Description
Technical field
The present invention relates to technical field of mobile terminals, particularly a kind of mobile terminal and prevent privacy leakage method.
Background technology
Along with the development of epoch and mobile terminal, smart mobile phone has become the part in people's work and life, and smart mobile phone is constantly weeded out the old and bring forth the new in addition, and the speed that many users change mobile phone is also more and more faster.How is no mobile phone processed? many users can make a gift to someone or sell by own no old cell phone intelligent mobile phone.In order not reveal privacy, most people can be deleted the private datas such as photo in smart mobile phone, note, address list processing old smart mobile phone money, or recover Default Value, but just genuine like this safety code? this all can not be up hill and dale by clean the information deletion on mobile phone.
At present, the storage device of smart mobile phone is generally flash chip, and useful life is shorter, therefore in the time of storage data, can use abrasion equilibrium technology, after being cleared between certain piece memory block, does not take it as far as possible at once, but looks for a new interval to remove to deposit new data.So the data of mobile phone are updated or delete, be not deletion truly, just between this piece memory block, do individual delete flag.These information are still retained in memory space, at this moment, can be easily by these information revertings out by recovering software, even if " factory reset " is also of no avail.Recoverable information comprises: photo, note, micro-letter chat record, address list, recording, any content of video.
Current intelligent mobile phone system uses the file system such as FAT series substantially, in FAT file system, if create a file, need on disk, open up one " allocation table ", just as the number in library.This table comprises a pointer, points to the address of the content of file.Then system is carried out the read-write of file in the address of pointing to again.Colleague, other file if create, be just prohibited to point to this address, in case file entanglement.And system-kill file is just more convenient: directly " bibliography " destroyed just passable.It is empty that the address that " bibliography " points to is considered to.Because system is to carry out once " lazy " that the consideration in speed is carried out, our information may be detected by uninvited guest.People can, according to the clues and traces on disk, re-establish whole file, or a part for file, thereby spy our privacy.Very disadvantageous to us like that.
