DETAILED DESCRIPTION

[0073] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0074] In our daily lives, electronic devices provide users with convenient services such as communication, search, and shopping. Since different services are provided by corresponding applications, these applications need to access users' private data to distinguish between different users. Since applications are installed on electronic devices, these devices store users' private data. However, due to their small size, electronic devices can become lost when not in use, leading to private data leaks.

[0075] In the related art, an electronic device is provided, such as Figure 1As shown, the electronic device includes a control module 10, a protection module 20 and a battery BAT. The enable end of the control module 10 is electrically connected to the control end of the protection module 20. The protection module 20 is electrically connected between the battery BAT and the power supply end of the control module 10. Among them, the protection module 20 includes a fuse. After the electronic device is lost, the user can remotely lock the electronic device through the cloud. After the electronic device is locked, the control module 10 controls the protection module 20 to fuse, so that the battery BAT cannot supply power to the control module 10 to prevent the user's privacy data from being leaked. However, if the electronic device is disassembled before being locked, the control module 10 can be set so that the protection module 20 is always turned on, and the battery BAT can supply power to the control module 10, resulting in the leakage of the user's privacy data, and the electronic device has a low security problem.

[0076] Based on this, the present disclosure provides a security protection device, which can change the state of a trigger signal if the electronic device is disassembled after being lost. Alternatively, if a user remotely locks the electronic device, the state of the trigger signal can change. After determining that the state of the trigger signal has changed, the security module controls the protection module to disconnect the control module and the security module and / or the control module and the functional part, thereby disabling the function of the control module. Due to the disabling of the function of the control module, the privacy data in the electronic device cannot be leaked, thereby improving the security of the electronic device. At the same time, since it is difficult to set the security module after the electronic device leaves the factory, replacing the control module with the security module to control the protection module can reliably disable the function of the control module, thereby further improving the security of the electronic device.

[0077] An exemplary embodiment of the present disclosure provides a safety protection device, such as Figure 2-1 and Figure 2-2 As shown, the safety protection device includes a control module 10, a protection module 20, and a safety module 30. A first terminal of the safety module 30 is electrically connected to a control terminal of the protection module 20, and a second terminal is configured to receive a trigger signal (trigger) and control whether the protection module 20 is turned on or off based on the trigger signal (trigger). The protection module 20 is electrically connected between the control module 10 and the safety module 30, and / or between the control module 10 and the functional unit 40 of the electronic device.

[0078] In this embodiment, the safety protection device includes a control module, a protection module, and a security module. The protection module is electrically connected between the control module and the security module and / or between the control module and the functional unit, and the security module is electrically connected to the control end of the protection module. The security module controls the protection module to be turned on or off based on the received trigger signal, so that the control module and the security module and / or the control module and the functional unit are connected or disconnected, thereby enabling or disabling the function of the control module. Since the state of the trigger signal changes when the electronic device is disassembled or locked by the user, disabling the function of the control module by the security module can prevent the leakage of private data in the electronic device, thereby improving the safety of the electronic device. At the same time, since it is difficult to set the security module after the electronic device leaves the factory, using the security module to control the protection module can reliably disable the function of the control module, thereby further improving the safety of the electronic device.

[0079] For example, the functional part 40 may be a part of the electronic device that is highly relevant to the user's private data.

[0080] In one embodiment, the protection module 20 is electrically connected between the first terminal of the control module 10 and the third terminal of the safety module 30 .

[0081] In this embodiment, after receiving the user's authentication information, the control module encrypts the authentication information and sends the encrypted authentication information to the security module for verification. By electrically connecting the protection module between the first terminal of the control module and the third terminal of the security module, the security module is unable to receive and verify the authentication information after the electronic device is disassembled, rendering the electronic device inoperable. This protects the user's private data and improves the security of the electronic device.

[0082] In one embodiment, Figure 3 As shown, the functional unit 40 includes a power supply 50 . The protection module 20 is electrically connected between the second terminal of the control module 10 and the power supply 50 .

[0083] In this embodiment, by electrically connecting the protection module between the second end of the control module and the power supply, the power supply cannot power the electronic device after the electronic device is disassembled, making the electronic device unable to start up, thereby protecting the user's privacy data and improving the security of the electronic device.

[0084] For example, the power supply 50 can be provided by a battery of the electronic device. When the battery is electrically connected to the control module 10 via a charging module, the protection module 20 can be electrically connected between the charging module and the control module 10 to prevent the leakage of user privacy data when the electronic device is powered on via an external charging device.

[0085] In one embodiment, Figure 4As shown, the functional portion 40 includes a ground terminal 60 . The protection module 20 is electrically connected between the third terminal of the control module 10 and the ground terminal 60 .

[0086] In this embodiment, by electrically connecting the protection module between the third end of the control module and the ground end, the power supply cannot power the electronic device after the electronic device is disassembled, making the electronic device unable to start up, thereby protecting the user's privacy data and improving the security of the electronic device.

[0087] In one embodiment, the functional portion 40 includes a display module. The protection module 20 is electrically connected between the fourth terminal of the control module 10 and the display module.

[0088] In this embodiment, by electrically connecting the protection module between the fourth end of the control module and the display module, the electronic device cannot display information after being disassembled, thereby protecting the user's privacy data and improving the security of the electronic device.

[0089] In one embodiment, the functional unit 40 includes a storage module. The protection module 20 is electrically connected between the fifth terminal of the control module 10 and the storage module.

[0090] In this embodiment, by electrically connecting the protection module between the fifth terminal of the control module and the storage module, the private data in the electronic device cannot be accessed after the electronic device is disassembled, thereby protecting the user's private data and improving the security of the electronic device.

[0091] For example, when the protection module 20 is electrically connected between the control module 10, the security module 30, and the plurality of functional units 40, it is possible to prevent some protection modules 20 from failing and leaking the user's private data, thereby improving the security of the electronic device.

[0092] In one embodiment, the security module 30 includes a security encryption module 31 and a security protection module 32. The first terminal of the security encryption module 31 is configured to receive a trigger signal. The first terminal of the security protection module 32 is electrically connected to the second terminal of the security encryption module 31, and the second terminal of the security protection module 32 is electrically connected to the control terminal of the protection module 20. The security encryption module 31 is configured to control the state of the security protection module 32, thereby enabling the security protection module 32 to control whether the protection module 20 is turned on or off.

[0093] In this embodiment, the security module includes a security encryption module and a security protection module, and the security encryption module is electrically connected to the security protection module. Because the security encryption module can decrypt the encrypted authentication information sent by the control module and verify the authentication information to determine whether to control the security protection module to protect the electronic device, the user's privacy data is protected to improve the security of the electronic device. The security encryption module can receive a trigger signal and control the state of the security protection module based on the trigger signal, so that the security protection module controls whether the protection module is turned on or off. Because it is difficult to set the security encryption module and the security protection module after the electronic device leaves the factory, the security encryption module controls the security protection module to control the protection module, and the function of the control module can be reliably disabled to improve the security of the electronic device.

[0094] For example, the security module 30 may include a secure element (SE). The secure element of the security protection device may be a secure element of an electronic device. By reusing the secure element of an electronic device, the number of components in the security protection device can be reduced, thereby reducing the complexity of the electronic device structure.

[0095] In one embodiment, the trigger signal trigger includes a pressure-sensing signal, wherein the pressure-sensing signal is used to reflect whether the electronic device where the safety protection device is located has been disassembled.

[0096] In this embodiment, since the electronic device needs to be pressed during the disassembly process, the pressure-sensing signal changes. By using the pressure-sensing signal as a trigger signal, it can be reflected whether the electronic device has been disassembled, thereby improving the reliability of the safety protection device.

[0097] In one embodiment, the trigger signal trigger includes a temperature signal, wherein the temperature signal is used to reflect whether welding occurs in the electronic device where the safety protection device is located.

[0098] In this embodiment, since the electronic device requires high-temperature soldering during disassembly, its temperature can significantly exceed that of normal operation, causing a change in the temperature signal. Using the temperature signal as a trigger signal can indicate whether the electronic device has been disassembled, thereby improving the reliability of the safety protection device.

[0099] In one embodiment, the trigger signal trigger includes a lock signal, wherein the lock signal is used to reflect whether the user remotely locks the electronic device where the security protection device is located.

[0100] In this embodiment, after a lost electronic device is lost, the user can remotely lock the device through the cloud to prevent private data leakage. This causes the lock signal received by the electronic device to change. By using the lock signal as a trigger signal, it can reflect whether the user wishes to lock the electronic device to prevent private data leakage, thereby improving the reliability of the security protection device.

[0101] Exemplarily, the trigger signal trigger includes a pressure signal, a temperature signal and a lock signal.

[0102] In one embodiment, Figure 2-1 to Figure 4 As shown, the first terminal of the control module 10 is electrically connected to the third terminal of the security module 30. The sixth terminal of the control module 10 is used to receive user authentication information, encrypt the authentication information, and send it to the security module 30. The security module 30 is also used to decrypt the encrypted authentication information and control the protection module 20 to be turned on or off based on the trigger signal and the authentication information.

[0103] In this embodiment, the control module receives user authentication information, encrypts it, and sends it to the security module, which verifies the authentication information. After decrypting the encrypted authentication information, the security module combines the trigger signal and the authentication information to control whether the protection module is on or off. By combining the trigger signal and the authentication information to control the protection module, the user can avoid accidentally disabling the control module when disassembling the electronic device for repair, thereby improving the reliability of the safety protection device.

[0104] In one embodiment, the protection module 20 includes a switch unit.

[0105] In this embodiment, since the switch unit can be turned on and off multiple times, the switch unit can be turned on again without replacing the switch unit after being turned off, thereby reducing the cost of the safety protection device.

[0106] Exemplarily, the switching unit may be a field effect transistor.

[0107] In one embodiment, the protection module 20 includes a fuse.

[0108] In this embodiment, since the fuse cannot be restored after being blown, the function of the control module can be reliably disabled after the electronic device is disassembled to avoid leakage of private data, thereby improving the security of the electronic device.

[0109] Exemplarily, the fuse may be a fuse.

[0110] In one embodiment, the control module 10 includes a processor.

[0111] In this embodiment, since the processor can process information efficiently, using the processor as a control module can increase the speed of authentication information processing so that the security module can control the protection module in a timely manner, thereby improving the reliability of the security protection device.

[0112] For example, the processor of the security protection device may be a processor of an electronic device. By reusing the processor of the electronic device, the number of components in the security protection device can be reduced, thereby reducing the complexity of the electronic device structure.

[0113] An exemplary embodiment of the present disclosure provides a safety protection device, such as Figure 5 As shown, the security protection device includes a processor 420, a switch unit 21, a security encryption module 31 and a security protection module 32. The switch unit 21 is electrically connected between the first end of the processor 420 and the third end of the security encryption module 31, and the control end is electrically connected to the second end of the security protection module 32. The first end of the security encryption module 31 is used to receive the trigger signal trigger, and the second end is electrically connected to the first end of the security protection module 32. The second end of the processor 420 can receive the user's authentication information, and encrypt the authentication information and send it to the security encryption module 31. After the security encryption module 31 decrypts the authentication information, it controls the security protection module 32 according to the authentication information and the trigger signal trigger, so that the security protection module 32 controls the switch unit 21 to be turned on or off.

[0114] An exemplary embodiment of the present disclosure further provides a security protection method, which can be applied to the above-mentioned security protection device, such as Figure 6 As shown, the security protection methods include:

[0115] S100: Acquire a trigger signal.

[0116] S200: When it is determined that the state of the trigger signal is the trigger state, control the protection module of the electronic device to be disconnected, so that the electronic device cannot output the stored target data.

[0117] In this embodiment, a trigger signal is obtained to determine whether the electronic device has been disassembled or whether the user has remotely locked the electronic device. If the trigger signal is determined to be in the triggered state, indicating that the electronic device has been disassembled or the user has locked the electronic device, the protection module is controlled to disconnect, preventing the electronic device from outputting stored target data. By controlling the protection module based on the trigger signal, the leakage of private data is prevented, thereby improving the security of the electronic device.

[0118] For example, the target data may be different depending on the location of the protection module in the electronic device. For example, the target data may be all data stored in the electronic device, user's private data, application data, operating system data, etc.

[0119] In one embodiment, the trigger signal includes a pressure signal and a temperature signal. The determination of the trigger signal as a trigger state in step S200 may be determined as follows:

[0120] When the pressure value corresponding to the pressure sensing signal is greater than the pressure threshold and / or the temperature value corresponding to the temperature signal is greater than the temperature threshold, it is determined that the state of the trigger signal is the trigger state.

[0121] In this embodiment, during the disassembly of the electronic device, both the pressure-sensing signal and the temperature signal will change. However, due to the different structures of the electronic devices, the order in which the pressure-sensing signal and the temperature signal change may be different, and it is necessary to determine the state of the trigger signal based on the pressure-sensing signal and the temperature signal. When the pressure value corresponding to the pressure-sensing signal is greater than the pressure threshold and / or the temperature value corresponding to the temperature signal is greater than the temperature threshold, the electronic device is disassembled, and the state of the trigger signal is determined to be a trigger state to control the disconnection of the protection module. By combining the pressure-sensing signal and the temperature signal to determine the state of the trigger signal, it is avoided that the protection module cannot be disconnected in a timely and reliable manner, thereby improving the safety of the electronic device.

[0122] For example, if the pressure value corresponding to the pressure signal is less than or equal to the pressure threshold, the pressure signal may be discarded. If the temperature value corresponding to the temperature signal is less than or equal to the temperature threshold, the temperature signal may be discarded. Alternatively, if the pressure value corresponding to the pressure signal is less than or equal to the pressure threshold and the temperature value corresponding to the temperature signal is less than or equal to the temperature threshold, the state of the trigger signal is determined to be the untriggered state.

[0123] For example, an electronic device is provided with a pressure sensor and a temperature sensor. The pressure sensor is used to detect a pressure signal, and the temperature sensor is used to detect a temperature signal. The pressure threshold and the temperature threshold are related to the locations where the pressure sensor and the temperature sensor are provided.

[0124] In one embodiment, the trigger signal includes a lock signal. The determination of whether the state of the trigger signal is a trigger state in step S200 can also be determined as follows:

[0125] When the level of the lock signal is the first level, it is determined that the state of the trigger signal is a trigger state.

[0126] In this embodiment, if an electronic device is lost, the user can remotely lock it via the cloud. This causes the lock signal level to change. When the lock signal level is at a first level, the user remotely locks the electronic device via the cloud and determines that the trigger signal is in the triggered state, thereby disconnecting the protection module. By determining the trigger signal state based on the lock signal, the protection module can be disconnected before the electronic device is disassembled, preventing the leakage of private data and thus improving the security of the electronic device.

[0127] For example, when the level of the lock signal is the second level, the lock signal may be discarded. Alternatively, when the level of the lock signal is the second level, the state of the trigger signal is determined to be the untriggered state.

[0128] Exemplarily, the first level and the second level are different levels. The first level can be a high level or a low level. The second level can be a low level or a high level.

[0129] Exemplarily, the trigger signal includes a pressure signal, a temperature signal, and a lock signal. The determination of the trigger signal state as the trigger state in step S200 can also be determined in the following manner:

[0130] When the pressure value corresponding to the pressure signal is greater than the pressure threshold, and / or the temperature value corresponding to the temperature signal is greater than the temperature threshold, and / or the level of the lock signal is the first level, the state of the trigger signal is determined to be the trigger state.

[0131] In one embodiment, after obtaining the trigger signal in step S100, the security protection method further includes:

[0132] When the trigger signal is in the untriggered state, the protection module is kept turned on so that the electronic device can output target data.

[0133] In this embodiment, when the trigger signal is in the untriggered state, the electronic device has not been disassembled, and the user has not locked the electronic device, the protection module remains on, allowing the electronic device to output the target data. By controlling the protection module based on the trigger signal, the normal operation of the electronic device is not affected, thereby improving the reliability of the electronic device.

[0134] In one embodiment, the security protection method further includes:

[0135] Get the user's authentication information.

[0136] The disconnection of the protection module of the control electronic device in step S200 is determined as follows:

[0137] If the authentication information is invalid, the protection module is controlled to disconnect.

[0138] When it is determined that the state of the trigger signal is a trigger state, the safety protection method further includes:

[0139] If the authentication information is valid, the protection module remains turned on.

[0140] In this embodiment, user authentication information is obtained to determine whether the user intends to disassemble the electronic device or has accidentally locked the device remotely. If the trigger signal is in the triggered state, if the authentication information is invalid, the user does not intend to disassemble the electronic device and has not accidentally locked the device, the protection module is disconnected. If the authentication information is valid, the user intends to disassemble the electronic device or has accidentally locked the device, the protection module remains connected. By combining authentication information with the trigger signal to control the protection module, the reliability of the electronic device is improved by preventing the protection module from accidentally disconnecting and affecting its use.

[0144] The acquisition trigger signal in step S100 is determined as follows:

[0145] When the operating mode is tamper-proof mode, obtain the trigger signal.

[0146] In this embodiment, before receiving a trigger signal, the operating mode of the electronic device is determined to determine whether the electronic device can be disassembled. If the operating mode is disassembly mode, the electronic device can be disassembled, and the protection module remains conductive. If the operating mode is anti-disassembly mode, the electronic device cannot be disassembled, and a trigger signal is received to control the protection module. By determining whether to receive a trigger signal based on the operating mode, the protection module is prevented from accidentally disconnecting when the electronic device is disassembled, thereby improving the reliability of the electronic device.

[0147] In one embodiment, after the control protection module is disconnected in step S200, the safety protection method further includes:

[0148] In response to the restoration operation on the security module, user authentication information is obtained.

[0149] In the event that the authentication information is invalid, the protection module is controlled to be disconnected.

[0150] When the authentication information is valid, the protection module remains turned on.

[0151] In this embodiment, after the protection module is disconnected, if the user finds the electronic device, the electronic device needs to be restored. In response to the restoration operation on the security module, the user's authentication information is obtained to determine whether the restoration operation is valid. If the authentication information is invalid, the restoration operation is invalid, and the protection module is controlled to be disconnected. If the authentication information is valid, the restoration operation is valid, and the protection module remains connected. By controlling the protection module based on the user's authentication information after the restoration operation on the security module, the electronic device can be restored while preventing the leakage of private data, thereby improving the security and reliability of the electronic device.

When the pressure value corresponding to the pressure signal is greater than the pressure threshold, and / or the temperature value corresponding to the temperature signal is greater than the temperature threshold, and / or the level of the lock signal is the first level, obtain user authentication information.

[0155] S420: If the authentication information is invalid, the protection module is controlled to be disconnected.

[0156] S430: In response to the restoration operation on the security module, obtain the user's authentication information again.

[0157] S440: When the authentication information is invalid, the protection module is controlled to be disconnected.

[0158] S450: When the authentication information is valid, keep the protection module turned on.

[0161] In this embodiment, a pressure signal, a temperature signal, and a lock signal are acquired to determine whether the electronic device has been disassembled or whether the user has remotely locked the electronic device via the cloud. When the pressure value corresponding to the pressure signal is greater than a pressure threshold, and / or the temperature value corresponding to the temperature signal is greater than a temperature threshold, and / or the level of the lock signal is a first level, the electronic device has been disassembled or locked, and the user's authentication information is acquired to determine whether the user needs to disassemble the electronic device or has mistakenly locked it. If the authentication information is invalid, the user does not need to disassemble the electronic device or has not mistakenly locked it, then the protection module is controlled to disconnect. After the user finds the electronic device and wishes to restore it for continued use, they perform a recovery operation on the security module. In response to the recovery operation on the security module, the user's authentication information is acquired again to determine whether the recovery operation is valid. If the authentication information is invalid, the recovery operation is invalid, and the protection module is controlled to disconnect. If the authentication information is valid, the recovery operation is valid, and the protection module remains conductive. When the pressure value corresponding to the pressure signal is greater than the pressure threshold, and / or the temperature value corresponding to the temperature signal is greater than the temperature threshold, and / or the level of the lock signal is the first level, if the authentication information is valid and the user needs to disassemble the electronic device or mistakenly lock it, the protection module remains on. When the pressure value corresponding to the pressure signal is less than or equal to the pressure threshold, the temperature value corresponding to the temperature signal is less than or equal to the temperature threshold, and the level of the lock signal is the second level, the electronic device is not disassembled and is not locked, and the protection module remains on. By controlling the protection module according to the trigger signal, the user's normal use is avoided from being affected and the leakage of private data is prevented, thereby improving the safety and reliability of the electronic device.
