Abstract
The mobile terminal (MT) configures an encryption module (EM) possessing opened and closed states. When EM is in opened state, MT cannot be turned on without inputting a password. When EM is in closed state, password is not needed. After MT is turned on, EM is auto set to the opened state and the encryption sign of SIM card is auto modified to 'encrypted'. When MT is normally turned off, EM is auto set to the closed state and the encryption sign of SIM card is auto modified to 'unencrypted'. However, when MT is abnormally turned off, this invention ensures effectively the info safety of SIM card and prohibits from using MT. The personal info will not leak out without password.
