Antitheft method for smart terminal device and smart terminal device

Abstract

The invention discloses an antitheft method for a smart terminal device and the smart terminal device. The method comprises sensing the light brightness using a light sensor mounted on the smart terminal device according to a preset sensing period; determining the smart terminal device has no incoming call and no incoming short massage, wherein a screen of the smart terminal device is locked; calculating the light brightness difference between the light brightness of the sensing period and the light brightness of the previous sensing period; locking the screen of the smart terminal device and noticing a user to input an unlock password if the light brightness difference is larger than the preset brightness threshold; sounding the alarm if a received unlock password is fault or an unlock password dose not be received within preset unlocking time. The antitheft method can raise the antitheft effect of the smart terminal device.

Description

technical field [0001] The invention relates to the technology of intelligent terminal equipment, in particular to an anti-theft method for intelligent terminal equipment and the intelligent terminal equipment. Background technique [0002] Smart terminal equipment refers to equipment with multimedia functions, which can support audio, video, and data transmission. By adopting an open operating system, it can load corresponding application programs to realize corresponding application functions, and provide a platform for application program operation and content services. , so that a large number of value-added services, such as news, weather, traffic, merchandise, application program download, music picture download, etc. can be realized based on this platform, including: videophone, conference terminal, PC and PDA with built-in multimedia functions, etc. [0003] With the development of mobile communication technology, especially 3G and 4G communication technology, the fu...

Problems solved by technology

[0006] As can be seen from the above, the existing smart terminal device anti-theft method installs the smart terminal device anti-theft program in the smart terminal device. After the SIM card of the smart terminal is replaced, the process of the smart terminal device anti-theft program detects that the IMSI has changed. Although the anti-theft strategy can be used to reduce the loss of users by locking hardware and other measures, what is achieved is post-processing after the smart terminal device is stolen. Anti-theft measures cannot be taken when the smart terminal device is stolen, and the anti-theft effect is poor; further After the thief steals the smart terminal device, if he does not change the SIM card, the anti-theft program of the smart terminal device cannot be triggered, and the thief can use the smart terminal device normally, but the anti-theft function fails, which causes losses to the user and makes the anti-theft effect poor.
