Hereinafter, embodiments will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a diagram illustrating a configuration of a communication terminal according to the first embodiment.

  The communication terminal 1 is a case where the privacy mode is set, and when the number of communication history information to be displayed is less than a predetermined number, the communication terminal 1 generates the fictitious communication history information and sets the fictitious history information as the display target. Is displayed in addition to the call history.

  As shown in FIG. 1, such a communication terminal 1 includes a communication identification information storage unit 2, a communication history storage unit 3, a communication execution unit 4, an acquisition unit 5, a comparison unit 6, a fictitious communication history generation unit 7 and a communication. A history display unit 8 is provided.

  The communication identification information storage unit 2 displays communication history information including communication identification information for executing communication with a communication partner, and communication execution status information together with communication identification information of the communication partner that executed communication. Are stored in association with display attributes to be displayed or secret attributes to be concealed. Note that the communication identification information is, for example, a mail address or a telephone number, and communication can be performed by identifying a communication partner based on these identification information. The information on the execution status of communication is information indicating the communication time, communication time, communication success / failure, etc. when communication with the communication partner is executed. For example, when an incoming call is received, the communication execution status includes incoming time, call time, answer / absence / hold, etc. Also, those corresponding to the display attribute are always displayed on the display device, and those corresponding to the confidential attribute are not displayed when the mode is switched to the privacy mode.

The communication history storage unit 3 can store communication history information for the number of display items that can be displayed on the display device. Details of the communication history storage unit 3 will be described later.
Each time the communication execution unit 4 executes communication, the communication execution unit 4 updates communication history information with the communication partner in the communication history storage unit 3.

The acquisition unit 5 refers to the communication identification information storage unit 2 and acquires the number of display attributes in the communication history storage unit 3.
The comparison unit 6 compares the number of display attributes acquired by the acquisition unit 5 with the number of display items that can be displayed on the display device.

  The fictitious communication history generation unit 7 is configured when the privacy mode is set, and the number of communication history information to be displayed in the comparison result of the comparison unit 6 is less than the number of display items that can be displayed on the display device. Next, fictitious communication history information is generated.

  When the privacy mode is not set, the communication history display unit 8 displays the communication history information including the communication history information corresponding to the identification information of the communication partner to be concealed. When the privacy mode is set, the fictitious history information generated by the fictitious communication history information 7 is displayed in addition to the communication history information to be displayed.

Next, a specific example of the communication history storage unit 3 provided in the communication terminal 1 having such a configuration will be described.
FIG. 2 is a diagram for explaining a communication history displayed on the display device of the communication terminal according to the first embodiment.

  FIG. 2A schematically shows a storage state of the communication history storage unit 3 that stores communication history information for each communication, and each block represents one piece of communication history information. The storage display range X represents a range in which the communication history storage unit 3 can store and display communication history information. Blocks S1 and S2 represent communication history information corresponding to the secret attribute, and all blocks other than S1 and S2 represent communication history information corresponding to the display attribute. FIG. 2B is displayed when the privacy mode is switched without applying the first embodiment, and FIG. 2C is displayed when the privacy mode is switched to the first embodiment. Each represents communication history information. Note that blocks displayed with broken lines represent communication history information that is not displayed. The blocks A1 and A2 represent the aerial communication history information generated by the aerial communication history generation unit 7.

  First, the communication history storage unit 3 of the communication terminal 1, for example, as shown in FIG. 2A, every time communication is executed by the communication execution unit 4, the communication identification information of the communication partner and the communication Communication history information including execution status information is stored in the storage display range X (in this case, in order from the bottom).

  For example, when the communication terminal 1 is not switched to the privacy mode (normally displayed), all communication history information within the storage display range X is displayed on the display device regardless of the display / confidential attribute.

Next, an example of a communication history display method in the communication terminal 1 will be described with reference to FIGS. 1 and 2.
First, when the communication terminal 1 is not switched to the privacy mode (normally displayed), the communication history display unit 8 displays the communication history information in the storage display range X regardless of the display / confidential attribute as described above. Display on the display device.

Next, display of communication history information when the communication terminal 1 is switched to the privacy mode will be described.
For comparison, a case where the privacy mode is switched to without applying the first embodiment will be described.

  In this case, as shown in FIG. 2B, only the communication history information S1 and S2 corresponding to the confidential attribute among the communication history information in the storage display range X is not displayed, but the display in the storage display range X is displayed. Only the communication history information corresponding to the attribute is displayed. That is, the number of display items displayed on the display device is reduced as compared with the case of FIG.

  A mobile phone will be described as an example of a communication terminal switched to such a privacy mode. In a mobile phone, for example, generally, a maximum of about 30 call histories can be stored in the communication history storage unit 3 as communication history information. For this reason, when a certain period of time elapses after the use of the mobile phone is started, the maximum number that can be stored is easily reached. In addition, the call history that has reached the maximum number is erased for each call and the latest call history is stored and the maximum number is maintained unless the user deletes the call history. In this situation, as described above, when the mode is switched to the privacy mode, the display number of the call history is reduced from the maximum number. In particular, when the usage period has passed sufficiently, the third party feels that the call history is low, so there is a high possibility that privacy mode setting and data concealment are suspected.

Therefore, when switching to the privacy mode executed in the first embodiment, the following communication history display processing is executed.
First, every time communication is executed by the communication execution unit 4, the communication history information in the communication history storage unit 3 is updated.

  When a communication history display request is executed by the user to the communication terminal 1, the acquisition unit 5 corresponds to the display attribute set in the communication identification information of the communication identification information storage unit 2 from the communication history storage unit 3. Communication history information including communication identification information to be acquired is acquired. In this case, the number of communication history information corresponding to the display attribute acquired by the acquisition unit 5 at this time is the number of storage records in the storage display range X−2 cases (communication history information S1, S2). is there.

  The comparison unit 6 includes the number of pieces of communication history information corresponding to the display attributes acquired by the acquisition unit 5 (the number of stored cases in the storage display range X−two cases (communication history information S1, S2)) and the display that can be displayed on the display device. Compare the number.

  Since the comparison result of the comparison unit 6 is less than the number of display items that can be displayed on the display device, the fictitious communication history generation unit 7 has a comparison result of the display attribute acquired by the acquisition unit 5. The fictitious communication history information A1, A2 is generated.

  When the number of pieces of communication history information corresponding to the display attributes acquired by the acquisition unit 5 is less than the number of displays that can be displayed on the display device, the communication history display unit 8 sets the communication history information S1, corresponding to the confidential attribute. Hide S2. Further, the communication history display unit 8 displays the communication history information for the number of display items as shown in FIG. 2C by adding the aerial communication history information A1 and A2 generated by the fictitious communication history generation unit 7. To do.

  Thus, the communication terminal 1 is a case where the privacy mode is set, and when the number of pieces of communication history information to be displayed is less than a predetermined number, the communication terminal 1 generates the fictitious communication history information, Displayed in addition to the call history to be displayed. For this reason, the communication history display unit 8 can display the communication history information for the number of display items even if the communication history information corresponding to the confidential attribute is not displayed. As a result, even if the mode is switched to the privacy mode, the number of communication histories displayed on the display device of the communication terminal 1 does not decrease, so a third party may be suspicious of setting the privacy mode and concealing data. Can be prevented.

[Second Embodiment]
In the second embodiment, the first embodiment will be specifically described. In the second embodiment, a case where a mobile phone is used as a communication terminal will be described as an example.

  In general, a mobile phone has about 1000 to 2000 records of mail transmission / reception history and telephone directory functions. In addition, as the usage period of the mobile phone becomes longer, the number of times various information is deleted / added by the user increases. However, even if the usage period of the mobile phone becomes long, generally, the mail transmission / reception history and the telephone directory function do not reach the maximum number of records due to the large number of records. For this reason, when switching to the privacy mode, the mail transmission / reception history and the phone book function are not concealed and suspicious by a third party even if the number of displayed items decreases, so it is kept secret. There is little chance of being noticed.

  On the other hand, as described above, only about 30 phone calls can be recorded, so it is easy to reach the maximum number of records with the length of use, and the number of records decreases when switching to privacy mode. Then, there is a high possibility of being suspected by a third party. Therefore, in the second embodiment, a means for preventing the concealment of the call history from being doubted by a third party will be described by taking the case of a call and a telephone number as examples of communication and communication identification information.

The call history update unit 14 updates the call history table 12 by adding the latest call history information generated by making and receiving calls by the call execution unit 13.

The call history update unit 14 can update the call history table 12 by performing the above process every time when the call execution unit 13 performs outgoing / incoming calls.
Returning again to FIG. The call history display execution unit 15 executes display processing of call history information based on an operation input for a display request to the user input unit 10e.

When the display process is executed by the call history display execution unit 15, the mode identification unit 16 identifies whether or not the mobile phone 10 is currently set to the privacy mode.
When the mode identification unit 16 identifies that the privacy mode is set, the attribute acquisition unit 17 refers to the attribute status (display / confidential) set in the telephone number of the phone book database 11, The attribute corresponding to the telephone number included in the call history information recorded in the call history table 12 is specified. Then, the attribute acquisition unit 17 acquires call history information including a telephone number corresponding to the specified attribute in the call history table 12, and counts the number of acquired call history information.

  The comparison unit 18 first compares the number of call history information corresponding to the display attribute of the call history table 12 with the number of display of the call history table 12. Furthermore, the comparison unit 18 compares a use period from when the use of the mobile phone 10 is started to when the display process is executed with a predetermined period set in advance.

  First, when the mode identifying unit 16 identifies that the display history generating unit 19 has not switched to the privacy mode, the display history generating unit 19 displays the number of displayed items from the latest call in the call history table 12 regardless of the attribute setting status. Select call history information for. Further, the display history generation unit 19 selects and adds a name corresponding to the telephone number included in the call history information from the telephone directory database 11 to the selected call history information.

  Further, when the mode identification unit 16 identifies that the mode is switched to the privacy mode, the display history generation unit 19 performs the following process according to the result of the comparison process performed by the comparison unit 18.

  When the number of call history information corresponding to the display attribute of the call history table 12 is equal to or greater than the number of display, the following processing is executed. First, the display history generation unit 19 refers to the display attributes set for the telephone numbers in the telephone directory database 11 and updates only the call history information including the telephone numbers corresponding to the display attributes from the call history table 12. Select the number of items displayed from the call. Next, the display history generation unit 19 selects the name corresponding to the telephone number included in the call history information from the phone book database 11 and adds the call history information corresponding to the display attributes for the number of selected display items. To do.

  Next, the following processing is executed when the number of call history information corresponding to the display attribute of the call history table 12 is less than the display number and the usage period is less than the predetermined period. First, the display history generation unit 19 refers to the display attributes set for the telephone numbers in the telephone directory database 11 and selects only the call history information including the telephone numbers corresponding to the display attributes from the call history table 12. To do. Next, the display history generation unit 19 selects and adds the name corresponding to the telephone number included in the call history information from the telephone directory database 11 to the selected call history information.

  Then, when the number of call history information corresponding to the display attribute of the call history table 12 is less than the display number and the usage period is equal to or longer than the predetermined period, the following process is executed. The display history generation unit 19 performs the second process, and further adds the aerial communication history information generated by the aerial call history generation unit 21 described later to the communication history information to which the name is added.

The display processing unit 20 displays the call history information and the like added with the name generated by the display history generating unit 19 on the display unit 10d.
The fictitious call history generation unit 21 registers the display attribute of the phone book database 11 when the number of call history information corresponding to the display attribute of the call history table 12 is less than the display number and the usage period is equal to or longer than the predetermined period. An arbitrary name is selected from the information, and fictitious call history information is generated from the selected name and an arbitrary call time, call time, and the like.

  The fictitious call history generation unit 21 can set a range to be generated in advance when generating fictitious call history information. For example, the name can be set in the telephone directory database 11 such that the name is selected from a group, company, school, or the like. As for the call time and the call time, for example, the call time can be set in advance from a time zone in which the user usually uses the telephone. The call date is arbitrarily selected from the start of use until the display process is executed. By setting the range in which the fictitious call history information is generated in this way in advance, the fictitious call history information arbitrarily generated by the fictitious call history generation unit 21 is not unnatural, so that the third party Can be prevented from being suspicious.

Next, a processing procedure for displaying a call history performed on the mobile phone 10 will be described.
FIG. 8 is a flowchart showing a processing procedure for executing display of a call history in the mobile phone according to the second embodiment.

The next process proceeds to step S22 if it is identified that the privacy mode is not set, and proceeds to step S23 if it is identified that the privacy mode is set.

[Step S22]
The display history generation unit 19 selects 30 pieces of call history information from the latest call in the call history table 12 regardless of the attribute setting status. Further, the display history generation unit 19 selects and adds a name corresponding to the telephone number included in the call history information from the telephone directory database 11 to the selected call history information. The display processing unit 20 displays the call history information and the like added with the name generated by the display history generating unit 19 on the display unit 10d. When the call history information stored in the call history table 12 is less than 30, all the call history information is selected, and the name is added to the selected call history information and displayed on the display unit 10d. Is done.

[Step S23]
The attribute acquisition unit 17 refers to the display attribute set for the telephone number in the telephone directory database 11 and identifies the display attribute corresponding to the telephone number included in the call history information recorded in the call history table 12. . Then, the attribute acquisition unit 17 acquires call history information including a telephone number corresponding to the specified display attribute in the call history table 12, and counts the number of acquired call history information.

[Step S24]
The comparison unit 18 compares the number of call history information corresponding to the display attribute acquired in step S <b> 23 and the number of call history information displayed in the call history table 12. The next process proceeds to step S25 if the number of call history information corresponding to the display attribute is equal to or greater than the number of display. If the number of call history information corresponding to the display attribute is not equal to or greater than the number of display, that is, if the number of call history information corresponding to the display attribute is less than the display number, the process proceeds to step S26.

The display history generation unit 19 selects the name corresponding to the telephone number included in the call history information from the telephone directory database 11 and adds it to the selected call history information. Furthermore, the fictitious communication history information generated by the fictitious call history generation unit 21 described later is added to the communication history information to which the name is added. The display processing unit 20 displays the call history information to which the name is added and the fictitious call history information on the display unit 10d.

According to such a flow, processing display of the call history of the mobile phone 10 is executed.
Next, the display processing of the mobile phone 10 will be specifically described based on the above processing flow.

[Example 1]
In the first embodiment, a case where the number of call history information corresponding to the display attribute recorded in the call history table is larger than the number of display cases will be described.

First, a specific example when the registration information registered in the telephone directory database 11 is displayed on the display unit 10d will be described.
FIG. 9 is a diagram illustrating a display example of registration information registered in a telephone directory database included in the mobile phone according to the second embodiment.

  On the display screen 10d1 of the display unit 10d, a maximum of seven pieces of registration information can be displayed on one page. In FIG. 9, seven pieces of registration information are displayed on the first page of nine pages from the telephone directory database 11. Has been. The displayed registration information can be designated by the user from the items in FIG. 5. In FIG. 9, for example, “name”, “phone number”, and “confidential attribute (display attribute)” are displayed. It is displayed. When the “confidential attribute” is ON, the confidential attribute is set, and when the “confidential attribute” is OFF, it indicates that the display attribute is set. In the phone book database 11 shown in FIG. 9, the secret attribute is set only for “Akiko Tanaka”, and the display attribute is set for all other than that.

Next, call history information recorded in the call history table 12a will be described. In the following, a call history when a call is received will be described.
FIG. 10 is a diagram illustrating a specific example of a call history recorded in a call history table included in the mobile phone according to the second embodiment.

  In the call history table 12a, as shown in FIG. 10, 60 pieces of call history information including “incoming date”, “incoming time”, “incoming call type”, and “incoming phone number” are recorded. As for “incoming call type”, “0” indicating “call”, “1” indicating “missed call”, and “2” indicating “message memo” are recorded as described in FIG. There are four incoming calls from the telephone number “090333334444” (corresponding to “Akiko Tanaka” for which the confidential attribute is set), and there is no incoming call from the telephone number in the call history not shown in FIG. And

  A description will be given of a case where the privacy mode is not set in the mobile phone 10 including the telephone directory database 11 and the call history table 12a, that is, normal display.

  When an operation input for a call history display request is performed on the input unit 10e by the user, the call history display executing unit 15 executes display processing. Then, the mode identifying unit 16 identifies that the privacy mode is not set (step S21).

  The display history generation unit 19 selects 30 pieces of call history information from the latest incoming call in the call history table 12a. Further, the display history generation unit 19 selects and adds a name corresponding to the telephone number included in the call history information from the telephone directory database 11 to the selected call history information. The display processing unit 20 displays the call history information added with the name generated by the display history generation unit 19 on the display screen 10d1 of the display unit 10d as shown in FIG. 11 (step S22).

FIG. 11 is a diagram illustrating a display example of a normal display of a call history recorded in a call history table included in the mobile phone according to the second embodiment.
In the display screen 10d1 of the display unit 10d in FIG. 11, a maximum of five call history information can be displayed on one page, and five call history information on the first page of the six pages are displayed. The display screen 10d1 displays the name associated with the telephone number and the type content associated with the incoming call type number. As shown in FIG. 11, when the privacy mode is not set, 30 pieces of call history information are displayed from the call history table 12a regardless of the setting of the concealment / display attribute.

Next, a case where the privacy mode is set will be described.
After an operation input of a call history display request to the input unit 10e by the user, the call history display executing unit 15 executes display processing, and the mode identifying unit 16 identifies that the privacy mode is set (step S21). .

  The attribute acquisition unit 17 refers to the display attribute set for the telephone number in the telephone directory database 11 and identifies the display attribute corresponding to the telephone number included in the call history information recorded in the call history table 12a. . Then, the attribute acquisition unit 17 acquires call history information including a telephone number corresponding to the specified display attribute in the call history table 12a, and counts the number of acquired call history information. In this case, since the secret attribute is set only for “Akiko Tanaka” in the telephone directory database 11, the attribute acquisition unit 17 determines the number of call history information other than “Akiko Tanaka” from the call history table 12a (56 cases). = 60-4 cases) is acquired (step S23).

  The comparison unit 18 compares the number of call history information (56) corresponding to the acquired display attribute with the number of display of the call history information (30) displayed in the call history table 12a (step S24).

  The display history generation unit 19 refers to the display attribute set for the telephone number in the telephone directory database 11 and from the call history table 12a, only the call history information including the telephone number corresponding to the display attribute is obtained from the latest incoming call. Select 30 items. Then, the display history generation unit 19 selects the name corresponding to the telephone number included in the call history information from the telephone directory database 11 and adds it to the call history information corresponding to the selected 30 display attributes. . The display processing unit 20 displays the 30 call history information with the names added on the display screen 10d1 of the display unit 10d as shown in FIG. 12 (step S25).

FIG. 12 is a diagram showing a display example of the privacy mode of the call history recorded in the call history table provided in the mobile phone according to the second embodiment.
It can be seen that the call history information of “Akiko Tanaka” corresponding to the confidential attribute is not displayed on the display screen 10d1 of the display unit 10d in FIG. 12, and the display number is not different from the case of FIG.

[Example 2]
In the second embodiment, a case will be described in which the number of call history information corresponding to the display attribute recorded in the call history table is smaller than the number of display. In the second embodiment, the telephone directory database 11 is the same as that in the first embodiment, and a case where a call is received will be described.

First, the call history information recorded in the call history table 12b will be described.
FIG. 13 is a diagram showing another specific example of the call history recorded in the call history table provided in the mobile phone according to the second embodiment.

  In the call history table 12b, as shown in FIG. 13, nine pieces of call history information including “incoming date”, “incoming time”, “incoming call type”, and “incoming phone number” are recorded. As described above, “0” indicating “call”, “1” indicating “missed call”, and “2” indicating “message memo” are recorded as “incoming call type”. There are also four incoming calls from the telephone number “090333334444” (corresponding to “Akiko Tanaka” for which the confidential attribute is set).

  A description will be given of a case where the privacy mode is not set in the mobile phone 10 including the telephone directory database 11 and the call history table 12b, that is, normal display.

  An operation input for a call history display request is performed on the input unit 10e by the user, and the call history display executing unit 15 executes display processing. Then, the mode identifying unit 16 identifies that the privacy mode is not set (step S21).

  The display history generation unit 19 selects all the call history information in the call history table 12b. Further, the display history generation unit 19 selects and adds a name corresponding to the telephone number included in the call history information from the telephone directory database 11 to the selected call history information. The display processing unit 20 displays the call history information added with the name generated by the display history generation unit 19 on the display screen 10d1 of the display unit 10d as shown in FIG. 14 (step S22).

FIG. 14 is a diagram illustrating another display example of the normal display of the call history recorded in the call history table included in the mobile phone according to the second embodiment.
As shown in FIG. 14, when the privacy mode is not set, all call history information is displayed from the call history table 12b regardless of the setting of the concealment / display attribute.

Next, a case where the privacy mode is set will be described.
An operation input for a call history display request is performed on the input unit 10e by the user, and the call history display executing unit 15 executes display processing. Then, the mode identification unit 16 identifies that the privacy mode is set (step S21).

  The attribute acquisition unit 17 refers to the display attribute set for the telephone number in the telephone directory database 11 and identifies the display attribute corresponding to the telephone number included in the call history information recorded in the call history table 12b. . Then, the attribute acquisition unit 17 acquires call history information including a telephone number corresponding to the specified display attribute in the call history table 12b, and counts the number of acquired call history information. In this case, since the secret attribute is set only for “Akiko Tanaka” in the telephone directory database 11, the attribute acquisition unit 17 determines the number of call history information other than “Akiko Tanaka” from the call history table 12b (5 cases). = 9 cases-4 cases) is acquired (step S23).

  The comparison unit 18 compares the number of call history information (5) corresponding to the acquired display attribute with the number of call history information displayed (30) displayed in the call history table 12b (step S24).

Furthermore, the comparison unit 18 compares the use period from when the use of the mobile phone 10 is started to when the display process is executed with a predetermined period set in advance (step S26).
Here, when the usage period is less than the predetermined period (step S26: no), the display history generation unit 19 refers to the display attribute set in the telephone number of the telephone directory database 11 and refers to the call history table. From 12b, only five pieces of call history information including the telephone number corresponding to the display attribute are selected. Then, the display history generation unit 19 selects the name corresponding to the telephone number included in the call history information from the telephone directory database 11 and adds it to the selected five call history information. The display processing unit 20 displays the call history information and the like for the five cases generated by the display history generation unit 19 on the display screen 10d1 of the display unit 10d as shown in FIG. 15 (step S27).

  FIG. 15 is a diagram illustrating a display example when the privacy mode of the call history recorded in the call history table included in the mobile phone according to the second embodiment has not passed a certain period of use.

  On the display screen 10d1 of the display unit 10d in FIG. 15, the call history information of “Akiko Tanaka” corresponding to the confidential attribute is hidden, and the five call history information corresponding to the other display attributes are displayed. Yes. The number of displayed items is reduced as compared with the case of FIG. However, in this case, since the usage period of the mobile phone 10 is shorter than the predetermined period, the number of incoming calls may be small. Therefore, even if the number of displayed items decreases, the third party is unlikely to be suspicious of the privacy mode setting.

  On the other hand, the comparison unit 18 compares the usage period of the mobile phone 10 with a predetermined period. If the usage period is equal to or longer than the predetermined period (step S26: yes), the fictitious call history generation unit 21 An arbitrary name is selected from the display attribute registration information of the database 11. Furthermore, the fictitious call history generation unit 21, together with the selected name, for example, the call date and call generated in the range of “September 1 to 3”, “10 o'clock to 22:00”, “absence / response” Fictitious call history information including time and incoming call type is generated. The fictitious call history generation unit 21 obtains (25) fictitious call history information by subtracting the number (5) of call history information corresponding to the display attribute of the call history table 12b from the display number (30). Generate (step S28). Further, the fictitious call history generation unit 21 subtracts the number (5) of call history information corresponding to the display attribute of the call history table 12b from the actual call history number (number of records in the call history table 12b) (that is, It is also conceivable that the actual call history number is displayed as a result by generating the fictitious call history information (number of call history information corresponding to the confidential attribute).

  The display history generation unit 19 refers to the display attributes set for the telephone numbers in the telephone directory database 11 and selects all five pieces of call history information including the telephone numbers corresponding to the display attributes from the call history table 12b. To do. Then, the display history generation unit 19 selects and adds the name corresponding to the telephone number included in the call history information from the telephone directory database 11 to the five selected call history information. Further, the display history generation unit 19 adds the imaginary call history information to the call history information with the name added. The display processing unit 20 displays the call history information and the imaginary call history information on the display unit 10d as shown in FIG. 16 (step S29).

  FIG. 16 is a diagram showing a display example when the privacy mode is in the call history recorded in the call history table provided in the mobile phone according to the second embodiment and a certain usage period has passed.

  On the display screen 10d1 of the display unit 10d shown in FIG. 16, the call history information corresponding to the confidential attribute is concealed, and the call history information corresponding to the number of displays is displayed for 30 cases. In FIG. 16, five call history information items on page 2 of page 6 are displayed. According to this, the call history information of “Akiko Tanaka” corresponding to the confidential attribute is hidden, and the fictitious call history information for 25 cases added to the five call history information corresponding to the other display attributes. Is displayed. For this reason, 30 call history information items are apparently displayed.

  As described above, the mobile phone 10 can store more communication history information in the call history table 12 than the number of communication history information displayed on the display unit 10d. For this reason, the display history generation unit 19 can display the communication history information corresponding to the display attributes corresponding to the number of display items by hiding the communication history information corresponding to the confidential attribute in the call history table 12. Further, when the number of communication history information corresponding to the display attribute of the call history table 12 is smaller than the number of display, the fictitious call history information that is insufficient with respect to the display number is displayed according to the usage period of the mobile phone 10. It is possible to generate and display the communication history information corresponding to the display attribute and the fictitious call history information. As a result, even if the mode is switched to the privacy mode, the number of communication histories displayed on the display screen 10d1 of the display unit 10d of the mobile phone 10 does not decrease. It will be possible to prevent the concealment etc. from being suspicious.

  Note that at least some of the functions of the communication terminal 1 and the mobile phone 10 described in the above embodiments can be realized by a computer. In that case, a program describing the processing contents of the above functions is provided.
