Embodiment
At length set forth to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
The character stream that the character stream that uses during in order to ensure the file encryption after the scanning identification uses when encrypting with original is consistent, and the embodiment of the invention provides a kind of method of processing character, and is as shown in Figure 1, may further comprise the steps:
Pass through foregoing description; Can find out that the method for the processing character that the use embodiment of the invention provides is through changing similar character; Use unified sign to represent, the character stream that the character stream that uses when guaranteeing to scan the file encryption after the identification uses when encrypting with original is consistent.
The method of the processing character that the embodiment of the invention is provided through specific embodiment below is elaborated; Suppose file A is printed spanned file B; Get access to first character stream after file B scanned identification, simultaneously, obtain second character stream in the same position of file A.Use identical transformational relation then, first character stream and second character stream are changed, even like this because the accuracy of identification is not good; To similar character-recognition errors, but through above-mentioned transformational relation, can make the character stream after the conversion identical; And then encrypt etc. when handling; Can not produce mistake, as shown in Figure 2, may further comprise the steps:
Step 201, obtain first character stream among the file A; Concrete; File B is printed to file A, after equipment such as use scanner scan file A, extract its first character stream; During extraction can according to from the top down, or from bottom to top, or begin to extract from certain ad-hoc location, stop modes such as extraction extraction to another ad-hoc location.
Whether there is character to be converted in step 202, detection first character stream, if there is execution in step 203; Otherwise, export this first character stream.
This character to be converted of transformational relation conversion that step 203, basis preset; Concrete; Pre-configured and this transformational relation regularly; It is used for similar character is corresponded to unified sign, judge whether similar similarity degree, the experience and changing with character itself of character whether obscure easily relevant, for example 0, o, O, Q convert 0 into; I, 1, L, l, |,! Convert 1 into; *, *, x, X convert X into; , 3 convert 3 into; { }, [], () convert () into; Z, 2, z convert 2 into; $, s, S convert S etc. into.
Step 204, the character replacement character to be converted after will changing constitute character stream to be detected; Concrete, suppose that first character stream is oz*3s, then replaces with 0 with o; Z replaces with 2; * replace with X; S converts S into; All the other characters are constant, constitute character stream 02X3S to be detected.
Step 205, character stream to be detected and standard character stream is compared; This standard character stream is according to the transformational relation that presets, the character stream that obtains after second character stream among the file B is changed.Wherein, the mode of obtaining this second character stream is identical with the mode of obtaining first character stream, and the transformational relation of following too.
Step 206, if comparison result for the coupling, then output this character stream to be detected.If comparison result for not matching, explains that then this document A is not the printout of file B.
Pass through foregoing description; Can find out that the method for the processing character that the use embodiment of the invention provides is through changing similar character; Use unified sign to represent, the character stream that the character stream that uses when guaranteeing to scan the file encryption after the identification uses when encrypting with original is consistent.
Accordingly, the embodiment of the invention also provides a kind of device of processing character, and is as shown in Figure 3, specifically comprises:
Comparing module 303; Be used for character stream to be detected and standard character stream are compared; The transformational relation that this standard character stream presets for basis; The character stream that obtains after second character stream in the source document of current file changed, and reference position and final position when obtaining said first character stream, corresponding with the reference position of obtaining said second character stream and final position;
Preferable, acquisition module 301 specifically is used to scan this current file and extracts first character stream.
Preferable; Processing module 302; When specifically being used for detecting said first character stream and having character to be converted,, change character to be converted in first character stream according to the transformational relation that presets; Behind character replacement after the conversion character to be converted, constitute character stream to be detected with character non-to be converted in said first character stream.
Preferable, this device also comprises: update module 305 is used for regularly upgrading said transformational relation.
Pass through foregoing description; Can find out that the method and apparatus of the processing character that the use embodiment of the invention provides is through changing similar character; Use unified sign to represent, the character stream that the character stream that uses when guaranteeing to scan the file encryption after the identification uses when encrypting with original is consistent.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
