Electronic pricing scale cheating password recognition method, device and storage medium

Abstract

This application relates to the field of electronic price-computing scale cheating password identification technology, specifically to a method, device, and storage medium for electronic price-computing scale cheating password identification. The method includes: acquiring multiple sets of binary chip data from the electronic price-computing scale and their corresponding bus communication signals, wherein the bus communication signals include serial clock line signals and serial data line signals; assessing the data reliability based on voltage fluctuations, noise, and time-series periodic fluctuations of the bus communication signals, and calculating the degree of disorder using differences in sliding window binary arrays; combining the reliability and disorder to determine the weight of each set of chip data, and identifying the cheating password of the electronic price-computing scale through reverse analysis. This application solves the problem of inaccurate analysis caused by interference when reading data from bypass probes, guiding reverse analysis to prioritize high-reliability samples, thus improving the accuracy and efficiency of cheating password identification.
