Abstract: Operation information corresponds to a first operation, where the operation information includes touch information and/or posture information of a terminal device, and manages the terminal device based on a matching degree between the operation information corresponding to the first operation and a first decision model, where the first decision model is determined based on operation information of an operation performed by a first user. According to a terminal device management method, because an operation of a user is habitual, a same user (namely, the first user) may generate a large quantity of similar operations in a process of operating the terminal device. Training is performed by using a plurality of operations of the first user, and a decision model is obtained. Based on the decision model, it can be determined whether an operation is performed by the first user.
