Abstract

A method, an apparatus, and a system for controlling an intelligent device are provided. The device transmits a control request including a first intelligent device identifier corresponding to a first intelligent device to be controlled. In response to transmitting the control request, the device receives a first verification character string that corresponds to the control request. The first verification character string is transmitted to a first wearable device locally establishing a data connection with the first wearable device. First signed information is received from the first wearable device. The first signed information is a result of performing a signature on first to-be-signed information and includes the first verification character string. The first signed information and operation information for controlling the first intelligent device are transmitted.
