1. A method for processing a stolen terminal, comprising:

  • receiving a state modification message from a sending party, wherein the state modification message carries a current state of the terminal; and

    when the state modification message is legal, obtaining identity identification information of the terminal, and forwarding the state modification message carrying the identity identification information to a server, so that the server modifies a state information of the terminal stored in the server to be the current state according to the state modification message carrying the identity identification information, wherein the identity identification information comprises a hardware identification (ID) of the terminal, and the hardware ID is calculated according to the following steps;

    obtaining an international mobile equipment identity (IMEI) of the terminal, which is denoted as a first character string;

    obtaining a network card address of the terminal, wherein a character string left after non-letter and non-numeric characters in the network card address are removed is denoted as a second character string;

    obtaining a serial number of a central processing unit (CPU) of the terminal, which is denoted as a third character string;

    merging the first character string, the second character string and the third character string according to a predetermined order, and converting the merged character string into a capital format, which is denoted as a first result;

    performing a Message Digest Algorithm (MD5) calculation on the first result, to obtain a second result; and

    converting the second result into a capital format to obtain the hardware ID.
