For android system, brush machine is the process of formatting, in order to prevent there is bug in brush machine process, it will usually system is carried out double; two clear, namely removes buffer memory and internal storage data.So it is possible not only to make brush machine cleaner, also avoids the system that legacy data causes unstable.But this process would generally cause the loss of user data, and cannot recover, thus bring unnecessary loss to user.For these reasons, the present invention provides a kind of data to exempt from sweep-out method, is not wiped free of so that being maintained with data in system brush machine process.
As it is shown in figure 1, it exempts from the schematic flow sheet of sweep-out method for data when being used for rewriting system described in one embodiment of the invention, comprise the following steps:
Step S101, the resource interface of config set to the region content that whether clears data when being used for the agency service application obtaining system highest weight limit for determining rewriting system；
Described agency service is by implant system process during to system brush machine, in a particular embodiment by default file storing the appointment position to system and the relevant original of replacement system, the relevant original of wherein said replacement system includes replacing whole system file or only replacing part system file.
Described default file is different from the configuration mapped file of system brush machine pattern.In the specific embodiment of the invention, described default file includes the file being named as Chimaster and NetD, and it is all placed into the appointment position " date/local/temp " of system.Described default file is under recovery pattern in system and is stored to appointment position, wherein said storing process is specially decompression process, the compressed package of default file carries out decompression be reduced to specific bit and put, so that the corresponding original of the associated documents covering system in default file.The startup of described recovery pattern, by guiding file to perform, guides corresponding default file put into appointment position and decompress, and wherein, described guiding file can be system original, it is also possible to for rewriteeing the file of write, the invention is not limited in this regard.
By by default file writing system, thus implanting described agency service.Agency service of the present invention refers specifically to as transfer service mutual between system process and other application processes.It is known that Root authority refers to system manager's authority of Unix type operating system (including Linux and Android), it is similar to Administrator (manager) authority in Windows system；Root authority can access and revise almost all of file (android system file and user file) in the mobile equipment of user.But, owing to current mobile terminal system is very strict for the management of Root authority, most application or program do not possess Root authority under normal circumstances, therefore need the operation possessing Root authority just cannot perform for some.Under normal conditions, the highest control authority of system, namely Root authority can be limited for security consideration, thus limits a lot of application behavior, in order to system resource being done allotment further and controlling, it is necessary to obtain the Root authority of system.And prior art obtains Root authority by simple brush machine mode so that the safety of system is on the hazard.Thus, the embodiment of the present invention adopts the mode of agency service to obtain Root authority, obtains the highest weight limit of system especially by amendment system signature.When other application requests obtain system service, agency service provide corresponding resource interface, and some signatures are provided, when signature verification is passed through, it is allowed to call corresponding resource interface, realize safer Root authority in this way and control.Concrete, described default file brush is entered ROM by recovery brush machine by the embodiment of the present invention, recovery guides described default file to be stored in the ad-hoc location of system, and guide the decompression of described default file to store to ROM replacement original system file, and generate a signature based on amended ROM file, this signature is verified by system, to guarantee that the system after brush machine can normal startup optimization.
Wherein, described agency service runs on the ccf layer of system, such as android system, including four layer architectures, and respectively application layer, ccf layer, system Runtime Library layer and Linux inner core.The erection of described agency service has the module of the resource interface access rights for managing system, in this case, when certain program process asks corresponding resource interface, generally received its request by this management module, this request instruction, should be substantially a kind of interface signature, this management module distribute to this program process in advance, function similarly to the effect of token.This signature is verified, just provides corresponding resource interface to described program process after being verified after receiving the interface signature comprising respective request by management module.
Based on above-mentioned principle, when system being carried out brush machine and rewriteeing, the resource interface of the config set of the region content that whether clears data when being first used for determine rewriting system to described agency service application.Wherein, described data area includes all data of storage in memory headroom.Under normal circumstances, system exists a config set, is used for deciding whether the region content that clears data, is verified by system when it restarts after system is rewritten, as being proved to be successful, recover and read the data of data area, the data in the region that then automatically clears data such as authentication failed.Therefore, the embodiment of the present invention obtains described resource interface based on this principle to described proxy service request, in order to follow-up, it is modified.
Step S102, call described resource interface, described config set is set as when rewriting system and exempts to remove described data area content；

Mapping relations between described config set and each system version or type are stored in cloud server in the form of a list, in a particular embodiment, described list can be previously generated, by collecting different system versions config set corresponding to detector, its corresponding relation is stored one by one.Cloud server carries out regular update based on this presets list, increases new system version and corresponding config set, deletes the system version being eliminated and corresponding config set simultaneously.Further, described the presets list can also record the mapping relations between the corresponding config set of different type of machines.
Preferably, the resource interface of described config set is provided with the form forming signature according to preset rules.In a particular embodiment, described preset rules refers to by which kind of mode to process to generate signature to described resource interface, as adopted hash algorithm or RSA Algorithm to process resource interface to generate a string random code characterizing signature.Specifically, described signature adopts preset rules to generate described signature based on the correlated characteristic of config set information.The mode generating signature is not limited as by the present invention, and namely described preset rules includes the mode that arbitrarily can form signature, and it does not affect the realization of the present invention.Wherein, this signature is provided previously by by agency service, when the resource interface of the config set to the region content that whether clears data time described in the acquisition of described proxy service request for determining rewriting system, first verifies described signature, if signature verification success, then allow to call the resource interface of described config set.
It is further preferred that the resource interface of described config set is provided with the form forming ciphertext according to preset rules encryption.In a particular embodiment, the information such as AES, decipherment algorithm of making an appointment, wherein said enciphering and deciphering algorithm can be the method being arbitrarily capable of encryption and decryption, not as limitation of the present invention.The resource interface of the config set of the region content that whether clears data when being used for determine rewriting system to agency service application, described agency service provides the resource interface of described config set with the form of ciphertext.The decipherment algorithm that described resource interface adopts agreement is decrypted, thus obtaining corresponding resource interface.
After obtaining described resource interface, described config set is modified, set it to and exempt from the region content that clears data when rewriting system.In a particular embodiment, described config set can be one or more parameter, and one or more files, one or more instructions, they are different according to the difference of system version.Call corresponding resource interface, described config set is modified, it is ensured that when system rewrites, described data area content is not eliminated.
It is significant to note that, described system rewrite process refers specifically to the brush machine process of user operation, it is different from the process that described default file brush enters, therefore it is prohibited the content of described default file is modified in the brush machine process of user operation, the change of described default file need to by brushing the signature verification of fashionable generation at it, the process agency service of user's brush machine does not provide corresponding signature, therefore can not default file content be modified.
Step S103, in response to user instruction write for the rewriting packet of rewriting system.
Described user instruction includes various ways, such as the order inputted by user, is and for example providing corresponding system to rewrite under interface conditions, can pass through to arrange selection key, dialog box etc. and receive the instruction of user.User instruction is responded, performs the write operation of system, replace original system file to realize the rewriting of system.
Further, other embodiments of the invention also include, and after system has rewritten, system carries out restarting and recovering the content of described data area.Concrete, when the system reboot re-writed, the config set of the region content that whether clears data when being used for and determine rewriting system can be verified, then recover the content of described data area when the authentication succeeds.Owing to above-mentioned steps is complete the amendment to described config set so that it can pass through system verification, thus ensure that described data area is not eliminated, by system recovery and read.
Based on said process, the resource interface of the config set of the region content that whether clears data during by being used for determine rewriting system to agency service application, obtain respective resources interface, and by calling described resource interface, described config set is modified, so that when the system reboot being rewritten is verified, described config set can successfully pass checking, so that it is guaranteed that the content of former data area is not eliminated, still it is saved in corresponding memory space, and recovers after system reboot.Thus, avoid the loss of data that user causes when carrying out brush machine on the one hand, avoid user when brush machine to preserve the repetition copy procedure that data carry out on the other hand, simplify the operating process of brush machine.
Modularized thoughts according to computer program, the present invention exempts from sweep-out method according to aforesaid data and additionally provides the specific embodiment of a kind of mobile terminal, as shown in Figure 2, described mobile terminal includes application unit 11, setup unit 12, rewriting unit 13, and the data recovery unit 14 in other embodiments, the function that prompting each unit realizes in detailed below:
