Abstract: A message filtering method and system is provided for enabling a terminal to determine whether a message is true or false. A message server and a mobile network server perform mutual authentication and negotiate with each other for a sequence code for message verification; when transmitting a message to a terminal, the message server contains the sequence code in the message; after receiving the message, the terminal transmits the sequence code to the mobile network server for verification, presents the message for the user if the verification is passed, or rejects the message if the verification is not passed. By verifying the source of a message received using a sequence code, a false message server can be prevented from spreading a false message to terminals.
