Description

[Technical field]

[0001] The present invention relates to an electronic device, a security control method, and a program. [Background technology]

[0002] A wireless communication device (e.g., a Wi-Fi router) installed as an electronic device in a home can be accessed from a terminal outside the home as long as it is within the range of radio waves. In addition, by inputting a password into a new terminal that is to be wirelessly connected to the wireless communication device, the terminal can be wirelessly connected to the wireless communication device at any time. As a result, if the password is leaked, a malicious user can input the password into a new terminal from outside the home and wirelessly connect the terminal to the wireless communication device without the user's permission at any time. In addition, even if the password is not leaked, a malicious user can use a new terminal within the range of radio waves to break the password using a method such as brute force, which tries to decrypt the password by changing the character string one by one over a long period of time, and wirelessly connect the terminal to the wireless communication device without permission.

[0003] As a countermeasure against such unauthorized wireless connections, for example, there is a method (WPS: Wi-Fi protected setup) in which a button (switch) is provided on the wireless communication device and the security level is lowered for a predetermined period of time after the button is pressed, allowing a new terminal to wirelessly connect to the wireless communication device without entering a password (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2005-175524 [Patent Document 2] Special table number 2005-521162 Summary of the Invention [Problem to be solved by the invention]

[0005] The following analysis is provided by the present inventors.

[0006] However, the above-mentioned methods require a button (switch) on the wireless communication device, and the button significantly affects the appearance of the wireless communication device.

[0007] Furthermore, one possible method for lowering the security level without significantly affecting the appearance of the wireless communication device is to apply a method in which a circuit is operated when the wearable device is worn by a person and the circuit is stopped when the device is removed (see, for example, Patent Document 2). However, such a method requires a wearable device in addition to the wireless communication device and terminal, and the configuration of the wireless communication device needs to be changed to accommodate the configuration of the wearable device, which affects versatility.

[0008] A main object of the present invention is to provide an electronic device, a security control method, and a program that can contribute to managing a state in which the security level is lowered without affecting appearance or versatility. [Means for solving the problem]

[0009] An electronic device according to a first aspect is an electronic device configured to be able to communicate with a terminal, and comprises: an attitude detection unit arranged within the electronic device and configured to detect the attitude of the electronic device; a temperature detection unit arranged within the electronic device and configured to detect a temperature at a predetermined position within the electronic device; a communication unit configured to communicate with the terminal; and a control unit configured to lower a security level and allow a new wireless connection with the terminal via the communication unit when the attitude detection unit detects an abnormal attitude of the electronic device, wherein the control unit comprises a safety function unit configured to stop at least a portion of the function of the electronic device when the temperature detection unit detects a temperature above or below a specified value while the electronic device is in the abnormal attitude, and the abnormal attitude is an attitude in which the electronic device cannot maintain operation if power is continued to be supplied to the electronic device in that attitude.

[0010] A security control method according to a second aspect is a security control method for controlling a security level of communication between a terminal and an electronic device, and includes the steps of: lowering the security level and allowing a new wireless connection with the terminal when the electronic device detects an abnormal posture of the electronic device using a posture detection unit located within the electronic device; and stopping at least a portion of the function of the electronic device when the electronic device detects a temperature above or below a specified value using a temperature detection unit located at a predetermined position within the electronic device while the electronic device remains in the abnormal posture, wherein the abnormal posture is a posture in which the electronic device cannot maintain operation if power is continued to be supplied to the electronic device in that posture.

[0011] A program relating to a third aspect is a program that causes an electronic device to execute a process for controlling the security level of communication between a terminal and an electronic device, and causes the electronic device to execute a process for lowering the security level and allowing a new wireless connection with the terminal when an attitude detection unit located within the electronic device detects an abnormal attitude of the electronic device, and a process for stopping at least a portion of the functions of the electronic device when a temperature detection unit located at a predetermined position within the electronic device detects a temperature above or below a specified value while the electronic device remains in the abnormal attitude, the abnormal attitude being an attitude in which the electronic device cannot maintain operation if power is continued to be applied to the electronic device in that attitude.

[0012] The program can be recorded in a computer-readable storage medium. The storage medium can be a non-transient medium such as a semiconductor memory, a hard disk, a magnetic recording medium, or an optical recording medium. In addition, the present disclosure can be embodied as a computer program product. The program is input to the computer device from an input device or an external device via a communication interface, stored in a storage device, drives the processor according to a predetermined step or process, and can display the processing result, including an intermediate state as necessary, at each stage via a display device, or can communicate with the outside via the communication interface. For example, a computer device for this purpose typically includes a processor, a storage device, an input device, a communication interface, and a display device as necessary, which are connectable to each other via a bus. Effect of the Invention

[0013] The first to third aspects can contribute to managing a state in which the security level is lowered without affecting the appearance or versatility. [Brief description of the drawings]

[0015] Hereinafter, the embodiments will be described with reference to the drawings. In addition, when drawing reference symbols are used in this application, they are intended to aid understanding only and are not intended to limit the present invention to the illustrated embodiment. In addition, the following embodiments are merely examples and do not limit the present invention. In addition, the connection lines between blocks in the drawings and the like referred to in the following description include both bidirectional and unidirectional. A unidirectional arrow is a schematic representation of the flow of a main signal (data) and does not exclude bidirectionality. Furthermore, although not explicitly shown in the circuit diagrams, block diagrams, internal configuration diagrams, connection diagrams, and the like shown in the present disclosure, an input port and an output port exist at the input end and output end of each connection line.

[0016] [Embodiment 1] The electronic device according to embodiment 1 will be described with reference to the drawings. Fig. 1 is a block diagram showing a schematic configuration of the electronic device according to embodiment 1. Fig. 2 is a perspective view showing a schematic external appearance of the electronic device according to embodiment 1 in a vertical arrangement and a horizontal arrangement.

[0017] The electronic device 10 is a device that incorporates heat-generating electronic components (not shown) (see FIG. 1). The electronic device 10 has a function of lowering the security level by changing the posture of the electronic device 10 (housing; not shown). The electronic device 10 has a function of wirelessly connecting a new terminal 20 to the electronic device 10 when the security level is lowered by receiving a password from the new terminal 20 to which the correct password has been input by the user's operation. The electronic device 10 may also use a function similar to WPS to wirelessly connect a new terminal 20 to the electronic device 10 without inputting a password when the security level is lowered. The electronic device 10 has a function of shutting down the operation of the electronic device 10 when the temperature at a predetermined position of the electronic device 10 becomes equal to or higher than a specified value (or when the temperature distribution becomes a predetermined distribution) after the security level is lowered. The electronic device 10 has a function of raising (returning) the security level by returning the posture of the electronic device 10 to the original position by the user. The electronic device 10 may be a device capable of switching between two or more security levels, and may be used, for example, not only as a wireless communication device such as a wireless repeater such as a Wi-Fi router or a Bluetooth (registered trademark) transmitter, but also as a smart speaker, etc. The electronic device 10 includes a posture detection unit 11, a temperature detection unit 12, a control unit 13, a communication unit 15, and a main function unit 16 within a housing.

[0018] The attitude detection unit 11 is a functional unit that detects the attitude (orientation) of the electronic device 10 (see FIG. 1). The attitude detection unit 11 is disposed (mounted, held, mounted on a mounting board, etc.) in the electronic device 10 (housing). The attitude detection unit 11 is not present on the exterior of the electronic device 10, and does not include a mechanism such as a button or a switch. For example, an acceleration sensor, a gyro sensor, an attitude sensor, an inertial sensor, a gravity sensor, etc. can be used as the attitude detection unit 11. The attitude detection unit 11 may use a dedicated element, or may be provided as part of a semiconductor integrated circuit. The attitude detection unit 11 can detect an abnormal attitude (e.g., horizontal arrangement, see FIG. 2) in which the temperature at a predetermined position in the electronic device 10 increases as time passes after the attitude is changed (from a normal attitude to an abnormal attitude), and a normal attitude (e.g., vertical arrangement, see FIG. 2) in which the temperature at the predetermined position in the electronic device 10 decreases as time passes after the attitude is changed (from a normal attitude to a normal attitude).

[0019] The temperature detection unit 12 is a functional unit that detects the temperature at a predetermined position within the electronic device 10 (housing) (see FIG. 1). The temperature detection unit 12 is disposed (mounted, held, mounted on a mounting board, etc.) within the electronic device 10 (housing). The temperature detection unit 12 may be disposed at multiple locations within the electronic device 10 to detect the temperature distribution within the electronic device 10. For example, a radiation temperature sensor, a thermistor, etc. may be used as the temperature detection unit 12, and it may be provided as part of a semiconductor integrated circuit.

[0020] The control unit 13 is a functional unit that controls the orientation detection unit 11, the temperature detection unit 12, the communication unit 15, and the main function unit 16. The control unit 13 performs a predetermined process by executing a predetermined program. The control unit 13 may utilize a part of the main function unit 16 (processor) of the electronic device 10. When the orientation detection unit 11 detects an abnormal orientation (e.g., horizontal orientation, see FIG. 2), the control unit 13 lowers the security level and permits a new wireless connection in the communication unit 15, and when the orientation detection unit 11 detects a normal orientation (e.g., vertical orientation, see FIG. 2), the control unit 13 raises (returns) the security level and rejects a new wireless connection in the communication unit 15. The control unit 13 includes a safety function unit 14 that shuts down the electronic device 10 (may stop some functions of the electronic device 10 (e.g., stop the communication function)) when the temperature detected by the temperature detection unit 12 becomes equal to or higher than a specified value. The specified value can be any temperature just before a malfunction occurs due to an increase in the temperature of the electronic device 10. Here, a case is described in which a change in the attitude of electronic device 10 causes the temperature at a predetermined position within electronic device 10 to increase, but a change in the attitude of electronic device 10 may also cause the temperature at a predetermined position within electronic device 10 to decrease, and control unit 13 may be configured to shut down electronic device 10 when the temperature detected by temperature detection unit 12 falls below a specified value.

[0021] The communication unit 15 is a functional unit that communicates with the terminal 20 (see FIG. 1). The communication unit 15 is responsible for private communication with the user's terminal 20. The communication unit 15 may be a unit that performs short-range communication, such as Wi-Fi (wireless LAN (Local Area Network)), Bluetooth (registered trademark), or NFC (Near Field Communication).

[0022] The main functional unit 16 is a functional unit that operates as the main function of the electronic device 10 (see FIG. 1). As the main functional unit 16, for example, a relay device, a speaker, a microphone, a memory, a processor, etc. may be used.

[0023] The terminal 20 is an information communication terminal used by a user (see FIG. 1). For example, a smartphone, a tablet terminal, a personal computer, etc. can be used as the terminal 20. The terminal 20 is capable of wireless communication with the electronic device 10.

[0024] Here, the vertical and horizontal arrangements of the electronic device 10 will be described. Referring to FIG. 2, the vertically arranged electronic device 10, whose normal position is the vertical arrangement (the long direction of the external configuration is vertical), is designed so that the temperature of the electronic device 10 is below a specified value due to air convection when the electronic device 10 is arranged vertically. If such an electronic device 10 is arranged in a non-normal horizontal position (the long direction is horizontal), the air convection will not be as expected, and if the horizontal arrangement continues, the temperature will exceed the specified value, and the electronic device 10 may malfunction or become overheated. To prevent this, in the first embodiment, the control unit 13 of the electronic device 10 includes a safety function unit 14 that shuts down the electronic device 10 when the temperature at a specified position in the electronic device 10 exceeds the specified value. Note that, although the vertical and horizontal arrangements of the electronic device 10 have been described here, the normal position may be horizontal and the non-normal position may be vertical, the normal position may be an arrangement with the top surface facing up and the non-normal position may be an arrangement with the top surface facing down, or other cases may be possible. Furthermore, a normal posture is a posture in which the electronic device 10 maintains operation even if power is continued to be applied to the electronic device 10 in that posture, and an abnormal posture is a posture in which operation of the electronic device 10 cannot be maintained if power is continued to be applied to the electronic device 10 in that posture.

[0025] 3, which explains the operation of the electronic device according to the embodiment 1 with reference to the drawings, is a flow chart diagram that illustrates the operation of the electronic device according to the embodiment 1. For the configuration of the electronic device, please refer to FIG. 1.

[0026] When the electronic device 10 is turned on and starts operating, either initially or after step A6, the control unit 13 of the electronic device 10 checks whether the attitude detection unit 11 has detected an abnormal attitude (e.g., horizontal placement) of the electronic device 10 (step A1). If the normal attitude is detected (NO in step A1), the process returns to step A1 after a predetermined time. If the abnormal attitude is detected because the user places the electronic device 10 in an abnormal attitude to wirelessly connect a new terminal 20 to the electronic device 10 (YES in step A1), the process proceeds to step A2.

[0027] When an abnormal posture is detected (YES in step A1), the control unit 13 of the electronic device 10 lowers the security level and permits a new wireless connection with the terminal 20 via the communication unit 15 (step A2). This allows the terminal 20 to be wirelessly connected to the electronic device 10 by the user inputting a password into the terminal 20. When the wireless connection is successful, the user returns the electronic device 10 to the normal posture.

[0028] After step A2, or if a temperature equal to or higher than the specified value is not detected (NO in step A4), the control unit 13 of the electronic device 10 checks whether the attitude detection unit 11 detects a normal attitude of the electronic device 10 (e.g., vertical placement) (step A3). If a normal attitude is detected (YES in step A3), the process proceeds to step A6. If an abnormal attitude is detected (NO in step A3) because the user forgets to return the electronic device 10 to the normal attitude, the temperature at a predetermined position of the electronic device 10 rises, so the process proceeds to step A4 to confirm this.

[0029] If an abnormal posture is detected (NO in step A3), the safety function unit 14 of the control unit 13 of the electronic device 10 checks whether the temperature detection unit 12 detects a temperature equal to or higher than a specified value (step A4). If the temperature detection unit 12 does not detect a temperature equal to or higher than the specified value (NO in step A4), the security level is kept low and the state in which a new wireless connection with the terminal 20 is permitted in the communication unit 15 is continued, and the process returns to step A3.

[0030] If the detected temperature is equal to or higher than the specified value (YES in step A4), the control unit 13 of the electronic device 10 shuts down the operation of the electronic device 10 (step A5), and then ends the operation. This prevents the electronic device 10 from continuing to operate in a state in which a new wireless connection is permitted, ensuring security.

[0031] If the normal posture is detected (YES in step A3), the control unit 13 of the electronic device 10 increases the security level and rejects new wireless connections in the communication unit 15 (step A6), and then returns to step A1.

[0032] According to embodiment 1, the posture detection unit 11 and the temperature detection unit 12 are arranged in the electronic device 10, and the safety function unit 14 is set in the control unit 13 that is originally installed in the electronic device 10, the electronic device 10 is put into an abnormal posture to lower the security level, and when the abnormal posture continues and the temperature at a predetermined position in the electronic device 10 reaches or exceeds a specified value, the electronic device 10 is shut down, thereby contributing to managing a state with a lowered security level without affecting the appearance or versatility.

[0033] Furthermore, according to embodiment 1, the period during which the electronic device 10 lowers the security level (the period during which new wireless connections are permitted) is limited to the period from when the electronic device 10 assumes an abnormal posture until the safety function is activated, thereby improving security.

[0034] Furthermore, according to the first embodiment, mechanisms (buttons, switches, etc.) that affect the appearance are not necessary, so that the number of electronic components can be reduced.

[0035] Furthermore, according to the first embodiment, there is no need to add mechanisms (buttons, switches, etc.) that affect the appearance, and there is no need to change the configuration of the terminal 20 to be wirelessly connected.

[0036] [Embodiment 2] The electronic device according to the second embodiment will be described with reference to the drawings. Fig. 4 is a block diagram showing a schematic configuration of the electronic device according to the second embodiment.

[0037] The electronic device 10 is configured to be able to communicate with a terminal 20. The electronic device 10 includes a posture detection unit 11, a temperature detection unit 12, a communication unit 15, and a control unit 13.

[0038] The posture detection unit 11 is disposed in the electronic device 10 and configured to detect the posture of the electronic device 10. The temperature detection unit 12 is disposed in the electronic device 10 and configured to detect the temperature at a predetermined position in the electronic device 10. The communication unit 15 is configured to communicate with the terminal 20. The control unit 13 is configured to lower the security level and permit a new wireless connection with the terminal 20 via the communication unit 15 when the posture detection unit 11 detects an abnormal posture of the electronic device 10. The control unit 13 includes a safety function unit 14 configured to stop at least a part of the function of the electronic device 10 when the temperature detection unit 12 detects a temperature equal to or higher than a specified value (or lower than the specified value) while the electronic device 10 is in the abnormal posture. Here, the abnormal posture is a posture in which the electronic device 10 cannot maintain its operation if the electronic device 10 is continuously energized in that posture.

[0039] According to the second embodiment, the posture detection unit 11 and the temperature detection unit 12 are arranged in the electronic device 10, and the safety function unit 14 is set in the control unit 13 originally installed in the electronic device 10, so that the electronic device 10 is put in an abnormal posture to lower the security level, and when the abnormal posture continues and the temperature at a predetermined position in the electronic device 10 reaches or exceeds a specified value, at least some of the functions of the electronic device 10 are stopped, thereby contributing to managing a state with a lowered security level without affecting the appearance or versatility.

[0040] The electronic device according to the first and second embodiments can be configured by so-called hardware resources (information processing device, computer), and can use one having the configuration shown in Fig. 5. For example, the hardware resource 100 includes a processor 101, a memory 102, a network interface 103, etc., which are connected to each other by an internal bus 104.

[0041] Note that the configuration shown in Fig. 5 is not intended to limit the hardware configuration of the hardware resource 100. The hardware resource 100 may include hardware (e.g., an input / output interface) that is not shown. Furthermore, the number of units such as the processor 101 included in the device is not intended to be limited to the example shown in Fig. 5, and for example, multiple processors 101 may be included in the hardware resource 100. For example, a CPU (Central Processing Unit), an MPU (Micro Processor Unit), a GPU (Graphics Processing Unit), etc. can be used as the processor 101.

[0042] The memory 102 may be, for example, a random access memory (RAM), a read only memory (ROM), a hard disk drive (HDD), a solid state drive (SSD), or the like.

[0043] The network interface 103 may be, for example, a LAN (Local Area Network) card, a network adapter, a network interface card, or the like.

[0044] The functions of the hardware resource 100 are realized by the above-mentioned processing module. The processing module is realized, for example, by the processor 101 executing a program stored in the memory 102. The program can be updated by downloading it via a network or by using a storage medium storing the program. Furthermore, the processing module may be realized by a semiconductor chip. That is, it is sufficient that the functions performed by the processing module are realized by executing software on some kind of hardware.
