<Embodiment>
<Device Configuration> FIG. 1 is a block diagram showing an electrical configuration of a mobile phone 1 as an embodiment of a mobile terminal device according to the present invention. As shown in FIG. 1, a mobile phone 1 includes a wireless processing unit 101, a touch sensor 102 having a scanner function and a touch panel 100 including an LCD (Liquid Crystal Display) panel 103, a system control unit 104, an audio A processing unit 105 and a memory 106 are provided.

  The wireless processing unit 101 receives a signal from a mobile phone different from the mobile phone 1 or a communication device such as a server device connected to the Internet by the antenna AT, and performs amplification processing and down-conversion on the received signal. And performing an up-conversion or amplification process on the transmission signal generated by the system control unit, and the processed transmission signal is separated from the mobile phone 1 through the antenna AT. Send to a telephone or a communication device connected to the Internet.

  The touch panel 100 is controlled by the system control unit 104 to display various information such as icons and characters for starting the application program on the display surface. The touch panel 100 detects an operation by a user's finger or the like on the display surface by the touch sensor 102 and outputs the operation to the system control unit 104, and also detects a fingerprint of the user's finger that has touched the display surface to Output.

The system control unit 104 includes a CPU (Central Processing Unit) (not shown) and the like, and comprehensively manages the operation of the mobile phone 1 by controlling other components of the mobile phone 1.

  The voice processing unit 105 converts voice data from the system control unit 105 into voice and outputs the voice to the outside. The voice processing unit 105 converts voice inputted from the outside into voice data and sends the voice data to the system control unit 105. An input unit (not shown) for outputting is provided.

  The memory 106 includes a ROM, a RAM, and the like. Various functions of the system control unit 104 are realized by the CPU executing various programs in the memory 106.

  The memory 106 stores a plurality of application programs (hereinafter simply referred to as “applications”) in addition to the OS program. Examples of applications include a call program, an e-mail program, a browser, a navigation program, a map display program, a schedule management program, and an address book management program.

    <Security Management Operation> Next, the security management operation of the application of the mobile phone 1 will be described with reference to FIGS.

  First, the confidential management operation in the main menu process will be described with reference to the flowchart shown in FIG.

  When the mobile phone 1 is in the sleep state in the main menu display mode (step S1), the display is turned off to save power consumption. However, the touch panel 100 is touched with a finger or the like to return from the sleep state (step S1). S2), the fingerprint of the finger is read by the touch sensor 102 (step S3).

  Here, the fingerprint data of the administrator (authorized person) of the mobile phone 1 is stored in advance in the memory 106 or the like, and the stored fingerprint data is collated with the fingerprint data read by the touch sensor 102 ( Step S3).

  If the stored fingerprint data matches the read fingerprint data, it is determined that the user is an administrator (step S4), the process proceeds to step S5, the flag is set to 0, and the process proceeds to step S7. move on. On the other hand, if the fingerprint data does not match, it is determined that the person is not the administrator (third person) (step S4), the process proceeds to step S6, the flag is set to 1, and the process proceeds to step S7. If it is determined in step S1 that the mobile phone 1 is not in the sleep state, the process starts from the determination in step S7.

  In step S7, it is determined whether the flag is 0 or 1. If the flag is 0, the process proceeds to step S8, and the presence or absence of usage history information by a third party is confirmed. On the other hand, if the flag is determined to be 1 in step S7, a menu screen for a third party is displayed in step S13.

  Here, a menu screen for a third party is shown in FIG. The menu screen for the third party is displayed by distinguishing a startable application from a plurality of application displays and an application that is security-locked and cannot be started. It is displayed in monotone (applications C and D, such as e-mail program and schedule management program), and the application cannot be started even if the application display is touched. On the other hand, applications that can be started without security lock being set (applications A and B, such as browser programs and navigation programs) are displayed in color, and by touching the application display, The application can be activated through the processing after step S10.

  If it is determined in step S8 that there is history information, the process proceeds to step S14 to check the history information. By confirming the history information, the operation parameters (setting information) can be automatically restored. This process will be described later using the flowchart shown in FIG. 2 and FIG. 5 are connected by the symbol A. On the other hand, if there is no history information, the process proceeds to step S9 to display an administrator menu screen.

  Here, FIG. 4 shows a menu screen for the administrator. The menu screen for the administrator is an application display in which a plurality of application displays can be activated, and any administrator can activate any application through the processing from step S10 onward.

  When the touch sensor 102 (FIG. 1) detects that the administrator and the third party touch the application display (activatable) with a finger or the like (step S10), the fingerprint of the finger is read by the touch sensor 102. (Step S11).

  The owner of the fingerprint data obtained here, that is, the current user (executor) of the mobile phone 1 is collated with the determination result of the flag determined in step S7 (step S12), and the two match. If so, the application selected as having execution authority is executed, and if the two do not match, the operation after step S7 is repeated assuming that there is no execution authority.

Here, when the user of the mobile phone 1 does not match the flag determination result, the flag is determined to be 0 in step S7, that is, the administrator touches the menu screen and the menu screen for the administrator is displayed. After being displayed, if for some reason the third party has the mobile phone 1, or the flag is determined to be 1 in step S7, that is, the third party touches the menu screen and It is conceivable that the administrator has the mobile phone 1 after the menu screen for three parties is displayed. In such a case, the display of the menu screen for the third party or the return process to the administrator is performed by repeating the operations in step S7 and subsequent steps.

  Next, a security management operation when executing an application for which a security lock is set will be described using the flowchart shown in FIG.

  When the execution of the application with the security lock set is started through the main menu process described with reference to FIG. 2 (step S21), an operation menu for operating the executed application is first displayed (step S22). ).

  When an administrator or a third party touches a predetermined operation in the operation menu with a finger or the like (step S23), the fingerprint of the finger is read by the touch sensor 102 and fingerprint data stored in advance in the memory 106 or the like. And fingerprint data read by the touch sensor 102 are collated (step S24).

  If the stored fingerprint data matches the read fingerprint data, it is determined that the user is an administrator (step S25), and the process proceeds to step S26 to execute the selected operation. On the other hand, if the fingerprint data does not match the read fingerprint data, it is determined that the person is a third party and the process proceeds to step S28.

  In step S28, setting information necessary for restarting the operation so as to be able to return to the operation state of the application at that time, for example, various parameters are saved, and then the flag is set to 1 in step S29. Record that the performer is a third party.

  After that, in step S30, an operation history about what operation the third person who is the executor has executed for what application is recorded in the memory 106 (FIG. 1) and the application is forcibly terminated. (Step S31).

  After the execution of the operation selected in step S26 is started, the operations in and after step S22 are repeated until the end of the application is confirmed in step S27. When the end of the application is confirmed, the main shown in FIG. Return to menu processing.

  If it is determined in step S8 shown in FIG. 2 that there is history information, the process proceeds to step S14 to check the history information, and thereafter, in step S32, the operation parameters are automatically restored, and step S22 is performed. The following operation is repeated.

  As described above, even when the application is executed, the fingerprint data is collated at any time, so that when a third party has the mobile phone 1 in the middle of executing the application started by the administrator, Even if a third party intends to operate an application started by an administrator due to intention or mistake, fingerprint data is collated every time a panel touch necessary for the operation is performed, and it is found that the operation is performed by the third party. If the application is forcibly terminated, confidentiality can be increased.

  As described above, the following cases are assumed as cases where fingerprint data mismatch occurs during the execution of the application started by the administrator.

<Case 1> An incoming call is received while the administrator is executing an application (for example, applications C and D in FIG. 3) that is locked by security and cannot be started by anyone other than the administrator. When a call is switched to a third party who is together, when the call ends, the execution of the active application is resumed. When the application is resumed, the third party remains with the mobile phone 1 held by the third party. If the application is operated intentionally or by mistake, fingerprint data mismatch will occur.

    <Case 2> When a user stands up while the mobile phone 1 is placed while the administrator is executing an application that is locked by security and cannot be started by anyone other than the administrator, the malicious third party When an application operation is performed, fingerprint data mismatch occurs.

    <Case 3> When the mobile phone 1 is lent to a third party to use an application that can be activated even by a third party such as a camera or a game, an application that is security-locked and cannot be activated by anyone other than the administrator. When the administrator lends the device while it is activated, if the third party intentionally or mistakenly operates the application, fingerprint data mismatch will occur.

  When the application is forcibly terminated corresponding to the above case, the process returns to the main menu process shown in FIG. 2, and after steps S1 to S4 and S6, the flag is checked in step S7 to determine the third party. In such a case, a menu for a third party is displayed in step S13, and the application with the security lock set cannot be started.

  Thereafter, when the administrator again possesses the mobile phone 1, in step S12, the current user of the mobile phone 1 and the determination result of the flag determined in step S7 do not match, and the process returns to step S7. It will be. In this case, in the flag check in step S7, it is determined that the user is an administrator. In step S8, the presence / absence of history information is confirmed. If there is history information, the history information is confirmed in step S14. By confirming the history information, the operation parameters are automatically restored (FIG. 5, step S32), and the operation selected in the operation menu is executed through the operations after step S22 (FIG. 5) to restart the application.

  As described above, when the application started by the administrator is forcibly terminated by the use of the third party, the usage history of the third party can be confirmed, which is caused by the operation performed by the third party. Disadvantages can be prevented or reduced.

  Even if the application started by the administrator is forcibly terminated by the use of a third party, when the mobile phone 1 returns to the administrator, the application can be read by reading various stored parameters. Since it can be resumed from the interrupted state, it is possible to save the administrator from setting various parameters again.

    <Modification> In the embodiment of the portable terminal device according to the present invention described above, a configuration is adopted in which a security lock is set for an application. When a third party uses an application started by a person, the security control is performed by forcibly terminating the application.

  However, in security management, setting security for a folder in the application may be more convenient than setting security for the application.

  For example, a movie or camera application is often not used exclusively by an administrator, but is often handed over to a third party for photographing. Therefore, if a security lock is set for a movie or camera application, the third party cannot use it, which is inconvenient. However, if a third party can also start without setting a security lock, the third party can view a movie or camera folder, which may be inconvenient for the administrator.

  Therefore, the folder for movies and cameras is divided into a public folder that can be opened by a third party and a private folder that is set by a security lock that cannot be opened by the third party, and security management is performed on the folder. It is good also as a structure.

  Hereinafter, the confidentiality management operation for the folder will be described with reference to the flowcharts shown in FIGS.

  In the flowchart shown in FIG. 6, when the mobile phone 1 is in the sleep state in the main menu display mode (step S <b> 41), the display is turned off to save power consumption, but by touching the touch panel 100 with a finger or the like. Returning from the sleep state (step S42), the fingerprint of the finger is read by the touch sensor 102 (step S43).

  If the stored fingerprint data matches the read fingerprint data, it is determined that the user is an administrator (step S44), the process proceeds to step S45, the flag is set to 0, and the process proceeds to step S7. move on. On the other hand, if the fingerprint data does not match, it is determined that the person is not the administrator (third person) (step S44), the process proceeds to step S46, the flag is set to 1, and the process proceeds to step S47.

  In step S47, it is determined whether the flag is 0 or 1. If the flag is 0, the process proceeds to step S48, where the presence or absence of usage history information by a third party is confirmed. On the other hand, if the flag is determined to be 1 in step S47, a third party folder screen is displayed in step S53. In this screen, among the plurality of folder displays, a folder that can be referred to and a folder that cannot be referred to due to security lock are displayed separately. By touching the referable folder display, the files in the folder can be played back through the processing from step S50.

  If it is determined in step S48 that there is history information, the process proceeds to step S54 to check the history information. By confirming the history information, the operation parameters can be automatically restored. 6 and 7 are connected by the symbol A.

  On the other hand, if there is no history information, the process proceeds to step S49 to display an administrator folder screen.

  Here, the administrator's folder screen is a folder display in which a plurality of folder displays can be referred to, and the administrator can refer to any folder through the processing from step S50 onward. .

  When the touch sensor 102 (FIG. 1) detects that the administrator and the third party touch the folder display (which can be referred to) with fingers or the like (step S50), the fingerprint of the finger is read by the touch sensor 102. (Step S51).

  The owner of the fingerprint data obtained here, that is, the current user (executor) of the mobile phone 1 is collated with the determination result of the flag determined in step S47 (step S52). If so, the moving image file included in the folder selected as having the execution authority is played back, and if they do not match, the operation after step S47 is repeated assuming that there is no execution authority.

  Next, the confidentiality management operation during file reproduction will be described using the flowchart shown in FIG.

  When the file in the folder in which the security lock is set is played through the main menu processing described with reference to FIG. 6 (step S61), operation keys such as stop, fast forward, and fast reverse are displayed on the playback screen ( Step S62).

  When an administrator or a third party touches an operation key with a finger or the like for operation (step S63), the fingerprint of the finger is read by the touch sensor 102 and touched with fingerprint data stored in advance in the memory 106 or the like. Collation with the fingerprint data read by the sensor 102 is performed (step S64).

  If the stored fingerprint data matches the read fingerprint data, it is determined that the user is an administrator (step S65), and the operation proceeds to step S66 to execute the operation of the selected operation key. On the other hand, if the fingerprint data does not match the read fingerprint data, it is determined that the person is a third party and the process proceeds to step S68.

  In step S68, various parameters are saved so that the file playback state at that time can be restored, and then the flag is set to 1 in step S69 to record that the performer is a third party. .

  After that, in step S70, an operation history about what operation is performed on which file in which folder by the third person who is the executor is recorded in the memory 106 (FIG. 1) or the like, and the file is reproduced. Is forcibly terminated (step S71).

  After starting the operation key operation in step S66, the operations in step S62 and subsequent steps are repeated until the reproduction is finished in step S67. When the completion of the reproduction is confirmed, the process returns to the main menu process shown in FIG. .

  If it is determined in step S48 shown in FIG. 6 that there is history information, the process proceeds to step S54, where the history information is confirmed, and thereafter, in step S72, the operation parameters are automatically restored, and step S62 is performed. The following operation is repeated.

  As described above, a security lock is set on the folder, and the fingerprint data is collated even when the file is played, so that the third party possesses the mobile phone 1 during the execution of the file selected by the administrator. When the third party intentionally or mistakenly tries to operate the file being played back by the third party, the fingerprint data is collated every time the panel touch necessary for the operation is performed. If it is determined that the operation is performed by the user, the reproduction is forcibly terminated, so that confidentiality can be improved.

  More specifically, when the administrator starts a movie application and plays a file in a private folder, if the third party asks to shoot a movie, the third party Since the reproduction of the file is forcibly terminated when the touch is made, a third party cannot see the file in the private folder being reproduced. Furthermore, if a private folder is open, the third party cannot see the private folder if it is also terminated.

  In addition, when a file in a private folder that has been played back by the administrator is forcibly terminated by a third party, the usage history of the third party can be confirmed. It is possible to prevent or reduce the disadvantages caused by.

Also, even if the file in the private folder that the administrator is playing is forcibly terminated by the use of a third party, when the mobile phone 1 returns to the administrator, various stored parameters are read out. Thus, since the reproduction can be resumed from the interrupted state, the administrator can view the video from the middle of the reference, and can save the trouble of fast forward and fast reverse.

  In the above description, an example of setting a security lock on a folder using a movie application as an example is shown, but the present invention is not limited to this, and a security lock is set on a folder of a camera application. Alternatively, a security lock may be set for the music folder in the music player application. Further, a security lock may be set not on the folder but on the file itself.

  In short, for applications that do not have information acquired simply by looking at folder names and file names, it is more convenient for users to set security locks on folders and files rather than setting security locks on the applications themselves. Will be better.

  On the other hand, for applications where information is acquired just by looking, such as an e-mail address book, a security lock is set on the application itself, a function for setting a security lock on the application, and a security lock on folders and files. By using it together with the function to set the security, confidentiality management becomes possible.

  According to the above-described embodiment and its modification, it is possible to prevent a third party without use authority from using a specific function that is a security target. Can also be solved.

  In other words, in the configuration disclosed in Patent Document 1, fingerprint verification is performed by touching the touch panel, and security of a specific function is released if the fingerprint is authenticated by a preset authorized person. Once security is released, even a third party without the right to use can freely use the specific function, and there is a problem that it is not known what operation the third party has performed. However, according to the embodiment and the modification thereof, it is also possible to acquire the operation history of a third party without the use authority.
