    Abstract: A traffic anomaly detection method includes obtaining a target time series including N elements; obtaining a target parameter of the target time series, where the target parameter includes at least one of a periodic factor or a jitter density, the periodic factor represents a wave-shaped change that is presented in the target time series and that is about a long-term trend, and the jitter density represents a deviation between an actual value and a target value of the target time series within a target time; determining, from a plurality of types based on the target parameter, a first type to which the target time series belongs, where each of the types corresponds to one parameter set, and the target parameter belongs to a parameter set corresponding to the first type; and detecting an anomaly of the target time series based on a first-type decision model corresponding to the first type.

    Abstract: In a peripheral control method, a first electronic device obtains peripheral information of one or more second electronic devices. The first electronic device creates, based on the peripheral information, a peripheral agent corresponding to a peripheral of the one or more second electronic devices. The first electronic device receives, by using a first distributed input subsystem, an input event sent by a second distributed input subsystem of a target second electronic device. The input event is an event determined after the target second electronic device collects a user input operation by using a peripheral. After processing the input event by using a target peripheral agent corresponding to the target second electronic device, the first electronic device performs a corresponding target operation.

    Abstract: This application provides an unmanned aerial vehicle authentication method and an apparatus. The method includes: sending, by a communications device after determining that a type of a terminal is a UAV, authentication information of the terminal to an authentication server, so that the authentication server can perform authentication on the terminal based on the authentication information of the terminal, and therefore, the authentication server completes authentication on the terminal. In addition, the unmanned aerial vehicle is allowed to fly only after authentication on the terminal succeeds. Therefore, flight security of the unmanned aerial vehicle can be improved.
