[0085] In step S100, when the device to be protected is disassembled, the pulling rod 2 pulls the lever mechanism 1, so that the pressure ejector pin 3 pierces the chip module 4, and a self-destruction state signal is obtained.

[0091]

[0092]

[0093] As an optional implementation, referring to FIGS. 1 and 2, Figure 3 and Figure 4 When the passive anti-disassembly and anti-cheating device of the embodiment of the present application is disassembled, the self-destruction process is as follows:

[0094] When the pulling rod 2 is subjected to a vertical upward pulling force, the driving lever mechanism 1 is rotated around the fulcrum 11 through the hinged point. When the rotation angle reaches a critical value θ = 15° ± 5°, the limiting boss on the lever mechanism 1 is disengaged from the locking groove of the pulling rod 2, and mechanical decoupling separation is achieved.

[0095] As an optional embodiment, with reference to Figure 1 , the process of assembling the passive anti-disassembly and anti-cheating device of the embodiment of the present application to the shell is as follows:

[0096] The device body is usually assembled in the lower shell, and the pulling rod 2 is usually assembled in the upper shell.

[0097] When the lever mechanism 1 and the pulling rod 2 assembly are clamped in place, the pulling rod 2 presses the position switch 6, and the external control circuit obtains the state of the position switch 6 output to determine the assembly state of the lever mechanism 1 and the pulling rod 2.

[0098] As an optional embodiment, the device (passive anti-disassembly and anti-cheating device) of the embodiment of the present application can be issued to device manufacturers by a supervision platform. The supervision platform has a certain public credibility.

[0099] In order to prevent the device from being maliciously modified on the market, the device manufacturer needs to access the device to ensure that the device is supervised by the supervision platform.

[0100] Since the device has an anti-cheating feature, the platform needs to provide security detection for the device, and the external control circuit is an application circuit integrated into the device by each device manufacturer.

[0101] The manufacturer accessing the device can register the use of the device on the platform through the unique code provided by the device using the Internet.

[0102] The device of the embodiment of the present application provides the following two components on the chip module 4 for the platform:

[0103] 1. Built-in storage module: stores information such as the unique code of the device and the session key of the platform. The specific information is provided by the actual application of the platform. The main purpose is to enable the external control circuit to obtain platform information to provide business services.

[0104] 2. Secure chip card: a non-contact smart card chip, which is resistant to attacks at the hardware level and meets the standard GM / T 0045.

[0105] The process of issuing the device of the present application by the platform is as follows:

[0106] 1. Write the information such as the unique code of the platform, session key, etc. in the storage device, so that the manufacturers who access can obtain the relevant information, and can safely communicate and interact with the supervision platform.

[0107] 2. Read the card number of the secure chip card, randomly generate a key according to the card number (to achieve one card one key), and store the password in the platform private database:

[0108] (1) Write the platform authentication data for the secure chip card through the key. Use the characteristics of the "non-contact smart card chip" to ensure the uniqueness and security of the device issued, and the non-copying and modification.

[0109] (2) Session key: used for communication encryption between the device and the supervision platform on the Internet. Asymmetric encryption is adopted, and the platform generates two keys, one public and one private. The session key is the public key mainly used for encrypted information. Each time the device communicates, a random password will be generated and encrypted through the session key and given to the platform, and the platform uses the private key to decrypt the random password. The next communication can use this random password for communication.

[0110] The embodiments of the present application can solve the behavior of illegal persons casing and playing:

[0111] 1. Since the device is built-in "non-contact smart card chip", ordinary consumers can use the mobile phone with NFC to perform inspection.

[0112] 2. The specific inspection process of the consumer:

[0113] (1) The issuing platform issues an official applet with NFC capability.

[0114] (2) The consumer uses the official applet of the issuing platform to perform data interaction in the device antenna range area.

[0115] (3) The applet senses the CPU card, carries the card number, and requests the inspection instruction from the platform.

[0116] (4) If the applet cannot sense the CPU card, it means that the device is highly suspicious and has been disassembled.

[0117] (5) The platform gets the one-card-one-key key according to the card number, generates the inspection instruction for the card, and returns the applet to avoid key leakage.

[0118] (6) The applet executes the inspection instruction and returns the data of the CPU card to the platform for verification.

[0119] (7) The platform uses the key to verify and tells the applet the result. If the CPU card is not issued by the platform, it is considered that the device has cheating behavior.

[0120] (8) The applet prompts the consumer for information about the instrument, such as the manufacturer, model, pictures, and the like.

[0121] 3. The inspector checks the device:

[0122] The process of discovering the device of the present application is the same as the previous platform.

[0123] As an optional embodiment, the device of the present application provides an interface to the external control circuit:

[0124] 1. Device assembly state signal (provided by position switch 6);

[0125] 2. Built-in data reading of the device (provided by the storage chip of the security chip module 4);

[0126] 3. Self-locking signal of the external control circuit (the external control circuit receives a self-locking signal amount and enters a self-locking mode);

[0127] 4. Power input interface (the external control circuit inputs power for communication with the device).

[0128] The external control circuit reads the device information through the device data reading interface, so as to make business or show it to the inspector.

[0129] As an optional embodiment, the passive anti-disassembly and anti-cheating device of the present application is self-destroyed by physically damaging the chip module, and the device can be recycled by replacing the PCB of the chip module.

[0130] When disassembled, refer to Figure 5 The self-destruction and external control circuit self-locking process of the passive anti-disassembly and anti-cheating device of the present application, including:

[0131] Damage signal triggering: when the device shell is illegally disassembled, the pull rod 2 is driven by tension;

[0132] Lever conversion pressure: the lever mechanism 1 converts the tension into the impact force of the pressure ejector pin 3;

[0133] Physical destruction execution: the pressure ejector pin 3 pierces the PCB weak point area of the chip module 4, causing the non-contact smart card chip to be damaged and the stored data to be unrecoverable;

[0134] If the device is powered on, the device self-destruction process further includes:

[0135] Power supply link cut-off: the protection circuit immediately disconnects the external power supply to prevent short circuit;

[0136] System locking: the self-destruction state signal is transmitted to the external control circuit, so that the circuit is self-locked and the device (electronic scale) is forced to lock the weighing function.

[0137] In the above process, the passive anti-tampering and anti-cheating device of this embodiment can operate in a scenario without power. When the passive anti-tampering and anti-cheating device of this embodiment is powered on by an external control circuit, the protection circuit and self-destruct signal will be activated.
