Abstract

The present invention provides a mobile terminal control method and a mobile terminal. The mobile terminal comprises a baseband chip, a control chip and a control object. The control object comprisesa microphone and / or a camera, and an electronic switch for controlling the connection state between the control object and the underlying hardware of the baseband chip is arranged between the controlobject and the underlying hardware of the baseband chip. The method comprises that: when a credit application of the trusted execution environment receives a first notification sent by a target application in the Android layer, the baseband chip sends a first control instruction to the control chip according to the first notification, wherein the first notification is used to indicate that the anti-eavesdrop mode is turned on; and the control chip controls the electronic switch to be turned off according to the first control instruction, so that the control object is disconnected from the baseband chip. According to embodiments of the present invention, the security hazard of the control on the microphone and the camera performed by the existing mobile terminal is solved, and the loss andleakage of personal data and private information are avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal control method and the mobile terminal. Background technique [0002] As we all know, a microphone and a camera in a traditional mobile terminal (such as a mobile phone) are usually directly electrically connected to a baseband chip. Although some current designs can be set to turn off functions such as microphone, camera, audio recording, and video recording through software, for operating systems such as android, these are standard, open-source system interfaces, and are easily used by third-party software (including Trojan horse and virus program) to control or tamper with, so as to perform operations such as eavesdropping, secretly photographing and secretly recording. Therefore, there is a security risk in the control of the microphone and the camera by the existing mobile terminal. Contents of the invention [0003] Embodiments of the pr...
