Description

  The present invention relates to a portable mobile communication device.

  Recently, mobile communication devices typified by mobile phones and PHS (Personal Handy Phone System) have become widespread and have become one of the items closely related to daily life. The mobile communication device is provided with a function for registering a telephone number and an e-mail address of a communication destination, and the mobile communication device is used as a telephone book, an address book, a memo pad, etc. by using this function. This is because they are often used instead.

  Since the mobile communication device can be carried and used outdoors, the possibility of theft or loss is often high. For example, if it is used by a theft, the usage fee will be charged by the operator. For this reason, in the mobile communication device, a key lock function for locking / unlocking by inputting a personal identification number or the like is set in order to prevent use by others even in the event of theft.

  There are other reasons why the key lock function is set in this way. In mobile communication devices, if an operation to respond to an incoming call is performed, a call can be made by anyone other than the owner. Therefore, if there is an incoming call when the owner is absent, This is because privacy is not protected.

  Therefore, in order to prevent leakage of the privacy information of the owner, various mobile communication devices that prohibit calls other than the owner when an incoming call is made have been proposed.

  For example, in the mobile communication device proposed in Patent Document 1, a response operation procedure for an incoming call can be registered in advance by a key input operation. If the response operation procedure is not registered at the time of an incoming call, the communication mode is immediately set by the communication start instruction. On the other hand, when there is a registration of a response operation procedure at the time of an incoming call, the call mode is set on condition that the operation procedure for responding to the incoming call matches the registered operation procedure.

  In the mobile communication device according to Patent Document 1, it is determined whether or not a specific operation that only the user (owner) can know at the time of the incoming call (during a call) has been performed, so However, considering the situation where the user himself / herself does not carry the mobile communication device, such as when going out for a meeting while the mobile communication device is placed on the desk, It is also necessary to prevent an unauthorized operation by a user other than the incoming call (that is, an unauthorized operation at the time of outgoing call).

  As a typical example of a mobile communication device that prevents an unauthorized operation at the time of calling, one proposed in Patent Document 2 can be cited.

  The mobile communication device proposed in Patent Document 2 includes a storage device such as a telephone directory memory for storing data such as a telephone number related to a specific communication device. When there is a communication instruction, it is checked whether or not the data related to the call destination that has been instructed to communication is registered in the storage device. If the call destination data is not registered, it is prevented from being called by the key lock control. It has become.

  By the way, as operation modes for making a call from a mobile communication device to a specific communication device, (1) a mode for making a call by directly inputting a telephone number, and (2) selecting a party to call from a telephone directory data or the like There are many modes such as a mode of making a call by designating and (3) a mode of making a call by selecting and designating a party to call from the incoming call history data and outgoing call history data.

  In recent mobile communication devices, there are many models in which a secret function is set so that data registered in the device cannot be referred to unless a predetermined authentication code such as a password is input. However, there are few users who remember all the phone numbers that can be called. Rather, many users specify the phone numbers that are frequently called from the phone book data without directly entering them, and the authentication code. Actually, there are few opportunities for users to use the secret function due to the troublesome input.

  In general, secret data is not displayed at all (in secret data non-display mode) at all, and of course, only number display is available for incoming calls from secret-registered communication devices. The name is not displayed. The same applies to the incoming call history. Usually, a portable mobile communication device is carried around in a normal mode (secret data non-display mode) from the viewpoint of loss or theft. However, as described above, an incoming call from the owner's communication device that has a secret registration such as a close friend / acquaintance is only displayed as a number. If this is one or two, it is possible to memorize it, but it is generally difficult to identify the individual from the displayed number. In addition, even if an incoming call is received from a communication device of a person who has registered secret, there are not a few users who feel uncomfortable in answering without specifying the sender. It is necessary to ask such a user such as “Who?” Regardless of who is close, and based on this response, it is determined that the call is received from the communication device of the person who registered secretly. Switching to the secret display mode has a problem that the operation is not in time. Therefore, always carrying around in the secret display mode may lose the significance of the secret function.

  Under such circumstances, the technique disclosed in Patent Document 2 provides a communication instruction to a communication destination that is not included in communication history data such as incoming history data and outgoing history data, or registration data such as telephone directory data. In such a case, the communication instruction is invalidated and a key lock is set so that a call cannot be made, thereby preventing misuse of others and improving security.

  However, with the technique described in Patent Document 2, even when the user is the owner, if a call is made to a number other than a previously registered and stored number, the call instruction becomes invalid and the key lock is applied. Therefore, even if the user is the owner himself / herself, when making a call to an unregistered number, the telephone number to be transmitted must be registered in advance, which may be inconvenient in using the mobile communication device. is there.

  The present invention has been made in view of the above technical problem, and can prevent leakage of personal information associated with unauthorized use without invalidating a call instruction or applying a key lock. An object of the present invention is to provide a mobile communication device with high performance.

When the communication start instruction is determined, the authentication information input by the information input means within a predetermined time after the communication start instruction is compared with the authentication information stored in the authentication information storage means, and As a result, on the condition that the authentication information input is authenticated, additional information associated with the communication information for which the communication start instruction is given is displayed on the display of the transmission information including the communication destination information for which the display means has been instructed to start the display. And a control means for executing a second display process for changing to display of outgoing information including.

  Here, the “additional information” is a concept including personal information such as the name of the communication partner.

  In the above configuration, when a communication start instruction is given to another communication device, it is determined whether or not it is a communication start instruction to a predetermined communication destination registered as data, and the determination result is the predetermined When it is determined that it is a communication start instruction to the communication destination, the transmission information including the communication destination information of the predetermined communication destination in which the data is stored is displayed. As described above, when it is determined that the communication start instruction is a communication start instruction to a predetermined communication destination with which data has been registered, authentication information input within a predetermined time after the communication start instruction is stored. The authentication information is compared. At this time, a message prompting a request for authentication information input such as “Please input authentication information” or a voice output is not made. As a result of the authentication determination, when both are matched and authentication information input is authenticated, the display of the transmission information including the communication destination information for which the communication start instruction has been issued is associated with the communication information for which the communication start instruction has been issued. The display is changed to display outgoing information including the added additional information (name, etc.).

  In the mobile communication device, the control means executes a process of performing a communication start control with a predetermined communication destination when authentication information input is authenticated in the second display process.

  As described above, since the communication start control with the predetermined communication destination is performed only when the authentication information input is authenticated in the second display process, unauthorized use can be reliably prevented.

  The mobile communication device according to the second aspect of the present invention is a portable mobile communication device, and data storage means for storing data including communication destination information for uniquely specifying a communication destination capable of communication; A communication start instruction means for instructing the start of communication with another communication apparatus, a display means for displaying information related to communication, an information input means for inputting various information, and a user Triggered by an authentication information storage means for storing authentication information for authenticating whether or not there is an authority to instruct communication start, and when a communication start instruction is given to another communication device by the communication start instruction means A first process for displaying on the display means the transmission information including the communication destination that has been instructed to start communication, and determining whether or not the communication start instruction is for a predetermined communication destination registered in the data storage means; And in the first process If the communication start instruction is determined to be a communication start instruction to a predetermined communication destination, the authentication information input by the information input means and the authentication information storage means are stored within a predetermined time after the communication start instruction. Control means for executing a second process for performing communication start control with a predetermined communication destination on the condition that the authentication information input is compared and, as a result, the authentication information input is authenticated. It is equipped with.

  In the above configuration, when a communication start instruction is given to another communication device, the transmission information including the communication destination that has received the communication start instruction is displayed, and the communication start instruction is registered. It is determined whether or not it is a communication start instruction to a predetermined communication destination. When it is determined that the communication start instruction is a communication start instruction to a predetermined communication destination, the authentication information input within a predetermined time after the communication start instruction is compared with the stored authentication information. Is called. As a result of the comparison, when both are matched and authentication information input is authenticated, communication start control with a predetermined communication destination is performed.

  By the way, the present invention is intended to prevent unauthorized use by a third party. Therefore, for example, a request for inputting authentication information such as “please input authentication information” is specified. It is not possible to issue a message that promptly appeals to the visual and / or auditory sense of a third party.

  Therefore, in the above mobile communication device, the control means relates to the display of the transmission information executed in the first process, and the process of changing the display mode when the authentication information input is authenticated in the second process. Execute.

  Here, as a change mode of the display of the transmission information, a mode of displaying personal information such as the name of the communication partner can be exemplified.

  As described above, it is a control for the original user that only the display mode is changed without issuing a message for specifically requesting the authentication information input.

  According to the present invention, it is possible to prevent leakage of personal information due to unauthorized use without invalidating the transmission instruction or applying a key lock. As a result, the mobile communication device has higher security.

The mobile communication device 100 displays a screen as if making a call when a call instruction to a specific telephone number is given. Only when a specific operation is performed within a predetermined time, it is programmed to change the screen display mode and perform actual transmission start control.

  FIG. 5 is a flowchart showing a control flow of a main routine related to a program for realizing the function of the mobile communication device 100. In the mobile communication device 100, when the power is turned on from the power-off state, the secret data automatically enters the non-display mode.

  Referring to FIG. 5, in the mobile communication device 100, when a power-on operation is performed by the call button 110, the control unit 130 first assigns “0” to the temporary variable SMD to hide the secret data. (Step S100). The variable SMD “0” is temporarily stored in the temporary memory area 132D of the memory device 132.

  And the control part 130 displays a standby screen on the display 120 (step S200), and then advances control to step S300, S400, S500, S600, and S700.

  When the control proceeds to steps S300 to S700, the control unit 130 makes an incoming call, a call button 110 call operation, a secret button 112 operation, a phone book registration button 114 operation, and a phone book list display button 116 display start operation. It is determined whether any of the following events have occurred. Control branches according to the determination result.

  If there is an incoming call (YES in step S300), control unit 130 performs incoming call control (step S800). This incoming call control will be described in detail later.

  When a call operation is performed with call button 110 (YES in step S400), control unit 130 performs call control (step S900). This call control will be described in detail later.

  When secret button 112 is operated (YES in step S500), control unit 130 performs secret mode change control (step S1000). This secret mode change control will be described later in detail.

  When operation of phone book registration button 114 is performed (YES in step S600), control unit 130 performs one entry entry control (step S1100). This one-phone book entry control will be described in detail later.

  When a display start operation is performed by telephone book list display button 116 (YES in step S700), control unit 130 performs telephone book list display control (step S1200). This telephone directory list display control will be described in detail later.

  When none of the above-described incoming calls, outgoing operation of the call button 110, operation of the secret button 112, operation of the phone book registration button 114, or display start operation of the phone book list display button 116 has occurred (step S300) -NO in S700), control unit 130 returns control to step S200 to display a standby screen.

  This series of control is repeatedly executed until the power off operation is performed by the call button 110.

(Incoming call control)
FIG. 6 is a flowchart showing a control flow of incoming call control (step S800 in FIG. 5), which is a subroutine related to a program for realizing the function of mobile communication device 100.

  In the incoming call control, first, the control unit 130 of the mobile communication device 100 displays a predetermined incoming call on the display 120 and starts an incoming call notification (steps S802 and S804). Examples of the incoming call notification mode include a mode in which vibration is generated by operating the vibration output device 144, a mode in which a bell sound is generated by operating the bell sound output device 146, and a mode in which these are combined. be able to.

  Then, the control unit 130 determines whether or not the call operation of the call button 110 is performed before a predetermined time elapses based on the timing output from the timer 134 (steps S806 and S808). Control branches according to the determination result.

  If a call receiving operation is performed with call button 110 within a predetermined time (NO in step S808 and YES in step S806), control unit 130 stops the incoming call notification (step S812). Thereafter, the control unit 130 performs telephone connection control such as off-hook and waits for the end of the call (steps S814 and S816). When the call ends (YES in step S816), control unit 130 returns control to step S200 shown in FIG. 5 and displays a standby screen. The control unit 130 determines that the call has ended, such as a call end operation of the call button 110 on the mobile communication device 100 side, reception of a call end signal from another communication device, and a connection error for a predetermined time. The state that the state where it cannot connect with another communication apparatus continues by can be mentioned.

  If the call button 110 is not received within a predetermined time (NO in step S806 and YES in step S808), control unit 130 stops the incoming call notification (step S810). Then, the control part 130 returns control to step S200 shown in FIG.

(Call control)
7 and 8 are flowcharts showing a control flow of call control (step S900 in FIG. 5) which is a subroutine related to a program for realizing the function of the mobile communication device 100.

  Referring to FIG. 7, in the calling control, first, control unit 130 of mobile communication apparatus 100 waits for a telephone number to be input by operating numeric keypad 108 (step S902). When the telephone number is input (YES in step S902), control unit 130 sets “input telephone number” as temporary variable Dno, “0” as temporary variable Dsec, and “NULL” as temporary variable Dname. Substitution is performed (step S904). These variables Dno “input telephone number”, Dsec “0”, and Dname “NULL” are temporarily stored in the temporary memory area 132 D of the memory device 132. Thereafter, the control unit 130 accesses the phone book data Adr [n] stored in the phone book memory area 132A of the memory device 132, and retrieves the input telephone number Dno from the phone book data Adr [n] ( Step S906). As a result of this search, if the input telephone number (hereinafter also referred to as “calling destination telephone number”) Dno is data registered in the telephone directory data (YES in step S908), the control unit 130 temporarily stores “Adr [i] .sec” is substituted for the variable Dsec and “Adr [i] .name” is substituted for the temporary variable Dname (step S910), and then the control proceeds to step S912. At this time, the variables Dsec “Adr [i] .sec” and Dname “Adr [i] .name” are temporarily stored in the temporary memory area 132D. If calling destination telephone number Dno is not registered in the telephone directory data (NO in step S908), control unit 130 causes control to jump to step S912.

  When the control proceeds to step S912, the control unit 130 determines whether or not the value of the temporary variable Dsec corresponding to the call destination telephone number Dno is “1”. Control branches according to the determination result. In addition, said determination is Adr [i]. This is accomplished by referring to the value of the sec variable.

  The value of the temporary variable Dsec is not “1”, that is, Adr [i]. When the value of the sec variable sec is “0”, or the input telephone number Dno is not registered in the phone book data Adr [n] and the value of the variable sec cannot be specified (NO in step S912), the control is performed. The unit 130 determines that the data is normal data, and determines whether the temporary variable Dname is “NULL” (step S918). The temporary variable Dname is “NULL”, that is, Adr [i]. If the name of the callee cannot be specified from the name (YES in step S918), control unit 130 adds callee telephone number Dno on display 120 to display a call instruction (step S920). Thereafter, the control unit 130 advances the control to step S922. The temporary variable Dname is not “NULL”, that is, Adr [i]. When the name of the callee can be identified from the name (NO in step S918), for example, as shown in FIG. 13, the control unit 130 gives the callee name Dname on the display 120 and displays a call instruction. (Step S924). Thereafter, control proceeds to step S922.

  In step S922, the control unit 130 operates the bell sound output device 146 to sound a ringing tone, and the control proceeds to step S938 shown in FIG.

  The value of the temporary variable Dsec is “1”, that is, Adr [i]. When the value of the sec variable “sec” is “1” (YES in step S912), the control unit 130 determines that the data is secret data, and as shown in FIG. The telephone number Dno is assigned to display a call instruction, and the bell sound output device 146 is activated to sound a ringing tone (steps S914 and S916). Thereafter, the control unit 130 advances the control to step S926 and step S928 shown in FIG.

  Referring to FIG. 8, when the control proceeds to steps S <b> 926 and S <b> 928 when the data related to the call destination is secret data, the control unit 130 elapses a predetermined time based on the time measurement output from the timer 134. It is determined whether or not a password has been input by operating the numeric keypad 108 until then. Control branches according to the determination result.

  When the password is input within the predetermined time (NO in step S928 and YES in step S926), control unit 130 matches the input password and the password stored in password memory area 132C of memory device 132. It is determined whether or not to perform (step S934). If both match and authentication of the input password is made (YES in step S934), the control unit 130 displays on the display 120 instead of the callee telephone number Dno, as shown in FIG. 14B. The call destination name Dname is assigned to display a call instruction (step S936). Thereafter, the control unit 130 advances the control to step S938. If the two passwords do not match and the input password is not authenticated (NO in step S934), control unit 130 advances control to step S930.

  If the password is not input within the predetermined time (NO in step S926 and YES in step S928), control unit 130 advances control to step S930.

  When the control proceeds to step S930, control unit 130 waits for a call cancel operation of call button 110 to be performed. If the call canceling operation is performed with call button 110 (YES in step S930), control unit 130 stops the operation of bell sound output device 146 and stops the ringing sound (step S923). Thereafter, the control unit 130 returns the control to step S200 shown in FIG. 5 to display the standby screen.

  On the other hand, when the control proceeds to step S938, the control unit 130 performs telephone connection control such as off-hook based on the call destination telephone number Dno.

  Then, the control unit 130 determines whether or not a call cancel operation of the call button 110 is performed before the call is started (steps S940 and S942). Control branches according to the determination result.

  If a call cancel operation is performed with call button 110 before the call is started (NO in step S942 and YES in step S940), control unit 130 stops the ringing tone (step S950). Then, the control part 130 returns control to step S200 shown in FIG.

  If the call is started without the call cancel operation of call button 110 (NO in step S940 and YES in step S942), control unit 130 stops the ringing tone and waits for the end of the call (step S946). And S948). When the call ends (YES in step S948), control unit 130 returns control to step S200 shown in FIG.

(Secret mode change control)
FIG. 9 is a flowchart showing a control flow of secret mode change control (step S1000 in FIG. 5), which is a subroutine related to a program for realizing the function of mobile communication device 100.

  In the secret mode change control, first, the control unit 130 of the mobile communication device 100 determines whether or not the value of the temporary variable SMD is “1” (step S1002). Control branches according to the determination result.

  If the value of temporary variable SMD is not “1” (NO in step S1002), control unit 130 determines whether or not secret button 112 has been operated again before the password is input by operating numeric keypad 108. (Steps S1004 and S1006). If secret button 112 is re-operated before entering the password (NO in step S1006 and YES in step S1004), control unit 130 returns control to step S200 shown in FIG. 5 and waits without performing any control. Display the receiving screen. Note that the standby screen has a display that shows the secret setting mode. When the password is input without re-operating secret button 112 (NO in step S1004 and YES in step S1006), control unit 130 stores the input password and password memory area 132C of memory device 132. It is determined whether or not the current password matches (step S1008). If the two match and the input password is authenticated (YES in step S1008), control unit 130 substitutes “1” for temporary variable SMD and sets the data display mode to the secret data display mode (step S1010). The variable SMD “1” is temporarily stored in the temporary memory area 132D of the memory device 132. Then, the control part 130 returns control to step S200 shown in FIG. If they do not match and the input password is not authenticated (NO in step S1008), control unit 130 returns control to step S200 shown in FIG. 5 without performing any control.

  If the value of temporary variable SMD is “1” (YES in step S1002), control unit 130 assigns “0” to temporary variable SMD and sets the data display mode to the secret data non-display mode ( Step S1012). This variable SMD “0” is temporarily stored in the temporary memory area 132D. Then, the control part 130 returns control to step S200 shown in FIG.

(Telephone book entry control)
FIG. 10 is a flowchart showing a control flow of one entry entry control (step S1100 in FIG. 5), which is a subroutine related to a program for realizing the function of mobile communication device 100.

  In this one-phone book entry control, first, the control unit 130 of the mobile communication device 100 substitutes “NULL” for the temporary variable Dno, “NULL” for the temporary variable Dname, and “0” for the temporary variable Dsec. (Step S1102). These variables Dno “NULL”, Dname “NULL”, and Dsec “0” are temporarily stored in the temporary memory area 132 D of the memory device 132.

  Then, the control unit 130 determines whether any of the input cancel operation of the call button 110, the input of the telephone number, the input of the name, the operation of the secret button 112, and the operation of the phone book registration button 114 has occurred. Determination is made (steps S1104, S1106, S1108, S1110 and S1112). Control branches according to the determination result.

  If an input cancel operation has been performed with call button 110 (YES in step S1104), control unit 130 returns control to step S200 shown in FIG. 5 and displays a standby screen without performing any control. .

  When a telephone number is input by operating numeric keypad 108 (YES in step S1106), control unit 130 substitutes “input telephone number” into temporary variable Dno (step S1118). This variable Dno “input telephone number” is temporarily stored in the temporary memory area 132D. Thereafter, the control unit 130 returns the control to step S1104.

  When a name is input by operating numeric keypad 108 (YES in step S1108), control unit 130 substitutes “input name” for temporary variable Dname (step S1120). This variable Dname “input name” is temporarily stored in the temporary memory area 132D. Thereafter, the control unit 130 returns the control to step S1104.

  If secret button 112 is operated (YES in step S1110), control unit 130 determines whether or not the value of temporary variable Dsec is “0” (step S1122). If the value of temporary variable Dsec is “0” (YES in step S1122), control unit 130 changes the value to “1” (step S1126), and if the value of temporary variable Dsec is not “0”. (NO in step S1122), the value is changed to “0” (step S1124). The changed value of the variable Dsec is temporarily stored in the temporary memory area 132D. And the control part 130 returns control to step S1104.

  If the telephone book registration button 114 is operated (YES in step S1112), the control unit 130 determines whether both the telephone number and the name are input (temporary variable Dno ≠ NULL and temporary variable Dname ≠ NULL). It is determined whether or not (step S1114).

  When the above determination condition is satisfied (YES in step S1114), control unit 130 causes temporary variable Adr [DCNT]. no is set to “temporary variable Adr [DCNT]. The name “input name Dname” is set to the temporary variable Adr [DCNT]. The value “sec of the set variable sec D” is substituted for sec, and “1” is added to the current number of registered data (DCNT ++) (step S1116). As a result, one new data is registered in the phone book data Adr [n]. The variable Adr [DCNT]. no “Dno”, Adr [DCNT]. name "Dname" and Adr [DCNT]. sec “Dsec” is temporarily stored in the temporary memory area 132D. Then, the control part 130 returns control to step S200 shown in FIG.

  If the above condition is not satisfied (NO in step S1114), control unit 130 returns control to step S1104 without performing any control.

  None of the above-described input cancel operation of the call button 110, the input of the telephone number, the input of the name, the operation of the secret button 112, and the operation of the phone book registration button 114 occurred (NO in steps S1104 to S1112). ), The control unit 130 returns the control to step S1104 as it is.

  A series of control related to the above steps S1104 to S1112 is repeatedly executed at least until an input cancel operation is performed or a telephone number and a name are input and a telephone book registration operation is performed.

(Phonebook list display control)
FIG. 11 is a flowchart showing a control flow of telephone directory list display control (step S1200 in FIG. 5), which is a subroutine related to a program for realizing the function of mobile communication device 100.

  In this phone book list display control, in the secret data display mode, as shown in FIG. 15A, all registered data of the phone book data Adr [n] is displayed as a list on the display 120 and vice versa. In the secret data non-display mode, only registered data other than the secret data is displayed as a list on the display 120 as shown in FIG.

  Specifically, first, the control unit 130 of the mobile communication device 100 sets “number of phone book registrations” in the variable C, “0” in the phone book data array index i, and “0” in the display array index j. Are respectively substituted (step S1202).

  Then, the control unit 130 determines whether or not the phone book registration number C is “0” (step S1204). If NO in this step, the control proceeds to step S1206, and if YES, the control returns to step S200 shown in FIG. 5 to display the standby screen.

  When control proceeds to step S1206, control unit 130 determines whether or not the data display mode is a secret data non-display mode (temporary variable SMD = 0). In the secret data non-display mode (temporary variable SMD = 0) (YES in step S1206), control unit 130 advances the control to step S1208. If it is not the secret data non-display mode, that is, the secret data display mode (temporary variable SMD = 1) (NO in step S1206), control unit 130 causes control to jump to step S1210.

  In step S1208, control unit 130 determines that temporary variable Adr [i]. It is determined whether sec = 1. Temporary variable Adr [i]. If the value of sec is not “1”, that is, normal data (NO in step S1208), control unit 130 advances control to steps S1210 and S1212. Temporary variable Adr [i]. If the value of sec is “1”, that is, secret data (YES in step S1208), control unit 130 causes control to jump to step S1216.

  When the control proceeds to steps S1210 and S1212, the control unit 130 causes the temporary variable T_Adr [j]. No is set to “Adr [i] .no”, and the temporary variable T_Adr [j]. “Adr [i] .name” is set in name, and temporary variable T_Adr [j]. After substituting “Adr [i] .sec” for sec, T_Adr [j]. no and T_Adr [j]. “name” is displayed in the (j + 1) th position. At this time, the variable T_Adr [j]. no “Adr [i] .no”, T_Adr [j]. name "Adr [i] .name" and T_Adr [j]. sec “Adr [i] .sec” is temporarily stored in the temporary memory area 132D. Thereafter, the control unit 130 adds “1” to the array index j (j ++) (step S1214), and then advances the control to step S1216.

  When the control proceeds to step S1216, the control unit 130 adds (i ++) “1” to the array index i.

  Then, the control unit 130 confirms whether the value of the variable C indicating the number of registered phone books matches the value of the array index i (the current value of the array index i) added in step S1216 (C = i). It is determined whether or not (step S1218). If the value of variable C matches the value of current array index i (YES in step S1218), control unit 130 performs telephone directory selection control (step S1300). This telephone directory selection control will be described in detail later. If the value of variable C does not match the current value of array index i (NO in step S1218), control unit 130 returns control to step S1206 as it is.

  The series of control in steps S1206 to S1218 is repeatedly executed until the values of both the variable C and the array index i match.

(Phonebook selection control)
FIG. 12 is a flowchart showing a control flow of telephone directory selection control (step S1300 in FIG. 11), which is a subroutine related to a program for realizing the function of mobile communication device 100.

  Referring to FIG. 12, in the telephone directory selection control, first, control unit 130 of mobile communication device 100 substitutes “0” into telephone directory data array index i (= memory No.) (step S1302).

  Then, the control unit 130 displays a cursor on the (i + 1) th data on the display 120 (step S1304).

  Thereafter, it is determined whether any of the cursor up movement operation of the cursor key 118, the cursor down movement operation of the cursor key 118, the call operation of the call button 110, and the display end operation of the phone book list display button 116 has occurred. Determination is made (steps S1306, S1308, S1310, and S1312). Control branches according to the determination result.

  If a cursor up operation is performed with cursor key 118 (YES in step S1306), control unit 130 determines whether the data currently displayed by the cursor is the first data (step S1314). If it is not the top data (NO in step S1314), the control unit 130 deletes the cursor on the (i + 1) th data (that is, deletes the current cursor display) and subtracts “1” from the array index i (i−). -) (Steps S1316 and S1318). Thereafter, the control unit 130 returns the control to step S1304. As a result, a cursor is displayed on the data in the column one level above. If it is head data (YES in step S1314), control unit 130 returns control to step S1304 without performing any control.

  If the cursor key 118 has been moved downward (YES in step S1308), control unit 130 determines whether or not the data currently displayed by the cursor is the final data (step S1320). If it is not the final data (NO in step S1320), the control unit 130 deletes the cursor on the (i + 1) th data (that is, deletes the current cursor display) and adds “1” to the array index i (i ++). (Steps S1322 and S1324). Thereafter, the control unit 130 returns the control to step S1304. As a result, a cursor is displayed on the data in the lower column. If it is final data (YES in step S1314), control unit 130 returns control to step S1304 without performing any control.

  When a call operation is performed with call button 110 (YES in step S1310), control unit 130 sets “T_Adr [i] .no” as temporary variable Dno and “T_Adr [i] .name” as temporary variable Dname. Is substituted for “T_Adr [i] .sec” in the temporary variable Dsec. These variables Dno “T_Adr [i] .no”, Dname “T_Adr [i] .name”, and Dsec “T_Adr [i] .sec” are temporarily stored in the temporary memory area 132D of the memory device 132. Thereafter, the control unit 130 shifts the control to step S912 shown in FIG. As a result, an outgoing instruction, telephone connection, and the like are made in a manner corresponding to the contents of the selected telephone directory data.

  If a display end operation has been performed by telephone book list display button 116 (YES in step S1312), control unit 130 returns control to step S200 shown in FIG. 5 to display a standby screen.

  None of the above-described cursor key 118 movement operation, cursor key 118 cursor movement operation, call button 110 call operation, and phone book list display button 116 display end operation occurred (step S1306). If NO in step S1312), the control unit 130 returns the control to step S1304.

<Operation>
The mobile communication device 100 operates as follows.

  When a call instruction is given to another communication device in which data is registered as normal data (variable sec = 0) in the phone book data, it is registered in the phone book data at the time of calling as shown in FIG. A call instruction display is performed by assigning the name of the called party.

  On the other hand, when a call is issued to another communication device registered as secret data (variable sec = 1) in the phone book data or another communication device not registered in the phone book data. As shown in FIG. 14A, only a call destination telephone number is assigned at the time of a call and a call instruction display is made. In particular, if call destination data is registered as secret data in the telephone directory data, actual call control is not performed at this point. The actual call control is performed only when the password is input within a predetermined time and the input password is authenticated. At this time, no screen display prompting the input of a password is performed. If the data related to the call destination is designated as secret data when the call control is actually performed, the call indication display is made instead of the call destination telephone number as shown in FIG. The display mode is changed to the name given to the callee. If the data related to the call destination is not registered in the phone book data, the name of the call destination cannot be specified as a matter of course.

<Action and effect>
According to the present embodiment, the following operations and effects are achieved.

  (1) From the viewpoint of call display control, in this embodiment, when a communication start instruction is given in the secret data non-display mode, this is used as a trigger to a predetermined communication destination registered in the phone book data. It is determined whether or not it is a communication start instruction. When it is determined that it is an instruction to start communication with a predetermined communication destination registered in the telephone book data, the telephone number of the predetermined communication destination and the name of the communication destination are displayed. On the other hand, in the secret data display mode, a communication start instruction is given, and when it is determined that the communication start instruction is a communication start instruction to a predetermined communication destination registered in the phone book data, The password entered within a predetermined time is compared with the stored authentication information. As a result of this authentication determination, when the password input is authenticated, the display of the transmission information is changed to a display mode including a name for specifying the communication destination for which the communication start instruction has been given.

  (2) From the viewpoint of call communication control, in this embodiment, when a communication start instruction is given in the secret data display mode, a message indicating the start of communication is displayed, that is, dummy call control is performed. At the same time, it is determined whether or not the communication start instruction is a communication start instruction to a predetermined communication destination registered in the telephone directory data. When it is determined that it is an instruction to start communication to a predetermined communication destination registered with data, from the above dummy call control to actual communication start control unless the input password is authenticated within a predetermined time. Is not switched.

  From the viewpoints of the above (1) and (2), the mobile communication device 100 can prevent leakage of personal information associated with unauthorized use without invalidating the calling instruction or applying a key lock. , It will be more secure. Of course, unauthorized use by a third party can be sufficiently suppressed.

  By the way, as for whether or not the secret data should be excluded from the list of incoming call history data, there is a current situation that a delicate problem may occur due to the design specifications of the software. Specifically, if the secret data is left in the list of incoming call history data, the privacy information of the owner will be leaked. Conversely, if the secret data is removed from the list of incoming call history data, the password will be used to check who received the call. Input is always required.

  In contrast to the current situation, in the present embodiment, as described above, when data related to a predetermined communication destination is registered as secret data in the phone book data, communication is actually started along with authentication of the input password. While the control is being performed, the transmission information display mode is changed to a mode different from the display mode before password authentication as described in (1) above, that is, when an actual communication start instruction is issued (telephone Since it is determined whether or not an authentication password is required (when the number is confirmed), for example, the incoming call history data is displayed and the outgoing call history data is not displayed. "Does it have this specification?" Or "Does it have a bug?" As a result, there are ripple effects such as a reduction in development load when designing software.

  Here, in the present embodiment, as described above, communication is performed only in the secret data display mode (in other words, only for a communication device that is secretized) on the condition that the password input is authenticated. The transmission display control is performed so that the previous name is displayed because the communication device to be controlled is a “close friend or acquaintance” who can be said to be a regular user of the mobile communication device 100 in a sense. This is because it is a communication terminal. In other words, it is better to make a call rather than not to call an illegal user calling the “close friend or acquaintance” of the owner of the mobile communication device 100. The unauthorized user can be identified through “close friend or acquaintance”, but in this embodiment, the call is not made unless the password input is authenticated. The reason is that in this embodiment, an unknown person is not assumed as an unauthorized user. The main assumptions are not “parents” and “bad friends”, that is, those that can be declared “crimes” even if they are fraudulent users, but rather “mischievous” and “excessive” It is supposed to be a “selfish act of parent who is worried about children” and “invasion of privacy without consideration by acquaintance”. Therefore, in spite of the above-described problems, the problems arising from the following scenes or the like that secretly register certain address information can be solved.

  As an example of the above scene, I recently proposed and exchanged phone numbers with friends and less than a lover, I still know only my true best friend, or even my parents do not know, address information, For example, “Your daughter has been getting along with a guy you do n’t know recently” and you ’re taking strange actions such as making a call from a mobile phone ’s call history that you ’ve left on the table. When in trouble, not only the act of making a call is prevented, but also leakage (display) of information (name) of the destination of the call can be prevented in advance, and various other ripple effects are produced.

  The present invention is not limited to the above embodiment. In the above embodiment, when it is determined that the data registered in the phone book data is designated as secret data, or is not registered in the phone book data, and is a communication start instruction to a predetermined communication destination Only the example in which the control of the present invention is executed has been described. However, the present invention is not limited to such a configuration. For example, regardless of whether there is normal data or secret data, the screen is displayed when there is a call instruction to the phone number registered in the phone book data, but the call is actually started. Instead, only when the input password is authenticated within a predetermined time after the transmission instruction is given, the above-mentioned screen display mode may be changed to perform actual transmission start control. In the above embodiment, an example in which the present invention is applied to telephone communication (telephone communication) has been described. However, the present invention is not limited to such a configuration. For example, the present invention may be applied to text communication such as mail communication. Even in this case, the object of the present invention can be sufficiently achieved. It goes without saying that various design changes and modifications can be made within the scope of the claims attached to this specification.

  In other words, the embodiment disclosed in this specification is merely an example, and the present invention is not limited to the embodiment described above. The scope of the present invention is indicated by the claims of the claims after taking into account the description of the detailed description of the invention, and includes all modifications within the meaning and scope equivalent to the words described therein. .
