Abstract

Embodiments of the present invention disclose a method and an apparatus for controlling a communications terminal and a corresponding communications terminal, including: setting, in a communications terminal, authentication information of a subscriber identity module (SIM) change; monitoring a SIM change broadcast sent by the communications terminal, and setting, after the SIM change broadcast is monitored, the communications terminal to a locked state; and monitoring input information on the communications terminal, performing authentication and comparison, after the input information is monitored, on the input information and the set authentication information of a SIM change, and releasing, after the authentication succeeds, the locked state of the communications terminal The embodiments of the present invention can improve security of information in a communications terminal.

Claims

1. A method for controlling a communications terminal, comprising:

setting, in a communications terminal, authentication information of a subscriber identity module (SIM) change;

monitoring a SIM change broadcast sent by the communications terminal, and setting, after the SIM change broadcast is monitored, the communications terminal to a locked state; and

monitoring input information on the communications terminal, performing authentication and comparison, after the input information is monitored, on the input information and the set authentication information of a SIM change, and releasing, after the authentication succeeds, the locked state of the communications terminal.

2. The method according to claim 1, before the setting, after the SIM change broadcast is monitored, the communications terminal to a locked state, further comprising:

determining a content parameter of the SIM change broadcast, determining, if the content parameter is null, that an incorrect SIM change broadcast is monitored, and continuing to monitor a SIM change broadcast sent by the communications terminal.

3. The method according to claim 1, wherein

the setting, in a communications terminal, authentication information of a SIM change specifically comprises:

presenting a setting interface for authentication of a SIM change, prompting a user to input a character string, and storing the input character string as the authentication information of a SIM change; and

the monitoring input information on the communications terminal, and performing authentication and comparison, after the input information is monitored, on the input information and the set authentication information of a SIM change, specifically comprises;

monitoring a character string input by the user, performing, after it is monitored that the user inputs a character string, similarity comparison between the monitored character string and the stored authentication information of a SIM change, and determining, in a case in which the monitored character string is identical with the stored authentication information of a SIM change, that the authentication succeeds.

4. The method according to claim 1, wherein

the setting, in a communications terminal, authentication information of a SIM change specifically comprises:

starting an identification information capture module to capture identification information input on the communications terminal, using the identification information as an authentication sample, computing key information of the authentication sample, and storing the key information of the authentication sample as the authentication information of a SIM change; and

the monitoring input information on the communications terminal, and performing authentication and comparison, after the input information is monitored, on the input information and the set authentication information of a SIM change, specifically comprises;

starting the identification information capture module to capture identification information input on the communications terminal, computing key information of the authentication information, performing similarity comparison between the key information obtained through computation and the stored authentication information of a SIM change, and determining, in a case in which similarity between the key information and the stored authentication information of a SIM change is higher than a corresponding threshold, that the authentication succeeds.

5. The method according to claim 4, wherein the identification information is:

gesture input information, human face feature information, voice information, or fingerprint information.

6. The method according to claim 1, wherein the SIM change broadcast comprises:

a SIM replacement broadcast, or a SIM absence broadcast.

7. The method according to claim 1, wherein

the method further comprises, after the authentication succeeds:

displaying a list of options, receiving a selection instruction for the options, determining whether a selected option is the same as a preset correct option, and releasing, if same, the locked state of the communications terminal, or otherwise, keeping the locked state of the communications terminal.

8. The method according to claim 1, wherein the SIM is a SIM card.

9. An apparatus for controlling a communications terminal, comprising:

a setting module, configured to set, in a communications terminal, authentication information of a subscriber identity module (SIM) change;

a locking module, configured to monitor a SIM change broadcast sent by the communications terminal, and set, after the SIM change broadcast is monitored, the communications terminal to a locked state; and

an unlocking module, configured to monitor input information on the communications terminal, perform authentication and comparison, after the input information is monitored, on the input information and the set authentication information of a SIM change, and release, after the authentication succeeds, the locked state of the communications terminal.

10. The apparatus according to claim 9, wherein the locking module is further configured to determine, after the SIM change broadcast is monitored, a content parameter of the SIM change broadcast, determine, if the content parameter is null, that an incorrect SIM change broadcast is monitored, and continue to monitor a SIM change broadcast sent by the communications terminal without setting the communications terminal to the locked state.

11. The apparatus according to claim 9, wherein

the setting module is specifically configured to:

present a setting interface for authentication of a SIM change, prompt a user to input a character string, and store the input character string as the authentication information of a SIM change; and

the unlocking module is specifically configured to;

monitor a character string input by the user, perform, after it is monitored that the user inputs a character string, similarity comparison between the monitored character string and the stored authentication information of a SIM change, and determine, in a case in which the monitored character string is identical with the stored authentication information of a SIM change, that the authentication succeeds, and release the locked state of the communications terminal;

or otherwise, determine that the authentication fails, and keep the locked state of the communications terminal.

12. The apparatus according to claim 9, wherein the apparatus further comprises an identification information capture module,

the setting module is specifically configured to:

start the identification information capture module to capture identification information input on the communications terminal, use the identification information as an authentication sample, compute key information of the authentication sample, and store the key information of the authentication sample as the authentication information of a SIM change; and

the unlocking module is specifically configured to;

start the identification information capture module to capture identification information input on the communications terminal, compute key information of the authentication information, perform similarity comparison between the key information obtained through computation and the stored authentication information of a SIM change, and determine, in a case in which similarity between the key information and the stored authentication information of a SIM change is higher than a corresponding threshold, that the authentication succeeds, and release the locked state of the communications terminal;

or otherwise, determine that the authentication fails, and keep the locked state of the communications terminal.
