before the terminal leaves factory, a safety region is arranged in the terminal, each refined safety partition is arranged in the safety region and corresponds to different system partitions of the terminal, check information of the corresponding system partition of the terminal is stored in different refined safety partitions, and particularly, the refined safety partitions can be expanded according to the attributes or functions of the different system partitions of the terminal before the terminal leaves factory.
In addition, before the terminal is turned on, only the key system partition of the terminal may be checked, or different refined security partitions of the terminal security region may only store the checking information of the key system partition, and the security region does not store the checking information of the common partition, and the key system partition generally refers to a partition storing the terminal built-in software and the system configuration file, such as an operating system partition outside the terminal kernel memory, a kernel memory Boot partition, and as described in the specific embodiment, the refined security partition of the security region may be a first refined security partition, a second refined security partition, a third refined security partition, and so on, wherein, the checking information of the terminal Boot partition may be stored in the first refined security partition, the checking information of the system partition and so on may be stored in the second refined security partition, and the refined security partitions correspond to the terminal system partition one to one, as shown in fig. 6, the refined safety partition can be further divided into refined safety sub-partitions corresponding to the sub-system partitions of the terminal system partition, such as sub-Boot partitions of the Boot partition, and the refined safety partition can be further divided into a title refined safety partition, a content refined safety partition and the like.
In addition, check information is stored in different refining partitions of the security region, the check information comprises file or program capacity size and quantity information corresponding to different system partitions of the terminal, and when the terminal is detected to be started, the file size and quantity information of the different system partitions stored in the different refining security partitions can be acquired. In addition to the check information, as shown in fig. 5, different first-type root information is stored in different refined security partitions in the security region, where the first-type root information includes first-type root identifiers, and the first-type root identifiers may be letters and the like, the first-type root values indicate the times that the system partitions corresponding to the terminals are changed or the roots are changed, and the first-type root information corresponding to different terminal system partitions is different, for example, the first-type root identifiers of the Boot partitions may be a, the first-type root values may be 0, that is, the first-type root values are 0, that indicates that the Boot partitions have not been changed, the first-type root identifiers of the system partitions may be B, the first-type root values may be 1, and that the first-type root values are 1, that the system partitions have been changed for one time and the like.

For example, if the Boot partition of the terminal corresponds to the first refined security partition in the security domain, the check information in the first refined security partition is called to check the Boot partition, and if the system partition of the terminal corresponds to the second refined security partition, the check information in the second refined security partition in the security domain of the terminal is called to check the system partition when the system partition of the terminal is checked.
The specific process of the verification is as follows: calling the number of files corresponding to the terminal system partition stored in the refined safety partition, comparing the number of files with the number of files counted by the current system partition of the terminal, calling the file capacity size corresponding to the terminal system partition stored in the refined safety partition, comparing the file capacity size with the file capacity size of the terminal system partition, when the number or size of the files in the terminal system partition is detected to be different from the number or size of the files stored in the refined safety partition of the safety partition, the verification fails, and when the number or size of the files in the terminal system partition is completely the same as the file capacity size or size stored in the refined safety partition of the safety partition, the partition is considered to be not root-free, and the verification succeeds.
