Above-mentioned preparatory condition can be set as needed.For example, judge whether the sender that the data delete instruction is pre-
If sender, it can verify that data delete the sender of instruction by carrying out the modes such as fingerprint authentication or cipher authentication.If data
The sender for deleting instruction is not default sender, then data is not removed completely when deleting, i.e., data are incomplete
Removed from the disk space of terminal, it is recoverable weak deletion that data described in terminal iidentification, which delete the data that instruction instruction is deleted,
Data, the data are hidden in original display location according to the mark, to prevent other users from deleting terminal owner
The data preserved in terminal.
S203：If the data, which delete instruction, meets preparatory condition, identify the data and delete the number that instruction instruction is deleted
According to for recoverable weak deletion data, the data are hidden in original display location according to the mark.
Explanation about step S203 can be found in the description of step S102 in previous embodiment, in the present embodiment described in mark
It is recoverable weak deletion data that data, which delete the data that instruction instruction is deleted, according to the mark by the data original
Display location hides consistent with previous embodiment step S102.
When data, which delete instruction, meets preparatory condition, step S203 operation is just performed, data deletion can carried out
When the different data in terminal are carried out with the deletions of different modes.
Further, above-mentioned data deletion instruction meets that preparatory condition includes：
The weak deletion instruction that the data delete instruction to recover data；And/or
The data delete the data that the data that instruction instruction is deleted are specified type；And/or
It is the data under assigned catalogue that the data, which delete the data that instruction instruction is deleted,；And/or
The data delete the data that the data that instruction instruction is deleted are designated storage area.
The weak deletion instruction that above-mentioned data delete instruction to recover data, i.e., can have at least two in terminal
Kind data delete instruction.Such as it is strong delete instruction and weak delete instructs, it is above-mentioned it is strong delete instruction be used for the data that will delete from
Removed completely on the disk space of terminal, the above-mentioned weak Data Identification for deleting instruction for that will delete is recoverable weak deletion
Data.When the deletion instruction of above-mentioned data is only weak deletion instruction, just performs the data deletion instruction instruction of above-mentioned mark and delete
The data removed are recoverable weak deletion data, the step for being hidden the data in original display location according to the mark
Suddenly.Specifically, user can provide a variety of deletion action buttons in operation, specifically carry out which kind of deletion is grasped for user's selection
Make.It can also give tacit consent to when user deletes and select weak deletion, user, can voluntarily select to delete by force whenever necessary.Meanwhile
The methods of font color can also be passed through, reminds the consequence brought that user deletes by force, for example the font of weak deletion is arranged into green
Color, the font deleted by force is arranged to red, the data that prompting user deletes by force when user selects strong delete can be completely from end
Removed on the disk space at end, it is irrecoverable.
Above-mentioned specified type is can to include but is not limited to mp4 with data type set in advance, such as specified type
The data type of form, the data type of pdf forms, data type of jpg forms etc..When data delete what instruction instruction was deleted
When data are the data of instruction type, it is recoverable just to perform the above-mentioned mark data and delete the data that instruction instruction is deleted
Weak deletion data, the step for being hidden the data in original display location according to the mark.Refer to if data delete instruction
The data for showing deletion are the other kinds of data beyond instruction type, then can use other data-erasure methods or direct
Data are removed from the disk space of terminal.
For example, due to when system upgrade or application renewal when, legacy version (such as number of apk forms of these application files
According to) delete and usually not delete necessity of protection by mistake, and the file or file (such as jpg lattice edited of user that user downloads
The data of formula, data of word forms etc.) it is generally just critically important.Therefore it is jpg and word lattice by the data setting of specified type
Formula data.It is when the data that data delete instruction instruction deletion are the data either data of word forms of jpg forms, then right
The data are identified, and are hidden the data in original display location according to mark.When data delete the number of instruction deletion
During according to data for apk forms, then it is directly removed from the disk space of terminal.
Above-mentioned assigned catalogue is can be with the storing directory of data set in advance, when data delete the number of instruction instruction deletion
During according to being the data being stored under the catalogue specified, just performing the above-mentioned mark data and delete the data that instruction instruction is deleted and be
Recoverable weak deletion data, the step for being hidden the data in original display location according to the mark.If data are deleted
Except instructing the data that instruction is deleted to be the data under other catalogues in addition to being stored in assigned catalogue, then other data can be used
Delet method directly removes data from the disk space of terminal.For example, generally the photo of camera shooting and bluetooth connect
The file of receipts may be important, and the photo of camera shooting is commonly stored under entitled camera catalogue, and bluetooth receives
Data be commonly stored under entitled bluetooth catalogue, therefore specified storing directory can be defined as entitled
The catalogue of camera catalogue and entitled bluetooth.
Above-mentioned designated storage area is can be with the storage address of data set in advance, such as designated storage area is Sdcard.
When the data that data delete instruction instruction deletion are the data being stored in Sdcard, just perform the above-mentioned mark data and delete
Except the data that instruction instruction is deleted are recoverable weak deletion data, according to the mark by the data in original display position
Put hiding step.It is the number being stored in other memory blocks beyond Sdcard that if data, which delete the data that instruction instruction is deleted,
According to can then use and other data-erasure methods or directly remove data from the disk space of terminal.
It is understood that when judging whether data deletion instruction meets preparatory condition, can be by judging data
The no weak deletion data for that can be recovered to data, judge that data delete whether the data that instruction instruction is deleted are specified type
Data, judge that data delete whether the data that instruction instruction is deleted are data under assigned catalogue, judge that data delete instruction
Whether the data for indicating to delete are that any of the data of designated storage area this several determination methods or at least two combine
Row judges, to determine that data delete whether instruction meets preparatory condition, carries out performing corresponding deletion action.
S204：After the data are hidden in original display location, update and show the original display location
Remaining memory capacity.
If certain data markers is weak deletion data, and invisible in original display location, the number will can be originally shown
According to the remaining memory capacity of memory space be updated.
Further, update and show that the remaining memory capacity of the original display location includes：
The current remaining memory capacity in the original display location is added to the size of the data, obtained described original
Display location renewal after remaining memory capacity；
Show the remaining memory capacity after the original display location renewal.
The size for the data being marked will not be included in the size of remaining memory capacity, then the storage that user sees is empty
Between become big really, user is not produced doubt when deleting data, the consistent of interface display and deletion action can be kept
Property.
Due to being identified as the data of weak deletion and non-fully being removed from the disk of terminal, therefore the actual magnetic used
Disk space can be thought more than user.After if actual disk space has been expired, it is still necessary to the magnetic by partial data from terminal
Removed completely on disk, to preserve new data.
In another embodiment of the present invention, data processing method of the present invention also includes：
When the remaining disk space of the terminal is less than target capacity, the disk space by the data from the terminal
Upper removal.
The remaining disk space of above-mentioned terminal is remaining available disk space in terminal.
The size of above-mentioned target capacity can be the fixed value pre-set.Such as the size of target capacity is 20M, then when
When the size of the target capacity of remaining disk space is less than 20M, the disk by the identified data for weak deletion data from terminal
Spatially remove.
The size of above-mentioned target capacity can also be the value of the behaviour in service dynamic change according to terminal.Such as present terminal
The size for the voice data for needing to preserve is 10M, it is determined that the big I of target capacity is 10M.If the now remanence of terminal
When disk space is less than 10M, the identified data for weak deletion data are removed from the disk space of terminal.
Specifically when by being removed on disk space of the data from terminal, interface can be deleted with display data, be selected for user
The data which has been labeled as weak deletion data to are taken to delete.
It can also be and deleted data according to certain priority according to other pre-defined rules.For example, according to wound
The sequencing for building time or last access time is deleted, and is first deleted and is created earliest data or access time earliest number
According to；Either deleted according to the size of data, first delete the data of maximum；Or entered according to the backup instances of data
Row is deleted, and the data for having done backup operation are deleted, and further to improve security when data are deleted, avoids counting
According to loss；It can also be and deleted according to the history access times of data, the minimum data of first deleting history access times.
The method deleted of data for being identified as weak deletion data be not limited to it is above-mentioned several, can be with root
The rule do not mentioned according to other is deleted or random deleted etc..When deleting data, deletion
Size the remaining disk space of terminal can be defined after deletion more than preset capacity, and specific preset capacity can be as needed
Set or and depending on the actual use situation of terminal is random.
The embodiment of the present invention is by after receiving data and deleting instruction, deleting instruction to data and judging, in data
When deletion instruction meets preparatory condition, it is recoverable weak deletion number just to identify the data and delete the data that instruction instruction is deleted
According to the data are hidden in original display location according to the mark.Can be by the data in terminal with different data
Deletion mode is deleted, and the data in terminal is deleted mode more diversification.The anti-error data deleted of needs can be protected,
To not needing the anti-error data deleted to carry out the deletion of other forms, such as directly remove, it is possible to reduce the redundancy of data in terminal.
Hidden simultaneously as data delete the data that instruction instruction is deleted in original display location, therefore in original display location
User can't see the data of deletion so that user thinks that the data have been deleted.And due to data deletion instruction not being referred to
To show the data movement of deletion or removed from disk, the data that data are only deleted to instruction instruction deletion are marked, so
