Description

  The present invention relates to a communication device that is connected to a communication line and has a function of communicating with another communication device.

  In recent years, communication devices (such as portable terminals and smartphones) having various functions have become widespread and have been used in various service fields (see Patent Document 1). For example, in the field of crime prevention services such as facilities and mansions, if a security guard is in possession of a communication device, a monitoring sensor or camera installed in the facility or mansion will report an abnormality to the monitoring center. The monitoring center sends a “handling” instruction to the security guard (the communication device possessed by the security guard). The guards deal with anomalies (intrusion of suspicious persons, fires, etc.) that occurred in the facility or mansion while communicating and coordinating with the monitoring center using the communication device.

JP 2008-227907 A

  However, when communication devices are used in the field of crime prevention services, information handled by security guards using communication devices when dealing with anomalies that occur in facilities or mansions is information that should be kept secret from business. It is often necessary to prevent the information from leaking to a third party. Also, it is necessary to prohibit the security guard from privately using (unauthorized use) the communication device for purposes other than business.

  The present invention has been made in view of the above-described problems, and provides a communication device that can prohibit unauthorized use of the communication device other than business and can prevent information leakage from the communication device. Objective.

  A communication terminal of the present invention is a communication device that is connected to a communication line and communicates with another communication device, a receiving unit that receives business instruction information from a specific communication device, and the received instruction information A display unit for displaying; an operation unit for performing user input; and a mode setting unit for setting a restriction mode in which information transmission based on the user input is restricted, or a release mode in which the restriction on information transmission is released. The mode setting unit changes the setting from the restriction mode to the release mode when receiving the instruction information when the restriction mode is set.

  According to the present invention, when a restriction mode is set in a communication device (for example, possessed by a guard or the like), information transmission based on user input is restricted. When the restriction mode is set on the communication device, business instruction information from a specific communication device (for example, a communication device installed in a monitoring center or a communication device owned by a person in charge of business) Is received, the setting is changed from the restriction mode to the release mode, and the restriction on information transmission is released. As a result, information transmission is restricted when no business instruction is received, so that unauthorized use of the communication device other than business can be prohibited, and information leakage can be prevented.

  In addition, the communication terminal of the present invention includes a transmission unit that transmits a response end signal to the specific communication device when a user input for response end is performed from the operation unit, and the mode setting unit has the release mode set to If the coping end signal is transmitted when it is set, the setting may be changed from the release mode to the restriction mode.

  For example, when a countermeasure end user input is made from the operation unit of the communication device, for example, when the countermeasure is completed by a security guard, a countermeasure end signal is transmitted to the specific communication device. Thereby, it is possible to know that the countermeasure has been completed in another communication device. In the communication device, the setting is changed to an appropriate mode (control mode). For this reason, information transmission can be restricted when the requirements for business instructions are completed.

  In the communication terminal of the present invention, the mode setting unit changes the setting from the cancellation mode to the restriction mode when receiving a countermeasure end signal from the specific communication device when the cancellation mode is set. May be.

  For example, when the monitoring staff determines that the handling is finished at the monitoring center where the specific communication device is installed, a handling end signal is transmitted from the specific communication device to the communication terminal. When the communication device receives the countermeasure end signal, the setting is changed to an appropriate mode (control mode). For this reason, information transmission can be restricted when the requirements for business instructions are completed.

  In the communication terminal of the present invention, in the restriction mode, outgoing calls and electronic mails are restricted, and incoming calls and electronic mails may not be restricted.

  In the restricted mode, outgoing calls and emails are restricted, so that unauthorized use other than business of the communication device can be prohibited, and information leakage can be prevented. However, in the restricted mode, incoming calls and mails are not restricted. Therefore, for example, it is possible to receive an emergency contact by telephone or mail from a monitoring center or the like.

  The communication terminal of the present invention may further include a transmission unit that transmits current position information to the specific communication device when the release mode is set.

  When the release mode is set, the current position information of the communication device is transmitted to the specific communication device, so the security terminal possessing the communication terminal (the monitoring center in which the specific communication device is installed) ) Can be grasped.

  The communication device of the present invention includes an operation unit that performs an operation for inputting current handling status information, and a transmission unit that transmits the input current handling status information to the specific communication device. You may prepare.

  When the current handling status information is input while the release mode is set, the information (current handling status information) is transmitted to a specific communication device. Thereby, it is possible to grasp the current coping status of the communication device (the monitoring person who owns it) at a specific communication device (such as a monitoring center where the communication device is installed).

  The method of the present invention is a method executed by a communication device that is connected to a communication line and communicates with another communication device. In the communication device, when business instruction information is received from a specific communication device, The received instruction information is displayed, a restriction mode in which information transmission based on user input is restricted, or a release mode in which the restriction on information transmission is released is set, and the method is set with the restriction mode being set. When the instruction information is received while the user is in the setting mode, the setting is changed from the restriction mode to the release mode.

  The program of the present invention is a program that is executed by a computer provided in a communication device that is connected to a communication line and communicates with another communication device. When the instruction information is received, the received instruction information is displayed, a restriction mode in which information transmission based on user input is restricted or a release mode in which the restriction on information transmission is released is set, and the program When the instruction information is received when the restriction mode is set, the computer is caused to execute a process of changing the setting from the restriction mode to the release mode.

  Also in these methods and programs, similarly to the communication device described above, when the restriction mode is set in the communication device (for example, possessed by a guard), information transmission based on the user input is restricted. When the restriction mode is set on the communication device, business instruction information from a specific communication device (for example, a communication device installed in a monitoring center or a communication device owned by a person in charge of business) Is received, the setting is changed from the restriction mode to the release mode, and the restriction on information transmission is released. As a result, unauthorized use of the communication device other than business can be prohibited, and information leakage can be prevented.

  According to the present invention, it is possible to prohibit unauthorized use of a communication device other than business, and to prevent information leakage from the communication device.

Instruction information) is output to the control unit 3. The communication protocol for the communication line NW is not described because a known technique may be used.

  The touch panel 4 is an interface for displaying information to the security guard P and allowing the security guard P to input predetermined information, and includes a display unit 9 and an operation unit 10. The display unit 9 is a display area formed on the touch panel in order to display information on the guard P. In the display area, for example, the above instruction information is displayed. The operation unit 10 is an operation area such as a keyboard and buttons formed on the touch panel for the guard P to input.

  The storage unit 11 includes various applications for controlling the operation of the communication device 1, an operating system, ROM / RAM that stores security guard registration data, and the like. Information is read or written in the storage unit 11 by the control unit 3. In particular, the storage unit 11 includes a mode storage area 111, a setting storage area 112, a contact storage area 113, and the like as storage areas.

  The mode storage area 111 is an area for storing whether or not the operation of the communication apparatus 1 is restricted, that is, stores one of a restriction mode and a release mode.

  Here, the restriction mode is a mode in which information transmission based on the input of the guard P is restricted, and is a mode set when the guard P is not dealing with the monitoring target. In the restricted mode, outgoing calls and emails are restricted, and incoming calls and emails are not restricted. Even in the restricted mode, it is possible to place a call to a specific party (phone number or mail address set in advance) or an emergency special phone number (110, 118, 119, etc.) Sending email is not restricted. On the other hand, the release mode is a mode in which the restriction on information transmission based on the input of the guard P is released, and is set when the guard P is dealing with the monitoring target.

  The setting storage area 112 stores setting information of the communication device 1. The control unit 3 controls the communication device 1 based on the setting information. The setting information includes settings related to display and operation regarding the application of the communication apparatus 1, settings related to the operation unit 10, and the like.

  The contact address storage area 113 stores information on contact information of a person or an organization (for example, each security guard P, a person responsible for the job, the monitoring center C, etc.) who may be contacted in the job. The contact storage area 113 stores the name of the person or the name of the institution, the telephone number, and the mail address in association with each other. Further, even in the restriction mode described above, it is stored in the contact storage area 113 so that a contact that does not restrict outgoing calls and mails can be identified.

  The control unit 3 includes a microcomputer including a CPU, a ROM, a RAM, and the like and peripheral circuits thereof, and controls each unit of the communication device 1 described above. The control unit 3 includes, as a functional module realized by the microcomputer and a computer program executed on the microcomputer, a communication control unit 31 that transmits and receives information to and from the outside using the communication unit 2, and a general mobile phone. A call management unit 32 as an application that implements a call function installed in a telephone or a smartphone, and a mail management unit 33 as an application that implements an e-mail client function installed in a general mobile phone or smartphone. And a restriction unit 34 for changing the setting of the restriction mode or the release mode.

  The communication control unit 31 manages information transmission to an external device by controlling the communication unit 2. Further, the communication control unit 31 transmits information output from the communication unit 2 to each unit in the control unit 3.

  Specifically, regarding the call processing, when the communication control unit 31 receives from the call management unit 32 a call call request that is a signal requesting a call specifying a call destination, the call control process to the call destination is performed. Is executed by the communication unit 2.

  When the communication control unit 31 receives a call incoming signal for requesting a call from an external device via the communication unit 2, the communication control unit 31 notifies a call incoming notification that there is an incoming call from the external device. To do. When the communication control unit 31 receives a response signal for instructing a response to the incoming call notification from the call management unit 32, the communication control unit 31 causes the communication unit 2 to execute a response process for the incoming signal, and makes a call with an external device. Establish state.

  Further, when receiving a call end request for ending the call state from the call management unit 32, the communication control unit 31 causes the communication unit 2 to execute a call end process for ending the call state.

  When the communication control unit 31 receives a mail transmission request, which is a signal for requesting transmission of an e-mail designating a destination mail address, from the mail management unit 33, the communication control unit 31 sends the e-mail transmission / reception process to the transmission destination. Causes the communication unit 2 to execute transmission processing.

  When the communication control unit 31 receives a mail reception signal indicating that an e-mail addressed to itself has newly entered from the external device via the communication unit 2, the mail indicating that there is a mail from the external device. A reception notification is sent to the mail management unit 33.

  The call management unit 32 causes the display unit 9 and the operation unit 10 to display the call function. Here, in the present embodiment, in the setting storage area 112 described above, it is normally set to prohibit display on the display unit 9 and the operation unit 10 from displaying the call management unit 32 regarding the outgoing call. . For this reason, the security guard P cannot make a call by operating the operation unit 10 originally displayed by the call management unit 32. In order to prohibit display related to outgoing calls, for example, even if an icon for starting the call management unit 32 is operated by the security guard P, the operation is invalidated, or the icon itself is displayed. An appropriate method may be used such as preventing display.

  On the other hand, when the call management unit 32 receives from the restriction unit 34 the call transmission information for requesting the transmission of the call specifying the destination, the call management unit 32 issues a call transmission request to the communication control unit 31. As described above, in the present embodiment, the function related to the outgoing call of the call management unit 32 mounted on a general mobile phone or smartphone is restricted, while the outgoing call based on the input from the restriction unit 34 is made. Is allowed.

  Further, since the display related to the incoming call by the call management unit 32 is not prohibited, the guard P can perform an operation related to the incoming call using the screen displayed by the call management unit 32. Specifically, when receiving a call incoming notification from the communication control unit 31, the call management unit 32 displays that the incoming call is received along with the caller information on the display unit 9, and displays a response button on the operation unit 10. indicate. In addition, when the response button of the operation unit 10 is operated by the guard P, the call management unit 32 sends a response signal to the communication control unit 31. Furthermore, the call management unit 32 displays an end button on the operation unit 10 while the call state is established. When the end button is operated by the security guard P, the call management unit 32 sends an end request.

  The mail management unit 33 causes the display unit 9 and the operation unit 10 to display the electronic mail client function. Here, in the present embodiment, in the setting storage area 112 described above, it is prohibited to display a keyboard on the operation unit 10, and an application for managing a contact address mounted on a general mobile phone or smartphone is provided. It is prohibited to operate. For this reason, the guard P cannot operate the operation unit 10 to transmit mail under the restriction of the mail management unit 33.

  On the other hand, when the mail management unit 33 receives mail transmission information for requesting transmission of an email specifying a mail address from the restriction unit 34, the mail management unit 33 issues a mail transmission request to the communication control unit 31. As described above, in the present embodiment, the function related to the transmission of the mail of the mail management unit 33 mounted on a general mobile phone or smartphone is restricted, while the transmission of the mail based on the input from the restriction unit 34 is performed. Is allowed.

  In the mail management unit 33, there are no restrictions on displays other than the keyboard display (for example, operation button display). For this reason, the guard P can operate the operation unit 10 to display the screen by the mail management unit 33 on the display unit 9 and view the contents of the email received from the external device. Specifically, when the mail management unit 33 receives a mail reception notification from the communication control unit 31, the mail management unit 33 displays on the display unit 9 that the mail has been received together with the information on the transmission source, and communicates with the communication control unit 31 and the communication. An electronic mail is received from an appropriate mail server via the unit 2. The mail management unit 33 displays the management screen for managing the received electronic mail and the content of the electronic mail according to the operation of the operation unit 10 by the guard P.

  In this embodiment, an e-mail is used as business instruction information, and the body of the e-mail as the business instruction information includes countermeasure information including an address to be monitored, abnormal contents, and a restriction mode. Contains a hyperlink to change from to release mode. Further, the hyperlink includes a command for starting the restriction unit 34 and a code that is information to be passed to the restriction unit 34. For this reason, when the guard P operates the hyperlink, the restriction unit 34 is activated and a code is input to the restriction unit 34 to perform processing for changing from the restriction mode to the release mode. That is, in the present embodiment, a command that can be executed by the input of the guard P is added to the instruction information, and whether or not the information received from the center device is the instruction information by executing this command. It is a mechanism to judge.

  The restriction unit 34 includes a mode setting unit 341, an information transmission unit 342, and a countermeasure management unit 343.

  The mode setting unit 341 sets two modes (restriction mode and release mode). Specifically, the mode setting unit 341 determines whether or not the code input when the above-described hyperlink is operated by the security guard P is a code that has already been input before. When the mode setting unit 341 determines that the code is not input before, the mode setting unit 341 stores the release mode in the mode storage area 111. The code input to the mode setting unit 341 is sequentially stored in the storage unit 11, and the mode setting unit 341 refers to the code stored in the storage unit 11 so that the code input this time is It is determined whether or not the code has already been input. If the mode setting unit 341 determines that the code has been input before, the mode setting unit 341 does not change the setting to the release mode by the hyperlink described above. As a result, the security guard P is restricted so that it can only be changed a predetermined number of times (in the above example, once) from the same hyperlink to the release mode.

  In addition, when the mode setting unit 341 receives from the handling management unit 343 a handling end notification indicating that handling has ended, the mode setting unit 341 stores the restriction mode in the mode storage area 111.

  When an operation for transmitting information is performed by the security guard P, the information transmission unit 342 causes the touch panel 4 to display an information transmission screen necessary for the operation. The security guard P can refer to the contact information stored in the contact information storage area 113 from this information transmission screen. In the present embodiment, in the setting storage area 112 described above, the keyboard display is permitted for the operation on the restriction unit 34. For this reason, the security guard P can input the content of the text of an email from the information transmission screen.

  The information transmission unit 342 refers to the mode storage area 111 when a transmission operation for transmitting information is performed by the security guard P, and does not accept the transmission operation when the restriction mode is stored, and cancels the mode. Is stored, the transmission operation is accepted. However, even when the restriction mode is stored, if the transmission operation is for a contact that does not restrict outgoing calls or mails, the transmission operation is accepted.

  When the transmission operation is accepted, if the transmission operation is a call transmission, the information transmission unit 342 sends the call transmission information to the call management unit 32. If the transmission operation is an email transmission, the information transmission unit 342 transmits a mail. Information is sent to the mail manager 33.

  The countermeasure management unit 343 displays an input window for the guard P to input the current countermeasure status information using the touch panel 4. The coping status includes “coping start”, “coping”, “coping end”, “standby”, and the like. “Correction start” is a status indicating a state in which the guard P confirms the instruction information and leaves for the monitoring target in which an abnormality has occurred. “Handling” is a status indicating that the security guard P has arrived at the monitoring target in which an abnormality has occurred and has started to handle the monitoring target abnormality. “End of coping” is a status indicating that the guard P has finished coping with the abnormality of the monitoring target and has started returning from the monitoring target to a predetermined waiting place. “Waiting” is a status indicating that the guard P is waiting at a predetermined waiting place.

  The handling management unit 343 performs processing for transmitting the input current handling status information to the monitoring center C. Specifically, the e-mail transmission information designating the e-mail address of the monitoring center C and designating the handling status information in the e-mail body is sent to the e-mail management unit 33. As described above, in this embodiment, the mail management unit 33 allows mail transmission based on the input from the restriction unit 34 regardless of whether the mode is the restriction mode or the release mode. Thereby, the handling status information input by the guard P is transmitted to the monitoring center C. When the center device of the monitoring center C receives the handling status information, it notifies the monitoring staff of this fact. Therefore, the monitoring staff at the monitoring center C can grasp the status of the security guard P's response.

  Further, when the guard P inputs “end of handling” from the operation unit 10, the handling management unit 343 notifies the mode setting unit 341 of the handling end. Thereby, the mode setting unit 341 changes the setting from the release mode to the restriction mode when a countermeasure end signal is transmitted to the monitoring center C. Accordingly, the communication device 1 can change the setting to an appropriate mode (restricted mode) in conjunction with the report of the end of the countermeasure that the security guard P needs to perform for business.

  Further, when the release mode is stored with reference to the mode storage area 111, the countermeasure management unit 343 causes the positioning unit 13 to acquire the current position information and transmits the acquired current position information to the monitoring center C. . In this transmission process, mail transmission information that designates the mail address of the monitoring center C and designates the position information calculated in the e-mail body is sent to the mail management unit 33. Thereby, the current position of the guard P is transmitted to the monitoring center C. When the center device of the monitoring center C receives the position information, it notifies the monitoring staff of this fact. Therefore, the monitor of the monitoring center C can grasp the current position of the guard P. Note that acquisition and transmission of the current position information may be performed periodically (for example, every minute).

  The main operation of the communication apparatus 1 configured as described above will be described with reference to the flowchart of FIG. In addition, this flow is executed by the above-described control unit 3 every predetermined time (for example, every minute) using each unit.

  As shown in FIG. 3, in the communication device 1 according to the present embodiment, as an initial setting (default setting), a restriction mode is stored in the mode storage area 111, and information transmission based on the input of the guard P (for example, (Sending calls and sending e-mails) is restricted (S1). When the receiving unit 6 receives business instruction information from the monitoring center C (S2), the mail management unit 33 displays the received instruction information on the display unit 9 (S3). When the hyperlink is operated by the security guard P in the displayed instruction information, the mode setting unit 341 changes the setting from the restriction mode to the release mode, thereby releasing the restriction on the information transmission based on the input of the security guard P. (S4).

  When the release mode is set, the handling management unit 343 transmits the current position information of the communication device 1 to the monitoring center C (S5), and an input window for inputting the current handling status information to the display unit 9 Is displayed (S6). When current handling status information is input from the operation unit 10 (S7), the handling management unit 343 transmits the input current handling status information to the monitoring center C (S8). The security guard P inputs “handling”, “handling” and the handling status in accordance with the progress of the instructed handling. Then, the control unit 3 repeats the processing of steps S5 to S9 until there is an input of “end of handling”.

  When “handling of countermeasure” is input by the guard P as the current countermeasure status (S9), the countermeasure manager 343 transmits a countermeasure end signal to the monitoring center C via the transmitter 5 (S10). And the mode setting part 341 changes a setting from cancellation | release mode to restriction | limiting mode, and the information transmission (for example, transmission of a call and transmission of an email) based on the input of the guard P is restrict | limited (S11).

  According to such a communication apparatus 1 of the present embodiment, unauthorized use other than business of the communication apparatus 1 can be prohibited, and information leakage from the communication apparatus 1 can be prevented.

  That is, in the present embodiment, when the restriction mode is set in the communication device 1 (for example, possessed by the guard P), information transmission based on the input of the guard P is restricted. When the restriction mode is set in the communication device 1 and business instruction information is received from the center device, the setting is changed from the restriction mode to the release mode, and the restriction on information transmission is released. As a result, unauthorized use of the communication device 1 other than business can be prohibited, and information leakage can be prevented.

  For example, when a countermeasure end user input is made from the operation unit 10 of the communication apparatus 1 when a countermeasure by the security guard P is completed, a countermeasure end signal is transmitted to the center apparatus. Thereby, the supervisor can know that the countermeasure has been completed at the center device (monitoring center C where the center device is installed). In the communication device 1, the setting is changed to an appropriate mode (restriction mode).

  In the present embodiment, since outgoing calls and e-mails are restricted in the restricted mode, unauthorized use other than business of the communication device 1 can be prohibited and information leakage can be prevented. . However, in the restricted mode, incoming calls and emails are not restricted. Therefore, for example, it is possible to receive an emergency contact by telephone or electronic mail from the monitoring center C or the like.

  In the present embodiment, when the release mode is set, the current position information of the communication device 1 is transmitted to the center device, so that the monitor is the center device (the monitoring center C where the communication device 1 is installed). It is possible to grasp the current position of the communication device 1 (the guard P who owns the communication device 1).
