Information processing device and method

[0001] The present invention relates to an information processing device and method.

[0002] In information processing devices such as smartphones and tablets, a home screen on which icons of applications installed on the information processing device are arranged is displayed on the display unit, and the user can use an application by selecting the application to use from this home screen.

[0003] In such information processing devices, important applications such as banking applications are also displayed on the home screen, so if someone were to peek at the home screen or if the information processing device were stolen, there is a risk that the existence of the important applications would become known to others.

[0004] Patent document 1 describes a technology that can impose restrictions on the operation of a terminal device after the user has released the lock state, depending on the user, by determining the degree of match between the input unlock information and correct answer information, and determining the content of the restrictions on the operation of the terminal device after release of the lock based on the degree of match.

[0006] However, in the terminal device described in Patent Document 1, once the terminal device is unlocked, it can be used with the determined restrictions. Therefore, if the information processing device is stolen while unlocked or if the home screen is peeked at, it is not possible to prevent the existence of important applications from being discovered by others.

[0007] Therefore, an object of the present invention is to provide a technique that can limit applications displayed on the home screen after unlocking.

[0008] In order to solve the above problem, one representative information processing device of the present invention is an information processing device that displays application icons on a display unit, and is equipped with a control unit that accepts an operation to call up a first authentication screen, and when the operation to call up the first authentication screen is accepted, displays the first authentication screen on the display unit, accepts first authentication information on the first authentication screen, performs a first authentication using the first authentication information, and when the first authentication is successful, transitions to a normal operating state in which part of the icon is displayed on the display unit, and in the normal operating state, accepts an operation to call up a second authentication screen, and when the operation to call up the second authentication screen is accepted, displays the second authentication screen on the display unit, accepts second authentication information on the second authentication screen, performs a second authentication using the second authentication information, and when the second authentication is successful, transitions to an extended operating state in which the entire icon is displayed on the display unit.

[0009] According to the present invention, it is possible to limit the applications that are displayed on the home screen after unlocking.

Furthermore, components not shown, such as a digital broadcast reception function and an electronic money payment function, may also be added. [Exemplary Appearance of Information Processing Device] FIG. 2 is an external view showing an example of the appearance of the information processing device 100. This figure illustrates an example of a front (surface) view (A) and a rear (back) view (B) of the information processing device 100 when the information processing device 100 is a smartphone or the like, and the left and right sides, top and bottom surfaces, etc. are not illustrated.

[0032] An information processing device 100 such as a smartphone has, on its front surface, an LED (Light Emitting Diode) 124, a second image input unit 134, an audio output unit 141M, and a touch screen 190.

Furthermore, the touch panel 123 that constitutes the touch screen 190 may also have the function of the touch sensor 122. In this case, it is possible to execute the function of the touch sensor 122 (for example, a fingerprint authentication function) at any position on the touch screen 190. [Example of Software Configuration of Information Processing Device] Fig. 3 is a block diagram showing an example of the software configuration of the information processing device 100. Fig. 3 shows an example of the software configuration in the storage unit 110 and the RAM 103.

[0036] The storage unit 110 stores a basic operation program 1001 and an application 1002, and includes a storage area 1009 for various data.

[0037] The basic operation program 1001 is a basic program such as an OS. The application 1002 is an application that executes the functions of the present invention and various other applications. The various data storage area 1009 is an area for storing various operation setting values ​​and various information (moving images, still images, audio, etc.).

[0041] Note that each operation program may be stored in advance in the storage unit 110 at the time of product shipment. After product shipment, the operation programs may be acquired from each server device on the network via the wireless LAN communication unit 171 or the telephone network communication unit 172, etc. Furthermore, each operation program stored on a memory card, optical disk, etc. may be acquired via the extended interface unit 180, etc. [Example of Operation State Transition of Information Processing Device] FIG. 4 is a state transition diagram showing an example of state transition of the information processing device 100.

[0042] The information processing device 100 has a terminal lock function, and when the terminal lock function is enabled, user authentication processing is required to transition the terminal from a power-off state or a sleep state to a normal operating state in which it can be used.

[0043] The information processing device 100 can set (enable) / cancel (disable) the terminal lock function in response to an operational instruction from the user, and can switch between a normal operating state T100 in which the terminal lock function is disabled and a normal operating state T110 in which the terminal lock function is enabled. User authentication processing may be required to set / cancel the terminal lock function.

[0044] The applications 1002 in the storage unit 110 of the information processing device 100 include normal applications that are displayed on the display unit 131 in the normal operating state (terminal lock function enabled) T110 and the extended operating state (terminal lock function enabled) T120, and extended applications that are not displayed in the normal operating state (terminal lock function enabled) T110 but are displayed on the display unit 131 in the extended operating state (terminal lock function enabled) T120. Each application 1002 may be set as either a normal application or an extended application by the user at the time of installation, or may be automatically set as either a normal application or an extended application depending on the importance of the application.

[0045] The normal operation state (terminal lock function disabled) T100, the sleep state (terminal lock function disabled) T101, and the power-off state (terminal lock function disabled) T102 are normal operations in a state in which the terminal lock function is disabled. From a state in which the terminal lock function is disabled, it is not possible to transition to the extended operation state (terminal lock function enabled) T120.

[0046] In the normal operation state (terminal lock function disabled) T100, only normal applications are displayed and usable. When the user performs a lock setting operation to enable the terminal lock function in the normal operation state (terminal lock function disabled) T100, the state transitions to the normal operation state (terminal lock function enabled) T110. The lock setting operation is an operation to register PIN information, face image information, fingerprint information, etc., and enable the terminal lock function.

[0047] In the normal operation state (terminal lock function disabled) T100, if the user performs a sleep operation or if a predetermined time or more has passed without any operation, the state transitions to the sleep state (terminal lock function disabled) T101. In the normal operation state (terminal lock function disabled) T100, if the user performs a power-off operation, the state transitions to the power-off state (terminal lock function disabled) T102.

[0048] In the sleep state (terminal lock function disabled) T101, some functions such as screen display are suspended, but the device can return to the normal operation state (terminal lock function disabled) T100 in a short time. When the user performs a sleep release operation in the sleep state (terminal lock function disabled) T101, the device transitions to the normal operation state (terminal lock function disabled) T100. When the user performs a power-off operation in the sleep state (terminal lock function disabled) T101, the device transitions to the power-off state (terminal lock function disabled) T102.

[0049] In the power-off state (terminal lock function disabled) T102, many functions except for predetermined functions are suspended, and a process such as initialization is required to return to the normal operation state (terminal lock function disabled) T100. When the user turns on the power in the power-off state (terminal lock function disabled) T102, the state transitions to the normal operation state (terminal lock function disabled) T100.

[0050] The normal operation state (terminal lock function enabled) T110, the sleep state (terminal lock function enabled) T111, the power-off state (terminal lock function enabled) T112, and the first user authentication state T113 are normal operations in a state in which the terminal lock function is enabled. From a state in which the terminal lock function is enabled, it is possible to transition to an extended operation state.

[0051] In the normal operation state (terminal lock function enabled) T110, only normal applications are displayed and usable. When the user performs an unlock operation to disable the terminal lock function in the normal operation state (terminal lock function enabled) T110, the state transitions to the normal operation state (terminal lock function disabled) T100. The unlock operation disables the terminal lock function and erases registered PIN information, face image information, fingerprint information, etc. Although not shown, the terminal lock function is disabled after successful authentication by the user authentication process.

[0052] In the normal operation state (terminal lock function enabled) T110, if the user performs a sleep operation or if a predetermined time or more has passed without any operation, the state transitions to a sleep state (terminal lock function enabled) T111. If the user performs a power-off operation in the normal operation state (terminal lock function enabled) T110, the state transitions to a power-off state (terminal lock function enabled) T112. If the user performs a function-extension operation in the normal operation state (terminal lock function enabled) T110, the state transitions to a second user authentication state T123. The function-extension operation is an operation that triggers a transition from the normal operation state T110 to the extended operation state T120.

[0053] The sleep state (terminal lock function enabled) T111 is a state in which some functions such as screen display are suspended, and it is possible to return to the normal operation state (terminal lock function enabled) T110 in a short time. When a user performs a sleep wake-up operation in the sleep state (terminal lock function enabled) T111, the state transitions to a first user authentication state T113. When a user performs a power-off operation in the sleep state (terminal lock function enabled) T111, the state transitions to a power-off state (terminal lock function enabled) T112.

[0054] In the power-off state (terminal lock function enabled) T112, many functions except for predetermined functions are suspended, and a process such as initialization is required to return to the normal operation state (terminal lock function enabled) T110. When the user turns on the power in the power-off state (terminal lock function enabled) T112, the state transitions to the first user authentication state T113.

[0055] The first user authentication state T113 is a processing state for authenticating that the user is an authorized user of the terminal, and is, for example, a PIN input processing state, a facial image input processing state, a fingerprint information confirmation processing state, etc. If authentication is successful in the first user authentication state T113 using authentication information such as a PIN, facial image, or fingerprint input by the user, the state transitions to a normal operation state (terminal lock function enabled) T110. If authentication fails in the first user authentication state T113, the state transitions to a sleep state (terminal lock function enabled) T111.

[0056] The extended operation state (terminal lock function enabled) T120 and the second user authentication state T123 are extended operations in a state in which the terminal lock function is enabled.

[0057] The extended operation state (terminal lock function enabled) T120 is a state in which extended applications are displayed and usable in addition to normal applications. In the extended operation state (terminal lock function enabled) T120, if a sleep operation is performed by the user or if a predetermined time or more has passed without any operation, the state transitions to a sleep state (terminal lock function enabled) T111. If a power-off operation is performed by the user in the extended operation state (terminal lock function enabled) T120, the state transitions to a power-off state (terminal lock function enabled) T112. If a function reduction operation is performed by the user in the extended operation state (terminal lock function enabled) T120, the state transitions to a normal operation state (terminal lock function enabled) T110. The function reduction operation is an operation that triggers a transition from the extended operation state T120 to the normal operation state T110.

[0058] When the device transitions from the extended operation state (terminal lock function enabled) T120 to the sleep state (terminal lock function enabled) T111 / power-off state (terminal lock function enabled) T112 / normal operation state (terminal lock function enabled) T110, the device transitions from extended operation, in which extended applications can be displayed and used, to normal operation.

[0059] The second user authentication state T123 is a processing state for authenticating that the user is authorized to use the extended application, and is, for example, a PIN input processing state, a facial image input processing state, a fingerprint information confirmation processing state, etc.

[0060] In the second user authentication state T123, if authentication is successful based on authentication information such as a PIN, face image, or fingerprint entered by the user, the state transitions to the extended operation state (terminal lock function enabled) T120. If authentication fails in the second user authentication state T123, the state transitions to the normal operation state (terminal lock function enabled) T110.

[0061] According to the present embodiment, if authentication is successful in the first user authentication state T113, the state transitions to the normal operation state T110 in which normal applications are displayed, and if a function extension operation is performed in the normal operation state T110, the state transitions to the second user authentication state T123, and if authentication is successful in the second user authentication state T123, the state transitions to the extended operation state T120 in which normal applications and extended applications are displayed, so that it is possible to limit the applications displayed on the home screen after unlocking. [Example of a Screen of an Information Processing Device] Figure 5 is a diagram showing an example of a display screen of the information processing device 100. Figure 5 shows an example of a display screen when transitioning from the sleep state T111 / power-off state T112 via the first user authentication state T113 to the normal operation state T110.

[0062] The sleep state T111 is a state in which some functions, such as screen display, are suspended, and a date and time display screen 131T is displayed on the display unit 131 of the information processing device 100. When a sleep wake-up operation is performed in the sleep state T111, the device transitions to a first user authentication state T113. An example of the sleep wake-up operation is a short press of the power key 121P. When a power-off operation is performed in the sleep state T111, the device transitions to a power-off state T112. An example of the power-off operation is a long press of the power key 121P.

[0063] In the power-off state T112, most functions except for predetermined functions are suspended, and nothing is displayed on the display unit 131 of the information processing device 100. When a power-on operation is performed in the power-off state T112, the state transitions to a first user authentication state T113. The power-on operation is, for example, a long press of the power key 121P.

[0064] The first user authentication state T113 is a processing state for authenticating that the user is an authorized user of the information processing device 100. An authentication processing screen 131A1 is displayed on the display unit 131 of the information processing device 100. If authentication is successful in the first user authentication state T113 using authentication information such as a PIN, facial image, or fingerprint entered by the user, the state transitions to a normal operating state T110-1. If authentication fails in the first user authentication state T113, the state transitions to a sleep state T111. Here, face authentication processing is performed as an example of user authentication processing.

[0065] In the normal operating states T110-1 to T110-3, only the normal application 131C is displayed and the device is usable. Normal home screens 131H1 to 131H3 are displayed on the display unit 131 of the information processing device 100. Normal application icons 131C are displayed on the normal home screens 131H1 to 131H3. FIG. 5 shows an example in which there are three normal home screen pages. After the first authentication process, the normal home screen 131H1 (the first page of normal home screens) is displayed by default.

[0066] When a swipe operation is performed in the normal operating states T110-1 to T110-3, page switching is performed between the normal home screens 131H1 to 131H3.

[0067] When the user swipes left on the normal home screen 131H1, the display switches to the normal home screen 131H2. When the user swipes right on the normal home screen 131H1, the display of the normal home screen 131H1 may continue, or the display may switch to another gadget display screen.

[0068] When the user swipes left on the normal home screen 131H2, the display switches to the normal home screen 131H3. When the user swipes right on the normal home screen 131H2, the display switches to the normal home screen 131H1.

[0069] When the user swipes left on the normal home screen 131H3, the normal home screen 131H3 continues to be displayed, or a new normal home screen (page 4) may be created. When the user swipes right on the normal home screen 131H3, the display switches to the normal home screen 131H2.

[0070] Although not shown, if a sleep operation is performed in the normal operating states T110-1 to T110-3, the state transitions to a sleep state T111. An example of the sleep operation is a short press of the power key 121P. Also, if a power-off operation is performed in the normal operating states T110-1 to T110-3, the state transitions to a power-off state T112. An example of the power-off operation is a long press of the power key 121P. Also, if a function-expanding operation is performed in the normal operating states T110-1 to T110-3, the state transitions to a second user authentication state T123. The function-expanding operation and the transition from the normal operating state T110 to the second user authentication state T123 will be described later with reference to FIGS. 6 to 8.

[0071] A home screen number indicator 131P is displayed on the normal home screens 131H1 to 131H3. The number of marks on the home screen number indicator 131P corresponds to the number of normal home screen pages. The mark corresponding to the normal home screen currently being displayed on the home screen number indicator 131P is highlighted.

[0072] In a normal operating state T110-1 in which the normal home screen 131H1 is displayed, the mark on the left is highlighted, in a normal operating state T110-2 in which the normal home screen 131H2 is displayed, the mark in the center is highlighted, and in a normal operating state T110-3 in which the normal home screen 131H3 is displayed, the mark on the right is highlighted.

[0073] In the normal operating states T110-1 to T110-3, only the normal home screens 131H1 to 131H3 in which the normal application icon 131C is registered can be switched. The home screen number display 131P is also displayed only for pages corresponding to the normal home screens 131H1 to 131H3.

[0074] Fig. 6 is a diagram showing an example of a display screen of the information processing device 100. Fig. 6 shows an example of a display screen when transitioning from the normal operating state T110 to the extended operating state T120 via the second user authentication state T123.

[0075] The normal operating state T110 is the same as that shown in FIG. 5, and therefore a description thereof will be omitted.

[0076] When a function expansion operation is performed in the normal operating states T110-1 to T110-3, the state transitions to the second user authentication state T123. The function expansion operation can be performed from any of the normal home screens 131H1 to 131H3, but here we will explain an example of transitioning from the normal home screen 131H2.

[0077] The second user authentication state T123 is a processing state for authenticating that the user is authorized to use the extension application. An authentication processing screen 131A2 is displayed on the display unit 131 of the information processing apparatus 100.

[0078] In the second user authentication state T123, if authentication is successful based on authentication information such as a PIN, face image, or fingerprint entered by the user, the state transitions to an extended operating state T120-4. If authentication fails in the second user authentication state T123, the state transitions to the normal operating state T110-2 and returns to the page of the normal home screen 131H2 that was displayed before the transition to the second user authentication state T123. Here, a PIN input process is performed as an example of the user authentication process.

[0079] The extended operating state T120 is a state in which the extended application 131S is displayed and usable in addition to the normal application 131C. Normal home screens 131E1 to 131E3 and extended home screens 131E4 and 131E5 are displayed on the display unit 131 of the information processing device 100. The normal home screens 131E1 to 131E3 display a normal application icon 131C. The extended home screens 131E4 and 131E5 display an extended application icon 131S. FIG. 6 shows an example in which there are two pages of extended home screens and three pages of normal home screens. After the second user authentication process, the extended home screen 131E4 (the first page of extended home screens on which the extended application 131S is registered) is displayed by default.

[0080] Although FIG. 6 shows only the extended operating states T120-3 to T120-5, the extended operating states T120-1 and T120-2 are assumed to display the normal home screens 131E1 and 131E2, respectively.

[0081] When a swipe operation is performed in the extended operating states T120-1 to T120-5, page switching is performed between the normal home screens 131E1 to 131E3 and the extended home screens 131E4 and 131E5.

[0082] Swiping left on the normal home screen 131E1 switches the display to the normal home screen 131E2. Swiping right on the normal home screen 131E1 may continue to display the normal home screen 131E1, or may switch the display to another gadget display screen. Swiping left on the normal home screen 131E2 switches the display to the normal home screen 131E3. Swiping right on the normal home screen 131E2 switches the display to the normal home screen 131E1. Swiping left on the normal home screen 131E3 switches the display to the extended home screen 131E4. Swiping right on the normal home screen 131E3 switches the display to the normal home screen 131E2.

[0083] Swiping left on the extended home screen 131E4 switches the display to the extended home screen 131E5. Swiping right on the extended home screen 131E4 switches the display to the normal home screen 131E3. Swiping left on the extended home screen 131E5 allows the display of the extended home screen 131E5 to continue, or a new extended home screen (third page) to be created. Swiping right on the extended home screen 131E5 switches the display to the extended home screen 131E4.

[0084] Although not shown, if a sleep operation is performed in the extended operating states T120-1 to T120-5, the state transitions to the sleep state T111. The transition from the extended operating state T120 to the sleep state T111 will be described later with reference to FIG. 11. Also, if a power-off operation is performed in the extended operating states T120-1 to T120-5, the state transitions to the power-off state T112. Also, if a function reduction operation is performed in the extended operating states T120-1 to T120-5, the state transitions to the normal operating state T110. The function reduction operation and the transition from the extended operating state T120 to the normal operating state T110 will be described later with reference to FIGS. 9 and 10.

[0085] A home screen number indicator 131P is displayed on the normal home screens 131E1 to 131E3 and the extended home screens 131E4 and 131E5. The number of marks on the home screen number indicator 131P corresponds to the total number of pages of the extended home screens and normal home screens. The home screen number indicator 131P highlights the mark corresponding to the extended home screen or normal home screen that is currently displayed.

[0086] In the extended operating state T120-3 when the normal home screen 131E3 is displayed, the center mark is highlighted, in the extended operating state T120-4 when the extended home screen 131E4 is displayed, the second mark from the right is highlighted, and in the extended operating state T120-5 when the extended home screen 131E5 is displayed, the mark on the right is highlighted. Although not shown, when the normal home screen 131E1 is displayed, the mark on the left is highlighted, and when the normal home screen 131E2 is displayed, the second mark from the left is highlighted.

[0087] In the home screen number display 131P, the mark corresponding to the normal home screen and the mark corresponding to the extended home screen may have different shapes. For example, the mark corresponding to the extended home screen may be a star, and the mark corresponding to the normal home screen may be a circle. In addition, in the home screen number display 131P, the positional relationship between the extended home screen and the normal home screen may be reversed left to right.

[0088] The normal home screens 131E1 to 131E3 and the normal home screens 131H1 to 131H3 display the same normal applications, but the display state of the home screen number display 131P is different. The home screen number display 131P of the normal home screens 131E1 to 131E3 also displays a mark corresponding to the extended home screen, but the home screen number display 131P of the normal home screens 131H1 to 131H3 does not display a mark corresponding to the extended home screen. The display state of the home screen number display 131P makes it possible to determine whether the device is in the extended operating state or the normal operating state.

[0089] Fig. 7 is a diagram showing an example of a display screen of the information processing device 100. Fig. 7 shows an example of a display screen when transitioning from the normal operating state T110 to the extended operating state T120 via the second user authentication state T123, similar to Fig. 6, but whereas only the extended application icon 131S is displayed on the extended home screens 131E4 and 131E5 in Fig. 6, the extended application icon 131S and the normal application icon 131C are displayed on the extended home screen 131E2a in Fig. 7.

[0090] The normal operating state T110 and the second user authentication state T123 are the same as those in FIG. 6, and therefore description thereof will be omitted.

[0091] In the second user authentication state T123, if authentication is successful based on authentication information such as a PIN, face image, or fingerprint entered by the user, the state transitions to an extended operating state T120-2a. If authentication fails in the second user authentication state T123, the state transitions to the normal operating state T110-2, and returns to the page of the normal home screen 131H2 that was displayed before the transition to the second user authentication state T123. Here, a PIN input process is performed as an example of the user authentication process.

[0092] In the extended operating states T120-1a to T120-3a, the extended application 131S is displayed in addition to the normal application 131C and is usable. The display unit 131 of the information processing device 100 displays an extended home screen 131E2a and normal home screens 131E1a and 131E3a. The extended home screen 131E2a displays the extended application icon 131S and the normal application icon 131C, while the normal home screens 131E1a and 131E3a display only the normal application icon 131C. FIG. 7 shows an example in which there is one page of extended home screens and two pages of normal home screens. After the second user authentication process, the extended home screen 131E2a (the first page of extended home screens on which the extended application is registered) is displayed by default.

[0093] When a swipe operation is performed in the extended operating states T120-1a to T120-3a, page switching is performed between the extended home screen 131E2a and the normal home screens 131E1a and 131E3a.

[0094] Swiping left on the normal home screen 131E1a switches the display to the extended home screen 131E2a. Swiping right on the normal home screen 131E1a may continue displaying the normal home screen 131E1a or may switch the display to another gadget display screen.

[0095] When the user swipes left on the extended home screen 131E2a, the display switches to the normal home screen 131E3a. When the user swipes right on the extended home screen 131E2a, the display switches to the normal home screen 131E1a.

[0096] When the user swipes left on the normal home screen 131E3a, the normal home screen 131E3a continues to be displayed, or a new extended home screen (page 2) or a new normal home screen (page 3) may be created. When the user swipes right on the normal home screen 131E3a, the display switches to the extended home screen 131E2a.

[0097] Although not shown, if a sleep operation is performed in the extended operating states T120-1a to T120-3a, the state transitions to the sleep state T111. The transition from the extended operating state T120 to the sleep state T111 will be described later with reference to FIG. 11. Also, if a power-off operation is performed in the extended operating states T120-1a to T120-3a, the state transitions to the power-off state T112. Also, if a function reduction operation is performed in the extended operating states T120-1a to T120-3a, the state transitions to the normal operating state T110. The function reduction operation and the transition from the extended operating state T120 to the normal operating state T110 will be described later with reference to FIGS. 9 and 10.

[0098] After successful authentication by the second user authentication process, the extended application icon 131S may be additionally displayed on the extended home screens E1a to E3a corresponding to all normal home screens 131H1 to 131H3, or may be additionally displayed only on the extended home screen 131E2a corresponding to the normal home screen 131H2 that was displayed before the function extension operation was performed.

[0099] A home screen number indicator 131P is displayed on the extended home screen 131E2a and the normal home screens 131E1a and 131E3a. The number of marks on the home screen number indicator 131P corresponds to the total number of pages of the extended home screens and normal home screens. The home screen number indicator 131P highlights the mark corresponding to the extended home screen or normal home screen currently being displayed.

[0100] In the extended operating state T120-1a when the normal home screen 131E1a is displayed, the mark on the left is highlighted, in the extended operating state T120-2a when the extended home screen 131E2a is displayed, the mark in the center is highlighted, and in the extended operating state T120-3a when the normal home screen 131E3a is displayed, the mark on the right is highlighted.

[0101] In the home screen number display 131P, the mark corresponding to the normal home screen and the mark corresponding to the extended home screen to which the extended application icon 131S has been added may have different shapes. For example, the mark corresponding to the extended home screen to which the extended application icon 131S has been added may be a star, and the mark corresponding to the normal home screen may be a circle.

[0102] The normal home screens 131E1a, 131E3a and the normal home screens 131H1, 131H3 display the same normal applications, but the display state of the home screen number display 131P is different. The home screen number display 131P of the normal home screens 131E1a, 131E3a also displays a mark corresponding to the extended home screen, but the home screen number display 131P of the normal home screens 131H1, 131H3 does not display a mark corresponding to the extended home screen. The display state of the home screen number display 131P makes it possible to determine whether the device is in the extended operating state or the normal operating state.

[0103] 8 is a diagram showing an example of a function extension operation of the information processing device 100. The function extension operation is an operation that triggers a transition from the normal operating state T110 to the extended operating state T120. When an operation such as the following example is detected in the normal operating state T110, a transition to the second user authentication state T123 occurs.

[0104] Examples of function expansion operations include (A) an operation in which user U1 taps (knocks) a blank portion of display unit 131 a predetermined number of times, (B) an operation in which user U1 swipes (in) from a predetermined direction outside display unit 131 to the inside of display unit 131, and (C) an operation in which user U1 taps (launches) extended function portal icon 131C1 registered on normal home screens 131E1 to 131E3. The extended function portal icon 131C1 may be a dummy icon.

[0105] Although not shown, other examples of the function expansion operation include an operation of tapping the housing of the information processing device 100 (other than the display unit 131) a predetermined number of times, an operation of shaking the housing of the information processing device 100 a predetermined number of times, an operation of pinching out the portion of the display unit 131 on which the number of home screens is displayed 131P, an operation of inputting a predetermined voice word into the voice input unit 143 after fingerprint authentication has been performed using the touch sensor 122, an operation of inputting a predetermined voice word into the voice input unit 143 after face authentication has been performed using the second image input unit 134, etc. When the operation of tapping the housing of the information processing device 100 (other than the display unit 131) a predetermined number of times or the operation of shaking the housing of the information processing device 100 a predetermined number of times is performed, the information processing device 100 transitions to the second user authentication state T123 by detecting vibrations of the information processing device 100.

[0106] The authentication process performed in the first user authentication process state T113 and the authentication process performed in the second user authentication process state T123 may be different authentication processes or the same authentication process. The same authentication process may be performed with different authentication strengths. The first user authentication and the second user authentication may be enabled or disabled differently.

[0107] Examples of combinations of first user authentication and second user authentication include: first user authentication being a facial authentication process and second user authentication being a PIN input process; first user authentication being a fingerprint authentication process and second user authentication being a credit card or personal identification number card touch process (device-to-device authentication process using NFC communication); first user authentication being a 4-digit PIN input process and second user authentication being a 6-digit PIN input process; first user authentication being a facial authentication process and second user authentication being a simultaneous process of facial authentication and fingerprint authentication; etc.

[0108] Next, an example of processing when the second user authentication fails will be described.

[0109] In a first example of processing when second user authentication fails, if a function extension operation is performed in the normal operating state T110 and authentication fails in the second user authentication state T123, the state transitions to the normal operating state T110 and returns to the normal home screen page that was displayed before transitioning to the second user authentication state T123. As a result, for example, if a criminal who has stolen the information processing device 100 attempts second user authentication but fails, the extension application is not displayed.

[0110] In a second example of processing when second user authentication fails, if a function expansion operation is performed in the normal operating state T110 and authentication fails in the second user authentication state T123, the operating state of the information processing device 100 remains in the normal operating state T110 while a dummy home screen is displayed. The dummy home screen is, for example, a page on which the same normal application icons are displayed in a different layout. This prevents, for example, a criminal who has stolen the information processing device 100 from learning of the authentication failure when attempting second user authentication and failing.

[0111] In a third example of processing when second user authentication fails, if a function extension operation is performed in the normal operating state T110 and authentication fails in the second user authentication state T123, a message indicating the authentication failure is sent to a pre-registered external terminal device without displaying a message indicating the authentication failure on the information processing device 100. As a result, for example, if a criminal who has stolen the information processing device 100 attempts second user authentication but fails, the criminal will not be able to know of the authentication failure, and the user will be able to know of the authentication failure via the external terminal device.

[0112] Fig. 9 is a diagram showing an example of a display screen of the information processing apparatus 100. Fig. 9 shows an example of a display screen when transitioning from the extended operating state T120 to the normal operating state T110.

[0113] The extended operating state T120 is the same as that shown in FIG. 6, and therefore a description thereof will be omitted.

[0114] The extended operating state T120 transitions to the normal operating state T110 after a predetermined time has elapsed. As a result, for example, if the information processing device 100 is stolen after the second user authentication is successful, the extended application will not be displayed.

[0115] In the extended operating states T120-1 to T120-3 while the normal home screens 131E1 to 131E3 are displayed, if a predetermined time has elapsed, the state transitions to the normal operating state T110, even if an operation is performed on a normal application. For example, if a predetermined time has elapsed while the normal home screen 131E1 is displayed, the state transitions to the normal home screen 131H1. Furthermore, if a predetermined time has elapsed while the normal home screen 131E2 is displayed (extended operating state T110-2), the state transitions to the normal home screen 131H2. Furthermore, if a predetermined time has elapsed while the normal home screen 131E3 is displayed, the state transitions to the normal home screen 131H3. Even after transitioning to the normal operating state T110, the normal applications displayed on the display unit 131 remain the same; only the operating state and the display state of the home screen number display 131P change. If a normal application is in use, the use state may continue.

[0116] In the extended operating states T120-4 and T120-5 in which the extended home screens 131E4 and 131E5 are displayed, if a predetermined time or more has passed without any operation being performed on the extended application, the state transitions to the normal operating state T110. If the extended application is in use, the operating state does not change until the use of the extended application ends.

[0117] For example, if a predetermined time has passed while the extended home screen 131E4 is displayed (extended operating state T120-4), the screen transitions to the normal home screen 131H1. Similarly, if a predetermined time has passed while the extended home screen 131E5 is displayed, the screen transitions to the normal home screen 131H1. That is, if a predetermined time has passed while the extended home screen 131E4 or 131E5 is displayed, the screen transitions to the default display of the normal home screen (normal home screen 131H1).

[0118] When the operating state is the extended operating state T120, transition from the normal home screens 131E1 to 131E3 to the extended home screens 131E4 and 131E5 is possible with just a swipe operation. On the other hand, when the operating state is transitioned from the extended operating state T120 to the normal operating state T110, transition from the normal home screens 131H1 to 131H3 to the extended home screens 131E4 and 131E5 requires second user authentication processing.

[0119] The predetermined time may be different when the normal home screens 131E1 to 131E3 are displayed and when the extended home screens 131E4 and 131E5 are displayed. The predetermined time may also be zero. For example, when a right swipe operation is performed on the extended home screen 131E4, the display may switch to the normal home screen 131H3, and the operating state may immediately transition from the extended operating state T120 to the normal operating state T110.

[0120] The normal operating state T110 is the same as that shown in FIG. 5, and therefore a description thereof will be omitted.

[0121] 10 is a diagram showing an example of a function reduction operation of the information processing device 100. The function reduction operation is an operation that triggers a transition from the extended operating state T120 to the normal operating state T110. When an operation such as the following example is detected in the extended operating state T120, the state transitions to the normal operating state T110. After using an extended application, the user can perform a function reduction operation to return from the extended operating state T120 to the normal operating state T110, thereby preventing the extended application from being displayed.

[0122] Examples of function reduction operations include (A) an operation in which user U1 taps (knocks) a part of display unit 131 where nothing is displayed a predetermined number of times, (B) an operation in which user U1 swipes (out) from inside display unit 131 to a predetermined direction outside display unit 131, and (C) an operation in which user U1 double-tap the home key 131K1 displayed on extended home screens 131E4 and 131E5 (see reference).

[0123] Although not shown, other examples of function reduction operations include an operation of tapping the housing of the information processing device 100 (other than the display unit 131) a predetermined number of times, an operation of shaking the housing of the information processing device 100 a predetermined number of times, an operation of pinching in on the portion of the home screen number display 131P on the display unit 131, the passage of a predetermined time or more without any operation while the extended home screens 131E4 and 131E5 or the normal home screens 131E1 to 131E3 are displayed, etc. When the operation of tapping the housing of the information processing device 100 (other than the display unit 131) a predetermined number of times or the operation of shaking the housing of the information processing device 100 a predetermined number of times is performed, vibration of the information processing device 100 is detected, and the information processing device 100 transitions to the normal operating state T110.

[0124] Fig. 11 is a diagram showing an example of a display screen of the information processing device 100. Fig. 11 shows an example of a display screen when transitioning from the extended operating state T120 to the sleep state T111, and from the sleep state T111 to the normal operating state T110 / extended operating state T120 via the first user authentication state T113 / second user authentication state T123.

[0125] The extended operating state T120 is the same as that shown in FIG. 6, and therefore a description thereof will be omitted.

[0126] When a sleep operation is performed in the extended operating state T120, the state transitions to a sleep state T111. In the sleep state T111, some functions such as screen display are suspended, and a date and time display screen 131T is displayed on the display unit 131 of the information processing device 100. Although not shown, when a power-off operation is performed in the sleep state T111, the state transitions to a power-off state T112.

[0127] When a wake-up operation is performed in the sleep state T111, the state transitions to a first user authentication state T113 or a second user authentication state T123. Here, if a wake-up operation is performed after a predetermined time has elapsed since the transition to the sleep state, the state transitions to the first user authentication state T113, and if a wake-up operation is performed before the predetermined time has elapsed since the transition to the sleep state, the state transitions to the second user authentication state T123.

[0128] The predetermined time may be set to zero. That is, the state may always transition to the first user authentication state T113 upon a sleep wake-up operation.

[0129] The first user authentication state T113 is a processing state for authenticating that the user is an authorized user of the terminal. An authentication processing screen 131A1 is displayed on the display unit 131 of the information processing device 100. If authentication is successful in the first user authentication state T113 using authentication information such as a PIN, facial image, or fingerprint entered by the user, the device transitions to the normal operating state T110. If authentication fails in the first user authentication state T113, the device transitions to the sleep state T111.

[0130] The second user authentication state T123 is a processing state for authenticating that the user is authorized to use the extended application. An authentication processing screen 131A2 is displayed on the display unit 131 of the information processing device 100. If authentication is successful in the second user authentication state T123 based on authentication information such as a PIN, face image, or fingerprint entered by the user, the state transitions to the extended operation state T120. If authentication fails in the second user authentication state T123, the state transitions to the sleep state T111.

[0131] The normal operating state T110 is the same as that shown in FIG. 5, and therefore a description thereof will be omitted.

[0132] Fig. 12 is a diagram showing an example of a display screen of the information processing device 100. Fig. 12 shows an example of a display screen when transitioning from the extended operating state T120 to the power-off state T112, and from the power-off state T112 to the normal operating state T110 via the first user authentication state T113.

[0133] The extended operating state T120 is the same as that shown in FIG. 6, and therefore a description thereof will be omitted.

[0134] When a power-off operation is performed in the extended operation state T120, the state transitions to the power-off state T112. In the power-off state T112, many functions except for predetermined functions are suspended. Nothing is displayed on the display unit 131 of the information processing device 100. When a power-on operation is performed in the power-off state T112, the state transitions to the first user authentication state T113. Unlike in FIG. 11 , when a power-on operation is performed, the state transitions to the first user authentication state T113 regardless of the time that has elapsed since the transition to the power-off state T112.

[0135] The first user authentication state T113 is a processing state for authenticating that the user is an authorized user of the terminal. An authentication processing screen 131A1 is displayed on the display unit 131 of the information processing device 100. If authentication is successful in the first user authentication state T113 using authentication information such as a PIN, facial image, or fingerprint entered by the user, the device transitions to the normal operating state T110. If authentication fails in the first user authentication state T113, the device transitions to the sleep state T111.

[0136] The normal operating state T110 is the same as that shown in FIG. 5, and therefore a description thereof will be omitted.

[0137] FIG. 13 is a diagram showing an example of a setting screen calling operation of the information processing device 100. In FIG.

[0138] (A) shows a case where a setting screen is called from the normal operating state T110. When a menu call operation is performed in the normal operating state T110, the state transitions to the normal operating state (menu call state) T110M, and a menu 131M is displayed at the top of the screen. As an example of a menu call operation, here, the user U1 swipes from outside the upper part of the display unit 131 to inside the screen.

[0139] The normal operating state (menu call state) T110M is a state in which the menu 131M is superimposed on the normal home screens 131H1 to 131H3. When a settings screen call operation is performed in the normal operating state (menu call state) T110M, the state transitions to the normal operating state (settings screen display state) T110S. As an example of the settings screen call operation, here, the user U1 taps the settings icon 131M1.

[0140] The normal operating state (setting screen display state) T110S is a state in which a setting screen 131S1 related to the normal operating state of the information processing device 100 is displayed. The setting screen 131S1 displays setting menus such as terminal information, application settings, display settings, audio settings, security settings, and terminal lock settings.

[0141] In the application settings on the setting screen 131S1, it is possible to change or update the settings only for the normal applications (Na to Np) that can be displayed and used in the normal operating state. This makes it possible to limit the applications that are displayed on the setting screen after unlocking, and to prevent others from finding out about the existence of extended applications from the setting screen.

[0142] (B) shows a case where a setting screen is called from the extended operation state T120. When a menu call operation is performed in the extended operation state T120, the state transitions to an extended operation state (menu call state) T120M, and a menu 131M is displayed at the top of the screen. As an example of a menu call operation, here, the user U1 swipes from outside the upper part of the display unit 131 to inside the screen.

[0143] The extended operation state (menu call state) T120M is a state in which the menu 131M is superimposed on the extended home screens 131E4 and 131E5 or the normal home screens 131E1 to 131E3. When a settings screen call operation is performed in the extended operation state (menu call state) T120M, the state transitions to the extended operation state (settings screen display state) T120S. Here, tapping the settings icon 131M1 is an example of the settings screen call operation.

[0144] The extended operation state (setting screen display state) T120S is a state in which a setting screen 131S2 related to the extended operation state of the information processing device 100 is displayed. The setting screen 131S2 displays setting menus such as terminal information, application settings, display settings, audio settings, security settings, and terminal lock settings.

[0145] In addition, the application settings on the settings screen 131S2 allow settings to be changed or updated for normal applications (Na to Np) that can be displayed and used in normal operating state, and extended applications (Sa to Se) that can be displayed and used in extended operating state.

[0146] Although an example of an embodiment has been described above, it goes without saying that the configuration for realizing the technology of the present embodiment is not limited to the above, and various modifications are possible. The above-described configuration may be realized in part or in whole by hardware, for example, by designing it as an integrated circuit. It may also be realized in software by a microprocessor unit or the like interpreting and executing a program that realizes each function. Hardware and software may also be used together.
