password when a lost
mobile phone receives a shutdown instructionfrom the user; receiving and verifying the shutdown
password input by the user by means of the

password is correct, enabling the mobile phone to
shut down; if the shutdown password is wrong, enabling the mobile phone to enter an anti-theft mode; when the user inputs the correct shutdown password in the anti-theft mode, enabling the mobile phone to
shut down; storing an
