Figure.
Detailed description of the invention
The various exemplary embodiments of the present invention are described in detail now with reference to accompanying drawing.It should also be noted that
Unless specifically stated otherwise, the parts that illustrate the most in these embodiments and step positioned opposite,
Numerical expression and numerical value do not limit the scope of the invention.
Description only actually at least one exemplary embodiment is illustrative below, never makees
For to the present invention and application thereof or any restriction of use.
May not beg in detail for technology, method and apparatus known to person of ordinary skill in the relevant
Opinion, but in the appropriate case, described technology, method and apparatus should be considered a part for description.
Shown here with in all examples discussed, any occurrence should be construed as merely example
Property rather than as limit.Therefore, other example of exemplary embodiment can have different
Value.
It should also be noted that similar label and letter represent similar terms, therefore, one in following accompanying drawing
A certain Xiang Yi the accompanying drawing of denier is defined, then need not it is carried out further in accompanying drawing subsequently
Discuss.
Fig. 1 is the flow chart of the guard method for mobile phone file according to the present invention.
As it is shown in figure 1, in step S110, utilize the application program arranging file access authority to receive
The file safeguard rule of user setup.
Described application program is used for mutual between user or information exchange, for user setup file
Access rights.Such as, described application program provides the connection interface of user, so that user setup file
Safeguard rule.In this way, it is provided that friendly interface, user is made to join intuitively
Put the safeguard rule of file.
In one example, the desktop of mobile phone is placed shortcut icon, such as, condom icon,
User can start user interface by the way of by file drag and drop to this shortcut icon.Example
As, during by user by file drag and drop to shortcut icon, pop-up dialogue box is for the protection arranging file
Rule.In another embodiment, user can be by the way of pressing file for a long time, to eject dish
Single mode starts the safeguard rule arranging file.The safeguard rule of file is set by application program
Mode, the safeguard rule of file can be set or changed in real time, with according to reality when mobile phone runs
Border needs the protection level of file in configurating mobile.
In one example, the safeguard rule of described file include readable, writeable maybe can perform at least
One.
Described file include picture, video, notepad file, word class file, executable file,
Application class software and systems soft ware etc..It will be understood by those of skill in the art that of the present invention
File includes single file, also includes file directory.
In step S120, file safeguard rule described in acquisition also stores.
In order to increase the safety of described file safeguard rule further, in one example, by described
The safeguard rule of file is stored in the safety zone of mobile phone, such as, is deposited by the safeguard rule of described file
Storage is in the encryption memory block of mobile phone.When reading the file safeguard rule stored, need first to carry out
Corresponding deciphering could obtain the safeguard rule of file.In this way, peace can be further enhanced
Quan Xing, reduces the risk that the safeguard rule of described file is modified.
In one example, the safeguard rule of described file is stored in the form of a file, such as,
It is stored as the form of text.The safeguard rule of described file can be stored in the storage medium of mobile phone
In.When the safeguard rule of the file of storage, it is possible that different file safeguard rules has phase
Situation with title.In this case, the safeguard rule of file may produce conflict.Such as,
Posterior file may cover file formerly, thus causes loss of data.
Furthermore, it is also possible to occur that identical file safeguard rule has the situation of different names.This may
Content can be duplicated in the storage medium of mobile phone, and form garbage files, and take mobile phone storage
Resource.
Therefore, in another example, alternatively, the cryptographic Hash using described file safeguard rule is made
Title for described safeguard rule.In this way, above-mentioned file can be avoided to a certain extent
The conflict of safeguard rule and/or rubbish.
Additionally, the transmission of the safeguard rule of file and/or use during, be often damaged
Situation.In some cases, if having invoked the file safeguard rule of damage, being likely to result in and calling journey
The card of sequence pauses and/or collapses.
Therefore, in another embodiment, when reading the safeguard rule of described file, it is also possible to logical
Cross and use the title of file safeguard rule to verify the integrity of described file safeguard rule.By this
Mode, can avoid the generation of the problems referred to above easily by the title of file safeguard rule.
Further, for the risk preventing mobile phone to be physically attacked after losing, such as, by dividing
Analysis chip for cell phone, to obtain the information of user, can carry out full disk encryption to mobile phone.In this way,
The file security in mobile phone can be protected when user shuts down.
In step S130, when receiving the operation requests for described file, the fingerprint of checking user.
Described operation requests includes the reading and writing for file, deletes, revises the operation such as filename.Example
As, when receiving described operation requests, application prompts user inputs fingerprint, and will input
Fingerprint mate with the fingerprint template prestored, if the match is successful, then fingerprint authentication passes through.?
In the case of fingerprint matching is unsuccessful, the operation of refusal user.
In step S140, in the case of the fingerprint of described checking user passes through, it is judged that described operation please
The no safeguard rule meeting described file of Seeking Truth, if met, then allows described operation requests.
User is by, after fingerprint authentication, determining whether whether described operation requests meets described literary composition
The safeguard rule of part, if met, then allows described operation requests.Otherwise, the operation of user is refused
Request.Such as, if the safeguard rule of certain file is set to readable by user, when user ask right
When file renames or revises, then refuse the operation requests of user.
It will be understood to those skilled in the art that at electronic technology field, software, hardware can be passed through
And the mode that software and hardware combines, said method is embodied in the product.Those skilled in the art
Member is easy to, based on method as disclosed above, produce the protection device of a kind of mobile phone file.
