The invention relates to a
user management method, a storage medium, a body fat scale and a
user management system. The method comprises the following steps: receiving a
user information modification request sent by a terminal, if it is determined that a first
cloud user identifier is associated with a first local
user identifier from an association relationship between stored
cloud user identifiers and local user identifiers of the body fat scale, modifying the first
cloud user identifier according to a modification content; and modifying stored
user information corresponding to the first cloud
user identifier. Wherein the
user information modification request comprises a target
user identifier and modification content, and the target user identifier comprises a first cloud user identifier or a first local user identifier. Therefore, the user information in the local body fat scale and the user information in the
application server can be synchronously modified, the user information in the local body fat scale and the user information in the
application server are synchronously managed, the flexibility and reliability of
user management operation of the body fat scale are improved, and then the accuracy of body indexes generated by the body fat scale based on the user information can be improved.
