Data are kept not to be wiped free of simultaneously.
As shown in Figure 1, data exempt from the process of sweep-out method it is is used for rewriting system described in one embodiment of the invention when
Schematic diagram, comprising the following steps:
Step S101, whether clear when to the agency service application for obtaining system highest permission for determining rewriting system
Except the resource interface of the config set of data area content；
Implant system process when the agency service is by system brush machine, in a particular embodiment by by default file
Store to the designated position of system and replacement system correlation original, wherein the replacement system correlation original include replace it is whole
A system file only replaces part system file.
The default file is different from the configuration mapped file of system brush machine mode.In the specific embodiment of the invention, institute
Stating in default file includes the file for being named as Chimaster and NetD, is placed into the designated position " date/ of system
local/temp".The default file is stored to designated position in the case where system is in recovery mode, wherein the storage
Process is specially decompression process, and the compressed package of default file is unziped it to designated position, so that in default file
The corresponding original of associated documents covering system.The starting of the recovery mode is executed by guidance file, and guidance is corresponding
Default file is put into designated position and decompresses, wherein the guidance file can be system original, or write
The file entered, the invention is not limited in this regard.
By by default file writing system, to be implanted into the agency service.Agency service of the present invention refers specifically to
As the transfer service interacted between system process and other application process.It is well known that Root authority refers to Unix generic operation
System manager's permission of system (including Linux and Android), similar to the Administrator in Windows system
(administrator) permission；Root authority is accessible and modifies almost all of file (android system in the mobile device of user
File and user file).But since management of the current mobile terminal system for Root authority is very strict, usual situation
Lower most applications or program do not have Root authority, therefore certain operations for needing to have Root authority can not just be held
Row.In general, the highest control authority of system, i.e. Root authority can be limited for security consideration, thus be limited
It has made a lot using behavior, in order to make further allotment and control to system resource, has needed to obtain the Root authority of system.And show
There is technology to obtain Root authority by simple brush machine mode, so that the safety of system is on the hazard.Thus, the present invention is implemented
Example obtains Root authority by the way of agency service, and the highest permission of system is obtained especially by modification system signature.When it
When his application requests obtain system service, corresponding resource interface is provided by agency service, and provide several signatures, work as label
When name is verified, allow to call corresponding resource interface, realizes safer Root authority control by this method.Specifically,
The default file brush is entered ROM by recovery brush machine by the embodiment of the present invention, and recovery guides the default file to deposit
Enter the specific position of system, and guides the default file decompression to store into ROM replacement original system file, and based on modification
ROM file afterwards generates a signature, and system verifies the signature, to ensure that the system after brush machine can normally start fortune
Row.
Wherein, the agency service runs on the ccf layer of system, such as android system, including four layer architectures, respectively
Application layer, ccf layer, system Runtime Library layer and Linux inner core.The agency service is provided with the money for management system
The module of source interface access authority, in this case, when certain program process requests corresponding resource interface, usually by this
Kind of management module receives its request, this request instruction, substantially should be a kind of interface signature, be from this management module in advance to
Program process distribution, function similarly to the effect of token.Management module receives the interface comprising respective request and signs
Afterwards, which is verified, just provides corresponding resource interface to the program process after being verified.
Based on the above principles, it when carrying out the rewriting of brush machine to system, is first rewritten to the agency service application for determining
The resource interface of the config set for the region content that whether clears data when system.Wherein, the data area includes in memory headroom
All data of storage.Under normal conditions, there are a config sets in system, for deciding whether the region content that clears data,
It is verified when being restarted after system is rewritten by system, if being proved to be successful, restores and read the number of data area
According to the data in the region that clears data automatically if authentication failed.Therefore, the embodiment of the present invention is taken based on the principle to the agency
Resource interface described in request of being engaged in modifies to it in case subsequent.
Step S102, the resource interface is called, the config set is set as exempting to remove the number in rewriting system
According to region content；
The resource of the config set for the region content that whether clears data when being obtained based on above-mentioned steps for determining rewriting system
After interface, the config set is set as to exempt to remove the data area content in rewriting system.In a particular embodiment, institute
State that config set is different according to the difference of system version, still further accord with the difference of mobile terminal model and it is different.Such as three
Star galaxy note4 is different from the system of millet note, then the config set in its system is also different, and further example is such as
The system installed in Samsung galaxy note4 is modified Android4.1, after the system installed in millet note is modification
Android4.2, and the two is also not quite similar to the modification of the android system of different editions, its is customized for each self-forming
System, and it is used for the mobile phone of different model, then can be into one according to the corresponding relationship between mobile phone model and system version
Step is mapped as the relationship between mobile phone model and config set, and different config sets can be also determined by different types.

The user instruction includes diversified forms, such as order input by user, is for another example providing corresponding system rewriting
Under interface conditions, the instruction of user can be received by setting selection key, dialog box etc..User instruction is responded, is executed
The write operation of system replaces original system file to realize the rewriting of system.
Further, other embodiments of the invention further include that after the completion of system rewriting, system is restarted and restores described
The content of data area.Specifically, when the system reboot rewrited, it can be to for determining whether clear data when rewriting system
The config set of region content is verified, and then restores the content of the data area when the authentication succeeds.Due to above-mentioned steps
Through completing the modification to the config set, so as to be verified by system, to ensure that the data area is not clear
It removes, is restored and read by system.
Based on the above process, by being used to determine the region content that whether clears data when rewriting system to agency service application
Config set resource interface, obtain respective resources interface, and repair to the config set by the calling resource interface
Change, when so that the system reboot being rewritten being verified, the config set can successfully pass verifying, so that it is guaranteed that former data area
Content do not removed, be still stored in corresponding memory space, and recover after system reboot.To on the one hand keep away
On the other hand loss of data caused by exempting from user when carrying out brush machine avoids user from saving the weight of data progress in brush machine
Multiple copy procedure, simplifies the operating process of brush machine.
