  • continuously recording the usage behavior of the computer system and generating a user'"'"'s behavioral data with a background program after the user is logged into the computer system;

    storing the user'"'"'s behavioral data in a user behavior database;

    converting the user'"'"'s behavioral data of a preset learning time into a group of articles with a first conversion program;

    creating a user'"'"'s behavioral model from the group of articles with a second conversion program;

    comparing the user'"'"'s behavioral data recorded by the background program with the user'"'"'s behavioral model at a preset time interval after the user'"'"'s behavioral model is created;

    if the similarity between the user'"'"'s behavioral data and the user'"'"'s behavioral model is below a preset threshold, the situation is determined to be an abnormal event; and

    temporarily locking the computer system and executing a revalidation process when an abnormal event occurs.
