Abstract

The invention provides multiple methods and devices for processing a stolen terminal. Therein, a method for processing a stolen terminal comprises: receiving a state modification message from a sending party, wherein the state modification message carries the current state of the terminal; and in a case where the state modification message is legal, forwarding the state modification message to a server, so that the server modifies the state information of the terminal stored in the server to be the current state according to the state modification message. By employing embodiments of the invention, the state information of a terminal can be modified, which solves the problem in the prior art that other identification cannot be provided to indicate whether the terminal is stolen or not, and can achieve the beneficial effects of increasing the probability of recovering a stolen terminal and effectively curbing the stealing acts.

modifying a state information of the terminal according to a state modification request carrying a hardware identification (ID) of the terminal returned when the terminal verifies that the state modification message passes, wherein 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.

8. The method as claimed in claim 7, wherein after receiving the state modification message from the sending party, the method further comprises:
