Description

Mobile terminal anti-theft system and method

The invention relates to a mobile terminal anti-theft system and method.

At present, the anti-theft software on the market is endless. The more popular ones are 360 mobile guards, security butlers, Tencent mobile butlers and Jinshan mobile guards. However, if the thief steals the mobile phone, it will be shut down at the first time. The functions of these anti-theft software are turned off in the mobile phone. The situation will be useless.

In view of the above, it is necessary to provide a mobile terminal anti-theft system and method that can be used to prevent theft of a mobile terminal.

A mobile terminal anti-theft system, the system comprising: a judging module, configured to determine whether a user performs a shutdown operation on the mobile terminal; and a receiving module, configured to display and receive when determining that the user wants to perform a shutdown operation on the mobile terminal The window is configured to receive a password input by the user; and the execution module is configured to control the speaker of the mobile terminal to play a warning sound when the password input by the user is incorrect and the number of input password errors exceeds the limit.

A mobile terminal anti-theft method, the method comprising: a determining step of determining whether a user performs a shutdown operation on the mobile terminal; and a receiving step of displaying a receiving window to receive a user input when determining that the user wants to perform a shutdown operation on the mobile terminal The first execution step of controlling the speaker of the mobile terminal to play a warning tone when the password entered by the user is incorrect and the number of times the password is entered exceeds the limit.

Compared with the prior art, the mobile terminal anti-theft system and method can prevent an illegal user from shutting down the mobile terminal on the one hand, and the mobile terminal user can search for the lost mobile terminal in the first time by using the caller tracking. On the other hand, when the illegal user does not input the correct shutdown password, it can alert the user through the control of the speaker of the mobile terminal to further alert the user that the mobile terminal is stolen, in order to recover the user's loss as much as possible.

As shown in FIG. 1, it is an operating environment diagram of the anti-theft system of the present invention. In this embodiment, the anti-theft system 10 operates in the mobile terminal 1, and the mobile terminal 1 can be an electronic device such as a mobile phone. The anti-theft system 10 is configured to control the speaker 20 of the mobile terminal 1 to play a warning tone to remind the user that the mobile terminal 1 is stolen when an illegal user steals the mobile terminal 1 and wants to evade tracking by the user through shutdown. The mobile terminal 1 further includes a memory 30 and a processor 40.

The memory 30 is used to store various materials, such as a stylized code that stores the anti-theft system 10. In this embodiment, the memory 30 can also be used to store a personalized warning sound document set by the user, for example, an audio file in a format such as MP3 or WAV. The anti-theft system 10 can be segmented into one or more modules that are stored in the memory 30 and executed by the processor 40 to perform the functions provided by the present invention. For example, as shown in FIG. 2, the anti-theft system 10 is divided into a setting module 11, a judging module 12, a receiving module 13, a shutdown module 14, and an execution module 15. The module referred to in the present invention is a program segment for performing a specific function, and the functions of each module will be specifically described in the flowchart of FIG.

3 is a flow chart of a preferred embodiment of the anti-theft method of the present invention.

In step S1, the setting module 11 sets the anti-theft parameter of the mobile terminal 1 according to the needs of the user, and the anti-theft parameter includes the shutdown password of the mobile terminal 1, the warning tone, and the volume of the speaker 20 for playing the warning tone. level.

Specifically, in order to enhance the anti-theft performance of the mobile terminal 1, the shutdown password may be set more complicated, for example, a password composed of letters and numbers. In addition, in order to enable the mobile terminal 1 to issue a warning sound of a large volume to alert the user when the mobile terminal 1 is stolen, the volume level at which the speaker 20 emits a warning tone can be set to be the highest.

In step S2, the determining module 12 determines whether the user wants to perform a shutdown operation on the mobile terminal 1, and if so, performs step S3, otherwise continues to determine whether the user wants to perform a shutdown operation on the mobile terminal 1.

Specifically, if the user presses the shutdown button of the mobile terminal 1 for a preset time, it is determined that the user wants to perform a shutdown operation on the mobile terminal 1, and then step S3 is performed.

In step S3, the receiving module 13 displays the receiving window to receive the password input by the user.

For example, a receiving window can be displayed on the screen of the mobile terminal 1 and the user is prompted to input a shutdown password to shut down the mobile terminal 1.

In step S4, the determining module 12 determines whether the password input by the user is the same as the preset shutdown password, that is, whether the password input by the user is correct. If yes, step S5 is performed; otherwise, step S6 is performed.

In step S5, the shutdown module 14 shuts down the mobile terminal 1.

In step S6, the determining module 12 further determines whether the number of times the user consecutively enters the password error exceeds the limit. For example, when the number of consecutively entering the password error exceeds the limit of the number of times (for example, three times), the current user is determined to be an illegal user. S7. Conversely, if the number of times the user enters the password error has not exceeded the limit of the number of times, the process returns to step S3 to continue receiving the password input by the user.

In step S7, the execution module 15 controls the speaker 20 of the mobile terminal 1 to play the preset warning tone at a preset volume level.

It should be noted that, in order to enhance the anti-theft measure to the mobile terminal 1, the execution module 15 may be configured to display the receiving window after the receiving module 13 displays the receiving window, if the user fails to input the correct time within the preset time. The shutdown password controls the speaker 20 to play the preset warning tone at a preset volume level.

It can be seen from the process steps of the present invention that, in one aspect, the present invention can prevent an illegal user from shutting down the mobile terminal 1 so that the user of the mobile terminal 1 can search for the mobile terminal 1 in the first time by using the caller tracking. On the other hand, when the illegal user does not input the correct shutdown password, it can further alert the user that the mobile terminal 1 is stolen by controlling the speaker 20 of the mobile terminal 1 to sound the alarm to recover the user's loss as much as possible.

The above embodiments are only used to illustrate the technical solutions of the present invention, and the present invention is not limited thereto. The present invention will be described in detail with reference to the preferred embodiments, and those skilled in the art should understand that the technical solutions of the present invention may be modified or substituted. Without departing from the spirit and scope of the technical solutions of the present invention.
