[0002] With the widespread use of electronic devices, the security and stability of the devices have become the focus of attention of users and manufacturers. Traditional protection measures for electronic devices are mostly focused on the network security level, ignoring the physical security of hardware devices. In fact, the physical security and information security of the equipment are equally important. During transportation, use and maintenance, the equipment often faces the risk of being illegally disassembled and illegally modified, which may not only cause damage to the equipment hardware and affect the overall function of the equipment system, but also lead to the leakage of user information privacy, thereby threatening the safety of the user's life and property. Therefore, it is particularly important to develop a security protection system that can effectively prevent the equipment from being illegally disassembled. Summary of the invention

If it is detected that the power supply status of the anti-tampering module battery to the anti-tampering component of the device is abnormal and / or the power receiving status of the anti-tampering chip to the anti-tampering component of the device is abnormal, the power supply and reception status of the anti-tampering module is determined to be an abnormal power supply and reception status.

[0014] In one embodiment, the anti-tampering chip is also configured to store an anti-tampering key, and when the power supply status of the anti-tampering machine module is determined to be an abnormal power supply status, the anti-tampering key is cleared and a device power supply stop instruction is sent to the anti-tampering power supply management module.

[0015] In one embodiment, the device system is further configured to store an anti-tampering system terminal program and, when started, to send a request to establish a communication connection to the anti-tampering machine module;

[0016] The device system is also configured to: if a communication connection cannot be established with the anti-dismantling machine module, determine that it is currently in an abnormal connection state; if a communication connection is successfully established with the anti-dismantling machine module, verify the anti-dismantling key stored in the anti-dismantling chip based on the anti-dismantling system terminal program, and if the anti-dismantling system terminal program cannot correctly detect the anti-dismantling key, determine that it is currently in an abnormal verification state.

[0017] In one embodiment, the anti-disassembly chip is also configured to: when the power supply and reception status of the anti-disassembly module is determined to be an abnormal power supply and reception status, record the current time and current positioning information as abnormal disassembly information; and after establishing a communication connection with the device system, send the abnormal disassembly information to the device system.

[0019] In one embodiment, the device system is also configured to: when started and connected to the Internet, maintain communication with the cloud-based anti-dismantling machine management system; when in an automatic locking state, if an unlocking instruction sent by the anti-dismantling machine management system is received, enter the device system unlocking program, rewrite a new terminal program based on the unlocking instruction, and send a new anti-dismantling key to the anti-dismantling chip; if it is detected that the information proofreading status between the anti-dismantling machine module and the device system is a normal proofreading status, unlock the device system.

[0022] The equipment power supply system supplies power to the anti-tampering machine module;

[0023] If the anti-disassembly machine module detects that the bidirectional power supply with the anti-disassembly component of the device is abnormal, it stops supplying power to the device system;

[0024] The device system is connected to the anti-dismantling machine module for communication. If a connection abnormality is detected, the device system enters an automatic locking state.

First, the anti-dismantling machine module is powered by the equipment power supply system. Then, if the anti-dismantling machine module detects that the two-way power supply with the equipment anti-dismantling component is abnormal, it stops powering the equipment system. Finally, the equipment system is configured to communicate with the anti-dismantling machine module. If the communication connection result is a connection abnormality, it enters an automatic locking state; if the connection is normal, the information to be verified in the anti-dismantling machine module is verified. If the verification result is a verification abnormality, it enters an automatic locking state, thereby effectively improving the safety of the equipment when facing illegal dismantling.

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means one or more, unless otherwise clearly and specifically defined.

[0039] Figure 1 The following is a schematic diagram showing a structural diagram of an anti-disassembly machine safety protection system provided by the first aspect of an embodiment of the present application. For ease of explanation, only the parts related to the present embodiment are shown, which are described in detail as follows:

[0040] The anti-disassembly machine safety protection system in this embodiment includes a device end 10 and an anti-disassembly machine module 20. The device end 10 includes: a device power supply system 101, a device anti-disassembly component 102 and a device system 103;

[0041] The device power supply system 101 is configured to supply power to the anti-tampering machine module 20;

[0042] The anti-tampering machine module 20 is configured to stop supplying power to the device system 103 if it detects that the bidirectional power supply with the device anti-tampering component 102 is abnormal;

[0043] The device system 103 is configured to establish a communication connection with the anti-dismantling machine module 20. If the communication connection result is an abnormal connection, the device enters an automatic locking state. If the connection is detected to be normal, the information to be verified in the anti-dismantling machine module 20 is verified. If the verification result is an abnormal verification, the device enters an automatic locking state.

[0044] It is understandable that, in general, the device system will be directly powered by the device power supply system, while the device power supply in the embodiment of the present application will first pass through the anti-dismantling machine module, and the anti-dismantling machine module will control whether to power the device system, ensuring that the device system will first be stopped from powering after being abnormally and illegally dismantled and cannot be started. Specifically, the anti-dismantling machine module will bidirectionally power the device anti-dismantling component to confirm whether the device anti-dismantling component has been removed. Once the device anti-dismantling component is removed, the bidirectional power supply will be abnormally disconnected, and the anti-dismantling machine module will immediately stop powering the device system. In some other cases, the device power supply system will be modified to bypass the anti-dismantling machine module and directly power the device system. At this time, the system will also start, and then try to communicate with the anti-dismantling machine module. If the anti-dismantling machine module is removed, a connection abnormality will occur, and the device system will enter an automatic locking state. If a connection is successfully established with the anti-dismantling machine module, the next step of information management verification operation will be performed. The anti-tampering machine module stores preset verification information. When an abnormality occurs in the bidirectional power supply, the verification information will be automatically cleared. If the correct verification information cannot be detected during the verification, the device system will enter an automatic locking state, thereby ensuring the safety and integrity of the equipment.

[0045] exist Figure 1 Based on the anti-disassembly machine safety protection system provided, this embodiment also provides a detailed anti-disassembly machine safety protection system structure schematic diagram, please refer to Figure 2 , in some embodiments, the anti-tampering machine module 20 includes an anti-tampering module battery 201, an anti-tampering power supply management module 202, an anti-tampering chip 203 and an anti-tampering detection circuit 204;

[0046] The device power supply system 101 is also configured to charge the anti-tamper module battery 201;

[0047] The anti-tamper module battery 201 is configured to supply power to the anti-tamper chip 203 and the anti-tamper detection circuit 204;

[0048] The anti-tampering power supply management module 202 is configured to control whether the device power supply system 101 supplies power to the device system 103 according to the power supply management instruction of the anti-tampering chip 203;

[0049] The anti-disassembly detection circuit 204 is configured to detect the power supply status of the anti-disassembly module battery 201 to the device anti-disassembly component 102 and the power receiving status of the anti-disassembly chip 203 to the device anti-disassembly component 102, and upload power supply and receiving status information including the power supply status and the power receiving status to the anti-disassembly chip 203.

[0050] It can be understood that the anti-disassembly module battery is an independent battery in the anti-disassembly module. When connected to the equipment power supply system, the battery is charged by the equipment power supply system, and the anti-disassembly module battery independently supplies power to the anti-disassembly chip and the anti-disassembly detection circuit, thus ensuring that the anti-disassembly module can work even when the power supply is cut off. The anti-disassembly module also includes an anti-disassembly power supply management module, so that the original equipment power supply system no longer directly supplies power to the equipment system, but is connected to this module, and the anti-disassembly chip controls whether this module supplies power to the equipment system. At the same time, the equipment anti-disassembly component will be electrically connected to the anti-disassembly chip and the anti-disassembly module battery, and the relevant power supply and reception status will be detected through the anti-disassembly detection circuit to ensure that the equipment anti-disassembly component has not been removed. The anti-disassembly detection circuit will also send the power supply and reception status information to the anti-disassembly chip, and the anti-disassembly chip will detect the relevant status information. If an abnormal power outage is detected, it means that the equipment anti-disassembly component may be removed, and then an instruction will be sent to control the anti-disassembly power supply management module to stop supplying power to the equipment system, ensuring the integrity of the equipment.

[0051] In some embodiments, the anti-disassembly chip is further configured to detect the power supply status information. If it is detected that the power supply status of the anti-disassembly module battery to the anti-disassembly component of the device is abnormal and / or the power receiving status of the anti-disassembly chip to the anti-disassembly component of the device is abnormal, the power supply status of the anti-disassembly machine module is determined to be an abnormal power supply status.

[0052] Specifically, the anti-dismantling chip will detect the power supply and receiving status information uploaded by the anti-dismantling detection circuit. If it is detected that the power supply status of the anti-dismantling module battery to the anti-dismantling components of the equipment is abnormal and / or the power receiving status of the anti-dismantling chip to the anti-dismantling components of the equipment is abnormal, the power supply and receiving status of the entire anti-dismantling machine module will be determined as an abnormal power supply and receiving status.

[0053] In some embodiments, the anti-tampering chip is also configured to store an anti-tampering key, and when the power supply status of the anti-tampering machine module is determined to be an abnormal power supply status, the anti-tampering key is cleared and a device power supply stop instruction is sent to the anti-tampering power supply management module.

[0054] It is understandable that the information to be verified stored in the anti-tampering chip is specifically the anti-tampering key, and the anti-tampering key will be written into the anti-tampering chip before the device leaves the factory. When the power supply and reception status of the anti-tampering module is determined to be an abnormal power supply and reception status, it indicates that the device has been illegally disassembled. At this time, the anti-tampering chip will clear the anti-tampering key and control the anti-tampering power supply management module to stop supplying power to the device system.

[0055] In some embodiments, the device system is further configured to store an anti-tampering system terminal program and, when activated, to send a request to establish a communication connection to the anti-tampering machine module;

[0056] The device system is also configured to: if a communication connection cannot be established with the anti-dismantling machine module, determine that it is currently in an abnormal connection state; if a communication connection is successfully established with the anti-dismantling machine module, verify the anti-dismantling key stored in the anti-dismantling chip based on the anti-dismantling system terminal program, and if the anti-dismantling system terminal program cannot correctly detect the anti-dismantling key, determine that it is currently in an abnormal verification state.

[0057] It is understandable that in some cases, the anti-dismantling machine module is removed after the device is modified, and the device power supply system bypasses the anti-dismantling machine module to directly power the device system. At this time, the device system can also be started. However, the anti-dismantling system terminal program will be written into the device system before leaving the factory, and the program is bound to the bottom layer of the device system. It will run automatically when the device system is started, and detect whether the anti-dismantling machine module exists. First, a request will be sent to try to establish a communication connection with the anti-dismantling machine module. If the connection cannot be successfully established, it will be determined that the current connection state is abnormal. If a communication connection is successfully established with the anti-dismantling machine module, the anti-dismantling system terminal program will further verify the anti-dismantling key stored in the anti-dismantling chip. If the anti-dismantling key has been cleared in the previous step, the anti-dismantling key cannot be correctly detected, and then it will be determined that the current state is abnormal verification.

[0058] In some embodiments, the anti-disassembly chip is further configured to: when the power supply and reception status of the anti-disassembly module is determined to be an abnormal power supply and reception status, record the current time and current positioning information as abnormal disassembly information; and when a communication connection is established with the device system, send the abnormal disassembly information to the device system.

[0059] It is understandable that an abnormal power supply and reception status means that the anti-dismantling components of the equipment may have been illegally dismantled, and the anti-dismantling chip will record relevant information such as the current dismantling time and the current location information of the equipment as abnormal dismantling information, and send this information to the equipment system when a communication connection is successfully established with the equipment system.

[0060] exist Figure 1 Based on the anti-disassembly machine safety protection system provided, this embodiment also provides another detailed structural schematic diagram of the anti-disassembly machine safety protection system, please refer to Figure 3 In some embodiments, the device system 103 is also configured to: when started and connected to the network, maintain communication with the cloud-based anti-dismantling machine management system 30; if it is in an abnormal connection state before entering the automatic locking state, send abnormal connection information to the cloud-based anti-dismantling machine management system 30; if it is in an abnormal verification state before entering the automatic locking state, send abnormal verification information and the abnormal dismantling information to the cloud-based anti-dismantling machine management system 30.

[0061] It is understandable that when the device system is started and connected to the Internet, it will maintain a communication connection with the cloud-based anti-disassembly management system to facilitate the tracking and management of the device. If an abnormality occurs in the device system during the above steps, causing the system to enter an automatic lock state, the device system will send relevant information about the abnormal state to the cloud-based anti-disassembly management system. This information includes: what abnormal state the system has, the time of abnormal disassembly, location information, etc., so that the administrator can be notified through the cloud system to contact the customer for repairs and after-sales processing.

[0062] In some embodiments, the device system is also configured to: when started and connected to the Internet, maintain communication with the cloud-based anti-dismantling machine management system; when in an automatic locking state, if an unlocking instruction sent by the anti-dismantling machine management system is received, enter the device system unlocking program, rewrite a new terminal program based on the unlocking instruction, and send a new anti-dismantling key to the anti-dismantling chip; if it is detected that the information proofreading status between the anti-dismantling machine module and the device system is a normal proofreading status, unlock the device system.

[0063] It is understandable that after the device system is locked, it can only be unlocked through the cloud-based anti-tampering machine management system. When the device system receives the unlocking command sent by the administrator through the cloud-based anti-tampering machine management system, the system will enter the unlocking program, write a new anti-tampering key to the anti-tampering chip, and write a new anti-tampering system terminal program to the device system, so that the device system and the anti-tampering machine module can successfully establish a communication connection and successfully perform verification. Finally, the device system is unlocked and resumes normal use.

[0064] When the device anti-disassembly component is disassembled, the system structure of the anti-disassembly safety protection system provided by the embodiment of the present application is as follows: Figure 4 shown.

[0065] After the device anti-disassembly component 102 is disassembled, the bidirectional power supply between the device anti-disassembly component 102 and the anti-disassembly machine module 20 is interrupted. Further, the power supply of the anti-disassembly module battery 201 to the device anti-disassembly component 102 and the power supply of the anti-disassembly chip 203 to the device anti-disassembly component 102 are interrupted. The anti-disassembly detection circuit 204 uploads the detected power supply and reception status to the anti-disassembly chip 203. The anti-disassembly chip 203 determines that the current power supply and reception status is abnormal by analyzing the power supply and reception information uploaded by the anti-disassembly detection circuit 204, and then clears the anti-disassembly key stored in the anti-disassembly chip 203, and issues an instruction to control the anti-disassembly power supply management module 202 to interrupt the power supply to the device system 103. Since the power supply of the device system 103 is actually controlled by the anti-disassembly machine module 20, after the device anti-disassembly component 102 is abnormally disassembled, the anti-disassembly machine module 20 will stop supplying power to the device system 103, and then the device system 103 will not be able to start normally, thereby ensuring the safety of the device.

[0066] On the basis of the above situation, if the anti-disassembly machine module is directly removed or the anti-disassembly machine module stops working, and the device is directly powered and started, the system structure of the anti-disassembly machine safety protection system provided in the embodiment of the present application is as follows: Figure 5 shown.

[0067] When the device power supply system 101 is forcibly cut off from the anti-disassembly machine module 20, and bypasses the anti-disassembly machine module 20 to directly power the device system 103, after the device system 103 is started, the anti-disassembly machine system terminal program bound to the bottom layer of the device system 103 will automatically run and try to establish a communication connection with the anti-disassembly machine module 20. If the anti-disassembly machine module 20 cannot be detected, the device system 103 will be recorded as an abnormal connection and enter an automatic locking state. When the device system 103 is in the startup and networking state, the device system 103 will send abnormal information to the cloud anti-disassembly machine management system 30 to notify the administrator that an abnormal disassembly has been detected. Under normal circumstances, the administrator can be contacted for after-sales maintenance and repairs, otherwise the device will not be able to continue to be used.

[0068] Furthermore, when the anti-disassembly machine module works normally, the system structure of the anti-disassembly machine safety protection system provided by the embodiment of the present application is as follows: Figure 6 shown.

[0069] When the anti-disassembly machine module 20 works normally, the device system 103 will establish a communication connection with the anti-disassembly machine module 20 after startup, and perform information management and proofreading through the anti-disassembly key stored in the anti-disassembly chip 203 and the anti-disassembly machine system terminal program stored in the device system 103. Since the anti-disassembly key in the anti-disassembly chip 203 has been cleared in the above steps and the anti-disassembly key is invalid, the anti-disassembly machine system terminal program cannot detect the correct anti-disassembly key. At this time, the device system 103 will be recorded as an abnormal check and enter an automatic lock state. In addition, when the anti-disassembly chip 203 clears the anti-disassembly key, it will record the current time and current location information, and send the relevant disassembly information to the device system after establishing a communication connection with the device system 103. Furthermore, when the device system 103 is in the startup and networking state, the device system 103 will send relevant information to the cloud anti-disassembly machine management system 30 to notify the administrator that an abnormal disassembly situation has been detected. When in the automatic locking state, any unauthorized operation will be prohibited, and it can only be unlocked through the anti-disassembly machine management system 30. Under normal circumstances, you can contact the administrator for after-sales maintenance and repair, otherwise the device will not be able to continue to be used. If the unlocking instruction sent by the anti-disassembly machine management system 30 is received, the device system unlocking program is entered, a new terminal program is rewritten based on the unlocking instruction, and a new anti-disassembly key is sent to the anti-disassembly chip 203. If it is detected that the information proofreading status of the anti-disassembly machine module 20 and the device system 103 is in a normal proofreading status, the device system 103 is unlocked and the device is restored to normal use.

[0070] Based on the above-mentioned embodiments, the anti-disassembly safety protection system provided by the present application can effectively prevent the equipment from being illegally disassembled and illegally modified, and can effectively protect the equipment safety and information privacy. At the same time, the system can respond to the disassembly behavior in real time, record the disassembly time and location information, and facilitate the tracking and management of the equipment. In addition, the system locking and remote unlocking mechanism can effectively improve the flexibility and security of equipment management.

[0072] Figure 8 The flowchart of the anti-disassembly machine safety protection method provided in the third aspect of the embodiment of the present application is shown.

[0073] Step 801: The equipment power supply system supplies power to the anti-tampering machine module;

[0074] Step 802: If the anti-tampering machine module detects that the bidirectional power supply with the anti-tampering component of the device is abnormal, it stops supplying power to the device system.

[0075] Step 803: The device system communicates with the anti-dismantling machine module. If a connection abnormality is detected, the device enters an automatic locking state, and verifies the information to be verified in the anti-dismantling machine module. If a verification abnormality is detected, the device enters an automatic locking state.
