The present invention will be described in detail below with reference to the drawings and specific embodiments.

Embodiment 1

According to the first aspect of the embodiments of the present invention, an anti-theft method is provided, which is applied to a mobile terminal. As shown in FIG. 1, the anti-theft method includes:

Step S101: Listening to an appointment matching signal sent by an electronic device at a first preset time interval;

Step S103: When the appointment matching signal is not detected within the second preset time, the anti-theft operation is triggered.

In the anti-theft method provided by the embodiment of the present invention, the mobile terminal can actively monitor the appointment matching signal sent by the electronic device at the first predetermined time interval. When the mobile terminal can detect the appointment matching signal, the mobile terminal is in a safe state. When the mobile terminal does not detect the appointment matching signal within the second preset time, the anti-theft operation is triggered to protect the mobile terminal.

Therefore, the accuracy in the anti-theft process is ensured, and the occurrence of false alarms is avoided, and the anti-theft operation of the mobile terminal is not triggered casually, causing panic to the user, and at the same time, the mobile terminal can be well protected. .

However, in actual use, the request signal monitored by the mobile terminal is not necessarily an appointment matching signal. Therefore, the request signal sent by the electronic device is acquired, and it is determined whether the request signal is an agreed matching signal. Wherein, as shown in FIG. 2, when determining whether the request signal is an appointment matching signal, the following steps are mainly performed:

Step S207: When the safety sign information in the request signal and the pre-stored safety sign information are successfully matched, determining that the request signal is an appointment matching signal.

In the embodiment of the present invention, the identity information is Mobile Equipment International Identity (IMEI) information or International Mobile Subscriber Identity (IMSI) information or Media Access Control (MAC) address. Therefore, the authentication of the electronic device is unique, so after the identity information of the electronic device passes the authentication, it may be initially identified whether the request signal is from the bound device. However, with the development of technology, it is possible to clone the identity information of the electronic device. Therefore, in order to ensure the accuracy of the judgment as much as possible, it is necessary to further match the security flag information in the request signal only when the request is made. When the security flag information in the signal is successfully matched with the pre-stored security flag information, it is determined that the request signal is an appointment matching signal originating from the bound device. Therefore, the accuracy in the process of agreeing the matching signal is guaranteed, so that the present invention The anti-theft method provided by the example is more reliable.

When an abnormality occurs in the mobile terminal, the mobile terminal is triggered to perform a re-check operation.

In the actual application process, when an abnormal power failure occurs, the working flow chart of the anti-theft method is as shown in FIG. 4, and the working process is as follows:

Step S100, determining whether the mobile terminal has abnormal power failure, the determination result is yes, step S300 is performed; if the determination result is no, step S200 is performed;

Step S200: The mobile terminal does not open the burglar;

Step S300, determining whether the mobile terminal contains an emergency response battery, the determination result is yes, step S400 is performed; if the determination result is no, step S500 is performed;

Step S400 enables the battery;

Step S500: recording an abnormality flag bit, and when the abnormality flag bit is in an on state, performing a re-inspection operation after the mobile terminal is restarted;

Step S600, triggering an anti-theft operation, and performing the specific anti-theft behavior in step S700;

Step S700: Turn on the anti-theft ring; and/or invoke the short message interface to send the current location information of the mobile terminal to the electronic device; and/or perform an automatic lock screen.
