    identifying a triggering entity for the second operation as either a human or a machine based on a behavior characteristic model, wherein the behavior characteristic model includes a classifier for human operations and machine operations, and the classifier is trained based on operation samples, wherein behavioral characteristic data of the operation samples includes at least one of the following;

    operative slide time length, operative slide time length of at least one segment, center line-deviation frequency of at least one segment, average deviation distance of at least one segment, an operation triggering initial position, and an operation triggering terminal position, and wherein the identifying of the triggering entity comprises;
