In some optional realization methods of the present embodiment, above-mentioned above-mentioned text to be shown is encrypted is protected
File may include:Word for word transcoding is carried out to the word that above-mentioned text to be shown includes by the code-transferring method of pre-selection and obtains transcoding
Word obtains protection file by above-mentioned transcoding word.
The code-transferring method of pre-selection can be any one concentrated based on various characters.In addition, the code-transferring method of pre-selection is also
User-defined character set can be used.It should be noted that pre-selection code-transferring method can be based on a certain character set with
The mode of machine transcoding still can be other modes, as long as other modes meet following conditions:1, text to be shown
Do not have between protection file it is apparent, can be by word correspondence that simple mathematical formula describes;2, in text to be shown
Any one word only corresponds to a transcoding word in protection file.3, protect any one transcoding word in file only right
Answer a word in text to be shown.4, there is the code-transferring method of different pre-selections for different texts to be shown, i.e., not
The word correspondence that the code-transferring method of same pre-selection provides should be not exactly the same.
The word that display text is treated by the code-transferring method of pre-selection carries out word for word transcoding, and the word of text to be shown is led to
The character set for crossing the code-transferring method of pre-selection finds corresponding transcoding word, and protection file is built by transcoding word.At this point, can not
By protecting the content of file directly to determine the content of text to be shown, the protection for treating display text is realized.For example, waiting showing
Show the word of text be " in ", the code-transferring method of pre-selection is random transcoding, based on character set be Unicode.Inquiry it is found that
" in " in Unicode it is encoded to 4e2d.Then 4e00,4e00 have been selected in Unicode by way of random transcoding
Word " one " is corresponded in Unicode, then will " in " replace with " one " (that is, establish " and in " word correspondence " one " between
Relationship).Similar, the word in text to be shown is all subjected to transcoding, has just obtained protection file.It should be noted that
When text transmits between server and terminal device, the content of text is all existing in an encoded form.For example, text exists
When being transmitted between server and terminal device, word that text includes be " in " show as coding 4e2d, only in protection file
Be opened display when, the system of server or terminal device can just search the corresponding character images of 4e2d (be shown as " and in " text
Word image), and be displayed on the screen, at this point, user see be only word " in ".Above-mentioned transcoding word is exactly each volume
Code.
Step 203, it determines the word correspondence between above-mentioned text to be shown and above-mentioned protection file, passes through above-mentioned text
Word correspondence obtains cryptogam.
Obtain protection file during, it may be determined that text to be shown and protection file between word it is correspondings pass
System, these word correspondences are saved to obtain cryptogam.
In some optional realization methods of the present embodiment, the above-mentioned above-mentioned text to be shown of determination and above-mentioned protection file
Between word correspondence may comprise steps of:
The first step, word for word determine transcoding word that the above-mentioned text to be shown word that includes includes with above-mentioned protection file it
Between word correspondence, obtain initial word correspondence set.
In the literal code-transfer that text to be shown is included by the character set of the code-transferring method above by pre-selection to protection file
When, it may be determined that the word correspondence between the word that text to be shown includes and the transcoding word for protecting file, that is, one
The word of text to be shown corresponds to the transcoding word of a protection file.Whole word correspondences is built into initial word
Correspondence set.
Second step deletes the word correspondence repeated in above-mentioned initial word correspondence set, obtains secondary word
Correspondence set.
Initial word correspondence set contains complete between the word of text to be shown and the transcoding word for protecting file
The word correspondence in portion.In general, comprising the word much repeated in text to be shown, it is corresponding to have the text much repeated
Word correspondence.And when by protecting the transcoding word of file to obtain the word of text to be shown, as long as each turn can be found
The word correspondence of code word.Therefore, the word repeated in initial word correspondence set can be deleted and correspond to pass
System, the word correspondence in the initial word correspondence set after word correspondence by deleting repetition, structure two
Secondary word correspondence set.I.e. secondary word correspondence set is that the text of repetition is deleted in initial word correspondence set
It is obtained after word correspondence.In order to ensure the accuracy of transcoding, the secondary word in above-mentioned secondary word correspondence set
Correspondence is mapping relations one by one.
In some optional realization methods of the present embodiment, obtaining cryptogam by above-mentioned word correspondence can be with
Include the following steps:
The first step determines the character image with transcoding characters matching by above-mentioned secondary word correspondence.
Cryptogam provides word correspondence for protection file, and by foregoing description, this word correspondence is character
Correspondence after the correspondence of coding and character image changes in collection Unicode.Therefore, it is necessary to according to secondary word
Correspondence determines the character image with transcoding characters matching.
The code-transferring method of pre-selection based on the character set character that includes be typically magnanimity, and for determining text to be shown
For this, many characters in the character set that the code-transferring method of pre-selection includes are not used.So text to be shown can be passed through
The word correspondence of this and protection file, selects text to be shown to use from the corresponding character set of code-transferring method of pre-selection
Character obtains cryptogam.Also by the word of above-mentioned text to be shown be " in " for, it is seen from the above description, to be shown
Word in text be " in " word " one " in corresponding protection file, that is, by word original in character set Unicode " in "
Corresponding coding 4e2d, the corresponding coding 4e00 of word " one ", be revised as word " in " corresponding coding 4e00, that is, establish and be different from
The word of character set Unicode and the correspondence of coding.Then, preserve word " in " character image, and establish the word
The correspondence of image and coding 4e00.That is, cryptogam only have recorded it is encrypted coding it is corresponding with the word of character image
Relationship (i.e. word " in " character image with coding 4e00 correspondence), there is no before recording of encrypted encode and encrypt after compile
Correspondence (correspondence i.e. without record coding 4e2d and encoding 4e00) between code.Therefore, even if user obtains
Cryptogam also voluntarily can not decrypt text to be shown by cryptogam.
Second step generates cryptogam by above-mentioned secondary word correspondence and character image.
Cryptogam can be generated after obtaining secondary word correspondence and character image.
In some optional realization methods of the present embodiment, the above method can also include:Establish protection file with it is close
Query link between code file, above-mentioned query link are used to indicate the above-mentioned above-mentioned cryptogam of protection file polling.

And it establishes cryptogam and protects the query link of file.The query link is used to indicate the above-mentioned above-mentioned password of protection file polling
File.That is, protection file is when opening, it is necessary to which the word correspondence in the cryptogam indicated by query link is to protection
The word of file is inquired, and the character image for including by cryptogam is shown the word in protection file.Example
Such as, the word that the system of server or terminal device is found in protection file is encoded to 4e00, and then finds in cryptogam
Word correspondence be:4e00 correspond to word " in ", then from found in cryptogam word " in " character image, and will
" in " character image be displayed on the screen, what user saw be exactly word " in ".
In some optional realization methods of the present embodiment, the above method can also include the following steps:
The first step, when the word quantity that above-mentioned text to be shown includes is more than given threshold, by above-mentioned text to be shown
It is divided into multiple Ziwen sheets to be shown.
When the word quantity that text to be shown includes is more, and is more than given threshold, text to be shown can be divided
For multiple texts to be shown.For example, text to be shown includes 10000 words, this 10000 strokes can be divided into 10 and wait showing
Show Ziwen sheet.
Second step, for the code-transferring method of each this configuration of Ziwen pre-selection to be shown.
It can be respectively the code-transferring method of each this configuration of Ziwen pre-selection to be shown.Further, Ziwen sheet to be shown it
Between pre-selection code-transferring method it is different, improve the safety of Ziwen sheet to be shown.
