1. A method for identifying cheating activities, comprising:

  • generating a historical behavior sequence according to historical behavior events of equipment or an account to be evaluated;

    calculating an entropy rate of the historical behavior sequence;

    determining a characteristic subsequence of the historical behavior sequence;

    calculating the weight value of the characteristic subsequence;

    when the entropy rate is smaller than a preset first threshold value and the weight value is larger than a preset second threshold value, identifying that the equipment or the account to be evaluated cheats during operation;

    the first threshold and/or the second threshold are obtained through training and testing of historical behavior events of sample accounts.
