The invention provides a method for solving the authentication-loopholes of the identifying modules between the terminals and users, which includes the following steps. (a) The user-identifying module sets the initial authentication-sign when the terminal is powered on. (b) The authentication process is implemented between the user identifying module and the terminal. (c) If the authentication process succeeds, the identifying module re-set the authentication-sign to be the successful one. (d) The authentication-sign is judged when the identifying module and the network carry out the authenticating process. If it's the successful sign, the process runs normally; otherwise, it's banned that the terminal uses the identifying module. |
