For solving the problems of the technologies described above, the embodiment of the present invention provides a kind of method of data crushing, after being applied to and sending data to other-end.Fig. 1 shows the processing flow chart of the method for data crushing according to an embodiment of the invention.Referring to Fig. 1, this flow process at least comprises that step S102 is to step S104.
Step S102, specified data end of transmission.
Step S104, the local data of having transmitted of pulverizing, cannot recover it.
The data crushing method providing according to the embodiment of the present invention, can be after specified data end of transmission, pulverizes the local data of having transmitted, and it cannot be recovered.Because data are divided into two parts after depositing hard disk in, a part is real data, another part is the index for authentic data, and only the index part in hard disk can be deleted the deletion action of data in prior art, and data division is designated to countless certificates, so that system continues the new data of storage.Therefore, deletion action of the prior art cannot ensure to have deleted data and not be resumed, and after more cannot ensureing to delete, can not be revealed for the higher file of some confidentialities.For example, carry some account information data and passwords thereof of user in the note data of user mobile phone, the contact data of user mobile phone is resumed easily and causes " fishing " event to make friends and family's property cheated etc.In the embodiment of the present invention; can be after specified data end of transmission; pulverize the local data of having transmitted; it cannot be recovered; solve and in prior art, data have manually been deleted and/or terminal is carried out to the problem that user data cannot be thoroughly deleted in the operation of factory reset, reached and more rationally protect efficiently user information safety and/or the not compromised beneficial effect of protection individual subscriber private data.
In the embodiment of the present invention, before the data that this locality has been transmitted are carried out crushing operation, obtain local data processing authority.Wherein, due in practical operation, process and need to obtain different authorities for the data of the different application of terminal, and ROOT authority can cover the authority that most of data are processed, therefore the data processing authority of, obtaining in the embodiment of the present invention comprises ROOT authority.In practical operation, the data processing authority of terminal this locality is comprised to interim ROOT authority and permanent ROOT authority.Wherein, compared with permanent ROOT authority, interim ROOT authority refers to temporary ROOT authority, and, after terminal restarts, interim ROOT authority can disappear automatically.But get after interim ROOT authority to the operating right of data with obtain permanent ROOT authority after identical to the operation claim of data.
For example, the operation that gets interim ROOT authority comprises: the internal processes operation of operation that system file is backed up, amendment system, set up applications are obtained arbitrarily the operating right after permanent ROOT authority to the unloading operation of the fitting operation of mourning in silence that obtains operation, application program, application program and/or the system pre-installed applications program of operation, system file and/or the application file catalogue of safe digital card (Secure Digital Memory Card, hereinafter to be referred as SD card) etc.Therefore, in the embodiment of the present invention, obtain the processing authority that interim ROOT authority guarantees to obtain the data to terminal this locality, and ensure after data are carried out to pulverization process, interim ROOT authority can disappear automatically, avoid, owing to obtaining permanent ROOT authority, causing user to lose for the maintenance free of this terminal and the service of maintenance.
In the embodiment of the present invention, can judge the current interim ROOT authority of whether having obtained, and determine whether to process the data of terminal this locality according to judged result.For example, the embodiment of the present invention can be passed through the order of adb shell id, obtains active user's ID rank.If ID=0, represents that active user has obtained interim ROOT authority.Above mention, get ROOT authority and be the highest rights of using of the system that gets terminal.User's ID=0 represents current this highest weight limit that got, and active user has obtained interim ROOT authority.
For example, in the time that the system of terminal is Android system, concrete carries out as given an order:
shell:su-c?mount-o?remount?rw/system/app/system/app
Wherein, this instruction utilizes the shell-command of adb mentioned above to obtain active user's ID rank.And, utilize su in shell-command to add mount-0remount order to destination path (/system/app), thus general/system/app is made as read-write (being the rw in instruction) state.Wherein, the su in shell-command represents that high rights of using are acquired, and can start use, for example, obtain the interim ROOT authority in this example.
In addition, in practical operation, exist the embodiment of the present invention cannot directly obtain the type of the terminal of ROOT authority, in this kind of situation, need user to obtain by other means as required the ROOT authority of terminal.After obtaining, this ROOT authority is carried out to Authorized operation.The method that afterwards, can use the data crushing that the embodiment of the present invention provides the processing such as pulverizes to the data that receive.
Above mention, after obtaining local data processing authority, the embodiment of the present invention is carried out the crushing operation that cannot recover to data.In practical operation, the difference that is provided with data in the different operating system of different terminals is deposited rule, and in the storing directory of depositing regulation different pieces of information in rule.The name of the storing directory of the data that for example, specify all application in the Android system of mobile phone in mobile phone EMS memory is called " data ".Further, in this " data " catalogue, be application distribution catalogue, and according to the bag name of different application, the catalogue of distributing named.In addition, it can be the rule of depositing arranging in the operating system of terminal that the difference existing for different application is deposited rule, can also be the rule of depositing arranging in to the compiling procedure of application.And the data in the storing directory of application only can be carried out read-write operation by this application, and each application also only can be carried out read-write operation to its corresponding catalogue.
For example, the storing directory (also can be called deposit path) of the application data of micro-letter in mobile phone EMS memory is: mobile phone EMS memory-data-weixindata.In addition, the image data of micro-letter can be deposited in the storing directory arranging in the SD card of mobile phone, and this storing directory is: SD card-weixin-picture.Wherein " weixin " is the phonetic spelling of " micro-letter ".Again for example, the game class in mobile phone is applied in the storing directory in mobile phone EMS memory and is: mobile phone EMS memory-data-youxidata.In addition, game class application can also arrange storing directory in SD card, is: SD card-zhaonimeidata, and the progress data of storage game in this storing directory as game " look for you younger sister " can arrange storing directory in SD card.Wherein, " zhaonimei " is the phonetic spelling of " look for you younger sister ".
Therefore, for ensureing in the time that the data to local are carried out crushing operation, can find more all sidedly and relate to the data of user privacy information and/or property information etc. and it is carried out to crushing operation, and avoid because the improper deletion of the data in terminal or application causes the operating system paralysis of terminal or unavailable, and then affect the problem of the use of user to terminal, the embodiment of the present invention is obtained the deposit data rule of different application, and by the deposit data rale store getting in database.Before the data to local are carried out crushing operation, the embodiment of the present invention travels through the data of depositing in terminal, obtains the storing directory of total data in terminal.According to the deposit data rule getting, data and storing directory thereof that traversal is obtained are analyzed.For example, if specified data is that terminal is used to the data (application data of third party's application of installing) without impact, can directly carry out crushing operation to data.If the data that specified data is terminal operating system, are further analyzed these data, when determining cannot affect the normal running of terminal system to the crushing operation of data time, can directly carry out crushing operation to data.
In the time that data are carried out to crushing operation, because data are divided into two parts after depositing hard disk in, a part is real data, another part is the index for authentic data, and in the manual deletion action of prior art, only the index part in hard disk is deleted, and data division is designated to countless certificates, so that system continues the new data of storage.Therefore, manual deletion action of the prior art cannot ensure to have deleted data and not be resumed, and after more cannot ensureing to delete, can not be revealed for the higher file of some confidentialities.For example, carry some account information data and passwords thereof of user in the note data of user mobile phone, the contact data of user mobile phone is resumed easily and causes " fishing " event to make friends and family's property cheated etc.
