Here it is customized that the file obtained, which saves rule, therefore can save rule using different files according to demand
Then.In order to which the safety of the local file in intelligent terminal is stronger, this document saves rule and can carry out irregularly or regularly
Replacement.After getting customized file preservation rule, will be needed by saving rule according to the file got by one to be protected
Or multiple files are stored in the corresponding position on intelligent terminal.For the ease of the reading of file, can be specified on intelligent terminal
Corresponding memory block is stored.For example, it is desired to the file saved is certain pictures of intelligent terminal local, then it can be according to
The file of acquisition saves rule and these pictures with protection is stored in the picture conservation zone specified on intelligent terminal.
As it can be seen that method of the invention is to save rule according to customized file, by one or more files to be protected
It is saved, to achieve the effect that the protection to file, which improves the safeties of the local file of intelligent terminal, realize
Protection intelligent terminal local file.
After file is saved in the designated storage area of intelligent terminal according to file preservation rule, when the opening for needing to carry out file
When, it is necessary first to file is read out from corresponding memory block, it is in one embodiment of the invention, shown in FIG. 1
Method further comprises: saving rule according to customized file and reads file from the designated storage area of intelligent terminal.Because literary
Part is to be saved according to preservation rule, and have recorded corresponding storage information when saving, if necessary to progress file
It reads, needs to know that file saves rule, and the regular reading for carrying out file from corresponding memory block is saved according to file.The reading
File is taken to be different from opening file, reading file here only reads out file from corresponding memory block, when needs are beaten
When open file, the opening that corresponding decryption rule carries out file can also be further set.
It is as previously mentioned file to save there are many kinds of rules, rule can be saved using different files according to demand.
In one embodiment of the invention, it lists one of file and saves rule: the file header of specific length being written first, it should
File header can recorde the essential informations such as the title of file and storage information etc.；Start to save file then followed by file header
Content.So, in step s 130 according to customized file save rule document to be protected will be needed to be stored in intelligence
The designated storage area of terminal includes: multiple data that continuous equal length is marked off in the designated storage area of intelligent terminal
Area, since it is desired that the file of protection is stored in a specified memory block, for the ease of searching, the data field marked off here
It is equal length, and the length of data field here not necessarily meets the actual occupancy length of file, for example, the number divided
Length according to area is 1000 bytes, and the practical occupancy of the file stored is 800 bytes, this meets the requirement of the present embodiment；
Then, each to need the corresponding data field of document to be protected；When carrying out file preservation, for each data field, In
The storage information that respective file is saved in its preceding first predetermined number byte, second after preceding first predetermined number byte are default
The name information that respective file is saved in number byte, the preservation pair in the region after the second predetermined number byte of the data field
Answer the content of file.It should be noted that the first predetermined number byte and the second predetermined number byte here do not need yet and
The occupancy of the information actually saved is consistent, but need to guarantee corresponding preservation information preservation is complete.
Further, the storage information of the respective file saved in preceding first predetermined number byte includes: file name
Length；File size, such as the length of the practical data field occupied of file.
Above-mentioned file saves rule and is suitable for single file, is also applied for batch documents.If for each file,
The rule of file header and data field can be all made of.For example, the length of the data field divided in entire memory block is 1000
Byte, that is to say, that 0-1000 byte saves first file, and 1001-2000 byte saves the second file, and so on.Because
Here it is the same that file, which saves rule, so being illustrated by taking the rule that first file saves as an example.Corresponding to first
In 1000 bytes of a file, preceding first predetermined number byte is set as 20 bytes, the second predetermined number byte is 10 bytes.
In the data field 0-1000 byte of corresponding first file, what is saved in 0-20 byte is the corresponding storage letter of first file
Breath: file name length and file size.The name information that respective file is saved from 21-30 byte, then in 31-1000 byte
The content of respective file can be saved.That is preceding 30 bytes here are considered the file header of respective file.
So in the above example, when carrying out the reading of file, so that it may according to filename corresponding in file header
The length of length and file is claimed to be read out, for example, the file name length that 0-20 byte saves is 8 in 0-1000 byte,
File size is 500, it follows that 8 bytes are the title of file before in the second predetermined number byte of 0-1000 byte,
500 bytes are the contents of file before in the region after the second predetermined number byte, i.e., 21-28 byte be file name
Claim, in the content that 31-530 is file, carry out reading 21-28 byte and 31-530 byte when file reading, so that it may
File to be read out.
In another specific example, the method for the protection intelligent terminal local file can be in user's intelligent terminal
In attending to anything else.The a certain application software for needing login account is not allow to log in two simultaneously in intelligent terminal under normal conditions

To log in two accounts simultaneously.For example, wechat application, may log into two wechat accounts using attending to anything else, user can be simultaneously
Personal account and work account are logged in, the experience of user is enhanced.But the secrecy of a certain account is carried out if necessary, such as can
It is related to the work account of business secret, then the guard method of the file in the technical program can be used.Herein to protect
It protects for good friend's head portrait in wechat work account, because good friend's image may expose the customer information in work.So
With regard to providing that each head portrait is necessarily less than 1K, setting 0-1000 belongs to first head portrait file, and 1000-2000 belongs to second head portrait
File, and so on.In this head portrait file of 0-1000, the storage information of preceding 16 byte records files, the 17-64 word
Section is the name of file, is exactly its content then after 64 bytes, i.e. the specific content of head portrait.Here first 16
Byte just has recorded file and stores in the initial position of memory block, the length of name, the initial position of content, length of content etc.
Information.
If it is batch documents, then batch documents are directed to, it is whole only with a file header, then in several equal lengths
Data field storage batch documents name information and file content.In one embodiment of the invention, in step S130
Saving rule document to be protected will be needed to be stored in the designated storage area of intelligent terminal according to customized file includes: in intelligence
The data field of file head region and multiple equal lengths is marked off in the designated storage area of terminal, file header and data field here
It need to be continuous；It is each to need the corresponding data field of document to be protected；It is saved in file head region: file size and file
Number；For each data field, the name information of respective file is saved in its preceding first predetermined number byte, in the data field
The first predetermined number byte after region in save respective file content.
Each of in one example, if the file saved is several pictures, divided in entire memory block
The length in image data area is 1000 bytes, and dividing file header is 20 bytes, that is to say, that 20-1020 byte saves the
One picture, 1021-2020 byte save second picture, and so on.File size and guarantor are saved in 20 byte of file header
The number for the picture deposited.Then it is corresponding in turn to after 21 bytes and saves each picture, the data field that each picture here saves
In be additionally added the name information of every picture.The first predetermined number byte is set as 15 bytes, i.e., preceding 15 word of each data field
Section saves the title of corresponding picture.For example, the picture that corresponding 20-1020 byte saves, what 21-35 was saved is the picture pair
The title answered, 36-1020 save the content of picture.Meanwhile it also can be reserved for and corresponding in preceding first predetermined number byte here
The length of picture.
Here need to carry out the acquisition that file saves rule before carrying out file preservation, file saves rule and can protect in advance
It deposits in an intelligent terminal, can also be obtained in real time from server end.So in one embodiment of the invention, step
It includes: to obtain customized file from given server to save rule that the customized file of acquisition in S110, which saves rule,；Or

In parameter update.One of file is already indicated above in the above description and saves rule as the text of write-in specific length first
Part head starts the content for saving file then followed by file header.It so can when carrying out the update of file safeguard rule
Not use the rule, a rule is redefined；It can continue to using the rule, then can be by changing file
The length of parameter or file header and data area in head is updated.For example, file header is 20 bytes, the data of file
The length in area is 1000 bytes, then can update are as follows: file header is 30 bytes, and the length of the data field of file is 1500 words
Section.
When file is read out, the memory block that rule is specified in an intelligent terminal can be saved according to file and is carried out
It reads.Certain decryption rule can also be so pre-saved when opening file saves rule to customized file is got
