal 20 by the management terminal 30 will be described. The management user can connect to the management server 10 using the management terminal 30 and display the management screen of the portable terminal 20 (one or more) on the display unit 35. The management screen may be displayed by, for example, a web browser, or dedicated software for displaying the management screen may be prepared in the management terminal 30.

  9 and 10 are diagrams illustrating an example of the management screen. The first management screen 70 shown in FIG. 9 exists for each mobile terminal 20 under management. The management user can switch the portable terminal 20 to be displayed by operating the operation unit 36. In the upper left of the first management screen 70, the terminal identification ID of the mobile terminal 20 that is the target of the first management screen 70 currently displayed is displayed.

  The first management screen 70 includes an area 71 for displaying a list of permission / prohibition settings for each URL category and an area 72 for displaying a list of permission / prohibition settings for each application category. When the management user operates the operation unit 36 to change the permission / prohibition setting of the URL category or the permission / prohibition setting of the application category, the CPU 11 of the management server 10 can browse the web automatic filtering table 64 in the database 15 64c. Alternatively, the availability 65c of the application automatic filtering table 65 is changed to a value corresponding to the operation. That is, the management user can edit the web automatic filtering table 64 and the application automatic filtering table 65 using the first management screen 70.

  Similarly to the first management screen 70, the second management screen 80 shown in FIG. 10 exists for each mobile terminal 20 under management. The management user can switch the portable terminal 20 to be displayed by operating the operation unit 36. On the upper left of the second management screen 80, the terminal identification ID of the mobile terminal 20 that is the target of the second management screen 80 currently displayed is displayed. On the second management screen 80, a list of applications installed in the mobile terminal 20 to be displayed is displayed. The system application is not displayed on the second management screen 80.

  The second management screen 80 includes an area 81 where a list of newly installed applications is displayed and an area 82 where a list of other applications is displayed. The CPU 11 of the management server 10 displays a list of applications in the former area 81 and the latter area 82 based on the new flag 66 c in the application filtering setting table 66. That is, an application with the new flag 66c is displayed in the former area 81, and an application with the new flag 66c is displayed in the latter area 82. The latter area 82 further includes an area 83 where a list of currently prohibited (restricted) applications is displayed and an area 84 where a list of currently permitted applications is displayed.

  In each of the areas 81, 83, and 84, an application identification ID for specifying an application and a setting for availability of use of the application are displayed in a list. When the management user operates the operation unit 36 and changes the availability setting of each application, the CPU 11 of the management server 10 sets the availability setting 66d of the application filtering setting table 66 in the database 15 to a value corresponding to the operation. change. That is, the management user can edit the application filtering setting table 66 using the second management screen 80.

  An update button 85 is further arranged on the second management screen 80. When the management user operates the operation unit 36 and presses the update button 85, the CPU 11 of the management server 10 requests the mobile terminal 20 to be displayed to transmit an application list. In response to this request, the CPU 21 of the portable terminal 20 starts executing the processing shown in FIG. Similarly, the CPU 11 of the management server 10 starts executing the processing shown in FIG. 8 and then updates the display content of the second management screen 80.

  In addition, the display content of the 1st management screen 70 and the 2nd management screen 80 may differ from what was shown in FIG. 9 and FIG. For example, a preset nickname may be displayed instead of the terminal identification ID, or an application name may be displayed instead of the application identification ID. Further, the system application may be displayed on the second management screen 80. However, it is necessary not to change the system application availability setting.

According to the filtering system according to the first embodiment described above, the following operational effects can be obtained.
(1) The CPU 11 of the management server 10 receives an application identification ID related to an application program installed in the mobile terminal 20 from the mobile terminal 20 via the communication unit 14, and determines whether or not the application program can be used in the mobile terminal 20. Then, information regarding the availability of the application program is transmitted to the mobile terminal 20 via the communication unit 14. Since it did in this way, utilization of a harmful application program in portable terminal 20 is prohibited, and it becomes possible to protect a user of portable terminal 20 more certainly.

(2) The CPU 11 receives the application identification ID and the terminal model name that identifies the model of the mobile terminal 20 via the communication unit 14, and an application program is necessary for the operation of the mobile terminal 20 based on the terminal model name. It is determined whether the system program is correct. When it is determined that the application program is a system program, the CPU 11 permits the use of the application program. Since it did in this way, the system program required for operation | movement of the portable terminal 20 is prohibited, and the operation | movement of the portable terminal 20 is not disturbed. In addition, the management user does not need to individually set permission for a large number of system programs, and operability is improved.

(3) The management server 10 includes a database 15 that stores an application classification table 62. The application classification table 62 includes a plurality of sets of an application identification ID 62a and an application category group 62b including one or more application categories to which the application program specified by the application identification ID 62a belongs. The CPU 11 searches the application classification table 62 for the application identification ID 62a received from the mobile terminal 20 via the communication unit 14, and identifies one or more application categories to which the application program belongs. Then, based on the identified application category, the availability of the application program is determined. Since it did in this way, it can be discriminate | determined rapidly whether a certain application program belongs to a harmful category. Further, by updating the application classification table 62, it is possible to promptly respond to a new application program.

(4) The database 15 stores an application automatic filtering table 65. The application automatic filtering table 65 includes a plurality of sets of terminal identification ID 65a and application categories 65b permitted or prohibited in the mobile terminal 20 identified by the terminal identification ID 66a. The CPU 11 receives an application identification ID, a terminal model name that identifies the model of the portable terminal 20, and a terminal identification ID that identifies the portable terminal 20 via the communication unit 14. Then, the received terminal identification ID 65a is searched from the application automatic filtering table 65, the application category 65b permitted or prohibited is specified, one or more application categories to which the application program belongs, and the application categories permitted or prohibited. Whether to use the application program is determined based on the comparison result with 65b. Since it did in this way, use permission of an application can be defined for every portable terminal 20 and every application category, and control of flexible use permission is attained. Also, app availability can be set in a batch for each app category, reducing the management load on the management user.

  The following modifications are also within the scope of the present invention, and one or a plurality of modifications can be combined with the above-described embodiment.

(Modification 1)
