According to the present disclosure, it is possible to provide an electronic device and a method for controlling the electronic device capable of improving security.
For example, in order to prevent the display information output to the display from being peeped by a third party, the electronic device has a function of filtering for display information.
However, since filtering for preventing peeping is manually set by a user, filtering does not work unless the user sets filtering. Therefore, even when the electronic device is used in a place where security is not ensured, the user may forget to turn on filtering function and filtering function may remain off. In addition, in a case where the user always keeps filtering on, the display information is difficult to see even in a place where security is ensured, and thus, usability is deteriorated.
In recent years, the number of users who work using an electronic device such as a laptop PC or a tablet PC at a place other than the office, for example, at home or at a client's place, for example, due to telework or a business trip has increased. For this reason, there is a demand for an electronic device capable of controlling a peeping prevention function by a third party to be turned on or off according to various places such as a place with high security or a place with low security.
Therefore, as a result of intensive studies, the present inventors have developed an electronic device that controls a function related to output of visual information according to a position where the electronic device is used, and have reached the present disclosure.

An operation of electronic device 10, that is, an example of a method for controlling electronic device 10 will be described with reference to
As illustrated in
In step S11, electronic device 10 communicates with external device 20. Electronic device 10 acquires the position information acquired by external device 20 by performing near field communication with external device 20. In the present specification, the position information acquired by external device 20 is referred to as “first position information”.
Specifically, external device 20 acquires the first position information by the sensor of external device 20. External device 20 transmits the first position information to electronic device 10. Electronic device 10 receives the first position information from external device 20 by first communication unit 13.
In step S12, electronic device 10 determines whether or not the first position information is acquired from external device 20.
In a case where it is determined in step S12 that electronic device 10 has acquired the first position information, the processing of acquiring the position information ends. In this case, electronic device 10 determines that the position indicated by the first position information is the position where electronic device 10 is used.
In a case where it is determined in step S12 that electronic device 10 has not acquired the first position information, the processing proceeds to step S13. For example, in a case where electronic device 10 cannot communicate with external device 20 or can communicate with external device 20 but cannot receive the first position information, it is determined that the first position information is not acquired from external device 20.
Note that, in step S12, in a case where electronic device 10 has not been able to acquire the first position information for a predetermined period, the processing may proceed to step S13. Alternatively, in a case where electronic device 10 has not been able to acquire the first position information a predetermined number of times, the processing may proceed to step S13.
In step S13, electronic device 10 determines whether or not the position information of electronic device 10 has been acquired using position information detector 15 of electronic device 10. In the present specification, the position information acquired by position information detector 15 of electronic device 10 is referred to as “second position information”.
In a case where it is determined in step S13 that electronic device 10 has acquired the second position information using position information detector 15, the processing of acquiring the position information ends. In this case, electronic device 10 determines that the position indicated by the second position information is the position where electronic device 10 is used.
In a case where it is determined in step 13 that electronic device 10 has not acquired the second position information using position information detector 15, the processing returns to step S11.
As described above, in step S1, electronic device 10 acquires the position information indicating the position of electronic device 10 by performing steps S11 to S13.
Returning to
Electronic device 10 stores the security setting information in storage 12. Therefore, in step S2, electronic device 10 may acquire the security setting information by reading the security setting information from storage 12.
The security setting information is set, changed, or updated by the administrator. Electronic device 10 can set, change, or update the security setting information stored in storage 12 of electronic device 10 by acquiring the latest security setting information from server 30.
Processing of setting, changing, or updating the security setting information stored in storage 12 of electronic device 10 will be described with reference to
As illustrated in
In step S22, electronic device 10 acquires the security setting information from server 30. Server 30 stores the security setting information set, changed, or updated by the administrator in the storage. Server 30 transmits the security setting information to electronic device 10 via the network. Electronic device 10 receives the security setting information from server 30 via the network by second communication unit 14.
In step S23, electronic device 10 stores the security setting information in storage 12.
As described above, by performing steps S21 to S23, electronic device 10 can acquire the latest security setting information and store the acquired security setting information in storage 12. Note that, steps S21 to S23 may be automatically performed at a predetermined time, or may be performed by a user's operation.
Returning to
In step S31, it is determined whether or not electronic device 10 is at the registered position. Electronic device 10 determines whether or not electronic device 10 is at the registered position using the position information of electronic device 10 acquired in step S1 and the security setting information acquired in step S2.
Specifically, electronic device 10 determines whether or not the position indicated by the position information of electronic device 10 acquired in step S1 is at the registered position registered in the security setting information. For example, electronic device 10 compares the position indicated by the position information with the registered position included in the security setting information. In a case where the position indicated by the position information matches the registered position, or in a case where the position indicated by the position information is within a predetermined range from the registered position, it is determined that electronic device 10 is at the registered position. The predetermined range can be arbitrarily set. For example, the predetermined range may be set in a facility, a land, or a place indicated by the registered position, or may be set in a room, a land, or a part of a place in the facility.
In a case where it is determined in step S31 that electronic device 10 is at the registered position, the processing proceeds to step S32. In a case where it is determined that electronic device 10 is not at the registered position, that is, electronic device 10 is at the unregistered position, the processing proceeds to step S33.
In step S32, electronic device 10 releases the restriction of the output of the visual information according to the security setting set for the registered position. Electronic device 10 releases the restriction of the output of the visual information according to the security setting set for the registered position determined in step S31 based on the security setting information.
In the present exemplary embodiment, the control of the output of the visual information is control of on or off of filtering for the display information output to display 16, and the registered position is a workplace or the like where security is ensured. Therefore, in the security setting information, filtering is set to off for the registered position.
In step S32, in a case where electronic device 10 is at the registered position, the electronic device controls filtering to be turned off according to the security setting of the security setting information. As a result, filtering can be automatically turned off in a place where security is ensured, and usability is improved for the user.
In step S33, electronic device 10 restricts the output of the visual information in a case where the electronic device is at the unregistered position. Electronic device 10 controls filtering for the display information output to display 16 to be turned on. As a result, filtering is automatically turned on in a place where security is not ensured, so that peeping by a third party can be prevented even when the user does not manually set filtering, and thus, security can be improved.
As described above, in step S3, implementation of steps S31 to S33 allows the function of controlling on or off of filtering for the display information output to display 16 to be controlled according to the position of electronic device 10 as the function related to the output of the visual information.
Returning to
According to electronic device 10 of the first exemplary embodiment, the following effects can be obtained.
Electronic device 10 includes processor 11 and storage 12 that stores an instruction executed by processor 11. The instruction includes steps S1 to S3. In step S1, electronic device 10 acquires position information indicating the position of electronic device 10. In step S2, electronic device 10 acquires the security setting information indicating the security setting determined according to the position of electronic device 10. In step S3, electronic device 10 controls the function related to the output of the visual information of electronic device 10 based on the position information and the security setting information.
With such a configuration, it is possible to control the function related to the output of the visual information according to the position of electronic device 10, and thus, it is possible to improve security. For example, in a case where electronic device 10 is at a relatively high security position, electronic device 10 does not restrict the function related to the output of the visual information. On the other hand, in a case where electronic device 10 is at a relatively low security position, electronic device 10 restricts the function related to the output of the visual information. As described above, since the function related to the output of the visual information can be automatically controlled according to the position of electronic device 10, it is possible to improve security without deteriorating usability for the user. For example, as compared with a case where the user manually sets on or off of the function, it is possible to reliably restrict the function related to the output of the visual information in a place where security is not ensured.
In addition, when electronic device 10 is at a relatively high security position, the restriction of the function related to the output of the visual information is automatically released, so that power consumption caused by the function can be suppressed.
Step S3 of controlling the function related to the output of the visual information includes controlling on or off of filtering for the display information output to the screen of electronic device 10. With such a configuration, it is possible to prevent a third party from viewing the display information displayed on the screen of electronic device 10, and thus, it is possible to improve security.
For example, the information leakage risk can be reduced by setting filtering to off at the registered position registered in advance such as a company or home and forcibly setting filtering to on at a position other than the registered position. In addition, the work efficiency of the user can be improved by enhanced visibility and convenience of the user.
The security setting information includes the registered position indicating a position registered in advance and the security setting set for the registered position. Step S3 of controlling the function related to the output of the visual information includes determining whether or not electronic device 10 is at the registered position and restricting the output of the visual information according to the security setting in accordance with the determination result of whether or not electronic device 10 is at the registered position. With such a configuration, it is possible to restrict the function related to the output of the visual information according to whether or not electronic device 10 is at the registered position, and thus, it is possible to improve security while suppressing deterioration in usability.
Restricting the output of the visual information according to the security setting includes turning on filtering for the display information output to the screen of electronic device 10. With such a configuration, in a place where security is not ensured, it is possible to prevent a third party from viewing the display information displayed on the screen of electronic device 10, and thus, it is possible to improve security.
Step S3 of controlling the function related to the output of the visual information includes turning off filtering for the display information output to the screen of electronic device 10 in accordance with the determination result of whether or not electronic device 10 is at the registered position. With such a configuration, filtering can be turned off according to whether or not electronic device 10 is at the registered position. As a result, in a place where security is ensured, filtering can be turned off to improve usability. In addition, power consumption due to filtering can be reduced.
Electronic device 10 includes first communication unit 13 that communicates with external device 20 that acquires position information. Step S1 of acquiring the position information includes acquiring the position information from external device 20 by first communication unit 13. With such a configuration, based on the position information acquired by external device 20, the position information of electronic device 10 can be acquired. In addition, in a case where external device 20 is a device including the GPS with higher accuracy than position information detector 15 of electronic device 10, for example, a smartphone, electronic device 10 can acquire position information with higher accuracy.
Electronic device 10 includes position information detector 15 that acquires position information of electronic device 10. Step S1 of acquiring the position information includes acquiring the position information by position information detector 15. With such a configuration, electronic device 10 can acquire the position information by electronic device 10 alone without depending on external device 20. As a result, convenience can be improved.
The security setting information is stored in server 30 on the network. Electronic device 10 includes second communication unit 14 that communicates with server 30 via the network. The instruction includes steps S21 to S23 of acquiring the security setting information from server 30 by second communication unit 14. With such a configuration, electronic device 10 can acquire the security setting information from server 30. For example, in a case where the administrator sets, changes, or updates the security setting information stored in server 30, electronic device 10 can acquire the latest set, changed, or updated security setting information by communicating with server 30.
The instruction includes step S4 of notifying information regarding control of the function related to the output of the visual information. With such a configuration, it is possible to notify the user of the restriction or the restriction release of the function related to the output of the visual information. As a result, the usability can be improved.
Also in the control method, the program, and the computer storage medium of electronic device 10, effects similar to the above effects can be obtained.
Note that, in the present exemplary embodiment, an example has been described in which electronic device 10 is a laptop PC, but the present invention is not limited thereto. For example, electronic device 10 may be a computer such as a desktop PC or a tablet PC.
In the present exemplary embodiment, an example has been described in which first communication unit 13 and second communication unit 14 are separate bodies, but the present invention is not limited thereto. For example, first communication unit 13 and second communication unit 14 may be integrally configured.
In the present exemplary embodiment, an example has been described in which external device 20 is a smartphone, but the present invention is not limited thereto. In addition, an example has been described in which external device 20 performs near field communication with electronic device 10, but the present invention is not limited thereto. For example, external device 20 only needs to be able to perform short-distance communication with electronic device 10, and may communicate with electronic device 10 by wired communication. For example, external device 20 may be a beacon. The beacon may be fixed to a specific place, for example, a conference room or the like. In this case, electronic device 10 may not include position information detector 15 such as the GPS. Electronic device 10 may detect that electronic device 10 is at a relatively high security position by communicating with the beacon.
In the present exemplary embodiment, an example has been described in which the sensor of external device 20 can detect the position with higher accuracy than position information detector 15 of electronic device 10, but the present invention is not limited thereto. For example, the sensor of external device 20 may have lower accuracy in position detection than position information detector 15 of electronic device 10. For example, electronic device 10 may use the position information with higher position detection accuracy out of the sensor of external device 20 and position information detector 15.
In the present exemplary embodiment, an example has been described in which step S1 of acquiring the position information includes acquiring the first position information from external device 20 and acquiring the second position information by position information detector 15 of electronic device 10, but the present invention is not limited thereto. For example, in step S1, the position information may be acquired from at least one of external device 20 or position information detector 15. For example, electronic device 10 may not include position information detector 15. In this case, electronic device 10 may acquire the first position information from external device 20 and may not acquire the second position information. Alternatively, electronic device 10 may not include first communication unit 13. In this case, electronic device 10 may acquire the second position information by position information detector 15, and may not acquire the first position information by communicating with external device 20.
In the present exemplary embodiment, an example has been described in which the position information of electronic device 10 is acquired by the GPS, but the present invention is not limited thereto. For example, the position information of electronic device 10 may be acquired from an IP address, a beacon, or the like. In this case, position information detector 15 may include a circuit that specifies the position from an IP address, a beacon, or the like.
In the present exemplary embodiment, an example has been described in which step S2 of acquiring the security setting information reads the security setting information stored in storage 12, but the present invention is not limited thereto. For example, in step S2, the security setting information may be directly acquired from server 30.
In the present exemplary embodiment, an example has been described in which the set, changed, or updated security setting information is acquired from server 30, but the present invention is not limited thereto. For example, the set, changed, or updated security setting information may be stored in a computer-readable storage medium. When being connected to a computer-readable storage medium, electronic device 10 may read the security setting information from the computer-readable storage medium and store the security setting information in storage 12. In this case, electronic device 10 may not communicate with server 30.
In the present exemplary embodiment, an example has been described in which the security setting information includes the registered position and the security setting set for the registered position, but the present invention is not limited thereto. For example, the security setting may be set for each of a plurality of the registered positions.
In the present exemplary embodiment, an example has been described in which a position where security is ensured is registered as the registered position, but the present invention is not limited thereto. For example, a position with relatively low security may be registered as the registered position.
For example, a specific place where security is not ensured may be registered, and in a case where electronic device 10 is in the specific place, the function related to the output of the visual information may be restricted. For example, in a case where electronic device 10 is in a specific place, electronic device 10 may control filtering to be turned on. In addition, in a case where electronic device 10 is not in the specific place, electronic device 10 may control filtering to be turned off.
In the present exemplary embodiment, an example has been described in which the function related to the output of the visual information is the control of on or off of filtering for the display information output to display 16, but the present invention is not limited thereto. For example, the function related to the output of the visual information may be the control of on or off of the output of the display information to an external output device. In a case where electronic device 10 includes a human sensor and restricts a function based on detection information by the human sensor, the function related to the output of the visual information may be acquisition of the detection information by the human sensor. Alternatively, in a case where a function is restricted on a condition of a specific time zone when electronic device 10 accesses a specific place, a specific file, or server 30, the function related to the output of the visual information may be detection of access to a specific place, a specific file, or server 30, or timing of a specific time zone.

As illustrated in
External output port 17 is a port that outputs display information as visual information to external output device 40. External output port 17 includes, for example, a port capable of outputting display information such as HDMI (registered trademark), RGB, or USB (registered trademark).
External output device 40 is connected to electronic device 10, acquires display information from electronic device 10, and outputs the display information. External output device 40 is a device capable of outputting the display information separately from electronic device 10, and is, for example, an external display.

As illustrated in
In step S31A, electronic device 10A determines whether electronic device 10A is at the first registered position or the second registered position. In a case where electronic device 10 is at the first registered position, the processing proceeds to step S32A. In a case where electronic device 10A is at the second registered position, the processing proceeds to step S32B.
In step S32A, electronic device 10A controls filtering for the visual information to be turned on according to the first security setting.
In step S32B, electronic device 10A controls the output of the visual information to external output device 40 to be turned off according to the second security setting. In the present exemplary embodiment, electronic device 10 controls external output port 17 to be turned off in order to turn off the output of the display information to external output device 40. As a result, the output of the display information to external output device 40 is stopped.
In step S33A, electronic device 10A controls filtering to be turned off and controls output of information to external output device 40 to be turned on. In the present exemplary embodiment, electronic device 10 controls external output port 17 to be turned on in order to turn on the output of the display information to external output device 40. As a result, the display information can be output to external output device 40.
According to electronic device 10A of the second exemplary embodiment, the following effects can be obtained.
In electronic device 10A, controlling the function related to the output of the visual information includes at least one of controlling on or off of filtering for the display information output to the screen of electronic device 10A or controlling on or off of the output of the display information to external output device 40 connected to electronic device 10A. With such a configuration, when electronic device 10A is connected to external output device 40, on or off of the output of the display information to external output device 40 can be controlled according to the position of electronic device 10A. As a result, security can be further improved.
Note that, in the second exemplary embodiment, an example has been described in which the first security setting is on setting of filtering, and the second security setting is off setting of the display information output to external output device 40. However, the present invention is not limited thereto. For example, the first security setting may be off setting of the display information output to external output device 40. Alternatively, in the second security setting, both on setting of filtering and off setting of the display information output to external output device 40 may be set.
In addition, the first security setting may be off setting of filtering and on setting of the output to external output device 40. In a case where electronic device 10A is at the unregistered position, filtering may be controlled to be turned on, and the output of the display information to external output device 40 may be controlled to be turned off.
In the second exemplary embodiment, an example has been described in which external output port 17 and external output device 40 are connected by the cable, but the present invention is not limited thereto. For example, external output port 17 may include a communication port capable of outputting wireless video, and may be wirelessly connected to external output device 40. The communication port may be included in first communication unit 13 or second communication unit 14.
An electronic device according to a third exemplary embodiment of the present disclosure will be described. The third exemplary embodiment will be described mainly on the points different from the first exemplary embodiment. In the description of the third exemplary embodiment, a configuration identical or equivalent to that of the first exemplary embodiment will be denoted by the same reference mark. In addition, the description already given for the first exemplary embodiment is omitted for the third exemplary embodiment.
An example of the electronic device according to the third exemplary embodiment will be described with reference to
The third exemplary embodiment is different from the first exemplary embodiment in that electronic device 10B includes sensor 18 that acquires detection information for detecting the presence of a person, and that output of visual information is controlled based on the detection information. In addition, the third embodiment is different from the first exemplary embodiment in that acquisition of detection information by sensor 18 is stopped according to the position of electronic device 10B as an example of controlling the function related to the output of the visual information.
As illustrated in
An example of a method for controlling electronic device 10B will be described with reference to
As illustrated in
For example, in step S3A, electronic device 10B determines whether or not electronic device 10B is at the registered position. In a case where electronic device 10B is at the registered position, electronic device 10B determines to stop the acquisition of detection information by sensor 18. In a case where electronic device 10B is not at the registered position, electronic device 10B does not stop the acquisition of detection information by sensor 18.
In a case where it is determined in step S3A that the acquisition of detection information by sensor 18 is not to be stopped, the processing proceeds to S3B. In a case where it is determined that the acquisition of detection information by sensor 18 is to be stopped, the processing proceeds to S3D.
In step S3B, electronic device 10B acquires the detection information by sensor 18.
In step S3C, electronic device 10B controls the output of the visual information based on the detection information. Electronic device 10B controls on or off of filtering for display information output to display 16 as control of the output of the visual information.
For example, electronic device 10B determines whether or not there is a person around electronic device 10B based on the detection information. In a case where it is determined that there is a person around electronic device 10B, electronic device 10B sets filtering for the display information output to display 16 to on. In a case where it is determined that there is no person around electronic device 10B, electronic device 10B sets filtering for the display information output to display 16 to off.
In step S3D, electronic device 10B stops the acquisition of detection information by sensor 18. Stopping the acquisition of detection information by sensor 18 means stopping a detection function on software. That is, sensor 18 operates on the hardware, and the detection function on the software is turned off. For example, in a case where sensor 18 is a camera, a function as a camera can be used, but the detection function for detecting the presence of a person is turned off.
According to electronic device 10B of the third exemplary embodiment, the following effects can be obtained.
Electronic device 10B further includes sensor 18 that acquires the detection information for detecting the presence of a person. The instruction executed by processor 11 further includes acquiring, by sensor 18, the detection information, and controlling the output of the visual information based on the detection information. With such a configuration, it is possible to control the output of the visual information based on the detection information by sensor 18, for example, to control on or off of filtering for the display information output to display 16. For example, when it is detected that there is a third party around electronic device 10B, filtering can be set to on to prevent peeping by the third party. As a result, security can be further improved.
The control of the function related to the output of the visual information includes determining whether or not the acquisition of detection information by sensor 18 is stopped based on the position information and the security setting information, and in case of determining to stop the acquisition of detection information, stopping the acquisition of detection information by sensor 18. With such a configuration, the acquisition of detection information by sensor 18 can be stopped according to the position of electronic device 10B. As a result, power consumption of sensor 18 can be reduced. For example, in a case where electronic device 10B is in a place where security is ensured, in some cases, it is not necessary to restrict the output of the visual information. In this case, stopping of the acquisition of detection information by sensor 18 enables reduction of the power consumption of sensor 18. In addition, it is possible to prevent sensor 18 from detecting the presence of a colleague at a workplace who does not need to keep information secret and from unintentionally restricting a function when electronic device 10B is used.
Sensor 18 includes at least one of a camera, a microphone, or a proximity sensor. With such a configuration, security can be further improved.
Note that, in the present exemplary embodiment, an example has been described in which sensor 18 detects the presence of a third party, but the present invention is not limited thereto. For example, sensor 18 may detect a user who uses electronic device 10B. In this case, filtering may be set to off while sensor 18 detects the user, and filtering may be turned on while sensor 18 does not detect the user.
In the present exemplary embodiment, an example has been described in which the control of the output of the visual information is the control of on or off of filtering, but the present invention is not limited thereto. For example, the control of the output of the visual information may be control of on or off of the output of information to external output device 40.
For example, electronic device 10 may control a function related to output of visual information on condition of a specific place, time when accessing to a specific file or server 30, or a specific time zone.
