This embodiment is applicable to the case where a mobile terminal is stolen. As shown in Fig. It may include: a clock module 110, a clock switch 120 and a control module 130;

Wherein, the control module 130 is electrically connected with the clock switch 120, and the clock switch 120 is connected in series with the clock module 110; the control module 130 is used to control the clock switch 120 to disconnect from the clock module when detecting that the mobile terminal is in a stolen 110 connections.

Wherein, the control module 130 is connected with the control terminal of the clock switch 110, and is used to control the opening or closing of the clock switch 120. The control module 130 can be the CPU of the mobile terminal, or other working modules, without specific limitation. Functional modules such as the central processing unit (Central Processing Unit, CPU), radio frequency module, and wireless network (Wireless Fidelity, wifi) module in the mobile terminal all need a clock reference when they work, and there are multiple clock modules in the mobile terminal that provide clock references for the above functional modules The clock module 110 may be at least one of the CPU clock module of the mobile terminal, the clock module of the radio frequency module, and the clock module of the wifi module. When the clock switch 120 connected in series with the clock module 110 is disconnected, the functional modules that require the clock module 110 to provide a clock reference will not be able to work, such as being unable to operate the touch screen of the mobile terminal, making calls, answering calls, sending text messages or surfing the Internet. The value of the stolen terminal to the thief is greatly reduced, making it unprofitable for the thief, thereby reducing the incidence of theft of the mobile terminal.

Specifically, a clock module 110 can correspond to a clock switch 120. When the clock switch 120 connected in series with the CPU clock module of the mobile terminal is disconnected, the CPU will not work, and the display screen and touch screen of the mobile terminal will not be able to operate; After the clock switch 120 connected in series with the clock module of the radio frequency module is disconnected, the mobile terminal will not be able to perform radio frequency communication; when the clock switch 120 connected in series with the clock module of the wifi module is disconnected, the mobile terminal will not be able to access the Internet. When the mobile terminal is stolen, the control module 130 can control one or more clock switches 120 to disconnect from the corresponding clock module 110, so that the corresponding functional modules of the mobile terminal cannot work, thereby reducing the risk of the mobile terminal to the thief. value.

Wherein, the clock module 110 may include a quartz crystal oscillator or a quartz crystal resonator. Quartz crystal resonators are referred to as crystals for short, and have two output pins. Quartz crystal oscillators are referred to as crystal oscillators for short, and generally have four pins, namely power pins, ground pins, output pins, and voltage control or floating pins. Specifically, there are multiple clock modules 110 in the mobile terminal. Some clock modules 110 use quartz crystal resonators, and some clock modules 110 use quartz crystal oscillators. The clock switch 120 can be connected in series with the output transistor of the quartz crystal resonators. pin, any one of the power supply pin and the output pin of the quartz crystal oscillator.

In addition, the stolen state can be set according to the user's needs and usage habits, and is not specifically limited. Preferably, the stolen state may include at least one of the failure times of the continuous unlocking of the mobile terminal exceeding a set threshold, obtaining a remote anti-theft command, switching a Subscriber Identity Module (SubscriberIdentityModule, SIM) card, shutting down or powering off the mobile terminal. A sort of. The control module 130 can detect the number of failures of the mobile terminal to continuously perform fingerprint unlocking, pattern unlocking or password unlocking, and judge whether the number of failures exceeds a set threshold. If the number of failures exceeds the set threshold, it is determined that the mobile terminal is stolen. state. The control terminal 130 may also determine that the mobile terminal is stolen when it detects that the mobile terminal is suddenly turned off or powered off. The stolen state may also be that the control module 130 detects that the SIM card of the mobile terminal is switched or the like. Optionally, the carrier of the remote anti-theft command is a short message, or a network message, etc.

Specifically, when the mobile terminal is restarted, the clock switch 120 is closed, and if the control module 130 detects the unlocking command input by the user, the mobile terminal returns to the normal working state, so as to prevent the clock switch 120 from being caused by misoperations such as the user forgetting the unlock pattern and removing the battery. Disconnect, so that the mobile terminal can not work properly. The anti-theft instruction may be a preset anti-theft password or an answer to an anti-theft question.

An embodiment of the present invention provides a device for protecting a mobile terminal from being stolen. The device includes a clock module, a clock switch and a control module. When the control module detects that the mobile terminal is in a stolen state, the clock is controlled. The switch disconnects the connection with the clock module, which solves the problem that the existing mobile terminal anti-theft method cannot prevent the mobile terminal from being reused, reduces the value of the stolen terminal to the thief, and thus reduces the risk of the mobile terminal being stolen. incidence.

Specifically, it is possible to obtain the number of consecutive failures of the mobile terminal to perform fingerprint unlocking, pattern unlocking or password unlocking, and determine whether the number of failures exceeds a set threshold. If the number of failures exceeds the set threshold, it is determined that the mobile terminal is stolen. State: the power-on or power-on/off state of the mobile terminal can be detected, if it is detected that the mobile terminal is suddenly turned off or power-off, it can be determined that the mobile terminal is in a stolen state, and the remote anti-theft command of the mobile terminal can be obtained regularly , if the remote anti-theft instruction is acquired, then determine that the mobile terminal is in the stolen state, and may also determine that the mobile terminal is in the stolen state when it is detected that the SIM card of the mobile terminal is switched. Optionally, the carrier of the remote anti-theft command is a short message, or a network message, etc.

Step 320, when the mobile terminal is in the stolen state, control the clock switch to disconnect the clock module.
