Description

[Technical field]

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

[0002] In recent years, information processing devices with a remote control function have been developed to prevent information leakage due to loss, theft, etc. With such information processing devices, even if the device is lost or stolen, data stored in the information processing device can be erased by remote control, making it possible to prevent information leakage. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2006-303817 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, for example, when an information processing device receives a data deletion instruction by remote control, the data stored in the information processing device is deleted even if the information processing device is returned to the user without any operation by a third party. In order to reuse the information processing device that has been returned to the user, the user needs to recover and set up the OS (Operating System), which takes time before the information processing device can be used again, which is a burden on the user.

[0005] For this reason, in the event that an information processing device is lost or stolen and receives an erasure instruction, users would like the information processing device to be returned to them so that they can be reused immediately without data erasure being performed unless a third party operates the device, and there is room for further improvement.

[0006] Therefore, one example of a problem to be solved by the present invention is to provide an information processing device and an information processing method that can erase data stored in an auxiliary storage device depending on whether or not an operation by a third party has been performed. [Means for solving the problem]

[0007] An information processing device according to a first aspect of the present invention includes a receiving unit that receives remote instruction information indicating information regarding the erasure of data to be stored in an auxiliary storage device, and an execution unit that, upon receiving the remote instruction information, transitions to a standby state for executing the erasure of the data, and, in the standby state, executes the erasure of the data if predetermined conditions are satisfied.

[0008] The specified condition may include at least one of the following conditions: a power button provided on the information processing device is pressed; the information processing device is out of communication range for a specified period of time; a back cover opening / closing mechanism provided on the information processing device is removed; and a battery supplying power to the information processing device does not meet a specified capacity.

[0009] Furthermore, the execution unit may not execute the erasure of the data if the receiving unit receives remote instruction information including an instruction to cancel the erasure of the data before the predetermined condition is satisfied.

[0010] Furthermore, an information processing method according to a second aspect of the present invention is an information processing method executed in an information processing device, and includes a receiving process of receiving remote instruction information indicating information regarding the erasure of data to be stored in an auxiliary storage device, and an execution process of transitioning to a standby state for executing the erasure of the data upon receiving the remote instruction information, and executing the erasure of the data if predetermined conditions are satisfied in the standby state. Effect of the Invention

[0011] According to the present invention, data stored in an auxiliary storage device can be erased depending on whether or not an operation has been performed by a third party. [Brief description of the drawings]

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the embodiment shown below is merely an example, and there is no intention to exclude the application of various modified examples and techniques not specified in the embodiment. In other words, the present embodiment can be implemented with various modifications within the scope of the gist of the embodiment. In addition, each figure does not intend to include only the components shown in the figure, but can include other functions, etc.

[0014] 1 is a configuration diagram of an information processing system including an information processing device according to this embodiment and an external server. The information processing system 100 is composed of an information processing device 1 and an external server 2 connected via an external network. The information processing device 1 is, for example, a notebook personal computer. Note that the information processing device 1 may be, for example, a tablet terminal or the like in the form of a terminal.

[0015] The external server 2 is a server that provides services to devices connected thereto. The external server 2 is composed of, for example, a CPU (Central Processing Unit), a communication I / F (Interface), and the like. The external server 2 of this embodiment is, for example, a server for centrally monitoring and managing the information processing device 1 used by a user. The external server 2 manages, for example, the information processing device 1 that it monitors and manages by remote control, centralized management of functions provided in the information processing device 1, or distribution of a program to be installed in the information processing device 1.

[0016] 2 is a block diagram showing an example of a hardware configuration of an information processing device 1 according to an embodiment. The information processing device 1 illustrated here has a configuration similar to that of a general-purpose computer. The information processing device 1 includes a CPU 11, a RAM (Random Access Memory) 12, a ROM (Read Only Memory) 13, an auxiliary storage device 14, a user I / F 15, a display device 16, a communication I / F 17, a power button 18, a battery 19, and a back cover opening / closing mechanism 20, which are connected to one another via a bus 21.

[0017] The CPU 11 performs predetermined arithmetic processing using the RAM 12 as a working area according to programs stored in the ROM 13 and the auxiliary storage device 14. The ROM 13 is a volatile memory. The auxiliary storage device 14 is a non-volatile memory, and stores various data such as an OS (Operating System) required for processing by the CPU 11. The auxiliary storage device 14 is formed, for example, of an HDD (Hard Disc Drive) or an SSD (Solid State Drive). The auxiliary storage device 14 is an example of a storage unit.

[0018] The user I / F 15 is, for example, various input devices such as a keyboard, a touch panel, a mouse, etc. The user I / F 15 is an example of an operation unit. The display device 16 is, for example, a display device, etc., and displays various screens such as a display screen to a user who uses the information processing device 1. The display device 16 is an example of a display unit.

[0019] The communication I / F 17 can communicate with the external server 2, for example, via a network (for example, a wired LAN (Local Area Network), a wireless LAN, and a WAN (Wide Area Network), a public network such as an LTE or 5G line). The communication I / F 17 also monitors, for example, the communication status of the network, and transmits communication status information indicating whether communication with the external server 2 is possible or impossible to the external server 2. Furthermore, the communication I / F 17 acquires, for example, a GPS (Global Positioning System) signal, acquires current location information (for example, latitude and longitude information) of the location where the information processing device 1 is currently located, and transmits it to the external server 2. Note that the location information may be acquired from the communication status of the WAN.

[0020] The power button 18 is a button for turning on / off the power of the information processing device 1. The power button 18 is an example of an operation unit. The battery 19 is a driving source that supplies power to the information processing device 1. For example, when the power button 18 is turned on by a user's operation, the battery 19 supplies power to the information processing device 1. Also, when the power button 18 is turned off by a user's operation, the battery 19 does not supply power to the information processing device 1. The back cover opening / closing mechanism 20 is a member that covers the housing of the information processing device 1. Also, the back cover opening / closing mechanism 20 includes wiring for detecting that the back cover has been removed (opened). When the wiring is cut, the back cover opening / closing mechanism 20 detects that the back cover has been removed.

[0021] 3 is a block diagram showing an example of a functional configuration of the information processing device 1 according to the embodiment. The information processing device 1 according to the embodiment includes a receiving unit 31, a first judgment unit 32, a second judgment unit 33, a first determination unit 34, a first execution unit 35, a first transmission unit 36, an acquisition unit 37, a third judgment unit 38, a second execution unit 39, a second determination unit 40, and a second transmission unit 41. The receiving unit 31, the first judgment unit 32, the second judgment unit 33, the first determination unit 34, the first execution unit 35, the first transmission unit 36, the acquisition unit 37, the third judgment unit 38, the second execution unit 39, the second determination unit 40, and the second transmission unit 41 may be configured by, for example, the hardware elements of the information processing device 1 as illustrated in FIG. 2 in cooperation with software elements (such as programs stored in the ROM 13 or the auxiliary storage device 14). Note that the functional configuration of the information processing device 1 is not limited to the above.

[0022] The receiving unit 31 receives a remote instruction indicating an instruction to delete data stored in the auxiliary storage device 14. Specifically, the receiving unit 31 receives a remote instruction indicating an instruction to delete data stored in the auxiliary storage device 14 from the external server 2.

[0023] The remote instruction includes, for example, the content of erasing the data stored in the auxiliary storage device 14. The remote instruction also includes, for example, the content of not erasing the data stored in the auxiliary storage device 14.

[0024] Here, when the external server 2 transmits a remote instruction including a content not to erase data stored in the auxiliary storage device 14, for example, if the information processing device 1 is lost or stolen, and the information processing device 1 that received the erase instruction is not operated by a third party, there is no need to erase the data. In such an event, the external server 2 transmits a remote instruction including a content not to erase the data to the information processing device 1.

[0025] The remote instruction also includes the timing to erase the data. The timing to delete the data is, for example, an immediate erase instruction indicating the timing to erase the data immediately after receiving the remote instruction, a time-limited erase instruction indicating the timing to erase the data after a predetermined period has elapsed after receiving the remote instruction, a time-limited erase cancel instruction indicating the cancellation of the time-limited erase instruction after receiving the remote instruction, etc. The time-limited erase instruction may also include the timing to erase the data at a specified date and time.

[0026] The first determination unit 32 determines whether the content of the remote instruction is a time-limited erasure instruction. Specifically, the first determination unit 32 determines whether the content of the remote instruction received by the receiving unit 31 is a time-limited erasure instruction.

[0027] The second determination unit 33 determines whether the content of the remote instruction is a time-limited erasure cancel instruction. Specifically, when the first determination unit 32 determines that the content of the remote instruction is not a time-limited erasure cancel instruction, the second determination unit 33 determines whether the content of the remote instruction is a time-limited erasure cancel instruction. Here, when the second determination unit 33 determines that the content of the remote instruction is not a time-limited erasure cancel instruction, the content of the remote instruction is, for example, an immediate erasure instruction that indicates the timing to execute data erasure immediately after receiving the remote instruction.

[0028] The first determination unit 34 turns on the time-limited erasure standby flag based on the remote instruction. Specifically, when the first judgment unit 32 judges that the content of the remote instruction is a time-limited erasure instruction, the first determination unit 34 turns on the time-limited erasure standby flag. Also, the first determination unit 34 turns off the time-limited erasure standby flag based on the remote instruction. Specifically, when the first judgment unit 32 judges that the content of the remote instruction is a time-limited erasure cancel instruction, the first determination unit 34 turns off the time-limited erasure standby flag.

[0029] Here, the time-limited erasure standby flag will be explained. The time-limited erasure standby flag is a flag corresponding to the timing for erasing data included in a remote instruction. When the time-limited erasure standby flag is set, in other words, the state is waiting for the process of erasing data stored in the auxiliary storage device 14. Then, the first determination unit 34 stores the determined time-limited erasure standby flag in the storage unit. The state in which the time-limited erasure standby flag is set is an example of a standby state.

[0030] The first execution unit 35 executes erasure of data stored in the auxiliary storage device 14 of the information processing device 1. The first execution unit 35 is an example of an execution unit. Specifically, when the second determination unit 33 determines that the content related to the remote instruction is not a time-limited erasure cancellation instruction, the first execution unit 35 executes erasure of data stored in the auxiliary storage device 14 of the information processing device 1.

[0031] The first transmission unit 36 ​​transmits the processing result. Specifically, in response to the remote instruction received by the reception unit 31, the first transmission unit 36 ​​transmits to the external server 2 the processing result corresponding to the reception result indicating that the remote instruction has been received. The first transmission unit 36 ​​also transmits the processing result corresponding to the on / off of the timed erasure standby flag determined by the first determination unit 34. Furthermore, the first transmission unit 36 ​​transmits the processing result corresponding to the erasure of data to be stored in the auxiliary storage device 14 of the information processing device 1, which is executed by the first execution unit 35.

[0032] Here, the processing result transmitted by the first transmission unit 36 ​​includes current location information of the information processing device 1 when the remote instruction was received, which allows the external server 2 to know the location from which the information processing device 1 is transmitting the processing result.

[0033] Incidentally, when the information processing device 1 receives a remote instruction including an instruction to erase data stored in the auxiliary storage device 14 by remote operation, the data stored in the auxiliary storage device 14 is erased even when the information processing device 1 is returned to the user without any operation by a third party. In order to reuse the information processing device 1 that has been returned to the user, the user needs to recover and set up the OS (Operating System), which takes time before the information processing device 1 can be used again, which is a burden on the user.

[0034] Therefore, when the information processing device 1 in this embodiment receives a remote instruction, it transitions to a standby state for erasing data, and if a predetermined condition is satisfied in the standby state, it erases the data. Here, the contents related to the case where the predetermined condition is satisfied in the standby state will be described below.

[0035] The acquisition unit 37 acquires a predetermined condition in a standby state. The predetermined condition includes a condition that is satisfied when an operation by a third party has been performed. The predetermined condition includes at least one of the following conditions: the power button 18 provided on the information processing device 1 has been pressed, the information processing device 1 has been out of communication range for a predetermined period of time, the back cover opening / closing mechanism 20 provided on the information processing device 1 has been removed, and the battery 19 that supplies power to the information processing device 1 does not have a predetermined capacity.

[0036] For example, when the information processing device 1 that the user lost is returned to the user, the user notifies the administrator who manages the information processing device 1 that the information processing device 1 has been returned. The information processing device 1 can receive a remote instruction including a content not to erase data from the external server 2. Then, the information processing device 1 turns off the timed erasure standby flag and executes not to erase data.

[0037] This allows the user to use the information processing device 1 from which data has not been erased. On the other hand, pressing the power button 18 of the information processing device 1 in the standby state can be determined to be an operation by a third party because the above-mentioned content is not executed. Therefore, the acquisition unit 37 acquires that the power button 18 provided on the information processing device 1 has been pressed in the standby state.

[0038] Also, for example, when the information processing device 1 is in a standby state and the out-of-communication-range state continues for a predetermined time, the information processing device 1 in the out-of-communication-range state may be operated by a third party. Therefore, the acquisition unit 37 acquires that the information processing device 1 is in a standby state and the out-of-communication-range state continues for a predetermined time.

[0039] Furthermore, for example, the removal of the back cover opening / closing mechanism 20 provided in the information processing device 1 in the standby state may be a case where the auxiliary storage device 14 has been taken out by a third party. Therefore, the acquisition unit 37 acquires the fact that the back cover opening / closing mechanism 20 provided in the information processing device 1 has been removed in the standby state.

[0040] For example, in a standby state, if the battery 19 that supplies power to the information processing device 1 does not reach a predetermined capacity, it may result in a state in which communication with the external server 2 is disabled. If communication with the external server 2 is disabled, the information processing device 1 cannot be managed by the external server 2, and there is a possibility that it may be operated by a third party.

[0041] Therefore, the acquiring unit 37 acquires that the battery 19 supplying power to the information processing device 1 does not reach a predetermined capacity in the standby state. Here, the predetermined capacity is, for example, a capacity at which the connection between the information processing device 1 and the external server 2 is not disabled. The predetermined capacity may also be a capacity at which the power required to erase data is insufficient.

[0042] The third determination unit 38 determines whether or not the time-limited deletion standby flag is ON in the standby state. Specifically, when the acquisition unit 37 acquires a predetermined condition, the third determination unit 38 determines whether or not the time-limited deletion standby flag determined by the first determination unit 34 is ON.

[0043] The second execution unit 39 executes data erasure when a predetermined condition is satisfied in the standby state. Specifically, the second execution unit 39 executes erasure of data stored in the auxiliary storage device 14 of the information processing device 1 when the third determination unit 38 determines that the time-limited erasure standby flag determined by the first determination unit 34 is ON in the standby state.

[0044] Furthermore, in the standby state, if the receiving unit 31 receives remote instruction information including an instruction to cancel the data erasure before a predetermined condition is satisfied, the second executing unit 39 does not execute the data erasure. The second executing unit 39 is an example of an executing unit.

[0045] When the data erasure is executed, the second determination unit 40 turns off the time-limited erasure standby flag. Specifically, when the second execution unit 39 executes the data erasure, the second determination unit 40 turns off the time-limited erasure standby flag.

[0046] The second transmission unit 41 transmits the processing result. Specifically, the second transmission unit 41 transmits the processing result corresponding to the erasure of data stored in the auxiliary storage device 14 of the information processing device 1 executed by the second execution unit 39, and the information on the predetermined condition acquired by the acquisition unit 37. Here, the processing result transmitted by the second transmission unit 41 includes the current location information of the information processing device 1 when the remote instruction was received. This allows the external server 2 to know from where the information processing device 1 is transmitting the processing result.

[0047] Next, the process executed by the information processing device 1 will be described with reference to Fig. 4 and Fig. 5. Fig. 4 and Fig. 5 are flowcharts showing an example of the process executed by the information processing device 1 according to the embodiment. Fig. 4 describes the process that starts when the information processing device 1 is not in the possession of the user who uses the information processing device 1 due to loss, theft, etc.

[0048] 4, the receiving unit 31 receives a remote instruction indicating an instruction to erase data stored in the auxiliary storage device 14 from the external server 2 (step S51). Next, the first determination unit 32 determines whether the content of the remote instruction received by the receiving unit 31 is a time-limited erasure instruction (step S52).

[0049] Here, if the first determination unit 32 determines that the content of the remote instruction received by the receiving unit 31 is a time-limited erasure instruction (step S52: Yes), the process proceeds to step S54. On the other hand, if the first determination unit 32 determines that the content of the remote instruction received by the receiving unit 31 is not a time-limited erasure instruction (step S52: No), the process proceeds to step S53.

[0050] In step S53, the second judgment unit 33 judges whether the content of the remote instruction is a time-limited erasure cancel instruction (step S53). If the second judgment unit 33 judges that the content of the remote instruction is not a time-limited erasure cancel instruction (step S53: No), the process proceeds to step S56. On the other hand, if the second judgment unit 33 judges that the content of the remote instruction is a time-limited erasure cancel instruction (step S53: Yes), the process proceeds to step S55.

[0051] In step S54, if the first judgment unit 32 judges that the remote instruction is a time-limited erasure instruction, the first decision unit 34 turns on the time-limited erasure standby flag (step S54). In step S55, if the first judgment unit 32 judges that the remote instruction is a time-limited erasure cancel instruction, the first decision unit 34 turns off the time-limited erasure standby flag (step S55). In step S56, the first execution unit 35 executes erasure of the data stored in the auxiliary storage device 14 of the information processing device 1 (step S56).

[0052] In step S57, the first transmission unit 36 ​​transmits the processing result (step S57). For example, in response to the processing of step S51, the first transmission unit 36 ​​transmits to the external server 2 the processing result corresponding to the reception result indicating that the remote instruction has been received by the reception unit 31 in response to the remote instruction received by the reception unit 31.

[0053] Moreover, in response to the processing of step S54 or step S55, the first transmission unit 36 ​​transmits a processing result corresponding to the on / off of the time-limited erasure standby flag determined by the first determination unit 34. Furthermore, in response to the processing of step S56, the first transmission unit 36 ​​transmits a processing result corresponding to the erasure of data to be stored in the auxiliary storage device 14 of the information processing device 1, which is executed by the first execution unit 35. When the processing of step S57 ends, the information processing device 1 ends this process.

[0054] Here, the state of the information processing device 1 in step S54 or step S55 is a state in which the time-limited erasure standby flag is set, and no data is erased from the auxiliary storage device 14. Therefore, the contents of the process in Fig. 5 will be described with respect to the state of the information processing device 1 in which the time-limited erasure standby flag is set, that is, the process executed by the information processing device 1 in the standby state.

[0055] In step S61 shown in FIG. 5, the acquisition unit 37 acquires a predetermined condition in the standby state (step S61). Next, the third determination unit 38 determines whether or not the time-limited erasure standby flag is on in the standby state (step S62). Here, if the third determination unit 38 determines that the time-limited erasure standby flag is off in the standby state (step S62: No), the information processing device 1 ends this process. On the other hand, if the third determination unit 38 determines that the time-limited erasure standby flag is on in the standby state (step S62: Yes), the information processing device 1 proceeds to step S63.

[0056] In step S63, the second execution unit 39 executes data erasure (step S63). Then, when the data erasure is executed, the second determination unit 40 turns off the timed erasure standby flag (step S64). Then, the second transmission unit 41 transmits the processing result corresponding to the erasure of the data stored in the auxiliary storage device 14 of the information processing device 1 executed by the second execution unit 39 and the information on the predetermined condition acquired by the acquisition unit 37 (step S65). When the processing of step S65 ends, the information processing device 1 ends this processing.

[0057] As described above, the information processing device 1 according to one embodiment of the present invention includes a receiving unit 31 that receives remote instruction information indicating information regarding the erasure of data to be stored in the auxiliary storage device 14, and an execution unit that, upon receiving the remote instruction information, transitions to a standby state for executing the erasure of the data, and, in the standby state, executes the erasure of the data if predetermined conditions are satisfied.

[0058] As a result, according to this embodiment, it is possible to erase data stored in the auxiliary storage device 14 depending on whether or not an operation has been performed by a third party.

[0059] The predetermined condition includes at least one of the following: power button 18 provided on information processing device 1 has been pressed, information processing device 1 has been out of communication range for a predetermined period of time, back cover opening / closing mechanism 20 provided on information processing device 1 has been removed, and battery 19 that supplies power to information processing device 1 does not reach a predetermined capacity. This allows information processing device 1 to identify the possibility of operation by a third party when the information processing device has been lost or stolen by the user.

[0060] Furthermore, if the receiving unit 31 receives remote instruction information including an instruction to cancel data erasure before a predetermined condition is satisfied, the executing unit does not execute data erasure. As a result, for example, if the information processing device 1 that has been lost or stolen is returned to the user without any operation by a third party, data erasure from the auxiliary storage device 14 is not executed, and the information processing device can be reused immediately after it is returned to the user.

The program may be provided, for example, in a state in which it is stored in an appropriate storage medium such as a CD-ROM, or may be provided via a computer network such as the Internet.

Therefore, some modified examples of the above-described embodiment will be described below as other embodiments. Note that the following mainly describes the differences from the above-described embodiment, and a detailed description of the common points with the contents already described will be omitted.
