AI Technical Summary

Technical Problem

In existing technologies, anti-tampering and anti-cheating methods for devices require a continuous power supply, are susceptible to environmental influences, and battery replacement can easily trigger a lockout. Furthermore, after disassembly, the circuitry can be replaced, making cheating undetectable.

Method used

It adopts a passive mechanical structure, utilizes a lever mechanism, pressure pins, and a contactless smart card chip, and achieves self-destruction and anti-cheating by physically destroying the chip module, combined with near-field communication to verify the authenticity of the device.

Benefits of technology

Effectively prevents device disassembly and cheating in environments without power, provides device authenticity verification, prevents counterfeiting and mislabeling, and reduces the risk of accidental locking.

Abstract

This application provides a passive anti-tampering and anti-cheating device, method, and electronic scale, belonging to the field of metrology and anti-counterfeiting technology. The invention includes a lever mechanism for amplifying pressure to pierce a chip module with a pressure pin; a pull rod for pressing a position switch, which in turn activates the lever mechanism; a pressure pin for physically damaging the chip module; the chip module includes a contactless smart card chip and a storage chip; the contactless smart card chip stores authentication data and authentication keys from a monitoring platform, and responds to encrypted commands authorized by the monitoring platform; the storage chip stores the identity information of the device to be protected, the platform's unique code, and a session key, for third-party manufacturers to read and for communication services with the monitoring platform; a pre-compression spring provides a preset distance between the pressure pin and the chip module; and a position switch monitors the assembly status of the device and outputs a position status signal from the lever mechanism. This invention provides a method for verifying whether a device is being cheated.
