A mobile terminal receives a user instruction for performing facial recognition to a picture displayed on the mobile terminal and highlights each human face in the picture by a corresponding face identifying object. After receiving a user selection of two or more face identifying objects and a user-inputted target attribute value for each face identifying object, the mobile terminal generates an attribute value transfer request according to the user-inputted target attribute values, facial recognition information associated with the face identifying objects, and a first user identifier associated with the mobile terminal and sends the attribute value transfer request to a remote server. The server determines a second user identifier based on the facial recognition information associated with each face identifying object and transfers a corresponding target attribute value between the first and second user identifiers when the second user identifier is on a user-relationship chain of the first user identifier.
