Abstract
Description
Technical Field
[0001] This application relates to the fields of metrology and anti-counterfeiting technology, and in particular to a passive anti-tampering and anti-cheating device, method, and electronic scale. Background Technology
[0002] In the anti-tampering and anti-cheating measures of devices, active (powered) chips are usually used to store specified data. When the upper and lower shells are separated during disassembly, the power is cut off, causing the chip to lose the stored data. After reassembly, the system can detect the data loss, thereby detecting whether the device has been disassembled and locking the device.
[0003] The disadvantages of this method are as follows:
[0004] 1. Because it requires an uninterrupted power supply, the equipment is prone to short-term abnormalities during transportation or in humid environments, which can trigger the device to be locked.
[0005] 2. The device's built-in battery has a limited lifespan. Once depleted, the chip automatically "forgets" the battery, causing the device to be mistakenly locked. Replacing the battery requires disassembling the device, which can easily trigger the lockout during the replacement process.
[0006] 3. After the device is disassembled, criminals can completely replace the internal circuitry, effectively creating a counterfeit product. For example, with electronic scales, consumers cannot determine whether the scale is being cheated.
[0007] In summary, the technical problems existing in the relevant technologies need to be improved. Summary of the Invention

[0043] Before providing a detailed description of the embodiments of this application, some of the nouns and terms involved in the embodiments of this application will be explained first.

[0057] This invention takes into account that in the anti-tampering and anti-cheating of devices, active (powered) chips are usually used to store specified data. By separating the upper and lower shells during disassembly, the power is cut off, causing the chip to lose the stored data. After reassembly, the system can detect the data loss, thereby detecting whether the device has been disassembled and locking the device.
[0058] The disadvantages of this method are as follows:
[0059] 1. Because it requires an uninterrupted power supply, the equipment is prone to short-term abnormalities during transportation or in humid environments, which can trigger the device to be locked.
[0060] 2. The device's built-in battery has a limited lifespan. Once depleted, the chip automatically "forgets" the battery, causing the device to be mistakenly locked. Replacing the battery requires disassembling the device, which can easily trigger the lockout during the replacement process.
[0061] 3. After the device is disassembled, criminals can completely replace the internal circuitry, effectively creating a counterfeit product. For example, with electronic scales, consumers cannot determine whether the scale is being cheated.
[0062] There is a need to avoid the above-mentioned drawbacks, and this invention adopts a passive (no continuous power supply required) approach. This invention is designed based on the premise of being passive, and it provides consumers with a way to verify whether a device is being used fraudulently.
[0063] On one hand, embodiments of the present invention provide a passive anti-tampering and anti-cheating device, referencing... Figure 1 The device includes a lever mechanism 1, a pulling rod 2, a pressure pin 3, a chip module 4, a preload spring 5, and a position switch 6;

[0068] Position switch 6 is mounted on lever mechanism 1;
[0069] Lever mechanism 1 is used to amplify the pressure so that pressure pin 3 pierces chip module 4;
[0070] The pull rod 2 is used to press the position switch 6, which in turn activates the lever mechanism 1.
[0071] Pressure pin 3 is used to physically destroy chip module 4;

[0073] The preload spring 5 is used to provide a preset gap between the pressure pin 3 and the chip module 4;
[0074] Position switch 6 is used to monitor the assembly status of the equipment and outputs the position status signal of lever mechanism 1.
[0075] In some embodiments, the passive anti-tampering and anti-cheating device disclosed in this invention further includes a device housing; the pull rod 2 is also used to be assembled on one side of the inner housing of the device to be protected; the device housing is used to be assembled on the other side of the inner housing of the device to be protected; the other end of the preload spring 5 is used to be assembled on one side of the device housing.
[0076] In some embodiments, the lever mechanism 1 disclosed in this invention includes a power arm, a resistance arm, and a fulcrum 11.
[0077] As an optional implementation, the ratio of the power arm to the resistance arm of the lever mechanism 1 can be 3:1.
[0078] In some embodiments, the traction rod 2 disclosed in this invention is connected to the lever mechanism 1 using a bidirectional locking plug-in structure.
[0079] In some embodiments, the traction rod 2 disclosed in this invention is also used to connect an external actuator to transmit external traction force to pull the lever mechanism 1.
[0080] In some embodiments, the chip module 4 disclosed in this invention further includes a protection circuit.
[0081] As an optional implementation, the chip module 4 in this embodiment of the invention adopts a hollow PCB board design, which makes it easy for the chip module 4 to be destroyed by the pressure pin 3.
[0082] In some embodiments, the apparatus disclosed in this invention further includes a near-field communication antenna 7; the near-field communication antenna 7 is used to form a contactless CPU card with the contactless smart card chip, and to perform data interaction through an NFC card reader in a passive environment, transmitting the identity and configuration information of the device to be protected.
[0083] In some embodiments, the apparatus disclosed in this invention further includes a self-destruct mechanism base 8; the self-destruct mechanism base 8 is used to place the chip module 4 and provide travel space for the pressure pin 3.
[0084] This application also provides a passive anti-tampering and anti-cheating method, which is implemented using the passive anti-tampering and anti-cheating device described above. The method includes the following steps:
[0085] Step S100: When the device to be protected is disassembled, pull rod 2 pulls lever mechanism 1, causing pressure pin 3 to pierce chip module 4 and obtain self-destruct status signal;
[0086] Step S200: Lock the control circuit according to the self-destruct status signal.
[0087] The position switch 6 in this embodiment of the invention provides an assembly status. When the chip module 4 is damaged, it refuses to serve the peripheral control circuit, using this as a self-destruct signal, which the peripheral control circuit uses to sense that the device has been damaged.
[0088] This application also provides a passive anti-tampering and anti-cheating electronic scale. The electronic scale is a device to be protected, and the device installed in the inner shell of the electronic scale includes the aforementioned passive anti-tampering and anti-cheating device.
[0089] As an optional implementation, the passive anti-tampering and anti-cheating device of this invention includes: a lever mechanism 1, a pulling rod 2, a pressure pin 3, a chip module 4, a preload spring 5, a position switch 6, a near-field communication antenna 7, and a self-destruct mechanism base 8. (See reference) Figure 2 This is a schematic diagram of the passive anti-tampering and anti-cheating device of this invention being assembled on the upper and lower shells of the device to be protected. The pull rod 2 is installed on the upper shell (one side of the inner shell of the device to be protected) 9, and the device housing is installed on the lower shell (the other side of the inner shell of the device to be protected) 10. One end of the preload spring 5 is installed on the lever mechanism 1, and the other end of the preload spring 5 and the self-destruct mechanism base 8 are both installed on one side of the device housing. When the passive anti-tampering and anti-cheating device of this invention is installed in place, as... Figure 1 The lever mechanism 1 and the pulling rod 2 are connected by a bidirectional locking plug-in structure. The pulling rod 2 is also used to connect an external control circuit (external actuator). The external control circuit is not a circuit within this device, but refers to any external circuit connected to this device. The composition structure of the passive anti-tampering and anti-cheating device of this embodiment is defined in Table 1 below.
[0090] Table 1. Definition of the Composition and Structure of the Device
[0091]
[0092]
[0093] As an optional implementation method, refer to Figure 3 and Figure 4 The self-destruct process of the passive anti-tampering and anti-cheating device of this invention when it is disassembled:
[0094] When the pull rod 2 is subjected to a vertical upward traction force, it drives the lever mechanism 1 to rotate around the fulcrum 11 through the hinge point. When the rotation angle reaches the critical value θ = 15° ± 5°, the limiting boss on the lever mechanism 1 disengages from the locking groove of the pull rod 2, realizing mechanical decoupling.
[0095] As an optional implementation method, refer to Figure 1 The process of assembling the passive anti-tampering and anti-cheating device of this invention into the housing:
[0096] The main body of the device is usually assembled in the lower housing, and the traction rod 2 is usually assembled in the upper housing. When the traction rod 2 and the lever mechanism 1 are assembled using a two-way locking plug-in structure, the traction rod 2 in the upper housing and the two-way locking plug-in structure of the main body of the device in the lower housing are directionally locked together.
[0097] When the lever mechanism 1 and the traction rod 2 are engaged, the traction rod 2 presses against the position switch 6, and the external control circuit obtains the status output of the position switch 6 to determine the assembly status of the lever mechanism 1 and the traction rod 2.
[0098] As an optional implementation, the device (passive anti-tampering and anti-cheating device) of this invention can be issued to equipment manufacturers by the regulatory platform. The regulatory platform has a certain degree of credibility.
[0099] To prevent their equipment from being maliciously modified in the market, equipment manufacturers need to connect to this device to ensure they are monitored by the regulatory platform.
[0100] Because the device has anti-cheating features, the platform needs to provide security detection for the device, and the external control circuit is the application circuit that each equipment manufacturer integrates into the device.
[0101] Manufacturers that connect to the platform can register the usage of their devices with the platform via the unique code provided by the device.
[0102] The device of this embodiment provides the following two components on the chip module 4:
[0103] 1. Built-in storage module: Stores the device's unique code, session key, and other information on the platform. Specific information is provided by the actual platform application. Its main purpose is to enable external control circuits to obtain platform information in order to provide business services.
[0104] 2. Secure chip card: Contactless smart card chip, hardware-level anti-attack, standard GM / T 0045.
[0105] The process of distributing the device of this invention on the platform:
[0106] 1. Write the unique code, session key and other information of the storage device to the platform, so that the connected manufacturers can obtain relevant information and can communicate and interact securely with the regulatory platform.
[0107] 2. Read the security chip card number, randomly generate a key based on the card number (ensuring one key per card), and store the key in the platform's private database:
[0108] (1) Data for platform authentication is written to the secure chip card via a key. The characteristics of the "contactless smart card chip" are used to ensure the uniqueness, security, and non-copyability of the device issuance.
[0109] (2) Session Key: Used for encryption of communication between the device and the monitoring platform over the Internet. Asymmetric encryption is used, and the platform generates two keys, one public and one private. The session key is the public key and is mainly used for encrypting information. Each time the device communicates, it generates a random password, encrypts it with the session key, and sends it to the platform. The platform decrypts the random password using the private key. Subsequent communications can then use this random password.
[0110] The embodiments of the present invention can solve the problem of illegal shell and brand imitation activities:
[0111] 1. Because the device has a built-in "contactless smart card chip", ordinary consumers can use a mobile phone with NFC to verify it.
[0112] 2. Specific inspection process for consumers:
[0113] (1) The issuing platform releases an official mini-program with NFC capabilities.
[0114] (2) Consumers use the official mini-program of the issuing platform to interact with data within the device's antenna range.
[0115] (3) After the mini-program senses the CPU card, it sends a verification command to the platform with the card number.
[0116] (4) If the mini program cannot detect the CPU card, it indicates that the device is highly suspicious and has been disassembled.
[0117] (5) The platform follows up on the card number to obtain the key for each card, generates verification instructions for the card and replies to the mini program to avoid key leakage.
[0118] (6) After the mini-program executes the verification command, it sends the data returned by the CPU card to the platform for verification.
[0119] (7) The platform uses a key to verify and informs the mini-program of the result. If the CPU card is not issued by the platform, the device is considered to have engaged in cheating.
[0120] (8) The mini-program prompts consumers with information about the instrument, such as the instrument manufacturer, instrument model, pictures, etc.
[0121] 3. Inspection of the equipment by the inspectors:
[0122] The process of discovering the device of the present invention is the same as that of the previous platform.
[0123] As an optional implementation, the device of this embodiment provides an interface for an external control circuit:
[0124] 1. Assembly status signal of the device (provided via position switch 6);
[0125] 2. Built-in data reading of the device (provided via the storage chip of security chip module 4);
[0126] 3. External control circuit self-locking signal (the external control circuit receives a self-locking signal and enters self-locking mode);
[0127] 4. Power input interface (external control circuit input power for communication with the device).
[0128] The external control circuit reads device information through the device data reading interface in order to generate business data or display it to inspectors.
[0129] As an optional implementation, the passive anti-tampering and anti-cheating device of this embodiment of the invention achieves self-destruction by physically damaging the chip module, and the device can be recycled by replacing the chip module PCB.
[0130] When disassembling, refer to Figure 5 The self-destruction and external control circuit self-locking process of the passive anti-tampering and anti-cheating device of this invention includes:
[0131] Damage signal trigger: When the equipment housing is illegally disassembled, the pull rod 2 is driven by tension.
[0132] Lever-based pressure conversion: Lever mechanism 1 converts the pulling force into the impact force of the pressure pin 3;
[0133] Physical damage execution: The pressure pin 3 pierces the weak area of the PCB of the chip module 4, causing damage to the contactless smart card chip and making the stored data unrecoverable;
[0134] If the equipment is powered on, the self-destruct process also includes:
[0135] Power supply link disconnection: The protection circuit immediately disconnects the external power supply to prevent short circuit;
[0136] System Lock: The self-destruct status signal is transmitted to the external control circuit, causing the circuit to lock and forcing the device (electronic scale) 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.
[0138] As an optional implementation, the device to be protected in this embodiment of the invention can be, in addition to an electronic scale, an electricity meter, a gas meter, a medicine transport box, etc., and the device to be protected includes:
[0139] I. Metering equipment for daily life
