The server stores a relationship between the user identifier, the wearable device identifier, and a server authentication key. Downlink authentication information is acquired by the server. A detection instruction including the downlink authentication information and the wearable device identifier is issued to the terminal. A detection acknowledgment returned by the terminal is received by the server. The detection acknowledgment includes uplink authentication information generated by a wearable device designated in the detection instruction, according to a device authentication key and the downlink authentication information. The device authentication key is the same as, or corresponds to, the server authentication key. The user is authenticated by the server, including matching the downlink authentication information with the uplink authentication information by using the server authentication key. ## Claims ### Claim 1 A computer-implemented registration method comprising: sending, by a terminal, a wearable device registration request to a server according to an operation of a user, the wearable device registration request including a user identifier and a wearable device identifier of the user;
