Description

  The present invention relates to a terminal control server, a terminal control system, and a terminal control method.

  After the enforcement of the Personal Information Protection Law (2005), personal information leakage accidents due to loss of mobile terminals, etc. have become a social problem, and countermeasures against information security by companies have become an important theme. For example, personal information and other company secret information are taken out using a mobile phone, and information leakage occurs due to loss or theft of the mobile phone. In addition, there is an act that a company employee intentionally leaks information, and countermeasures based on the premise that even an employee cannot be trusted are required. When information is leaked by employees, the information is copied using the camera function, external memory function, infrared communication, Bluetooth (registered trademark), IC card peripheral communication function, etc. There are cases such as leaks.

  Due to the above problems, recently, as known in Non-Patent Document 1, for example, mobile phones sold without a camera function, an external memory function, a communication function with peripheral devices, and the like have appeared. ing. Since such a mobile phone does not have a function that leads to information leakage from the beginning, problems such as information leakage by employees cannot occur in the first place, which is useful for companies that place importance on information security.

Further, the above-mentioned document also discloses a function of deleting all data in the mobile phone by remote control. In this case, even if the mobile phone is lost, it is possible for a company or the like who attaches importance to information security because it is possible to delete data that leads to leakage of personal information from a remote location.

  However, in order to ensure security, in addition to the remote deletion of the personal information, a plurality of remote controls such as a camera function, an external memory function, a communication function with peripheral devices, etc. may be required. In such a case, it is assumed that a plurality of remote controls are simultaneously executed for one mobile phone, and it is unclear in which order the remote controls are performed because the plurality of remote controls compete. In such a case, the remote control instructor may perform unintended control, which may lead to information leakage.

  For example, in order to prevent information leakage, it is assumed that the camera function is disabled and the external memory is erased remotely at a specific location. In this case, if both controls compete, for example, when the camera function is disabled after erasing the external memory, there is a possibility that an image taken by the camera after erasing the external memory remains in the external memory. . Even if the camera function is invalidated, an image taken before the invalidation remains in the external memory, and thus information leakage may occur. On the other hand, this problem does not occur when the external memory is erased after the camera function is disabled.

  The terminal management unit 220 is a part that performs communication control necessary for remotely managing the mobile terminal 10. In this embodiment, OMA-DM is used for terminal management, and the terminal management unit 220 has an OMA-DM server function.

  The control unit 230 is a part for remotely restricting operations of a plurality of functions mounted on the mobile terminal 10. As shown in FIG. 4, the control unit 230 includes a storage unit 231 (storage unit), a reception unit 232 (command reception unit, parameter reception unit), a terminal state confirmation unit 233 (terminal state confirmation unit), and a specific information generation unit 234. (Specific information generating means), a priority determining unit 235 (priority determining means), and an execution information generating unit 236 (execution information generating means).

  The storage unit 231 stores an order definition file in which relative priorities among a plurality of control functions are recorded. The control function is a function for restricting all or a part of the operation of the functions mounted on the mobile terminal 10 such as stopping, disabling, or erasing recording for any function currently controlled by the mobile terminal 10. . As an example of the control function, for example, there is a function of erasing all the contents recorded in the external memory of the mobile terminal 10 and resetting the external memory. A function for invalidating the camera function and a function for stopping the USB function or the voice call function can be given as examples of the control function.

  FIG. 5 is a diagram illustrating an example of an order definition file stored in the storage unit 231. In FIG. 5, superiority or inferiority relationships between functions are indicated by symbols such as <,>, =, and the like. That is, the description “control function A> control function B” in the second row and third column (indicated by “* 1” in FIG. 5) of FIG. Higher than priority ". In addition, the description “control function C <control function A” in the fourth row and first column in FIG. 5 (indicated by “* 2” in FIG. 5) is “the priority of control function C is that of control function A. Lower than priority ”. Furthermore, the description “control function D = control function C” in the fifth row and fourth column of FIG. 5 (indicated by “* 3” in FIG. 5) is “priority of control function D and control function C "The priority is equal".

  The priority order as shown in FIG. 5 is determined based on one or more parameters predetermined for each of the plurality of control functions. As one of the parameters, in the present embodiment, after the mobile terminal 10 receives a signal (control function execution information) indicating that an arbitrary control function is executed, the time taken until the control function is actually executed. Is used. This time may be a relative time between a plurality of control functions, for example. Further, as another one of the above parameters, in the present embodiment, the degree of forcing when the mobile terminal 10 executes an arbitrary control function is used. The above time and forcing are selected as having a close relationship with the security importance of the control function, and each parameter value is predetermined for each control function in the system design. It may be. If other parameters are necessary in terms of security of the control function in system design, these parameters may be used as appropriate.

  FIG. 6 is a diagram illustrating an example of parameters used for determining priority in the present embodiment. FIG. 6 shows a parameter X that is a parameter related to the time, a parameter Y that is a parameter related to the forcing, and a parameter Z that is the sum of the parameter X and the parameter Y. For each parameter, a parameter value for each control function is determined in advance, and the higher the parameter value, the higher the importance in terms of security. For example, in the time parameter X, the higher the parameter value, the faster the control function should be executed. In addition, in the forcing parameter Y, the higher the parameter value, the more the control function should be forcibly executed.

  For example, paying attention to the parameter value of the total parameter Z, “control function A (Z value: 9)> control function B (Z value: 8)> control function C (Z value: 3) = control function D (Z value) : 3) ”is established. This superiority / inferiority relationship corresponds to the superiority / inferiority relationship of FIG. That is, FIG. 5 shows the superiority or inferiority relationship when the priority order is determined after all the parameters used in the present embodiment are reflected.

  On the other hand, when attention is paid to the parameter value of the parameter Y, for example, “control function A (Y value: 5)> control function B (Y value: 3)> control function D (Y value: 2)> control function C (Y value: 1) ”is established. This superiority / inferiority relationship is an superiority / inferiority relationship different from the superiority / inferiority relationship when attention is paid to the parameter values of the total parameter Z. The parameter values shown in FIG. 6 are recorded in the order definition file stored in the storage unit 231.

  Returning to FIG. 4, the receiving unit 232 receives instruction information (command) from which the terminal control server 20 becomes a source for remotely controlling the mounted function of the mobile terminal 10 from the instruction terminal 30. This instruction information includes control function specifying information for specifying a control function to be executed by the mobile terminal 10, mobile terminal specifying information for specifying the mobile terminal 10, parameter specifying information for specifying parameters used when determining the priority order, and the like. Can be. The receiving unit 232 outputs the mobile terminal specifying information extracted from the received instruction information to the terminal state confirming unit 233 and the control function executing unit 240, outputs the control function specifying information to the specifying information generating unit 234, and sets the parameter specifying information. It outputs to the priority order judgment part 235.

  The terminal state confirmation unit 233 confirms whether or not the mobile terminal 10 specified by the mobile terminal identification information input from the reception unit 232 has a control function currently being controlled. Receives information (current control function specifying information) for specifying the control function from the mobile terminal 10. The terminal state confirmation unit 233 can grasp the control function currently controlled by the mobile terminal 10 by making an inquiry and response to the mobile terminal 10 through the communication unit 210, for example. The terminal state confirmation unit 233 outputs the received current control function identification information to the identification information generation unit 234.

  The specific information generation unit 234 generates control function specifying information for specifying a control function to be executed by the mobile terminal 10. When the control function specifying information is input from the receiving unit 232, the specific information generating unit 234 uses the control function specifying information as it is, for example, as first control function specifying information. The first control function specifying information may be plural. Further, when the current control function specifying information is input from the terminal state confirmation unit 233, the specific information generating unit 234 sets the current control function specifying information as, for example, second control function specifying information. The second control function specifying information may be plural. The specific information generation unit 234 outputs the control function specific information generated in this way to the priority order determination unit 235. The control function specifying information is a general term for the first control function specifying information, the second control function specifying information, and the like.

  The priority order determination unit 235 determines the priority order among a plurality of control functions by referring to the order definition file stored in the storage unit 231. In order to determine the priority order, the priority order determination unit 235 first specifies each control function based on the control function specification information input from the specification information generation unit 234. For example, the priority order determination unit 235 specifies the first control function from the first control function specifying information and specifies the second control function from the second control function specifying information. Next, the priority order determination unit 235 determines the priority order between the first control function and the second control function with reference to the order definition file as shown in FIGS.

  For convenience of explanation, hereinafter, the first control function is referred to as control function A in FIGS. 5 and 6, and the second control function is referred to as control function B. In this case, the priority order determination unit 235 refers to the rank definition file in FIG. 5 and determines that the priority order of the first control function is higher than the priority order of the second control function. The priority order determination unit 235, for example, from the description “control function A> control function B” in the second row and third column (indicated by “* 1” in FIG. 5) of the order definition file in FIG. It is determined that the priority order of the function A is higher than the priority order of the control function B. This determination is, for example, a determination in the case where a parameter for priority determination is not specifically determined in the command from the instruction terminal 30. In this case, the priority determination unit 235 determines the order definition file in FIG. You can refer to it. Note that the rank definition file in FIG. 5 shows the superiority or inferiority relationship when all of the parameters X and Y in FIG. 6 are reflected, as described above. In addition, even when the command from the instruction terminal 30 describes, for example, that all parameters are satisfied at the same time when priority determination is performed, as described above, the priority determination unit 235 also performs FIG. This determination can be made with reference to the order definition file.

  On the other hand, when parameters for priority determination are determined by the instruction terminal 30, that is, when parameter specifying information is included in the instruction information from the instruction terminal 30, the priority determination unit 235 firstly The parameter is specified from the parameter specifying information input from the receiving unit 232. Next, parameter values for the identified parameters are extracted with reference to an order definition file (see, for example, FIG. 6). Then, the priority order determination unit 235 can determine the priority order between the first control function and the second control function based on the extracted parameter value. When the parameter specified by the parameter specifying information is, for example, the parameter X in FIG. 6, the priority order determination unit 235 determines that “the priority order of the control function B is higher than the priority order of the control function A”. Focusing on the parameter value of the parameter X in FIG. 6 is because “control function A (X value: 4) <control function B (X value: 5)”.

  The priority order determination unit 235 outputs information representing the determination result of the priority order thus performed to the execution information generation unit 236 and the control function execution unit 240.

  The execution information generation unit 236 generates control function execution information based on information representing the priority determination result input by the priority determination unit 235. The control function execution information generated by the execution information generation unit 236 is information indicating that the control functions are executed in order from the control function with the higher priority to the control function with the lower priority. For example, when it is determined that “the priority order of the control function A is higher than the priority order of the control function B”, the execution information generation unit 236 executes the control function A having a higher priority and then lowers the priority. Control function execution information for executing the control function B is generated. The execution information generation unit 236 outputs the generated control function execution information to the control function execution unit 240.

  Based on the control function execution information input from the execution information generation unit 236, the control function execution unit 240 causes the mobile terminal 10 to execute the control function described in the control function execution information. At this time, if it is determined that the priority of the control function to be executed is higher than the priority of the control function currently being controlled by the mobile terminal 10, the control function executing unit 240 performs the current control by the mobile terminal 10. The mobile terminal 10 is caused to execute the control function to be executed after forcibly terminating the control function in the middle. Here, the priority between the control function to be executed and the control function currently being controlled by the mobile terminal 10 is determined based on the information indicating the priority determination result input by the priority determination unit 235. Can.

  On the other hand, if it is determined that the priority of the control function to be executed is not higher than the priority of the control function currently being controlled, the control function executing unit 240 determines that the control function currently being controlled by the mobile terminal 10 After waiting for the termination, the portable terminal 10 is caused to execute the control function to be executed. In this case, the control function execution unit 240 can determine the execution time of the control function to be executed by receiving, for example, information from the portable terminal 10 that the control function currently being controlled has been completed. Note that the priority order between the control function to be executed and the control function currently being controlled by the mobile terminal 10 is determined by the priority determination unit 235 described above, and the control function execution unit 240 inputs the determination result. It doesn't matter if you do.

  The control function execution unit 240 can cause the mobile terminal 10 to execute the control function to be executed by transmitting the control function execution information input from the execution information generation unit 236 to the mobile terminal 10. At this time, the control function execution unit 240 also transmits to the portable terminal 10 a signal indicating whether to forcibly terminate the currently controlled control function or to wait for the currently controlled control function to be terminated.

  The control function execution unit 240 is a generic name for the control function A execution unit 241, the control function B execution unit 242, the control function C execution unit 243, the control function D execution unit 244, and the like shown in FIG. The control function execution unit 240 may be provided according to the number of functions installed in the mobile terminal 10. 3 and 4, for example, the control function A execution unit 241 may correspond to the camera function unit 131 of the mobile terminal 10, and the control function B execution unit 242 may correspond to the external memory function unit 132 of the mobile terminal 10. The control function C execution unit 243 may correspond to the USB function unit 133 of the mobile terminal 10, and the control function D execution unit 244 corresponds to the voice call function unit 134 of the mobile terminal 10. May be.

  For example, when the control function execution information indicating that the control function A having a higher priority is to be executed first is input from the execution information generation unit 236, the control function A execution unit 241 sends the control function execution information to the mobile terminal 10. By transmitting to the camera function unit 131, the control function A can be executed by the mobile terminal 10. In this case, the control function A is a function for invalidating the camera function of the mobile terminal 10, for example. The control function A executing unit 241 can specify the mobile terminal 10 based on the mobile terminal specifying information input from the receiving unit 232.

  Further, for example, when control function execution information for executing the control function B having a higher priority is input from the execution information generation unit 236, the control function B execution unit 242 transmits the control function execution information to the mobile terminal 10 By transmitting to the external memory function unit 132, the control function B can be executed by the portable terminal 10. In this case, the control function B is a function that erases and resets all records in the external memory of the mobile terminal 10, for example. Note that the control function B execution unit 242 can specify the mobile terminal 10 based on the mobile terminal specifying information input from the reception unit 232.

(Configuration of instruction terminal 30)
Next, the instruction terminal 30 will be described. The instruction terminal 30 shown in FIG. 1 generates a command that becomes a source when the terminal control server 20 remotely controls the functions mounted on the mobile terminal 10 and supplies the generated command to the terminal control server 20.

The receiving unit 321 can input information regarding whether the employee is currently in the company or outside the company, for example, in conjunction with the employee entry / exit management system (Felica). The receiving unit 321 may input employee position information from a predetermined GPS-based external device. In addition, the reception unit 321 may input information indicating the current time or information indicating the day of the week using a clock function installed in the instruction terminal 30. Further, the receiving unit 321 may input the instruction information itself from another mobile terminal. For example, instruction information for remotely controlling the function of the grandfather's mobile terminal, which is not good at operating the mobile terminal, may be input from the child's mobile terminal. The receiving unit 321 may input instruction information from a predetermined device installed in a theater, a movie theater, a train, or the like. The receiving unit 321 may input necessary information by, for example, user input.

  The information received by the receiving unit 321 by the method as described above may include parameter specifying information for specifying a parameter used when the priority order of the terminal control server 20 is determined. Further, the parameter specifying information may specify a plurality of parameters depending on circumstances, and may further include giving priority to one of the plurality of parameters.

  The generation unit 322 generates instruction information based on information input from the reception unit 321. For example, when the information indicating that the employee is in the office is input from the receiving unit 321 even after the working time has passed, the generation unit 322 may include a camera function, an external memory function, Instruction information for stopping the USB function or the like may be generated. For example, when the information indicating that the user of the mobile terminal 10 is currently in a theater, a movie theater, a train, or the like is input from the reception unit 321, the generation unit 322 activates the voice call function of the mobile terminal 10. You may make it produce | generate the instruction information to the effect of stopping. In addition, when the parameter input information is included in the information input from the reception unit 321, the generation unit 322 generates the instruction information by including the parameter specification information. In addition, the generation unit 322 may generate instruction information for starting an arbitrary application remotely, or may generate instruction information for collecting a network log remotely. The generation unit 322 outputs the information generated in this way to the transmission unit 323.

  Each operation of the reception unit 321 and the generation unit 322 described above is merely an example of an operation of the reception unit 321 or the generation unit 322, and various further scenes can be considered depending on an actual situation.

  The transmission unit 323 transmits the instruction information input from the generation unit 322 to the terminal control server 20 through the communication unit 310. The receiving unit 232 of the terminal control server 20 described above receives using this instruction information.

  In order to grasp step S4, the terminal state confirmation unit 233 of the terminal control server 20 first requests the portable terminal 10 to notify the control function currently under control (step S401). Next, the terminal state confirmation unit 233 receives a response to the notification request in step S401. When there is a control function currently being controlled in the mobile terminal 10, current control function specifying information for specifying the control function is transmitted to the terminal state confirmation unit 233 as the response. On the other hand, if there is no control function currently being controlled in the mobile terminal 10, information indicating that is transmitted to the terminal status confirmation unit 233 as the response (step S402).

  Next, a control function to be executed by the mobile terminal 10 is specified. This operation can be performed when the specific information generation unit 234 of the terminal control server 20 generates control function specific information. The specific information generation unit 234 can directly use the control function specifying information included in the instruction information received in step S3 as one or a plurality of control function specifying information. In addition, when the terminal state confirmation unit 233 receives the current control function specification information in step S402, the specific information generation unit 234 sets the current control function specification information as one or more other control function specification information. (Step S5, specific information generation step).

  Next, the priority order among the plurality of control functions specified in step S5 is determined.
