The system server calculates, for each of a plurality of personal information types, a corresponding price. The system server sends, to a first message account, a plurality of messages, in which each message includes a respective advertisement of the subset of advertisements. Then the system server instructs a message device to output an indication of, for each of a plurality of types of personal information, whether a corresponding personal information value has been released.
