Embodiment 1
[0023] figure 1 The implementation flow of the mobile terminal security control method provided by Embodiment 1 of the present invention is shown, and the process of the method is described in detail as follows:
[0024] In step S101, after the mobile terminal system is started, the system is locked, and it is detected whether the user identification card accessed is valid, and if it is valid, the system is unlocked.
[0025] In this embodiment, after the mobile terminal (for example: mobile phone, tablet computer, etc.) system is started, in order to prevent the use of illegal users, the system is locked. Only when it is valid or legal can the system be unlocked. Wherein, the effective or legal identification card is an identification card that has been registered, key initialized and other operations in advance.
[0026] In this embodiment, the mobile terminal includes at least one identity card interface for accessing the user identity card.
[0027] In this embodiment, ...

Abstract
The invention is applied to the technical field of a mobile terminal, and provides a safety control method and a safety controlsystem of the mobile terminal. The method comprises the following steps of: starting the system, locking the system after a mobile terminal system starts, detecting whether an accessed user identification card is effective or not, and unlocking the system when the accessed user identification card is effective; running the system, detecting whether an encrypted system image file exists or not if system refreshing operation is performed during running of the system, and performing system refreshing operation after unlocking the system image file when the encrypted system image file exists; and displaying a password input interface if system application software installation operation is performed, verifying an input password, and installing application software if the verification is passed. By the safety control method and the safety control system, the safety and the controllability of the mobile terminal system can be effectively improved.
Description
technical field [0001] The invention belongs to the technical field of mobile terminals, and in particular relates to a security control method and system for a mobile terminal. Background technique [0002] With the popularity of mobile terminal devices, there are more and more types of mobile terminal operating systems. Android is an operating system developed by Google. Due to the open source nature of its code, it is being used more and more widely. [0003] However, since the original design idea of the Android operating system is an operating system based on leisure and entertainment, it has inherent defects in the security of terminal equipment. Place the system image file that needs to be refreshed in the ordinary TF. After the end user activates the refresh mode, the terminal system will automatically write the system image file in the TF card to the terminal storage device to complete the refresh of the terminal device system. There are obvious security flaws i...
