Problems solved by technology
The manufacturer’s anti-flash function is not very effective. If the manufacturer’s specific tool is lost to the user, the user can use this tool to maliciously modify the system software; or after the user cracks the root authority, he can use some Android system’s own Method to modify the software, such as dd command, etc., so as to bypass the manufacturer's specific tools to modify the system software, resulting in various problems on the phone
[0005] The two existing methods have a certain dependence on the root authority. After the user cracks the root authority, he can modify the system software at will, which will cause the system to be abnormal due to system software problems.
[0006] Therefore, the above two methods cannot guarantee the security of the system very well, and how to improve the security of the system has become a technical problem to be solved urgently.

The invention provides a system starting verifying method and device and a terminal. The system starting verifying method comprises the steps that when a system of the terminal is started, system files which need to be loaded are obtained; first verifying information is analyzed from the system files; the first verifying information and second verifying information prestored in the terminal are compared; and when comparing results are different, the fact that the system files have safety errors is hinted. According to the technical scheme, during system starting, system software-hardware information is verified, whether the user system files are modified or have errors can be hinted, and system safety can be improved.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a system startup verification method, a system startup verification device and a terminal. Background technique [0002] At present, the security protection of the system software by the Android terminal mainly includes the following two methods. [0003] First, control the software modification authority through the root authority provided by the Android system, prevent the system software from being modified, and achieve the purpose of protecting the system software. But because there are many loopholes in the Android system now, there are many tools for cracking root privileges on the Internet. Once users master the method of cracking root privileges, they can modify the system software at will. If the system software is modified, it may damage the software security of the system. , resulting in various problems of the system, such as: unable to boot, bo...
