Description

  The present invention is applied to, for example, a mobile phone, a PHS phone (PHS: Personal Handyphone System), a PDA device (PDA: Personal Digital Assistant) having a wireless communication function, a notebook personal computer device, a desktop personal computer device, and the like. In particular, the present invention relates to an information protection program and a terminal device that are intended to protect personal information stored in the terminal device.

  Mobile phones widely used today are provided with various functions such as a voice call function, an outgoing / incoming call history function, a mobile mail transmission / reception function, a telephone book function, an address book function, and a schedule book function. Then, the user registers telephone numbers and e-mail addresses of friends, family members, office associates, etc. using the telephone book function and the address book function, and registers the schedule using the schedule book function.

  In addition, when a phone call is received and the telephone number of the user who is the caller is registered in the telephone directory, the name and the like of the user are recorded in the incoming call history by the call / call history function. If the user who is the caller is not registered in the phone book, the caller / caller history function records the phone number of the user who is the caller in the incoming call history (the caller is the local station). (If the phone number is set to display on the other party ’s mobile phone display).

  Similarly, when making a call, if the telephone number of the user who is the call destination (the other party) is registered in the phone book, the call name / call history function allows the user's name and the like to be sent. If the user who is the destination is not registered in the telephone directory, the telephone number of the user who is the destination is recorded in the outgoing history by the outgoing / incoming history function.

  In addition, when a mobile mail is received, information (= contents) of the received electronic mail is stored in the memory, and the electronic mail address of the user who is the sender is registered in the address book. The user's name and the like are recorded in the incoming call history by the outgoing / incoming call history function, and if the e-mail address of the user who is the sender is not registered in the address book, the outgoing / incoming call history function Thus, the electronic mail address of the user is recorded as it is in the incoming call history.

  The same applies to the transmission of mobile mail. When the e-mail address of the user who is the destination (the other party) is registered in the address book, the name of the user is transmitted by the outgoing / incoming history function. If the e-mail address of the user who is the destination is not registered in the address book, the e-mail address of the user is recorded as it is in the outgoing history by the outgoing / incoming history function. .

In this way, mobile phones
1. Phone numbers registered in the phone book,
2. Outgoing and incoming phone numbers recorded in outgoing and incoming call history,
3. Outgoing and incoming email addresses recorded in outgoing and incoming call history,
4). The schedule recorded in the schedule book,
5). E-mail information sent and received (= content)
Etc. are memorized.

  Information such as phone numbers and e-mail addresses stored in such mobile phones is personal information. If it is illegally obtained by a third party, personal information will be leaked, and unauthorized use of personal information will occur. Cause inconvenience. For this reason, some mobile phones are provided with a secret function that hides the telephone numbers and e-mail addresses registered in the phone book or address book, or the contents of sent and received e-mails. Exists.

  Specifically, this secret setting is performed by inputting a personal identification number. When this secret setting is made, a secret function is activated, and a password entry screen is displayed when an operation for displaying a telephone book, an address book, a schedule book, or transmitted / received electronic mail is performed. Unless the correct password is entered on the password input screen, the telephone book, address book, schedule book, or sent / received electronic mail is not displayed.

  In addition, as described above, when the phone number or e-mail address of the user who is the sender is registered in the phone book or address book, when the user receives a call or e-mail, that user If the phone book or address book is set to a secret, the phone number or e-mail address is registered in this phone book or address book. Even if there is an incoming call from, the user's name is not displayed in the incoming call history, and only the telephone number and e-mail address are recorded.

  Furthermore, when a call is received from a user registered in the phone book, the name and phone number of the user are displayed on the display unit during the incoming call. When a call is received from a user registered in this phone book, the name of the user is not displayed during the incoming call, but only the phone number is displayed. .

  Japanese Patent Laying-Open No. 2002-223289 (Patent Document 1) discloses a “method for maintaining the confidentiality of stored contents that can be confirmed by a known operation” that can maintain the confidentiality of a shortened registered telephone number. This secret keeping method performs a pre-operation for speed dial registration by depressing a function key and an abbreviated key, and inputs a 2-digit abbreviated number. Next, when the other party telephone number is inputted, the inputted other party telephone number is displayed on the display unit in comparison with the abbreviated number. In this state, the user presses the function key after pressing the shortened key a predetermined number of times at an arbitrary timing. As a result, the speed dial corresponding to the entered telephone number is registered for confidentiality.

  When making a call using this abbreviated registration number, the abbreviated key is pressed at the same timing as the secret registration. As a result, communication with the communication partner of the speed dial that is kept secret is possible.

  This confidentiality method can maintain confidentiality while keeping the abbreviated registration number stored in the phone, so the stored contents that you do not want to be known to others can be erased or overwritten with other information By doing so, it is possible to prevent inconvenience that information stored in the telephone cannot be used.

  Also, if the abbreviated key is not pressed at the same timing as the confidentiality registration, communication with the communication partner of the speed dial registered for confidentiality is not possible. In addition, confidentiality can be maintained even if a single telephone is used by multiple persons.

JP 2002-223289 A (pages 3 to 4: FIG. 1)

  However, the above-described secret function is set for the entire telephone directory, the entire address book, the entire schedule book, or all electronic mails transmitted and received. Once the secret setting is made, the phone book, the address book, etc. cannot be displayed unless this setting is canceled. For this reason, for example, a user who frequently browses an e-mail needs to frequently perform a secret setting operation and a secret setting release operation on the received e-mail, and this is very troublesome although it is necessary to keep secret of personal information. There was a problem that forced us to operate. If the user forgets to set the secret function, the personal information such as the telephone directory and the address book can be easily displayed.

  In addition, the above-mentioned secret function can be used only when a voice call is received, even if the calling user is registered in the phone book, the user's name is not displayed during the incoming call, and only the phone number is displayed. In the incoming call history, only the phone number is recorded without recording the name of the caller. In this way, only the phone number is displayed or recorded in the incoming call history. There is a problem that a third party notices that there is an incoming call from the incoming call history.

  In other words, from the viewpoint of strictly protecting personal information, it is preferable not to let third parties know that this voice call or mail has arrived. It is preferable not to perform an operation for notifying the user of an incoming call, such as ringing a ringtone or a vibrator and blinking (lighting) an incoming light emitting unit (incoming LED).

  Further, the secret function described above displays a password input screen when a secret telephone set, address book or the like is displayed. The fact that this password entry screen is displayed means that confidential information is stored in the phone book, address book, etc. that are designated for display, so a third party can easily guess this. be able to. For this reason, displaying such a password input screen is not preferable from the viewpoint of strictly protecting the personal information.

5). When displaying an email from a protected user, first display an alternative email and display it when the correct password is entered,
6). The substitute email displayed instead of the email from the protected user is displayed by changing the style every predetermined time or every predetermined number of times,
7). By allowing the user to register the desired style as an alternative email,
Only the information related to the protected user can be strictly protected individually.

In the case of the mobile phone of this embodiment,
8). By replacing the substitute mail with a flag and storing it in the RAM 9, when the manufacturer or the like verifies the information such as the electronic mail stored in the RAM 9, it is an actually received electronic mail. It is possible to determine whether the email is a substitute email.

[Registration of protected users]
First, when registering the protected user, the user of the mobile phone performs a predetermined protected user registration operation via the operation unit 5. When the control unit 12 detects the registration operation of the protected user, the control unit 12 reads out the telephone book stored in the RAM 9 and controls the display on the display unit 6.

The user operates the operation unit 5 to
1. Select a user to be registered as a protected user from the phone book displayed on the display unit 6,
2. Set a time period to release protection for this protected user,
3. Set a verification password to be input when browsing emails received from or sent to this protected user,
4). An alternative mail to be displayed or displayed instead of the e-mail received from the protected user or transmitted to the protected user is selected or input.

  That is, the mobile phone of this embodiment is configured not to perform an incoming call operation except for a designated time zone even when a telephone call is received from a user designated as a protected user. Similarly, even when an e-mail is received from a user designated as a protected user, the incoming operation is not performed outside the designated time period, and the mail incoming history and incoming mail text are not displayed. Furthermore, even when a telephone call or a mail transmission is performed to a user designated as a protected user, the telephone call history, the mail transmission history, and the transmitted mail text are not displayed outside the designated time zone.

  For this reason, when the user selects a user to be registered as a protected user from the telephone directory, the time period for releasing the protection is set to, for example, “every day from 23:00 to 24:00” or “every Sunday from 15:00 to 17:00”. And so on.

  Further, in the case of the mobile phone of this embodiment, when browsing an email received from a protected user or transmitted to the protected user, an alternative email is first displayed. By inputting the registered password, an e-mail received from or sent to the protected user is displayed instead of the substitute mail.

  For this reason, the user sets a verification password for verification with a password input when browsing an e-mail received from the protected user or transmitted to the protected user.

  Further, in the case of the mobile phone of this embodiment, as alternative mails displayed in place of an email received from a protected user or transmitted to the protected user, a plurality of alternative mails each having different sentences are used. Is stored in the RAM 9, and a plurality of substitute mails formed by the user inputting a sentence can be registered. For this reason, the user selects a desired substitute mail from the substitute mails stored in the RAM 9 or registers a substitute mail formed by inputting a sentence.

  When a user to be registered as a protected user is selected, the control unit 12 detects a user information storage area in which user information of the user designated as the protected user is stored from the telephone directory storage area of the RAM 9. Controls storage of information indicating the time period for canceling the protection (protection cancellation information), a verification password, and information indicating an alternative mail selected by the user (or an alternative mail input by the user) in the information storage area At the same time, a flag (protected user information) indicating that the protection setting is made for the user information in the user information storage area is set for the user information storage area. Thereby, registration of a protection user is completed.

  Note that when an operation for canceling registration as a protected user is performed via the operation unit 5, the control unit 12 sets the flag set for the user information storage area as a protected user. Cancel the registration.

  In this way, the user of the mobile phone individually registers a protected user for a desired user. Thereafter, the confidentiality of the information regarding the protected user is strictly protected based on the information protection program stored in the ROM 8.

[Hidden operation of protected user when displaying phone book]
Next, the user information of the user who has been registered as a protected user is not displayed when the phone book is displayed. The flowchart of FIG. 2 shows the flow of the phone book display operation of the control unit 12.

  First, the user designates display of the phone book by operating the operation unit 5. When the control unit 12 detects the telephone book designation operation, the control unit 12 starts the process shown in the flowchart of FIG. 2 based on the information protection program stored in the ROM 8.

  In step S1, the control unit 12 detects the operation state of the operation unit 5 to determine whether or not the user has instructed the end of the phone book display operation, and the user ends the phone book display operation. If it is determined that no instruction has been given, the process proceeds to step S2.

  In step S2, the control unit 12 detects the presence / absence of a flag (= protected user information) for each user information stored in the telephone directory of the RAM 9, thereby detecting the protection setting user and the protection setting information. Determine who has not been made. In addition, the control unit 12 detects the protection release information (information indicating a time zone for releasing the protection) stored as the user information of each user for which protection is set, and is counted by the RTC 7. The current time is detected and compared. And the user whose present time is the time slot | zone which cancels protection is detected among the users with protection setting.

  Next, the control unit 12 stores the user information of “users who are not protected” and “users whose protection is set but the current time is a time zone for releasing protection” Each is read out from the book storage area, and these are displayed on the display unit 6 in step S3. On the other hand, user information of a user who has been set for protection and whose current time is not in the time zone for releasing protection is not displayed in step S4.

  The control part 12 will return a process to step S1, if this display operation is performed. In step S1, the phone book display process is repeated until it is determined that the user has instructed the end of the phone book display operation.

  As described above, when the display of the phone book is designated, the user information of the user for whom protection is set is not displayed except for the preset time zone for canceling the protection. When the user information is displayed, it is possible to prevent the inconvenience of displaying the user information of the user for whom the protection setting is made, and it is possible to strictly protect the user information of the user for which the protection setting is made.

[Operation when incoming calls and mails]
Next, in the case of the mobile phone according to this embodiment, even if there is an incoming call or an incoming mail from a user who has been registered as a protected user, the incoming call operation is not performed except during a time period in which protection cancellation is specified. It has become. The flow chart of FIG. 3 shows the flow of operation of the mobile phone when receiving a telephone call or mail. When detecting the incoming call or e-mail, the control unit 12 starts the flowchart shown in FIG. 3 based on the information protection program stored in the ROM 8.

  In step S <b> 11, the control unit 12 determines whether or not the telephone number or e-mail address of the user who is the transmission source included in the incoming signal is stored in the telephone book of the RAM 9. If the telephone number or e-mail address of the user who is the sender is not stored in the telephone directory, the control unit 12 proceeds to step S15 and displays the telephone number or e-mail address of the user who is the sender. In addition to controlling the display on the unit 6, the incoming call control is performed such that the incoming call sound and the vibrator are sounded and the incoming LED is blinked (lit) to inform the user of the incoming call or e-mail. The process ends.

  On the other hand, when the telephone number or e-mail address of the user who is the transmission source is stored in the telephone directory, the control unit 12 advances the process to step S12, and for the currently incoming user. It is determined whether or not the above-described protection setting has been made.

  In the case of an incoming call from a user for whom protection is set, the control unit 12 advances the processing to step S13 and is counted by the RTC 7 with information indicating a time zone for releasing the protection set for the user. It is determined whether or not it is a time zone that can be displayed by comparing with the information indicating the current time.

  If it is not the time zone that can be displayed, the control unit 12 advances the process to step S16, and stores the incoming call history of this protected user in the incoming call history storage area or the incoming mail history storage area of the RAM 9. Recording is completed, and the process shown in the flowchart of FIG. As a result, no incoming call operation is performed unless a telephone number or the like is displayed for an incoming call from a user whose protection is set. As will be described later with reference to the flowchart of FIG. 4, this incoming call history is also not displayed except for the protection cancellation time zone specified by the user.

  Next, when it is determined in step S12 that the call is from a user who is not set for protection, and in step S13, the call is received from a user for which protection is set, but the protection is canceled. If it is determined that the current time zone is present, the control unit 12 advances the process to step S14, and the incoming caller name stored in the phone book of the RAM 9 together with the incoming phone number or e-mail address. Is displayed on the display unit 6, and the incoming call control is performed such that the ringing tone and the vibrator are sounded and the incoming LED is blinked (lighted) to inform the user of the incoming call or e-mail. The process shown in FIG.

  As a result, when there is an incoming call from a user who has not been set for protection, and when the incoming call is from a user who has been set for protection, but during the time period when the protection is released, the display for normal incoming calls is displayed. Operation and incoming call operation are performed.

[Displaying call / mail history]
Next, when there is an incoming call or an incoming mail from a user who has been registered as a protected user, and when an outgoing call or an outgoing mail is made to a user who has been registered as a protected user, the control unit 12 makes an A mail outgoing / incoming history is formed and stored in the RAM 9 and controlled, but the outgoing and incoming call histories of the telephone and mail are also not displayed except during the time period when the protection is canceled.

  The flowchart of FIG. 4 shows the flow of the display operation of the call and e-mail history of the mobile phone. When the user displays the outgoing / incoming history, the user designates the display of the outgoing / incoming history via the operation unit 5, but the control unit 12 detects the display designation operation of the outgoing / incoming history, The flowchart shown in FIG. 4 is started based on the information protection program stored in the ROM 8.

  In step S21, the control unit 12 retrieves each outgoing / incoming call history stored in each outgoing / incoming storage area of the RAM 9, so that the user who is set to be protected in the outgoing / incoming history specified by the user is displayed. It is determined whether the outgoing / incoming call history corresponding to is included.

  If the outgoing / incoming history corresponding to the protected user is not included, the control unit 12 advances the processing to step S24, and controls the display unit 6 to display the outgoing / incoming history specified by the user as it is. Then, the process shown in the flowchart of FIG.

  On the other hand, when the outgoing / incoming history corresponding to the user set for protection is included, the control unit 12 advances the process to step S22 to detect the protection release information of the user set for protection. By comparing with the current time counted by the RTC 7, it is determined whether or not it is the protection cancellation time zone currently specified by the user set for protection.

  When it is determined that it is the time period for canceling the protection, the outgoing / incoming call history corresponding to the user set for protection is added to the outgoing / incoming call history designated for display by the user, and the display unit 6 controls the display. The process shown in the flowchart of FIG. 4 ends.

  If it is determined that it is not the protection cancellation time zone, display control is performed on the display unit 6 except for the outgoing / incoming history corresponding to the user set to be protected from the outgoing / incoming history designated for display by the user, The process shown in the flowchart of FIG. 4 ends.

  This makes it possible to hide the outgoing / incoming history corresponding to the protection-set user, except for the protection cancellation time zone specified by the user, and strictly protects the user information of the protection-set user. Can be protected.

[Incoming call operation]
Next, in the case of the mobile phone according to this embodiment, when there is an incoming call, when the off-hook operation is not performed during the call, and when an e-mail is received, the control unit 12 may, for example, “(call) incoming”, “ The display unit 6 controls the display of the incoming message “with incoming mail”. However, when there is an incoming call or incoming mail from a user who is set to be protected, this display is performed except for the time period when the protection is canceled. Incoming calls are not displayed.

  The flow chart of FIG. 5 shows the flow of the incoming call display operation of the mobile phone when a call and an e-mail are received. This flowchart starts when there is an incoming call and no off-hook operation is performed during the call and when an e-mail is received.

  In step S <b> 31, the control unit 12 determines whether or not the telephone number or e-mail address of the user who is the transmission source included in the incoming call signal is stored in the telephone directory of the RAM 9. If the telephone number or e-mail address of the user who is the transmission source is not stored in the telephone directory, the control unit 12 advances the process to step S34, and indicates that “(phone) incoming” and “mail incoming”. Is displayed on the display unit 6 and the processing shown in the flowchart of FIG. 5 is terminated.

  On the other hand, when the telephone number or e-mail address of the user who is the transmission source is stored in the telephone directory, the control unit 12 advances the processing to step S32 and sets the above-described protection setting for the incoming user. It is determined whether or not.

  In the case of an incoming call from a user who has not been set for protection, the control unit 12 advances the process to step S34, and controls the display unit 6 to display an incoming call display of “(call) incoming” and “mail incoming”. Then, the process shown in the flowchart of FIG.

  If the incoming call is from a user for whom protection is set, the control unit 12 advances the processing to step S33, and information indicating the time zone for releasing the protection set for the user and the RTC 7 By comparing with the information indicating the current time being counted, it is determined whether or not it is a time zone that may be displayed.

  If it is a time zone that can be displayed, the control unit 12 advances the process to step S34, and controls the display unit 6 to control display of incoming calls such as “(phone) incoming” and “mail incoming”. The process shown in the flowchart of FIG.

  If it is a time zone to be hidden, the control unit 12 advances the processing to step S35, and hides the incoming call display of “(phone) incoming” and “mail incoming”. The process shown in FIG.

  As a result, it is possible to hide the display of incoming calls such as “(call) incoming” and “mail incoming” except during the time period when the protection is canceled. Can be strictly protected.

[Display of incoming and outgoing mail]
Next, in the mobile phone of this embodiment, when display of an incoming / outgoing e-mail is specified in a time zone other than the time zone for releasing the protection, an e-mail received from a user set for protection, Or display the title of the substitute email instead of the subject of the email sent to the protected user, and when the user points to the subject of the substitute email and enters the regular password for the first time The body of an e-mail received from a user set for protection or the body of an e-mail sent to a user set for protection is displayed.

  The flowchart of FIG. 6 shows the first half of the outgoing / incoming mail display operation, and the flowchart of FIG. 7 shows the second half of the outgoing / incoming mail display operation. When the user designates display of outgoing / incoming mail, the user first operates the operation unit 5 to designate display of a list of outgoing / incoming mail titles. This series of flowcharts is performed by the control unit 12. It starts by detecting an operation that specifies the display of a list of outgoing and incoming mail titles.

  In step S41, the control unit 12 reads out a list of incoming mail titles or a list of outgoing mail titles designated for display by the user from the RAM 9, and selects a desired title from the list of titles. Display control is performed on the display unit 6 together with the cursor.

  Note that if the incoming / outgoing e-mail includes an e-mail corresponding to the user who is set to be protected, the control unit 12 will replace the title of the e-mail corresponding to the user set to be protected. The title of the substitute mail selected or input by the user is included in the list and displayed.

  Next, the user moves the cursor via the operation unit 5 to select the title of the electronic mail desired to be displayed. In step S42, the control unit 12 performs the title selection operation. Determine whether it was done.

  If it is determined that the title selection operation has been performed, the control unit 12 advances the process to step S43 to determine whether or not the alternative mail title has been selected by this selection operation. If it is determined that the title of the email other than the substitute email is selected, the title of the email other than the substitute email is not an outgoing / incoming email corresponding to the protected user. Advances the process to step S50, reads the mail text from the RAM 9, controls display on the display unit 6, and advances the process to step S49 shown in FIG.

  On the other hand, the fact that the title of the substitute mail is displayed means that the control unit 12 indicates that there is an incoming / outgoing mail of the user for which the above protection setting is made (the title of the substitute mail is the control. Only the user of the unit 12 and the mobile phone can recognize it). Therefore, in step S44, the control unit 12 detects the outgoing / incoming mail corresponding to the selected substitute mail from the RAM 9, and cancels the protection setting that is set for the user of the detected incoming / outgoing mail. Detect time zone. Then, whether this protection setting cancellation time zone and the information indicating the current time counted by the RTC 7 are compared, and it is a time zone in which a protected user's outgoing / incoming mail corresponding to this alternative email may be displayed. Determine whether or not.

  If it is determined that it is a time zone in which the outgoing / incoming mail of the user set to be protected may be displayed, the control unit 12 proceeds with the process to step S48 in the flowchart of FIG. 7, and the protection corresponding to the substitute mail is set. The text of the outgoing / incoming mail of the user is read from the RAM 9 and displayed on the display unit 6.

  On the other hand, if it is determined that it is a time period during which the user's outgoing / incoming mail is set to be protected, the control unit 12 proceeds to step S45 to determine whether or not a password input operation has been performed. If a substitute mail display operation is detected without detecting a password input operation, the control unit 12 advances the process to step S51, reads the substitute mail selected or input by the user from the RAM 9, Display control is performed on the display unit 6 and the process proceeds to step S49 in the flowchart of FIG. Thereby, instead of the user's outgoing / incoming mail with protection setting, for example, an unobstructed sentence such as “Tomorrow's meeting will be held in the A meeting room from 10:00” will be displayed.

  Note that the control unit 12 stores the number of times that the substitute mail has been displayed and the display time in the past. For example, the sender of the substitute mail to be displayed, the outgoing / incoming time, and the content of the text are displayed every predetermined time or every predetermined number of times. change. Thereby, it is possible to prevent the inconvenience that the third party notices that the currently displayed electronic mail is the substitute mail by displaying the substitute mail having the same content continuously.

  The substitute mail is stored in the RAM 9 with a flag. For this reason, for example, when the manufacturer or the like verifies information such as an e-mail stored in the RAM 9, it can be determined based on this flag whether it is an actually received e-mail or an alternative e-mail. can do.

  On the other hand, if a password input operation is detected in step S45, the control unit 12 proceeds to step S46 in the flowchart of FIG. 7 to verify the input password and a verification password stored in the RAM 9. Plan.

  More specifically, in the case of the mobile phone of this embodiment, even when the title of the substitute mail is selected, a message prompting the input of a password or the like is not displayed. This is because, by displaying such a message, a third party recognizes that the display of the title of the substitute mail is a confidential display. Therefore, the user inputs the password voluntarily. Specifically, the user performs a password input operation after moving (pointing) the cursor to the display position of the substitute mail title. As a result, the control unit 12 advances the process to step S <b> 6, and collates the input password with the verification password stored in the RAM 9.

  Next, in step S47, the control unit 12 determines whether or not both passwords match, that is, whether or not the user has been authenticated. If both passwords do not match and the user authentication cannot be performed as a legitimate user, the control unit 12 advances the process to step S51 in the flowchart of FIG. 6 and displays the text of the substitute mail described above on the display unit. 6 to display control.

  On the other hand, when both passwords match, user authentication can be performed as a regular user, and in step S44 of the flowchart of FIG. If it is determined that the time period is acceptable, the control unit 12 reads out the incoming / outgoing mail of the protected user corresponding to the substitute mail from the RAM 9 and controls the display unit 6 to display it in step S48. As a result, the outgoing and incoming mails of the protected user are displayed only within the time zone for which protection is set and only when a regular password is entered.

  Next, the control unit 12 advances the process to step S49, determines whether or not the display end of the displayed e-mail is specified by the user via the operation unit 5, and detects the display end specification. Then, the processing of the series of flowcharts shown in FIGS. 6 and 7 ends.
