AI Technical Summary
Technical Problem
In existing technologies, imaging devices cannot accurately determine the integrity of data transmission, leading to redundant calculations and incorrect judgments.
Method used
By generating a second dataset and second integrity data in a replaceable chip, and using external data and the first dataset to generate the second dataset and second integrity data, the main controller detects the accuracy of the second integrity data to determine the accuracy of data transmission, thus avoiding redundant calculations.
Benefits of technology
It enables correct data transmission even when the initial integrity data is compromised, avoiding redundant data transmission and calculation, and improving the accuracy and efficiency of data transmission.
